Description

[Technical Field]

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims priority to and benefit of U.S. Provisional Patent Application No. 62 / 934,293, filed November 12, 2019, which is incorporated herein by reference in its entirety. [Background technology]

[0002] background Cystic fibrosis (CF), an autosomal recessive disease, is caused by dysfunction of the cAMP-activated plasma membrane chloride channel, the cystic fibrosis transmembrane conductance regulator (CFTR), which can cause damage to the lungs, pancreas, and other organs. The gene encoding CFTR has been identified and sequenced (see Gregory, RJ et al. (1990) Nature 347:382-386 (Non-Patent Document 1); Rich, DP et al. (1990) Nature 347:358-362 (Non-Patent Document 2); Riordan, JR et al. (1989) Science 245:1066-1073 (Non-Patent Document 3)). CFTR, a member of the ATP-binding cassette (ABC) superfamily, consists of two six-transmembrane domains (MSD1 and MSD2), two nucleotide-binding domains (NBD1 and NBD2), a regulatory region (R), and four cytoplasmic loops (CL1-CL4). Normally, the CFTR protein is located primarily in the apical membrane of epithelial cells, where it functions to conduct anions, including chloride, carbonate, and thiocyanate, into and out of the cell. CFTR may have a regulatory role over other electrolyte channels, including the epithelial sodium channel ENaC.

[0003] In patients with cystic fibrosis, the absence or dysfunction of CFTR leads to exocrine dysfunction and multisystem disease characterized by pancreatic insufficiency and malabsorption, as well as abnormal mucociliary clearance in the lungs, mucus congestion, chronic pulmonary infection and inflammation, decreased lung function, and ultimately respiratory failure.

[0004] Although over 1,900 mutations have been identified in the CFTR gene, detailed understanding of how each CFTR mutation may affect channel function is only known for a subset of mutations (Derichs, European Respiratory Review, 22:127, 58-65 (2013)). The most frequent CFTR mutation is an in-frame deletion of phenylalanine (ΔF508) at residue 508 in the first nucleotide-binding domain (NBD1). More than 80% of cystic fibrosis patients have a deletion at residue 508 in at least one allele. The loss of this critical phenylalanine renders the CFTR NBD1 domain conformationally unstable at physiological temperatures, compromising the integrity of the interdomain interface between NBD1 and the second transmembrane domain (ICL4) of CFTR. The ΔF508 mutation leads to the production of misfolded CFTR protein, which does not transport to the plasma membrane but instead is retained in the endoplasmic reticulum and targeted for degradation by the ubiquitin-proteasome system.

[0005] Loss of functional CFTR channels in the plasma membrane disrupts ion homeostasis and airway surface hydration, leading to decreased lung function. Decreased periciliary fluid volume and increased mucus viscosity impede mucociliary clearance, leading to chronic infection and inflammation. In the lung, loss of CFTR function causes numerous physiological effects downstream of altered anion conductance, leading to dysfunction of additional organs such as the pancreas, intestine, and gallbladder.

[0006] Guided in part by research into the mechanistic aspects of CFTR misfolding and dysfunction, small molecule CFTR modulators have been identified that can increase CFTR channel function. Despite the identification of compounds that modulate CFTR, there is no cure for this deadly disease, and there is a need for the identification of new compounds and new therapeutic methods, as well as new methods for treating or reducing the severity of cystic fibrosis and other CFTR-mediated conditions and diseases in patients.

Rieger et al. (eds.), Springer Verlag (1991), and Hale & Marham, The Harper Collins Dictionary of Biology (1991). As used herein, the following terms have the meanings ascribed to them below, unless otherwise specified.

[0091] In this disclosure, the words "comprises," "comprising," "containing," and "having" and the like may have the meaning ascribed to them in U.S. patent law, and may mean "includes," "including," and the like, and the terms "consisting essentially of" or "consisting essentially of" similarly have the meaning ascribed to them in U.S. patent law, and these terms are open-ended and permit the presence of more than what is recited, but exclude prior art embodiments, so long as the basic or novel characteristics of the recited thing are not changed by the presence of more than what is recited.

