Description

[Technical field]

[0001] Field The present application relates to novel bicyclic substituted sulfonylurea compounds and analogs, the preparation of said compounds and analogs, pharmaceutical compositions comprising said compounds and analogs, and their use as medicaments for treating diseases associated with the regulation of cytokines such as IL-1β and IL-18, diseases associated with the regulation of NLRP3, or diseases associated with the inhibition of activation of NLRP3 or of related components of the inflammatory process. [Background technology]

[0002] background Nucleotide-binding oligomerization domain-like receptors (or NOD-like receptors, NLRs) belong to a family of pattern recognition receptors that function as intracellular sensors of pathogen-associated molecular patterns (PAMPs) and damage-associated molecular patterns (DAMPs). Accumulating evidence indicates that NLRs play an important role in the innate immune response to infection and cellular damage. Among the numerous NOD-like receptors, NLR pyrin domain-containing 3 (NLRP3) has been well characterized in inflammasome formation.

[0003] NLRP3 is expressed primarily in macrophages and in several other cell types with some tissue specificity. Formation of the NLRP3 inflammasome activates caspase-1, which catalyzes proteolytic reactions and releases proinflammatory cytokines such as interleukin-1β (IL-1β) and IL-18 [Nat Rev Immunol. 2013 Jun;13(6)]. Inflammasome activation is also associated with pyroptosis, a rapid and proinflammatory form of cell death mediated by membrane pore-forming gasdermin D fragments.

[0004] Dysregulated inflammasome activation has been shown to be involved in the pathogenesis of several human diseases. Most notably, gain-of-function mutations in NLRP3 cause genetic diseases characterized by IL-1β-mediated systemic inflammation, such as cryopyrin-associated periodic syndrome (CAPS). In addition, aberrant activation of the NLRP3 inflammasome exacerbates chronic human diseases such as neurodegenerative disorders (multiple sclerosis, AD, and PD), metabolic disorders (atherosclerosis and type 2 diabetes), and inflammatory syndromes (gout flares and osteoarthritis). In recent years, the role of NLRP3 in the initiation and progression of cancer has been documented [Nat Immunol. 2021 Mar 11. doi:10.1038 / s41590-021-00886-5 (Non-Patent Document 2)].

[0005] Therapeutically targeting the NLRP3 / IL-1β innate immune pathway has proven successful based on findings from the CANTOS study, where treatment with canakinumab (a monoclonal antibody against IL-1β) resulted in a significantly lower rate of recurrent cardiovascular events, demonstrating a clear benefit of targeting inflammation in high-risk patients with cardiovascular disease. Targeting NLRP3 activation with small molecules is also feasible, as exemplified by MCC950, which directly interacts with the Walker B motif within the NLRP3 NACHT domain, blocks ATP hydrolysis, and inhibits NLRP3 activation and inflammasome formation [Nat Chem Biol. 2019 Jun; 15(6): 556-559 (Non-Patent Document 3)].

[0006] Therefore, inhibition of the NLRP3 / IL-1β innate immune pathway via small molecule modulators may be a useful and practical approach to treat and prevent genetic diseases (cryopyrin-associated periodic syndromes, CAPS), neurodegenerative disorders (multiple sclerosis, AD, and PD), metabolic disorders (atherosclerosis and type 2 diabetes), inflammatory syndromes (gout flares and osteoarthritis), cancer, among other relevant human diseases.

[0007] There is a need to provide compounds that have improved pharmaceutical properties and / or offer useful alternatives to known compounds, which can help achieve therapeutic efficacy while reducing undesirable side effects. [Prior art documents] [Non-patent literature]

[0013] In another aspect, the present technology provides methods of treating and / or managing various diseases and disorders, comprising administering to a patient a therapeutically effective amount of a compound provided herein or a pharma- ceutically acceptable form thereof (e.g., salts, hydrates, solvates, isomers, sterioisomers, enantiomers, prodrugs, and isotopically labeled derivatives). Non-limiting examples of diseases and disorders are described herein.

[0014] Also provided herein are pharmaceutical compositions (e.g., single unit dosage forms) that can be used in the methods provided herein. In one embodiment, the pharmaceutical compositions include a compound provided herein, or a pharma- ceutically acceptable form thereof (e.g., salts, hydrates, solvates, isomers, sterioisomers, prodrugs, and isotopically labeled derivatives).

[0015] While specific embodiments are discussed, this specification is illustrative only and not restrictive. Many variations of the disclosure will become apparent to those of skill in the art upon review of this specification.

[0016] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.

[0017] definition As used in this specification and the claims, the singular forms "a," "an," and "the" include plural referents unless the context clearly dictates otherwise.

