(960) Definitions
(961) It is further appreciated that certain features of the disclosure, which are, for clarity, described in the context of separate embodiments, can also be provided in combination in a single embodiment (i.e., as if the embodiments are multiply dependent claims). Conversely, various features of the disclosure which are, for brevity, described in the context of a single embodiment, can also be provided separately or in any suitable subcombination. This disclosure is intended to include all combinations of embodiments for each variable described hereinabove including salts thereof. In particular, the S, P, and L embodiments can be combined as if they were written in multiply dependent claims.
(962) At various places in the present specification, divalent linking substituents are described. It is specifically intended that each divalent linking substituent include both the forward and backward forms of the linking substituent. For example, —NR(CR′R″).sub.n— includes both —NR(CR′R″).sub.n— and —(CR′R″).sub.nNR—. Where the structure clearly requires a linking group, the Markush variables listed for that group are understood to be linking groups.
(963) The term “n-membered” where n is an integer typically describes the number of ring-forming atoms in a moiety where the number of ring-forming atoms is n. For example, piperidinyl is an example of a 6-membered heterocycloalkyl ring, pyrazolyl is an example of a 5-membered heteroaryl ring, pyridyl is an example of a 6-membered heteroaryl ring, and 1,2,3,4-tetrahydro-naphthalene is an example of a 10-membered cycloalkyl group.
(964) As used herein, the phrase “optionally substituted” means unsubstituted or substituted. The substituents are independently selected, and substitution may be at any chemically accessible position. As used herein, the term “substituted” means that a hydrogen atom is removed and replaced by a substituent. A single divalent substituent, e.g., oxo, can replace two hydrogen atoms. It is to be understood that substitution at a given atom is limited by valency, that the designated atom's normal valency is not exceeded, and that the substitution results in a stable compound.
(965) As used herein, the phrase “each ‘variable’ is independently selected from” means substantially the same as wherein “at each occurrence ‘variable’ is selected from.”
(966) When any variable (e.g., R.sup.S) occurs more than one time in any constituent or formula for a compound, its definition at each occurrence is independent of its definition at every other occurrence. Thus, for example, if a group is shown to be substituted with 1, 2, 3, or 4 R.sup.S, then said group may optionally be substituted with up to four R.sup.S groups and R.sup.S at each occurrence is selected independently from the definition of R.sup.S. Also, combinations of substituents and/or variables are permissible only if such combinations result in stable compounds; for example the combination of a first M group and second M group in the combination of two R groups are permissible only if such combinations of M-M result in stable compounds (e.g., M-M is not permissible if it will form highly reactive compounds such as peroxides having O—Obonds).
(967) Throughout the definitions, the term “C.sub.n-m” indicates a range which includes the endpoints, wherein n and m are integers and indicate the number of carbons. Examples include C.sub.1-3, C.sub.1-4, C.sub.1-6, and the like.

(1122) The reactions for preparing compounds of the disclosure can be carried out in suitable solvents which can be readily selected by one of skill in the art of organic synthesis. Suitable solvents can be substantially non-reactive with the starting materials (reactants), the intermediates or products at the temperatures at which the reactions are carried out, e.g., temperatures which can range from the solvent's freezing temperature to the solvent's boiling temperature. A given reaction can be carried out in one solvent or a mixture of more than one solvent. Depending on the particular reaction step, suitable solvents for a particular reaction step can be selected by the skilled artisan.
(1123) Preparation of compounds of the disclosure can involve the protection and deprotection of various chemical groups. The need for protection and deprotection, and the selection of appropriate protecting groups, can be readily determined by one skilled in the art. The chemistry of protecting groups is described, e.g., in Kocienski, Protecting Groups, (Thieme, 2007); Robertson, Protecting Group Chemistry, (Oxford University Press, 2000); Smith et al., March's Advanced Organic Chemistry: Reactions, Mechanisms, and Structure, 6.sup.th Ed. (Wiley, 2007); Peturssion et al., “Protecting Groups in Carbohydrate Chemistry,” J. Chem. Educ., 1997, 74(11), 1297; and Wuts et al., Protective Groups in Organic Synthesis, 4th Ed., (Wiley, 2006).
(1124) Reactions can be monitored according to any suitable method known in the art. For example, product formation can be monitored by spectroscopic means, such as nuclear magnetic resonance spectroscopy (e.g., .sup.1H or .sup.13C), infrared spectroscopy, spectrophotometry (e.g., UV-visible), mass spectrometry or by chromatographic methods such as high performance liquid chromatography (HPLC) or thin layer chromatography (TLC).
(1125) The expressions, “ambient temperature” and “room temperature,” as used herein, are understood in the art, and refer generally to a temperature, e.g., a reaction temperature, that is about the temperature of the room in which the reaction is carried out, e.g., a temperature from about 20° C. to about 30° C.
(1126) The Schemes below provide general guidance in connection with preparing the compounds of the disclosure. One skilled in the art would understand that the preparations shown in the Schemes can be modified or optimized using general knowledge of organic chemistry to prepare various compounds of the disclosure.
(1127) The P ligands of Formula (P-1), (P-1a), and (P-1b) (and embodiments thereof) can be synthesized as described in US Patent Publ. Nos. 20180179201, 20180179197, 20180179179, 20180179202, 20180177784, 20180177870, 20190300524, and 20190345170, each of which is incorporated herein by reference in its entirety.

Nucleophilic aromatic substitution of an appropriately functionalized nitro-halo-phenyl compound 1-1 with an amine containing a linker group L.sup.Y 1-2 can afford compound 1-3. Reduction of the aromatic nitro group followed by ring closing reaction with cyanogen bromide can provide the aminobenzimidazole 1-5. Amide coupling of compound 1-5 with carboxylic acid 1-6 can generate the aminobenzimidazole 1-7. Removal of the Boc protecting group in 1-7 can afford the amine 1-8 which can be converted to the alcohol 1-9 under Sandmeyer conditions. The compound 1-10 could be achieved by reacting the alcohol 1-9 with phosphorus (III) bromide.
