AI Technical Summary
The prior art is difficult to effectively target and inhibit the activated forms of Ras protein, resulting in difficulty in developing anticancer drugs, especially for Ras mutation-driven cancers.
By synthesizing ligands form a high-affinity three-component complex with Ras protein and cytoplasmic chaperone cyclophilin A, a new binding pocket is induced, affecting the interaction sites between Ras and downstream effector molecules, and thus inhibiting Ras activation.
Selective inhibition of Ras protein is achieved, potentially treating Ras mutation-driven cancers, providing new anti-cancer therapy options.

Abstract
Description
[0001] This application is a divisional application of the invention patent application with application date of June 9, 2023, application number 2023800582279, and invention name “Macrocyclic RAS Inhibitors”.
[0002] CROSS-REFERENCE TO RELATED APPLICATIONS
[0003] This application claims the benefit of priority to U.S. Application No. 63 / 351,146, filed on June 10, 2022, and U.S. Application No. 63 / 455,649, filed on March 30, 2023, each of which is hereby incorporated by reference in its entirety. Background Art
[0004] The vast majority of small molecule drugs work by binding to functionally important pockets on the target protein, 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 binding to its substrate. The fact that many such drug / target interaction pairs are known may have misled some people into believing that, given reasonable time, effort, and resources, small molecule modulators for most (if not all) proteins can be found. This is far from the case. According to current estimates, 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 refractory or intractable to the discovery of small molecule drugs. Such targets are often referred to as "undruggable". These undruggable targets include a large number of human proteins of important medical significance that have not yet been developed. Therefore, there is great interest in discovering new molecular patterns that can regulate the functions of such undruggable targets.
[0005] It has been confirmed in the literature that Ras proteins (K-Ras, H-Ras and N-Ras) play an important role in various human cancers and are therefore suitable targets for anticancer therapy. In fact, mutations in Ras proteins account for approximately 30% of all human cancers in the United States, many of which are fatal. Ras proteins are commonly dysregulated in human tumors through activating mutations, overexpression or upstream activation, and activating mutations of Ras are often found in human cancers. For example, activating mutations at codon 12 in Ras proteins function by inhibiting both the GTPase activating protein (GAP) dependency and the intrinsic hydrolysis rate of GTP, significantly biasing the population of Ras mutant proteins towards the "on" (GTP-bound) state (Ras (on)), thereby causing oncogenic MAPK signaling. Notably, Ras exhibits a picomolar affinity for GTP, allowing Ras to be activated even in the presence of low concentrations of this nucleotide. Ras mutations at codons 13 (eg, G13D) and 61 (eg, Q61K) also cause oncogenic activity in some cancers.
[0006] Despite extensive drug discovery efforts targeting Ras over the past few decades, drugs that directly target the "on" form of Ras have yet to be approved. Further efforts are needed to discover additional drugs for cancers driven by various Ras mutations. Summary of the Invention
[0007] Provided herein are Ras inhibitors. These Ras inhibitors target, i.e., selectively bind to or inhibit Ras (turn on) (e.g., selectively bind to the inactive state of GDP compared to Ras). 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 (presenting protein) (e.g., cyclophilin A) that is widely expressed in cells. More specifically, in some embodiments, the Ras inhibitors described herein induce a new binding pocket in Ras by driving the formation of a high-affinity three-complex between the Ras protein and the widely expressed cytoplasmic chaperone cyclophilin A (CYPA). Without being bound by theory, the inventors believe that one way in which the inhibitory effect of Ras is affected by the compounds of the present invention and the complexes they form is through the spatial closure of the interaction site between Ras and downstream effector molecules (such as RAF and PI3K), which are required for the propagation of oncogenic signals.

[0103] Definitions and Chemical Terms
[0104] In this application, unless the context indicates otherwise, (i) the term "a / a" means "one or more"; (ii) the term "or" is used to mean "and / or" (unless explicitly indicated to refer to only alternatives or the alternatives are mutually exclusive), although this disclosure supports definitions referring only to alternatives and "and / or"; (iii) the terms "comprising" and "including" are understood to cover the listed components or steps alone or together with one or more other components or steps; and (iv) where a range is provided, the endpoints are included.