[0018] As used herein, "agent", "biologically active agent", or "second active agent" refers to a biological, pharmaceutical, or chemical compound or another moiety. Non-limiting examples include simple or complex organic or inorganic molecules, peptides, proteins, oligonucleotides, antibodies, antibody derivatives, antibody fragments, vitamins, vitamin derivatives, carbohydrates, toxins, or chemotherapeutic compounds, and their metabolites. A variety of compounds can be synthesized, such as small molecules and oligomers (e.g., oligopeptides and oligonucleotides), as well as synthetic organic compounds based on a variety of core structures. In addition, a variety of natural sources can provide active compounds, such as, for example, plant or animal extracts. One of ordinary skill in the art can readily recognize that there is no limit as to the structural nature of the agents of the present disclosure.

[0019] "Administration" of the disclosed compounds includes delivery of a compound as described herein, or a prodrug or other pharma- ceutically acceptable derivative thereof, to a subject using any suitable formulation or route of administration, as discussed herein.

[0020] As used herein, the terms "co-administration," "administered in combination with," and their grammatical equivalents include administration of two or more agents to a subject such 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 separate times in separate compositions, or administration in a composition in which both agents are present.

[0021] The term "effective amount" or "therapeutically effective amount" refers to an amount of a compound or pharmaceutical composition described herein sufficient to affect the intended use, including but not limited to disease treatment, as set forth below. In some embodiments, the amount is effective for detectable inhibition of NLRP3, which can be determined, for example, by biological assays described herein. Therapeutically effective amounts can vary depending on the intended use (in vitro or in vivo), or the subject and disease state to be treated, such as the subject's weight and age, the severity of the disease state, the mode of administration, etc., which can be readily determined by one of ordinary skill in the art. The term also applies to a dose that will induce a response in target cells, such as reduced cell migration. A particular dose will vary depending, for example, on the compound selected, the species of the subject and their age / existing health conditions or risk to health conditions, the dosing regimen to be followed, the severity of the disease, whether it is administered in combination with other agents, the timing of administration, the tissue to which it is administered, and the physical delivery system to which it is delivered.

[0022] All methods described herein can be performed in any suitable order unless otherwise indicated herein or clearly contradicted by context.

[0023] As used herein, the terms "treatment," "treating," "alleviating," "managing," and "ameliorating" are used interchangeably herein. These terms refer to an approach to obtain beneficial or desired results, including but not limited to therapeutic benefit and / or preventative benefit. Therapeutic benefit refers to the eradication or amelioration of the underlying disease being treated. Therapeutic benefit is also achieved by the eradication or amelioration of one or more of the physiological symptoms associated with the underlying disease such that an improvement is observed in the patient, even though the patient may still suffer from the underlying disease. For preventative benefit, the pharmaceutical compounds and / or compositions may be administered to patients at risk of developing the disease or to patients who report one or more of the physiological symptoms of the disease, even if a diagnosis of the disease has not been made.

[0024] As used herein, the terms "preventing" and "prophylaxis" refer to administering a pharmaceutical compound or medicament, or a composition containing a pharmaceutical compound or medicament, to a subject before a disease, disorder, or condition fully manifests itself, to prevent the appearance and / or reduce the severity of one or more symptoms of a disease, disorder, or condition. Those skilled in the art will recognize that the term "prevent" is not an absolute term. It is understood in the medical field to refer to the prophylactic administration of a drug to reduce the likelihood or severity of a disease, disorder, or condition, or its symptoms, and this is the meaning of such terms as used in this disclosure.

[0025] A "therapeutic effect," as that term is used herein, encompasses therapeutic and / or prophylactic benefits 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.

[0026] "Subjects" to which administration is contemplated include, but are not limited to, humans (i.e., male or female of any age group, e.g., pediatric subjects (e.g., infants, children, adolescents) or adult subjects (e.g., young adults, middle-aged adults, or elderly adults)), and / or other primates (e.g., cynomolgus monkeys, rhesus monkeys); mammals, including commercially relevant mammals such as cows, pigs, horses, sheep, goats, cats, and / or dogs; and / or birds, including commercially relevant birds such as chickens, ducks, geese, quail, and / or turkeys.

[0027] The term "in vivo" refers to events that take place inside a subject's body. In vivo also includes events that occur in rodents, such as, for example, rats, mice, guinea pigs, etc.

[0028] The term "in vitro" refers to events that occur outside of a subject's body. For example, an in vitro assay includes any assay that is performed outside of a subject. In vitro assays include cell-based assays in which cells, living or dead, are used. In vitro assays also include cell-free assays in which no intact cells are used.

