DETAILED DESCRIPTION OF THE INVENTION

[0014] Before the present disclosure is described in greater detail, it is to be understood that this disclosure is not limited to particular embodiments described, and as such may, of course, vary. It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments only, and is not intended to be limiting, since the scope of the present disclosure will be limited only by the appended claims.

[0015] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. Although any methods and materials similar or equivalent to those described herein can also be used in the practice or testing of the present disclosure, particular methods and materials are now described.

[0016] All publications and patents cited in this specification are herein incorporated by reference as if each individual publication or patent were specifically and individually indicated to be incorporated by reference and are incorporated herein by reference to disclose and describe the methods and/or materials in connection with which the publications are cited. The citation of any publication is for its disclosure prior to the filing date and should not be construed as an admission that the present disclosure is not entitled to antedate such publication by virtue of prior disclosure. Further, the dates of publication provided could be different from the actual publication dates that may need to be independently confirmed.

[0017] As will be apparent to those of skill in the art upon reading this disclosure, each of the individual embodiments described and illustrated herein has discrete components and features which may be readily separated from or combined with the features of any of the other several embodiments without departing from the scope or spirit of the present disclosure. Any recited method can be carried out in the order of events recited or in any other order that is logically possible.

[0018] Embodiments of the present disclosure will employ, unless otherwise indicated, techniques of medicine, organic chemistry, biochemistry, molecular biology, pharmacology, and the like, which are within the skill of the art. Such techniques are explained fully in the literature.

[0019] It must be noted that, as used in the specification and the appended claims, the singular forms a, an, and the include plural referents unless the context clearly dictates otherwise.

[0020] With regard to chemical structure, it is understood that claiming compounds that are racemic encompasses all of the isomers, tautomers, enantiomers, or diastereomers unless otherwise specified to be a composition of excess of a specific isomer. For instance, an isomer/enantiomer can, in some embodiments, be provided substantially free of the corresponding enantiomer, and can also be referred to as optically enriched, enantiomerically enriched, enantiomerically pure and non-racemic, as used interchangeably herein. These terms refer to compositions in which the amount of one enantiomer is greater than the amount of that one enantiomer in a control mixture of the racemic composition (e.g., greater than 1:1 by weight). For example, an enantiomerically enriched preparation of the S enantiomer, means a preparation of the compound having greater than about 50% by weight of the S enantiomer relative to the total weight of the preparation (e.g., total weight of S and R isomers) such as at least about 75% by weight, further such as at least about 80% by weight. In some embodiments, the enrichment can be much greater than about 80% by weight, providing a substantially enantiomerically enriched, substantially enantiomerically pure or a substantially non-racemic preparation, which refers to preparations of compositions which have at least about 85% by weight of one enantiomer relative to the total weight of the preparation, such as at least about 90% by weight, and further such as at least about 95% by weight. In certain embodiments, the compound provided herein is made up of at least about 90% by weight of one enantiomer. In other embodiments, the compound is made up of at least about 95%, about 98%, or about 99% by weight of one enantiomer.

[0021] In certain embodiments, the pharmaceutically acceptable form is a tautomer. As used herein, the term tautomer is a type of isomer that includes two or more interconvertable compounds resulting from at least one formal migration of a hydrogen atom and at least one change in valency (e.g., a single bond to a double bond, a triple bond to a double bond, or a triple bond to a single bond, or vice versa). Tautomerization includes prototropic or proton-shift tautomerization, which is considered a subset of acid-base chemistry. Prototropic tautomerization or proton-shift tautomerization involves the migration of a proton accompanied by changes in bond order. The exact ratio of the tautomers depends on several factors, including temperature, solvent, and pH. Where tautomerization is possible (e.g., in solution), a chemical equilibrium of tautomers can be reached. Tautomerizations (i.e., the reaction providing a tautomeric pair) can be catalyzed by acid or base, or can occur without the action or presence of an external agent. Exemplary tautomerizations include, but are not limited to, keto-enol; amide-imide; lactam-lactim; enamine-imine; and enamine-(a different) enamine tautomerizations. A specific example of keto-enol tautomerization is the interconversion of pentane-2,4-dione and 4-hydroxypent-3-en-2-one tautomers. Another example of tautomerization is phenol-keto tautomerization. A specific example of phenol-keto tautomerization is the interconversion of pyridin-4-ol and pyridin-4(1H)-one tautomers.