[0105] As used herein, the term "about" is used to indicate that a value includes the standard deviation of the error of the device or method for determining the value. In certain embodiments, the term "about" refers to a range of values within a range of (greater than or less than) 25%, 20%, 19%, 18%, 17%, 16%, 15%, 14%, 13%, 12%, 11%, 10%, 9%, 8%, 7%, 6%, 5%, 4%, 3%, 2%, 1% or less in either direction of the stated value, unless otherwise stated or otherwise apparent from the context (e.g., wherein such numerals will exceed 100% of possible values).
[0106] As used herein, the term "adjacent," in the context of describing adjacent atoms, refers to divalent atoms that are directly connected by a covalent bond.
[0107] As used herein, “compounds of the invention” and similar terms, whether explicitly mentioned or not, refer to the Ras inhibitors described herein, including compounds of Formula Ia or Formula Ib and subformulas thereof and compounds of Table 1, as well as salts (e.g., pharmaceutically acceptable salts), solvates, hydrates, stereoisomers (including atropisomers), and tautomers thereof.
[0108] The term "wild-type" refers to an entity having structure or activity as found in nature in a "normal" (as opposed to mutant, diseased, altered, etc.) state or background. Those skilled in the art will appreciate that wild-type genes and polypeptides often exist in multiple different forms (e.g., alleles).
[0109] Those skilled in the art will appreciate that certain compounds described herein may exist in one or more different isomers (e.g., stereoisomers, geometric isomers, atropisomers, tautomers) or isotopic forms (e.g., wherein one or more atoms have been substituted with a different isotope of an atom, such as hydrogen for deuterium). Unless otherwise indicated or clear from the context, the structures shown are understood to represent any such isomers or isotopic forms, either individually or in combination.
[0110] The compounds described herein may be asymmetric (e.g., having one or more stereocenters). Unless otherwise indicated, all stereoisomers, such as enantiomers and diastereomers, are intended. Compounds of the present disclosure containing asymmetrically substituted carbon atoms can be separated in optically active or racemic forms. Methods for preparing optically active forms from optically active starting materials are known in the art, such as by resolving racemic mixtures or by stereoselective synthesis. Many geometric isomers of alkenes, C=N double bonds, etc. may also be present in the compounds described herein, and all such stable isomers are encompassed in the present disclosure. Cis and trans geometric isomers of the compounds of the present disclosure are described and can be separated as mixtures of isomers or as separated isomeric forms.
[0111] In some embodiments, one or more compounds presented herein can exist in different tautomeric forms. As will be clear from the context, reference to such compounds encompasses all such tautomeric forms unless expressly excluded. In some embodiments, tautomeric forms result from the exchange of a single bond with an adjacent double bond and the concomitant migration of a proton. In certain embodiments, tautomeric forms may be prototropic tautomers, which are isomeric protonation states having the same empirical formula and total charge as the reference form. Examples of moieties with prototropic tautomeric forms are keto-enol pairs, amide-imidic acid pairs, lactam-lactim pairs, amide-imidic acid pairs, enamine-imine pairs, and cyclic forms in which a proton can occupy two or more positions in a heterocyclic ring system, such as 1H-imidazole and 3H-imidazole, 1H-1,2,4-triazole, 2H-1,2,4-triazole and 4H-1,2,4-triazole, 1H-isoindole and 2H-isoindole, and 1H-pyrazole and 2H-pyrazole. In some embodiments, the tautomeric forms may be in equilibrium or sterically locked into one form by appropriate substitution. In certain embodiments, the tautomeric forms are caused by acetal interconversion.