[0029] As used herein, the term "pharmaceutically acceptable salts" refers to those salts that are suitable for use in contact with the tissues of a subject without undue toxicity, irritation, allergic response, etc., within the scope of sound medical judgment, and are commensurate with a reasonable benefit / risk ratio. Pharmaceutically acceptable salts are well known in the art. For example, Berge et al. describe pharmaceutically acceptable salts in detail in J. Pharmaceutical Sciences (1977) 66:1-19. Pharmaceutically acceptable salts of the compounds provided herein include those derived from suitable inorganic and organic acids and bases. Examples of pharmaceutically acceptable non-toxic acid addition salts are salts of amino groups formed with inorganic acids such as hydrochloric acid, hydrobromic acid, phosphoric acid, sulfuric acid, and perchloric acid, or with organic acids such as acetic acid, oxalic acid, maleic acid, tartaric acid, citric acid, succinic acid, or malonic acid, or by using other methods used in the art, such as ion exchange. For example, pharma- ceutically acceptable salts include adipate, alginate, ascorbate, aspartate, benzenesulfonate, besylate, benzoate, bisulfate, borate, butyrate, camphorate, camphorsulfonate, citrate, cyclopentanepropionate, digluconate, dodecyl sulfate, ethanesulfonate, formate, fumarate, glucoheptonate, glycerophosphate, gluconate, hemisulfate, heptanoate, hexanoate, hydroiodide, 2-hydroxy-ethanesulfonate, and the like. Examples of the salts include phonate, lactobionate, lactate, laurate, lauryl sulfate, malate, maleate, malonate, methanesulfonate, 2-naphthalenesulfonate, nicotinate, nitrate, oleate, oxalate, palmitate, pamoate, pectinate, persulfate, 3-phenylpropionate, phosphate, picrate, pivalate, propionate, stearate, succinate, sulfate, tartrate, thiocyanate, p-toluenesulfonate, undecanoate, and valerate.In some embodiments, organic acids from which salts may be derived include, for example, acetic acid, propionic acid, glycolic acid, pyruvic acid, oxalic acid, lactic acid, trifluoroacetic 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.

[0030] The salts can be prepared in situ during the isolation and purification of the disclosed compounds, or separately, such as by reacting the free base or free acid of the parent compound with a suitable base or acid, respectively. Pharmaceutically acceptable salts derived from appropriate bases include alkali metal, alkaline earth metal, ammonium, and N + (C 1~4 Alkyl) 4 Examples of pharmaceutically acceptable salts include salts of sodium, lithium, potassium, calcium, magnesium, iron, zinc, copper, manganese, aluminum, and the like. In addition, pharmaceutically acceptable salts include non-toxic ammonium, quaternary ammonium, and amine cations, formed using counterions such as halides, hydroxides, carboxylates, sulfates, phosphates, nitrates, lower alkyl sulfonates, and aryl sulfonates, where appropriate. 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, for example, isopropylamine, trimethylamine, diethylamine, triethylamine, tripropylamine, and ethanolamine. In some embodiments, the pharmaceutically acceptable base addition salts can be selected from ammonium, potassium, sodium, calcium, and magnesium salts.

[0031] As used herein, the term "solvate" refers to a compound further comprising a stoichiometric or non-stoichiometric amount of a solvent bound by non-covalent intermolecular forces. The solvate may consist of the disclosed compound, or a pharma- ceutically acceptable salt thereof. When the solvent is water, the solvate is a "hydrate". Pharmaceutically acceptable solvates and hydrates are complexes that may contain, for example, 1 to about 100, or 1 to about 10, or 1 to about 2, about 3, or about 4 solvent or water molecules. As used herein, the term "compound" will be understood to include compounds and solvates of compounds, as well as mixtures thereof.

[0032] In some embodiments, the pharma- ceutically acceptable form is a prodrug. As used herein, the term "prodrug" refers to a compound that is transformed in vivo to produce a pharma- ceutically acceptable form of the disclosed compound or compounds. A prodrug may be inactive when administered to a subject, but is converted to an active compound in vivo, for example, by hydrolysis (e.g., hydrolysis in blood). In certain cases, a prodrug has improved physical and / or delivery properties relative to the parent compound. A prodrug can increase the bioavailability of a compound when administered to a subject (e.g., by allowing enhanced absorption into the blood after oral administration) or enhance delivery to a biological compartment of interest (e.g., the brain or lymphatic system) compared to the parent compound. Exemplary prodrugs include derivatives of the disclosed compounds that have enhanced aqueous solubility or active transport across the intestinal membrane compared to the parent compound.

[0033] Prodrug compounds often offer advantages of solubility, tissue compatibility, or delayed release in the mammalian organism (see, e.g., Bundgard, H., Design of Prodrugs (1985), pp. 7-9, 21-24 (Elsevier, Amsterdam). Reviews of prodrugs are provided in Higuchi, T., et al., “Pro-drugs as Novel Delivery Systems,” ACS Symposium Series, Vol. 14, and in Bioreversible Carriers in Drug Design, ed. Edward B. Roche, American Pharmaceutical Association and Pergamon Press, 1987, both of which are incorporated herein by reference in their entireties. Exemplary advantages of a prodrug can include, but are not limited to, its physical properties, such as enhanced aqueous solubility for parenteral administration at physiological pH compared to the parent compound, or it can enhance absorption from the digestive tract or enhance drug stability for long-term storage.

