Description

[0001] This application is a divisional application of the invention patent application with application date of January 9, 2023, application number 202380026429.5, and invention name “RAS inhibitor”.

[0002] CROSS-REFERENCE TO RELATED APPLICATIONS

[0003] This application claims the benefit of priority to U.S. application No. 63 / 298,098, filed on January 10, 2022, all of which are hereby incorporated by reference in their entirety. Background Art

[0004] The vast majority of small molecule drugs work by binding to functionally important pockets on target proteins, thereby regulating the activity of the protein. For example, cholesterol-lowering drugs known as statins bind to the enzymatic active site of HMG-CoA reductase, thereby preventing the enzyme from engaging its substrate. The fact that many such drug / target interaction pairs are known may mislead some people into believing that small molecule regulators for most (if not all) proteins can be found, which provides a reasonable amount of time, effort and resources. But this is far from the case. Currently, it is estimated that only about 10% of all human proteins can be targeted by small molecules. Bojadzic and Buchwald, Curr Top Med Chem 18: 674-699 (2019). The other 90% are currently considered to be difficult to treat or difficult to handle for the above-mentioned small molecule drug discovery. Such targets are often referred to as "undruggable". These undruggable targets include a huge and largely untapped reservoir of medically important human proteins. Therefore, there is great interest in discovering new molecular modalities that can regulate the functions of such undruggable targets.

[0005] It is well established in the literature that Ras proteins (K-Ras, H-Ras, and N-Ras) play a crucial role in a variety of human cancers and are therefore suitable targets for anticancer therapy. In fact, in the United States, approximately 30% of all human cancers are caused by mutations in Ras proteins, many of which are lethal. Ras protein dysregulation caused by activating mutations, overexpression, or upstream activation is common in human tumors, and activating mutations in Ras are frequently found in human cancers. For example, activating mutations at codon 12 in Ras proteins act by inhibiting GTPase activating protein (GAP) dependency and intrinsic GTP hydrolysis rate, significantly biasing the Ras mutant protein population toward the "on" (GTP-bound) state (Ras(ON)), leading to oncogenic MAPK signaling. Notably, Ras exhibits a picomolar affinity for GTP and can be activated even in the presence of low concentrations of this nucleotide. Mutations at codon 13 (eg, G13C) and codon 61 (eg, Q61K) in Ras also cause oncogenic activity in some cancers.

[0006] Despite extensive drug discovery efforts targeting Ras over the past few decades, only two agents targeting the K-Ras G12C mutant (sotorasib and adagrasib) have been approved in the U.S. Additional efforts are needed to discover additional drugs for cancers driven by various Ras mutations. Summary of the Invention

[0007] Ras inhibitors are provided herein. The methods described herein require the formation of a high-affinity three-component complex between a synthetic ligand and two intracellular proteins that do not interact under normal physiological conditions: a target protein of interest (e.g., Ras), and a cytoplasmic chaperone protein (presenting protein) (e.g., cyclophilin A) that is widely expressed in cells. More specifically, in some embodiments, the Ras inhibitors described herein induce new binding pockets in Ras by driving the formation of a high-affinity ternary complex or conjugate between the Ras protein and the widely expressed cytoplasmic chaperone protein cyclophilin A (CYPA). Without being bound by theory, the inventors believe that one way in which the compounds of the present invention and the complexes or conjugates formed therefrom exert an inhibitory effect on Ras is to spatially block the interaction sites between Ras and downstream effector molecules such as RAF and PI3K required to propagate oncogenic signals.

[0097] Compound

[0098] Ras inhibitors are provided herein. The methods described herein require the formation of a high-affinity three-component complex between a synthetic ligand and two intracellular proteins that do not interact under normal physiological conditions: a target protein of interest (e.g., Ras), and a cytoplasmic chaperone protein (presenting protein) (e.g., cyclophilin A) that is widely expressed in cells. More specifically, in some embodiments, the Ras inhibitors described herein induce new binding pockets in Ras by driving the formation of a high-affinity triple complex between the Ras protein and the widely expressed cytoplasmic chaperone protein cyclophilin A (CYPA). Without being bound by theory, the inventors believe that one way in which the compounds of the present invention and the complexes or conjugates formed therefrom exert an inhibitory effect on Ras is to spatially block the interaction sites between Ras and downstream effector molecules, such as RAF, required for propagating oncogenic signals.

