[0002] The present disclosure provides compounds, as well as compositions and methods of use thereof, that modulate KRAS activity and are useful in the treatment of a variety of diseases, including cancer. [Background technology]
[0003] Ras proteins are part of a family of small GTPases that are activated by growth factors and various extracellular stimuli. The Ras family regulates intracellular signaling pathways that are involved in cell growth, migration, survival, and differentiation. Activation of RAS proteins in the cell membrane leads to the binding of key effectors and the initiation of a cascade of intracellular signaling pathways within the cell, including the RAF and PI3K kinase pathways. Somatic mutations in RAS can lead to uncontrolled cell growth and malignant transformation, while activation of RAS proteins is tightly regulated in normal cells (Simanshu, D. et al. Cell 170.1 (2017): 17-33).
[0004] The Ras family consists of three members: KRAS, NRAS, and HRAS. RAS-mutated cancers account for approximately 25% of human cancers. KRAS is the most frequently mutated isoform, accounting for 85% of all RAS mutations, while NRAS and HRAS are mutated in 12% and 3% of all RAS-mutated cancers, respectively (Simanshu, D. et al. Cell 170.1 (2017): 17-33). KRAS mutations are prevalent among the top three most lethal types of cancer: pancreatic (97%), colorectal (44%), and lung (30%) (Cox, AD et al. Nat Rev Drug Discov (2014) 13: 828-51). The majority of RAS mutations occur at amino acid residues 12, 13, and 61. The frequency of certain mutations varies between RAS gene isoforms, with G12 and Q61 mutations predominating in KRAS and NRAS, respectively, and G12, G13 and Q61 mutations occurring most frequently in HRAS. Furthermore, the spectrum of mutations in RAS isoforms differs between cancer types. For example, KRAS G12D mutations predominate in pancreatic cancer (51%), followed by colorectal adenocarcinoma (45%) and lung cancer (17%), while KRAS G12V mutations are associated with pancreatic cancer (30%), followed by colorectal adenocarcinoma (27%) and lung adenocarcinoma (23%) (Cox, AD et al. Nat Rev Drug Discov (2014) 13:828-51). In contrast, KRAS G12C mutations predominate in non-small cell lung cancer (NSCLC), accounting for 11-16% of lung adenocarcinomas and 2-5% of pancreatic and colorectal adenocarcinomas (Cox, AD et al. Nat. Rev. Drug Discov. (2014) 13:828-51). Genomic studies across hundreds of cancer cell lines have demonstrated that cancer cells containing KRAS mutations are highly dependent on KRAS function for cell growth and survival (McDonald, R. et al. Cell 170 (2017):577-592).The role of mutant KRAS as an oncogenic driver is further supported by extensive in vivo experimental evidence showing that mutant KRAS is required for the initiation and maintenance of initial tumors in animal models (Cox, AD et al. Nat Rev Drug Discov (2014) 13:828-51).
[0005] Taken together, these findings suggest that KRAS mutations play an important role in human cancer; therefore, the development of inhibitors targeting mutant KRAS may be useful in the clinical treatment of diseases characterized by KRAS mutations. Summary of the Invention

[0033] In one embodiment, the compound of formula I is 2-((2S,4S)-4-(7-(2-chloro-3-methylphenyl)-4-(3-(dimethylamino)-3-methylazetidin-1-yl)-6-fluoro-8-methyl-1H-imidazo[4,5-c]quinolin-1-yl)-1-((E)-4-fluorobut-2-enoyl)piperidin-2-yl)acetonitrile, 2-((2S,4S)-4-(7-(2-chloro-3-methylphenyl)-6-fluoro-8-methyl-4-((S)-1-((S)-1-methylpyrrolidin-2-yl)ethoxy)-1H-imidazo[4,5-c]quinolin-1-yl)-1-(2-fluoroacryloyl)piperidin-2-yl)acetonitrile, or a pharma- ceutical acceptable salt thereof is selected from.
[0034] It is further recognized that certain features of the invention that are described for clarity in the context of separate embodiments may also be provided in combination in a single embodiment (wherein the embodiments are intended to be combined as if described in multiple sub-formulas). Conversely, various features of the invention that are described for brevity in the context of a single embodiment may also be provided individually or in any suitable subcombination. Thus, it is contemplated that the features described as embodiments of compounds of formula I may be combined in any suitable combination.
[0035] The compounds described herein may be asymmetric (e.g., have one or more stereocenters). All stereoisomers, e.g., enantiomers and diastereomers, are intended unless otherwise indicated. Compounds of the present invention that contain asymmetrically substituted carbon atoms can be isolated in optically active or racemic forms. Methods for preparing optically active forms from optically inactive starting materials are known in the art, for example, by resolution of racemic mixtures or by stereoselective synthesis. Many geometric isomers of olefins, such as C=N double bonds, may also exist in the compounds described herein, and all such stable isomers are contemplated in the present invention. Cis and trans geometric isomers of the compounds of the present invention are described and can be isolated as a mixture of isomers or as separated isomeric forms.
[0036] The resolution of a racemic mixture of compounds can be carried out by any of many methods known in the art. One method is fractional recrystallization using a chiral resolving acid that is an optically active, salt-forming organic acid. Suitable resolving agents for fractional recrystallization are, for example, optically active acids, such as tartaric acid, diacetyltartaric acid, dibenzoyltartaric acid, mandelic acid, malic acid, lactic acid, or various optically active camphorsulfonic acids, such as the D and L forms of β-camphorsulfonic acid. Other suitable resolving agents for fractional crystallization include stereoisomerically pure forms of α-methyl-benzylamine (e.g., S and R forms, or diastereomerically pure forms), 2-phenylglycinol, norephedrine, ephedrine, N-methylephedrine, cyclohexylethylamine, 1,2-diaminocyclohexane, and the like.