(1132) ##STR00077##
(1133) Compounds of formula 2-8 can be synthesized using a process shown in Scheme 2. Palladium-catalyzed cross-coupling reactions of the appropriate aryl halides and boronic acids/esters can produce the biaryl compounds of formula 2-5. Under deoxygenation conditions, the in-situ generated nitrene from compound 2-5 can insert into the adjacent aromatic C-H bond and afford the tricyclic compound 2-6. Suzuki coupling of the aryl-Cl 2-6 with aromatic boronic ester 2-7 can furnish the compounds of formula 2-8.
(1134) ##STR00078##
(1135) As shown in Scheme 3, reactions of compounds 3-1 and 3-2 under basic conditions can afford the compound of Formula (S-2).
(1136) ##STR00079##
(1137) The S moieties of Formula (S-3) can be synthesized according to Scheme 4. First, intermediates 4-1 and 4-4 are synthesized by methods analogous to those in Scheme 2. Then, as shown in Scheme 4, reactions of compounds 4-1 and excess 4-2 under basic conditions can afford the compound of formula 4-3. Further reaction of compounds 4-3 and 4-4 under alkylation conditions such as in the presence of suitable base and a polar solvent can generate the target moiety of Formula (S-3).
(1138) ##STR00080##
(1139) The S moieties of Formula (S-4) can be synthesized according to Schemes 5-6. Accordingly, intermediates 5-8 can be synthesized using a process shown in Scheme 5. Nucleophilic aromatic substitution of an appropriately functionalized nitro-halo-phenyl compound 5-1 with an amine containing a linker group L.sup.Y of formula 5-2 can afford compound 5-3. Alternatively, transition metal (including, but not limited to, Pd and Cu) catalyzed C—N bond forming reactions may also be used to provide compound 5-3. Reduction of the aromatic nitro group followed by ring closing reaction with cyanogen bromide can provide the aminobenzimidazole 5-5. Amide coupling of compound 5-5 with carboxylic acid 5-6 can generate the aminobenzimidazole 5-7. Removal of the Boc protecting group in 5-7 can then afford the amine 5-8.
(1140) ##STR00081##
(1141) Compounds of Formula (S-4) can be synthesized using a process shown in Scheme 6. Cyclization of halo-benzene compound 6-1 in one or more steps provides an appropriately functionalized bicyclic nitro-halo-phenyl compound 6-2. Nucleophilic aromatic substitution of compound 6-2 with amine 5-8 can afford compound 6-4. Alternatively, transition metal (e.g. Pd, Cu, etc.) catalyzed C—N bond forming reactions may also be used to provide compound 6-4. Reduction of the aromatic nitro group followed by ring closing reaction with cyanogen bromide can provide the aminobenzimidazole 6-6. Amide coupling of compound 6-6 with carboxylic acid 6-7 can generate the amide 6-8.
(1142) ##STR00082##
(1143) Conjugates of formula 7-5 can be synthesized using a process shown in Scheme 7. The S moiety 7-1 with un-protected amine and an appropriate linker 7-2 (e.g. peptide, polyethylene glycol, and etc.), with an Fmoc protected amine capped at one end and a naked carboxylic acid capped at the other end, are linked together under standard amide coupling conditions (e.g. BOP, HATU, etc.). After a same pot Fmoc removal, free amine 7-3 can be obtained. Following another amide coupling with PD-L1 protein ligand moiety containing carboxylic acid 7-4, which can be synthesized following the method we published previously, under standard conditions, the desired conjugate 7-5 can be obtained.
(1144) ##STR00083##
(1145) A conjugate of formula 8-4 with a cleavable dipeptide linker can be synthesized using a process shown in Scheme 8. The S moiety 7-1 with un-protected amine is coupled with commercially available 8-1 under standard carbamate formation conditions (e.g. DMAP and etc). After removal of Fmoc protection, free amine 8-2 can be obtained. After a sequence of amide coupling with an appropriate linker 7-2 and Fmoc deprotection will arrive at free amine 2-3. The desired conjugate 8-4 can be obtained by coupling the thus obtained amine 8-3 and PD-L1 protein ligand 7-4 under standard amide coupling conditions.
(1146) ##STR00084##
(1147) Conjugates having a disulfide linkage 9-5 can be prepared according to Scheme 9. Trityl protected thioamine 9-1 can be coupled to the PD-L1 ligand 7-4 under standard amide coupling conditions. After deprotection of trityl, thiol 9-2 can be obtained. On the other hand, STING agonist moiety 7-1 with un-protected amine is coupled with disulfide 9-3 under DMAP mediated carbamate formation condition to generate disulfide 9-4. Thus obtained thiol 9-2 and disulfide 9-4 can do disulfide exchange to afford the desired conjugate 9-5.
(1148) ##STR00085##
(1149) Alternatively, disulfide linkage containing conjugate 10-5 can be prepared according to Scheme 10. Azido amine 10-1 can be coupled to the PD-L1 ligand 7-4 under standard amide coupling conditions to provide azide 10-2. On the other hand, S moiety 7-1 with un-protected amine is coupled with 2-((2-(prop-2-yn-1-yloxy)ethyl)disulfanyl)ethan-1-ol 10-3 under CDI mediated carbamate formation condition to generate alkyne 10-4. Thus obtained azide 10-2 and alkyne 10-4 can be tethered together under standard click chemistry conditions (e.g. CuSO.sub.4) to afford the desired conjugate 10-5.

In some embodiments, the lactose monohydrate is Fast-flo 316™. In some embodiments, the hydroxypropyl methylcellulose is hydroxypropyl methylcellulose 2208 K4M (e.g., Methocel K4 M Premier™) and/or hydroxypropyl methylcellulose 2208 K100LV (e.g., Methocel K00LV™). In some embodiments, the polyethylene oxide is polyethylene oxide WSR 1105 (e.g., Polyox WSR 1105™).