[0092] As used herein, the term "or" is understood to be inclusive unless specifically stated otherwise or clear from context. As used herein, the terms "a," "an," and "the" are understood to be singular or plural unless specifically stated otherwise or clear from context.

[0093] The term "acyl" is art-recognized and refers to a group represented by the general formula hydrocarbylC(O)-, preferably alkylC(O)-.

[0094] The term "acylamino" is art-recognized and refers to an amino group substituted with an acyl group and may be represented, for example, by the formula hydrocarbylC(O)NH-.

[0095] The term "acyloxy" is art-recognized and refers to a group represented by the general formula hydrocarbylC(O)O-, preferably alkylC(O)O-.

[0096] The term "alkoxy" refers to an alkyl group, preferably a lower alkyl group, having an oxygen attached thereto. Representative alkoxy groups include methoxy, ethoxy, propoxy, tert-butoxy, and the like.

[0097] The term "alkoxyalkyl" refers to an alkyl group substituted with an alkoxy group and may be represented by the general formula alkyl-O-alkyl.

[0098] As used herein, the term "alkenyl" refers to an aliphatic group containing at least one double bond and is intended to include both "unsubstituted alkenyl" and "substituted alkenyl," the latter of which refers to an alkenyl moiety having substituents replacing hydrogen on one or more carbons of the alkenyl group. Such substituents may occur on one or more carbons included or not included in one or more double bonds. Furthermore, such substituents include all of those contemplated for alkyl groups, as discussed below, except where stability would be inhibited. For example, substitution of alkenyl groups with one or more alkyl, carbocyclyl, aryl, heterocyclyl, or heteroaryl groups is contemplated.

[0099] An "alkyl" group or "alkane" is a fully saturated, straight-chain or branched non-aromatic hydrocarbon. Typically, a straight-chain or branched alkyl group, unless otherwise defined, has 1 to about 20 carbon atoms, preferably 1 to about 10, and more preferably 1 to 6. Examples of straight-chain and branched alkyl groups include methyl, ethyl, n-propyl, iso-propyl, n-butyl, sec-butyl, tert-butyl, pentyl, hexyl, pentyl, and octyl. C1-C6 straight-chain or branched alkyl groups are also referred to as "lower alkyl" groups.

[0100] Furthermore, the term "alkyl" (or "lower alkyl"), as used throughout the specification, examples, and claims, is intended to include both "unsubstituted alkyl" and "substituted alkyl," the latter of which refers to an alkyl moiety having substituents replacing hydrogen on one or more carbons of the hydrocarbon backbone. Such substituents, unless otherwise specified, can include, for example, halogen, hydroxyl, carbonyl (such as carboxyl, alkoxycarbonyl, formyl, or acyl), thiocarbonyl (such as thioester, thioacetate, or thioformate), alkoxy, phosphoryl, phosphate, phosphonate, phosphinate, amino, amido, amidine, imine, cyano, nitro, azido, sulfhydryl, alkylthio, sulfate, sulfonate, sulfamoyl, sulfonamido, sulfonyl, heterocyclyl, aralkyl, or aromatic or heteroaromatic moieties. It will be understood by those skilled in the art that the moieties substituted on the hydrocarbon chain can themselves be substituted, where appropriate. For example, substituents of substituted alkyls can include substituted and unsubstituted forms of amino, azido, imino, amido, phosphoryl (including phosphonates and phosphinates), sulfonyl (including sulfates, sulfonamides, sulfamoyl, and sulfonates), and silyl groups, as well as ethers, alkylthio, carbonyl (including ketones, aldehydes, carboxylates, and esters), -CF3, -CN, and the like. Exemplary substituted alkyls are described below. Cycloalkyls can be further substituted with alkyls, alkenyls, alkoxys, alkylthios, aminoalkyls, carbonyl-substituted alkyls, -CF3, -CN, and the like.

