Description
DESCRIPTION OF PARTICULAR EMBODIMENTS OF THE INVENTION
[0188] Unless contraindicated or noted otherwise, in these descriptions and throughout this specification, the terms a and an mean one or more, the term or means and/or. It is understood that the examples and embodiments described herein are for illustrative purposes only and that various modifications or changes in light thereof will be suggested to persons skilled in the art and are to be included within the spirit and purview of this application and scope of the appended claims. All publications, patents, and patent applications cited herein, including citations therein, are hereby incorporated by reference in their entirety for all purposes.
[0189] The term alkyl refers to a hydrocarbon group selected from linear and branched saturated hydrocarbon groups of 1-18, or 1-12, or 1-6 carbon atoms. Examples of the alkyl group include methyl, ethyl, 1-propyl or n-propyl (n-Pr), 2-propyl or isopropyl (i-Pr), 1-butyl or n-butyl (n-Bu), 2-methyl-1-propyl or isobutyl (i-Bu), 1-methylpropyl or s-butyl (s-Bu), and 1,1-dimethylethyl or t-butyl (t-Bu). Other examples of the alkyl group include 1-pentyl, 2-pentyl, 3-pentyl, 2-methyl-2-butyl, 3-methyl-2-butyl, 3-methyl-1-butyl, 2-methyl-1-butyl, 1-hexyl, 2-hexyl, 3-hexyl, 2-methyl-2-pentyl, 3-methyl-2-pentyl, 4-methyl-2-pentyl, 3-methyl-3-pentyl, 2-methyl-3-pentyl, 2,3-dimethyl-2-butyl and 3,3-dimethyl-2-butyl groups.
[0190] Lower alkyl means 1-8, preferably 1-6, more preferably 1-4 carbon atoms; lower alkenyl or alkynyl means 2-8, 2-6 or 2-4 carbon atoms.
[0191] The term alkenyl refers to a hydrocarbon group selected from linear and branched hydrocarbon groups comprising at least one CC double bond and of 2-18, or 2-12, or 2-6 carbon atoms. Examples of the alkenyl group may be selected from ethenyl or vinyl, prop-1-enyl, prop-2-enyl, 2-methylprop-1-enyl, but-1-enyl, but-2-enyl, but-3-enyl, buta-1,3-dienyl, 2-methylbuta-1,3-diene, hex-1-enyl, hex-2-enyl, hex-3-enyl, hex-4-enyl, and hexa-1,3-dienyl groups.
[0192] The term alkynyl refers to a hydrocarbon group selected from linear and branched hydrocarbon group, comprising at least one CC triple bond and of 2-18, or 2-12, or 2-6 carbon atoms. Examples of the alkynyl group include ethynyl, 1-propynyl, 2-propynyl (propargyl), 1-butynyl, 2-butynyl, and 3-butynyl groups.
[0193] The term cycloalkyl refers to a hydrocarbon group selected from saturated and partially unsaturated cyclic hydrocarbon groups, comprising monocyclic and polycyclic (e.g., bicyclic and tricyclic) groups. For example, the cycloalkyl group may be of 3-12, or 3-8, or 3-6 carbon atoms. Even further for example, the cycloalkyl group may be a monocyclic group of 3-12, or 3-8, or 3-6 carbon atoms. Examples of the monocyclic cycloalkyl group include cyclopropyl, cyclobutyl, cyclopentyl, 1-cyclopent-1-enyl, 1-cyclopent-2-enyl, 1-cyclopent-3-enyl, cyclohexyl, 1-cyclohex-1-enyl, 1-cyclohex-2-enyl, 1-cyclohex-3-enyl, cyclohexadienyl, cycloheptyl, cyclooctyl, cyclononyl, cyclodecyl, cycloundecyl, and cyclododecyl groups. Examples of the bicyclic cycloalkyl groups include those having 7-12 ring atoms arranged as a bicycle ring selected from [4,4], [4,5], [5,5], [5,6] and [6,6] ring systems, or as a bridged bicyclic ring selected from bicyclo[2.2.1]heptane, bicyclo[2.2.2]octane, and bicyclo[3.2.2]nonane. The ring may be saturated or have at least one double bond (i.e. partially unsaturated), but is not fully conjugated, and is not aromatic, as aromatic is defined herein.
[0194] The term aryl herein refers to a group selected from: 5- and 6-membered carbocyclic aromatic rings, for example, phenyl; bicyclic ring systems such as 7-12 membered bicyclic ring systems wherein at least one ring is carbocyclic and aromatic, selected, for example, from naphthalene, indane, and 1,2,3,4-tetrahydroquinoline; and tricyclic ring systems such as 10-15 membered tricyclic ring systems wherein at least one ring is carbocyclic and aromatic, for example, fluorene.
[0195] For example, the aryl group is selected from 5- and 6-membered carbocyclic aromatic rings fused to a 5- to 7-membered cycloalkyl or heterocyclic ring optionally comprising at least one heteroatom selected from N, O, and S, provided that the point of attachment is at the carbocyclic aromatic ring when the carbocyclic aromatic ring is fused with a heterocyclic ring, and the point of attachment can be at the carbocyclic aromatic ring or at the cycloalkyl group when the carbocyclic aromatic ring is fused with a cycloalkyl group. Bivalent radicals formed from substituted benzene derivatives and having the free valences at ring atoms are named as substituted phenylene radicals. Bivalent radicals derived from univalent polycyclic hydrocarbon radicals whose names end in -yl by removal of one hydrogen atom from the carbon atom with the free valence are named by adding -idene to the name of the corresponding univalent radical, e.g., a naphthyl group with two points of attachment is termed naphthylidene. Aryl, however, does not encompass or overlap with heteroaryl, separately defined below. Hence, if one or more carbocyclic aromatic rings are fused with a heterocyclic aromatic ring, the resulting ring system is heteroaryl, not aryl, as defined herein.
[0196] The term halogen or halo refers to F, Cl, Br or I.
[0197] The term heteroalkyl refers to alkyl comprising at least one heteroatom.
[0198] The term heteroaryl refers to a group selected from: [0199] 5- to 7-membered aromatic, monocyclic rings comprising 1, 2, 3 or 4 heteroatoms selected from N, O, and S, with the remaining ring atoms being carbon; [0200] 8- to 12-membered bicyclic rings comprising 1, 2, 3 or 4 heteroatoms, selected from N, O, and S, with the remaining ring atoms being carbon and wherein at least one ring is aromatic and at least one heteroatom is present in the aromatic ring; and [0201] 11- to 14-membered tricyclic rings comprising 1, 2, 3 or 4 heteroatoms, selected from N, O, and S, with the remaining ring atoms being carbon and wherein at least one ring is aromatic and at least one heteroatom is present in an aromatic ring.
[0202] For example, the heteroaryl group includes a 5- to 7-membered heterocyclic aromatic ring fused to a 5- to 7-membered cycloalkyl ring. For such fused, bicyclic heteroaryl ring systems wherein only one of the rings comprises at least one heteroatom, the point of attachment may be at the heteroaromatic ring or at the cycloalkyl ring.
[0203] When the total number of S and O atoms in the heteroaryl group exceeds 1, those heteroatoms are not adjacent to one another. In some embodiments, the total number of S and O atoms in the heteroaryl group is not more than 2. In some embodiments, the total number of S and O atoms in the aromatic heterocycle is not more than 1.
[0204] Examples of the heteroaryl group include, but are not limited to, (as numbered from the linkage position assigned priority 1) pyridyl (such as 2-pyridyl, 3-pyridyl, or 4-pyridyl), cinnolinyl, pyrazinyl, 2,4-pyrimidinyl, 3,5-pyrimidinyl, 2,4-imidazolyl, imidazopyridinyl, isoxazolyl, oxazolyl, thiazolyl, isothiazolyl, thiadiazolyl, tetrazolyl, thienyl, triazinyl, benzothienyl, furyl, benzofuryl, benzoimidazolyl, indolyl, isoindolyl, indolinyl, phthalazinyl, pyrazinyl, pyridazinyl, pyrrolyl, triazolyl, quinolinyl, isoquinolinyl, pyrazolyl, pyrrolopyridinyl (such as 1H-pyrrolo[2,3-b]pyridin-5-yl), pyrazolopyridinyl (such as 1H-pyrazolo[3,4-b]pyridin-5-yl), benzoxazolyl (such as benzo[d]oxazol-6-yl), pteridinyl, purinyl, 1-oxa-2,3-diazolyl, 1-oxa-2,4-diazolyl, 1-oxa-2,5-diazolyl, 1-oxa-3,4-diazolyl, 1-thia-2,3-diazolyl, 1-thia-2,4-diazolyl, 1-thia-2,5-diazolyl, 1-thia-3,4-diazolyl, furazanyl, benzofurazanyl, benzothiophenyl, benzothiazolyl, benzoxazolyl, quinazolinyl, quinoxalinyl, naphthyridinyl, furopyridinyl, benzothiazolyl (such as benzo[d]thiazol-6-yl), indazolyl (such as 1H-indazol-5-yl) and 5,6,7,8-tetrahydroisoquinoline.
[0205] The term heterocyclic or heterocycle or heterocyclyl refers to a ring selected from 4- to 12-membered monocyclic, bicyclic and tricyclic, saturated and partially unsaturated rings comprising at least one carbon atoms in addition to 1, 2, 3 or 4 heteroatoms, selected from oxygen, sulfur, and nitrogen. Heterocycle also refers to a 5- to 7-membered heterocyclic ring comprising at least one heteroatom selected from N, O, and S fused with 5-, 6-, and/or 7-membered cycloalkyl, carbocyclic aromatic or heteroaromatic ring, provided that the point of attachment is at the heterocyclic ring when the heterocyclic ring is fused with a carbocyclic aromatic or a heteroaromatic ring, and that the point of attachment can be at the cycloalkyl or heterocyclic ring when the heterocyclic ring is fused with cycloalkyl.
[0206] Heterocycle also refers to an aliphatic spirocyclic ring comprising at least one heteroatom selected from N, O, and S, provided that the point of attachment is at the heterocyclic ring. The rings may be saturated or have at least one double bond (i.e. partially unsaturated). The heterocycle may be substituted with oxo. The point of the attachment may be carbon or heteroatom in the heterocyclic ring. A heterocyle is not a heteroaryl as defined herein.