[0037] Resolution of racemic mixtures may be accomplished by elution through a column packed with an optically active resolving agent (e.g., dinitrobenzoylphenylglycine). The composition of suitable elution solvents can be determined by one skilled in the art.
[0038] In some embodiments, the compounds of the invention have the (R) configuration. In other embodiments, the compounds have the (S) configuration. In compounds with more than one chiral center, each chiral center in the compound may be independently (R) or (S) unless otherwise indicated.
[0039] The compounds of the present invention also include tautomers. Tautomers result from the exchange of a single bond with an adjacent double bond along with the migration of a proton. Tautomers include prototropic tautomers, which are isomeric protonation states with the same empirical formula and total charge. Examples of prototropic tautomers include ketone-enol pairs, amide-imidic acid pairs, lactam-lactim pairs, enamine-imine pairs, and cyclic forms in which a proton can occupy more than one position in a heterocyclic ring system, such as 1H- and 3H-imidazole, 1H-, 2H- and 4H-1,2,4-triazole, 1H- and 2H-isoindole, and 1H- and 2H-pyrazole. Tautomers may be in equilibrium or sterically fixed in one form by appropriate substitution.
[0040] The compounds of the present invention may also include all isotopes of atoms occurring in intermediates or final compounds. Isotopes include atoms with the same atomic number but different mass numbers. For example, isotopes of hydrogen include tritium and deuterium. One or more constituent atoms of the compounds of the present invention may be replaced or substituted with an atomic isotope in natural or non-natural abundance ratio. In some embodiments, the compounds include at least one deuterium atom. For example, one or more hydrogen atoms in the compounds of the present disclosure may be replaced or substituted with deuterium. In some embodiments, the compounds include two or more deuterium atoms. In some embodiments, the compounds include 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 or 12 deuterium atoms. Synthetic methods for incorporating isotopes into organic compounds are known in the art (Deuterium Labeling in Organic Chemistry by Alan F. Thomas (New York, NY, Appleton-Century-Crofts, 1971; The Renaissance of H / D Exchange by Jens Atzrodt, Volker Derdau, Thorsten Fey and Jochen Zimmermann, Angew. Chem. Int. Ed. 2007, 7744-7765; The Organic Chemistry of Isotopic Labelling by James R. Hanson, Royal Society of Chemistry, 2011). Isotopically labeled compounds can be used in a variety of studies, e.g., NMR spectroscopy, metabolic experiments, and / or assays.
[0041] Substitution with heavier isotopes, such as deuterium, may confer certain therapeutic advantages due to superior metabolic stability, e.g., increased in vivo half-life or reduced dosage requirements, and therefore may be preferred in some circumstances (A. Kerekes et.al. J. Med. Chem. 2011, 54, 201-210; R. Xu et.al. J. Label Compd. Radiopharm. 2015, 58, 308-312).
[0042] The term "compound" as used herein is meant to include all stereoisomers, geometric isomers, tautomers, and isotopes of the structures depicted. The term is also meant to refer to the compounds of the invention regardless of how they are prepared, for example, synthetically, through a biological process (e.g., metabolic or enzymatic transformation), or a combination thereof.
[0043] All compounds and their pharma- ceutically acceptable salts can be found together with other substances, such as water and solvents (e.g., hydrates and solvates) or can be isolated. When in the solid state, the compounds described herein and their salts can occur in various forms, for example, in the form of solvates, including hydrates. Compounds may be in any solid state form, such as polymorphs or solvates, and therefore, unless otherwise specified, references herein to compounds and their salts should be understood to include any solid state form of the compound.
[0044] In some embodiments, the compound of the present invention or its salt is substantially isolated. "Substantially isolated" means that the compound is at least partially or substantially separated from the environment in which it was formed or detected. Partial separation may include, for example, a composition enriched in the compound of the present invention. Substantial separation may include a composition that includes at least about 50% by weight, at least about 60% by weight, at least about 70% by weight, at least about 80% by weight, at least about 90% by weight, at least about 95% by weight, at least about 97% by weight, or at least about 99% by weight of the compound of the present invention or its salt.
[0045] The phrase "pharmacologically acceptable" is used herein to refer to compounds, materials, compositions and / or dosage forms that are suitable, within the scope of sound medical judgment, for use in contact with the tissues of human beings and animals without undue toxicity, irritation, allergic response, or other problem or complication, commensurate with a reasonable benefit / risk ratio.
[0046] The expressions "ambient temperature" and "room temperature", as used herein, are understood in the art and generally refer to temperatures, e.g., reaction temperatures, which relate to the temperature of the room in which the reaction is carried out, e.g., a temperature of about 20° C. to about 30° C.
[0047] The present invention also includes pharma- ceutically acceptable salts of the compounds described herein. The term "pharma- ceutically acceptable salts" refers to derivatives of the disclosed compounds in which the parent compound is modified by converting an existing acid or base moiety into its salt form. Examples of pharma- ceutically acceptable salts include, but are not limited to, inorganic or organic acid salts of basic residues, such as amines; alkali or organic salts of acidic residues, such as carboxylic acids; and the like. The pharma- ceutical acceptable salts of the present invention include non-toxic salts of the parent compound formed, for example, from non-toxic inorganic or organic acids. The pharma- ceutical acceptable salts of the present invention may be synthesized from the parent compound containing a basic or acidic moiety by conventional chemical methods. In general, such salts can be prepared by reacting the free acid or base forms of these compounds with a stoichiometric amount of the appropriate base or acid in water or an organic solvent, or a mixture of the two; generally, non-aqueous media, such as ether, ethyl acetate, alcohols (e.g., methanol, ethanol, isopropanol, or butanol) or acetonitrile (MeCN) are preferred. A list of suitable salts can be found in Remington's Pharmaceutical Sciences 17 th Ed., (Mack Publishing Company, Easton, 1985), p. 1418, Berge et al., J. Pharm. Sci., 1977, 66(1), 1-19, and Stahl et al., Handbook of Pharmaceutical Salts: Properties, Selection, and Use, (Wiley, 2002). In some embodiments, the compounds described herein are in the N-oxide form.