[0101] "C x-y The term " when used in conjunction with a chemical moiety such as acyl, acyloxy, alkyl, alkenyl, alkynyl, or alkoxy, is meant to include groups containing x to y carbons in the chain. For example, "C x-yThe term "alkyl" refers to substituted or unsubstituted saturated hydrocarbon groups, including straight-chain alkyl and branched-chain alkyl groups containing x to y carbons in the chain, including haloalkyl groups such as trifluoromethyl and 2,2,2-trifluoroethyl. C0 alkyl represents a hydrogen when the group is in a terminal position and a bond when the group is internal. 2-y alkenyl" and "C 2-y The term "alkynyl" refers to substituted or unsubstituted unsaturated aliphatic groups analogous in length and possible substitution to the alkyls described above, but which contain at least one double or triple bond respectively.

[0102] The term "alkylamino," as used herein, refers to an amino group substituted with at least one alkyl group.

[0103] The term "alkylthio," as used herein, refers to a thiol group substituted with an alkyl group and may be represented by the general formula alkylS-.

[0104] The term "haloalkyl," as used herein, refers to an alkyl group in which at least one hydrogen has been replaced with a halogen, such as fluoro, chloro, bromo, or iodo. Exemplary haloalkyl groups include trifluoromethyl, difluoromethyl, fluoromethyl, 2-fluoroethyl, 2,2-difluoroethyl, and 2,2,2-trifluoroethyl.

[0105] The term "alkynyl," as used herein, refers to an aliphatic group containing at least one triple bond and is intended to include both "unsubstituted alkynyl" and "substituted alkynyl," the latter of which refers to an alkynyl moiety having substituents replacing hydrogen on one or more carbons of the alkynyl group. Such substituents may occur on one or more carbons included or not included in one or more triple bonds. Furthermore, such substituents include all of those contemplated for alkyl groups, as discussed above, except where stability would be inhibited. For example, substitution of alkynyl groups with one or more alkyl, carbocyclyl, aryl, heterocyclyl, or heteroaryl groups is contemplated.

[0106] The term "amide" as used herein means TIFF2025160375000304.tif19128, where each R 10 independently represent hydrogen or a hydrocarbyl group, or two R 10 together with the N atom to which they are attached complete a heterocycle with 4 to 8 atoms in the ring structure.

[0134] The term "silyl" refers to a silicon moiety having three hydrocarbyl moieties attached thereto.

[0135] The term "substituted" refers to a moiety having a substituent in place of a hydrogen on one or more carbon atoms of the backbone. It is understood that "substituted" or "substituted with" includes the implicit proviso that such substitution results in a stable compound, e.g., a stable compound that does not spontaneously undergo transformation by, for example, rearrangement, cyclization, elimination, and the like, subject to the permissible valences of the substituted atom and substituent. As used herein, the term "substituted" is intended 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 nonaromatic substituents of organic compounds.

[0146] The present invention also encompasses various isomers and mixtures thereof. Certain compounds of the present invention may exist in various stereoisomeric forms. Stereoisomers are compounds that differ only in their spatial configuration. Enantiomers are pairs of stereoisomers whose mirror images are not superimposable, most commonly because they contain an asymmetrically substituted carbon atom that serves as a chiral center. "Enantiomer" refers to one of a pair of molecules that are mirror images of each other and are not superimposable. Diastereomers are stereoisomers that are not related as mirror images, most commonly because they contain two or more asymmetrically substituted carbon atoms. "R" and "S" refer to the configuration of substituents around one or more chiral carbon atoms. If a chiral center is not defined as R or S, either a pure enantiomer or a mixture of both configurations exists.

[0147] "Racemate" or "racemic mixture" refers to a compound of equimolar amounts of two enantiomers, and such mixtures do not exhibit optical activity, i.e., they do not rotate the plane of polarized light. In certain embodiments, the compounds of the present invention may be racemic.