[0207] Examples of the heterocycle include, but not limited to, (as numbered from the linkage position assigned priority 1) 1-pyrrolidinyl, 2-pyrrolidinyl, 2,4-imidazolidinyl, 2,3-pyrazolidinyl, 1-piperidinyl, 2-piperidinyl, 3-piperidinyl, 4-piperidinyl, 2,5-piperazinyl, pyranyl, 2-morpholinyl, 3-morpholinyl, oxiranyl, aziridinyl, thiiranyl, azetidinyl, oxetanyl, thietanyl, 1,2-dithietanyl, 1,3-dithietanyl, dihydropyridinyl, tetrahydropyridinyl, thiomorpholinyl, thioxanyl, piperazinyl, homopiperazinyl, homopiperidinyl, azepanyl, oxepanyl, thiepanyl, 1,4-oxathianyl, 1,4-dioxepanyl, 1,4-oxathiepanyl, 1,4-oxaazepanyl, 1,4-dithiepanyl, 1,4-thiazepanyl and 1,4-diazepane 1,4-dithianyl, 1,4-azathianyl, oxazepinyl, diazepinyl, thiazepinyl, dihydrothienyl, dihydropyranyl, dihydrofuranyl, tetrahydrofuranyl, tetrahydrothienyl, tetrahydropyranyl, tetrahydrothiopyranyl, 1-pyrrolinyl, 2-pyrrolinyl, 3-pyrrolinyl, indolinyl, 2H-pyranyl, 4H-pyranyl, 1,4-dioxanyl, 1,3-dioxolanyl, pyrazolinyl, pyrazolidinyl, dithianyl, dithiolanyl, pyrazolidinylimidazolinyl, pyrimidinonyl, 1,1-dioxo-thiomorpholinyl, 3-azabicyco [3.1.0]hexanyl, 3-azabicyclo[4.1.0]heptanyl and azabicyclo[2.2.2]hexanyl. Substituted heterocycle also includes ring systems substituted with one or more oxo moieties, such as piperidinyl N-oxide, morpholinyl-N-oxide, 1-oxo-1-thiomorpholinyl and 1, 1-dioxo-1-thiomorpholinyl.
[0208] Substituents are selected from: halogen, R, OR, O, NR, NOR, NRR, SR, SiRRR, OC(O)R, C(O)R, CO.sub.2R, CONRR, OC(O)NRR, NRC(O)R, NRC(O)NRR, NRSO.sub.2NR, NRCO.sub.2R, NHC(NH.sub.2)NH, NRC(NH.sub.2)NH, NHC(NH.sub.2)NR, S(O)R, SO.sub.2R, SO.sub.2NRR, NRSO.sub.2R, CN and NO.sub.2, N.sub.3, CH(Ph).sub.2, perfluoro (C1-C4)alkoxy and perfluoro (C1-C4)alkyl, in a number ranging from zero to three, with those groups having zero, one or two substituents being particularly preferred. R, R and R each independently refer to hydrogen, unsubstituted (C1-C8)alkyl and heteroalkyl, unsubstituted aryl, aryl substituted with one to three halogens, unsubstituted alkyl, alkoxy or thioalkoxy groups, or aryl-(C1-C4)alkyl groups. When R and R are attached to the same nitrogen atom, they can be combined with the nitrogen atom to form a 5-, 6- or 7-membered ring. Hence, NRR includes 1-pyrrolidinyl and 4-morpholinyl, alkyl includes groups such as trihaloalkyl (e.g., CF.sub.3 and CH.sub.2CF.sub.3), and when the aryl group is 1,2,3,4-tetrahydronaphthalene, it may be substituted with a substituted or unsubstituted (C3-C7)spirocycloalkyl group. The (C3-C7)spirocycloalkyl group may be substituted in the same manner as defined herein for cycloalkyl.
[0209] Preferred substituents are selected from: halogen, R, OR, O, NRR, SR, SiRRR, OC(O)R, C(O)R, CO.sub.2R, CONRR, OC(O)NRR, NRC(O)R, NRCO.sub.2R, NRSO.sub.2NRR, S(O)R, SO.sub.2R, SO.sub.2NRR, NRSO.sub.2R, CN and NO.sub.2, perfluoro (C1-C4)alkoxy and perfluoro (C1-C4)alkyl, where R and R are as defined above.
[0210] The term fused ring herein refers to a polycyclic ring system, e.g., a bicyclic or tricyclic ring system, in which two rings share only two ring atoms and one bond in common. Examples of fused rings may comprise a fused bicyclic cycloalkyl ring such as those having from 7 to 12 ring atoms arranged as a bicyclic ring selected from [4,4], [4,5], [5,5], [5,6] and [6,6] ring systems as mentioned above; a fused bicylclic aryl ring such as 7 to 12 membered bicyclic aryl ring systems as mentioned above, a fused tricyclic aryl ring such as 10 to 15 membered tricyclic aryl ring systems mentioned above; a fused bicyclic heteroaryl ring such as 8- to 12-membered bicyclic heteroaryl rings as mentioned above, a fused tricyclic heteroaryl ring such as 11- to 14-membered tricyclic heteroaryl rings as mentioned above; and a fused bicyclic or tricyclic heterocyclyl ring as mentioned above.
[0211] The compounds may contain an asymmetric center and may thus exist as enantiomers. Where the compounds possess two or more asymmetric centers, they may additionally exist as diastereomers. Enantiomers and diastereomers fall within the broader class of stereoisomers. All such possible stereoisomers as substantially pure resolved enantiomers, racemic mixtures thereof, as well as mixtures of diastereomers are intended to be included. All stereoisomers of the compounds and/or pharmaceutically acceptable salts thereof are intended to be included. Unless specifically mentioned otherwise, reference to one isomer applies to any of the possible isomers. Whenever the isomeric composition is unspecified, all possible isomers are included.
[0212] The compounds of the invention may also contain unnatural proportions of atomic isotopes at one or more of the atoms that constitute such compounds, such as deuterium, e.g. CD.sub.3, CD.sub.2H or CDH.sub.2 in place of methyl. For example, the compounds may be radiolabeled with radioactive isotopes, such as for example tritium (.sup.3H), iodine-125 (.sup.125I) or carbon-14 (.sup.14C). All isotopic variations of the compounds of the invention, whether radioactive or not, are intended to be encompassed within the scope of the invention.
[0213] The term substantially pure means that the target stereoisomer contains no more than 35%, such as no more than 30%, further such as no more than 25%, even further such as no more than 20%, by weight of any other stereoisomer(s). In some embodiments, the term substantially pure means that the target stereoisomer contains no more than 10%, for example, no more than 5%, such as no more than 1%, by weight of any other stereoisomer(s).
[0214] When compounds contain olefin double bonds, unless specified otherwise, such double bonds are meant to include both E and Z geometric isomers.
[0215] Some of the compounds may exist with different points of attachment of hydrogen, referred to as tautomers. For example, compounds including carbonyl CH.sub.2C(O) groups (keto forms) may undergo tautomerism to form hydroxyl CHC(OH) groups (enol forms). Both keto and enol forms, individually as well as mixtures thereof, are also intended to be included where applicable.
[0216] It may be advantageous to separate reaction products from one another and/or from starting materials. The desired products of each step or series of steps is separated and/or purified (hereinafter separated) to the desired degree of homogeneity by the techniques common in the art. Typically such separations involve multiphase extraction, crystallization from a solvent or solvent mixture, distillation, sublimation, or chromatography. Chromatography can involve any number of methods including, for example: reverse-phase and normal phase; size exclusion; ion exchange; high, medium and low pressure liquid chromatography methods and apparatus; small scale analytical; simulated moving bed (SMB) and preparative thin or thick layer chromatography, as well as techniques of small scale thin layer and flash chromatography. One skilled in the art will apply techniques most likely to achieve the desired separation.
[0217] Diastereomeric mixtures can be separated into their individual diastereomers on the basis of their physical chemical differences by methods well known to those skilled in the art, such as by chromatography and/or fractional crystallization. Enantiomers can be separated by converting the enantiomeric mixture into a diastereomeric mixture by reaction with an appropriate optically active compound (e.g., chiral auxiliary such as a chiral alcohol or Mosher's acid chloride), separating the diastereomers and converting (e.g., hydrolyzing) the individual diastereoisomers to the corresponding pure enantiomers. Enantiomers can also be separated by use of a chiral HPLC column.
[0218] A single stereoisomer, e.g., a substantially pure enantiomer, may be obtained by resolution of the racemic mixture using a method such as formation of diastereomers using optically active resolving agents. Racemic mixtures of chiral compounds of the invention can be separated and isolated by any suitable method, including: (1) formation of ionic, diastereomeric salts with chiral compounds and separation by fractional crystallization or other methods, (2) formation of diastereomeric compounds with chiral derivatizing reagents, separation of the diastereomers, and conversion to the pure stereoisomers, and (3) separation of the substantially pure or enriched stereoisomers directly under chiral conditions.
[0219] Pharmaceutically acceptable salts include, but are not limited to salts with inorganic acids, selected, for example, from hydrochlorates, phosphates, diphosphates, hydrobromates, sulfates, sulfinates, and nitrates; as well as salts with organic acids, selected, for example, from malates, maleates, fumarates, tartrates, succinates, citrates, lactates, methanesulfonates, p-toluenesulfonates, 2-hydroxyethylsulfonates, benzoates, salicylates, stearates, alkanoates such as acetate, and salts with HOOC(CH.sub.2)n-COOH, wherein n is selected from 0 to 4. Similarly, examples of pharmaceutically acceptable cations include, but are not limited to, sodium, potassium, calcium, aluminum, lithium, and ammonium.
[0220] In addition, if a compound is obtained as an acid addition salt, the free base can be obtained by basifying a solution of the acid salt. Conversely, if the product is a free base, an addition salt, such as a pharmaceutically acceptable addition salt, may be produced by dissolving the free base in a suitable organic solvent and treating the solution with an acid, in accordance with conventional procedures for preparing acid addition salts from base compounds. Those skilled in the art will recognize various synthetic methodologies that may be used without undue experimentation to prepare non-toxic pharmaceutically acceptable addition salts.
[0221] Treating, treat, or treatment refers to administering at least one compound and/or at least one stereoisomer thereof, and/or at least one pharmaceutically acceptable salt thereof to a subject in recognized need thereof.
[0222] An effective amount refers to an amount of at least one compound and/or at least one stereoisomer thereof, and/or at least one pharmaceutically acceptable salt thereof effective to treat a disease or disorder in a subject, and that will elicit, to some significant extent, the biological or medical response of a tissue, system, animal or human that is being sought, such as when administered, is sufficient to prevent development of, or alleviate to some extent, one or more of the symptoms of the condition or disorder being treated. The therapeutically effective amount will vary depending on the compound, the disease and its severity and the age, weight, etc., of the mammal to be treated.
[0223] The term at least one substituent includes, for example, from 1 to 4, such as from 1 to 3, further as 1 or 2, substituents. For example, at least one substituent R herein includes from 1 to 4, such as from 1 to 3, further as 1 or 2, substituents selected from the list of R as described herein.
[0224] The subject compounds and stereoisomers thereof, and pharmaceutically acceptable salts thereof may be employed alone or in combination with at least one other therapeutic agent for treatment.

[0235] The dosage administered will be dependent on factors, such as the age, health and weight of the recipient, the extent of disease, type of concurrent treatment, if any, frequency of treatment, and the nature of the effect desired. In general, a daily dosage of the active ingredient can vary, for example, from 0.1 to 2000 milligrams per day. For example, 10-500 milligrams once or multiple times per day may be effective to obtain the desired results.
[0236] In some embodiments, a large number of unit capsules can be prepared by filling standard two-piece hard gelatin capsules each with, for example, 100 milligrams of the subject compound and stereoisomers thereof, and pharmaceutically acceptable salt thereof disclosed herein in powder, 150 milligrams of lactose, 50 milligrams of cellulose, and 6 milligrams magnesium stearate.

[0241] The same dosage forms can generally be used when the compound, stereoisomers thereof, and pharmaceutically acceptable salts thereof are administered stepwise or in conjunction with at least one other therapeutic agent. When drugs are administered in physical combination, the dosage form and administration route should be selected depending on the compatibility of the combined drugs. Thus the term coadministration is understood to include the administration of at least two agents concomitantly or sequentially, or alternatively as a fixed dose combination of the at least two active components.