[0112] Unless otherwise stated, structures shown herein are also meant to include compounds that differ only in the presence of one or more isotopically enriched atoms. Exemplary isotopes that can be incorporated into the compounds of the present invention include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorus, sulfur, fluorine, chlorine, and iodine, such as 2H. 3 H. 11 C. 13 C. 14 C. 13 N. 15 N. 15 O. 17 O. 18 O. 32 P. 33 P. 35 S. 18 F. 36 Cl, 123 I and 125 I. Isotope-labeled compounds (e.g., 3 H and 14 C-labeled ones) can be used in compound or substrate tissue distribution assays. 3 H) and carbon-14 (i.e., 14 C) isotopes can be useful due to their ease of preparation and detectability. In addition, heavier isotopes such as deuterium (i.e., 2 H) substitution may provide certain therapeutic advantages due to greater metabolic stability (e.g., increased in vivo half-life or reduced dosage requirements). In some embodiments, one or more hydrogen atoms are replaced by 2 H or 3 H replacement, or one or more carbon atoms are 13 C or 14 C-enriched carbon replacement. Positron-emitting isotopes (such as 15 O. 13 N. 11 C and 18 F) can be used in positron emission tomography (PET) studies to examine substrate receptor occupancy. The preparation of isotopically labeled compounds is known to those skilled in the art. For example, isotopically labeled compounds can generally be prepared by following procedures analogous to those disclosed for the compounds of the invention described herein, by substituting an isotopically labeled reagent for a non-isotopically labeled reagent.
[0113] As is known in the art, many chemical entities can adopt a variety of different solid forms, such as amorphous forms or crystalline forms (e.g., polymorphs, hydrates, solvates). In some embodiments, the compounds of the present invention can be used in any such form, including in any solid form. In some embodiments, the compounds described or illustrated herein can be provided or used in the form of a hydrate or solvate.
[0114] At various positions in this specification, substituents of compounds of the present disclosure are disclosed as groups or in ranges. The disclosure is specifically intended to include every individual subcombination of members of such groups and ranges. For example, the term "C1-C6 alkyl" is specifically intended to disclose methyl, ethyl, C3 alkyl, C4 alkyl, C5 alkyl, and C6 alkyl individually. Furthermore, where a compound includes multiple positions where substituents are disclosed as groups or in ranges, unless otherwise indicated, the disclosure is intended to cover individual compounds and groups of compounds (e.g., classes and subclasses) containing every individual subcombination of members at each position.
[0115] The term "optionally substituted X" (e.g., "optionally substituted alkyl") is intended to be equivalent to "X, wherein X is optionally substituted" (e.g., "alkyl, wherein the alkyl is optionally substituted"). The feature "X" (e.g., alkyl) itself is not intended to mean that it is optional. As described herein, certain compounds of interest may contain one or more "optionally substituted" moieties. In general, the term "substituted," whether preceded by the term "optionally" or not, means that one or more hydrogens of the designated moiety are replaced with a suitable substituent, such as any of the substituents or groups described herein. Unless otherwise indicated, an "optionally substituted" group may have a suitable substituent at each substitutable position of the group, and when more than one position in any given structure may be substituted with more than one substituent selected from a specified group, the substituents at each position may be the same or different.

DETAILED DESCRIPTION
[0159] Compound
[0160] Provided herein are Ras inhibitors. These Ras inhibitors target, i.e., selectively bind to or inhibit Ras (on) (e.g., selectively bind to or inhibit the GDP-bound inactive state of Ras). As used herein, the term "RAS (on) inhibitor" refers to an inhibitor that targets (i.e., selectively binds to or inhibits) the GTP-bound active state of RAS (e.g., selectively binds to or inhibits the GDP-bound inactive state of RAS). The inhibition of the GTP-bound active state of RAS includes, for example, inhibition of oncogenic signaling from the GTP-bound active state of RAS. In some embodiments, a RAS (on) inhibitor is an inhibitor that selectively binds to and inhibits the GTP-bound active state of RAS. In certain embodiments, a RAS (on) inhibitor may also bind to or inhibit the GDP-bound inactive state of RAS (e.g., with a lower affinity or inhibition constant compared to the GTP-bound active state of RAS). In some embodiments, a RAS (on) inhibitor has a molecular weight between 800 and 1100 Da (including endpoints). Thus, for example, the term "KRAS (on) inhibitor" refers to any inhibitor that binds to KRAS in its GTP-bound "on" position. G12C A "(on) inhibitor" is a KRAS inhibitor that selectively binds to or targets the G12C mutant form of KRAS. Non-limiting examples of RAS (on) inhibitors are provided in WO 2021091982, WO 2021091967, WO 2021091956 and WO2020132597, some of which are KRAS G12C (Turn on) inhibitor.