[0022] The disclosure also embraces isotopically labeled compounds which are identical to those recited herein, except that one or more atoms are replaced by an atom having an atomic mass or mass number different from the atomic mass or mass number usually found in nature. Examples of isotopes that can be incorporated into disclosed compounds include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorus, sulfur, fluorine, and chlorine, such as, e.g., .sup.2H, .sup.3H, .sup.13C, .sup.14C, .sup.15N, .sup.18O, .sup.17O, .sup.31P, .sup.32P, .sup.35S, .sup.18F, and .sup.36Cl, respectively. Certain isotopically-labeled disclosed compounds (e.g., those labeled with .sup.3H and/or .sup.14C) are useful in compound and/or substrate tissue distribution assays. Tritiated (i.e., .sup.3H) and carbon-14 (i.e., .sup.14C) isotopes can allow for ease of preparation and detectability. Further, substitution with heavier isotopes such as deuterium (i.e., .sup.2H) can afford certain therapeutic advantages resulting from greater metabolic stability (e.g., increased in vivo half-life or reduced dosage requirements). Isotopically labeled disclosed compounds can generally be prepared by substituting an isotopically labeled reagent for a non-isotopically labeled reagent. In some embodiments, provided herein are compounds that can also contain unnatural proportions of atomic isotopes at one or more of atoms that constitute such compounds. All isotopic variations of the compounds as disclosed herein, whether radioactive or not, are encompassed within the scope of the present disclosure.

[0023] The term prodrug refers any covalently bonded carriers, which release the active compound in vivo when such prodrug is administered to a subject. Prodrugs of an active compound, as described herein, can be prepared by modifying functional groups present in the active compound in such a way that the modifications are cleaved, either in routine manipulation or in vivo, to the parent active compound. Prodrugs include compounds wherein a carboxyl, hydroxy, amino or mercapto group is bonded to any group that, when the prodrug of the active compound is administered to a subject, cleaves to form a free hydroxy, free carboxyl, free amino or free mercapto group, respectively. Examples of prodrugs include, but are not limited to, carboxyl esters, acetate, formate and benzoate derivatives of an alcohol or acetamide, formamide and benzamide derivatives of an amine functional group in the active compound and the like.

[0024] The term ester refers to esters of acidic groups, including, but not limited to, carboxylic acids, phosphoric acids, phosphinic acids, sulfonic acids, sulfinic acids, and boronic acids, e.g., a radical of formula COOR, where R is selected from alkyl, alkenyl, alkynyl, haloalkyl, heteroalkyl (bonded through a chain carbon), cycloalkyl, cycloalkylalkyl, aryl, aralkyl, heterocycloalkyl (bonded through a ring carbon), heterocycloalkylalkyl, heteroaryl (bonded through a ring carbon), and heteroarylalkyl. Any amine, hydroxy, or carboxyl side chain on the compounds described herein can be esterified. The procedures and specific groups to make such esters are known to those of skill in the art and can readily be found in reference sources such as Greene and Wuts, Protective Groups in Organic Synthesis, 4th Ed., John Wiley & Sons, New York, N.Y., 2006, which is incorporated herein by reference in its entirety.

In another aspect, provided herein is a method of treating or ameliorating one or more symptoms associated with a cancer in a subject in need thereof, including administering to the subject a therapeutically effective amount of a compound or composition disclosed herein.

[0059] Within the context of certain embodiments, whether cancer is reduced may be identified by a variety of diagnostic manners known to one skill in the art including, but not limited to, observation the reduction in size or number of tumor masses or if an increase of apoptosis of cancer cells observed, e.g., if more than a 5% increase in apoptosis of cancer cells is observed for a sample compound compared to a control without the compound. It may also be identified by a change in relevant biomarker or gene expression profile, such as PSA for prostate cancer, HER2 for breast cancer, or others.