[0242] The compounds, stereoisomers thereof, and pharmaceutically acceptable salt thereof disclosed herein can be administered as the sole active ingredient or in combination with at least one second active ingredient.
[0243] The subject compounds are incorporated into pharmaceutical compositions or formulations. The compositions will contain pharmaceutically acceptable diluents and/or carriers, i.e. diluents or carriers that are physiologically compatible and substantially free from pathogenic impurities. Suitable excipients or carriers and methods for preparing administrable compositions are known or apparent to those skilled in the art and are described in more detail in such publications as Remington's Pharmaceutical Science, Mack Publishing Co, NJ. The compositions may also be in the form of controlled release or sustained release compositions as known in the art. For many applications the subject compounds are administered for morning/daytime dosing, with off period at night.
[0244] The subject compounds may be used per se, or in the form of their pharmaceutically acceptable salts, such as hydrochlorides, hydrobromides, acetates, sulfates, citrates, carbonates, trifluoroacetates and the like. When compounds contain relatively acidic functionalities, salts can be obtained by addition of the desired base, either neat or in a suitable inert solvent. Examples of pharmaceutically acceptable base addition salts include sodium, potassium, calcium, ammonium, organic amino, or magnesium salts, or the like. When compounds contain relatively basic functionalities, salts can be obtained by addition of the desired acid, either neat or in a suitable inert solvent. Examples of pharmaceutically acceptable acid addition salts include those derived from inorganic acids like hydrochloric, hydrobromic, nitric, carbonic, monohydrogencarbonic, phosphoric, monohydrogenphosphoric, dihydrogenphosphoric, sulfuric, monohydrogensulfuric, hydriodic, or phosphorous acids and the like, as well as the salts derived from relatively nontoxic organic acids like acetic, propionic, isobutyric, maleic, malonic, benzoic, succinic, suberic, fumaric, lactic, mandelic, phthalic, benzenesulfonic, p-tolylsulfonic, citric, tartaric, methanesulfonic, and the like. Also included are salts of amino acids such as arginate and the like, and salts of organic acids like glucuronic or galacturonic acids and the like.
[0245] The neutral forms of the compounds may be regenerated by contacting the salt with a base or acid, and isolating the parent compound in the conventional manner. The parent form of the compound differs from the various salt forms in certain physical properties, such as solubility in polar solvents, but otherwise the salts are equivalent to the parent form of the compound for the purposes of this invention.
[0246] In addition to salt forms, this invention provides compounds which are in a prodrug form. Prodrugs of the compounds described herein are those compounds that readily undergo chemical changes under physiological conditions to provide the compounds of the present invention. Additionally, prodrugs can be converted to the compounds of the present invention by chemical or biochemical methods in an ex vivo environment. For example, prodrugs can be slowly converted to the compounds of the present invention when placed in a transdermal patch reservoir with a suitable enzyme or chemical reagent. Prodrugs are often useful because, in some situations, they may be easier to administer than the parent drug. They may, for instance, be more bioavailable by oral administration than the parent drug. The prodrug may also have improved solubility in pharmacological compositions over the parent drug. A wide variety of prodrug derivatives are known in the art, such as those that rely on hydrolytic cleavage or oxidative activation of the prodrug. An example, without limitation, of a prodrug would be a compound of the present invention which is administered as an ester (the prodrug), but then is metabolically hydrolyzed to the carboxylic acid, the active entity.
[0247] Certain compounds of the invention can exist in unsolvated forms as well as solvated forms, including hydrated forms. In general, the solvated forms are equivalent to unsolvated forms and are intended to be encompassed within the scope of the present invention. Certain compounds of the invention may exist in multiple crystalline or amorphous forms. In general, all physical forms are equivalent for the uses contemplated by the present invention and are intended to be within the scope of the invention.
[0248] Some of the subject compounds possess asymmetric carbon atoms (optical centers) or double bonds; the racemates, diastereomers, geometric isomers and individual isomers are all intended to be encompassed within the scope of the present invention.
[0249] The compounds are generally administered in a therapeutically effective amount, i.e. the amount of the subject compound that will elicit the biological or medical response of a tissue, system, animal or human that is being sought by the researcher, veterinarian, medical doctor or other clinician. The term therapeutically effective amount includes that amount of a compound that, when administered, is sufficient to prevent development of, or alleviate to some extent, one or more of the symptoms of the condition or disorder being treated. The therapeutically effective amount will vary depending on the compound, the disease and its severity and the age, weight, etc., of the mammal to be treated.
[0250] The contacting is generally effected by administering to the subject an effective amount of one or more compounds having a formula herein, including the various embodiments described above. Generally administration is adjusted to achieve a therapeutic dosage of about 0.1 to 50, preferably 0.5 to 10, more preferably 1 to 10 mg/kg, though optimal dosages are compound specific, and generally empirically determined for each compound.
[0251] The term unit dosage forms refers to physically discrete units suitable as unitary dosages for human subjects and other mammals, each unit containing a predetermined quantity of active material calculated to produce the desired therapeutic effect, in association with a suitable pharmaceutical excipient. Typical unit dosage forms include prefilled, premeasured ampules or syringes of the liquid compositions or pills, tablets, capsules, lozenges or the like in the case of solid compositions. In such compositions, the mimetic is usually a minor component (from about 0.1 to about 50% by weight or preferably from about 1 to about 40% by weight) with the remainder being various vehicles or carriers and processing aids helpful for forming the desired dosing form. Unit dosage formulations are preferably about of 5, 10, 25, 50, 100, 250, 500, or 1,000 mg per unit. In a particular embodiment, unit dosage forms are packaged in a multipack adapted for sequential use, such as blisterpack comprising sheets of at least 6, 9 or 12 unit dosage forms.
Examples: Development of Dibenzothiazepinones and Dibenzazepinones as Anti-Cancer Agents
[0252] As part of a phenotypic screen, we identified a small molecule, a dibenzothiazepinone termed MM017, with toxicity to colorectal cancer cells. Using forward genetics, we showed that mutations in Nuclear Valosin Like 2 (NVL2) lead to 30-fold resistance to MM017. NVL2 is an asymmetric, hexameric AAA-ATPase protein that couples ATP hydrolysis to the removal of WDR74 and its chaperone complex from the nascent 60S ribosome, a required step for 60S biogenesis. Using photo-chemistry and structural biology, we demonstrated that these mutations map to and are important for compound binding. Most of the studies involving NVL2 have been performed in yeast, so we developed a NVL2 degron system to investigate its function in colorectal cancer cells. Degradation of NVL2 led to reduced 60S ribogenesis as measured on polysome profiling consistent with its reported function in yeast. Moreover, MM017 phenocopied the effects of NVL2 degradation consistent with the hypothesis that binding leads to inhibition. Critically, cells harboring binding site mutations showed none of these effects confirming that they were on-target (due to NVL2 binding). We subjected MM017 to a PRISM analysis that involves evaluating potency and efficacy for 902 unique and deeply annotated cell lines. The selectivity of MM017 across these cell lines was most highly correlated (among 1,215 compounds) with oxaliplatin and carmofur. Carmofur is a 5-Flurouracil prodrug that is approved for the treatment of colorectal cancer in Japan and has also been shown to block 60S ribosome biogenesis. These correlations provide independent evidence that oxaliplatin and carmofur are toxic by blocking ribosome biogenesis. In addition, the utility of these drugs in CRC supports the rationale for testing MM017 in models of CRC. From here we developed analogs of MM017 that are optimized for in vivo proof-of-concept studies to assess tolerability, efficacy and pharmacodynamic markers for NVL2-targeting ribosome biogenesis inhibitors. We developed an optimization screening funnel that includes p53/p21 upregulation, known markers of impaired ribosome biogenesis-induced stress, as an on-target pharmacodynamic marker.
[0253] Targeting NVL2 provides a translatable strategy for colorectal cancer chemotherapy via a first-in-class alternative mechanism of ribosome biogenesis inhibition compared to clinically used ribotoxic drugs with undefined molecular targets. We disclose (1) design, synthesis, and evaluation of a collection of benzothiazepine-based NVL2 inhibitors to select a candidate suitable for in vivo evaluation, and (2) evaluation of in vivo drug tolerability, pharmacodynamics, and efficacy of optimized NVL inhibitors in a colorectal cancer xenograft model. Innovations include the first and only known small molecule to inhibit NVL2; compound resistant mutations to delineate on and off-target effects in cells; compound resistant xenografts derived from resistant cell lines above to delineate on and off-target pharmacodynamics and efficacy in vivo; and germline compound resistant NVL2.sup.R403W/+ knock-in mice to delineate on and off target toxicity in mice.
Results I
[0254] We performed a high throughput screen of 99,599 small molecules (UTSW chemical library) for compounds that inhibit the proliferation of HCT116 colorectal cancer cells. A major challenge in phenotypic screening is understanding the mechanism of action often referred to as target ID. To address this challenge, we developed an isogenic, inducible forward genetic system that reveals compound resistant mutations.
[0255] As part of this effort, we identified MM017 as a novel small molecule with anti-proliferative activity in HCT116 cells. In total, we isolated 61 HCT116 resistant clones, and 11 of these were subject to whole exome sequencing, which revealed recurrent mutations in Nuclear Valosin Like 2 (NVL2). Follow-up NVL2-focused sequencing studies revealed that all 61 clones harbored mutations in NVL2. NVL2 is a AAA-ATPase protein that in yeast is responsible for removing (or unfolding) the NSA1 module, a set of chaperones bound to a nascent 60S ribosomal subunit in the nucleolus. As a result, NVL2 is essential for the biogenesis of the 60S ribosome. NVL2 consists of an N-terminal domain (NTD) important for localization to the nucleolus, and two tandem ATPase domains. The mutations that lead to resistance cluster in discrete regions of the first ATPase domain implicating this domain in the mechanism of action. We also CRISPR edited this exact mutation into a nave cell and observed compound resistance.
[0256] To test whether NVL2 mutations prevent compound binding, we synthesized MM0514, a crosslinker derivative of MM017. MM0514 contains an aryl azide, and thus is capable of covalently modifying target proteins following exposure to UV light. MM0514 also contains an alkyne group providing a handle to purify bound proteins using click chemistry. Critically, MM0514 retains on-target activity to HCT116 cells since NVL2.sup.R403W mutant cells are resistant. We crosslinked either parental or NVL2.sup.R403W HCT116 cells to MM0514 and analyzed NVL2 binding. In a dose dependent manner, NVL2 bound MM0514 in parental cells but to a lesser degree in NVL2 mutant cells. These observations demonstrate that mutations in NVL2 confer resistance by preventing the direct binding of MM017 derivatives. Taken together, these results confirm that the anti-proliferative impact of MM017 and its derivatives is through binding NVL2. To characterize the binding site, we solved the cryo-EM structure of NVL2 with MM017. MM017 binds to a single site in the asymmetric hexamer near the D subunit. Consistent with our binding data, the mutations map near the binding site, including R403, which is mutated to tryptophan in a resistant clone and predicted to prevent binding of MM017 or related analogs. The cryo-EM structure of NVL2 with MM017 provides further evidence of target identification and also a tool for optimizing a bioavailable compound.