[0048] synthesis The compounds of the invention, including their salts, may be prepared using known organic synthesis techniques and may be synthesised according to any of a number of possible synthetic routes, for example those in the following schemes.
[0049] The reaction for preparing the compounds of the present invention can be carried out in a suitable solvent, which can be easily selected by those skilled in the art of organic synthesis.A suitable solvent can be substantially non-reactive with the starting material (reactant), intermediate or product at the temperature at which the reaction is carried out, which can range, for example, from the freezing temperature of the solvent to the boiling temperature of the solvent.A given reaction can be carried out in one solvent or a mixture of more than one solvent.Depending on the specific reaction step, a suitable solvent for a specific reaction step can be selected by those skilled in the art.
[0050] Preparation of the compounds of the invention may involve the protection and deprotection of various chemical groups. The need for protection and deprotection, and the selection of appropriate protecting groups, can be readily determined by one of ordinary skill in the art. The chemistry of protecting groups can be found, for example, in Kocienski, Protecting Groups, (Thieme, 2007); Robertson, Protecting Group Chemistry, (Oxford University Press, 2000); Smith et al., March's Advanced Organic Chemistry: Reactions, Mechanisms, and Structure, 6 th Ed. (Wiley, 2007); Peturssion et al., “Protective Groups in Carbohydrate Chemistry,” J. Chem. Educ., 1997, 74(11), 1297; and Wuts et al., Protective Groups in Organic Synthesis, 4th Ed., (Wiley, 2006).
[0051] The reaction may be monitored according to any suitable method known in the art. For example, the formation of the product may be monitored by spectroscopic means, such as nuclear magnetic resonance spectroscopy (e.g., 1 H or 13C), infrared spectroscopy, spectrophotometry (eg, UV-visible), mass spectrometry, or by chromatographic methods such as high performance liquid chromatography (HPLC) or thin layer chromatography (TLC).
[0052] The following schemes provide general guidance relating to the preparation of compounds of the invention. Those skilled in the art will appreciate that the preparations shown in the schemes can be modified or optimized using general knowledge of organic chemistry to prepare various compounds of the invention.
[0053] [ka] Compounds of formula 1-18 can be prepared via the synthetic route outlined in Scheme 1. Starting material 1-1 can be halogenated with a suitable reagent (such as N-chloro-succinimide (NCS)) to give intermediate 1-2 (where Hal is a halide (such as F, Cl, Br, or I)). Compound 1-3 can be prepared by treating 1-2 with a reagent (such as triphosgene). Intermediate 1-3 can then be reacted with ester 1-4 to give nitro compound 1-5, which can be treated with a suitable reagent (e.g., POCl3) to give compound 1-6. S-coupling of intermediate 1-6 with amine 1-7 (where PG is a suitable protecting group (such as Boc)) can be performed. NAr reaction can be carried out to give compound 1-8. The nitro group in 1-8 can be reduced to NH2 in the presence of a reducing agent (e.g., Fe in acetic acid or sodium dithionite). Intermediate 1-9 can then be subjected to a cyclization reaction (e.g., using triethyl orthoformate) to give intermediate 1-10, followed by a SnAr reaction with sodium thiomethoxide to give 1-11. Cross-coupling reaction with 1-12 (M is a boronic acid, boronic ester, or appropriately substituted metal or metalloid [e.g., M is B(OR)2, Sn(alkyl)3, Zn-Hal, or CF3TMS]) under standard Suzuki cross-coupling conditions (e.g., in the presence of a palladium catalyst and a suitable base), or standard Stille cross-coupling conditions (e.g., in the presence of a palladium catalyst), or standard Negishi cross-coupling conditions (e.g., in the presence of a palladium catalyst), or trifluoromethylation conditions (e.g., in the presence of a copper catalyst) gives 1-13. Intermediate 1-15 can be prepared by cross-coupling reaction between 1-13 and an adduct of formula 1-14 (M is a boronic acid, a boronic ester, or an appropriately substituted metal [e.g., M is B(OR)2, Sn(alkyl)3, or Zn-Hal]) under standard Suzuki cross-coupling conditions (e.g., in the presence of a palladium catalyst and a suitable base), or standard Stille cross-coupling conditions (e.g., in the presence of a palladium catalyst), or standard Negishi cross-coupling conditions (e.g., in the presence of a palladium catalyst). Intermediate 1-15 can be converted to intermediate 1-16 via either oxidation of the sulfur group with a suitable oxidizing agent (e.g., m-CPBA) followed by a SnAr reaction, or a cross-coupling reaction (Org. Lett. 2002, 4, 979-981). Removal of the protecting group in 1-16 gives amine 1-17. Subsequent functionalization of the resulting amine, such as coupling with an acid chloride (e.g., acryloyl chloride), affords the desired products 1-18. The sequence of the above chemical reactions may be modified or omitted as necessary to suit the preparation of different analogs.