[0060] The effective amount of the present compounds depend on many factors, including the indication being treated, the route of administration, co-administration of other therapeutic compositions, and the overall condition of the patient.

[0061] In general, treatment regimens utilizing compounds include administration of from about 0.1 mg to about 300 mg of the compounds per kilogram body weight of the recipient per day in multiple doses or in a single dose. In some embodiments, a suitable dose may be in the range of 0.1 to 300 mg per kilogram body weight of the recipient per day, optionally in the range of 6 to 150 mg per kilogram body weight per day, optionally in the range of 15 to 100 mg per kilogram body weight per day, optionally in the range of 15 to 80 mg per kilogram body weight per day, optionally in the range of 15 to 50 mg per kilogram body weight per day, and optionally in the range of 15 to 30 mg per kilogram body weight per day. The desired dose may be presented as two, three, four, five or six or more sub-doses administered at appropriate intervals throughout the day. These sub-doses may be administered in unit dosage forms, for example, containing 10 to 2000 mg, optionally 10 to 1500 mg, optionally 20 to 1000 mg, and optionally 50 to 700 mg of the compounds per unit dosage form.

For example, the compounds and/or their pharmaceutically acceptable salts can be administered in the form of a pharmaceutical composition in association with one or more pharmaceutically acceptable excipients, such as the pharmaceutical compositions described below. The choice of the pharmaceutically acceptable excipients will to a large extent depend on factors such as the particular mode of administration, the effect of the excipient on solubility and stability, and the nature of the dosage form. The cancer to be treated or reduced or the symptoms associated with the cancer to be treated or ameliorated in the context of the present disclosure may be any type of cancer or tumor.

[0063] In an embodiment, the tumors or cancer include, and are not limited to, tumors of the hematopoietic and lymphoid tissues or hematopoietic and lymphoid malignancies, tumors that affect the blood, bone marrow, lymph, and lymphatic system. Hematological malignancies may derive from either of the two major blood cell lineages: myeloid and lymphoid cell lines. The myeloid cell line normally produces granulocytes, erythrocytes, thrombocytes, macrophages and mast cells; the lymphoid cell line produces B, T, NK and plasma cells. Lymphomas, lymphocytic leukemias, and myeloma are from the lymphoid line, while acute and chronic myelogenous leukemia, myelodysplastic syndromes and myeloproliferative diseases are myeloid in origin.

[0315] In certain embodiment, this disclosure contemplates pharmaceutical compositions containing compounds disclosed herein in a pharmaceutically acceptable form. In certain embodiment, this disclosure contemplates pharmaceutical compositions containing compounds disclosed herein in a pharmaceutically acceptable form and pharmaceutically acceptable excipient. In certain embodiments, this disclosure contemplates the production of a medicament containing compounds disclosed herein and uses for methods disclosed herein.

[0316] As used herein, a pharmaceutically acceptable form of a disclosed compound includes, but is not limited to, pharmaceutically acceptable salts, hydrates, solvates, isomers, prodrugs, and isotopically labeled derivatives of disclosed compounds. In one embodiment, a pharmaceutically acceptable form includes, but is not limited to, pharmaceutically acceptable salts of disclosed compounds.