[0161] As used herein, the term "RAS (off) inhibitor" refers to an inhibitor that targets (i.e., selectively binds to or inhibits) the GDP-bound inactive state of RAS (e.g., is selective over the GTP-bound active state of RAS). Inhibition of the GDP-bound inactive state of RAS includes, for example, sequestering the inactive state by inhibiting the exchange of GDP for GTP, thereby inhibiting RAS from adopting an active conformation. In certain embodiments, a RAS (off) inhibitor may also bind to or inhibit the GTP-bound active state of RAS (e.g., with a lower affinity or inhibition constant than the GDP-bound inactive state of RAS). In some embodiments, a RAS (off) inhibitor has a molecular weight of less than 700 Da. In some embodiments, a RAS (off) inhibitor has a molecular weight of less than 700 Da. Thus, for example, the term "KRAS (off) inhibitor" refers to any inhibitor that binds to KRAS in its GDP-bound "off" position. "KRAS G12C A "(off) inhibitor" is a KRAS inhibitor that selectively binds to or targets the G12C mutant form of KRAS. G12C KRAS (off) inhibitors are known in the art, and non-limiting examples include adagrasib and sotorasib. Additional KRAS (off) inhibitors are provided herein.
[0162] The term "inhibitor" means a compound or agent (eg, peptide, antibody) that prevents a biomolecule (eg, protein) from completing or initiating a reaction. An inhibitor can inhibit a reaction by competitive, non-competitive, or non-competitive means.
[0163] 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 (presenting protein) (e.g., cyclophilin A) that is widely expressed in cells. More specifically, in some embodiments, the Ras inhibitors described herein induce a new binding pocket in Ras by driving the formation of a high-affinity three-complex between the Ras protein and the widely expressed cytoplasmic chaperone cyclophilin A (CYPA). Without being bound by theory, the inventors believe that one way in which the inhibition of Ras is affected by the compounds of the invention and the complexes they form is through steric closure of the interaction site between Ras and downstream effector molecules (such as RAF), which are required for propagation of oncogenic signals.
[0164] Without being bound by theory, the inventors speculate that non-covalent interactions of the compounds of the present invention with Ras and chaperone proteins (e.g., cyclophilin A) may contribute to the inhibition of Ras activity. For example, van der Waals interactions, hydrophobic interactions, hydrophilic interactions, and hydrogen bonding interactions, as well as combinations thereof, may contribute to the ability of the compounds of the present invention to form complexes and act as Ras inhibitors. Thus, the compounds of the present invention may inhibit a variety of Ras proteins (e.g., wild-type Ras or Ras amp , or K-Ras, N-Ras, H-Ras, and mutants thereof at positions 12, 13, and 61, such as G12C, G12D, G12V, G12S, G13C, G13D, and Q61L, as well as other mutants described herein, and combinations of Ras proteins).
[0165] Thus, provided herein are compounds having the structure of Formula Ia or pharmaceutically acceptable salts thereof:

[0373] The compounds described herein can be prepared from commercially available starting materials or synthesized using known organic, inorganic, or enzymatic methods.
[0374] The compounds of the present invention can be prepared by methods known to those skilled in the art, such as those disclosed in WO 2021 / 091956 and WO2022 / 060836 in combination with known synthetic organic chemistry techniques, and the respective disclosures of the patents are incorporated herein by reference. For example, the compounds of the present invention can be synthesized using the methods described in the schemes below, together with synthetic methods known in the field of synthetic organic chemistry, or variations thereof as understood by those skilled in the art. These methods include, but are not limited to, those described in the schemes below.
[0375] Scheme 1. General Synthesis of Macrocyclic Ester
[0376]
[0377] The general synthesis of macrocyclic esters is outlined in Scheme 1. Appropriately substituted indolylboronic acid esters (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 four steps involving palladium-mediated coupling, alkylation, deprotection, and palladium-mediated borylation.
[0378] Methyl-amino-3-(4-bromothiazol-2-yl)propanoyl)hexahydropyridazine-3-carboxylate (3) can be prepared by coupling (S)-2-amino-3-(4-bromothiazol-2-yl)propanoic acid (2) with (S)-hexahydropyridazine-3-carboxylic acid methyl ester.