[0257] NVL2 in yeast is essential for 60S ribosomal maturation, and therefore, we hypothesized that MM017 might decrease 60S ribosome synthesis. To test this hypothesis, we subjected either parental or NVL mutant cells treated with MM017 for different time points to polysome profiling. Polysome profiling uses a sucrose gradient to fractionate the complete ribosome (80S) from its components, the large (60S) and small (40S) subunit. Parental cells treated with MM017 revealed a time-dependent decrease in the 60S and 80S ribosomal subunits, consistent with reduced 60S biogenesis. Since the 80S is a complex of the 40S and 60S ribosomes, fewer 60S ribosomes are expected to result in increased free 40S subunits. All of these changes are the result of binding NVL2 since they were not present in the NVL2.sup.R403W mutant cells. Taken together, these observations indicate that MM017 inhibits NVL2 leading to reduced 60S ribosome.
[0258] Inhibition of 60S ribosome biogenesis is known to induce the stability and upregulation of p53, which could serve as a potential pharmacodynamics marker for MM017 in HCT116 cells. Consistently, MM017 upregulates p53 levels in parental HCT116 cells but not NVL2.sup.R403W mutant cells. We used PRISM (Broad Institute) to evaluate the selectivity of MM017 across 902 cancer cell lines and then correlated this selectivity to 1,215 clinical and pre-clinical compounds in the PRISM database. The selectivity of carmofur (r=0.53, adjusted p<10.sup.30) and oxaliplatin (r=0.5, adjusted p<10.sup.30) significantly correlated with MM017 suggesting that all three compounds have a similar mode of action. These observations indicate that oxaliplatin and carmofur, like MM017, target ribosome biogenesis.
Results II
[0259] We describe above a benzothiazepine small molecule that binds the ribosome biogenesis factor NVL2 and kills colorectal cancer cells in a dose-dependent manner that correlates with the upregulation of p53, a downstream effect of ribosome biogenesis inhibition. There are currently no known NVL2 inhibitors and therefore, this novel class of benzothiazepine-based NVL2 inhibitors provides reagents for medicinal chemistry optimization towards in vivo active lead compounds for proof-of-concept evaluation in colorectal cancer xenograft models.
Medicinal Chemistry Optimization of Dibenzothiazepinone- and Dibenzazepinone-Based NVL2 Inhibitors.
[0260] Design and synthesis of benzothiazepine-based NVL inhibitors. We demonstrated that the dibenzothiazepinone scaffold is amenable to medicinal chemistry optimization such that we can synthesize analogs with desirable drug-like properties. We synthesized a large collection of dibenzothiazepinone and dibenzazepinone analogs and revealed its structure activity profile. Analogs were evaluated against the colorectal cancer cell line HCT116, and counter-screened against a compound resistant NVL2.sup.R403W clone. Cytotoxicity in wild-type HCT116 was determined. All active analogs displayed on-target cytotoxic activity and were between 10 to 100-fold less potent against an NVL2.sup.R403W clone. Initial SAR focused on exploring the replacement of the furan ring of initial dibenzothiazepinone hit MM017. We first explored a wide variety of mono- and di-substituted phenyl rings, including a broad spectrum of functionality (F, Cl, alkyl, alkoxy, fluoroalkoxy, CN, formamide, S(O) Me, carboxyl, . . . ). Ortho-substituents were not allowed, except for fluorine and only 3- or 4-substituted, or 3,4-disubstituted phenyl analogs retained activity similar to the parent. Five-membered heterocycles other than furan significantly reduced potency, whereas benzoxazole, benzothiazole, and 2-oxo-2,3-dihydrobenzoxazoles were equipotent or somewhat more potent than the corresponding phenyl analogs. We also found that several amides derived from non-aromatic acyclic or mono- or spirocyclic carboxylic acids led to active analogs. Because of potential protease mediated cleavage of the amide bond, we investigated replacement of the amide linker (C(O)NH and found that ureas retained similar potency, as did thioamides and thioureas. Reverse amides and sulfonamides on the other hand were inactive. Moving to the side-chain, we found that a longer propargyloxy or hexenyl boosted potency 3 to 10-fold, but at a cost of increased lipophilicity and number of rotatable bonds. A shorter rigid 2-butynyl proved optimal and increased activity >10 to 20-fold.
[0261] SAR data correlated with insights gained from co-CryoEM NVL2 structures with several dibenzothiazepinones and dibenzazepinones. This led us to design a series of heteroaromatic analogs where we replaced the amide-linked dibenzothiazepinones or dibenzazepinones with amine-linked dibenzothiazepinones and dibenzazepinones. A variety of aromatic, heteroaromatic, heterocyclic, carbocyclic, and acyclic groups linked to the dibenzothiazepinone or dibenzazepinone core via an amine linkage were found to retain or improve activity.
[0262] With input from our current SAR data, we designed and synthesized new analogs based on the generic scaffold. We retain the more potent and less lipophilic alkynyl side-chain while also exploring additional rigidification, metabolic blocks, and truncation. We found that oxidation of the central dibenzothiazepinone sulfur atom (to SO or SO.sub.2), or replacement with an oxygen atom, was not tolerated, but CH.sub.2 substitution reduced activity only 2 fold. Based on this finding, we also replaced the central sulfur atom with a CHMe unit and found these to retain similar activity as the sulfur analogs. Replacement with a CHCN or CMe (OH) unit reduced activity somewhat. Therefore, our subsequent designs retain a central sulfur or (optionally substituted) carbon atom. We next explored substituents on the various positions available on the two benzo-rings of the central dibenzothiazepinone core. We found that fluorine, chlorine, and cyano substituents were allowed in the right-hand benzo-ring, retaining full potency if introduced in the two positions not directly adjacent to the benzo-fusion. No such substitutions were allowed in the left-hand benzo-ring. We also sampled analogs where we replaced individual CH-units of the two benzo-rings with nitrogen (pyrido analogs). These were not allowed in the right-hand benzo-ring, whereas they were allowed in the left-hand ring at positions marked U and W in the generic structures of the claims. We further found that replacement of a CH with a nitrogen at position W in the generic structures significantly increased the metabolic stability of the analogs when measured in a microsomal stability assay. All of the central dibenzothiazepinone and dibenzazepinone core scaffolds can be synthesized from readily available starting materials using the same chemistry, herein. We focus on substituents that are small, improve physicochemical properties, and reduce metabolism. The final step of the synthesis involves conjugation of the peripheral units (R3 in the generic structures) with an amino-substituted central core via Pd-catalyzed CN bond formation (structures of formula VI) or reductive amination, or amide-bond formation with appropriate carboxylic acids (structures of formula VII). Thioamides (structures of formula VIII) are derived from reacting the amino-dibenzothiazepinone core with R.sup.3-aldehydes and sulfur powder in aqueous K.sub.2CO.sub.3. Ureas (structures of formula II or IV) and thioureas (structures of formula III or V) are obtained from the same amino-substituted central cores using contemporary methods of urea/thiourea formation using triphosgene or thiophosgene. Preferred substitutions only incorporate druglike substituents or groups with desirable physicochemical properties, and limited predicted metabolic liabilities. Preferred substituents are small, improve physicochemical properties, and reduce metabolism.
[0263] Our nextgen analogs retain or improve C Log P and conform to druglike space with zero Lipinski Rule of 5 or Veber rule violations. Introducing sp.sup.3-stereocentra could be beneficial for activity and specificity, solubility, and reduced protein binding.
[0264] Assessing the ability of NVL2 inhibitors to selectively kill WT versus NVL2.sup.mut HCT116, block ribosome biogenesis and induce p53. We evaluate analogs in the colorectal cancer cell line HCT116 and already available compound-resistant clones. One clone has a mutation in the compound binding site (NVL2.sup.R403W) and another clone (NVL2.sup.P307T) has a mutation distant from the binding site that confers resistance through an unknown effect. Based on our results, analogs that kill HCT116 cells via NVL2 inhibition (on-target) have reduced potency in compound-resistant HCT116 mutant clones. Our analogs have been counter-screened against the NVL2 compound-resistant mutant clones with fold resistance range between 10-100 fold (most analogs 20-50 fold). This counter screen provides a strategy for identifying off-target toxins. Analogs that dose-responsively kill wild-type cancer cells with an IC.sub.50<1,000 nM and are at least 20-fold less potent in NVL mutant cell lines are progressed.
[0265] Analogs that pass potency and on-target NVL2 inhibition criteria and are metabolically stable (T.sub.1/2>30 min in microsomal assays) are further evaluated for their ability to inhibit ribosome biogenesis (polysome profiling, and induction of p53 and/or p21). Antibodies for p53 are used to evaluate p53 as a pharmacodynamic marker for in vivo studies.
[0266] Profiling of analogs for in vitro metabolism, plasma stability, solubility, and plasma protein binding. We evaluated the majority of analogs for oxidative metabolism using murine microsomal fractions in the presence of an NADPH regenerating system necessary for phase I metabolism. Half-lives are determined by the method of substrate depletion. Compounds identified as having significant metabolic liabilities (T.sub.1/2<30 min) have high in vivo clearance rates and were not pursued further. Methoxy substituents are potentially labile to oxidative metabolism and therefore, introducing fluorine metabolic blocks were explored as well. Because we suspected that some metabolic clearance might be protease mediated, selected analogs were evaluated in microsomal fractions in the absence of an NADPH regenerating system to eliminate phase I oxidative metabolism. We found that some amides still metabolized at an appreciable rate, whereas others were more stable. Unsurprisingly, amines, ureas, and thioureas were stable under these conditions (T.sub.1/2>120 min).
[0267] Compounds with acceptable metabolic clearance rates are evaluated in additional in vitro assays including aqueous solubility, plasma stability and protein binding using the gold-standard rapid equilibrium dialysis. Current SAR indicates that we can achieve high activity, solubility, and acceptable metabolic stability with more polar compounds (C Log P<4).
[0268] Pharmacokinetic studies of NVL2 inhibitors. For pharmacokinetic evaluation we measure the exposure of analogs after iv (3 or 5 mg/kg), ip (10 mg/kg) and oral (20 mg/kg) dosing. Drug levels in plasma and liver are measured (LC-MS/MS) at eight time points (3 mice/time point). Total plasma or tissue exposure (AUC) and half-lives are calculated using the non compartmental analysis tool of WinNonlin. Oral bioavailability is calculated as AUCoral/AUCivDoseiv/Doseoral (desired criteria F>30%). The most promising compound are dose escalated for up to 3 dose levels to determine whether increased exposure occurs with increased dose. Whereas initial PK is done in female CDI mice, dose escalation is evaluated in both females and males.
[0269] For in vivo studies we prefer orally available compounds, but intraperitoneal (ip) or intravenous (iv) delivery is deemed acceptable for proof-of-concept studies. We select for compounds with a terminal half-life of >2 hours and [Cmax].sub.u>IC.sub.90 (cellular tox in HCT116).
In Vivo Tolerability, Pharmacodynamics, and Efficacy of NVL2 Inhibitors.