[0317] In certain embodiments, the pharmaceutically acceptable form is a pharmaceutically acceptable salt. As used herein, the term pharmaceutically acceptable salt refers to those salts which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of subjects without undue toxicity, irritation, allergic response and the like, and are commensurate with a reasonable benefit/risk ratio. Pharmaceutically acceptable salts are well known in the art. For example, Berge et al. describes pharmaceutically acceptable salts in detail in J. Pharmaceutical Sciences (1977) 66:1-19. Pharmaceutically acceptable salts of the compounds provided herein include those derived from suitable inorganic and organic acids and bases. Examples of pharmaceutically acceptable, nontoxic acid addition salts are salts of an amino group formed with inorganic acids such as hydrochloric acid, hydrobromic acid, phosphoric acid, sulfuric acid and perchloric acid or with organic acids such as acetic acid, oxalic acid, maleic acid, tartaric acid, citric acid, succinic acid or malonic acid or by using other methods used in the art such as ion exchange. Other pharmaceutically acceptable salts include adipate, alginate, ascorbate, aspartate, benzenesulfonate, besylate, benzoate, bisulfate, borate, butyrate, camphorate, camphorsulfonate, citrate, cyclopentanepropionate, digluconate, dodecylsulfate, ethanesulfonate, formate, fumarate, glucoheptonate, glycerophosphate, gluconate, hemisulfate, heptanoate, hexanoate, hydroiodide, 2-hydroxy-ethanesulfonate, lactobionate, lactate, laurate, lauryl sulfate, malate, maleate, malonate, methanesulfonate, 2-naphthalenesulfonate, naphthalene-m,n-bissulfonates, nicotinate, nitrate, oleate, oxalate, palmitate, pamoate, pectinate, persulfate, 3-phenylpropionate, phosphate, picrate, pivalate, propionate, stearate, succinate, sulfate, tartrate, thiocyanate, p-toluenesulfonate, undecanoate, valerate salts, and the like. In some embodiments, organic acids from which salts can be derived include, for example, acetic acid, propionic acid, glycolic acid, pyruvic acid, oxalic acid, maleic acid, malonic acid, succinic acid, fumaric acid, tartaric acid, citric acid, benzoic acid, cinnamic acid, mandelic acid, methanesulfonic acid, ethanesulfonic acid, p-toluenesulfonic acid, salicylic acid, naphthalene-m,n-bissulfonic acids and the like.

[0318] Pharmaceutically acceptable salts derived from appropriate bases include alkali metal, alkaline earth metal, ammonium and quaternary ammonium, e.g., N.sup.+(R).sub.4, salts. Representative alkali or alkaline earth metal salts include sodium, lithium, potassium, calcium, magnesium, iron, zinc, copper, manganese, aluminum, and the like. Further pharmaceutically acceptable salts include, when appropriate, nontoxic ammonium, quaternary ammonium, and amine cations formed using counterions such as halide, hydroxide, carboxylate, sulfate, phosphate, nitrate, lower alkyl sulfonate, and aryl sulfonate. Organic bases from which salts can be derived include, for example, primary, secondary, and tertiary amines, substituted amines including naturally occurring substituted amines, cyclic amines, basic ion exchange resins, and the like, such as isopropylamine, trimethylamine, diethylamine, triethylamine, tripropylamine, and ethanolamine. In some embodiments, the pharmaceutically acceptable base addition salt is chosen from ammonium, potassium, sodium, calcium, and magnesium salts.

[0319] In certain embodiments, the pharmaceutically acceptable form is a solvate (e.g., a hydrate). As used herein, the term solvate refers to compounds that further include a stoichiometric or non-stoichiometric amount of solvent bound by non-covalent intermolecular forces. The solvate can be of a disclosed compound or a pharmaceutically acceptable salt thereof. Where the solvent is water, the solvate is a hydrate. Pharmaceutically acceptable solvates and hydrates are complexes that, for example, can include 1 to about 100, or 1 to about 10, or one to about 2, about 3 or about 4, solvent or water molecules. It will be understood that the term compound as used herein encompasses the compound and solvates of the compound, as well as mixtures thereof.

[0320] Pharmaceutical compositions typically contain an effective amount of compounds and a suitable pharmaceutically acceptable carrier. The preparations can be prepared in a manner known per se, which usually involves mixing the compounds according to the disclosure with the one or more pharmaceutically acceptable carriers, and, if desired, in combination with other pharmaceutical active compounds, when necessary under aseptic conditions.

[0321] In certain embodiments, the disclosure relates to pharmaceutical compositions containing compounds disclosed herein and a pharmaceutically acceptable excipient. In certain embodiments, the composition is a pill, tablet, gel, granule, or in a capsule or the composition is an aqueous phosphate buffer, e.g., isotonic solution with a pH between 6 and 8. In certain embodiments, the pharmaceutically acceptable excipient is selected from a filler, glidant, binder, disintegrant, lubricant, and saccharide.

