Definitions

  • Ras represents a group of closely related monomeric globular proteins of 189 amino acids (21 kDa molecular mass) which are associated with the plasma membrane and which bind either GDP or GTP. Ras acts as a molecular switch. When Ras contains bound GDP it is in the resting or off position and is "inactive". In response to exposure of the cell to certain growth promoting stimuli, Ras is induced to exchange its bound GDP for a GTP. With GTP bound, Ras is
  • Ras protein itself has a very low intrinsic ability to hydro lyze GTP back to GDP, thus turning itself into the off state. Switching Ras off requires extrinsic proteins termed GTPase- activating proteins (GAPs) that interact with Ras and greatly accelerate the conversion of GTP to GDP. Any mutation in Ras which affects its ability to interact with GAP or to convert GTP back to GDP will result in a prolonged activation of the protein and consequently a prolonged signal to the cell telling it to continue to grow and divide. Because these signals result in cell growth and division, overactive Ras signaling may ultimately lead to cancer.
  • GAPs GTPase- activating proteins
  • Ras proteins contain a G domain which is responsible for the enzymatic activity of Ras (e.g., guanine nucleotide binding and hydrolysis (GTPase reaction)). It also contains a C-terminal extension, known as the CAAX box, which may be post-translationally modified and is responsible for targeting the protein to the membrane.
  • the G domain is approximately 21-25 kDa in size and contains a phosphate binding loop (P-loop).
  • the P-loop represents the pocket where the nucleotides are bound in the protein; this is the rigid part of the domain with conserved amino acid residues which are essential for nucleotide binding and hydrolysis (Glycine 12, Threonine 26 and Lysine 16).
  • the G domain also contains the so called Switch I (residues 30-40) and Switch II (residues 60-76) regions, both of which are the dynamic parts of the protein which are often represented as the "spring-loaded” mechanism because of their ability to switch between the resting and loaded state.
  • Threonine-35 and glycine-60 form key hydrogen bonds with the ⁇ -phosphate of GTP, which maintain Switch I and Switch II regions, respectively, in their active conformation. After hydrolysis of GTP and release of phosphate, the regions relax into the inactive GDP conformation.
  • the most notable members of the Ras subfamily are HRAS, KRAS and NRAS, mainly for being implicated in many types of cancer.
  • G12C is a frequent mutation of K-Ras gene (glycine- 12 to cysteine). This mutation has been found in about 13% of cancer occurrences, including about 43% of lung cancer occurrences and almost 100% of MYH-associates polyposis (familial colon cancer syndrome). However targeting this gene with small molecules is a challenge.

  • atropisomer s refers to conformational stereoisomers which occur when rotation about a single bond in the molecule is prevented, or greatly slowed, as a result of steric interactions with other parts of the molecule and the substituents at both ends of the single bond are asymmetrical (i.e., optical activity arises without requiring an asymmetric carbon center or stereocenter). Where the rotational barrier about the single bond is high enough, and interconversion between conformations is slow enough, separation and isolation of the isomeric species may be permitted.
  • Atropisomers are enantiomers (or epimers) without a single asymmetric atom.
  • Atropisomerism is defined to exist where the isomers have a half-life (ti /2 ) of at least 1000 seconds, which is a free energy barrier of 22.3 kcal mol “1 (93.3 kJ mol "1 ) at 300 K (Oki, M., "Recent Advances in Atropisomerism," Topics in Stereochemistry (1983) 14: 1).

  • the energy barrier to thermal racemization of atropisomers may be determined by the steric hindrance to free rotation of one or more bonds forming a chiral axis. Certain biaryl compounds exhibit atropisomerism where rotation around an interannular bond lacking C2 symmetry is restricted.
  • the free energy barrier for isomerization (enantiomerization) is a measure of the stability of the interannular bond with respect to rotation. Optical and thermal excitation can promote racemization of such isomers, dependent on electronic and steric factors.