[0270] The NVL2 ATPase is required for biogenesis of the 60S ribosome. Preliminary data including cryo-EM structures demonstrates that dibenzothiazepinones and dibenzazepinones bind directly to NVL2 which results in decreases of the 60S and 80S ribosomes, an upregulation of p53, and cell death. The cytotoxic effects of dibenzothiazepinones and dibenzazepinones are consistent with the hypothesis that they selectively target cancers dependent on increased ribosome biogenesis. Oxaliplatin, an effective treatment for colorectal cancer, inhibits ribosome biogenesis through an unknown mechanism. This indicates that dibenzothiazepinones and dibenzazepinones might have efficacy in colorectal cancer. We test this hypothesis by systematically evaluating the antitumor capacity of optimized dibenzothiazepinone and dibenzazepinone analogs in pre-clinical models of colorectal cancer. We also evaluate whether these effects are mediated via inhibition of ribosome biogenesis and upregulation of p53 and determine if there are on-target toxicities resulting from NVL2 inhibition in healthy, non-tumor bearing tissues. We define the tolerability, pharmacodynamic response, and single-agent efficacy against wild-type and compound resistant colorectal cancer xenografts of lead bioavailable NVL2 inhibitors.
[0271] Tolerability of dibenzothiazepinone or dibenzazepinone treatment in mice and determine whether toxicities are caused by engaging NVL2. We test the tolerability of chronic, once-daily oral or intravenous treatment (route of administration depending on PK parameters) with doses of dibenzothiazepinone or dibenzazepinone analogs. Three doses are chosen for evaluation in tolerability studies based on the specific PK data and solubility characteristics of each analog. C57Bl/6 mice are randomized to four treatment cohorts per analog (n=5 male and 5 female mice per arm: 1 vehicle, 1 low dose benzothiazepine, 1 intermediate dose benzothiazepine, 1 high dose benzothiazepine). Vehicle and drug treatments are administered once daily via oral gavage (or intravenous tail vain injection) for 14 consecutive days. Primary endpoints for the study are body weight changes and hematologic, renal, and hepatic toxicity. Secondary endpoints are absolute benzothiazepine concentration in plasma. Exploratory endpoints are other standard parameters measured by Complete Blood Counts (CBCs) and serum chemistry analyses. At the end of the 14-day treatment period, we anesthetize mice, collect blood samples via cardiac puncture, and euthanize the animals. Blood samples are evaluated for CBCs and serum chemistry analyses.
[0272] Body weight changes provide a metric of gross toxicity. The toxicity threshold for weight changes was selected as a 20% decrease relative to vehicle-treated mice. Mice that reach this threshold are humanely euthanized. CBCs are used to assess hematologic toxicity. Low platelet counts (<772K/L) or hemoglobin levels (<13 g/dL) are used to detect drug-induced thrombocytopenia or anemia. Serum chemistry data are used to assess renal and hepatic toxicity. Elevated creatinine levels (>1.5 mg/dL) serve as a marker of kidney dysfunction. Elevated alanine aminotransferase (ALT) (>346.5 U/L) or aspartate aminotransferase (AST) (>690 U/L) levels indicate liver damage. Threshold values for plasma and serum biomarkers of toxicity were derived by applying Grade 1 adverse event thresholds (Common Terminology Criteria for Adverse Events Version 5.0 published by the NCI) to 95% confidence interval limits for these biomarkers in nave mice. The MTD is determined for each benzothiazepine analog as the highest dose that can be administered daily for 14 consecutive days without causing average levels of toxicity biomarkers in the cohort to exceed the thresholds defined above. Satellite PK measurements of compound levels in plasma are made to confirm bioavailability.
[0273] To interrogate off target versus on target toxicities, we generated knock-in mice harboring a germline compound resistant NVL2.sup.R403W mutation. Heterozygous knock-in mice are generated in the C57BI/6 background using CRISPR/Cas9 and can be bred to homozygosity. Next, we treat WT and NVL2.sup.R403W mice with vehicle control or three different doses of dibenzothiazepinone or dibenzazepinone analogs (n=5 mice/group/genotype). Mice are age matched and gender matched (1 gender/group unless toxicity differences between male and female mice were observed) and analyzed using the same endpoints described above. Doses are selected based on determination of the MTD and include at least one dose below and one dose above the MTD. For analogs with greater toxicity in WT mice as compared to NVL2.sup.R403W mice, that would suggest on-target effects caused by NVL2 engagement by dibenzothiazepinone or dibenzazepinone analogs. To confirm, we compare levels of ribosome biogenesis and p53 induction in compromised tissues or cell types in WT and NVL2.sup.R403W mutant mice. For analogs that are toxic in germline NVL mutant mice, we conclude that these effects are caused by off-target effects. In case of on-target mediated toxicities, we then define if there is a therapeutic window available where side-effects can be minimized while retaining antitumor efficacy. In case of off-target effects, we will attempt to determine the offending mechanism and implement appropriate assays in our medicinal chemistry pipeline to identify analogs with reduced off-target toxicity.
[0274] Evaluate pharmacodynamic effects of dibenzothiazepinone and dibenzazepinone analogs and identify candidate biomarkers for in vivo target engagement. Our in vitro data demonstrate that dibenzothiazepinones and dibenzazepinones kill cancer cells via direct inhibition of NVL2. We also demonstrated that NVL2 inhibition with dibenzothiazepinones or dibenzazepinones impairs biogenesis of the 60S ribosomal subunit, leading to upregulation of p53. Similar experiments with isogenic dibenzothiazepinone-resistant NVL2.sup.R403W knock-in clones do not show inhibition of ribosomal biogenesis, upregulation of p53, or antiproliferative activity when treated with NVL2-targeting dibenzothiazepinones or dibenzazepinones. Therefore, we evaluate p53 upregulation as a viable PD marker for on-target activity. In addition, we assess xenografts for decreases in ribosome biogenesis and activation of molecules downstream of p53, such as p21.
[0275] To test whether dibenzothiazepinone or dibenzazepinone analog treatment induces p53 and blocks ribosome biogenesis in vivo, ICR SCID mice are transplanted subcutaneously with 510.sup.6 WT or NVL2.sup.R403W HCT116 colorectal cancer cells. Xenografts are formed from the population of HCT116 cells targeted with guides for the NVL2.sup.R403W knock-in mutation to eliminate potential artifacts that may arise within a single clone that has incurred off-target mutations. Once tumors reach 110 mm.sup.3, mice are randomized to vehicle and dibenzothiazepinone or dibenzazepinone treatment arms (n=8 mice per arm; 16 mice total/genotype). NVL inhibitors or vehicle control are administered at the MTD once daily via oral gavage, intraperitoneal, or intravenous tail vain injection for 3 days. On Day 3, we collect blood samples and euthanize mice to harvest liver and xenografts to assess PK (in blood, liver and tumor) and PD markers (in tumor). To nominate candidate biomarkers, tumor tissues collected from control or compound-treated mice are compared by quantitative Western blot analysis of p53, as well as downstream induction of p21 via qPCR.
[0276] Determine the efficacy of dibenzothiazepinones and dibenzazepinones in xenograft models of colorectal cancer and validate candidate biomarkers. After evaluating tolerability and PD, we use wild type and NVL2.sup.R403W HCT116 xenograft models to assess the antitumor activity of analogs in vivo. We transplant wild type and NVL.sup.R403W HCT116 cells subcutaneously and begin treatment. NVL inhibitor analogs are given at the MTD once daily via oral gavage, intraperitoneal, or intravenously via tail vain injection (frequency and route of administration to be determined based on PK). Treatments continue until mice display symptoms of tumor burden that necessitate euthanasia or until 50 days post-randomization, whichever occurs first. We collect remaining tumor tissues as available for PD analysis. The primary endpoint is overall survival. We construct Kaplan Meier curves for each benzothiazepine analog in each xenograft model. Log-rank tests are used to statistically evaluate differences in survival between drug- and vehicle-treated cohorts. In addition, we measure tumor volumes every 3 days and graph tumor growth over time which serve as a complementary endpoint.
[0277] Next, we perform a dose response efficacy study by establishing wild-type HCT116 xenografts and administering NVL inhibitor analogs as described above. The top dose is the MTD and two additional lower doses are chosen by referring to PK data (n=8 mice per arm3 doses and vehicle control; n=32 mice total). Tumor growth over time and survival is quantified as described and remaining tumor tissues are collected as available for PD analysis. The lowest dose with statistically equivalent efficacy to that achieved with the MTD is determined.
[0278] Finally, p53 and p21 levels are reassessed in tumor tissues treated at the lowest efficacious dose for 3 days in a separate PD cohort (n=5/arm; vehicle control and 1 dose for 10 mice total). For example, we quantify the difference p53 and p21 levels to determine the magnitude of the change in the biomarker induced by a therapeutic dose of benzothiazepine.
[0279] We define the therapeutic window for each dibenzothiazepinone or dibenzazepinone analog by identifying doses that are well tolerated and induce robust tumor PD responses and efficacy in colorectal xenograft models. p53 induction observed in benzothiazepine treated tumors is mitigated in xenografts formed from NVL.sup.R403W cancer cells, thereby confirming the mechanism of action in vivo. The levels of p53 induction positively correlate with the degree of dibenzothiazepinone or dibenzazepinone antitumor efficacy in a dose dependent manner.
Examples: Optimized Dibenzothiazepinone and Dibenzazepinone Chemicals Inhibit NVL-Mediated Ribosome Assembly and Cause p53-Dependent Apoptosis of Cancer Cell Xenografts
[0280] In these examples we identify human NVL as the target of a chemical toxin designated, MM017. A cryo-EM structure of NVL bound to MM017 reveals binding sites within the hexameric assembly. Mutations in NVL that cause resistance to MM017 cluster in the binding site and lead to a reduction in compound binding. The NVL-MM017 interaction specifically inhibits the maturation of 60S ribosomal subunits, causing abnormal polysome profiles and accumulation of newly synthesized pre-60S intermediates in the nucleolus. NVL inhibition triggers p53-mediated apoptosis without any evidence of DNA damage. A bioavailable analog of MM017 reduces tumor growth in vivo without overt toxicity.
Mutations in NVL Confer Resistance to Orphan Cytotoxin MM017.
[0281] We recently described an isogenic forward genetic system to rapidly find mutations conferring resistance to compounds with anti-proliferative activity (32). This system uses an engineered colorectal cancer HCT116 cell line (iHCT116) in which the addition of indole acetic acid (IAA) initiates a ubiquitin-mediated degradation of the DNA mismatch repair protein MLH1, thereby providing a mechanism to temporarily increase mutation rates. We applied this strategy to MM017, a dibenzothiazepinone identified in a high-throughput small molecule screen for HCT116 cytotoxicity. MM017 inhibits the growth of iHCT116 cells in a dose-dependent manner, with an IC50 of 0.46 M. We exposed barcoded iHCT116 cells, that had previously been cultured either with (Mutagenesis-on) or without IAA (Mutagenesis-off), to increasingly lethal doses of MM017. The total number of surviving clones was dramatically higher in the Mutagenesis-on conditions and increased in a dose-dependent manner suggesting a genetic basis for resistance.