[0322] Compositions suitable for parenteral injection may contain physiologically acceptable sterile aqueous or nonaqueous solutions, dispersions, suspensions or emulsions, and sterile powders for reconstitution into sterile injectable solutions or dispersions. Examples of suitable aqueous and nonaqueous carriers, diluents solvents or vehicles include water, ethanol, polyols (propylene glycol, polyethylene glycol, glycerol, and the like), suitable mixtures thereof, vegetable (such as olive oil, sesame oil and viscoleo) and injectable organic esters such as ethyl oleate.

[0323] Prevention of the action of microorganisms may be controlled by addition of any of various antibacterial and antifungal agents, example, parabens, chlorobutanol, phenol, sorbic acid, and the like. It may also be desirable to include isotonic agents, for example sugars, sodium chloride, and the like. Prolonged absorption of the injectable pharmaceutical form can be brought about by the use of agents delaying absorption, for example, aluminum monostearate and gelatin.

[0324] Solid dosage forms for oral administration include capsules, tablets, pills, powders and granules. In such solid dosage forms, the compounds may be admixed with at least one inert customary excipient (or carrier) such as sodium citrate or dicalcium phosphate or: (a) fillers or extenders, as for example, starches, lactose, sucrose, glucose, mannitol and silicic acid, (b) binders, as for example, carboxymethylcellulose, alginates, gelatin, polyvinylpyrrolidone, sucrose, and acacia, (c) humectants, as for example, glycerol (d) disintegrating agents, as for example, agar-agar, calcium carbonate, potato or tapioca starch, alginic acid, certain complex silicates, and sodium carbonate, (e) solution retarders, as for example paraffin, (f) absorption accelerators, as for example, quaternary ammonium compounds, (g) wetting agents, as for example cetyl alcohol, and glycerol monostearate, (h) adsorbents, as for example, kaolin and bentonite, and (i) lubricants, as for example, talc, calcium stearate, magnesium stearate, solid polyethylene glycols, sodium lauryl sulfate, or mixtures thereof. In the case of capsules, tablets, and pills, the dosage forms may also comprise buffering agents.

[0325] Liquid dosage forms for oral administration include pharmaceutically acceptable emulsions, solutions, suspensions, syrups, and elixirs. In addition to the compounds, the liquid dosage forms may contain inert diluents commonly used in the art, such as water or other solvents, solubilizing agents and emulsifiers, for example, ethyl alcohol, isopropyl alcohol, ethyl carbonate, ethyl acetate, benzyl alcohol, benzyl benzoate, propylene glycol, 1,3-butylene glycol, dimethylformamide, oils, in particular, cottonseed oil, groundnut oil, corn germ oil, olive oil, viscoleo, castor oil and sesame oil, glycerol, tetrahydrofurfuryl alcohol, polyethyleneglycols and fatty acid esters of sorbitan or mixtures of these substances, and the like.

[0326] In certain embodiments, production processes are contemplated which two components, compounds disclosed herein and a pharmaceutical carrier, are provided already in a combined dry form ready to be reconstituted together. In other embodiments, it is contemplated that compounds disclosed herein and a pharmaceutical carrier are admixed to provide a pharmaceutical composition.

[0327] Providing a pharmaceutic composition is possible in a one-step process, simply by adding a suitable pharmaceutically acceptable diluent to the composition in a container. In certain embodiments, the container is preferably a syringe for administering the reconstituted pharmaceutical composition after contact with the diluent. In certain embodiments, the coated compounds can be filled into a syringe, and the syringe can then be closed with the stopper. A diluent is used in an amount to achieve the desired end-concentration. The pharmaceutical composition may contain other useful component, such as ions, buffers, excipients, stabilizers, etc.

