Abstract
Description
Field of the Invention
[0001] The present disclosure generally relates to novel compounds useful as inhibitors of the KRAS protein, as well as pharmaceutical compositions comprising these compounds, and methods of treatment by administering these compounds or the pharmaceutical compositions. Background Art
[0002] The KRAS oncoprotein is a GTPase and a fundamental mediator of intracellular signaling pathways involved in tumor cell growth and survival. In normal cells, KRAS acts as a molecular switch, switching between an inactive GDP-bound state and an active GTP-bound state. The transition between these states is promoted by a guanine nucleotide exchange factor that loads GTP and activates KRAS and GTP hydrolysis, which is catalyzed by GTPase-activated proteins to inactivate KRAS. GTP bound to KRAS promotes the binding of effectors to trigger signal transduction pathways including the RAF-MEK-ERK (MAPK) pathway.
[0003] Activating mutations in KRAS are a hallmark of cancer and prevent the association of GTPase-activated proteins, thereby stabilizing effector binding and enhancing KRAS signaling. KRAS G12C is present in approximately 13% of lung adenocarcinomas, 3% of colorectal cancers, and 2% of other solid tumors. Therefore, KRAS, and KRAS G12C in particular, is widely considered a particularly important oncology target.
[0004] Although progress has been made in targeting KRAS G12C, targeting this gene with small molecules remains a challenge. Therefore, there is a need in the art to develop improved small molecule compounds that inhibit KRAS, particularly KRAS G12C. Summary of the Invention
[0005] The present disclosure provides compounds capable of modulating KRAS G12C protein, including stereoisomers, pharmaceutically acceptable salts, tautomers, and prodrugs thereof, and methods of using such compounds to treat various diseases or conditions, such as cancer, are also provided.

All references cited in the present disclosure, patents, patent applications, are hereby incorporated by reference in their entirety.
[0055] It should be understood that certain features of the present disclosure, which are, for clarity, described in the context of separate embodiments, can also be provided in combination in a single embodiment.

[0210] The compounds provided herein are described with reference to both general formulae and specific compounds. Additionally, the compounds of the present disclosure may exist in a variety of different forms or derivatives, including but not limited to prodrugs, soft drugs, active metabolic derivatives (active metabolites), and pharmaceutically acceptable salts thereof, all of which are within the scope of the present disclosure.
[0211] As used herein, the term "prodrug" refers to a compound or a pharmaceutically acceptable salt thereof that, when metabolized under physiological conditions or converted by dissolution, produces the desired active compound. Prodrugs include, but are not limited to, esters, amides, carbamates, carbonates, urea, solvates, or hydrates of the active compound. Typically, a prodrug is inactive or less active than the active compound but may provide one or more advantageous handling, administration, and / or metabolic properties. For example, some prodrugs are esters of the active compound; during metabolic dissolution, the ester group is cleaved to yield the active drug. In addition, some prodrugs are enzymatically activated to produce the active compound or produce the active compound upon further chemical reaction. A prodrug may be converted from the prodrug form to the active form in a single step, or may have one or more intermediate forms that may themselves be active or inactive. The preparation and use of prodrugs are discussed in T. Higuchi and V. Stella, “Pro-drugs as Novel Delivery Systems”, volume 14 of the ACSSymposium Series, in Bioreversible Carriers in Drug Design, ed. Edward B. Roche, American Pharmaceutical Association and Pergamon Press, 1987; in Prodrugs: Challenges and Rewards, ed. V. Stella, R. Borchardt, M. Hageman, R. Oliyai, H. Maag, J. Tilley, Springer-Verlag New York, 2007, all of which are hereby incorporated by reference in their entirety.
[0212] As used herein, the term "soft drug" refers to a compound that exerts a pharmacological effect but breaks down into inactive metabolite degradation products so that the activity is of limited duration. See, for example, "Soft drugs: Principles and methods for the design of safe drugs" Nicholas Bodor, Medicinal Research Reviews, Vol. 4, No. 4, 449-469, 1984, which is hereby incorporated by reference in its entirety.
[0213] As used herein, the term "metabolite", for example, an active metabolite overlaps with a prodrug as described above. Thus, such metabolites are pharmacologically active compounds or compounds that are further metabolized into pharmacologically active compounds (which are derivatives produced by metabolic processes in the body of an individual). For example, such metabolites can be produced by oxidation, reduction, hydrolysis, amidation, deamidation, esterification, deesterification, enzymatic cleavage, etc. of the administered compound or salt or prodrug. Among them, active metabolites are such pharmacologically active derivative compounds. For prodrugs, the prodrug compound is generally inactive or less active than the metabolite. For active metabolites, the parent compound may be an active compound or may be an inactive prodrug.