[0379] The final macrocyclic ester can be prepared by coupling methyl-amino-3-(4-bromothiazol-2-yl)propionyl)hexahydropyridazine-3-carboxylate (3) with an appropriately substituted indolyl boronate (1) in the presence of a Pd catalyst, followed by hydrolysis and macrolactonization steps to afford the appropriately protected macrocyclic intermediate (5). Deprotection and coupling with an appropriately substituted carboxylic acid (or other coupling partner) can yield the macrocyclic product. Additional deprotection or functionalization steps may be required to yield the final compound 6.
[0380] Furthermore, with reference to Scheme 1, the thiazole may be replaced by an alternative optionally substituted 5- to 6-membered heteroarylene or an optionally substituted 3- to 6-membered cycloalkylene, an optionally substituted 3- to 6-membered heterocycloalkylene (e.g., morpholino), or an optionally substituted 6-membered arylene (e.g., phenyl).
[0381] Scheme 2. Alternative general synthesis of macrocyclic esters
[0382]
[0383] Alternatively, macrocyclic esters can be prepared as described in Scheme 2. Appropriately substituted and protected indolyl boronates (7) can be coupled with (S)-2-amino-3-(4-bromothiazol-2-yl)propionic acid 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 yield the iodinated intermediate (11). Subsequent palladium-mediated borylation and coupling with an appropriately substituted iodoaryl or iodoheteroaryl intermediate in the presence of a Pd catalyst can produce the appropriately protected macrocyclic intermediate. Alkylation, deprotection, and coupling with an appropriately substituted carboxylic acid (or other coupling partner) produce the macrocyclic product. Additional deprotection or functionalization steps may be required to produce the final compound 6.
[0384] Furthermore, with reference to Scheme 2, the thiazole may be replaced by an alternative optionally substituted 5- to 6-membered heteroarylene or an optionally substituted 3- to 6-membered cycloalkylene, an optionally substituted 3- to 6-membered heterocycloalkylene (e.g., morpholino), or an optionally substituted 6-membered arylene (e.g., phenyl).
[0385] The compounds of Table 1 herein were prepared using the methods disclosed herein or using the methods described herein in combination with the knowledge of one skilled in the art.

[0392] Unless expressly stated to the contrary, whether or not expressly stated, the compounds described herein can be provided or used in salt form (e.g., pharmaceutically acceptable salt form). As used herein, the term "pharmaceutically acceptable salt" refers to salts of compounds described herein that are suitable for use in contact with the tissues of humans and other animals without excessive toxicity, irritation, allergic reactions, etc., and that conform to a reasonable benefit / risk ratio, within the scope of reasonable medical judgment. Pharmaceutically acceptable salts are well known in the art. For example, 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 describe pharmaceutically acceptable salts. Salts can be prepared in situ during the final separation and purification of the compounds described herein or prepared separately by reacting the free base group with a suitable organic acid.
[0393] The compounds of the present invention may have an ionizable group so that they can be prepared as pharmaceutically acceptable salts. These salts may be acid addition salts relating to inorganic or organic acids, or in the case of an acidic form of the compounds of the present invention, the salts may be prepared by inorganic or organic bases. In some embodiments, the compound is prepared into a pharmaceutically acceptable salt or is used in the form of a pharmaceutically acceptable salt, which is prepared into an addition product of a pharmaceutically acceptable acid or base.

[0395] As used herein, the term "subject" refers to any member of the animal kingdom. In some embodiments, a "subject" refers to a person 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 worms. In some embodiments, the subject can be a transgenic animal, a genetically engineered animal, or a clone.