[0328] A dry pharmaceutical composition typically has only a residual content of moisture, which may approximately correspond to the moisture content of comparable commercial products, for example, has about 12% moisture as a dry product. Usually, the dry pharmaceutical composition according to the present invention has a residual moisture content preferably below 10% moisture, more preferred below 5% moisture, especially below 1% moisture. The pharmaceutical composition can also have lower moisture content, e.g. 0.1% or even below. In certain embodiments, the pharmaceutical composition is provided in dry in order to prevent degradation and enable storage stability.

[0329] A container can be any container suitable for housing (and storing) pharmaceutically compositions such as syringes, vials, tubes, etc. The pharmaceutical composition may then preferably be applied via specific needles of the syringe or via suitable catheters. A typical diluent comprises water for injection, and NaCl (preferably 50 to 150 mM, especially 110 mM), CaCl.sub.2 (preferably 10 to 80 mM, especially 40 mM), sodium acetate (preferably 0 to 50 mM, especially 20 mM) and mannitol (preferably up to 10% w/w, especially 2% w/w). Preferably, the diluent can also include a buffer or buffer system so as to buffer the pH of the reconstituted dry composition, preferably at a pH of 6.2 to 7.5, especially at pH of 6.9 to 7.1.

[0330] In certain embodiments, the diluent is provided in a separate container. This can preferably be a syringe. The diluent in the syringe can then easily be applied to the container for reconstitution of the dry compositions. If the container is also a syringe, both syringes can be finished together in a pack. It is therefore preferred to provide the dry compositions in a syringe, which is finished with a diluent syringe with a pharmaceutically acceptable diluent for reconstituting, said dry and stable composition.

[0331] In certain embodiments, this disclosure contemplates a kit containing a pharmaceutical composition disclosed herein and a container with a suitable diluent. Further components of the kit may be instructions for use, administration means, such as syringes, catheters, brushes, etc. (if the compositions are not already provided in the administration means) or other components necessary for use in medical (surgical) practice, such as substitute needles or catheters, extra vials or further wound cover means. In certain embodiments, the kit contains a syringe housing the dry and stable hemostatic composition and a syringe containing the diluent (or provided to take up the diluent from another diluent container).

Molecular Modeling to Synthesize MX69 Analogs

[0332] MX69 was selected for further drug development (Gu et al. Cancer Cell. 2016, 30(4):623-636). MX69 is a protein-binding compound that specifically binds to the RING domain of MDM2 and has minimal toxicity on normal cells/tissues (which typically do not express MDM2). It is desirable to identify improved anticancer potency with better PK/PD profiles. FIGS. 1 and 2 illustrate compounds and general methods of preparations.

[0491] Identification of MX69 Analogs with Increased MDM2 Binding Affinity.

[0492] Materials and Methods

[0493] Cell Lines and Cell Culture

[0494] This study used two ALL cell lines (EU-1 and EU-3) and three NB cell lines (NB-1643, SHEP1 and LA1-55N). All 5 cancer cell lines were established from pediatric ALL or NB patients and were well-characterized for their expression of MDM2 and p53-status, as reported previously. All cell lines were grown in standard culture medium (RPMI 1640 containing 10% FBS, 2 mmol/L L-glutamine, 50 U penicillin and 50 g/mL streptomycin) at 37 C. in a humidified atmosphere containing 5% CO.sub.2.

[0495] Immunoprecipitation and Western Blot Assay

[0496] Cells were lysed in a buffer composed of 50 mM Tris, pH 7.6, 150 mM NaCl, 1% Nonidet P-40, 10 mM sodium phosphate, 10 mM NaF, 1 mM sodium orthovanadate, 2 mM phenylmethylsulfonyl fluoride (PMSF), 10 g/mL aprotinin, 10 g/mL leupeptin and 10 g/mL pepstatin. After centrifugation, the clarified cell lysate was separated from the pellet of cell debris, and then incubated with 15 L Protein G/Protein A-agarose and 1 g of antibodies, overnight at 4 C. For the Western blot, the resulting cell lysates or immunoprecipitates were resolved by SDS-PAGE. They were then transferred to a nitrocellulose filter and probed with the specific antibodies as listed in the supplemental Materials section. Finally, proteins were visualized with a chemiluminescent detection system.

