AI Technical Summary
Current KRAS G12C inhibitors primarily target the GDP-bound form of the protein, leading to limited efficacy and rapid resistance in cancer treatment, as cancer cells can increase GTP-bound KRAS levels, which are less affected by these inhibitors.
Development of pyrido[4,3-d]pyrimidine derivatives that bind to and inhibit both the inactive GDP- and activated GTP-bound forms of KRAS G12C, offering improved inhibition of the GTP-bound form.
The pyrido[4,3-d]pyrimidine derivatives provide enhanced therapeutic potential by effectively targeting both forms of KRAS G12C, potentially prolonging treatment response and reducing resistance in cancers characterized by this mutation.

PYRIDO[4,3-D]PYRIMIDINE DERIVATIVES AS MUTANT KRAS G12C INHIBITORS FOR THE TREATMENT OF CANCERCross-reference to related applications
[0001] This application claims priority to and benefit of U.S. Provisional Patent Application No. 63 / 464,191, filed on May 4, 2023, and U.S. Provisional Patent Application No. 63 / 615,742, filed on December 28, 2023, the disclosure of which is hereby incorporated herein by reference in its entirety.Field of the Disclosure
[0002] The present disclosure provides compounds useful in treating or suppressing cancer, and in particular, useful in treating or suppressing cancers characterized by the KRAS G12C mutant. Also provided are pharmaceutical formulations containing such compounds, processes for preparing such compounds, and methods of using such compounds in the treatment or suppression of cancers.Background
[0003] KRAS is a molecular switch. Under normal physiological conditions, the protein is bound to guanosine diphosphate (GDP) in the “off state.” In response to signaling through receptor tyrosine kinases (RTKs) such as EGFR, the GDP is exchanged to guanosine triphosphate (GTP) in a process facilitated by guanine nucleotide exchange factors (GEFs) such as SOS. The GTP-bound form of KRAS is in the “on state,” and interacts with proteins such as RAF and PI3K to promote downstream signaling that leads to cell proliferation and survival. KRAS can slowly hydrolyze GTP back to GDP, thus returning to the off-state, in a process facilitated by GAPs (GTPase- activating Proteins).
[0004] KRAS mutations are found in approximately 30% of all human cancers, and are highly prevalent among three of the deadliest forms of cancer: pancreatic (95%), colorectal (45%), and lung (35%). Together, these cancers occur in more than 200,000 patients annually in the US alone. One particular mutation, a glycine to cysteine substitution at position 12 (G12C), occurs in more than 40,000 patients per year. The KRAS G12C mutation impairs hydrolysis of GTP to GDP, thus trapping KRAS in the on-state and promoting cancer cell proliferation.
[0005] The cysteine residue of G12C provides an opportunity to develop targeted covalent drugs for this mutant KRAS. Early clinical trial results for KRAS G12C inhibitors AMG 510 and MRTX849 have shown encouraging results for non-small cell lung cancer (NSCLC), but the data are less compelling for colorectal cancer (CRC). Moreover, even in cases where patients respond to initial treatment, there are signs that the response may be limited in duration and that resistance could arise rapidly.
[0006] Most inhibitors of KRAS mutants bind preferentially to the GDP-bound form of the protein. For example, Amgen KRAS inhibitor AMG 510 and Mirati KRAS inhibitor MRTX849 react with the GDP-bound form of KRAS G12C at least 1000-fold more rapidly than with the GTP-bound form of the protein. One form of resistance that has been observed is for cancer cells to increase signaling through RTKs, thus increasing the amount of GTP-bound KRAS, which is less affected by current inhibitors. Thus, creating a molecule that could bind to and inhibit both the GDP- and GTP-bound forms of KRAS could have substantial utility.