[0054] KRAS protein The Ras family consists of three members: KRAS, NRAS, and HRAS. RAS-mutated cancers account for approximately 25% of human cancers. KRAS is the most frequently mutated isoform in human cancers: 85% of all RAS mutations are in KRAS, 12% in NRAS, and 3% in HRAS (Simanshu, D. et al. Cell 170.1 (2017): 17-33). KRAS mutations are prevalent among the top three most lethal cancer types: pancreatic (97%), colorectal (44%), and lung (30%) (Cox, AD et al. Nat Rev Drug Discov (2014) 13: 828-51). The majority of RAS mutations occur at amino acid residues / codons 12, 13, and 61; mutations in codon 12 occur most frequently in KRAS. The frequency of certain mutations varies between RAS genes, with G12D mutations being the most prevalent in KRAS, while Q61R and G12R mutations occur most frequently in NRAS and HRAS. Furthermore, the spectrum of mutations in RAS isoforms differs between cancer types. For example, KRAS G12D mutations predominate in pancreatic cancer (51%), followed by colorectal adenocarcinoma (45%) and lung cancer (17%) (Cox, AD et al. Nat Rev Drug Discov (2014) 13:828-51). In contrast, KRAS G12C mutations predominate in non-small cell lung cancer (NSCLC) (where nearly half of mutant KRAS are G12C), accounting for 11-16% of lung adenocarcinomas and 2-5% of pancreatic and colorectal adenocarcinomas, respectively (Cox, AD et al. Nat. Rev. Drug Discov. (2014) 13:828-51a). Using shRNAs to knock down thousands of genes across hundreds of cancer cell lines, genomic studies have demonstrated that cancer cells exhibiting KRAS mutations are highly dependent on KRAS function to grow cells (McDonald, R. et al. Cell 170 (2017):577-592). Taken together, these findings suggest that KRAS mutations play a critical role in human cancers, and thus the development of inhibitors targeting mutant KRAS may be useful in the clinical treatment of diseases characterized by KRAS mutations.
[0055] How to use Cancer types involving KRAS, including G12C, G12V and G12D mutations, include, but are not limited to, adenocarcinomas (e.g., pancreatic, colorectal, lung, bladder, stomach, esophagus, breast, head and neck, neck skin, thyroid); hematopoietic malignancies (e.g., myeloproliferative neoplasms (MPN), myelodysplastic syndromes (MDS), chronic and juvenile myelomonocytic leukemia (CMML and JMML), acute myeloid leukemia (AML), acute lymphoblastic leukemia (ALL) and multiple myeloma (MM)); and other neoplasms (e.g., glioblastoma and sarcoma). Additionally, KRAS mutations have been associated with acquired resistance to anti-EGFR therapy (Knickelbein, K. et al. Genes & Cancer, (2015): 4-12). KRAS mutations have been found in immunological and inflammatory disorders (Fernandez-Medarde, A. et al. Genes & Cancer, (2011):344-358), such as Ras-associated lymphoproliferative disorder (RALD) or juvenile myelomonocytic leukemia (JMML), which are caused by somatic mutations in KRAS or NRAS.

[0174] In some embodiments, the composition is produced using a wet granulation process. In some embodiments, the composition is produced using a dry granulation process.
[0175] The compositions may be formulated in unit dosage form, each dosage containing from about 5 to about 1,000 mg (1 g), more usually from about 100 mg to about 500 mg, of the active ingredient. In some embodiments, each dosage contains about 10 mg of the active ingredient. In some embodiments, each dosage contains about 50 mg of the active ingredient. In some embodiments, each dosage contains about 25 mg of the active ingredient. The term "unit dosage form" refers to physically discrete units suitable as unitary dosages for human subjects and other mammals, each unit containing a predetermined quantity of active material calculated to produce the desired therapeutic effect in association with suitable pharmaceutical excipients.
[0176] The components used to formulate the pharmaceutical composition are of high purity and substantially free of potentially harmful contaminants (e.g., at least National Food grade, generally at least analytical grade, more typically at least pharmaceutical grade). Particularly for human consumption, the composition is preferably manufactured or formulated under Good Manufacturing Practice regulations as defined in applicable regulations of the U.S. Food and Drug Administration. For example, suitable formulations may be sterile and / or substantially isotonic, and / or in full compliance with all Good Manufacturing Practice regulations of the U.S. Food and Drug Administration.
[0177] The active compounds may be effective over a wide dosage range and are generally administered in a therapeutically effective amount. However, it will be understood that the amount of compound actually administered will usually be determined by the physician according to the appropriate circumstances, including the condition to be treated, the route of administration selected, the actual compound administered, the age, weight, and response of the individual patient, the severity of the patient's symptoms, and the like.
[0178] The therapeutic dosage of the compounds of the present invention may vary, for example, according to the particular use for which the treatment is made, the manner of administration of the compound, the health and condition of the patient, and the judgment of the prescribing physician. The proportion or concentration of the compounds of the present invention in a pharmaceutical composition may vary depending on a number of factors, including dosage, chemical characteristics (e.g., hydrophobicity), and route of administration. For example, the compounds of the present invention may be provided in an aqueous physiological buffer solution containing about 0.1 to about 10% w / v of the compound for parenteral administration. Some typical dosage ranges are about 1 μg / kg to about 1 g / kg of body weight per day. In some embodiments, the dosage range is about 0.01 mg / kg to about 100 mg / kg of body weight per day. The dosage is likely to depend on variables, such as the type and extent of progression of the disease or disorder, the overall health of the particular patient, the relative biological availability of the selected compound, the formulation of excipients, and its route of administration. Effective doses may be extrapolated from dose-response curves derived from in vitro or animal model test systems.
[0179] For the preparation of solid compositions, such as tablets, the main active ingredient is mixed with pharmaceutical excipients to form a solid preformulation composition containing a homogeneous mixture of the compound of the present invention.When these preformulation compositions are referred to as homogeneous, the active ingredient is typically uniformly distributed throughout the composition, so that the composition can be easily and uniformly subdivided into effective unit dosage forms, such as tablets, pills, and capsules.The solid preformulation is then subdivided into unit dosage forms of the above-mentioned type, such as about 0.1 to about 1000 mg of the active ingredient of the present invention.