[0148] In certain embodiments, the compounds of the present invention can be enriched with one enantiomer.For example, the compounds of the present invention can have an enantiomeric excess of more than about 30%, an enantiomeric excess of more than about 40%, an enantiomeric excess of more than about 50%, an enantiomeric excess of more than about 60%, an enantiomeric excess of more than about 70%, an enantiomeric excess of more than about 80%, an enantiomeric excess of more than about 90%, or even an enantiomeric excess of more than about 95%.In certain embodiments, the compounds of the present invention can have two or more stereocenters.In certain such embodiments, the compounds of the present invention can be enriched with one or more diastereomers. For example, compounds of the present invention may have a diastereomeric excess of greater than about 30%, greater than about 40%, greater than about 50%, greater than about 60%, greater than about 70%, greater than about 80%, greater than about 90%, or even a diastereomeric excess of about 95% or greater.

[0149] In certain embodiments, therapeutic preparations can be enriched to provide primarily one enantiomer of a compound (e.g., of Formula (I)). An enantiomerically enriched mixture can contain, for example, at least about 60 mole percent of one enantiomer, or more preferably at least about 75, about 90, about 95, or even about 99 mole percent of one enantiomer. In certain embodiments, a compound enriched in one enantiomer is substantially free of the other enantiomer, where substantially free means that the substance in question accounts for, for example, less than about 10%, or less than about 5%, or less than about 4%, or less than about 3%, or less than about 2%, or less than about 1%, relative to the amount of the other enantiomer in the composition or compound mixture. For example, if a composition or compound mixture contains about 98 grams of a first enantiomer and about 2 grams of a second enantiomer, it would be said to contain about 98 mole percent of the first enantiomer and only about 2% of the second enantiomer.

[0150] In certain embodiments, therapeutic preparations can be enriched to provide predominantly one diastereomer of a compound (e.g., of Formula (I)). A diastereomerically enriched mixture can contain, for example, at least about 60 mole percent, or more preferably at least about 75, about 90, about 95, or even about 99 mole percent of one diastereomer.

[0151] The compounds of the present invention can be prepared as individual isomers either by isomer-specific synthesis or resolved from an isomeric mixture. Conventional resolution techniques include using an optically active acid to form a salt of the free base of each isomer of the isomeric pair (followed by fractional crystallization and regeneration of the free base), using an optically active amine to form a salt of the acid form of each isomer of the isomeric pair (followed by fractional crystallization and regeneration of the free acid), using an optically pure acid, amine, or alcohol to form an ester or amide of each isomer of the isomeric pair (followed by chromatographic separation and removal of the chiral auxiliary), or resolving an isomeric mixture of either the starting material or the final product using various well-known chromatographic methods. When the stereochemistry of a disclosed compound is named or depicted by structure, the named or depicted stereoisomer is at least about 60%, 70%, 80%, 90%, 99%, or 99.9% pure by weight relative to other stereoisomers. When a single enantiomer is named or depicted by structure, the depicted or named enantiomer is at least about 60%, about 70%, about 80%, about 90%, about 99%, or about 99.9% by weight optically pure. Percent optical purity by weight is the ratio of the weight of the enantiomer present divided by the total weight of the enantiomers present and the weight of that optical isomer.

[0152] In the pictorial representations of compounds given throughout this application, thick tapered lines TIFF2025160375000309.tif5128 indicates substituents above the plane of the ring to which the asymmetric carbon belongs, and dotted lines TIFF2025160375000310.tif5128 shows substituents below the plane of the ring to which the asymmetric carbon belongs.

[0153] As used herein, the compounds of the present invention may be in the form of one of the possible isomers, rotamers, atropisomers, tautomers, or mixtures thereof, for example, as substantially pure geometric (cis or trans) isomers, diastereomers, optical isomers (enantiomers), racemates, or mixtures thereof.