(1158) In some embodiments, a wet granulation process is used to produce the composition. In some embodiments, a dry granulation process is used to produce the composition.
(1159) The compositions can be formulated in a unit dosage form, each dosage containing from about 0.5 to about 1,000 mg, or from about 5 to about 1,000 mg (1 g), or from about 100 mg to about 500 mg, of the active ingredient. In some embodiments, each dosage contains about 1 mg of the active ingredient. In some embodiments, each dosage contains about 5 mg of the active ingredient. In some embodiments, each dosage contains about 10 mg of the active ingredient. In some embodiments, each dosage contains about 50 mg of the active ingredient. In some embodiments, each dosage contains about 25 mg of the active ingredient. 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.
(1160) The components used to formulate the pharmaceutical compositions are of high purity and are substantially free of potentially harmful contaminants (e.g., at least National Food grade, generally at least analytical grade, and more typically at least pharmaceutical grade). Particularly for human consumption, the composition is preferably manufactured or formulated under Good Manufacturing Practice standards as defined in the applicable regulations of the U.S. Food and Drug Administration. For example, suitable formulations may be sterile and/or substantially isotonic and/or in full compliance with all Good Manufacturing Practice regulations of the U.S. Food and Drug Administration.
(1161) The active compound may be effective over a wide dosage range and is generally administered in a therapeutically effective amount. It will be understood, however, that the amount of the compound actually administered will usually be determined by a physician, according to the relevant circumstances, including the condition to be treated, the chosen route of administration, the actual compound administered, the age, weight, and response of the individual patient, the severity of the patient's symptoms and the like.
(1162) The therapeutic dosage of a compound of the present disclosure can vary according to, e.g., the particular use for which the treatment is made, the manner of administration of the compound, the health and condition of the patient, and the judgment of the prescribing physician. The proportion or concentration of a compound of the present disclosure in a pharmaceutical composition can vary depending upon a number of factors including dosage, chemical characteristics (e.g., hydrophobicity), and the route of administration. For example, the compounds of the present disclosure can be provided in an aqueous physiological buffer solution containing from about 0.01 to about 10% w/v, or from about 0.1 to about 10% w/v, of the compound for parenteral administration. Some typical dose ranges are from about 0.1 μg/kg to about 1 g/kg, or from about 1 μg/kg to about 1 g/kg, of body weight per day. In some embodiments, the dose range is from about 0.001 mg/kg to about 100 mg/kg, or from about 0.01 mg/kg to about 100 mg/kg, of body weight per day. The dosage is likely to depend on such variables as the type and extent of progression of the disease or disorder, the overall health status of the particular patient, the relative biological efficacy of the compound selected, formulation of the excipient, and its route of administration. Effective doses can be extrapolated from dose- response curves derived from in vitro or animal model test systems.
(1163) For preparing solid compositions such as tablets, the principal active ingredient is mixed with a pharmaceutical excipient to form a solid preformulation composition containing a homogeneous mixture of a compound of the present disclosure. When referring to these preformulation compositions as homogeneous, the active ingredient is typically dispersed evenly throughout the composition so that the composition can be readily subdivided into equally effective unit dosage forms such as tablets, pills and capsules. This solid preformulation is then subdivided into unit dosage forms of the type described above containing from, e.g., about 0.01 to about 1000 mg, or about 0.1 to about 1000 mg, of the active ingredient of the present disclosure.
(1164) The tablets or pills of the present disclosure can be coated or otherwise compounded to provide a dosage form affording the advantage of prolonged action. For example, the tablet or pill can comprise an inner dosage and an outer dosage component, the latter being in the form of an envelope over the former. The two components can be separated by an enteric layer which serves to resist disintegration in the stomach and permit the inner component to pass intact into the duodenum or to be delayed in release. A variety of materials can be used for such enteric layers or coatings, such materials including a number of polymeric acids and mixtures of polymeric acids with such materials as shellac, cetyl alcohol and cellulose acetate.
(1165) The liquid forms in which the compounds and compositions of the present disclosure can be incorporated for administration orally or by injection include aqueous solutions, suitably flavored syrups, aqueous or oil suspensions, and flavored emulsions with edible oils such as cottonseed oil, sesame oil, coconut oil, or peanut oil, as well as elixirs and similar pharmaceutical vehicles.
(1166) Compositions for inhalation or insufflation include solutions and suspensions in pharmaceutically acceptable, aqueous or organic solvents, or mixtures thereof, and powders. The liquid or solid compositions may contain suitable pharmaceutically acceptable excipients as described supra. In some embodiments, the compositions are administered by the oral or nasal respiratory route for local or systemic effect. Compositions can be nebulized by use of inert gases. Nebulized solutions may be breathed directly from the nebulizing device or the nebulizing device can be attached to a face mask, tent, or intermittent positive pressure breathing machine. Solution, suspension, or powder compositions can be administered orally or nasally from devices which deliver the formulation in an appropriate manner
(1167) Topical formulations can contain one or more conventional carriers. In some embodiments, ointments can contain water and one or more hydrophobic carriers selected from, e.g., liquid paraffin, polyoxyethylene alkyl ether, propylene glycol, white Vaseline, and the like. Carrier compositions of creams can be based on water in combination with glycerol and one or more other components, e.g., glycerinemonostearate, PEG-glycerinemonostearate and cetylstearyl alcohol. Gels can be formulated using isopropyl alcohol and water, suitably in combination with other components such as, e.g., glycerol, hydroxyethyl cellulose, and the like. In some embodiments, topical formulations contain at least about 0.01, at least about 0.05, at least about 0.1, at least about 0.25, at least about 0.5, at least about 1, at least about 2 or at least about 5 wt % of the compound of the present disclosure. The topical formulations can be suitably packaged in tubes of, e.g., 100 g which are optionally associated with instructions for the treatment of the select indication, e.g., psoriasis or other skin condition.