[0034] The term "prodrug" is also meant to include any covalently bonded carrier that releases an active compound in vivo when such a prodrug is administered to a subject. Prodrugs of active compounds as described herein can be prepared by modifying functional groups present in the active compound in such a way that the modifications are cleaved to the parent active compound, either in routine manipulation or in vivo. Prodrugs include compounds in which a hydroxy, amino, or mercapto group is bonded to any group that cleaves to form a free hydroxy, free amino, or free mercapto group, respectively, when a prodrug of the active compound is administered to a subject. Examples of prodrugs include, but are not limited to, acetate, formate, and benzoate derivatives of alcohols, such as in active compounds, or acetamide, formamide, and benzamide derivatives of amine functional groups. Other examples of prodrugs include compounds that contain -NO, -NO2, -ONO, or -ONO2 moieties. Prodrugs can typically be prepared using well-known methods, such as those described in Burger's Medicinal Chemistry and Drug Discovery, 172-178, 949-982 (Manfred E. Wolff ed., 5th ed., 1995), and Design of Prodrugs (H. Bundgaard ed., Elselvier, New York, 1985).

[0035] For example, if a disclosed compound, or a pharma- ceutically acceptable form of the compound, contains a carboxylic acid functional group, the prodrug may be a compound that is a combination of a hydrogen atom of the acid group and (C 1~8 ) alkyl, (C 1~12)alkanoyloxymethyl, 1-(alkanoyloxy)ethyl having 4 to 9 carbon atoms, 1-methyl-1-(alkanoyloxy)-ethyl having 5 to 10 carbon atoms, alkoxycarbonyloxymethyl having 3 to 6 carbon atoms, 1-(alkoxycarbonyloxy)ethyl having 4 to 7 carbon atoms, 1-methyl-1-(alkoxycarbonyloxy)ethyl having 5 to 10 carbon atoms, N-(alkoxycarbonyl)aminomethyl having 3 to 9 carbon atoms, 1-(N-(alkoxycarbonyl)amino)ethyl having 4 to 10 carbon atoms, 3-phthalidyl, 4-crotonolactonyl, gamma-butyrolactone-4-yl, di-N,N-(C 1~2 ) Alkylamino(C 2~3 ) alkyl (e.g., [3-dimethylaminoethyl), carbamoyl-(C 1~2 ) alkyl, N,N-di(C 1~2 ) alkylcarbamoyl-(C 1~2 ) alkyl, and piperidino-, pyrrolidino-, or morpholino (C 2~3 ) alkyl, or other groups may be substituted to form pharma- ceutically acceptable esters.

[0036] Similarly, when the disclosed compounds contain an alcohol functional group, the prodrug may be a compound that is a hydrogen atom of the alcohol group and a (C 1~6 ) alkanoyloxymethyl, 1-((C 1~6 )alkanoyloxy)ethyl, 1-methyl-1-((C 1~6 )alkanoyloxy)ethyl, (C 1~6 ) alkoxycarbonyloxymethyl, N-(C 1~6 ) alkoxycarbonylaminomethyl, succinoyl, (C 1~6 ) Alkanoyl, α-amino (C 1~4 ) alkanoyl, arylacyl, and each α-aminoacyl group is independently selected from the naturally occurring L-amino acids, -P(O)(OH), -P(O)(O(C 1~6) alkyl) 2, or glycosyl (the radical resulting from removal of the hydroxyl group of a carbohydrate in the hemiacetal form), such as α-aminoacyl or α-aminoacyl-α-aminoacyl.

[0037] When the disclosed compounds incorporate an amine functional group, the prodrug can be a prodrug that is a combination of a hydrogen atom in the amine group and a cyclic alkyl group in which R and R′ are each independently: 1~10 ) alkyl, (C 3~7 ) R-carbonyl, RO-carbonyl, NRR′-carbonyl, Y selected from cycloalkyl, benzyl, natural α-aminoacyl or natural α-aminoacyl-natural α-aminoacyl 1 But, H, (C 1~6 ) alkyl, or benzyl, -C(OH)C(O)OY 1 ;Y 2 However, (C 1~4 ) alkyl, and Y 3 However, (C 1~6 ) alkyl, carboxy (C 1~6 ) Alkyl, Amino (C 1~4 ) alkyl, or mono-N- or di-N,N-(C 1~6 ) alkylaminoalkyl, —C(OY 2 )Y 3 ; and Y 4 is H or methyl, and Y 5 However, mono-N- or di-N-(C 1 6 ) alkylamino, morpholino, piperidin-1-yl, or pyrrolidin-1-yl; 4 )Y 5 The substituents may be formed by replacement with groups such as:

[0038] In some embodiments, the disclosed compounds may include isomers. "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. As used herein, the term "isomer" includes any and all geometric and stereoisomers. For example, "isomers" include geometric double bond cis and trans isomers, also referred to as E and Z isomers, R and S enantiomers, diastereomers, (d) isomers and (l) isomers, racemic mixtures thereof, and other mixtures thereof as fall within the scope of the present disclosure.

[0039] Geometric isomers are represented by symbols representing bonds which may be single, double, or triple bonds as described herein. TIFF2025508790000006.tif2128. Provided herein are various geometric isomers and mixtures thereof resulting from the arrangement of substituents around a carbon-carbon double bond or the arrangement of substituents around a carbon ring. Substituents around a carbon-carbon double bond are designated as being in the "Z" or "E" configuration, and the terms "Z" and "E" are used in accordance with IUPAC standards. Unless otherwise specified, structures depicting double bonds encompass both the "E" and "Z" isomers.