Abstract

The present disclosure provides inhibitors of Ras protein. Also disclosed are methods to modulate the activity of Ras protein and methods of treatment of disorders mediated by Ras protein.

Description

SUBSTITUTED QUINAZOLINE COMPOUNDS AND METHODS OF USE
CROSS REFERENCE TO RELATED APPLICATIONS
[0001] This application claims the benefit of U.S. Provisional Application No. 62/315,532, filed on March 30, 2016, and U.S. Provisional Application No. 62/404,539, filed on October 5, 2016, each incorporated herein by reference in its entirety.
BACKGROUND
[0002] Ras represents a group of closely related monomeric globular proteins of 189 amino acids (21 kDa molecular mass) which are associated with the plasma membrane and which bind either GDP or GTP. Ras acts as a molecular switch. When Ras contains bound GDP it is in the resting or off position and is "inactive". In response to exposure of the cell to certain growth promoting stimuli, Ras is induced to exchange its bound GDP for a GTP. With GTP bound, Ras is
"switched on" and is able to interact with and activate other proteins (its "downstream targets"). The Ras protein itself has a very low intrinsic ability to hydro lyze GTP back to GDP, thus turning itself into the off state. Switching Ras off requires extrinsic proteins termed GTPase- activating proteins (GAPs) that interact with Ras and greatly accelerate the conversion of GTP to GDP. Any mutation in Ras which affects its ability to interact with GAP or to convert GTP back to GDP will result in a prolonged activation of the protein and consequently a prolonged signal to the cell telling it to continue to grow and divide. Because these signals result in cell growth and division, overactive Ras signaling may ultimately lead to cancer.
[0003] Structurally, Ras proteins contain a G domain which is responsible for the enzymatic activity of Ras (e.g., guanine nucleotide binding and hydrolysis (GTPase reaction)). It also contains a C-terminal extension, known as the CAAX box, which may be post-translationally modified and is responsible for targeting the protein to the membrane. The G domain is approximately 21-25 kDa in size and contains a phosphate binding loop (P-loop). The P-loop represents the pocket where the nucleotides are bound in the protein; this is the rigid part of the domain with conserved amino acid residues which are essential for nucleotide binding and hydrolysis (Glycine 12, Threonine 26 and Lysine 16). The G domain also contains the so called Switch I (residues 30-40) and Switch II (residues 60-76) regions, both of which are the dynamic parts of the protein which are often represented as the "spring-loaded" mechanism because of their ability to switch between the resting and loaded state. Threonine-35 and glycine-60 form key hydrogen bonds with the γ-phosphate of GTP, which maintain Switch I and Switch II regions, respectively, in their active conformation. After hydrolysis of GTP and release of phosphate, the regions relax into the inactive GDP conformation.
[0004] The most notable members of the Ras subfamily are HRAS, KRAS and NRAS, mainly for being implicated in many types of cancer. However, there are many other members including DIRAS 1 ; DIRAS2; DIRAS3; ERAS; GEM; MRAS; NKIRAS 1 ; NKIRAS2; NRAS; RALA; RALB; RAP1A; RAP1B; RAP2A; RAP2B; RAP2C; RASD1 ; RASD2; RASL10A; RASL10B; RASL11A; RASL11B; RASL12; REM1 ; REM2; RERG; RERGL; RRAD; RRAS; and RRAS2.
[0005] Mutations in any one of the three main isoforms of RAS (H-Ras, N-Ras, or K-Ras) genes are among the most common events in human tumorigenesis. About 30% of all human tumors are found to carry some mutation in Ras genes. Remarkably, K-Ras mutations are detected in 25- 30% of tumors. By comparison, the rates of oncogenic mutation occurring in the N-Ras and H- Ras family members are much lower (8% and 3%, respectively). The most common K-Ras mutations are found at residue G12 and G13 in the P-loop and at residue Q61.
