TETRACYCLIC DERIVATIVES AS K-Ras G12D INHIBITORS
[0001] Field of the disclosure
[0002] The present disclosure provides certain tetracyclic derivatives that inhibit K-Ras G12D and are therefore useful for the treatment of cancers mediated by it. Also provided are pharmaceutical compositions containing such compounds and processes for preparing such compounds.Background
[0003] Kirsten Rat Sarcoma 2 Viral Oncogene Homolog (KRAS) gene is a prevalent oncogene that encodes a small GTPase transductor protein called K-Ras. K-Ras can serve as a molecular switch by cyling between active GTP-bound and inactive GDP-bound forms (see Science 2001; 294: 1299–304. ) . K-Ras signaling is activated by RAS guanine nucleotide exchange factors (GEFs) , e.g., Son of Sevenless homologue (SOS) protein, that facilitate the GDP to GTP exchange of K-Ras (see Curr Biol 2005; 15: 563–74. ) . The interaction between K-Ras and GTPase-activating proteins (GAPs) such as p120GAP and neurofibromin, potentiates K-Ras intrinsic GTPase activity and accelerates GTP hydrolysis and diminishes K-Ras signaling (see Curr. Biol. 2005; 15: 563–74. ) .
[0004] K-Ras plays a crucial role in the regulation of cell proliferation, differentiation and survival by signaling through several major downstream pathways, including the MAPK, the PI3K and the Ral-GEFs pathways (see Lung Cancer 2018; 124: 53–64) , among them the MAPK pathway is the best characterized (see Mol. Cell Biol. 1995; 15: 6443–6453. ) . K-Ras-GTP binds to and activates RAF kinases, which phosphorylates MEK and subsequently phosphorylates ERK. Phospho-ERK can further activate downstream cytosolic proteins, which then translocate to the nucleus to drive the expression of diverse genes, propagating the growth signal.
[0005] PI3K pathway is also involved in RAS-mediated tumorigenesis (see Cell 2007; 129: 957–968. ) . Upon activation by K-Ras-GTP, PI3K phosphorylates PIP2 to form PIP3, activates PDK1 and then phosphorylates AKT. pAKT yields phosphorylation of several physiological substrates, e.g., mTOR, FOXO and NF-κB that promote metabolism, cell-cycle progression, resistance to apoptosis, cell survival and migration. The Ral-GEFs signaling pathway plays a key role in RAS-mediated oncogenesis as well (see Proc. Natl. Acad. Sci. U.S.A. 1994; 91: 11089–11093. ) . The K-Ras effector, RALGDS, stimulates the RAS family RAL-A / B small GTPases for the subsequent signaling cascades. RALGDS can also promote the JNK pathway to stimulate transcription of pro-survival and cell-cycle progression genes for cell proliferation and survival.
[0006] KRAS gene is the most frequently mutated oncogene in human cancer. KRAS mutations are associated with poor clinical outcome and found at high frequency in pancreatic cancer (~90%) , colorectal cancer (~44%) and non-small-cell lung cancer (NSCLC) (~29%) (see Cancer Discov. 2021; 11: 1–16) . KRAS mutations are also present in breast cancer, liver cancer, biliary tract malignancies, endometrial cancer, cervical cancer, bladder cancer and myeloid leukemia. The most common KRAS mutations are observed at residues G12 (77%) , G13 (10%) , and Q61 (6%) , and the most predominant KRAS variant in human malignancies is G12D (35%) , followed by G12V (29%) , G12C (21%) , G12A (7%) , G12R (5%) , and G12S (3%) (see Cancer Discov. 2021; 11: 1-16) . These mutations perturbate GTP hydrolysis of K-Ras by interfering with GAP binding / stimulation and / or reducing K-Ras intrinsic GTPase activity, resulting in constitutive activation of the protein and K-Ras signaling.
[0007] Targeting KRAS signaling has been a long pursuit in drug discovery. Among KRAS mutants, K-Ras G12C offers special opportunity, because it harbors a non-native cysteine residue, which can act as nucleophile and therefore can be targeted by covalent attachment. Besides AMG510 andMRTX849, which are approved drugs for treating K-Ras G12C driven cancers, several other K-Ras G12C covalent inhibitors, including GDC6036, JDQ443, RMC-6291 and LY349944631, are in clinical trials for treating cancer patients with KRAS G12C mutation (see ACS Cent. Sci. 2020; 6: 1753-1761) . These compounds ocuppy a dynamic pocket in the switch II region of K-Ras thereby irreversibly locking K-Ras G12C in inactive GDP-bound state
[0008] Given the role of K-Ras mutants in human malignancy, there is still unmet medical need for development of new treatments for cancer patients with other than G12C KRAS mutant. The present disclosure fulfills this and related needs.Summary

[0027] Definitions:
[0028] Unless otherwise stated, the following terms used in the specification and claims are defined for the purposes of this Application and have the following meaning:
[0029] A “pharmaceutically acceptable salt” of a compound means a salt that is pharmaceutically acceptable and that possesses the desired pharmacological activity of the parent compound. Such salts include:
[0030] 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
[0031] 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. It is understood that the pharmaceutically acceptable salts are non-toxic. 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.