[0040] Alternatively, substituents around a carbon-carbon double bond may be designated as "cis" or "trans", with "cis" representing substituents on the same side of the double bond and "trans" representing substituents on opposite sides of the double bond. The arrangement of substituents around a carbocyclic ring may also be designated as "cis" or "trans". The term "cis" represents substituents on the same side of the plane of the ring and the term "trans" represents substituents on opposite sides of the plane of the ring. Mixtures of compounds in which substituents are located both on the same and opposite sides of the plane of the ring are designated as "cis / trans".

[0041] "Enantiomers" are a pair of stereoisomers that are non-superimposable mirror images of each other. A mixture of a pair of enantiomers in any ratio may be known as a "racemic" mixture. The term "(±)" is used to designate a racemic mixture when necessary. "Diastereoisomers" are stereoisomers that have at least two asymmetric atoms but are not mirror images of each other. Absolute stereochemistry is specified according to the Cahn-Ingold-Prelog RS system. When a compound is an enantiomer, the stereochemistry at each chiral carbon may be specified by either R or S. A resolved compound of unknown absolute configuration may be designated as (+) or (-) depending on the direction (dextrorotatory or levorotatory) that the compound rotates plane polarized light at the wavelength of the sodium D line. Certain compounds described herein contain one or more asymmetric centers and may therefore give rise to enantiomers, diastereomers, and other stereoisomeric forms that may be defined as (R)- or (S)- in terms of the absolute stereochemistry at each asymmetric atom. The present chemical entities, pharmaceutical compositions and methods are meant to include all such possible isomers, including racemic mixtures, optically substantially pure forms, and intermediate mixtures. Optically active (R)- and (S)-isomers may be prepared, for example, using chiral synthons or chiral reagents, or resolved using conventional techniques.

[0042] In some embodiments, an enantiomer is provided partially or substantially free of the corresponding enantiomer and may be referred to as "optically enriched," "enantiomerically enriched," "enantiomerically pure," and "non-racemic," as used interchangeably herein. The "enantiomeric excess" or "% enantiomeric excess" of a composition may be calculated using the equation shown below. In the example shown below, the composition contains 90% of one enantiomer, e.g., the S enantiomer, and 10% of the other enantiomer, e.g., the R enantiomer. ee=(90-10) / 100=80%. Thus, a composition containing 90% of one enantiomer and 10% of the other is said to have an enantiomeric excess of 80%. In some embodiments, the compositions described herein contain an enantiomeric excess of at least about 50%, at least about 60%, at least about 70%, at least about 80%, at least about 90%, at least about 95%, at least about 98%, at least about 99%, or at least about 99.5% of the S enantiomer, or a range between and including any two of the foregoing values ​​(e.g., 50-99.5% ee). In other words, the composition contains an enantiomeric excess of the S enantiomer over the R enantiomer. In other embodiments, some compositions described herein contain an enantiomeric excess of at least about 50%, at least about 60%, at least about 70%, at least about 80%, at least about 90%, at least about 95%, at least about 98%, at least about 99%, or at least about 99.5% of the R enantiomer, or a range between any two of the foregoing values ​​(e.g., 50-99.5% ee). In other words, the composition contains an enantiomeric excess of the R enantiomer over the S enantiomer. When the enrichment of one enantiomer is much greater than about 80% by weight, the composition is referred to as a "substantially enantiomerically enriched," "substantially enantiomerically pure," or "substantially non-racemic" preparation.

[0043] Thus, a composition containing 90% of one enantiomer and 10% of the other is said to have an enantiomeric excess of 80%. In some embodiments, the compositions described herein contain an enantiomeric excess of at least about 50%, at least about 60%, at least about 70%, at least about 80%, at least about 90%, at least about 95%, at least about 98%, at least about 99%, or at least about 99.5% of the S enantiomer, or a range between and including any two of the foregoing values ​​(e.g., 50-99.5% ee). In other words, the composition contains an enantiomeric excess of the S enantiomer over the R enantiomer. In other embodiments, some compositions described herein contain an enantiomeric excess of at least about 50%, at least about 60%, at least about 70%, at least about 80%, at least about 90%, at least about 95%, at least about 98%, at least about 99%, or at least about 99.5% of the R enantiomer, or a range between any two of the foregoing values ​​(e.g., 50-99.5% ee). In other words, the composition contains an enantiomeric excess of the R enantiomer over the S enantiomer. When the enrichment of one enantiomer is much greater than about 80% by weight, the composition is referred to as a "substantially enantiomerically enriched," "substantially enantiomerically pure," or "substantially non-racemic" preparation.