(1168) The amount of compound or composition administered to a patient will vary depending upon what is being administered, the purpose of the administration, such as prophylaxis or therapy, the state of the patient, the manner of administration and the like. In therapeutic applications, compositions can be administered to a patient already suffering from a disease in an amount sufficient to cure or at least partially arrest the symptoms of the disease and its complications. Effective doses will depend on the disease condition being treated as well as by the judgment of the attending clinician depending upon factors such as the severity of the disease, the age, weight and general condition of the patient and the like.
(1169) The compositions administered to a patient can be in the form of pharmaceutical compositions described above. These compositions can be sterilized by conventional sterilization techniques, or may be sterile filtered. Aqueous solutions can be packaged for use as is, or lyophilized, the lyophilized preparation being combined with a sterile aqueous carrier prior to administration. The pH of the compound preparations typically will be between 3 and 11, more preferably from 5 to 9 and most preferably from 7 to 8. It will be understood that use of certain of the foregoing excipients, carriers or stabilizers will result in the formation of pharmaceutical salts.
(1170) The therapeutic dosage of a compound of the present disclosure can vary according to, e.g., the particular use for which the treatment is made, the manner of administration of the compound, the health and condition of the patient, and the judgment of the prescribing physician. The proportion or concentration of a compound of the present disclosure in a pharmaceutical composition can vary depending upon a number of factors including dosage, chemical characteristics (e.g., hydrophobicity), and the route of administration. For example, the compounds of the present disclosure can be provided in an aqueous physiological buffer solution containing about 0.01 to about 10% w/v, or from about 0.1 to about 10% w/v of the compound for parenteral administration. Some typical dose ranges are from about 0.1 μg/kg to about 1 g/kg, or from about 1 μg/kg to about 1 g/kg, of body weight per day. In some embodiments, the dose range is from about 0.01 mg/kg to about 100 mg/kg of body weight per day. The dosage is likely to depend on such variables as the type and extent of progression of the disease or disorder, the overall health status of the particular patient, the relative biological efficacy of the compound selected, formulation of the excipient, and its route of administration. Effective doses can be extrapolated from dose-response curves derived from in vitro or animal model test systems.
(1171) Labeled Compounds and Assay Methods
(1172) The compounds of the present disclosure can further be useful in investigations of biological processes in normal and abnormal tissues. Thus, another aspect of the present disclosure relates to labeled compounds of the disclosure (radio-labeled, fluorescent-labeled, etc.) that would be useful not only in imaging techniques but also in assays, both in vitro and in vivo, for localizing and quantitating PD-1 or PD-L1 or STING protein in tissue samples, including human, and for identifying PD-L1 or STING ligands by inhibition binding of a labeled compound. Substitution of one or more of the atoms of the compounds of the present disclosure can also be useful in generating differentiated ADME (Adsorption, Distribution, Metabolism and Excretion). Accordingly, the present disclosure includes PD-1/PD-L1 or STING binding assays that contain such labeled compounds.
(1173) The present disclosure further includes isotopically-substituted compounds of the disclosure. An “isotopically-substituted” compound is a compound of the disclosure where one or more atoms are replaced or substituted by an atom having an atomic mass or mass number from the atomic mass or mass number typically found in nature (i.e., naturally occurring). Suitable radionuclides that may be incorporated in compounds of the present disclosure include but are not limited to .sup.2H, .sup.3H (also written as T for tritium), .sup.11C, .sup.13C, .sup.14C, .sup.13N, .sup.15N, .sup.15O, .sup.17O, .sup.18O, .sup.18F, .sup.35S, .sup.36Cl, .sup.82Br, .sup.75Br, .sup.76Br, .sup.77Br, .sup.123I, .sup.124I, .sup.125I, and .sup.131I. For example, one or more hydrogen atoms in a compound of the present disclosure can be replaced by deuterium atoms (e.g., one or more hydrogen atoms of a C.sub.1-6 alkyl group of Formula (I) can be optionally substituted with deuterium atoms, such as —CD.sub.3 being substituted for —CH.sub.3). In some embodiments, alkyl groups of the disclosed Formulas (e.g., Formula (I), (II), etc.), can be perdeuterated.
(1174) One or more constituent atoms of the compounds presented herein can be replaced or substituted with isotopes of the atoms in natural or non-natural abundance. In some embodiments, the compound includes at least one deuterium atom. For example, one or more hydrogen atoms in a compound presented herein can be replaced or substituted by deuterium (e.g., one or more hydrogen atoms of a C.sub.1-6 alkyl group can be replaced by deuterium atoms, such as —CD.sub.3 being substituted for —CH.sub.3). In some embodiments, the compound includes two or more deuterium atoms. In some embodiments, the compound includes 1, 1-2, 1-3, 1-4, 1-5, 1-6, 1-7, 1-8, or 1-9 deuterium atoms. In some embodiments, all of the hydrogen atoms in a compound can be replaced or substituted by deuterium atoms.
(1175) Synthetic methods for including isotopes into organic compounds are known in the art (Deuterium Labeling in Organic Chemistry by Alan F. Thomas (New York, N.Y., Appleton-Century-Crofts, 1971; The Renaissance of H/D Exchange by Jens Atzrodt, Volker Derdau, Thorsten Fey and Jochen Zimmermann, Angew. Chem. Int. Ed. 2007, 7744-7765; The Organic Chemistry of Isotopic Labelling by James R. Hanson, Royal Society of Chemistry, 2011). Isotopically labeled compounds can be used in various studies such as NMR spectroscopy, metabolism experiments, and/or assays.