[0032] The compounds of (or any embodiment thereof hereinbelow) may also contain unnatural amounts of isotopes at one or more of the atoms that constitute such compounds. Unnatural amounts of an isotope may be defined as ranging from the amount found in nature to an amount 100%of the atom in question, that differ only in the presence of one or more isotopically enriched atoms. Exemplary isotopes that can be incorporated into a compound of (or any embodiment thereof hereinbelow) include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorus, sulfur, fluorine, chlorine, and iodine, such as 2H, 3H, 11C, 13C, 14C, 13N, 15N, 15O, 17O, 18O, 32P, 33P, 35S, 18F, 36Cl, 123I, and 1251, respectively. Isotopically labeled compounds (e.g., those labeled with 3H and 14C) can be useful in compound or substrate tissue distribution assays. Tritiated (i.e., 3H) and carbon-14 (i.e., 14C) isotopes can be useful for their ease of preparation and detectability. Further, substitution with heavier isotopes such as deuterium (i.e., 2H) may afford certain therapeutic advantages resulting from greater metabolic stability (e.g., increased in vivo half-life or reduced dosage requirements) . In some embodiments, in compounds of (or any embodiment thereof hereinbelow) one or more hydrogen atoms are replaced by 2H or 3H, or one or more carbon atoms are replaced by 13C-or 14C-enriched carbon. Positron emitting isotopes such as 15O, 13N, 11C, and 15F are useful for positron emission tomography (PET) studies to examine substrate receptor occupancy. Isotopically labeled compounds can generally be prepared by following procedures analogous to those disclosed in the Schemes or in the Examples herein, by substituting an isotopically labeled reagent for a non-isotopically labeled reagent.
[0033] A “pharmaceutically acceptable carrier or excipient” means a carrier or an excipient that is useful in preparing a pharmaceutical composition that is generally safe, non-toxic and neither biologically nor otherwise undesirable, and includes a carrier or an excipient that is acceptable for veterinary use as well as human pharmaceutical use.
[0034] “A pharmaceutically acceptable carrier / excipient” as used in the specification and claims includes both one and more than one such excipient.
[0035] The term “disease” as used herein is intended to be generally synonymous, and is used interchangeably with, the terms “disorder, ” “syndrome, ” and “condition” (as in medical condition) , in that all reflect an abnormal condition of the human or animal body or of one of its parts that impairs normal functioning, is typically manifested by distinguishing signs and symptoms, and causes the human or animal to have a reduced duration or quality of life.
[0036] The term “combination therapy” means the administration of two or more therapeutic agents to treat a disease or disorder described in the present disclosure. Such administration encompasses co-administration of these therapeutic agents in a substantially simultaneous manner, such as in a single capsule having a fixed ratio of active ingredients or in multiple, separate capsules for each active ingredient. In addition, such administration also encompasses use of each type of therapeutic agent in a sequential manner. In either case, the treatment regimen will provide beneficial effects of the drug combination in treating the conditions or disorders described herein.
[0037] The term “patient” is generally synonymous with the term “subject” and includes all mammals including humans. Examples of patients include humans, livestock such as cows, goats, sheep, pigs, and rabbits, and companion animals such as dogs, cats, rabbits, and horses. Preferably, the patient is a human.
[0038] “Treating” or “treatment” of a disease includes:
[0039] (1) preventing the disease, i.e., causing the clinical symptoms of the disease not to develop in a mammal that may be exposed to or predisposed to the disease but does not yet experience or display symptoms of the disease;
[0040] (2) inhibiting the disease, i.e., delaying, arresting (i.e., stabilizing) , or reducing the development or severity of the disease or its clinical symptoms; or
[0041] (3) relieving the disease, i.e., causing regression of the disease or its clinical symptoms.
[0042] In one embodiment, treating or treatment of a disease includes inhibiting the disease, i.e., delaying, arresting or reducing the development or severity of the disease or its clinical symptoms; or relieving the disease, i.e., causing regression of the disease or its clinical symptoms.