[0180] The tablets or pills of the present invention may be coated or otherwise compounded to provide a dosage form that provides the advantage of prolonged action.For example, the tablet or pill may comprise an inner dosage and an outer dosage component, the latter being in the form of a coating over the former.The two components may be separated by an enteric layer that serves to resist disintegration in the stomach and allows the inner component to pass intact into the duodenum or be released in a delayed manner.A variety of materials may be used for such enteric layers or coatings, including a number of polymeric acids and mixtures of polymeric acids with materials such as shellac, cetyl alcohol and cellulose acetate.
[0181] Liquid forms into which the compounds and compositions of the present invention may be incorporated for administration orally or by injection include aqueous solutions, suitably flavored syrups, aqueous or oily suspensions, and emulsions flavored with edible oils, such as cottonseed oil, sesame oil, coconut oil, or peanut oil, as well as elixirs and similar pharmaceutical vehicles.
[0182] Compositions for inhalation or insufflation include solutions and suspensions in pharma- ceutically acceptable, aqueous or organic solvents or mixtures thereof, as well as powders. Liquid or solid compositions may contain suitable pharma- ceutically acceptable additives as described above. In some embodiments, the compositions are administered by oral or nasal respiratory routes for localized or systemic effect. Compositions may be nebulized by using inert gases. Nebulized solutions may be breathed directly from the nebulizing device, or the nebulizing device may be attached to a face mask, tent, or intermittent positive pressure breathing machine. Solution, suspension, or powder compositions may be administered orally or nasally from a device that delivers the formulation in an appropriate manner.
[0183] Topical formulations may include one or more conventional carriers. In some embodiments, ointments may include water and one or more hydrophobic carriers selected from, for example, liquid paraffin, polyoxyethylene alkyl ether, propylene glycol, white petrolatum, and the like. Cream carrier compositions may be based on water in combination with glycerol and one or more other components, for example, glycerol monostearate, PEG-glycerol monostearate, and cetylstearyl alcohol. Gels may be formulated using isopropyl alcohol and water in suitable combination with other components, for example, glycerol, hydroxyethylcellulose, and the like. In some embodiments, topical formulations include at least about 0.1, at least about 0.25, at least about 0.5, at least about 1, at least about 2, or at least about 5 wt% of the compound of the present invention. Topical formulations may be suitably packaged, for example, in 100 g tubes, optionally associated with instructions for use to treat a selected indication, for example, psoriasis or other skin conditions.
[0184] The amount of compound or composition administered to a patient will vary depending on what is being administered, the purpose of the administration, e.g., prophylaxis or therapy, the condition of the patient, the mode of administration, etc. In therapeutic applications, the composition may be administered to a patient already suffering from a disease in an amount sufficient to cure or at least partially arrest the symptoms of the disease and its complications. The effective dose will depend on the disease state being treated, and will be at the discretion of the attending clinician depending on factors such as the severity of the disease, the age, weight, and general condition of the patient, etc.
[0185] The compositions administered to a patient may be in the form of pharmaceutical compositions described above. These compositions may be sterilized by conventional aseptic techniques or sterile filtered. Aqueous solutions may be packaged or lyophilized for use as is, and lyophilized preparations are combined with a sterile aqueous carrier before administration. The pH of the compound preparations will typically be between 3 and 11, more preferably between 5 and 9, and most preferably between 7 and 8. It will be understood that certain use of the above-mentioned additives, carriers, or stabilizers will result in the formation of pharmaceutical salts.
[0186] The therapeutic dosage of the compounds of the present invention may vary, for example, according to the particular use for which the treatment is made, the manner of administration of the compound, the health and condition of the patient, and the judgment of the prescribing physician. The proportion or concentration of the compounds of the present invention in a pharmaceutical composition may vary depending on a number of factors, including dosage, chemical characteristics (e.g., hydrophobicity), and route of administration. For example, the compounds of the present invention may be provided in an aqueous physiological buffer solution containing about 0.1 to about 10% w / v of the compound for parenteral administration. Some typical dosage ranges are about 1 μg / kg to about 1 g / kg of body weight per day. In some embodiments, the dosage range is about 0.01 mg / kg to about 100 mg / kg of body weight per day. The dosage is likely to depend on variables, such as the type and extent of progression of the disease or disorder, the overall health of the particular patient, the relative biological availability of the selected compound, the formulation of excipients, and its route of administration. Effective doses may be extrapolated from dose-response curves derived from in vitro or animal model test systems.
[0187] Labeled Compounds and Assay Methods Another aspect of the present invention relates to the labeled (radiolabeled, fluorescently labeled, etc.) compounds of the present disclosure that will be useful in both in vitro and in vivo imaging techniques as well as assays for localizing and quantifying KRAS protein in tissue samples, including human, and for identifying KRAS ligands by inhibiting the binding of the labeled compounds. Substitution of one or more atoms of the compounds of the present disclosure may also be useful in generating special ADME (adsorption, distribution, metabolism, and excretion). Thus, the present invention includes KRAS binding assays that include such labeled or substituted compounds.
[0188] The present disclosure further includes isotopically labeled compounds of the present disclosure. An "isotopically" or "radiolabeled" compound is a compound of the present disclosure in which one or more atoms have been replaced or substituted by an atom having an atomic mass or mass number different from the atomic mass or mass number typically found in nature (i.e., naturally occurring). Suitable radionuclides that may be incorporated into the disclosed compounds include, but are not limited to, 2 H (also written as D for deuterium), 3 H (also written as T for tritium), 11 C. 13 C. 14 C. 13 N, 15 N, 15 O. 17 O. 18 O. 18 F, 35 S, 36 Cl, 82 Br, 75 Br, 76 Br, 77 Br, 123 I, 124 I, 125 I and 131 For example, one or more hydrogen atoms in the compounds of the present disclosure may be replaced by a deuterium atom (e.g., C of formula I, II, or any formula provided herein). 1~6One or more hydrogen atoms of an alkyl group may be optionally replaced with a deuterium atom, e.g., -CD3 is replaced with -CH3.) In some embodiments, an alkyl group of Formula I, II, or any formula provided herein may be perdeuterated.