[0099] Without being bound by theory, the inventors assume that the covalent and non-covalent interactions of the compounds of the present invention with Ras and chaperone proteins (e.g., cyclophilin A) can contribute to the inhibition of Ras activity. In some embodiments, the compounds of the present invention form covalent adducts with the side chains of Ras proteins (e.g., the sulfhydryl side chains of cysteine ​​at positions 12 or 13 of mutant Ras proteins). Covalent adducts can also be formed with other side chains of Ras. Additionally or alternatively, non-covalent interactions can play a role: for example, van der Waals interactions, hydrophobic interactions, hydrophilic interactions, and hydrogen bond interactions and combinations thereof can contribute to the ability of the compounds of the present invention to form complexes and act as Ras inhibitors. Therefore, the compounds of the present invention can inhibit a variety of Ras proteins (e.g., K-Ras, N-Ras, H-Ras, and mutants thereof mutated at positions 12, 13, and 61, such as G12C, G12D, G12V, G12S, G13C, G13D, and Q61L, as well as other mutants described herein).

[0100] Methods of determining covalent adduct formation are known in the art.One method of determining covalent adduct formation is to perform a "cross-linking" assay, such as that performed under these conditions.

[0101] Note: The following protocol describes a procedure for monitoring the cross-linking of K-Ras G12C (GMP-PNP) with compounds of the invention. This protocol can also be implemented by substituting other Ras proteins or nucleotides such as G13C.

[0102] The purpose of this biochemical assay is to measure the ability of a test compound to covalently label a nucleotide-loaded K-Ras isoform. A 5 μM stock solution of K-Ras (1-169) G12C loaded with GMP-PNP is diluted 10-fold to a final concentration of 0.5 μM in an assay buffer containing 12.5 mM HEPES pH 7.4, 75 mM NaCl, 1 mM MgCl2, 1 mM BME, 5 μM cyclophilin A, and 2 μM test compound; the final sample volume is 100 μL.

[0103] The samples were incubated at 25°C for up to 24 hours, after which they were quenched by adding 10 μL of 5% formic acid. The quenched samples were centrifuged at 15,000 rpm for 15 minutes in a benchtop centrifuge, after which a 10 μL aliquot was injected onto a reverse-phase C4 column and eluted into the mass spectrometer using an increasing acetonitrile gradient as the mobile phase. Raw data were analyzed using Waters MassLynx MS software, where % binding was calculated from the deconvoluted protein peaks of labeled and unlabeled K-Ras.

[0562] The compounds described herein can be prepared from commercially available starting materials or synthesized using known organic, inorganic, or enzymatic techniques.

[0563] The compounds of the present invention can be prepared in a variety of ways well known to those skilled in the art of organic synthesis. For example, the compounds of the present invention can be synthesized using the methods described in the following schemes, as well as synthetic methods known in the field of synthetic organic chemistry or modifications thereof as understood by those skilled in the art. These methods include, but are not limited to, the methods described in the following schemes.

[0564] Scheme 1. General synthesis of macrocyclic esters

[0565]

[0566] The general synthesis of macrocyclic esters is outlined in Scheme 1. Appropriately substituted aryl-3-(5-bromo-1-ethyl-1H-indol-3-yl)-2,2-dimethylpropan-1-ols (1) can be prepared starting from protected 3-(5-bromo-2-iodo-1H-indol-3-yl)-2,2-dimethylpropan-1-ol and an appropriately substituted boronic acid in a three-step process involving palladium-mediated coupling, alkylation, and deprotection. Amino-hexahydropyridazine-3-carboxylic acid methyl ester-boronic acid esters (2) can be prepared in a three-step process involving protection, iridium catalyst-mediated borylation, and coupling with (S)-hexahydropyridazine-3-carboxylic acid methyl ester.