[0006] G12C is a frequent mutation of K-Ras gene (glycine- 12 to cysteine). This mutation has been found in about 13% of cancer occurrences, including about 43% of lung cancer occurrences and almost 100% of MYH-associates polyposis (familial colon cancer syndrome). However targeting this gene with small molecules is a challenge.
SUMMARY OF THE INVENTION
[0007] In view of the foregoing, there is a need in the art for small molecules that target Ras (e.g., K-Ras, H-Ras and/or N-Ras) and for use of such compounds in the treatment of various diseases, such as cancer. The present disclosure provides these and other related advantages.

[0048] The term "substituted" refers to moieties having substituents replacing a hydrogen on one or more carbons or heteroatoms of the structure. It will be understood that "substitution" or "substituted with" includes the implicit proviso that such substitution is in accordance with permitted valence of the substituted atom and the substituent, and that the substitution results in a stable compound, e.g., which does not spontaneously undergo transformation such as by rearrangement, cyclization, elimination, etc. As used herein, the term "substituted" is
contemplated to include all permissible substituents of organic compounds. In a broad aspect, the permissible substituents include acyclic and cyclic, branched and unbranched, carbocyclic and heterocyclic, aromatic and non-aromatic substituents of organic compounds. The permissible substituents can be one or more and the same or different for appropriate organic compounds. For purposes of this disclosure, the heteroatoms such as nitrogen may have hydrogen
substituents and/or any permissible substituents of organic compounds described herein which satisfy the valences of the heteroatoms. Substituents can include any substituents described herein, for example, a halogen, a hydroxyl, a carbonyl (such as a carboxyl, an alkoxycarbonyl, a formyl, or an acyl), a thiocarbonyl (such as a thioester, a thioacetate, or a thioformate), an alkoxyl, a phosphoryl, a phosphate, a phosphonate, a phosphinate, an amino, an amido, an amidine, an imine, a cyano, a nitro, an azido, a sulfhydryl, an alkylthio, a sulfate, a sulfonate, a sulfamoyl, a sulfonamido, a sulfonyl, a heterocyclyl, an aralkyl, a carbocycle, a heterocycle, a cycloalkyl, a heterocycloalkyl, an aromatic and heteroaromatic moiety.

[0049] It will be understood by those skilled in the art that substituents can themselves be substituted, if appropriate. Unless specifically stated as "unsubstituted," references to chemical moieties herein are understood to include substituted variants. For example, reference to a "heteroaryl" group or moiety implicitly includes both substituted and unsubstituted variants.
[0050] Where substituent groups are specified by their conventional chemical formulae, written from left to right, they equally encompass the chemically identical substituents that would result from writing the structure from right to left, e.g., -CH20- is equivalent to -OCH2-.
[0051] "Optional" or "optionally" means that the subsequently described event of circumstances may or may not occur, and that the description includes instances where the event or
circumstance occurs and instances in which it does not. For example, "optionally substituted aryl" means that the aryl group may or may not be substituted and that the description includes both substituted aryl groups and aryl groups having no substitution.
[0052] "Electrophile" or "electrophilic moiety" is any moiety capable of reacting with a nucleophile (e.g., a moiety having a lone pair of electrons, a negative charge, a partial negative charge and/or an excess of electrons, for example an -SH group). Electrophiles typically are electron poor or comprise atoms which are electron poor. In certain embodiments, an
electrophile contains a positive charge or partial positive charge, has a resonance structure which contains a positive charge or partial positive charge, or is a moiety in which derealization or polarization of electrons results in one or more atoms which contains a positive charge or partial positive charge. In some embodiments, an electrophile comprises a conjugated double bond, for example an α,β-unsaturated carbonyl or α,β-unsaturated thiocarbonyl compound.