[0043] A “therapeutically effective amount” means the amount of a compound of the present disclosure or a pharmaceutically acceptable salt thereof that, when administered to a patient for treating a disease, is sufficient to affect such treatment for the disease. The “therapeutically effective amount” will vary depending on the compound, the disease and its severity and the age, weight, etc., of the mammal to be treated. The therapeutically effective amount of a K-ras inhibitor disclosed herein can be administered to the patient in a single dosage form or multiples thereof. For example, 600 mg dose of a K-ras inhibitor can be administered in a single 600 mg tablet or two 300 mg tablets.
[0044] The terms "inhibiting" and "reducing, " or any variation of these terms in relation of K-Ras G12D, includes any measurable decrease or complete inhibition to achieve a desired result. For example, there may be a decrease of about, at most about, or at least about 5%, 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, 99%, or more, or any range derivable therein, reduction of K-Ras G12D GTPase activity; a decrease of K-Ras G12D GTP binding affinity or an increase of G12D GDP binding affinity; an increase of GTP off rate or a decrease of GDP off rate; a decrease of signaling transduction molecules levels downstream in the K-Ras pathway, e.g., a decrease in pERK level; and / or a decrease of K-Ras complex binding to downstream signaling molecules compared to normal.

[0054] Pharmaceutical Compositions
[0055] In general, the compounds of Table I (unless stated otherwise, reference to compound / compounds of Table I herein includes embodiments thereof and a pharmaceutically acceptable salt thereof) will be administered in a therapeutically effective amount by any of the accepted modes of administration for agents that serve similar utilities. Therapeutically effective amounts of compounds of Table I may range from about 0.01 to about 500 mg per kg patient body weight per day, which can be administered in single or multiple doses. A suitable dosage level may be from about 0.1 to about 250 mg / kg per day; about 0.5 to about 100 mg / kg per day. 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 or capsules 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 Table I 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.
[0056] In general, compounds of Table I 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.
[0057] 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.
[0058] The compositions are comprised of in general, a compound of Table I in combination with at least one pharmaceutically acceptable excipient. Acceptable excipients are generally non-toxic, aid administration, and do not adversely affect the therapeutic benefit of the compounds of Table I. 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.
[0059] 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.
[0060] Compounds of Table I 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 ampoules and 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.
[0061] 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.
[0062] In addition to the formulations described previously, the compounds of Table I 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.
[0063] 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.
[0064] Compounds of Table I 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.
[0065] Certain compounds of Table I may be administered topically, that is by non-systemic administration. This includes the application of a compound of Table I externally to the epidermis or the buccal cavity and the instillation of such a compound 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.
[0066] 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. In certain embodiments, the active ingredient may comprise as much as 10%w / w. In other embodiments, it may comprise less than 5%w / w. In certain embodiments, the active ingredient may comprise from 2%w / w to 5%w / w. In other embodiments, it may comprise from 0.1%to 1%w / w of the formulation.
[0067] For administration by inhalation, compounds of Table I may be conveniently delivered from an insufflator, nebulizer pressurized packs or other convenient means of delivering an aerosol spray. Pressurized packs may comprise a suitable propellant such as dichlorodifluoromethane, trichlorofluoromethane, dichlorotetrafluoroethane, carbon dioxide or other suitable gas. In the case of a pressurized aerosol, the dosage unit may be determined by providing a valve to deliver a metered amount. Alternatively, for administration by inhalation or insufflation, the compounds of Table I may take the form of a dry powder composition, for example a powder mix of the compound and a suitable powder base such as lactose or starch. The powder composition may be presented in unit dosage form, in for example, capsules, cartridges, gelatin or blister packs from which the powder may be administered with the aid of an inhalator or insufflator. Other suitable pharmaceutical excipients and their formulations are described in Remington’s Pharmaceutical Sciences, edited by E. W. Martin (Mack Publishing Company, 20th ed., 2000) .
[0068] The level of a compound of Table I in a formulation can vary within the full range employed by those skilled in the art. Typically, the formulation will contain, on a weight percent (wt. %) basis, from about 0.01-99.99 wt. %of a compound of Table I based on the total formulation, with the balance being one or more suitable pharmaceutical excipients. For example, the compound is present at a level of about 1-80 wt. %.
[0069] Combinations and Combination Therapies
[0070] Compounds of Table I (unless stated otherwise, reference to compound / compounds of Table I herein includes embodiments thereof) or a pharmaceutically acceptable salt thereof may be used in combination with one or more other drugs in the treatment of diseases or conditions for which the compounds of Table I or the other drugs may have utility. Such other drug (s) may be administered, by a route and in an amount commonly used therefore, contemporaneously or sequentially with a compound of Table I or a pharmaceutically acceptable salt thereof.