[0282] We identified 59 clones with unique barcode sequences, which indicates that each clone arose from a unique founder event. The IC50 of MM017 to these clones was between 2.45 to 32.89-fold greater than the parental cell line providing evidence of resistance. The wide degree of resistance suggests that these clones harbored a diverse set of mutations, and therefore, we performed whole exome sequencing on 15 clones spanning the entire range of resistance. From whole exome sequencing, we identified variants that were acquired during IAA-induced mutagenesis with the hypothesis that genes related to resistance will be mutated in multiple clones. Two genes contained acquired variants in at least 3 of the 15 selected clones: TERT, mutated in 3 of 15 clones, and NVL, mutated in all 15 clones. These results suggest that NVL mutations are related to MM017 resistance. Thus, for the remaining clones, we performed PCR based sequencing of NIL exons that were found to be mutated in the exome sequencing data. In sum, 57 out of 59 unique clones harbored NVL mutations. The majority of mutations clustered within the D1 AAA+ ATPase domain and frequently affecting the same codons. To test whether these mutations are sufficient for MM017 resistance, we used CRISPR-Cas9 to knock-in two of the most resistant mutations (NVL.sup.P307T, NVL.sup.R403W) and a mutation with intermediate resistance (NVL.sup.H304R). Transfection of cells with sgRNAs targeting these NVL residues in addition to a mutation-encoding repair template yielded an increased rate of resistance when compared to mock treatments. Following expansion, we confirmed that cells harbored the intended alleles (NVL.sup.P307T, NVL.sup.R403W or NVL.sup.H304R) and were more resistant to MM017 compared to NVL.sup.WT, (IC50: NVL.sup.WT=0.38 M; NVL.sup.R403W>50 M; NVL.sup.P307T>50 M; NVL.sup.H304R=2.4 M), but equally sensitive to an unrelated toxin, paclitaxel. Taken together, these observations demonstrate that NVL mutations are specific and sufficient for MM017 resistance.
MM017 Directly Binds NVL.
[0283] To assess whether MM017 binds directly to NVL in cells, we used a MM017 crosslinker (Probe compound (2), Table A) that is UV-activatable and contains an alkyne that can be coupled to biotin for affinity purification. Critically, Probe compound 2 inhibited the proliferation of HCT116 cells (IC50=0.47 M) with a potency comparable to MM017, and NVL.sup.P307T cells were comparatively resistant to both compounds, suggesting that MM017 and MM017-probe function similarly. We purified MM017-probe bound proteins from cells that had been treated with varying doses of MM017-probe either in the presence or absence of UV light. NVL was only detected in conditions that included both the MM017-probe and UV light, indicating that MM017-probe interacts non-covalently with NVL in the absence of UV light. To assess whether the observed binding of MM017-probe to NVL is relevant to its cellular activity, we performed probe-displacement assays using three chemically related derivatives of MM017 (compounds 3-5, Table A) with IC50s of 0.36 M (3), 2.1 M (4) and 13 M (5). Note, this experiment was performed using a cell line in which we knocked-in a FLAG epitope into the C-terminal end of NVL. Co-incubation of increasing doses of compound 3 more effectively displaced MM017-probe compared to compounds 4 and 5, establishing a relationship between NVL binding and cellular activity. We next compared NVL levels following MM017-probe and UV treatment of NVL.sup.WT versus NVL.sup.R403W, NVL.sup.P307T, and NVL.sup.H304R cell lines. In comparison to NVL.sup.WT, the amount of MM017-probe required to crosslink NVL was substantially higher in the mutant cell lines demonstrating that these mutations affect compound binding. All together these observations establish a relationship between compound binding and cellular activity that is consistent with the hypothesis that NVL is the direct target of MM017.

Cryo-EM Reconstruction of the NVL/MM017 Complex.
[0284] To understand the molecular basis of the MM017/NVL interaction, we set out to solve the cryo-EM structure of NVL in complex with MM017. Expressing and purifying the D1/D2 core of wildtype NVL led to low yields and protein instability. Cryo-EM analysis showed that wildtype NVL D1/D2 assembled into long, filament-like spirals rather than the expected hexamers. Double mutations in the Walker B motif of the C. thermophilum NVL homolog Rix7 stabilize the hexameric configuration (33), and recombinant expression and purification of mutated human NVL.sup.E366Q/E683Q (NVL.sup.dEQ) similarly resulted in stable, monodisperse hexamers, whose stoichiometry was unaffected by the addition of MM017 as determined by mass photometry.
[0285] A single particle cryo-EM reconstruction of NVL.sup.dEQ+MM017 resulted in a map with an overall resolution of 2.9 . Similar to reconstructions of C. thermophilum Rix7, H. sapiens P97 and S. cerevisiae Drg1, the NVL hexamer forms a staircase configuration, with pore loops from five D1 and D2 AAA+ modules engaging an extended peptide within the central channel (2, 27, 34, 35). Following convention, we designate the topmost staircase subunit A and the lowest subunit E. As previously observed, the sixth subunit (F) is in a more dynamic state, transitioning between positions E and A, and is therefore poorly resolved in the cryo-EM map. By analogy to the analysis performed with RIX7 (34) and the bulky nature of sidechain density within the peptide, we hypothesize that the substrate mimic engaged by NVL represents one of the N-terminal 14x-HIS tag on our construct and have therefore modeled it as a poly-histidine chain, even though our tag also includes non-HIS linker residues.
[0286] An initial analysis of the cryo-EM maps revealed additional density consistent with MM017 in a single position within subunit E. MM017 is wedged into a mostly hydrophobic pocket in the core domain of the D1 module. The ligand pocket is walled on one side by the central D1 -sheet (strands 5, 1 and 4) and on the other side by the N-terminal 0 helix and the loop element preceding strand 1. This helix also engages the AAA+ lid-domain of subunit D, which forms the more peripheral boundary of the MM017 binding pocket. There is no ligand binding site in the equivalent regions of NVL subunits A-D because the 0 helix is tightly packed against the central -sheet of the domain, precluding MM017 binding. To determine if MM017 also engaged the poorly resolved and mobile F subunit, we performed a skip-align classification with a mask around the subunit F D1 module. The resulting reconstruction of this particle subset revealed MM017 density in subunit F in the analogous position to subunit E. Most suppressor mutations cluster around the ligand binding pocket, consistent with these modifications altering the structure or conformation of the compound docking site. MM017 is an elongated molecule with a distinct 105 kink introduced by the central dibenzothiazepinone core. The furan ring of MM017 is exposed to the central solvent channel that separates the D1 and D2 ring stacks and makes hydrophobic contacts with residues M280 and V301 and forms a hydrogen bond with R428. Adjacent to the furan moiety, the planar amide linker forms a hydrogen bond with the backbone carbonyl of amino acid P298. The dibenzothiazepinone ring structure of MM017 is in a hydrophobic environment created by residues M280, M284, P297, L324, R403 and L405. Among these, M284, P297, R403 and L405 are either mutated or immediately adjacent to a mutated residue in our suppressor dataset. In addition, the central carbonyl group is within hydrogen bonding distance of the epsilon-amino group of R403. Finally, the methoxyethyl tail projects out near the loop connecting helix 0 and strand 1.
[0287] To gain further insights on how substrate binding may affect the inter-subunit dynamics of NVL, we obtained single particle cryo-EM reconstructions of apo-NVL.sup.dEQ to a resolution of 2.6 . In the apo structure, the hexameric assembly retains the staircase conformation, but the ligand binding pocket in subunit E is closed and in the same configuration as the equivalent positions within subunits A-D. In the apo structure, the subunit E D1 domain shifts closer to the neighboring AAA+ module in subunit D, closing the bipartite nucleotide binding site at the D/E interface and bringing the arginine finger motif of subunit E into closer proximity to the bound ATP in comparison to the MM017-engaged structure of NVL, suggesting that compound binding allosterically affects the D/E interface within the D1 ring. Consistent with this, one of the most resistant NVL mutations, P307T, maps to the D/E nucleotide interface. We infer that the observed allosteric link between the ligand binding pocket and the nucleotide binding site at the D/E interface hinders the assembly of a functional D1 ring in the presence of MM017.
MM017-Bound NVL Specifically Blocks 60S Biogenesis in the Nucleolus.
[0288] To study the effect of NVL depletion, we engineered a C-terminal FLAG-epitope auxin-inducible degron (AID) tag into NVL in cells that also express the plant E3 ligase TIR1. 5-Phenyl-indole-3-acetic acid (Ph-IAA) treatment caused dose-dependent depletion of NVL-AID but not untagged NVL and in NVL.sup.AID/AID cells, reduced viability in a dose-dependent manner. The viability of NVL.sup.+/+ or NVL.sup.AID/+ cells was unaffected by Ph-IAA, indicating that although NVL is essential for HCT116 cell proliferation, it is not haploinsufficient.
[0289] We next assessed the impact of disrupting NVL on the distribution of ribosomal species using polysome profiling. Addition of Ph-IAA to induce NVL degradation in NVL.sup.AID/AID cells led to a time-dependent reduction in free 60S and 80S levels (based on absorbance at 260 nm) and a concomitant increase in 40S levels. Ph-IAA addition also caused half-mer polysomes, which represent unjoined 40S subunits bound at mRNA initiation sites and are characteristic of a 60S biogenesis defect (36). Addition of MM017 to NVL.sup.WT cells phenocopied the polysome profiles from Ph-IAA-treated NVL.sup.AID/AID cells but caused no changes in polysome profiles from NVL.sup.P307T cells. The polysome profiles following NVL disruption in HCT116 cells appear similar to those reported in yeast with RIX7 mutations (37) or in human cells overexpressing catalytic mutants of NVL (38).
[0290] The observed reduction in free 60S using polysome profiling could be the consequence of decreased 60S synthesis or accelerated 60S degradation, or a combination of the two. To distinguish between existing and newly synthesized 60S, we engineered HCT116 cells to express a C-terminal SNAP-tag on eL36, a ribosomal protein incorporated into the 60S subunit prior to NVL binding (39) or a control C-terminal SNAP-tag on a component of the small ribosomal subunit, eS17, to monitor 40S biogenesis (40). We first labeled existing eL36 or eS17 in cells with an Oregon green benzylguanine (green). Then, we treated cells for 24 hours with either vehicle or MM017 before adding a 647-SiR benzylguanine to label the pool of proteins synthesized over the 24-hour period and evaluated each polysome profile fraction for either existing or new proteins. Existing eL36-SNAP was present in 60S, 80S, and polysome fractions, indicating that the SNAP-tagged protein can assemble into translating ribosomes. MM017 treatment had no impact on the levels or fractionation pattern of existing eL36-SNAP. By contrast, following MM017 treatment, newly synthesized eL36-SNAP was reduced in the 60S, 80S, and polysome fractions, consistent with the hypothesis that MM017 blocks 60S biogenesis. Upon treatment with vehicle or MM017, existing and newly synthesized eS17-SNAP was detected in the 40S, 80S, and polysome fractions, demonstrating that MM017 has no impact on 40S subunits.
[0291] Next, we examined the impact of MM017 on the subcellular localization of eL36-SNAP (60S) or eS17-SNAP (40S). As expected for mature ribosomes, existing eL36-SNAP was nearly completely cytoplasmic, and treatment with MM017 had no impact on its localization. In vehicle treated cells, newly synthesized eL36-SNAP was both nucleolar and cytoplasmic, reflecting its presence in pre-60S and mature ribosomes. By contrast, in cells treated with MM017, new eL36-SNAP localized exclusively to foci within the nucleus. These foci co-localize with the nucleolar protein Fibrillarin, suggesting that the arrested eL36-SNAP intermediates are nucleolar. To test whether the observed block in 60S biogenesis is due to binding to NVL, we engineered cells expressing eL36-SNAP and NVL.sup.R403W. Upon treatment of these cells with MM017, newly synthesized eL36-SNAP localized to the nucleolus and cytoplasm, a pattern indistinguishable from the vehicle treated group. These results demonstrate that the arrest of 60S biogenesis is due to inhibition of NVL by MM017. Finally, we asked whether MM017 impacted either degradation or biogenesis of the 40S ribosome by performing analogous experiments using eS17-SNAP cells. MM017 had no impact on the localization of existing or newly synthesized eS17-SNAP. All together, these results demonstrate that MM017 directly inhibits NVL to specifically block nucleolar 60S assembly.