[0053] A "polar group" refers to a moiety with one or more dipoles as a result of opposing charges from one or more polar bonds arranged asymmetrically. A polar bond is any covalent bond between atoms of non- identical electronegativity. A polar group can be a group that is more hydrophilic than an alkyl group. In some embodiments, a polar group is a metal chelator or a metal chelator moiety. In some embodiments, a polar gorup comprises at least one heteroatom selected from S, O, and N. For example, a polar group can be an alkyl group that is substituted with one or more functional groups comprising a heteroatom. For example, a polar group can be an alkyl group substituted with one or more alcohol, ether, amine, hydroxyamine, aldehyde, ketone, ester, carboxylic acid, thiol, thioether, thiocarbonyl, sulfonate, sulfunite, phosphonate ester, amide, heterocycle and/or oxime.
[0054] The term "metal chelator" or "metal chelator moiety" is any moiety capable of forming two or more separate coordinate bonds between the metal chelator group and a single central metal atom or metal ion. Metal chelators typically have at least one pair of unbonded electrons which can bind to a metal atom or metal ion. In certain embodiments, a metal chelator moiety comprises at least two heteroatoms selected from S, O, and N. In some embodiments, the metal chelator moiety is a bidentate or tridenate functional group. In some embodiments, a metal chelator moiety comprises a bidentate functional group selected from the group consisting of hydroxyamine, hydroxyamide, sulfonamide, urea, amide and oxime. In some embodiments, a metal chelator moiety comprises two or more monodentate functional groups selected from the group consisting of hydroxy, amino, ether, aldehyde, ketone, amide, thiol, thioether, heterocycle (e.g. imidazole) or oxime.
[0055] Compounds of the present disclosure also include crystalline and amorphous forms of those compounds, pharmaceutically acceptable salts, and active metabolites of these compounds having the same type of activity, including, for example, polymorphs, pseudopolymorphs, solvates, hydrates, unsolvated polymorphs (including anhydrates), conformational polymorphs, and amorphous forms of the compounds, as well as mixtures thereof.
[0056] The compounds described herein may exhibit their natural isotopic abundance, or one or more of the atoms may be artificially enriched in a particular isotope having the same atomic number, but an atomic mass or mass number different from the atomic mass or mass number predominantly found in nature. All isotopic variations of the compounds of the present disclosure, whether radioactive or not, are encompassed within the scope of the present disclosure. For example, hydrogen has three naturally occurring isotopes, denoted 1H (protium),
2 H (deuterium), and 3 H (tritium). Protium is the most abundant isotope of hydrogen in nature. Enriching for deuterium may afford certain therapeutic advantages, such as increased in vivo half-life and/or exposure, or may provide a compound useful for investigating in vivo routes of drug elimination and metabolism. Isotopically-enriched compounds may be prepared by conventional techniques well known to those skilled in the art.
[0057] "Isomers" are different compounds that have the same molecular formula.
"Stereoisomers" are isomers that differ only in the way the atoms are arranged in space.
"Enantiomers" are a pair of stereoisomers that are non superimpo sable mirror images of each other. A 1: 1 mixture of a pair of enantiomers is a "racemic" mixture. The term "(±)" is used to designate a racemic mixture where appropriate. "Diastereoisomers" or "diastereomers" are stereoisomers that have at least two asymmetric atoms but are not mirror images of each other. The absolute stereochemistry is specified according to the Cahn-Ingold-Prelog R-S system. When a compound is a pure enantiomer, the stereochemistry at each chiral carbon can be specified by either R or S. Resolved compounds whose absolute configuration is unknown can be designated (+) or (-) depending on the direction (dextro- or levorotatory) in which they rotate plane polarized light at the wavelength of the sodium D line. Certain compounds described herein contain one or more asymmetric centers and can thus give rise to enantiomers, diastereomers, and other stereoisomeric forms, the asymmetric centers of which can be defined, in terms of absolute stereochemistry, as (R)- or (S)-. The present chemical entities,
pharmaceutical compositions and methods are meant to include all such possible stereoisomers, including racemic mixtures, optically pure forms, mixtures of diastereomers and intermediate mixtures. Optically active (R)- and (S)-isomers can be prepared using chiral synthons or chiral reagents, or resolved using conventional techniques. The optical activity of a compound can be analyzed via any suitable method, including but not limited to chiral chromatography and polarimetry, and the degree of predominance of one stereoisomer over the other isomer can be determined.