[0396] 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, such an amount is a unit dose amount (or its entire portion) suitable for administration according to a dosage regimen that has been determined to be relevant to the desired or beneficial results when administered to a relevant group (i.e., using a therapeutic dosage regimen). It is 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 multiple dosage forms. As used herein, the term "dosage regimen" refers to a group of unit doses (usually more than one) that are typically administered separately to a subject in separate time periods. In some embodiments, a given therapeutic compound (e.g., a compound of the present invention) has a recommended dosage regimen that may involve one or more doses. In some embodiments, the dosage regimen includes multiple doses, each of which is separated by a time period of the same length; in some embodiments, the dosage regimen includes multiple doses and at least two different time periods separating individual doses. In some embodiments, all doses within the dosage regimen have the same unit dose amount. In some embodiments, different doses within the dosage regimen have different amounts. In some embodiments, a dosing regimen comprises a first dose of a first dose amount, followed by one or more additional doses of a second dose amount different from the first dose amount. In some embodiments, a dosing regimen comprises a first dose of a first dose amount, followed by one or more additional doses of a second dose amount that is the same as the first dose amount. In some embodiments, a dosing regimen is associated with a desired or beneficial outcome when administered in a relevant population (i.e., is a therapeutic dosing regimen).
[0397] A "therapeutic regimen" refers to a regimen of dosages whose administration in the relevant population is associated with desired or beneficial therapeutic outcomes.
[0398] The term "treatment" (as well as "treat" or "treating") broadly refers to any administration of a substance (e.g., a compound of the present invention) that partially or completely alleviates, ameliorates, alleviates, suppresses, delays the onset of, reduces the severity of, or reduces the incidence of one or more symptoms, features, or causes of a particular disease, disorder, or condition. In some embodiments, such treatment may be administered to a subject who does not show signs of the relevant disease, disorder, or condition, or to a subject who shows only early signs of the disease, disorder, or condition. Alternatively or additionally, in some embodiments, treatment may be administered to a subject who shows one or more established signs of the relevant disease, disorder, or condition. In some embodiments, treatment may be treatment of a subject who has been diagnosed with the relevant disease, disorder, or condition. In some embodiments, treatment may be treatment of a subject who is known to have one or more susceptibility factors that are statistically associated with an increased risk of developing the relevant disease, disorder, or condition.
[0399] The term "therapeutically effective amount" means an amount sufficient to treat the disease, disorder or illness when administered to a population suffering from or susceptible to the disease, disorder or illness 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 illness or delays its onset. Those of ordinary skill in the art will understand that the term "therapeutically effective amount" does not actually require successful treatment in a particular individual. On the contrary, a therapeutically effective amount can be an amount that provides a specific desired pharmacological response in a large number of subjects when administered to a patient in need of such treatment. In particular, it should be understood that a particular subject may actually be "refractory" to a "therapeutically effective amount". In some embodiments, reference to a therapeutically effective amount may refer to an amount measured in one or more specific tissues (e.g., tissues affected by a disease, disorder or illness) or fluids (e.g., blood, saliva, serum, sweat, tears, urine). Those skilled in the art will understand that in some embodiments, a therapeutically effective amount can be formulated or administered in a single dose. In some embodiments, a therapeutically effective amount can be formulated or administered in multiple doses, for example, as part of a dosing regimen.
[0400] In order to be used as the treatment of a subject, the compound of the present invention or a pharmaceutically acceptable salt thereof can be formulated into a medicine or veterinary composition. Depending on the subject to be treated, the mode of administration and the desired type of treatment (e.g., prevention / prophylaxis or treatment), the compound or its pharmaceutically acceptable salt is formulated in a manner consistent with these parameters. An overview of such technology can be found in Remington: The Science and Practice of Pharmacy, 21st edition, Lippincott Williams & Wilkins, (2005); and Encyclopedia of Pharmaceutical Technology J. Swarbrick and JC Boylan, 1988-1999, Marcel Dekker, New York, each of which is incorporated herein by reference.
[0401] The composition can be prepared according to conventional mixing, granulation or coating methods, respectively, and the pharmaceutical composition of the present invention can 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 its pharmaceutically acceptable salt by weight or volume. In some embodiments, the compound described herein or its pharmaceutically acceptable salt can be present in an amount of 1%-95% by weight of the total weight of the composition (such as a pharmaceutical composition).