[0044] Optical isomers can be obtained by resolution of racemic mixtures according to conventional processes, for example, by formation of diastereoisomeric salts, by treatment with optically active acids or bases. Examples of suitable acids include, but are not limited to, tartaric acid, diacetyltartaric acid, dibenzoyltartaric acid, ditoluoyltartaric acid, and camphorsulfonic acid. Separation of the diastereoisomeric mixtures by crystallization, followed by liberation of the optically active bases from these salts, results in separation of the isomers. Another method involves the synthesis of covalent diastereoisomeric molecules by reacting the disclosed compounds with optically pure acids in activated form or optically pure isocyanates. The synthesized diastereoisomers can be separated by conventional means such as chromatography, distillation, crystallization, or sublimation, and then hydrolyzed to deliver enantiomerically enriched compounds. Optically active compounds can also be obtained by using active starting materials. In some embodiments, these isomers can be in the form of free acids, free bases, esters, or salts.

[0045] In any embodiment, the pharma- ceutically acceptable form is a tautomer. As used herein, the term "tautomer" is a type of isomer that includes two or more interconvertible compounds resulting from the formal migration of at least one of the hydrogen atoms and at least one change in valence (e.g., a single bond to a double bond, a triple bond to a single bond, or vice versa). "Tautomerism" includes prototropic tautomerism or proton transfer tautomerism, which is considered a subset of acid-base chemistry. "Prototropic tautomerism" or "proton transfer tautomerism" involves the migration of a proton with a change in bond order. The exact ratio of tautomers depends on several factors, including temperature, solvent, and pH. When tautomerism is possible (e.g., in a solution), a chemical equilibrium of the tautomers may be reached. Tautomerism (i.e., the reaction that provides the tautomeric pair) may be catalyzed by an acid or base, or may occur without the action or presence of an external agent. Exemplary tautomers include, but are not limited to, keto to enol, amide to imide, lactam to lactim, enamine to imine, and enamine to (different) enamine tautomers. A specific example of keto-enol tautomerism is the interconversion of the tautomers of pentane-2,4-dione and 4-hydroxypent-3-en-2-one. Another example of tautomerism is phenol-keto tautomerism. A specific example of phenol-keto tautomerism is the interconversion of the tautomers of pyridin-4-ol and pyridin-4(1H)-one.

[0046] Unless otherwise stated, structures depicted herein are also meant to include compounds that differ only in the presence of one or more isotopically enriched atoms. For example, the replacement of a hydrogen by deuterium or tritium, or 13 C- or 14 Compounds having this structure, except for the replacement of a carbon with a C-enriched carbon, are within the scope of this disclosure.

[0047] The present disclosure also encompasses pharma- ceutically acceptable forms that are "isotopically labeled derivatives," which are the same compounds as enumerated herein except that one or more atoms have been replaced by an atom having an atomic mass or mass number different from the atomic mass or mass number normally found in nature. Examples of isotopes that can be incorporated into the disclosed compounds include, respectively: 2 H, 3 H, 13 C 14 C. 15 N, 18 O. 17 O. 31 P, 32 P, 35 S, 18 F, and 36 Included are isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorus, and chlorine, such as Cl. Certain isotopically labeled disclosed compounds (e.g., 3 H and 14 C) are useful in compound and / or substrate tissue distribution assays. 3 H) and carbon 14 (i.e. 14 C) isotopes can allow for ease of preparation and detectability. Additionally, deuterium (i.e., 2 Substitution with heavier isotopes such as H) can confer certain therapeutic benefits (e.g., increased in vivo half-life or reduced dose requirements) due to greater metabolic stability. Isotopically labeled disclosed compounds can generally be prepared by substituting an isotopically labeled reagent with a non-isotopically labeled reagent. In some embodiments, compounds are provided herein that can also contain unnatural proportions of atomic isotopes at one or more of the atoms that constitute such compounds. All isotopic variations of compounds as disclosed herein, whether radioactive or not, are encompassed within the scope of the disclosure. In some embodiments, radiolabeled compounds are useful for studying the metabolism and / or tissue distribution of compounds, or for altering the rate or pathway of metabolism or other aspects of biological function.

[0063] An N-containing heterocyclyl moiety refers to a non-aromatic group in which at least one of the ring atoms is a nitrogen atom. The heteroatom(s) in the heterocyclyl radical may be optionally oxidized. One or more nitrogen atoms, if present, may be optionally quaternized. Heterocyclyl also includes ring systems substituted with one or more nitrogen oxide (-O-) substituents, such as piperidinyl N-oxide. A heterocyclyl is attached to the parent molecular structure through any atom of any of the ring(s).