[0154] Isotopically labeled forms of the disclosed compounds have one or more atoms of the compound replaced with one or more atoms having an atomic mass or mass number different from that normally occurring in greater natural abundance. Examples of isotopes that are readily commercially available and can be incorporated into the disclosed compounds by well-known methods include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphate, fluorine, and chlorine, such as 2H, 3H, 13C, 14C, 15N, 18O, 17O, 31P, 32P, 35S, 18F, and 36Cl, respectively. The isotopically labeled compounds provided herein can generally be prepared by carrying out the procedures disclosed herein, substituting isotopically labeled reactants for non-isotopically labeled reactants.

[0155] The concentration of such a heavier isotope, specifically deuterium, can be defined by the isotopic enrichment factor. As used herein, the term "isotopic enrichment factor" means the ratio between the isotopic abundance and the natural abundance of a specified isotope. When hydrogen atoms in compounds of the invention are replaced with deuterium, such compounds have an isotopic enrichment factor, per designated deuterium, of at least 3500 (52.5% deuterium incorporation at each designated deuterium atom), at least 4000 (60% deuterium incorporation), at least 4500 (67.5% deuterium incorporation), at least 5000 (75% deuterium incorporation), at least 5500 (82.5% deuterium incorporation), at least 6000 (90% deuterium incorporation), at least 6333.3 (95% deuterium incorporation), at least 6466.7 (97% deuterium incorporation), at least 6600 (99% deuterium incorporation), or at least 6633.3 (99.5% deuterium incorporation).

[0156] The isotopically labeled compounds provided herein can be used in many beneficial ways. Compounds incorporating 14C are suitable for drug and / or substrate tissue distribution assays. Tritium (3H) and carbon-14 (14C) are preferred isotopes due to their ease of preparation and excellent detectability. Heavier isotopes, such as deuterium (2H), have therapeutic advantages due to their greater metabolic stability. Metabolism undergoes a first-order kinetic isotope effect, with heavier isotopes having lower ground states, resulting in reduced rate-limiting bond ruptures. Slowing metabolism may result in increased in vivo half-life, reduced dosage requirements, or improved therapeutic index.

[0157] For further discussion, see S.L. Harbeson and R.D. Tung, Deuterium in Drug Discovery and Development, Ann. Rep. Med. Chem. 2011, 46, 403-417; Foster, A.B., "Deuterium Isotope Effects in Studies of Drug Metabolism," Trends in Pharmacological Sciences, 5:524-527 (1984); and Foster, A.B., "Deuterium Isotope Effects in the Metabolism of Drugs and Xenobiotics: Implications for Drug Design," Advances in Drug Research, 14:1-40 (1985).

[0158] Metabolic stability can be affected by the processing of a compound in various organs of the body. For example, compounds with poor pharmacokinetic profiles are prone to oxidative metabolism. Currently available in vitro liver microsome assays provide valuable information on the course of this type of oxidative metabolism, which in turn aids in the rational design of deuterated compounds as disclosed herein. Improvements can be measured in several assays known in the art, such as in vivo half-life (t), the concentration at maximum therapeutic effect (C), the area under the dose-response curve (AUC), and bioavailability, as well as in terms of increased clearance, reduced dose, and reduced material costs.

[0159] Another effect of deuterated compounds can be the reduction or elimination of undesired toxic metabolites. For example, if a toxic metabolite is produced through oxidative carbon-hydrogen (CH) bond cleavage, the deuterated analog will have a slower reaction time, slowing the production of the undesired metabolite, even if the specific oxidation is not the rate-limiting step. See, e.g., Hanzlik et al., J. Org. Chem. 55, 3992-3997, 1990; Reider et al., J. Org. Chem. 52, 3326-3334, 1987; Foster, Adv. Drug Res. 14, 1-40, 1985; Gillette et al., Biochemistry 33(10) 2927-2937, 1994; and Jarman et al., Carcinogenesis 16(4), 683-688, 1993.

[0160] The term "subject" to which administration is contemplated includes, but is not limited to, humans (i.e., male or female of any age, e.g., a pediatric subject (e.g., infant, child, adolescent) or an adult subject (e.g., young adult, middle-aged adult, or elderly adult)) and / or another primate (e.g., cynomolgus monkey, rhesus monkey), 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. A preferred subject is a human.