[0567] Appropriately substituted acetylpyrrolidine-3-carbonyl-N-methyl-L-valine (or alternative amino acid derivatives) (4) can be prepared by coupling methyl-L-valine ester with protected (S)-pyrrolidine-3-carboxylic acid, followed by deprotection, coupling with a carboxylic acid containing an appropriately substituted Michael acceptor, and hydrolysis steps.

[0568] The final macrocyclic ester can be prepared by coupling amino-hexahydropyridazine-3-carboxylic acid methyl ester-boronate (2) with aryl-3-(5-bromo-1-ethyl-1H-indol-3-yl)-2,2-dimethylpropan-1-ol (1) in the presence of Pd catalyst, followed by hydrolysis and macrolactonization steps to obtain the appropriately protected macrocyclic intermediate (5). Deprotection and coupling with the appropriately substituted intermediate 4 yield the macrocyclic product. Additional deprotection and / or functionalization steps may be required to prepare the final compound.

[0569] Scheme 2. Alternative general synthesis of macrocyclic esters

[0570]

[0571] Alternatively, macrocyclic esters can be prepared as described in Scheme 2. An appropriately protected bromo-indolyl (6) is coupled with a boronate (3) in the presence of a Pd catalyst, followed by iodination, deprotection, and ester hydrolysis. Subsequent coupling with (S)-hexahydropyridazine-3-methyl carboxylate, followed by hydrolysis and macrolactonization, can produce the iodine intermediate (7). Coupling with an appropriately substituted boronate and alkylation in the presence of a Pd catalyst can yield the fully protected macrocycle (5). Additional deprotection or functionalization steps are required to prepare the final compound.

[0572] In addition, it will be appreciated by those skilled in the art that the compounds of the present disclosure can be synthesized using the methods described in the following examples, as well as synthetic methods known in the art of synthetic organic chemistry or variations thereof. These methods include, but are not limited to, the methods described in the following examples.

The compounds of Table 2 can be prepared using the methods disclosed herein, or using the methods disclosed herein in combination with the knowledge of those skilled in the art.

[0574] Scheme 3. General synthesis of macrocyclic esters

[0575]

[0576] An alternative general synthesis of macrocyclic esters is outlined in Scheme 3. Appropriately substituted indolylboronic acid esters (8) can be prepared starting from protected 3-(5-bromo-2-iodo-1H-indol-3-yl)-2,2-dimethylpropan-1-ol and an appropriately substituted boronic acid in a four-step process involving palladium-mediated coupling, alkylation, deprotection, and palladium-mediated borylation.

[0577] Methyl (S)-2-amino-3-(4-bromothiazol-2-yl)propanoyl)hexahydropyridazine-3-carboxylate (10) can be prepared by coupling (S)-2-amino-3-(4-bromothiazol-2-yl)propanoic acid (9) with methyl (S)-hexahydropyridazine-3-carboxylate.

[0578] The final macrocyclic ester can be prepared by coupling amino-3-(4-bromothiazol-2-yl)propionyl)hexahydropyridazine-3-carboxylic acid methyl ester (10) with an appropriately substituted indolyl boronate (8) in the presence of a Pd catalyst, followed by hydrolysis and macrolactonization steps to afford the appropriately protected macrocyclic intermediate (11). Deprotection and coupling with an appropriately substituted intermediate 4 can yield the macrocyclic product. Additional deprotection or functionalization steps may be required to prepare the final compound 13 or 14.

[0579] Scheme 4. General Synthesis of Macrocyclic Esters

[0580]

[0581] An alternative general synthesis of macrocyclic esters is outlined in Scheme 4. Appropriately substituted morpholine or alternative heterocyclic intermediates (15) can be coupled via palladium-mediated coupling with appropriately protected intermediates 1. Subsequent ester hydrolysis and coupling with piperazoic esters afford intermediates 16.