[0497] Pulse-Chase Assay

[0498] Protein turnover was assessed by a standard protein-synthesis inhibitor (CHX) assay. Briefly, cells were treated with 50 g/mL CHX for different times before lysis, in the presence or absence of AQ-101, and then tested by Western blot analysis to reveal concurrent expression levels of MDM2, p53 and XIAP. The mRNA degradation rate was examined using a standard actinomycin D analysis: At different times after addition of 5 g/mL of actinomycin D, in the presence or absence of AQ-101, the cells were harvested and their total RNA isolated. The MDM2 mRNA was detected by quantitative RT-PCR, as described above.

[0499] Compound-Protein Binding Assays

[0500] Isothermal titration calorimetry (ITC) assay was performed using the auto-iTC200 instrument (MicroCal, GE). MDM2 protein was loaded into a 96 DeepWell PP plate, and then compound was titrated stepwise into the protein sample cell using a syringe, for a total of 16 injections (except for the first injection, which was 0.4 l). The equilibrium time between two adjacent injections was 210 s. The binding stoichiometry (n), binding constant (Kd), and thermodynamic parameters (H and S) were determined by fitting the titration curve to a one-site binding mode, using the Origin software provided by the manufacturer.

[0501] Polysome Preparation and Analysis

[0502] Cells were incubated with 100 g/mL cycloheximide (CHX) for 15 min to arrest polyribosome migration, and then lysed (in order to isolate cytoplasmic extracts) in a buffer containing 20 mM Tris-HCl at pH 8.0, 100 mM NaCl, 5 mM MgCl.sub.2, 0.5% Triton X-100, 500 U/mL RNAsin, and a cocktail of protease inhibitors. Fractionation was performed on a 15-45% (w/v) sucrose gradient at 39,000 rpm for 1 h (SW41Ti rotor). Fractions were collected by upward replacement in a fractionator (Isco, Lincoln, NE). The RNA from each fraction was subjected to quantitative PCR.

[0503] Clonogenic Assay

[0504] A clonogenic assay was used to determine the effect of MX69 analogs on in vitro growth of NB and normal human hematopoietic cells, respectively. For NB1 colony formation assay, cells were harvested with treatment by trypsinization, producing a single-cell suspension, and then 200 cells were seeded into a 6-well plate and cultured for approximately 2 weeks. Colonies were stained with a mixture of 6.0% glutaraldehyde and 0.5% crystal violet for 30 min. Then carefully removed the staining mixture, rinsed with tap water and counted the colonies.

[0505] For colony formation of normal human hematopoiesis assay, a bottom layer of low-melting-point, 0.5% agarose (in RPMI 1640 medium plus 10% FBS) was poured into gridded 35 mm dishes and allowed to gel. Cells were cultured in a top layer of 0.35% agarose/medium at 37 C. in a humidified atmosphere containing 5% CO.sub.2. After 2-3 weeks, cultures were fixed with formalin and colonies scored.

[0506] Cytotoxicity Assay

[0507] The cytotoxic effect of MX 69 and MX69 analogs on cancer cells was determined using the water-soluble tetrazolium salt (WST) assay. Briefly, cells cultured in 96-well microtiter plates were treated with different concentrations of AQ-101 for a 20-h period. WST (25 g/well) was then added and incubation continued for an additional 4 h, after which optical density (OD) was read with a microplate reader (test wavelength of 450 nm; reference wavelength of 620 nm).

[0508] Results

[0509] Both 69L52 and 69L53 have Increased MDM2 Binding Affinity

[0510] MX69 has been detected to bind to the MDM2 C-terminal RING protein. To confirm that the new analogs with improved potency maintain this mode of action, isothermal titration calorimetry (ITC) assays were performed. Both 69L52 and 53 bind to the MDM2 RING domain with increased binding affinities as compared with MX69 (FIG. 3).

[0511] Compound 69L52 Attenuates the Proliferation in Cancer Cells but Shows a Negligible Inhibitory Effect on Normal Hematopoiesis.