[0402] Composition can be suitable for intra-articular, oral, parenteral (such as intravenous, intramuscular), per rectum, percutaneous, subcutaneous, through surface, through dermal, sublingual, per nasal, per vaginal, intracapsular, intraurethral, intrathecal, epidural, through ear or through eye administration or by injection, suction or with the dosage form of nose, urogenital, reproduction or oral mucosa direct contact provide.Therefore, pharmaceutical composition can be in such as tablet, capsule, pill, powder, granule, suspension, emulsion, solution, comprise the gel of hydrogel, paste, ointment, emulsifiable paste, plaster, drench medicine, osmotic delivery device, suppository, enema, injection, implant, spray, be suitable for the preparation sent by iontophoresis or the form of aerosol.Composition can be prepared according to conventional medicine practice.
[0403] 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 bronchial (including by bronchial instillation), buccal, enteral, intradermal, intraarterial, intradermal, intragastric, intramedullary, intramuscular, intranasal, intraperitoneal, intrathecal, intravenous, intraventricular, mucosal, nasal, oral, rectal, subcutaneous, sublingual, topical, tracheal (including by intratracheal instillation), transdermal, vaginal, or vitreous.

[0486]
[0487] BRAF inhibitors that can be used in combination with the compounds of the present invention include, for example, vemurafenib, dabrafenib, and encorafenib. BRAF may comprise three types of BRAF mutations.

[0488] MCL-1 inhibitors include, but are not limited to, AMG-176, MIK665, and S63845. Myeloid cell leukemia-1 (MCL-1) protein is one of the major 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 not only to traditional chemotherapy but also to targeted therapeutics including BCL-2 inhibitors (such as ABT-263).
[0489] In some embodiments, the other therapeutic agent is a SHP2 inhibitor. 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. For example, stimulation by cytokines or growth factors that act through receptor tyrosine kinases (RTKs) exposes the catalytic site, leading to enzymatic activation of SHP2.
[0490] SHP2 participates in signal transduction through the RAS-mitogen-activated protein kinase (MAPK), JAK-STAT, or phosphoinositide 3-kinase-AKT pathways. Mutations in the PTPN11 gene and subsequently in SHP2 have been identified in several human developmental diseases (such as Noonan Syndrome and Leopard Syndrome) and 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 highly attractive target for the development of novel therapies for the treatment of various diseases, including cancer. The combination of SHP2 inhibitors (such as RMC-4550 or SHP099) with RAS pathway inhibitors (such as MEK inhibitors) has been shown to inhibit the proliferation of multiple cancer cell lines (such as pancreatic cancer, lung cancer, ovarian cancer, and breast cancer) in vitro.

[0608] In vitro and in vivo experiments:
[0609] The following assays can be performed to evaluate various properties of the compounds of the invention: Compounds A1-A6 herein exhibit (i) a pERK (Capan-1, K-Ras G12V) IC50 of less than 8 μM; (ii) a MOA (G13C) IC50 of less than 30 μM; or (iii) both (i) and (ii).
[0610] Potency assay: pERK
[0611] The purpose of this assay is to measure the ability of a test compound to inhibit K-Ras in cells. Activated K-Ras induces an increase in ERK phosphorylation at threonine 202 and tyrosine 204 (pERK). This procedure measures the decrease in cellular pERK in response to a test compound. The procedure described below in NCI-H358 cells is applicable to K-Ras G12C.
[0612] NOTE: This protocol can be performed with alternative cell lines to characterize inhibitors of other RAS variants, including, for example, AsPC-1 (K-Ras G12D), Capan-1 (K-Ras G12V), NCI-H1355 (K-Ras G13C), Hs 766T (K-Ras Q61H), NCI-H2347, or KU-19-19 (N-Ras Q61R), or SK-MEL-30 (N-Ras Q61K).
[0613] NCI-H358 cells were grown and maintained using ATCC recommended media and procedures. The day before compound addition, cells were plated in 384-well cell culture plates (40 μl / well) and grown overnight in a 37°C, 5% CO2 incubator. Test compounds were prepared in 10,3-fold dilutions in DMSO with a high concentration of 10 mM. On the day of the assay, the cells were quantified using an Echo 550 liquid handler. 40 nl of test compound was added to each well of the cell culture plate. Test compound concentrations were tested in duplicate. Following compound addition, the plate was shaken at 300 rpm for 15 seconds, centrifuged, and the cells were incubated at 37°C, 5% CO₂ for 4 hours. Following incubation, the culture medium was removed and the cells were washed once with phosphate-buffered saline.