[0582] Macrocyclic esters can be prepared by hydrolysis, deprotection and macrocyclization steps. Subsequent deprotection and coupling with intermediate 4 (or analogs) yield the appropriately substituted final macrocyclic product. Additional deprotection or functionalization steps may be required to prepare the final compound 17.

[0583] Scheme 5. General Synthesis of Macrocyclic Esters

[0584]

[0585] An alternative general synthesis of macrocyclic esters is outlined in Scheme 5. Appropriately substituted macrocycles (20) can be prepared starting from appropriately protected boronate esters 18 and bromoindolyl intermediates (19) via palladium-mediated coupling, hydrolysis, coupling with piperazolyl esters, hydrolysis, deprotection, and macrocyclization steps. Subsequent coupling with appropriately substituted protected amino acids, followed by palladium-mediated coupling, affords intermediates 21. Additional deprotection and derivatization steps, including alkylation, may be required.

[0594] Unless expressly stated to the contrary, the compounds described herein, whether or not expressly stated, may be provided or utilized in the form of a salt, such as a pharmaceutically acceptable salt. As used herein, the term "pharmaceutically acceptable salt" refers to salts of the compounds described herein that are suitable for use in contact with human tissues without excessive toxicity, irritation, allergic reactions, etc., and that are commensurate with a reasonable benefit / risk ratio, within the scope of reasonable medical judgment. Pharmaceutically acceptable salts are well known in the art. For example, pharmaceutically acceptable salts are described in: Berge et al., J. Pharmaceutical Sciences 66: 1-19, 1977 and Pharmaceutical Salts: Properties, Selection, and Use, (P.H. Stahl and C.G. Wermuth eds.), Wiley-VCH, 2008. The salts may be prepared in situ during the final isolation and purification of the compounds described herein, or may be separated by reacting the free base group with a suitable organic acid.

[0595] The compounds of the present invention may have ionizable groups, so that they can be prepared into pharmaceutically acceptable salt forms. These salts may be acid addition salts involving inorganic or organic acids, or in the case where the compounds of the present invention are in acid form, the salts may be prepared from inorganic or organic bases. In some embodiments, the compound is prepared as a pharmaceutically acceptable salt form or used in a pharmaceutically acceptable salt form, which is prepared as an addition product of a pharmaceutically acceptable acid or base. Suitable pharmaceutically acceptable acids and bases are well known in the art, such as hydrochloric acid, sulfuric acid, hydrobromic acid, acetic acid, lactic acid, citric acid or tartaric acid, for forming acid addition salts; and potassium hydroxide, sodium hydroxide, ammonium hydroxide, caffeine, various amines, etc., for forming basic salts.

[0597] As used herein, the term "subject" refers to any member of the animal kingdom. In some embodiments, a "subject" refers to a human being at any stage of development. In some embodiments, a "subject" refers to a human patient. In some embodiments, a "subject" refers to a non-human animal. In some embodiments, the non-human animal is a mammal (e.g., a rodent, mouse, rat, rabbit, monkey, dog, cat, sheep, cattle, primate, or pig). In some embodiments, the subject includes, but is not limited to, mammals, birds, reptiles, amphibians, fish, or insects. In some embodiments, the subject may be a transgenic animal, a genetically engineered animal, or a clone.

[0598] As used herein, the term "dosage form" refers to a physical discrete unit of a compound (e.g., a compound of the present invention) for administration to a subject. Each unit contains a predetermined amount of compound. In some embodiments, this amount is the amount of a unit dose (or an integral portion thereof) suitable for administration according to a dosing regimen, which is determined to be associated with a desired or beneficial outcome when administered to a relevant population (i.e., according to a therapeutic dosing regimen). It will be understood by those skilled in the art that the total amount of the therapeutic composition or compound administered to a particular subject is determined by one or more attending physicians and may involve the administration of a variety of dosage forms.