(1176) Substitution with heavier isotopes, such as deuterium, may afford certain therapeutic advantages resulting from greater metabolic stability, for example, increased in vivo half-life or reduced dosage requirements, and hence may be preferred in some circumstances. (see e.g., A. Kerekes et.al. J. Med. Chem. 2011, 54, 201-210; R. Xu et.al. J. Label Compd. Radiopharm. 2015, 58, 308-312). In particular, substitution at one or more metabolism sites may afford one or more of the therapeutic advantages.
(1177) The radionuclide that is incorporated in the instant radio-labeled compounds will depend on the specific application of that radio-labeled compound. For example, for in vitro PD-L1 protein labeling and competition assays, compounds that incorporate .sup.3H, .sup.14C, .sup.82Br, .sup.125I, .sup.131I, or .sup.35S or can generally be useful.
(1178) It is understood that a “radio-labeled” or “labeled compound” is a compound that has incorporated at least one radionuclide. For radio-imaging applications .sup.11C, .sup.18F, .sup.125I, .sup.123I, .sup.124I, .sup.131I, .sup.75Br, .sup.76Br or .sup.77Br will generally be most useful. In some embodiments the radionuclide is selected from the group consisting of .sup.3H, .sup.14C, .sup.125I, .sup.355 and .sup.82Br.
(1179) The present disclosure can further include synthetic methods for incorporating radio-isotopes into compounds of the disclosure. Synthetic methods for incorporating radio-isotopes into organic compounds are well known in the art, and an ordinary skill in the art will readily recognize the methods applicable for the compounds of disclosure.
(1180) A labeled compound of the disclosure can be used in a screening assay to identify and/or evaluate compounds. For example, a newly synthesized or identified compound (i.e., test compound) which is labeled can be evaluated for its ability to bind a PD-L1 protein by monitoring its concentration variation when contacting with the PD-L1 protein, through tracking of the labeling. For example, a test compound (labeled) can be evaluated for its ability to reduce binding of another compound which is known to bind to a PD-L1 protein (i.e., standard compound). Accordingly, the ability of a test compound to compete with the standard compound for binding to the PD-L1 protein directly correlates to its binding affinity. Conversely, in some other screening assays, the standard compound is labeled and test compounds are unlabeled. Accordingly, the concentration of the labeled standard compound is monitored in order to evaluate the competition between the standard compound and the test compound, and the relative binding affinity of the test compound is thus ascertained.
(1181) Kits
(1182) The present disclosure also includes pharmaceutical kits useful, e.g., in the treatment or prevention of diseases or disorders associated with the activity of PD-L1 or STING including its interaction with other proteins such as PD-1 and B7-1 (CD80), such as cancer or infections, which include one or more containers containing a pharmaceutical composition comprising a therapeutically effective amount of a compound of Formula (I), or any of the embodiments thereof. Such kits can further include one or more of various conventional pharmaceutical kit components, such as, e.g., containers with one or more pharmaceutically acceptable carriers, additional containers, etc., as will be readily apparent to those skilled in the art. Instructions, either as inserts or as labels, indicating quantities of the components to be administered, guidelines for administration, and/or guidelines for mixing the components, can also be included in the kit.

Examples 1A and 1B: PD-1/PD-L1 Binding Assay
Example 1A: Alphascreen
(2228) Binding assays were conducted in a low volume white 384-well polystyrene plate in a final volume of 20 μL. Compounds to be analyzed were first serially diluted in DMSO and added to the plate wells before the addition of other reaction components. The final concentration of DMSO in the assay was 1%. The assay was carried out at 25° C. in the PBS buffer (pH 7.4) with 0.05% Tween-20 and 0.1% BSA. Recombinant human PD-L1 protein (19-238) with a His-tag at the C-terminus was purchased from AcroBiosystems (PD1-H5229). Recombinant human PD-1 protein (25-167) with Fc tag at the C-terminus was also from AcroBiosystems (PD1-H5257). PD-L1 and PD-1 proteins were diluted in the assay buffer (final concentration—0.67 and 0.20 nM respectively) and 10 μL was added to the plate well. Plates were centrifuged and proteins were preincubated with compounds for 40 minutes. The incubation was followed by the addition of 10 μL of assay buffer supplemented with Alphascreen Ni chelate donor beads (PerkinElmer—AS101D) and Protein A Acceptor beads (PerkinElmer—6760137) at final concentration 2.5 μg/mL under reduced light. After plate sealing, the plate was incubated in the dark at room temperature for 120 minutes before reading on a PHERAstar FS plate reader (BMG Labtech). IC.sub.50 determination was performed by fitting the curve of percent control activity versus the log of the compound concentration using the GraphPad Prism 5.0 software.
Example 1B; Homogeneous Time-Resolved Fluorescence (HTRF)
(2229) The assays were conducted in a standard black 384-well polystyrene plate with a final volume of 20 μL. Inhibitors were first serially diluted in DMSO and then added to the plate wells before the addition of other reaction components. The final concentration of DMSO in the assay was 1%. The assays were carried out at 25° C. in the PBS buffer (pH 7.4) with 0.05% Tween-20 and 0.1% BSA. Recombinant human PD-L1 protein (19-238) with a His-tag at the C-terminus was purchased from AcroBiosystems (PD1-H5229).

PD-L1 and PD-1 proteins were diluted in the assay buffer and 10 μL was added to the plate well. Plates were centrifuged and proteins were preincubated with inhibitors for 40 minutes. The incubation was followed by the addition of 10 μL of HTRF detection buffer supplemented with Europium cryptate-labeled anti-human IgG (PerkinElmer-AD0212) specific for Fc and anti-His antibody conjugated to SureLight®-Allophycocyanin (APC, PerkinElmer-AD0059H). After centrifugation, the plate was incubated at 25° C. for 60 min. before reading on a PHERAstar FS plate reader (665 nm/620 nm ratio). Final concentrations in the assay were −3 nM PD1, 10 nM PD-L1, 1 nM europium anti-human IgG and 20 nM anti-His-Allophycocyanin.ICso determination was performed by fitting the curve of percent control activity versus the log of the inhibitor concentration using the GraphPad Prism 5.0 software.