[0214] Prodrugs and active metabolites can be identified using routine techniques known in the art. See, for example, Bertolini et al., 1997, J Med Chem 40:2011-2016; Shan et al., J Pharm Sci 86:756-757; Bagshawe, 1995, Drug Dev Res 34:220-230; Wermuth, supra.
[0215] As used herein, the term "pharmaceutically acceptable" indicates that the substance or composition is chemically and / or toxicologically compatible with the other ingredients comprising the formulation and / or the subject being treated therewith.
[0216] Unless otherwise indicated, as used herein, the term "pharmaceutically acceptable salt" includes salts that retain the biological effectiveness of the free acids and bases of the specified compound and are not biologically or otherwise undesirable. Pharmaceutically acceptable salt forms encompassed include, but are not limited to, mono-, di-, tri-, tetra-salts, and the like. Pharmaceutically acceptable salts are non-toxic in the amounts and concentrations to which they are administered. The preparation of such salts can facilitate pharmacological use by altering their physical characteristics without hindering the compound from exerting its physiological effects. Applicable changes in physical properties include lowering the melting point for ease of transmucosal administration and increasing solubility for ease of administration of higher concentrations of the drug.
[0217] Pharmaceutically acceptable salts include acid addition salts, such as those containing the following acid addition salts: sulfate, chloride, hydrochloride, fumarate, maleate, phosphate, sulfamate, acetate, citrate, lactate, tartrate, methanesulfonate, ethanesulfonate, benzenesulfonate, p-toluenesulfonate, cyclohexylsulfamate and quinate. Pharmaceutically acceptable salts can be obtained, for example, from the following acids: hydrochloric acid, maleic acid, sulfuric acid, phosphoric acid, sulfamic acid, acetic acid, citric acid, lactic acid, tartaric acid, malonic acid, methanesulfonic acid, ethanesulfonic acid, benzenesulfonic acid, p-toluenesulfonic acid, cyclohexylsulfamate, fumaric acid and quinic acid.
[0218] When an acidic functional group is present, such as a carboxylic acid or phenol, pharmaceutically acceptable salts also include base addition salts, such as those containing benzophenone, chloroprocaine, choline, diethanolamine, ethanolamine, tert-butylamine, ethylenediamine, meglumine, procaine, aluminum, calcium, lithium, magnesium, potassium, sodium, ammonium, alkylamines, and zinc. For example, see Remington's Pharmaceutical Sciences, 19th edition, Mack Publishing Co., Easton, PA, Vol. 2, p. 1457, 1995; "Handbook of Pharmaceutical Salts: Properties, Selection, and Use" by Stahland Wermuth, Wiley-VCH, Weinheim, Germany, 2002. Such salts can be prepared using the appropriate corresponding base.
[0219] Pharmaceutically acceptable salts can be prepared by standard techniques. For example, the free base form of the compound can be dissolved in a suitable solvent (e.g., an aqueous or aqueous-alcoholic solution containing a suitable acid) and then isolated by evaporation of the solution. Thus, if the particular compound is a base, the desired pharmaceutically acceptable salt can be prepared by any suitable method available in the art, such as treating the free base with an inorganic acid (e.g., hydrochloric acid, hydrobromic acid, sulfuric acid, nitric acid, phosphoric acid, etc.) or with an organic acid (e.g., acetic acid, maleic acid, succinic acid, mandelic acid, fumaric acid, malonic acid, pyruvic acid, oxalic acid, glycolic acid, salicylic acid, pyranose acid (e.g., glucuronic acid or galacturonic acid), α-hydroxy acid (e.g., citric acid or tartaric acid), amino acid (e.g., aspartic acid or glutamic acid), aromatic acid (e.g., benzoic acid or cinnamic acid), sulfonic acid (e.g., p-toluenesulfonic acid or ethanesulfonic acid), etc.).
[0220] Similarly, if the particular compound is an acid, the desired pharmaceutically acceptable salt may be prepared by any suitable method, for example, by treating the free acid with an inorganic or organic base, such as an amine (primary, secondary or tertiary), an alkali metal hydroxide or an alkaline earth metal hydroxide, or the like. Illustrative examples of suitable salts include organic salts derived from amino acids such as L-glycine, L-lysine and L-arginine, ammonia, primary, secondary and tertiary amines, and cyclic amines such as hydroxyethylpyrrolidine, piperidine, morpholine and piperazine, and inorganic salts derived from sodium, calcium, potassium, magnesium, manganese, iron, copper, zinc, aluminum and lithium.