[0058] Chemical entities having carbon-carbon double bonds or carbon-nitrogen double bonds may exist in Z- or E- form (or cis- or trans- form). Furthermore, some chemical entities may exist in various tautomeric forms. Unless otherwise specified, chemical entities described herein are intended to include all Z-, E- and tautomeric forms as well.
[0059] The term "salt" or "pharmaceutically acceptable salt" refers to salts derived from a variety of organic and inorganic counter ions well known in the art. Pharmaceutically acceptable acid addition salts can be formed with inorganic acids and organic acids. Inorganic acids from which salts can be derived include, for example, hydrochloric acid, hydrobromic acid, sulfuric acid, nitric acid, phosphoric acid, and the like. Organic acids from which salts can be derived include, for example, acetic acid, propionic acid, glycolic acid, pyruvic acid, oxalic acid, maleic acid, malonic acid, succinic acid, fumaric acid, tartaric acid, citric acid, benzoic acid, cinnamic acid, mandelic acid, methanesulfonic acid, ethanesulfonic acid, p-toluenesulfonic acid, salicylic acid, and the like. Pharmaceutically acceptable base addition salts can be formed with inorganic and organic bases. Inorganic bases from which salts can be derived include, for example, sodium, potassium, lithium, ammonium, calcium, magnesium, iron, zinc, copper, manganese, aluminum, and the like. Organic bases from which salts can be derived include, for example, primary, secondary, and tertiary amines, substituted amines including naturally occurring substituted amines, cyclic amines, basic ion exchange resins, and the like, specifically such as isopropylamine, trimethylamine, diethylamine, triethylamine, tripropylamine, and ethanolamine. In some embodiments, the pharmaceutically acceptable base addition salt is chosen from ammonium, potassium, sodium, calcium, and magnesium salts.
[0060] "Pharmaceutically acceptable carrier, diluent or excipient" includes without limitation any adjuvant, carrier, excipient, glidant, sweetening agent, diluent, preservative, dye, colorant, flavor enhancer, surfactant, wetting agent, dispersing agent, suspending agent, stabilizer, isotonic agent, solvent, or emulsifier which has been approved by the United States Food and Drug Administration as being acceptable for use in humans or domestic animals.
[0061] The term "effective amount" or "therapeutically effective amount" refers to that amount of a compound described herein that is sufficient to affect the intended application, including but not limited to disease treatment, as defined below. The therapeutically effective amount may vary depending upon the intended treatment application (in vivo), or the subject and disease condition being treated, e.g., the weight and age of the subject, the severity of the disease condition, the manner of administration and the like, which can readily be determined by one of ordinary skill in the art. The term also applies to a dose that will induce a particular response in target cells, e.g., reduction of platelet adhesion and/or cell migration. The specific dose will vary depending on the particular compounds chosen, the dosing regimen to be followed, whether it is administered in combination with other compounds, timing of administration, the tissue to which it is administered, and the physical delivery system in which it is carried.
[0062] As used herein, "treatment" or "treating" refers to an approach for obtaining beneficial or desired results with respect to a disease, disorder, or medical condition including but not limited to a therapeutic benefit and/or a prophylactic benefit. By therapeutic benefit is meant eradication or amelioration of the underlying disorder being treated. Also, a therapeutic benefit is achieved with the eradication or amelioration of one or more of the physiological symptoms associated with the underlying disorder such that an improvement is observed in the subject,
notwithstanding that the subject may still be afflicted with the underlying disorder. In certain embodiments, for prophylactic benefit, the compositions are administered to a subject at risk of developing a particular disease, or to a subject reporting one or more of the physiological symptoms of a disease, even though a diagnosis of this disease may not have been made.