Example 2A: PD-L1 Homogeneous Time-Resolved Fluorescence (HTRF) Dimerization Assay
(2230) Dimerization assays were conducted in a standard black 384-well polystyrene plate in a final volume of 20 μL. Compounds to be analyzed were diluted in DMSO and added to the plate wells before the addition of other reaction components. The final concentration of tested compounds was 10 μM and DMSO was at 1%. The assays were carried out at 25° C. in PBS buffer (pH 7.4) with 0.05% Tween-20 and 0.1% BSA. Recombinant human PD-L1 protein (19-238) with a His-tag at the C-terminus was purchased from AcroBiosystems (PD1-H5229). Recombinant human PD-L1 protein (19-239) with Fc tag at the C-terminus was purchased from BPS Bioscience (#71104). PD-L1 proteins were diluted in the assay buffer, mixed, and 10 ul was added to the plate well. Plates were centrifuged and proteins were preincubated with compounds for 40 minutes. The incubation was followed by the addition of 10 μL of HTRF detection buffer supplemented with Europium cryptate-labeled anti-human IgG (PerkinElmer-AD0074) specific for Fc and anti-His antibody conjugated to SureLight®-Allophycocyanin (APC, PerkinElmer-AD0059H). Final concentrations in the assay were: 30 nM PD-L1 (Fc-tag), 100 nM PD-L1 (His-tag), 10 nM europium anti-human IgG and 200 nM anti-His-Allophycocyanin. After centrifugation, the plate was incubated at 25° C. for 60 minutes before reading on a PHERAstar FS plate reader (665 nm/620 nm ratio). The dimerization ratio was calculated based on the assay signal in the presence of compound divided by the signal in the presence of DMSO.
Example 3A: PD-L1 Internalization Assays
(2231) Endocytosis or internalization of PD-L1 was measured by two different methods, one direct and the other indirect. In the direct method, an anti PD-L1 antibody labeled with a pH sensitive fluorophore is incubated with PD-L1 expressing cells. Upon internalization and trafficking of the antibody-PD-L1 complex to low pH endosomes, fluorescence is emitted. In the indirect method, cell surface PD-L1 is measured using an anti PD-L1 antibody after incubation with a compound to determine remaining, non-internalized receptor.
(2232) Direct Method Assessing for PD-L1 Internalization
(2233) For the direct measurement, biotinylated anti-PD-L1 antibody (BPS Biosciences) or Atezolizumab, biotinylated with a 20-fold excess of biotin using the EZ-Link™ Sulfo-NHS-LC-Biotin reagents (ThermoFisher), were labeled with pHrodo™ Red Avidin (Life Technologies) conjugate. Equimolar solutions of the antibody and pHrodo™ Red avidin (4.2 uM each) were incubated on ice for 2 hours in the dark in a buffer composed of 40 mM Tris-HCl, pH 8.0, 110 mM NaCl, 2.2 mM KCl, 20% glycerol, and 1% bovine serum albumin The mixture was centrifuged for 1 minute at 1000 rpm, and the clarified supernatant was used in subsequent assays. As an isotype control, a biotinylated Human IgG1κ antibody (Ancell) was labeled using the same protocol. For the assay, 2×10^5 CHO-PD-L1 cells (Promega) were seeded into each well of a 6-well tissue culture plate in 2 ml of F-12 medium supplemented with 10% FBS, 200 μg/ml Hydromycin and 250 μg/ml Geneticin. Cells were allowed to attach for 24 hours, and then 40 nM of the anti-PD-L1-biotin/pHrodo-Avidin, Atezolizumab/pHrodo-Avidin or IgG-biotin/pHrodo-Avidin complex was added to the cells and allowed to incubate at 37° C. for 5 to 16 hours. The cells were washed twice with PBS (Mg, Ca free) and harvested using non-enzymatic lift buffer (10 mM Tris (pH 7.5), 140 mM NaCl, 1 mM EDTA), collected by centrifugation, and re-suspended in 400 μL of PBS. The cells were analyzed by flow cytometry, and internalized antibody-receptor complex was detected using a C6 Accuri Flow Cytometer (excitation with 488 nM laser and emission collected with a 585/40 bandpass filter). There was no difference between IgG control and Atezolizumab, demonstrating that Atezolizumab dos not cause PD-L1 internalization.
(2234) Indirect Method for Assessing for PD-L1 Internalization
(2235) For the indirect analysis, cell surface PD-L1 was detected with fluorescently labeled anti-PD-L1 (CD274) antibodies. CHO-PD-L1 cells were seeded at 2×10^5 cells per well of a 6-well tissue culture plate in 2 ml of F-12 medium supplemented with 10% FBS, 200 μg/ml Hydromycin and 250 μg/ml Geneticin and allowed to attach for 24 hours. After 24 hours, test compounds were added to a final concentration of 1 uM from DMSO stocks, and an equal volume of DMSO was added to control wells. Cells were incubated in the presence of a compound for 16 hours at 37° C., 5% CO2. Prior to analysis, the cells were washed twice with 1 mL of Ca, Mg free PBS and detached with 1 mL of lift buffer (10 mM Tris, 140 mM NaCl, 1 mM EDTA). The collected cells were stained with PE-conjugated mouse anti-human CD274 antibody according to manufacturer instructions: BD Pharmigen #557924 Clone MIH1 (20 μL of Ab per 100 uL of BSA based staining buffer) or eBioscience #12-5983 Clone MIH1 (2 μL per 100 ul of BSA based staining buffer). Cells were incubated at room temperature for 20 minutes, protected from light, washed twice with Ca, Mg free PBS and resuspended in 400 μL of PBS. Antibody binding was detected by flow cytometry using an Accuri C6 instrument. Isotype control antibody-stained cells were used as a negative control. To test that lack of PD-L1 cell surface staining was not due to inhibition of detection antibody binding by the test article, an acid-wash procedure was used. After 16 hours of incubation in the presence of a compound or anti-PD-L1 antibody, the remaining, non-internalized a compound or antibody was stripped from the cell surface using freshly prepared, ice-cold acid stripping buffer (DMEM/0.2% BSA, pH 3.5). Cells were washed in this manner three times for 5 minutes each on a shaking platform. The stripped cells were then washed with ice-cold PBS three times for 5 minutes each with gentle shaking, harvested with lift buffer and stained with PE-mouse anti human CD274 antibodies as described.