[0064] "Heterocyclyl" also includes ring systems in which a heterocyclyl ring, as defined above, is fused to one or more carbocyclyl groups, with the point of attachment being on either the carbocyclyl or heterocyclyl ring, or in which a heterocyclyl ring, as defined above, is fused to one or more aryl or heteroaryl groups, with the point of attachment to the parent molecular structure being on the heterocyclyl ring. In some embodiments, a heterocyclyl group is a 5-14 membered non-aromatic ring system having one or more ring carbon atoms and one to four ring heteroatoms, each heteroatom being independently selected from nitrogen, oxygen, phosphorus, and sulfur ("5-14 membered heterocyclyl"). In some embodiments, a heterocyclyl group is a 3-10 membered non-aromatic ring system having one or more ring carbon atoms and one to four ring heteroatoms, each heteroatom being independently selected from nitrogen, oxygen, phosphorus, and sulfur ("3-10 membered heterocyclyl"). In some embodiments, a heterocyclyl group is a 5-8 membered non-aromatic ring system having one or more ring carbon atoms and one to four ring heteroatoms, each of which is independently selected from nitrogen, oxygen, phosphorus, and sulfur ("5-8 membered heterocyclyl"). In some embodiments, a heterocyclyl group is a 5-6 membered non-aromatic ring system having one or more ring carbon atoms and one to four ring heteroatoms, each of which is independently selected from nitrogen, oxygen, phosphorus, and sulfur ("5-6 membered heterocyclyl"). In some embodiments, a 5-6 membered heterocyclyl has one to three ring heteroatoms, each of which is independently selected from nitrogen, oxygen, phosphorus, and sulfur. In some embodiments, a 5-6 membered heterocyclyl has one to two ring heteroatoms, each of which is independently selected from nitrogen, oxygen, phosphorus, and sulfur. In some embodiments, a 5-6 membered heterocyclyl has one ring heteroatom, each of which is independently selected from nitrogen, oxygen, phosphorus, and sulfur.

[0065] A "heterocyclyl" may contain one or more ketone groups (-C(=O)-) as part of the ring. Examples of ketone-containing heterocycles include, but are not limited to, pyridin-2(1H)-one, pyrazin-2(1H)-one, pyrimidin-2(1H)-one, pyrimidin-4(3H)-one, pyridazin-3(2H)-one, pyridin-4(1H)-one, imidazolidin-2-one, 1,3-dihydro-2H-imidazol-2-one, 2,4-dihydro-3H-1,2,4-triazol-3-one, oxazol-2(3H)-one, and oxazolidin-2-one. Ketone-containing heterocyclyls are accessible by removing a hydrogen atom from the corresponding corepsonding ketone-containing heterocycle at any available NH or CH position.

[0067] Unless stated otherwise specifically, a heterocyclyl group may be optionally substituted with one or more of the substituents disclosed herein.

[0068] Substituents, when specified by their conventional chemical formula written from left to right, equally encompass the chemically identical substituents that would result from writing the structure from right to left, e.g., -CH2O- is equivalent to -OCH2-.

[0069] A "leaving group or atom" is any group or atom that, under reaction conditions, is cleaved from a starting material, thereby facilitating reaction at a particular site. Suitable non-limiting examples of such groups, unless otherwise specified, include halogen atoms, mesyloxy, p-nitrobenzenesulfonyloxy, trifluoromethyloxy, and tosyloxy groups.

[0070] "Protecting group" has the meaning traditionally associated with it in organic synthesis, namely, a group that selectively blocks one or more reactive sites in a multifunctional compound so that a chemical reaction can be selectively performed at an otherwise unprotected reactive site, and the group can be easily removed after the selective reaction is complete. Non-limiting examples of functional groups that can be masked by a protecting group include amine, hydroxy, thiol, carboxylic acid, and aldehyde. For example, a hydroxy-protected form is when at least one of the hydroxy groups present in a compound is protected by a hydroxy-protecting group. Various protecting groups are disclosed, for example, in Greene's Protective Groups in Organic Synthesis, Fifth Edition, Wiley (2014), which is incorporated herein by reference in its entirety. For additional background information regarding protecting group methodology (materials, methods, and strategies for protection and deprotection) and other synthetic chemical transformations useful to generate the compounds described herein, see R. Larock, Comprehensive organic Transformations, VCH Publishers (1989), Greene's Protective Groups in Organic Synthesis, Fifth Edition, Wiley (2014), L. Fieser and M. Fieser, Fieser and Fieser's Reagents for Organic Synthesis, John Wiley and Sons (1994), and L. Paquette, ed., Encyclopedia of Reagents for Organic Synthesis, John Wiley and Sons (1995). These references are incorporated herein by reference in their entireties.