[0599] As used herein, the term "dosage regimen" refers to a group of unit doses (usually more than one unit dose) administered individually to a subject, the unit doses typically being spaced apart for a certain period of time. In some embodiments, a given therapeutic compound (e.g., a compound of the present invention) has a recommended dosing regimen that may involve one or more doses. In some embodiments, the dosing regimen comprises multiple doses, each of which is spaced apart by a time period of the same length; in some embodiments, the dosing regimen comprises multiple doses and at least two different time periods for separating individual doses. In some embodiments, all doses within the dosing regimen are the same unit dose amount. In some embodiments, the different doses within the dosing regimen are different amounts. In some embodiments, the dosing regimen comprises a first dose of the amount of a first dose, followed by one or more additional doses of the amount of a second dose different from the amount of the first dose. In some embodiments, the dosing regimen comprises a first dose of the amount of a first dose, followed by one or more additional doses of the amount of a second dose identical to the amount of the first dose. In some embodiments, the dosing regimen is associated with desired or beneficial results when applied to a relevant population (i.e., a therapeutic dosing regimen).

[0600] A "therapeutic regimen" refers to a regimen of dosages whose administration is associated with desired or beneficial therapeutic results in the relevant population.

[0601] The term "treatment" ("treatment / treat / treating") in its broadest sense refers to any administration of a substance (e.g., a compound of the present invention) that partially or completely alleviates, ameliorates, alleviates, inhibits one or more symptoms, features, or causes of a particular disease, disorder, or condition; delays its onset; reduces its severity; or reduces its occurrence. In some embodiments, this treatment may be applied to a subject who does not show signs of the relevant disease, disorder, or condition or a subject who only shows early signs of the disease, disorder, or condition. Alternatively or additionally, in some embodiments, treatment may be applied to a subject who shows one or more established signs of the relevant disease, disorder, or condition. In some embodiments, treatment may be used for a subject diagnosed with a relevant disease, disorder, or condition. In some embodiments, treatment may be used for a subject known to have one or more susceptibility factors that are statistically associated with an increased risk of developing a relevant disease, disorder, or condition.

[0602] The term "therapeutically effective amount" means an amount sufficient to treat a disease, disorder or condition when administered to a population suffering from or susceptible to the disease, disorder or condition according to a therapeutic dosing regimen. In some embodiments, a therapeutically effective amount is an amount that reduces the incidence or severity of one or more symptoms of the disease, disorder or condition or delays its onset. It will be understood by those skilled in the art that the term "therapeutically effective amount" does not actually require the desired successful treatment to be achieved in a particular individual. In fact, a therapeutically effective amount may be an amount that provides a specific desired pharmacological response in a considerable number of subjects when administered to a patient in need of such treatment. It is particularly important to understand that a particular subject may actually be "refractory" to the "therapeutically effective amount." In some embodiments, the therapeutically effective amount mentioned may refer to an amount as measured in one or more specific tissues (e.g., tissues affected by the disease, disorder or condition) or fluids (e.g., blood, saliva, serum, sweat, tears, urine). It will be understood by those skilled in the art that in some embodiments, a therapeutically effective amount may be formulated as a single dose or administered in a single dose. In some embodiments, a therapeutically effective amount can be formulated as multiple doses, for example, formulated as part of a dosing regimen, or administered as multiple doses.

[0603] For use as a treatment for a subject, the compound of the present invention or a pharmaceutically acceptable salt thereof can be formulated as a pharmaceutical composition or a veterinary composition. Depending on the subject to be treated, the mode of administration, and the desired type of treatment, such as prevention, control, or treatment, the compound or a pharmaceutically acceptable salt thereof is formulated in a manner consistent with these parameters. An overview of such techniques can be found in Remington: The Science and Practice of Pharmacy, 21st ed., Lippincott Williams & Wilkins, (2005); and Encyclopedia of Pharmaceutical Technology, edited by J. Swarbrick and J. C. Boylan, 1988-1999, Marcel Dekker, New York, each of which is incorporated herein by reference.