[0512] Five cancer cell lines were tested including two acute lymphoblastic (ALL) EU-1 and EU-3 and three neuroblastoma (NB) NB-1643, SHEP1 and LA1-55N in response to 69L52. WST cytotoxicity assays show that 69L52 consistently exhibited potent cytotoxicity against these tested cell lines with more sensitive of ALL (IC.sub.50=0.30.4 M) than NB (IC.sub.50=0.51.2 M) to 69L52 (FIG. 4A). As also seen in FIG. 4A, the much less cytotoxicity to NB line LA1-55N compared with other cell lines by compound 69L52 mostly likely because this line does not express normal p53 as characterized in our previous publication. Furthermore, results of colony formation assays showed that 69L52 potently inhibited cell growth in all 3 NB cell lines. A significant reduction in both colony number and size in 69L52-treated cells was observed as compared with controls (FIG. 4B).

[0513] To evaluate the possible inhibitory and toxic effect of 69L52 on normal hematopoiesis, clonogenic assays for CFU-GM and BFU-E were preformed using human normal bone marrow mononuclear (NBMM) cells, with doxorubicin (Dox) as a reference control. CFU-GM and BFU-E colony numbers and size in 69L52-treated samples were similar to the control, whereas both colony number and size were significantly reduced in the Dox-treated samples (FIGS. 4C and 4D).

[0514] Compound 69L52 Inhibits Expression of MDM2 Through Post-Translational Modification.

[0515] Western blot assays were performed for effects of 69L52 on MDM2 and XIAP expression. Results show that 69L52 induced a remarkable downregulation of MDM2 and XIAP in a dose-dependent manner and occurred at approximately 2-4 h after treatment, followed by steady-state suppression (FIG. 5A). Downregulation of MDM2 was accompanied by increased expression of p53. To further evaluate the mechanism by which 69L52 inhibits MDM2, MG132 (protein degradation inhibitor) treatment and cycloheximide (CHX) chase assays in EU-1 cells treated with 69L52 were performed; results show that 69L52 induced increased MDM2 protein degradation. As shown in FIG. 5B, the observed downregulation of MDM2 by 69L52 was blocked by MG132. CHX chase assay results showed that the half-life of MDM2 in untreated EU-1 cells was >120 min, whereas 69L52 treatment decreased the MDM2 half-life to <60 min (FIG. 5C). In contrast, the half-life of p53 in untreated cells was <30 min, and the time was increased to >120 min by treatment with 69L52. Since MDM2 protein stability is regulated by a self-ubiquitination mechanism, whether 69L52 induced MDM2-protein degradation is mediated through this mechanism was tested. Immunoprecipitation (IP)-Western blot assays were preformed and results show that 69L52 induced ubiquitination of endogenous MDM2 in EU-1 cells (FIG. 5D). These results show that 69L52 downregulates MDM2 through induction of MDM2 self-ubiquitination and degradation. Furthermore, activation of p53 following 69L52-mediated MDM2 ubiquitination and degradation led to activation of the p53 downstream targets p21 and PUMA (FIG. 5E).

[0516] Compound 69L52 Inhibits XIAP Translation and Activity.

[0517] Linear sucrose-gradient fractionation was performed to assess the state of polyribosome association of XIAP mRNA in EU-1 cells subjected to 69L52 treatment. 69L52 induced a downregulation in polyribosome association. This was shown by a shift in XIAP mRNA from fractions containing enriched translating polyribosomes to fractions containing translation-inactive complexes monoribosomes (FIG. 6A). The effects of 69L52 mediated inhibition of XIAP on activation of caspases-3 and -9 were also tested, as well as cleavage of the death substrate PARP. As shown in FIG. 6B, cleavage of caspases-3, -9, and PARP can be detected 8 h after McX69-102 treatment in EU-1 cells. Simultaneously, EU-1 cells were treated with MX69 as comparison, and results show that 69L52 induced stronger cleavage of caspases-3, -9 and PARP at a much lower dose (1 M) than MX69 (5 M). These demonstrate that the increased potency of 69L52 than MX69 in inhibiting EU-1 cells is closely associated with the enhanced inhibition of XIAP function as well as activation of p53.