[0071] The term "substituted" or "substitution" means that at least one hydrogen present on a group atom (e.g., a carbon or nitrogen atom) is replaced with an acceptable substituent, e.g., a substituent that, upon replacement with hydrogen, results in a stable compound, e.g., a compound that does not spontaneously undergo transformation, such as by rearrangement, cyclization, elimination or other reaction. Unless otherwise specified, a "substituted" group can have a substituent at one or more substitutable positions of the group, and when more than one position in any given structure is substituted, the substituents are either the same or different at each position. Substituents include acyl, alkyl, alkenyl, alkynyl, alkoxy, alkylaryl, cycloalkyl, aralkyl, aryl, aryloxy, amino, amido, amidino, imino, azide, carbonate, carbamate, carbonyl, heteroalkyl, heteroaryl, heteroarylalkyl, heterocycloalkyl, hydroxy, cyano, halo, haloalkoxy, haloalkyl, ester, ether, mercapto, thio, alkylthio, arylthio, thiocarbonyl, nitro, oxo, phosphate, phosphonate, phosphinate, silyl, sulfinyl, sulfonyl, sulfonamidyl, sulfoxyl, sulfonate, urea, -Si(R a )3, -OR a , -SR a , -OC(O)-R a , -N(R a )2, -C(O)R a , -C(O)OR a , -OC(O)N(R a )2, -C(O)N(R a )2, -N(R a )C(O)OR a , -N(R a )C(O)R a , -N(R a )C(O)N(R a )2, -N(R a )C(NR a )N(R a )2, -N(R a )S(O) t N(R a )2 (wherein t is 1 or 2), -P(=O)(R a )(Ra ), or -OP(=O)(OR a )2, wherein each R a are independently hydrogen, alkyl, haloalkyl, carbocyclyl, carbocyclylalkyl, aryl, aralkyl, heterocycloalkyl, heterocycloalkylalkyl, heteroaryl, or heteroarylalkyl, each of which moieties (other than hydrogen) is optionally substituted with one or more substituents (up to six, valences allowed) independently selected from OH, NH2, oxo, halo, nitro, COOH, C(O)NH2, or cyano. For example, a cycloalkyl substituent can have a halide substituted at one or more ring carbons, etc. Protecting groups that can form the protective derivatives of the above substituents are known to those of skill in the art and can be found in references such as Greene and Wuts, above.

[0072] Suitable substituents include haloalkyl and trihaloalkyl, alkoxyalkyl, halophenyl, -M-heteroaryl, -M-heterocycle, -M-aryl, -M-OR a , -M-SR a , -MN(R a )2, -M-OC(O)N(R a )2, -MC(=NR a )N(R a )2, -MC(=NR a ) OR a , -MP(O)(R a )2, Si(R a )3, -M-NR a C(O)R a , -M-NR a C(O)OR a , -MC(O)R a , -MC(=S)R a , -MC(=S)NR a R a , -MC(O)N(R a )2, -MC(O)NR a -MN(R a )2, -M-NR a C(NR a )N(Ra )2, -M-NR a C(S)N(R a )2, -MS(O)2R a , -MC(O)R a , -M-OC(O)R a , -MC(O)SR a , -MS(O)2N(R a )2, -C(O)-MC(O)R a , -MCO2R a , -MC(=O)N(R a )2, -MC(=NH)N(R a )2, and -M-OC(=NH)N(R a )2 (wherein M is C 1~6 and the like. Examples of the alkyl group include, but are not limited to, aryl, aryl, and alkyl groups.

[0073] When a ring system (e.g., cycloalkyl, heterocyclyl, aryl, or heteroaryl) is substituted with several substituents varying within an explicitly defined range, it is understood that the total number of substituents does not exceed the normally available valences under the existing pathology. Thus, for example, a phenyl ring substituted with a "p" substituent (where "p" ranges from 0 to 5) may have 0 to 5 substituents, while a pyridinyl ring substituted with a "p" substituent is understood to have several substituents ranging from 0 to 4. The maximum number of substituents that a group in the disclosed compounds may have can be easily determined. Substituted groups include only those combinations of substituents and variables that result in a stable or chemically feasible compound. A stable or chemically feasible compound is one that has sufficient stability to permit its preparation and detection, among other factors. In some embodiments, the disclosed compounds are sufficiently stable that when maintained at a temperature of 40° C. or less in the absence of moisture (e.g., less than about 10%, less than about 5%, less than about 2%, less than about 1%, or less than about 0.5%) or other chemically reactive conditions, they remain substantially unchanged for, e.g., at least about 3 days, at least about 1 week, at least about 2 weeks, at least about 4 weeks, or at least about 6 weeks.

[0074] The terms "combining, combining, to combine, combining" refer to the act of adding at least one chemical to another chemical(s), either sequentially or simultaneously. In some embodiments, bringing these chemicals together can result in the conversion of the first chemical to one or more different chemicals. This conversion can occur through one or more chemical reactions, such as, for example, covalent bonds being formed, broken, rearranged, etc. A non-limiting example can include hydrolysis of an ester to an alcohol and a carboxylic acid, which can result from combining an ester with a suitable base. In another non-limiting example, an aryl fluoride can be combined with an amine to provide an aryl amine through a substitution process. These terms also include changes associated with the generation of charged chemicals and charged chemicals, such as, but not limited to, N-oxide formation, acid addition salt formation, base addition salt formation, etc. These terms include the generation and / or conversion of radical chemicals and isotopically labeled chemicals.

[0075] The terms "convert, converting, to convert, convert" refer to a subset of "combining" and its grammatical equivalents, where the action of one or more reagents converts one or more functional groups on a chemical to another functional group(s). For example, converting includes, but is not limited to, converting a nitro functional group on a chemical to an amine using a reducing agent. Converting also includes alterations of charged chemicals, radical chemicals, and isotopically labeled chemicals. However, the term "convert" does not include alterations of conserved bonds in the disclosed genera and compounds.