[0604] The compositions can be prepared according to conventional mixing, granulation or coating methods, respectively, and the pharmaceutical compositions of the present invention may contain about 0.1% to about 99%, about 5% to about 90%, or about 1% to about 20% of the compound of the present invention or a pharmaceutically acceptable salt thereof by weight or volume. In some embodiments, the compound described herein or a pharmaceutically acceptable salt thereof may be present in an amount of 1-95% by weight of the total amount of the composition, such as a pharmaceutical composition.

[0605] The composition can be provided in the dosage form suitable for following application: intra-articular, oral, parenteral (such as intravenous, intramuscular), rectum, skin, subcutaneous, surface, transdermal, sublingual, nasal, vaginal, intracapsular, intraurethral, ​​intrathecal, epidural, ear or eye application, or by injection, suction or direct contact with nose, urogenital, genitalia or oral mucosa. Therefore, the pharmaceutical composition can be in the form of, for example, tablets, capsules, pills, powders, granules, suspensions, emulsions, solutions, gels (including hydrogels), pastes, ointments, creams, plasters, medicinal liquids, osmotic delivery devices, suppositories, enemas, injections, implants, sprays, preparations suitable for iontophoresis delivery or aerosols. The composition can be prepared according to conventional medical practice.

[0606] As used herein, the term "administering" refers to administering a composition (e.g., a compound or a formulation comprising a compound as described herein) to a subject or system. Administration to an animal subject (e.g., to a human) can be performed by any appropriate route. For example, in some embodiments, administration can be intrabronchial (including by bronchial instillation), buccal, enteral, intradermal, intraarterial, intradermal, intragastric, intramedullary, intramuscular, intranasal, intraperitoneal, intrathecal, intravenous, intracapsular, transmucosal, nasal, oral, rectal, subcutaneous, sublingual, topical, tracheal (including by intratracheal instillation), transdermal, vaginal, or vitreous administration.

[0607] The preparation can be prepared in a manner suitable for systemic administration or surface or topical administration. Systemic preparations include preparations designed for injection (e.g., intramuscular, intravenous or subcutaneous injection) or can be prepared for transdermal, transmucosal or oral administration. The preparation will typically include a diluent, and in some cases, adjuvants, buffers, preservatives, etc. The compound or its pharmaceutically acceptable salt can also be administered in liposome compositions or in microemulsion form.

[0608] For injection, the formulation can be prepared in conventional forms, such as liquid solutions or suspensions, or solid forms suitable for preparation as solutions or suspensions in liquids prior to injection, or in the form of emulsions. Suitable excipients include, for example, water, physiological saline, dextrose, glycerol, and the like. Such compositions may also contain a certain amount of non-toxic auxiliary substances, such as wetting agents or emulsifiers, pH buffers, and the like, for example, sodium acetate, sorbitan monolaurate, and the like.

[0609] Various sustained-release drug systems have also been designed. See, for example, U.S. Patent No. 5,624,677.

[0610] Systemic administration can also include relatively non-invasive methods, such as using suppositories, transdermal patches, transmucosal delivery, and intranasal administration. Oral administration is also suitable for the compounds of the present invention or pharmaceutically acceptable salts thereof. It will be appreciated in the art that suitable forms include syrups, capsules, and tablets.

[0611] Each compound as described herein or its pharmaceutically acceptable salt can be formulated in a variety of ways known in the art. For example, the first agent and the second agent in the combination therapy can be formulated together or separately. Other modalities of combination therapy are also described herein.

[0612] Individual or separately formulated medicaments can be packaged together in a kit form. Non-limiting examples include, but are not limited to, kits containing, for example, two pills, one pill and powder, a suppository or a liquid in a vial, two topical creams, etc. The kit may include optional components that help to administer a unit dose to a subject, such as vials, syringes for injection, custom IV delivery systems, inhalers, etc., to reconstitute the powder form. In addition, the unit dose kit may contain instructions for the preparation and administration of the composition. The kit may be manufactured as a disposable unit dose for a subject, for multiple uses for a specific subject (at a constant dose, or wherein the efficacy of an individual compound or its pharmaceutically acceptable salt may vary with treatment progress); or the kit may contain multiple doses suitable for administration to multiple subjects ("whole package"). The kit components may be assembled in cartons, blister packs, bottles, tubes, etc.