[0063] A "therapeutic effect," as that term is used herein, encompasses a therapeutic benefit and/or a prophylactic benefit as described above. A prophylactic effect includes delaying or eliminating the appearance of a disease or condition, delaying or eliminating the onset of symptoms of a disease or condition, slowing, halting, or reversing the progression of a disease or condition, or any combination thereof.
[0064] The term "co-administration," "administered in combination with," and their grammatical equivalents, as used herein, encompass administration of two or more agents to an animal, including humans, so that both agents and/or their metabolites are present in the subject at the same time. Co-administration includes simultaneous administration in separate compositions, administration at different times in separate compositions, or administration in a composition in which both agents are present.
[0065] The terms "antagonist" and "inhibitor" are used interchangeably, and they refer to a compound having the ability to inhibit a biological function (e.g., activity, expression, binding, protein-protein interaction) of a target protein (e.g., K-Ras, H-Ras or N-Ras G12C). Accordingly, the terms "antagonist" and "inhibitor" are defined in the context of the biological role of the target protein. While preferred antagonists herein specifically interact with (e.g., bind to) the target, compounds that inhibit a biological activity of the target protein by interacting with other members of the signal transduction pathway of which the target protein is a member are also specifically included within this definition. A preferred biological activity inhibited by an antagonist is associated with the development, growth, or spread of a tumor.
[0066] The term "agonist" as used herein refers to a compound having the ability to initiate or enhance a biological function of a target protein, whether by inhibiting the activity or expression of the target protein. Accordingly, the term "agonist" is defined in the context of the biological role of the target polypeptide. While preferred agonists herein specifically interact with (e.g., bind to) the target, compounds that initiate or enhance a biological activity of the target polypeptide by interacting with other members of the signal transduction pathway of which the target polypeptide is a member are also specifically included within this definition.
[0067] "Signal transduction" is a process during which stimulatory or inhibitory signals are transmitted into and within a cell to elicit an intracellular response. A modulator of a signal transduction pathway refers to a compound which modulates the activity of one or more cellular proteins mapped to the same specific signal transduction pathway. A modulator may augment (agonist) or suppress (antagonist) the activity of a signaling molecule.
[0068] An "anti-cancer agent", "anti-tumor agent" or "chemotherapeutic agent" refers to any agent useful in the treatment of a neoplastic condition. One class of anti-cancer agents comprises chemotherapeutic agents. "Chemotherapy" means the administration of one or more
chemotherapeutic drugs and/or other agents to a cancer patient by various methods, including intravenous, oral, intramuscular, intraperitoneal, intravesical, subcutaneous, transdermal, buccal, or inhalation or in the form of a suppository. [0069] The term "cell proliferation" refers to a phenomenon by which the cell number has changed as a result of division. This term also encompasses cell growth by which the cell morphology has changed (e.g., increased in size) consistent with a proliferative signal.
[0070] The term "selective inhibition" or "selectively inhibit" refers to a biologically active agent refers to the agent's ability to preferentially reduce the target signaling activity as compared to off-target signaling activity, via direct or indirect interaction with the target.
[0071] "Subject" refers to an animal, such as a mammal, for example a human. The methods described herein can be useful in both human therapeutics and veterinary applications. In some embodiments, the subject is a mammal, and in some embodiments, the subject is human.
"Mammal" includes humans and both domestic animals such as laboratory animals and household pets (e.g., cats, dogs, swine, cattle, sheep, goats, horses, rabbits), and non-domestic animals such as wildlife and the like.