Inhibition of NVL Leads to p53 Dependent Apoptosis.
[0292] To better understand how inhibition of NVL by MM017 leads to cell death, we performed a genome wide pooled CRISPR/Cas9 knockout screen in HCT116 cells using a library of guide RNAs targeting 19,114 genes. Cells were pulsed intermittently with vehicle or MM017 over 21 days, at which point MM017 treated cells had undergone 9.79 fewer population doublings. Massively parallel sequencing of PCR products amplified from genomic DNA was used to determine relative levels of sgRNA sequences to infer the relative impact of each gene on compound sensitivity. The tumor suppressor TP53 (commonly referred to as p53) and one of its effector genes, CDKN1A (also known as p21), were the most enriched genes in this screen, indicating that loss of p53 and, to a lesser degree, p21 protect cells from MM017. To confirm whether p53 and p21 are required for the anti-proliferative activity of MM017, we performed a growth competition experiment between cells expressing ZsGreen with either p53 or p21 knockout (KO) and control cells expressing mCherry. Without treatment, the ratio between green and red cells was unchanged over time. By contrast, MM017 led to a dose-dependent enrichment of either p53 or p21 KO cells. The requirement for these two proteins was specific to MM017 since no competitive advantage was observed in the presence of paclitaxel. Taken together, these results show that MM017 reduces HCT116 cell proliferation in a p53- and p21-dependent manner.
[0293] To nominate genetic predictors of MM017 sensitivity across different cancer types, we performed a PRISM screen across 902 cancer cell lines with known genotypes (31). A correlation analysis found that mutations in TP53 most significantly linked with resistance to MM017. These findings are consistent with the isogenic CRISPR screen and indicate that p53 is a critical effector for MM017 in cancer cells from multiple lineages and with differing genotypes.
[0294] The essentiality of p53 and p21 to MM017 activity raised the hypothesis that these proteins may be upregulated by inhibition of NVL. MM017 led to an increase in p53 at 6 hours post treatment, and p21 soon thereafter, consistent with its role as a p53 target protein. Importantly, the observed increase in p53 and p21 expression are the result of NVL inhibition because NVL.sup.P307T cells showed no changes in the abundance of either protein, while degradation of NVL in NVL.sup.AID/AID cells led to a similar increase in p53 levels.
[0295] The upregulation of p53 and its effector p21 can arrest cell growth or induce cell death through apoptosis. To distinguish between these two possibilities, we examined cell death by a loss in membrane permeability following a five-day MM017 treatment of HCT116 control and p53 KO cells and found that the number of dead cells was substantially lower in p53 KO cells. The protection from MM017-induced cell death by loss of p53 was specific to MM017, since paclitaxel, an unrelated toxin that stabilizes tubulin polymerization, led to cell death irrespective of p53. Next, we addressed whether cell death was mediated by an apoptotic pathway by assaying for cleaved caspase-3, a bona fide marker of apoptosis. Staurosporine, an unrelated compound that is known to induce apoptosis, led to robust caspase activation in both control and p53 KO cells. By contrast, MM017 induction of cleaved caspase-3 in control cells was substantially reduced in p53 KO cells Taken together, these findings demonstrate that the inhibition of NVL by MM017 leads to p53-dependent apoptosis in HCT116 cells.
[0296] p53 upregulation is consistent with the ribosome assembly stress response triggered by 5S RNP mediated inhibition of MDM2 (5). Other inhibitors of ribosome biogenesis, such as oxaliplatin and CX-5461, are also thought to activate the same ribosome assembly stress response, but these compounds are also known to induce DNA damage (15, 20). A biochemical marker for activation of the DNA damage response is phosphorylation of serine 15 of p53, which results in increased p53 protein (41). Thus, we compared the impact of MM017, oxaliplatin, and CX-5461 on both p53 upregulation and p53 serine 15 phosphorylation. All three compounds led to a dose-dependent increase in the levels of p53, but only oxaliplatin and CX-5461 treatment led to a dose-dependent increase in phosphorylated p53. Even at concentrations as high as 10 M, there was no evidence of serine 15 phosphorylated p53 after MM017 treatment. These observations suggest that p53 upregulation by oxaliplatin and CX-5461 is at least in part triggered by the DNA damage response. Because there was no evidence of serine 15 p53 phosphorylation following treatment with MM017, we conclude that the observed increase in p53 stabilization following treatment with MM017 is independent of the DNA damage response and entirely initiated by the disruption of 60S ribosomal subunit assembly.
A Bioavailable Analog Reduces Tumor Growth in Mouse Xenografts without Overt Toxicity.
[0297] Next, we investigated whether inhibitors of NVL could inhibit the growth of cell line derived xenografts tumors in mice, and whether systemic inhibition of NVL leads to specific toxicities. Through a medicinal chemistry campaign we identified analog MM927 (Table A), which inhibited HCT116 proliferation with an IC50 of 79 nM, five times more potent than the parent compound, MM017. Cells harboring NVL.sup.P307T mutation are relatively resistant to MM927 (IC50=1.67 M), suggesting that MM927 functions similarly to MM017. To interpret the toxicity of MM927 in mice, we first asked whether MM927 also inhibits mouse NVL. To test the potency of MM927 against mouse NVL within the same cell type, we ectopically expressed either human or mouse NVL in NVL.sup.AID/AID cells. Treatment with Ph-IAA degrades the endogenous protein so that the cells must rely solely on ectopically expressed NVL. In the mock infected cells, degrading NVL.sup.AID/AID by the addition of Ph-IAA reduced cell viability as expected, and the viability was completely rescued by expression of either ectopic mouse or human NVL. In these conditions, MM927 inhibited cells expressing ectopic human NVL with an IC50 of 0.051 M, similar to its potency with endogenous NVL, suggesting that NVL overexpression does not substantially alter sensitivity. MM927 also inhibited mouse NVL with an IC50 of 0.207 M, suggesting that adequate plasma concentrations would be capable of inhibiting NVL in normal mouse tissue.
[0298] In pharmacokinetic studies to evaluate the exposure of MM927, a 10 mg/kg intraperitoneal (IP) injection of MM927 led to peak plasma levels (Cmax) of 2510 ng/ml (5.15 M) with an elimination half-life of 101.33 minutes. Plasma exposure was dose-dependent up to 35 mg/kg (IP injection) reaching a maximum concentration at 17.86 M. These levels exceed the anti-proliferative IC99 of MM927 in cells expressing either human or mouse NVL. In a subsequent pharmacodynamic (PD) study, we asked if we could assess on-target NVL inhibition via a subsequent p53 and/or p21 induction in tumor xenografts in mice treated with MM927. We implanted HCT116 NVL.sup.WT and NVL.sup.R403W cells subcutaneously on either flank of the mice and evaluated the levels of p53 and p21 in either tumor at various time points after IP administration of 35 mg/kg of MM927. The p53 protein levels increased 3 hours after injection and p21 increased soon thereafter. Both p53 and p21 remained elevated at 12 hours and decreased to basal levels by 24 hours, consistent with the pharmacokinetic properties of MM927. Importantly, the levels of p53 and p21 induction in tumor xenografts were comparable to 24 hours of continuous MM017 treatment in cultured cells. Critically, NVL.sup.R403W tumors implanted into the same mice on the opposing flank showed no change in p53 and p21, indicating that the observed changes in NVL wild type tumors were the result of NVL inhibition and establishing p53 and p21 as viable PD markers.
[0299] Having established the kinetics of MM927 mediated NVL inhibition in xenograft tumors, we administered 35 mg/kg MM927 IP twice a day for 21 days to mice harboring tumors derived from either HCT116 NVL wild type or NVL.sup.R403W cells. MM927 treatment significantly reduced the rate of growth of NVL.sup.WT tumors but had no significant impact on NVL.sup.R403W tumors. The growth of a single NVL.sup.WT tumor out of 10 analyzed seemed to initially respond to treatment, but later then progressed suggesting an acquired mechanism of resistance. Nonetheless, endpoint tumor measurements made at either the end of treatment or the time of euthanasia demonstrated that MM927 significantly reduced NVL WT tumor burden but had no effect on NVL.sup.R403W tumors. MM927 was detected at micromolar levels in the plasma and tumor of all the treated mice 3 hours after the last treatment dose demonstrating adequate drug exposure over the course of treatment. Importantly, mice treated with MM927 showed no signs of overt toxicity. In addition, there was no significant difference in body weight, levels of red and white blood cells, hemoglobin, platelets, the liver enzyme alanine transaminase, and renal clearance of blood urea nitrogen between vehicle and drug treated groups. Taken together, we concluded that the potent, and bioavailable analog MM927 reduces tumor growth in mouse xenografts by inhibiting NVL without toxicity.
DISCUSSION
[0300] Modern small molecule cancer drugs are ideally optimized to specifically bind a defined protein target to maximize on-target efficacy and minimize off-target toxicity. By contrast, older cancer therapies, which still constitute most small molecule cancer treatments, often influence multiple protein targets leading to poly-pharmacology and target ambiguity (42). Oxaliplatin, for example, is a first line treatment for colorectal cancer, which like its related analogs cisplatin and carboplatin, targets DNA directly leading to DNA adducts that trigger p53 activation through the DNA damage response (15). Oxaliplatin also targets ribosome biogenesis and leads to nucleolar stress, and this activity is through a target other than DNA since neither carboplatin nor cisplatin inhibit ribosome biogenesis (16-18, 43). Recent reports suggest that blocking ribosome production is the on-target activity for oxaliplatin raising the possibility that patients receiving oxaliplatin may have dose limiting toxicities resulting from off-target DNA damaging activity (19). If that is the case, small molecules that selectively target ribosome biogenesis without causing DNA damage may have improved efficacy and reduced toxicity resulting in a wider therapeutic index. Here, we discovered that MM017 and its bioavailable derivative MM927 inhibit NVL to block ribosome assembly, leading to p53 dependent apoptosis. Importantly, we found that MM017 did not trigger the DNA damage response and thus these molecules now provide a tool to specifically target ribosome biogenesis without DNA damage as a confounding factor.
[0301] NVL is a member of the type 2 AAA ATPase family of enzymes, which contain two tandem AAA ATPase domains (D1 and D2), that translocate peptide substrates through the central channel of a stacked, double-hexameric ring structure (2, 34, 40). Substrate capture triggers the formation of a staircase-like assembly which is followed by sequential ATP binding and hydrolysis events at AAA+ subunit interfaces in both D1 and D2 domains (27, 44). Nucleotide hydrolysis at the interface between subunit D and E is a key event in the cyclic translocation mechanism of this enzyme family, as it allows the subunit at the bottom of the staircase to disengage and transition to the topmost position (45). In a cryo-EM structure with catalytically inactive NVL, we found that MM017 bound to the D1 domain of substrate-bound NVL in two sites at the D/E and E/F interface. This structure indicates that MM017 does not inhibit substrate binding but rather blocks the translocation of the substrate through the central channel, either by inhibiting ATP hydrolysis or by preventing subunit repositioning within the staircase arrangement. This mechanism is distinct from NMS-873 and UPCDC30245, non-competitive p97 inhibitors that bind to all six subunits in a symmetric conformation that promotes substrate disengagement (40, 46).