[0007] What is needed are compounds useful in the treatment of cancer, such as cancers characterized by KRAS G12C. What is further needed are compounds useful in the treatment of cancers characterized by KRAS G12C, wherein the compounds bind to and inhibit both the inactive GDP- and activated GTP-bound forms of KRAS. What is further needed are compounds useful in the treatment of cancers characterized by KRAS G12C, wherein the compound has improved inhibition of the GTP-bound form of KRAS G12C. Summary

[0016] Provided herein are compounds useful in treating cancer, and methods of using such compounds for treating cancer. In some embodiments, the compounds are useful in treating cancers characterized by KRAS G12C. In some embodiments, the compounds advantageously inhibit both the inactive GDP- and activated GTP-bound forms of KRAS G12C. In some embodiments, the compounds advantageously have improved inhibition of the GTP-bound form of KRAS G12C. Definitions
[0017] The abbreviations used herein have their conventional meaning within the chemical and biological arts, unless otherwise specified.
[0018] It is to be understood that descriptions of compound structures, including possible substitutions, are limited to those which are chemically possible.
[0019] Unless otherwise indicated, the absolute stereochemistry of all chiral atoms is as depicted. The “Ex.”column of Table 1 indicates the synthetic example number corresponding to the structure provided in the same row of Table 1. A set of compounds, each with absolute stereochemistry in Table 1, may have multiple example numbers assigned in the “Ex.”column. Insuch case, each of the assigned examples produced just one of those compounds. However, the absolute stereochemistry of that compound has not been determined. For example, compounds 7-2 and 7-3 in Table 1 have “22 or 23”indicated in the “Ex.”column, meaning that just one of compounds 7-2 and 7-3 was obtained from Example 22 and just the other compound was obtained from Example 23. As another example, compounds 15-3, 15-4, 15-5, and 15-6 in Table 1 have “36 or 37”indicated in the “Ex.”column, meaning that just one of the four compounds was obtained from Example 36, and just one of the other three compounds was obtained from Example 37.
[0020] Compounds with an (and) designation in the stereochemistry column of Table 1 are mixtures of enantiomers wherein the relative stereochemistry is as shown. Compounds that have a stereogenic center where the configuration is not indicated in the structure as depicted and that have no designation in the Stereochemistry column of Table 1 are mixtures of enantiomers at that center. Compounds that have a stereogenic center where the configuration is indicated by bold wedges or hashed wedges in the structure, and that have no designation in the Stereochemistry column of Table 1 or that are marked with (abs) are single enantiomers wherein the absolute stereochemistry is as indicated.
[0021] For example, compoundsingle enantiomer with the stereochemistry as indicated.
[0022] A bold or hashed non-wedged (i.e., rectangular) bond in a compound indicates that the compound is a mixture of different diastereomers with fixed cis- or trans-configuration.
[0024] In some instances, the Stereochemistry column of Table 1 contains different indicators selected from (abs) and (and) to refer to different stereocenters or pairs of stereocenters of the molecule.
[0025] For example, “Amino-pyrrolidine – (abs)”for compound 27-1indicates that the amino-pyrrolidinyl headgroup of the compound has (R,R) configuration as drawn; and “R1– (and)”indicates that the R1group of the compound has either (R) or (S) stereochemistry such that the compound obtained from Example.
[0026] A person of skill in the art would be able to separate racemic compounds into the respective enantiomers using methods known in the art, such as chiral chromatography, chiral recrystallization and the like. References to compounds that are racemic mixtures are meant to also include the individual enantiomers contained in the mixture.
[0027] Reference to “about”a value or parameter herein includes (and describes) variations that are directed to that value or parameter per se. For example, description referring to “about X”includes description of “X”. As used herein, and unless otherwise specified, the terms “about”and “approximately,”when used in connection with temperatures, doses, amounts, or weight percent of ingredients of a composition or a dosage form, mean a dose, amount, or weight percent that is recognized by those of ordinary skill in the art to provide a pharmacological effect equivalent to that obtained from the specified dose, amount, or weight percent. Specifically, the terms “about”and “approximately,”when used in this context, contemplate a dose, amount, or weight percent within 15%, within 10%, within 5%, within 4%, within 3%, within 2%, within 1%, or within 0.5% of the specified dose, amount, or weight percent.
[0028] The terms “a”and “an,”as used in herein mean one or more, unless context clearly dictates otherwise.