[0189] One or more constituent atoms of the compounds presented herein may be replaced or substituted with an atomic isotope in natural or non-natural abundance ratio. In some embodiments, the compounds contain at least one deuterium atom. In some embodiments, the compounds contain two or more deuterium atoms. In some embodiments, the compounds contain 1-2, 1-3, 1-4, 1-5, or 1-6 deuterium atoms. In some embodiments, all of the hydrogen atoms in the compounds may be replaced or substituted with deuterium atoms.
[0190] Synthetic methods for incorporating isotopes into organic compounds are known in the art (Deuterium Labeling in Organic Chemistry by Alan F. Thomas (New York, NY, Appleton-Century-Crofts, 1971; The Renaissance of H / D Exchange by Jens Atzrodt, Volker Derdau, Thorsten Fey and Jochen Zimmermann, Angew. Chem. Int. Ed. 2007, 7744-7765; The Organic Chemistry of Isotopic Labelling by James R. Hanson, Royal Society of Chemistry, 2011). Isotopically labeled compounds may be used in a variety of studies, e.g., NMR spectroscopy, metabolic experiments, and / or assays.
[0191] Substitution with heavier isotopes, such as deuterium, may provide certain therapeutic advantages due to superior metabolic stability, such as increased in vivo half-life or reduced dosage requirements, and may therefore be preferred in some circumstances. (See, for example, A. Kerekes et.al. J. Med. Chem. 2011, 54, 201-210; R. Xu et.al. J. Label Compd. Radiopharm. 2015, 58, 308-312). In particular, substitution at one or more metabolic sites may provide one or more of the therapeutic advantages.
[0192] The radionuclide incorporated in the present radiolabeled compounds will depend on the particular application of that radiolabeled compound. For example, for in vitro adenosine receptor labeling and competition assays: 3 H, 14 C. 82 Br, 125 I, 131 I or 35 Compounds incorporating S may be useful. For radioimaging applications, 11 C. 18 F, 125 I, 123 I, 124 I, 131 I, 75 Br, 76 Br or 77 Br may be useful.
[0193] A "radiolabel" or "labeled compound" is understood to be a compound into which at least one radionuclide has been incorporated. In some embodiments, the radionuclide is 3 H, 14 C. 125 I, 35 S and 82 Br is selected.
[0194] The present disclosure may further include synthetic methods for incorporating radioisotopes into the compounds of the present disclosure. Synthetic methods for incorporating radioisotopes into organic compounds are well known in the art, and one of ordinary skill in the art would readily recognize methods applicable to the compounds of the present disclosure.
[0195] The labeled compounds of the present invention may be used in screening assays to identify and / or evaluate compounds. For example, a newly synthesized or identified labeled compound (i.e., test compound) can be evaluated for its ability to bind to KRAS protein by monitoring its concentration change when it is contacted with KRAS via tracking of the label. For example, a test compound (labeled) can be evaluated for its ability to reduce the binding of another compound (i.e., standard compound) that is known to bind to KRAS protein. Thus, the ability of the test compound to compete with the standard compound for direct binding to KRAS protein correlates with its binding affinity. Conversely, in some other screening assays, the standard compound is labeled and the test compound is not labeled. Thus, the concentration of the labeled standard compound is monitored to evaluate the competition between the standard compound and the test compound, thereby ascertaining the relative binding affinity of the test compound.
[0196] kit The present disclosure also includes pharmaceutical kits useful in treating or preventing diseases or disorders associated with the activity of KRAS, such as cancer or infectious diseases, which include one or more containers containing a pharmaceutical composition comprising a therapeutically effective amount of a compound of formula I, II, or any of these embodiments. Such kits may further include one or more of various conventional pharmaceutical kit components, such as a container containing one or more pharma- ceutically acceptable carriers, additional containers, etc., as would be readily apparent to one skilled in the art. Instructions, either as an insert or label indicating the amount of components to be administered, guidelines for administration, and / or guidelines for mixing components may also be included in the kit.
[0197] The present invention will be described in more detail by specific examples.The following examples are provided for illustrative purposes and are not intended to limit the invention in any way.Those skilled in the art will easily recognize various non-critical parameters that can be changed or modified to obtain substantially the same results.The compound of the example is found to inhibit the activity of KRAS according to at least one assay described herein.

[0392] Example A. GDP-GTP Exchange Assay. Inhibitor potency of the exemplified compounds was determined by a fluorescence-based guanine nucleotide exchange assay, which measures the exchange of Bodipy-GDP (fluorescently labeled GDP) for GppNHp (non-hydrolyzable GTP analog) to generate an active state of KRAS in the presence of SOS1 (a guanine nucleotide exchange factor). Inhibitors were serially diluted in DMSO and a volume of 0.1 μL was transferred to wells of a black low volume 384-well plate. A volume of 5 μL / well of Bodipy-loaded KRAS G12C diluted to 5 nM in assay buffer (25 mM Hepes pH 7.5, 50 mM NaCl, 10 mM MgCl2 and 0.01% Brij-35) was added to the plate and pre-incubated with the inhibitor for 2 hours at ambient temperature. Appropriate controls (enzyme without inhibitor or with G12C inhibitor (AMG-510)) were included on the plate. Exchange was initiated by the addition of a volume of 5 μL / well containing 1 mM GppNHp and 300 nM SOS1 in assay buffer. The 10 μL / well reaction concentrations of bodipy-loaded KRAS G12C, GppNHp, and SOS1 were 2.5 nM, 500 uM, and 150 nM, respectively. The reaction plate was incubated at ambient temperature for 2 hours, the time during which GDP-GTP exchange is expected to be complete in the absence of inhibitors. For KRAS G12D and G12V mutants, a similar guanine nucleotide exchange assay was used, with a final concentration of 2.5 nM for the bodipy-loaded KRAS protein and 4 and 3 hours of incubation after addition of the GppNHp-SOS1 mixture for G12D and G12V, respectively. A cyclic peptide described to selectively bind to the G12D mutant (Sakamoto et al., BBRC 484.3 (2017), 605-611) or an internal compound with confirmed binding was used as a positive control in the assay plate. Fluorescence intensity was measured with a PheraStar plate reader instrument (BMG Labtech) with excitation at 485 nm and emission at 520 nm.