[0072] "Prodrug" is meant to indicate a compound that may be converted under physiological conditions or by solvolysis to a biologically active compound described herein (e.g., compound of Formula (I), (I- A), (I-B), (I-C), (II), (II- A), (II-B), or (II-C)). Thus, the term "prodrug" refers to a precursor of a biologically active compound that is pharmaceutically acceptable. In some aspects, a prodrug is inactive when administered to a subject but is converted in vivo to an active compound, for example, by hydrolysis. The prodrug compound often offers advantages of solubility, tissue compatibility or delayed release in a mammalian organism (see, e.g., Bundgard, H., Design of Prodrugs (1985), pp. 7-9, 21-24 (Elsevier, Amsterdam); Higuchi, T., et al., "Pro-drugs as Novel Delivery Systems," (1987) A.C.S. Symposium Series, Vol. 14; and
Bioreversible Carriers in Drug Design, ed. Edward B. Roche, American Pharmaceutical
Association and Pergamon Press) each of which is incorporated in full by reference herein. The term "prodrug" is also meant to include any covalently bonded carriers, which release the active compound in vivo when such prodrug is administered to a mammalian subject. Prodrugs of an active compound, as described herein, are typically prepared by modifying functional groups present in the active compound in such a way that the modifications are cleaved, either in routine manipulation or in vivo, to the parent active compound. Prodrugs include compounds wherein a hydroxy, amino or mercapto group is bonded to any group that, when the prodrug of the active compound is administered to a mammalian subject, cleaves to form a free hydroxy, free amino or free mercapto group, respectively. Examples of prodrugs include, but are not limited to, acetate, formate and benzoate derivatives of a hydroxy functional group, or acetamide, formamide and benzamide derivatives of an amine functional group in the active compound and the like.
[0073] The term "in vivo" refers to an event that takes place in a subject's body. [0074] The term "in vitro" refers to an event that takes places outside of a subject's body. For example, an in vitro assay encompasses any assay run outside of a subject. In vitro assays encompass cell-based assays in which cells alive or dead are employed. In vitro assays also encompass a cell-free assay in which no intact cells are employed.
[0075] The disclosure is also meant to encompass the in vivo metabolic products of the disclosed compounds. Such products may result from, for example, the oxidation, reduction, hydrolysis, amidation, esterification, and the like of the administered compound, primarily due to enzymatic processes. Accordingly, the disclosure includes compounds produced by a process comprising administering a compound of this disclosure to a mammal for a period of time sufficient to yield a metabolic product thereof. Such products are typically identified by administering a
radiolabeled compound of the disclosure in a detectable dose to an animal, such as rat, mouse, guinea pig, monkey, or to human, allowing sufficient time for metabolism to occur, and isolating its conversion products from the urine, blood or other biological samples.
[0076] The chemical naming protocol and structure diagrams used herein are a modified form of the I.U.P.A.C. nomenclature system, using the ACD/Name Version 9.07 software program and/or ChemDraw Ultra Version 11.0.1 software naming program (CambridgeSoft). For complex chemical names employed herein, a substituent group is typically named before the group to which it attaches. For example, cyclopropylethyl comprises an ethyl backbone with a cyclopropyl substituent. Except as described below, all bonds are identified in the chemical structure diagrams herein, except for all bonds on some carbon atoms, which are assumed to be bonded to sufficient hydrogen atoms to complete the valency.
[0077] The present disclosure provides compounds that are capable of selectively binding to and/or modulating a Ras protein. In some embodiments, the Ras protien includes but is not limited to a mutant K-Ras, H-Ras or N-Ras protein. In some embodiments, the compounds modulate the Ras protein by binding to or interacting with one or more amino acids and/or one or more metal ions. Some subject compounds may also perturb the switch I conformation. The binding of these compounds may disrupt Ras (non-limiting examples include, K-Ras, H-Ras or N-Ras) downstream signaling.