[0029] The terms “subject,”“individual,”and “patient”mean an individual organism, preferably a vertebrate, more preferably a mammal, most preferably a human. Examples of patients include humans, livestock such as cows, goats, sheep, pigs, and rabbits, and companion animals such as dogs, cats, and horses. In some embodiments, the subject has been identified or diagnosed ashaving a cancer or tumor having a KRAS G12C mutation (e.g., as determined using a regulatory agency-approved, e.g., FDA-approved, assay or kit).
[0030] “Treating”a disorder with the compounds and methods discussed herein is defined as administering one or more of the compounds discussed herein, with or without additional therapeutic agents, in order to reduce or eliminate either the disorder or one or more symptoms of the disorder, or to retard the progression of the disorder or of one or more symptoms of the disorder, or to reduce the severity of the disorder or of one or more symptoms of the disorder.
[0031] “Suppression”of a disorder with the compounds and methods discussed herein is defined as administering one or more of the compounds discussed herein, with or without additional therapeutic agents, in order to suppress the clinical manifestation of the disorder, or to suppress the manifestation of adverse symptoms of the disorder. The distinction between treatment and suppression is that treatment occurs after adverse symptoms of the disorder are manifest in a subject, while suppression occurs before adverse symptoms of the disorder are manifest in a subject. Suppression may be partial, substantially total, or total. In some embodiments, genetic screening can be used to identify patients at risk of the disorder. The compounds and methods disclosed herein can then be administered to asymptomatic patients at risk of developing the clinical symptoms of the disorder, in order to suppress the appearance of any adverse symptoms.
[0032] “Therapeutic use”of the compounds discussed herein is defined as using one or more of the compounds discussed herein to treat or suppress a disorder, as defined herein. A “therapeutically effective amount”of a compound is an amount of the compound, which, when administered to a subject, is sufficient to reduce or eliminate either the disorder or one or more symptoms of the disorder, or to retard the progression of the disorder or of one or more symptoms of the disorder, or to reduce the severity of the disorder or of one or more symptoms of the disorder, or to suppress the clinical manifestation of a disorder, or to suppress the manifestation of adverse symptoms of a disorder. A therapeutically effective amount can be given in one or more administrations.
[0033] A “KRAS G12C mediated cancer”is used interchangeably herein with a “cancer characterized by KRAS G12C”, and indicates that the cancer comprises cells which contain the KRAS G12C mutant.
[0034] While the compounds described herein can occur and can be used as the neutral (non-salt) compound, the description is intended to embrace all salts of the compounds described herein, as well as methods of using such salts of the compounds. In some embodiments, the salts of the compounds comprise pharmaceutically acceptable salts.
[0035] A “pharmaceutically acceptable salt”of a compound means a salt that is pharmaceutically acceptable to humans and / or animals, and which, upon administration, retains at least some of the desired pharmacological activity of the parent compound. Such salts include: (a) acid addition salts, formed with inorganic acids such as hydrochloric acid, hydrobromic acid, sulfuric acid, nitric acid, phosphoric acid, and the like; or formed with organic acids such as formic acid, acetic acid, propionic acid, hexanoic acid, cyclopentanepropionic acid, glycolic acid, pyruvic acid, lactic acid, malonic acid, succinic acid, malic acid, maleic acid, fumaric acid, tartaric acid, citric acid, benzoic acid, 3-(4-hydroxybenzoyl)benzoic acid, cinnamic acid, mandelic acid, methanesulfonic acid, ethanesulfonic acid, 1,2-ethanedisulfonic acid, 2-hydroxyethanesulfonic acid, benzenesulfonic acid, 4-chlorobenzenesulfonic acid, 2-naphthalenesulfonic acid, 4-toluenesulfonic acid, camphorsulfonic acid, glucoheptonic acid, 4,4’-methylenebis-(3-hydroxy-2-ene-1-carboxylic acid), 3-phenylpropionic acid, trimethylacetic acid, tertiary butylacetic acid, lauryl sulfuric acid, gluconic acid, glutamic acid, hydroxynaphthoic acid, salicylic acid, stearic acid, muconic acid, and the like; or (b) salts formed when an acidic proton present in the parent compound either is replaced by a metal ion, e.g., an alkali metal ion, an alkaline earth ion, or an aluminum ion; or coordinates with an organic base such as ethanolamine, diethanolamine, triethanolamine, tromethamine, N-methylglucamine, and the like. Additional information on suitable pharmaceutically acceptable salts can be found in Remington’s Pharmaceutical Sciences, 17th ed., Mack Publishing Company, Easton, PA, 1985, which is incorporated herein by reference in its entirety.