[0613] Formulations for oral use include tablets containing the active ingredient in admixture with non-toxic pharmaceutically acceptable excipients. These excipients may be, for example, inert diluents or fillers (e.g., sucrose, sorbitol, sugar, mannitol, microcrystalline cellulose, starches including potato starch, calcium carbonate, sodium chloride, lactose, calcium phosphate, calcium sulfate, or sodium phosphate); granulating and disintegrants (e.g., cellulose derivatives including microcrystalline cellulose, starches including potato starch, cross-linked sodium carboxymethylcellulose, alginates, or alginic acid); binders (e.g., sucrose, glucose, sorbitol, gum arabic, alginic acid, sodium alginate, gelatin, starch, pregelatinized starch, microcrystalline cellulose, magnesium aluminum silicate, sodium carboxymethylcellulose, methylcellulose, optionally substituted hydroxypropyl methylcellulose, ethylcellulose, polyvinyl pyrrolidone, or polyethylene glycol); and lubricants, glidants, and anti-adherents (e.g., magnesium stearate, zinc stearate, stearic acid, silicon dioxide, hydrogenated vegetable oil, or talc). Other pharmaceutically acceptable excipients may be colorants, flavorings, plasticizers, humectants, buffers, and the like.

[0614] Two or more compounds can be mixed together in a tablet, capsule or other vehicle, or can be separated. In one example, a first compound is contained on the inside of a tablet, and a second compound is on the outside, so that the majority of the second compound is released before the first compound is released.

[0615] Formulations for oral use may also be provided in the form of chewable tablets, or in the form of hard gelatin capsules in which the active ingredient is mixed with an inert solid diluent (e.g., potato starch, lactose, microcrystalline cellulose, calcium carbonate, calcium phosphate, or kaolin); or in the form of soft gelatin capsules in which the active ingredient is mixed with water or an oil medium, such as peanut oil, liquid paraffin, or olive oil. Powders, granules, and granules may be prepared using the ingredients mentioned above for tablets and capsules in a conventional manner, using, for example, a mixer, a fluidized bed apparatus, or a spray drying apparatus.

[0616] Dissolution or diffusion controlled release can be achieved by appropriately coating tablets, capsules, granules or granular preparations of the compound, or by incorporating the compound or its pharmaceutically acceptable salt into a suitable matrix. The controlled release coating can include one or more of the above-mentioned coating materials, such as shellac, beeswax, glycowax, castor wax, carnauba wax, stearyl alcohol, glyceryl monostearate, glyceryl distearate, glyceryl palmitostearate, ethyl cellulose, acrylic resins, dl-polylactic acid, cellulose acetate butyrate, polyvinyl chloride, polyvinyl acetate, vinyl pyrrolidone, polyethylene, polymethacrylate, methyl methacrylate, 2-optionally substituted hydroxymethylacrylate, methacrylate hydrogel, 1,3 butylene glycol, ethylene glycol methacrylate or polyethylene glycol. In controlled release matrix formulations, the matrix material may also include, for example, hydrated methylcellulose, carnauba wax and stearyl alcohol, carbopol 934, silicone, tristearin, methyl acrylate-methyl methacrylate, polyvinyl chloride, polyethylene, or halogenated fluorocarbons.

[0617] Liquid forms for oral administration that may incorporate the compounds of the invention, or pharmaceutically acceptable salts thereof, and compositions include aqueous solutions, suitably flavored syrups, aqueous or oily suspensions, and emulsions flavored with edible oils such as cottonseed oil, sesame oil, coconut oil, or peanut oil, as well as elixirs and similar pharmaceutical vehicles.