[0302] The discovery of potent, selective, and bioavailable NVL inhibitors indicate that NVL is a ribosome biogenesis enzyme that may be therapeutically targeted with small molecules. The development of NVL inhibitors as cancer drugs will require identifying which tumor types and genotypes are most likely to respond. Myc is a transcription factor that upregulates the transcription of rDNA and the expression of ribosomal proteins that together promote ribosome biogenesis to drive cancer (47). Thus, cancers that depend on the expression of the Myc protein may be more susceptible to NVL inhibition. In addition, in our survey of anti-proliferative activity to more than 900 cancer cell lines, cell lines with p53 mutations were significantly more likely to be resistant to MM017. Consistent with these findings, genome-wide CRISPR screens in a colorectal cancer cell line nominated p53 and its downstream effector p21 as the two most essential genes for MM017 induced cell death. Finally, silencing of p53 in this colorectal cancer cell line protected cells from MM017 induced apoptosis. These findings suggest that cancers expressing wild-type p53 protein will be more likely to respond to NVL inhibition. Although p53 is frequently mutated in cancer, the frequency of mutations varies among different cancer types ranging from more than 90% in non-small cell and small cell lung cancers to less than 20% in leukemias, renal cell cancer, and bone cancers among others (www.cbioportal.com). Our studies also indicate that loss of p53 may be one possible mechanism of resistance, and thus, combination strategies that combine NVL inhibition with drugs that work through alternative pathways may be effective.

Generation of NVL Mutant Cell Lines
[0675] HCT116 cells were transfected with TransIT-LT (Mirus #MIR2304) according to manufacturer's protocol with a guide RNA (either mock or NVL targeting) in the px330 vector (Addgene, #42230), and 10 nM single stranded deoxyoligonucleotide encoding a specific NVL mutation (see below for specific sequences). 72 hours after transfection, cells were selected by MM017 treatment. The resulting cells were evaluated by cresyl violet staining or collected and the relevant NVL mutations were analyzed by either amplicon or sanger sequencing.
Generation of Knock-In Cell Lines
[0676] Guide RNA targeting genomic region surrounding the stop codon of the targeted gene was cloned into pX330. The repair template was constructed in a pGEM-T Easy Vector to include 1 kilobase homology arms matching upstream and downstream sequences of the genomic locus. The repair template sequence contains the knock-in construct, as well as an IRES Neo cassette flanked by two LoxP sites. Plasmid was sequence verified. Cells were transfected with the guide RNA and the repair template using TransIT LT. Cells were selected with G418 (1 mg/mL) for 2 weeks. Single clones were verified by Western blotting.
Genome-Wide CRISPR/Cas9 Knockout Screen
[0677] HCT116 cells stably expressing Cas9 were generated by infecting cells with lentiCas9-Blast (Addgene #52962) and selection with 10 g/mL blasticidin. A Cas9-expressing clone was isolated and expanded to confirm Cas9 protein expression by Western blotting. Lentivirus carrying the human Brunello CRISPR knockout pooled sgRNA library was prepared and provided by Anderson Frank in the McFadden lab. 300 million cells were infected in 8 g/mL polybrene (Sigma) at a multiplicity of infection of approximately 30% and selected with puromycin (2 g/mL) for 7 days. Approximately 150 million cells were maintained at each passage for each condition: vehicle (DMSO) or 1 M MM017. Cells were treated for 24 hours with vehicle or MM017 and allowed to recover in fresh media without compound until confluency. Viable cells were counted at each passage and collected after 21 days. Genomic DNA was extracted using Blood & Cell Culture DNA Maxi kit (QIAGEN #13362), and concentrations were determined using Quant-iT PicoGreen dsDNA assay kits (Invitrogen #P7589). sgRNAs were PCR-amplified using 28 cycles from approximately 650 g genomic DNA (10 g DNA/100 L reaction) using Ex Taq DNA Polymerase (TaKaRa #RR001B), 8 staggered P5 primers, and 1 unique P7 index primer per sample as described in the Protocol PCR of sgRNAs from gDNA for Illumina sequencing published by the Broad Institute (51). PCR products were purified using SPRIselect bead-based reagent (Beckman #B23318) before sequencing on NextSeq 2000 P2 flowcell (100 cycles, 400M reads) at UTSW McDermott Center Next Generation Sequencing Core. Burrows-Wheeler Aligner (BWA, v0.7.17) was used to map the sequencing reads to the sgRNA sequences concatenated with 5 and 3 flanking sequences. The mapping reads were counted for each sgRNA using SAMtools (v1.9) with the options -F 2308-q 1. MAGeCK was used to determine the relative depletion and enrichment of genes in test samples compared to the control sample. The size factor was estimated using control sgRNAs in normalization.
Pharmacokinetic Studies.
[0678] Pharmacokinetic studies were performed by dosing 6-7 week old CD-1 female mice with analog MM927 formulated as 10% DMSO/10% Kolliphor EL/10% Solutal/70% D5W via the intraperitoneal route. Animals were euthanized in groups of three, blood was obtained by cheek bleeds at each time point (0, 10, 30, 90, 180, 360, 960 and 1440 minutes post dose) using the anticoagulant ACD (acidified citrate dextrose) and plasma isolated by centrifugation. For the dose escalation study, mice were dosed with 20 mg/kg, 35 mg/kg, or 60 mg/kg and blood was collected at 10, 180, and 720 minutes post dose. For the efficacy study, blood and tumor tissue was collected from tumor bearing NOD.CB17-Prkdc.sup.scid Il2rg.sup.tmlWjl/SzJ (NSG) mice (Jackson Laboratories, Bar Harbor, ME) 3 hours after the final dose of MM927 or vehicle (from 10 mice per group). Aliquots of plasma or tumor tissue homogenate were mixed with a two-fold volume of methanol containing 0.15% formic acid and 37.5 ng/mL N-benzylbenzamide internal standard. The samples were vortexed 15 sec, incubated at room temp for 10 and spun twice at 16,100g 4 C. in a refrigerated microcentrifuge. The resulting supernatants were evaluated by LC-MS/MS using a Sciex (Framingham, MA) 4500 Triple Quad coupled to a Shimadzu (Columbia, MD) Prominence LC. Briefly, MM927 was detected in multiple reaction monitoring mode (MRM) using the (m+1) transition 488.059/176.1. N-benzylbenzamide (transition 212.12/91.2) was used as an internal standard. Samples were chromatographed prior to introduction into the mass spectrometer using a C18 column (Agilent XDB column, 5 micron packing, 504.6 mm) with the following conditions. Buffer A (water+0.1% formic acid) and Buffer B (MeOH+0.1% formic acid) were used to create a gradient over the following times: 0-1.5 min 3% B, 1.5-2.0 min gradient to 100% B, 2.0-3.5 min 100% B, 3.5-3.6 min gradient to 3% B, 3.6-4.5 min 3% B. Standard curves were generated using nave tumor tissue or blank plasma (Bioreclamation, Westbury, NY) spiked with known concentrations of analog MM927 and processed as described above. The concentrations of drug in each time-point sample were quantified using Analyst software (Sciex). A value of 3-fold above the signal obtained from blank plasma was designated the limit of detection (LOD). The limit of quantitation (LOQ) was defined as the lowest concentration at which back calculation yielded a concentration within 20% of theoretical and which was above the LOD. Cmax and AUC values were calculated using the noncompartmental analysis tool of Phoenix WinNonLin (Certara/Pharsight, Sunnyvale, CA).
Pharmacodynamic and Efficacy Studies
[0679] Pharmacodynamic study: Five million parental HCT116 cells or HCT116 NVL.sup.R403W in a volume of 0.1 mL were implanted using a subcutaneous injection in the left and right side of four-to-eight-week-old male and female NSG mice, respectively. Tumor volumes were measured every 2 to 4 days with calipers. When the tumor diameter reached 0.5 cm in diameter, mice were dosed with 35 mg/kg MM927 or vehicle formulated as 10% DMSO/10% Kolliphor EL/10% Solutal/70% D5W and administered via the intraperitoneal route. At each time point (0, 3, 6, 12, 24 hours post dose), tumors were harvested and flash frozen for Western blot analysis for p53 and p21 as described.
[0680] Efficacy study: Five million parental HCT116 cells or HCT116 NVL.sup.R403W in a volume of 0.1 mL were implanted in the right flank. Tumor volumes were measured every 2 to 4 days with calipers. Volume is calculated as [(L*W.sup.2)*3.14]/6. When volumes reached 110 mm.sup.3, treatment was started with 35 mg/kg MM927 or vehicle control (0.2 mL/mouse) twice a day for 21 days. Mice were euthanized at the end of the 21-day treatment period or when any tumor reached 2 cm in its largest diameter, in agreement with the approved animal protocol. At the end of treatment, blood and tumor tissue were collected for pharmacokinetic analysis, measurement of complete blood counts, and blood chemistry measurements as described. Serum alanine transaminase and blood urea nitrogen were analyzed using VITROS MicroSlide technology.
Cell Based Cytotoxicity Assay in HCT116 Human Colorectal Cancer Cells.
[0681] Cell culture: The HCT116 cell line was obtained from ATCC and cultured in Dulbecco's Modified Eagle's Medium (DMEM)-high glucose (Sigma Aldrich #D5796) supplemented with 10% fetal bovine serum (FBS) (Sigma-Aldrich #F2442) and 2 mM L-Glutamine (Sigma Aldrich #G7513). Cells were cultured at 37 C. in 5% CO.sub.2. The identity of all cell lines was confirmed by short tandem repeat (STR) analysis and confirmed to be mycoplasma-free using a PCR based assay (Genatlantis).
[0682] Cell viability assay: In 96-well assay plates (Corning #2903), 2,000 cells were plated per well in 100 L of medium and allowed to adhere overnight. The next day, compounds suspended in DMSO were dispensed to the assayed wells using a D300e Digital Dispenser (Tecan). All wells were normalized to 0.5% DMSO. 72 hours after incubation at 37 C. in 5% CO.sub.2, cell viability was assayed using an ATP-based luminescent viability assay, CellTiter-Glo (Promega #G8462). Substrate was mixed 1:1 with phosphate-buffered saline (PBS) supplemented with 1% Triton X-100, and 40 L of this mixture was added to the assay wells. Plates were shaken on a microplate shaker for 10 minutes at room temperature. Luminescence (CellTiter-Glo) was recorded using a Synergy 2 microplate reader (BioTek). In Prism 9 software (GraphPad), ten-point dose response curves were plotted with baseline-correction to the vehicle control well, and IC50 values were calculated by curve fitting using asymmetric (five parameter), least squares fit.
[0683] The analogs in Tables 1-10 using the above cell viability assay are listed as highly active (+++; IC50<500 nM), intermediate active (++; IC50 between 500-1,000 nM), or moderately active (+; IC50 between 1,000 and 5,000 nM).