[0036] Included herein, when chemically relevant, are all stereoisomers of the compounds, including diastereomers and enantiomers. Also included are mixtures of possible stereoisomers in any ratio, including, but not limited to, racemic mixtures. Unless stereochemistry is explicitly indicated in a structure, the structure is intended to embrace all possible stereoisomers of the compound depicted. If stereochemistry is explicitly indicated for one portion or portions of a molecule, but not for another portion or portions of a molecule, the structure is intended to embrace all possible stereoisomers for the portion or portions where stereochemistry is not explicitly indicated.
[0037] “Isotopologue”refers herein to a compound which differs in its isotopic composition from its “natural”isotopic composition. “Isotopic composition”refers to the amount of each isotope present for a given atom, and “natural isotopic composition”refers to the naturally occurring isotopic composition or abundance for a given atom. Atoms containing their natural isotopic composition may also be referred to herein as “non-enriched”atoms. Unless otherwise designated, the atoms of the compounds recited herein are meant to represent any stable isotope of that atom.For example, unless otherwise stated, when a position is designated specifically as “H”or “hydrogen,”the position is understood to have hydrogen at its natural isotopic composition. The description of compounds herein also includes all isotopologues, in some embodiments, partially deuterated or perdeuterated analogs, of all compounds herein. “Isotopically enriched”may also refer to a compound containing at least one atom having an isotopic composition other than the natural isotopic composition of that atom. “Isotopic enrichment”refers to the percentage of incorporation of an amount of a specific isotope at a given atom in a molecule in the place of that atom’s natural isotopic abundance. For example, deuterium enrichment of 1% at a given position means that 1% of the molecules in a given sample contain deuterium at the specified position. Because the naturally occurring distribution of deuterium is about 0.0156%, deuterium enrichment at any position in a compound synthesized using non-enriched starting materials is about 0.0156%. The isotopic enrichment of the compounds provided herein can be determined using conventional analytical methods known to one of ordinary skill in the art, including mass spectrometry and nuclear magnetic resonance spectroscopy.

A suitable dosage level may be about 0.01 to about 250 mg / kg per day, about 0.05 to about 100 mg / kg per day, or about 0.1 to about 50 mg / kg per day. Within this range the dosage can be about 0.05 to about 0.5, about 0.5 to about 5 or about 5 to about 50 mg / kg per day. For oral administration, the compositions can be provided in the form of tablets containing about 1.0 to about 1000 milligrams of the active ingredient, particularly about 1,5, 10, 15, 20, 25, 50, 75, 100, 150, 200, 250, 300, 400, 500, 600, 750, 800, 900, and 1000 milligrams of the active ingredient. The actual amount of a compound of this disclosure, i.e., the active ingredient, will depend upon numerous factors such as the severity of the disease to be treated, the age and relative health of the patient, the potency of the compound being utilized, the route and form of administration, and other factors.
[0155] In general, compounds of this disclosure will be administered as pharmaceutical compositions by any one of the following routes: oral, systemic (e.g., transdermal, intranasal or by suppository), or parenteral (e.g., intramuscular, intravenous or subcutaneous) administration. The preferred manner of administration is oral using a convenient daily dosage regimen, which can be adjusted according to the degree of affliction. Compositions can take the form of tablets, pills, capsules, semisolids, powders, sustained release formulations, solutions, suspensions, elixirs, aerosols, or any other appropriate compositions.
[0156] The choice of formulation depends on various factors such as the mode of drug administration (e.g., for oral administration, formulations in the form of tablets, pills or capsules, including enteric coated or delayed release tablets, pills or capsules are preferred) and the bioavailability of the drug substance.