[0614] In some experiments, cellular pERK levels were determined using the AlphaLISA SureFire Ultra p-ERK1 / 2 assay kit (PerkinElmer). Cells were lysed in 25 μl of lysis buffer and shaken at 600 RPM at room temperature. The lysate (10 μl) was transferred to a 384-well Opti-plate (PerkinElmer) and 5 μl of the receptor mixture was added. After incubation for 2 hours in the dark, 5 μl of the donor mixture was added, the plate was sealed and incubated for 2 hours at room temperature. The signal was read on an Envision plate reader (PerkinElmer) using a standard AlphaLISA setup. a) Raw data analysis was performed in Excel (Microsoft) and Prism (GraphPad). The signal was plotted against the logarithm of the compound concentration and the IC was determined by fitting a 4-parameter sigmoidal concentration response model or b) using Genedata Screener (Genedata). 50 Normalized signals were plotted against the logarithm of the compound concentration and IC50s were determined by fitting a 4-parameter sigmoidal concentration-response model.
[0615] In other experiments, cell pERK was determined by intracellular Western blotting (In-Cell Western). After compound treatment, cells were washed twice with 200 μl tris-buffered saline (TBS) and fixed with 150 μl of 4% paraformaldehyde in TBS for 15 minutes. Fixed cells were washed 4 times for 5 minutes with TBS (TBST) containing 0.1% Triton X-100, and then blocked with 100 μl Odyssey blocking buffer (LI-COR) for 60 minutes at room temperature. The first antibody (pERK, CST-4370, Cell Signaling Technology) was diluted 1: 200 in blocking buffer, and 50 μl was added to each well and incubated overnight at 4°C. Cells were washed 4 times with TBST for 5 minutes. Secondary antibody (IR-800CW rabbit, LI-COR, 1:800 dilution) and DNA stain DRAQ5 (LI-COR, 1:2000 dilution) were added and incubated at room temperature for 1-2 hours. The cells were washed 4 times with TBST for 5 minutes. The plates were scanned on a Li-COR Odyssey CLx imager. Raw data were analyzed in Excel (Microsoft) and Prism (GraphPad). The signal was plotted against the logarithm of the compound concentration and the IC was determined by fitting a 4-parameter sigmoidal concentration response model. 50 .
[0616] The compounds of the present invention have an inhibitory effect on the Ras binding domain of B-Raf (BRAF RBD ) disruption of the interaction with K-Ras (also known as MOA assay)
[0617] NOTE – The following protocol describes the methods used to monitor the effects of compounds of the invention on K-Ras G12C (GMP-PNP) and BRAF RBD This protocol can also be performed using other Ras proteins or nucleotide substitutions.
[0618] The purpose of this biochemical assay is to measure the ability of a test compound to induce the formation of a ternary complex between nucleotide-loaded K-Ras isoforms and cyclophilin A; the resulting ternary complex disrupts the binding of BRAF to RBD The binding of the construct to the K-Ras agonist inhibits K-Ras signaling through RAF effectors. Data are reported as IC50 values.
[0619] Untagged cyclophilin A, His6-K-Ras-GMPPNP and GST-BRAF were mixed in an assay buffer containing 25 mM HEPES pH 7.3, 0.002% Tween 20, 0.1% BSA, 100 mM NaCl and 5 mM MgCl2.RBD The compounds were combined in a 384-well assay plate at final concentrations of 25 μM, 12.5 nM, and 50 nM, respectively. Compounds were present in the wells of the culture plate in a 10-point, 3-fold dilution series starting at a final concentration of 30 μM. After incubation at 25°C for 3 hours, a mixture of anti-His Eu-W1024 and anti-GST allophycocyanin was added to the assay sample wells at final concentrations of 10 nM and 50 nM, respectively, and the reactions were incubated for an additional 1.5 hours. TR-FRET signals were read on a microplate reader (Ex 320 nm, Em 665 / 615 nm). Compounds that promote disruption of the K-Ras:RAF complex were identified as those that triggered a decrease in the TR-FRET ratio relative to the DMSO control wells.