[0078] In certain aspects, the present disclosure provides a compound of Formula (I):

[0162] The term " atropisomer s" refers to conformational stereoisomers which occur when rotation about a single bond in the molecule is prevented, or greatly slowed, as a result of steric interactions with other parts of the molecule and the substituents at both ends of the single bond are asymmetrical (i.e., optical activity arises without requiring an asymmetric carbon center or stereocenter). Where the rotational barrier about the single bond is high enough, and interconversion between conformations is slow enough, separation and isolation of the isomeric species may be permitted. Atropisomers are enantiomers (or epimers) without a single asymmetric atom. By one definition, atropisomerism is defined to exist where the isomers have a half-life (ti/2) of at least 1000 seconds, which is a free energy barrier of 22.3 kcal mol"1 (93.3 kJ mol"1) at 300 K (Oki, M., "Recent Advances in Atropisomerism," Topics in Stereochemistry (1983) 14: 1). The atropisomers are considered stable if the barrier to interconversion is high enough to permit the atropisomers to undergo little or no interconversion at room temperature for at least a week, preferably at least a year. In some embodiments, an atropisomeric compound of the disclosure does not undergo more than about 5% interconversion to its opposite atropisomer at room temperature during one week when the atropisomeric compound is in substantially pure form, which is generally a solid state. In some embodiments, an atropisomeric compound of the disclosure does not undergo more than about 5% interconversion to its opposite atropisomer at room temperature (approximately 25 °C) during one year. Preferably, the atropisomeric compounds of the disclosure are stable enough to undergo no more than about 5%
interconversion in an aqueous pharmaceutical formulation held at 0 °C for at least one week. The present chemical entities, pharmaceutical compositions and methods are meant to include all such possible atropisomers, including racemic mixtures, diastereomeric mixtures, epimeric mixtures, optically pure forms of single atropisomers, and intermediate mixtures.
[0163] The energy barrier to thermal racemization of atropisomers may be determined by the steric hindrance to free rotation of one or more bonds forming a chiral axis. Certain biaryl compounds exhibit atropisomerism where rotation around an interannular bond lacking C2 symmetry is restricted. The free energy barrier for isomerization (enantiomerization) is a measure of the stability of the interannular bond with respect to rotation. Optical and thermal excitation can promote racemization of such isomers, dependent on electronic and steric factors.
[0164] Ortho- substituted biaryl compounds may exhibit this type of conformational, rotational isomerism. Such biaryls are enantiomeric, chiral atropisomers where the sp 2 -sp 2 carbon-carbon, interannular bond between the aryl rings has a sufficiently high energy barrier to prevent free rotation, and where substituents 1≠W2 and W 3≠W 4 render the molecule asymmetric.
Figure imgf000079_0001
[0165] The steric interaction between W^W3, W^W4, and/or W2:W4, W2:W3 is large enough to make the planar conformation an energy maximum. Two non-planar, axially chiral enantiomers then exist as atropisomers when their interconversion is slow enough such that they can be isolated free of each other. Bold lines and dashed lines in the figures shown above indicate those moieties, or portions of the molecule, which are sterically restricted due to a rotational energy barrier. Bolded moieties exist orthogonally above the plane of the page, and dashed moieties exist orthogonally below the plane of the page. The 'flat' part of the molecule (the left ring in each of the two depicted biaryls) is in the plane of the page.

After 30 min incubation at room temperature, the exchange reaction was initiated by addition of 3 μΐ^ SOS(cat) (catalytic domain, 2.5 μΜ stock in protein dilution buffer, 0.5 μΜ final). The assay was carried out in black low-volume plates (Corning #4514) and fluorescence was monitored (485nm excitation and 510nm emission) for 45 minutes after initiation at 60- s intervals.
[0325] For data analysis, relative fluorescence values for each sample after subtracting the background values (before SOS addition) were plotted in graph pad. Rates were then calculated by fitting the data by non- linear regression (one phase association curve). Typically, 6 dilutions per compound (3-fold series, starting at 60 μΜ final) were measured. Calculated rates vs compound concentrations were fitted by non-linear regression (log(inhibitor) vs response- Variable slope (four parameters) fit) to determine IC50 values.