[0404] Example H: Caco2 Assay Caco-2 cells were grown at 37°C in a 5% CO2 atmosphere in DMEM growth medium supplemented with 10% (v / v) fetal bovine serum, 1% (v / v) non-essential amino acids, penicillin (100 U / mL), and streptomycin (100 μg / mL). Confluent cell monolayers of Caco-2 were subcultured every 7 or 4 days by treatment with 0.05% trypsin containing 1 μM EDTA. Caco-2 cells were seeded in 96-well Transwell plates. The seeding density of Caco-2 cells was 14,000 cells / well. After seeding, the DMEM growth medium was replaced every other day. For Caco-2 cells, cell monolayers were used for transport assays on days 22–25.
[0405] The cell culture medium was removed and replaced with HBSS. To measure TEER, HBSS was added to the donor compartment (apical) and receiver compartment (basolateral). TEER was measured by using a REMS autosampler to ensure the integrity of the cell monolayer. TEER values ≥ 300 Ω cm 2 Caco-2 cell monolayers with 100 μg / cm2 were used for transport experiments. app To determine the β-acetylglucosamine (β-glucosamine), a solution of the test compound in HBSS (50 μM) was added to the donor compartment (apical side) and a solution of 4% BSA in HBSS was added to the receiver compartment (basolateral). The apical volume was 0.075 mL and the basolateral volume was 0.25 mL. The incubation time was 120 min at 37° C. in a 5% CO2 atmosphere. At the end of the incubation time, samples were collected from the donor and receiver sides and proteins were precipitated by adding an equal volume of acetonitrile. After centrifugation (3000 rpm, Allegra X-14R Centrifuge supplied by Beckman Coulter, Indianapolis, IN), the supernatant was collected for LCMS analysis. The formula: P app (cm / s)=(F * VD) / (SA * MD) The permeation value was determined according to the following formula: where the flux rate (F, amount / time) was calculated from the slope of the cumulative amount of the target compound on the receiver side, SA is the surface area of the cell membrane, VD is the donor volume, and MD is the initial amount of solution in the donor chamber.

[0408] Example I: Human Whole Blood Stability Whole blood stability of example compounds was determined by LC-MS / MS. A 96-well Flexi-Tier™ Block (Analytical Sales & Services, Inc, Flanders, NJ) was used as an incubation plate containing 1.0 mL glass vials with 0.5 mL of blood (gender-mixed human whole blood sourced from BIOIVT, Hicksville, NY or similar source) per vial. Blood was pre-warmed to 37° C. in a water bath for 30 minutes. 96-deep-well analytical plates were prepared by adding 100 μL ultrapure water / well. 50 μL chilled ultrapure water / well was added to a 96-deep-well sample collection plate and covered with a sealing mat. 1 μL of 0.5 mM compound working solution (DMSO:water) was added to the blood in the incubation plate to a final concentration of 1 μM, mixed thoroughly by pipetting, and 50 μL was transferred to the T=0 well of the sample collection plate. After the blood is held in water for 2 minutes, 400 μL stop solution / well (acetonitrile with internal standard) is added. The incubation plate is placed in a 37°C Incu-Shaker CO2 Mini incubator (Benchmark Scientific, Sayreville, NJ) and shaken at 150 rpm. At 1, 2, and 4 hours, the blood samples are thoroughly mixed by pipetting and 50 μL is transferred to the corresponding wells of the sample collection plate. After the blood is held in water for 2 minutes, 400 μL stop solution / well is added. The collection plate is sealed and vortexed at 1700 rpm for 3 minutes (VX-2500 Multi-Tube Vortexer, VWR International, Radnor, PA), and the samples are centrifuged in the collection plate at 3500 rpm for 10 minutes (Allegra X-14R Centrifuge Beckman Coulter, Indianapolis, IN). Transfer 100 μL supernatant / well from the sample collection plate to the corresponding wells of the analysis plate. Vortex the final plate at 1700 rpm for 1 minute and analyze the samples by LC-MS / MS. The peak area ratios of the 1, 2, and 4 hour samples relative to T=0 are used to determine percent remaining.The natural logarithm of percent remaining versus time was used to determine the slope to calculate the compound half-life in blood (t 1 / 2 Calculate the slope (=0.693 / slope).