[0221] It will also be understood that the compounds of the present disclosure may exist in unsolvated forms, solvated forms (eg, hydrated forms), and solid forms (eg, crystalline or polymorphic forms), and that the present disclosure is intended to encompass all such forms.
[0222] As used herein, the term "solvate" or "solvated form" refers to a solvent addition form containing either stoichiometric or non-stoichiometric amounts of solvent. Some compounds have a tendency to trap a fixed molar ratio of solvent molecules in the crystalline solid state, thereby forming a solvate. If the solvent is water, the solvate formed is a hydrate; and if the solvent is an alcohol, the solvate formed is an alcoholate. Hydrates are formed by combining one or more molecules of water with one molecule of a substance, wherein the water retains its molecular state as HO. Examples of solvents that form solvates include, but are not limited to, water, isopropanol, ethanol, methanol, DMSO, ethyl acetate, acetic acid, and ethanolamine.
[0223] As used herein, the terms "crystal form," "crystalline form," "polymorphic form," and "polymorph" are used interchangeably and refer to crystal structures in which a compound (or a salt or solvate thereof) can crystallize in different crystal packing configurations, all having the same elemental composition. Different crystal forms typically have different X-ray diffraction patterns, infrared spectra, melting points, density, hardness, crystal shape, optical and electrical properties, stability, and solubility. Recrystallization solvent, crystallization rate, storage temperature, and other factors can cause one crystal form to dominate. Crystal polymorphs of a compound can be prepared by crystallization under different conditions.
[0224] The present disclosure is also intended to include all isotopes of atoms in the compounds. Isotopes of atoms include atoms with the same atomic number but different mass numbers. For example, unless otherwise specified, hydrogen, carbon, nitrogen, oxygen, phosphorus, sulfur, fluorine, chlorine, bromine, or iodine in the compounds of the present disclosure are also intended to include their isotopes, such as (but not limited to) 1 H. 2 H. 3 H. 11 C. 12 C. 13 C.14 C. 14 N. 15 N. 16 O. 17 O. 18 O. 31 P. 32 P. 32 S. 33 S. 34 S. 36 S. 17 F. 18 F. 19 F. 35 Cl, 37 Cl, 79 Br, 81 Br, 124 I. 127 I and 131 1. In some embodiments, hydrogen includes protium, deuterium, and tritium. In some embodiments, carbon includes 12 C and 13 C.
[0225] Those skilled in the art will appreciate that the compounds of the present disclosure can exist in different tautomeric forms, and all such forms are encompassed within the scope of the present disclosure. The term "tautomer" or "tautomeric form" refers to structural isomers with different energies that can be mutually converted via a low energy barrier. The presence and concentration of the isomeric forms will depend on the environment in which the compound exists, and may vary depending on, for example, whether the compound is solid or in an organic or aqueous solution form. By way of example, proton tautomers (also referred to as prototropic tautomers) include interconversions via migration of protons, such as keto-enol, amide-imidic acid, lactam-lactim, imine-enamine isomerization, and cyclic forms, wherein the proton can occupy two or more positions in the heterocyclic ring system. Valence tautomers include interconversions performed by the reorganization of some bonding electrons. Tautomers can be in equilibrium or stereo locked into one form by appropriate substitution. Unless otherwise stated, compounds of the present disclosure identified as a specific tautomeric form by name or structure are intended to include other tautomeric forms.

[0227] The compounds provided herein, including the synthesis of pharmaceutically acceptable salts thereof, are described in the synthesis processes in the examples. The compounds provided herein can be prepared using any known organic synthesis technique and can be synthesized according to any of a variety of possible synthetic pathways, and therefore these processes are merely exemplary and are not intended to limit other possible methods for preparing the compounds provided herein. In addition, the steps in the process are for preferred illustration and can be changed when appropriate. For the purpose of research and potentially submitting to regulatory agencies, embodiments of the compounds in the examples are synthesized.
[0228] The reaction for preparing the compound of the present disclosure can be carried out in a suitable solvent, and the solvent can be easily selected by a person skilled in the art. Suitable solvents can be generally not reacted with starting material (reactant), intermediate or product at a temperature within the range of solvent freezing temperature to solvent boiling temperature, for example. The specified reaction can be carried out in a solvent or a mixture of more than one solvent. Depending on the specific reaction step, the suitable solvent for the specific reaction step can be selected by a person skilled in the art.