(2236) For the indirect method of assessing PD-L1 internalization using the MDA-MB231 breast cancer cell line, the procedure for the assays was the same as described for the CHO-PD-L1 cells with the following changes. MDA-MB231 were seeded at 2×10^5 cells per well of a 6-well tissue culture plate in 2 ml of RPMI1640 medium supplemented with 10% FBS. After compound treatment for 16 hrs, the cells were treated with the stripping buffer (DMEM/0.2% BSA, pH 3.5) prior to staining with the anti-CD274 antibodies as described.
(2237) Indirect Whole Blood Assay
(2238) To determine PD-L1 internalization in human whole blood, normal human blood (Biological Specialty Corp, Colmar. Pa.) was incubated in the presence or absence of a concentration range of test compounds and 1 ng/ml human interferon γ (R&D Systems Inc. Minn. Minn.) in a 96 well round bottom plate (Corning, Corning, N.Y.) for 18 hours at 37° C. Blood was then transferred into 96 well “2 ml Assay Block” (Corning, Corning N.Y.) and stained with PD-L1 (MIH1, eBioscience; or BD Biosciences San Jose, Calif.), CD14 (Life Technologies, Carlsbad, Calif.) for 30 minutes in the dark at room temperature. Whole Blood/red cells were lysed/fixed (lysis buffer BD Biosciences) for 5 minutes at 37° C. in dark and then centrifuged at 1600 RPM for 5 minutes and cells were transferred into 96 well round bottom plates (Corning). Cells were gated on CD14+ (BD Biosciences) and PD-L1 expression determined by mean fluorescence intensity (MFI) (BD LSRFortessa™ X-20). IC.sub.50 determination was performed by fitting the curve of compound percent inhibition versus the log of the compound concentration using the GraphPad Prism 7.0 software.

Example 5A: Whole Blood Interferon γ Assay
(2243) To determine the increase of Interferon γ in whole blood, normal human blood (Biological Specialty Corp, Colmar. Pa.) diluted 1/10 in AIM-V media (Life Technologies) is incubated in the presence or absence of a concentration range of test compounds and 5 ng/ml Staphylococcal enterotoxin B (Toxin Technologies Sarasota, Fla.) in a 96 well U bottom Tissue Culture Plate (Corning) for 3 days at 37° C. Plates are centrifuged at 1400 RPM for 5 minutes, and supernatants collected and tested for presence of Interferon γ in a commercial Interferon γ ELISA kit (R&D Human IFN-γ Quantikine ELISA (R&D Systems, Minneapolis, Minn.).
Example 6A: Animal Models
(2244) Studies to assess pharmacokinetics, pharmacodynamics, and efficacy are conducted in mice engrafted with human CD34+ cells and mice engineered to express human checkpoint molecules. Both preclinical models have been validated with approved therapeutics targeting the PD-1:PD-L1-axis
(2245) Humanized CD34+ Mice
(2246) Humanized CD34+ mice have been used commonly to study immune-oncology, infectious diseases and graft rejection research. In brief, immune-compromised NSG mice (NOD scid IL2Rg.sup.null; Jackson Laboratory) receive total body irradiation to deplete existing bone marrow cells. CD34+ human stem cells derived from umbilical cord blood are then engrafted to establish a fully human immune system over a 12-14 week period. Alternative mouse strains may also be used to improve the engraftment of stem cells and enhance the development of myeloid lineage cells, which are the main PD-L1-expressing host immune cells. For example, the NSG-SGM3 mice were engineered to produce human cytokines (SCF, IL-3 and GM-CSF) that allow full differentiation of the myeloid lineage [Jackson Laboratory]. Cell-derived xenograft models are selected based on tumor and host PD-L1 expression, as well as their response to anti-PD-L1 antibody treatment. PD-L1 internalization induced by small molecules targeting PD-L1 are the main pharmacodynamic biomarker and are determined by measuring the remaining PD-L1 expression on both tumor and host immune cells.
(2247) Human Checkpoint Molecule Knock-In Mice
(2248) Human-mouse chimeric models have been developed to allow binding of human-specific antibodies to the human protein while using fully intact mouse immune biology. This approach is utilized to evaluate small molecules targeting PD-L1. To this end, the relevant extracellular domain of the human gene is integrated into the locus of the mouse gene by homologous recombination (‘knock-in’). For example, the HuGEMM model for PD-1 and PD-L1 uses a human PD-1 knock-in strain that is engrafted with the mouse colon carcinoma cell line MC38 recombinantly expressing human PD-L1 [HuCELL; Crown Bioscience]. Human PD-L1 and PD-1 double knock-in animals with engraftment of MC38-huPD-L1 are developed and used to evaluate PD-L1 internalization induced by small molecules targeting PD-L1 in both tumor and host immune cells.
Example 7A. IRF3 and NF-kB Activation Assays
(2249) THP-1 Dual Cells (Invivogen) were maintained in RPMI1640 medium with addition of 10% FBS, 100 μg/ml zeocin, 10 μg/ml blasticidin. Cells were added in a 96-well flat bottom assay plate at 100,000 per well in 100 μL complete RPMI medium. Test compounds were prepared by serial dilution in complete RPMI medium and 100 μL test compounds were transferred to each corresponding well. The assay plate was incubated at 37° C., 5% CO.sub.2 for 24 hours. After the overnight incubation, 20 μL of the culture supernatants were collected, followed by addition of 180 μL of QUANTI-Blue (Invivogen) to assess IRF3 activity. The amount of IRF3 activation was assessed by reading the absorbance at 620-655 nm with a microplate reader 2 hours later. The culture supernatant from the untreated THP-1 cells was used as the negative control. EC.sub.50 determination was performed by fitting the curve of percent control activity versus the log of the compound concentration using the GraphPad Prism 6.0 software.