[0409] Human whole blood stability data is provided below in Table 5. The symbol "†" indicates WBS ≦70%, "††" indicates WBS >70% but ≦90%, and "†††" indicates WBS >90%. "NA" indicates no WBS data is available. [Table 5]
[0410] Example J: In Vitro Intrinsic Clearance Protocol For in vitro metabolic stability experiments, test compounds are incubated with human liver microsomes at 37°C. The incubation mixture contains test compound (1 μM), NADPH (2 mM), and human liver microsomes (0.5 mg protein / mL) in 100 mM phosphate buffer (pH 7.4). The mixture is pre-incubated at 37°C for 2 min before adding NADPH. The reaction is started upon addition of NADPH and quenched with ice-cold methanol at 0, 10, 20, and 30 min. The stopped incubation mixture is analyzed using an LC-MS / MS system. The analysis system consists of a Shimadzu LC-30AD binary pump system and a SIL-30AC autosampler (Shimadzu Scientific Instruments, Columbia, MD) coupled with a Sciex Triple Quad 6500+ mass spectrometer supplied by Applied Biosystems (Foster City, CA). Chromatographic separation of test compounds and internal standards is achieved using a Hypersil Gold C18 column (50×2.1 mm, 5 μM, 175 Å) supplied by ThermoFisher Scientific (Waltham, MA). Mobile phase A consists of 0.1% formic acid in water and mobile phase B consists of 0.1% formic acid in acetonitrile. The total run time of LC-MS / MS can be 2.75 min at a flow rate of 0.75 mL / min. Peak area integration and peak area ratio calculations are performed using Analyst software (version 1.6.3) supplied by Applied Biosystems.
[0411] In vitro intrinsic clearance (CL int,インビトロ ) is the t 1 / 2 From CL int,インビトロ =(0.693 / t 1 / 2 )×(1 / C タンパク質 ) where C タンパク質 is the protein concentration in the incubation, and t 1 / 2 is determined by the slope (k) of the log-linear regression analysis of the concentration versus time profile (hence, t1 / 2 Using physiologically based adjustment factors, liver microsomal protein concentration (45 mg protein / g liver), and liver weight (21 g / kg body weight), CL int,インビトロ Values are scaled to in vivo values for humans. CL int =CL int,インビトロ The formula is then used: × (mg protein / g liver weight) × (g liver weight / kg body weight). CL is then calculated in a well-mixed liver model that ignores all binding. int and hepatic blood flow Q (20 mL min in humans) -1 ·kg -1 ) to measure in vivo hepatic clearance (CL H ) to CL H =(Q × CL int ) / (Q+CL int ) CL divided by Q H The hepatic extraction rate was calculated as:
[0412] Example K: In vivo Pharmacokinetic Protocol For in vivo pharmacokinetic studies, test compounds are administered intravenously or by oral gavage to male Sprague-Dawley rats or male and female cynomolgus monkeys. For intravenous (IV) administration, test compounds are administered at 0.5-1 mg / kg via IV bolus for rats and via 5- or 10-min IV infusion for monkeys using a formulation of dimethylacetamide (DMAC) 10% in acidified saline. For oral (PO) administration, test compounds are administered at 1.0-3.0 mg / kg using methylcellulose 0.5% in citrate buffer (pH 2.5) containing 5% DMAC. Blood samples are collected pre-dose and at various time points up to 24 hours after dosing. All blood samples are collected using EDTA as an anticoagulant and centrifuged to obtain plasma samples. Plasma concentrations of test compounds are determined by LC-MS methods. Measured plasma concentrations are used to calculate PK parameters by standard non-compartmental methods using the Phoenix® WinNonlin software program (version 8.0, Pharsight Corporation).
[0413] Cassette dosing of test compounds is performed in rats and monkeys to obtain preliminary PK parameters.
[0414] In vivo pharmacokinetic studies using male beagle dogs may be carried out under the above conditions.
[0415] Example L: Time-Dependent Inhibition (TDI) Protocol for CYPs This assay is designed to characterize the increase in CYP inhibition associated with metabolism of the test compound over time. Potential mechanisms for this include the formation of tightly bound and quasi-irreversible inhibitory metabolite complexes or inactivation of P450 enzymes by covalent adduct formation of metabolites. Because 10-fold dilutions are used in this experiment to reduce metabolite concentrations, the effect of reversible inhibition is reduced, but it is possible (although not common) to obtain a positive result if the metabolite is a very potent CYP inhibitor.
[0416] Results are obtained using human liver microsomes (HLM) with a cocktail of CYP-specific probe substrates at 4x their Km concentrations for CYP2C9, 2C19, 2D6, and 3A4 (midazolam). HLM can be preincubated with test compounds at a concentration of 10 μM for 30 min in the presence (+N) or absence (-N) of an NADPH regenerating system, diluted 10-fold, and a new aliquot of NADPH regenerating system added and incubated for 8 min in the presence of the substrate cocktail. Using a calibration curve of metabolite standards, enzyme activity can be quantitatively measured using LC-MS / MS. Additionally, incubations containing known time-dependent inhibitors (thienilic acid (CYP2C9), ticlopidine (CYP2C19), paroxetine (CYP2D6), and troleandomycin (CYP3A4)) used as positive controls are preincubated for 30 min in the presence or absence of an NADPH regenerating system.
[0417] The analytical system consists of a Shimadzu LC-30AD binary pump system and a SIL-30AC autosampler (Shimadzu Scientific Instruments, Columbia, MD) coupled with a Sciex Triple Quad 6500+ mass spectrometer supplied by Applied Biosystems (Foster City, CA). Chromatographic separation of analytes and internal standards can be achieved using an ACQUITY UPLC BEH 130A, 2.1×50 mm, 1.7 μm HPLC column (Waters Corp, Milford, MA). Mobile phase A consists of water with 0.1% formic acid, and mobile phase B consists of acetonitrile with 0.1% formic acid. The total LC-MS / MS run time is 2.50 min at a flow rate of 0.9 mL / min. Peak area integration and peak area ratio calculations are performed using Analyst software (version 1.6.3) supplied by Applied Biosystems.
[0418] The percent of control CYP2C9, CYP2C19, CYP2D6, and CYP3A4 activity remaining after preincubation of compound with NADPH is calculated after correcting for the corresponding control vehicle activity, with 0 minutes set to 100%. A linear regression plot of the natural logarithm of % activity remaining versus time for each isoenzyme is used to calculate the slope. This slope represents the rate of enzyme decline, i.e., K obs is equivalent to.