[0157] The compositions are comprised of in general, a compound of this disclosure in combination with at least one pharmaceutically acceptable excipient. Acceptable excipients are non-toxic, aid administration, and do not adversely affect the therapeutic benefit of the compound of this disclosure. Such excipient may be any solid, liquid, semi-solid or, in the case of an aerosol composition, gaseous excipient that is generally available to one of skill in the art.
[0158] Solid pharmaceutical excipients include starch, cellulose, talc, glucose, lactose, sucrose, gelatin, malt, rice, flour, chalk, silica gel, magnesium stearate, sodium stearate, glycerol monostearate, sodium chloride, dried skim milk and the like. Liquid and semisolid excipients may be selected from glycerol, propylene glycol, water, ethanol and various oils, including those of petroleum, animal, vegetable or synthetic origin, e.g., peanut oil, soybean oil, mineral oil, sesame oil, etc. Preferred liquid carriers, particularly for injectable solutions, include water, saline, aqueous dextrose, and glycols.
[0159] The compounds may be formulated for parenteral administration by injection, e.g., by bolus injection or continuous infusion. Formulations for injection may be presented in unit dosage form, e.g., in ampoules or in multi-dose containers, with an added preservative. The compositions may take such forms as suspensions, solutions or emulsions in oily or aqueous vehicles, and may contain formulatory agents such as suspending, stabilizing and / or dispersing agents. The formulations may be presented in unit-dose or multi-dose containers, for example sealed ampoulesand vials, and may be stored in powder form or in a freeze-dried (lyophilized) condition requiring only the addition of the sterile liquid carrier, for example, saline or sterile pyrogen-free water, immediately prior to use. Extemporaneous injection solutions and suspensions may be prepared from sterile powders, granules and tablets of the kind previously described.
[0160] Formulations for parenteral administration include aqueous and non-aqueous (oily) sterile injection solutions of the active compounds which may contain antioxidants, buffers, bacteriostats and solutes which render the formulation isotonic with the blood of the intended recipient; and aqueous and non-aqueous sterile suspensions which may include suspending agents and thickening agents. Suitable lipophilic solvents or vehicles include fatty oils such as sesame oil, or synthetic fatty acid esters, such as ethyl oleate or triglycerides, or liposomes. Aqueous injection suspensions may contain substances which increase the viscosity of the suspension, such as sodium carboxymethyl cellulose, sorbitol, or dextran. Optionally, the suspension may also contain suitable stabilizers or agents which increase the solubility of the compounds to allow for the preparation of highly concentrated solutions.
[0161] In addition to the formulations described previously, the compounds may also be formulated as a depot preparation. Such long acting formulations may be administered by implantation (for example subcutaneously or intramuscularly) or by intramuscular injection. Thus, for example, the compounds may be formulated with suitable polymeric or hydrophobic materials (for example as an emulsion in an acceptable oil) or ion exchange resins, or as sparingly soluble derivatives, for example, as a sparingly soluble salt.
[0162] For buccal or sublingual administration, the compositions may take the form of tablets, lozenges, pastilles, or gels formulated in conventional manner. Such compositions may comprise the active ingredient in a flavored basis such as sucrose and acacia or tragacanth.
[0163] The compounds may also be formulated in rectal compositions such as suppositories or retention enemas, e.g., containing conventional suppository bases such as cocoa butter, polyethylene glycol, or other glycerides.
[0164] Certain compounds of the disclosure may be administered topically, that is by non- systemic administration. This includes the application of the compounds externally to the epidermis or the buccal cavity and the instillation of such compounds into the ear, eye and nose, such that the compound does not significantly enter the blood stream. In contrast, systemic administration refers to oral, intravenous, intraperitoneal and intramuscular administration.
[0165] Formulations suitable for topical administration include liquid or semi-liquid preparations suitable for penetration through the skin to the site of inflammation such as gels, liniments, lotions, creams, ointments or pastes, and drops suitable for administration to the eye, ear or nose.The active ingredient for topical administration may comprise, for example, from 0.001% to 10% w / w (by weight) of the formulation.