Example 8A and 8B. Determination of IRF3 Activation and PD-L1 Expression in HEK293T STING Reporter Cell Lines
Example 8A: Determination of IRF3 Activation in HEK293T STING Reporter Cell Lines
(2254) HEK293T STING reporter cell line was purchased from Invivogen and expressed low level of PD-L1. This cell line was then engineered at Incyte Research Institute to overexpress human PD-L1. Both PD-L1 high and PD-L1 low HEK293T cell lines were plated at 100,000 cells/100 μL/well in 10% fetal calf serum-containing DMEM culture medium in a 96-well flat bottom plate. Serial dilutions of PD-L1 small molecule-conjugated STING agonists were then added to the corresponding wells, and incubated for 20 hours at 37° C. In a competition study setting, 1 μM of a PD-L1 small molecule was added in the corresponding wells to compete with the binding of PD-L1 small molecule-conjugated STING agonists. At the end of the incubation, the culture supernatants were carefully removed from each well, and the amount of IRF3 activation was determined by adding Quanti-Blue substrate in accordance with the manufacturer's protocol. EC.sub.50's for IFR3 activation for the Example compounds were measured and are shown in Tables 5 and 7.

Example 8B: Determination of PD-L1 Surface Levels
(2256) To determine PD-L1 expression on HEK cells after treatment of PD-L1-small molecule conjugated STING agonists, cells were harvested at 20 hours post-treatment. Single cell suspensions were then stained with phycoerythrin-conjugated anti-PD-L1 antibody (BD Bioscience), and the PD-L1 expression were then analyzed by flow cytometry. Mean fluorescence intensity was used as the relative level of surface PD-L1 expression on cells (

Example 9A
(2259) In-Vitro Assay Using 293T-Dual hSTING-R232
(2260) 293T-Dual hSTING-R232 (ISG/KI-IFNb) cells that were generated from 293T-Dual Null (ISG/KI-IFNb) cells by stable transfection of the R232 isoform of human STING were purchased from Invivogen (Invivogen #293d-r232).
(2261) This cell line expresses an ISRE-inducible SEAP (secreted embryonic alkaline phosphatase) reporter construct, which monitors the activation of interferon regulatory factor (IRF) and its binding to ISRE (IFN-stimulated response elements). These reporter cells express low level of PD-L1. Human PD-L1 was then overexpressed in these cells through stable transfection.
(2262) These 293T-Dual hSTING-R232 reporter cells as well as293T-Dual hSTING-R232 reporter cells overexpressing huPD-L1 were treated with various concentrations of STING compounds for 20 hours. After 20 hours, interferon regulatory factor (IRF) activity was assessed by measuring SEAP levels in the supernatant using QUNTI-Blue. EC50 values were generated by curve fit in Prism software.
(2263) Also, cells were stained with PE-conjugated anti-human PD-L1 antibody to determine surface PD-L1 expression. Cell acquisition was performed on BD LSRFortessa X-20 (BD Biosciences). Data was analyzed using FlowJo software. IC50 values were calculated using Prism Software.
(2264) Baseline PD-L1 Expression in PBMCs and Pleural Effusion Samples by Flow Cytometry
(2265) Single cell suspension from PBMC and pleural effusions were blocked for 10 min with anti-Fc receptor antibody. The cells were then stained with different fluorochrome-conjugated antibodies for 30 minutes at room temperature to identify different cell populations. Phycoerythrin-conjugated anti-PD-L1 (clone M1H1; 12-5983-42, eBiosciences) was used to determine baseline surface PD-L1 expression on CD11b+ cells as well as HLA-DR+ cells. A commercial kit (Zombie Violet Fixable Viability Kit, Cat #423114, Biolegend) was used to exclude dead cells from data analyses. Cell acquisition was performed on BD LSRFortessa X-20 (BD Biosciences). Data was analyzed using FlowJo software.
(2266) IFN-beta Cytokine Analysis
(2267) CD11b.sup.+ cells were isolated from healthy PBMCs as well as Pleural effusion samples using Miltenyi isolation kit according to manufacturer's protocol. Cells were seeded in 96 well plates at the density of 300,000 cells/wells, and then treated with various concentrations of compounds for 20 hours. After 20 hours, IFN-beta secretion levels were evaluated in the culture supernatants by MSD singleplex assay. EC.sub.50 values were calculated using Prism software.

(2269) PD-L1 Expression on CD11b.sup.+ Monocytes Isolated from healthy PBMC and Lung Cancer Pleural Effusions
(2270) Surface PD-L1 levels on CD11b.sup.+ cells in healthy PBMCs and pleural effusion samples from lung cancer patients were determined using flow cytometry. Total of 8 healthy donors and 2 lung cancer patients were characterized (
(2271) Differential IFNβ Induction by PD-L1 Small Molecule Conjugated with STING Agonist in Healthy Donors Versus Cancer Patients
(2272) Different naked STING agonisst and PD-L1-targeted small molecule-STING agonist conjugates were added to CD11b.sup.+ monocytes cultures isolated from healthy donor blood or lung cancer patients' pleural effusions. Culture supernatants were collected 20 hours later and IFNβ production were determined using MSD singleplex assay. The EC.sub.50 values for the naked and conjugated STING agonists were summarized in Table 8. While naked STING agonists showed equivalent cellular potency in both healthy donor and patients' CD11b.sup.+ cultures, PD-L1 small molecule-STING agonist conjugates had a 3-12 fold shift in potency.