[0618] In general, when administered to humans, the oral dosage of any compound of the present invention or a pharmaceutically acceptable salt thereof will depend on the properties of the compound and can be readily determined by one skilled in the art. The dosage can be, for example, from about 0.001 mg to about 2000 mg per day, from about 1 mg to about 1000 mg per day, from about 5 mg to about 500 mg per day, from about 100 mg to about 1500 mg per day, from about 500 mg to about 1500 mg per day, from about 500 mg to about 2000 mg per day, or any range derived therefrom.

[0619] In some embodiments, the pharmaceutical composition may also include an additional compound with antiproliferative activity. Depending on the mode of administration, the compound or its pharmaceutically acceptable salt will be formulated into a suitable composition for delivery. Each compound or its pharmaceutically acceptable salt in the combination therapy can be formulated in a variety of ways known in the art. For example, the first agent and the second agent in the combination therapy can be formulated together or separately. Ideally, the first agent and the second agent are formulated together so that the agents are administered simultaneously or nearly simultaneously.

[0620] It will be understood that the compounds and pharmaceutical compositions of the present invention can be formulated and used in combination therapies, that is, they can be formulated with or administered concurrently with, before, or after the administration of one or more other desired therapeutic agents or medical procedures. The specific combination of therapies (therapeutics or procedures) used in a combination regimen should take into account the compatibility of the desired therapeutic agents or procedures with the desired therapeutic effect to be achieved. It will also be understood that the therapies employed may achieve the desired effect for the same condition, or they may achieve different effects (e.g., control any adverse effects).

[0621] As described herein, administration of each drug in the combination therapy can independently be from once to four times daily for a period of one day to one year, and may even be continued for the lifetime of the subject. Chronic, long-term administration may be required.

[0690] MCL-1 inhibitors are known in the art and include, but are not limited to, AMG-176, MIK665, and S63845. The myeloid cell leukemia-1 (MCL-1) protein is one of the key anti-apoptotic members of the B-cell lymphoma-2 (BCL-2) protein family. Overexpression of MCL-1 is closely associated with tumor progression and resistance to not only traditional chemotherapy but also targeted therapeutics including BCL-2 inhibitors such as ABT-263.

[0691] In some embodiments, the additional therapeutic agent is a SHP2 inhibitor. SHP2 is known in the art. SHP2 is a non-receptor protein tyrosine phosphatase encoded by the PTPN11 gene that contributes to a variety of cellular functions, including proliferation, differentiation, cell cycle maintenance, and migration. SHP2 has two N-terminal Src homology 2 domains (N-SH2 and C-SH2), a catalytic domain (PTP), and a C-terminal tail. The two SH2 domains control the subcellular localization and functional regulation of SHP2. The molecule exists in an inactive, autoinhibitory conformation stabilized by a binding network involving residues from the N-SH2 and PTP domains. Stimulation with, for example, cytokines or growth factors that act through receptor tyrosine kinases (RTKs) results in exposure of the catalytic site, leading to enzymatic activation of SHP2.

[0692] SHP2 is involved in signaling via the RAS-mitogen-activated protein kinase (MAPK), i.e., JAK-STAT or phosphoinositide 3-kinase-AKT pathway. Mutations in the PTPN11 gene and subsequently in SHP2 have been identified in several human developmental diseases, such as Noonan Syndrome and Leopard Syndrome, as well as in human cancers such as juvenile myelomonocytic leukemia, neuroblastoma, melanoma, acute myeloid leukemia, and breast, lung, and colon cancers. Some of these mutations destabilize the autoinhibitory conformation of SHP2 and promote its autoactivation or enhanced growth factor-driven activation. Therefore, SHP2 represents a particularly interesting target for the development of novel therapies for various diseases, including cancer. The combination of SHP2 inhibitors (e.g., RMC-4550 or SHP099) with RAS pathway inhibitors (e.g., MEK inhibitors) has been shown to inhibit the proliferation of multiple cancer cell lines (e.g., pancreatic, lung, ovarian, and breast cancer) in vitro. Therefore, combination therapy involving SHP2 inhibitors and RAS pathway inhibitors may be a general strategy for preventing tumor resistance in various malignancies.