[0161] As used herein, a therapeutic agent that "prevents" a disorder or condition refers to a compound that, in a statistical sample, reduces or delays the occurrence of the disorder or condition in a treated sample relative to an untreated control sample, or reduces the severity of one or more symptoms of the disorder or condition relative to an untreated control sample.

[0162] The term "treating" means reducing, inhibiting, attenuating, curtailing, arresting, or stabilizing the onset or progression of a disease (e.g., a disease or disorder described herein), reducing the severity of the disease, or ameliorating the symptoms associated with the disease. Treatment includes treating the symptoms of a disease, disorder, or condition. Without being bound by any theory, in some embodiments, treatment involves enhancing defective CFTR activity. When administered before the clinical manifestation of an undesired condition (e.g., a disease or other undesired condition in a subject), treatment is prophylactic (i.e., protects the subject from developing the undesired condition), whereas when administered after the onset of symptoms of the undesired condition, treatment is therapeutic (i.e., intended to reduce, ameliorate, or stabilize an existing undesired condition or its side effects).

[0163] As used herein, the term "prodrug" refers to a pharmacological derivative of a parent drug molecule that requires either spontaneous or enzymatic biotransformation in an organism to release the active drug. For example, a prodrug is a variant or derivative of a compound of the present invention that has groups that are cleavable under certain metabolic conditions, resulting in a compound of the present invention upon cleavage. As a result, such prodrugs are pharmaceutically active in vivo when they undergo solvolysis under physiological conditions or enzymatic degradation. Prodrug compounds herein may be referred to as single, double, triple, etc., depending on the number of biotransformation steps required to release the active drug in an organism and the number of functional groups present in the precursor form. Prodrug forms often offer advantages of solubility, tissue compatibility, or delayed release in mammalian organisms (see Bundgard, Design of Prodrugs, pp. 7-9, 21-24, Elsevier, Amsterdam 1985, and Silverman, The Organic Chemistry of Drug Design and Drug Action, pp. 352-401, Academic Press, San Diego, CA, 1992). Prodrugs generally known in the art include well-known acid derivatives, such as esters prepared by reacting the parent acid with a suitable alcohol, amides prepared by reacting the parent acid compound with an amine, and basic groups reacted to form acylated base derivatives. Of course, other prodrug derivatives can be combined with other features disclosed herein to enhance bioavailability.

[0164] Thus, those skilled in the art will understand that certain compounds of the present disclosure having free amino, amide, hydroxy, or carboxylic acid groups can be converted into prodrugs. Prodrugs include compounds having an amino acid residue or a polypeptide chain of two or more (e.g., 2, 3, or 4) amino acid residues covalently attached via peptide bonds to a free amino, hydroxy, or carboxylic acid group of a compound of the present disclosure. Amino acid residues include the 20 naturally occurring amino acids, commonly designated by their three-letter symbols, and also include 4-hydroxyproline, hydroxylysine, desmosine, isodesmosine, 3-methylhistidine, norvaline, β-alanine, gamma-aminobutyric acid, citrulline homocysteine, homoserine, ornithine, and methionine sulfone. Prodrugs also include compounds having a carbonate, carbamate, amide, or alkyl ester moiety covalently attached to any of the above substituents disclosed herein.

[0165] As used herein, "therapeutically effective amount" refers to an amount sufficient to achieve a desired therapeutic effect. For example, a therapeutically effective amount can refer to an amount sufficient to ameliorate at least one sign or symptom of cystic fibrosis.

[0166] A "response" to a treatment method can include, among other things, a decrease or amelioration of negative symptoms, a decrease in the progression of the disease or its symptoms, an increase in beneficial symptoms or clinical outcomes, a reduction in side effects, stabilization of the disease, partial or complete relief of the disease, etc.

[0167] As used herein, "CFTR" refers to the cystic fibrosis transmembrane conductance regulator. Defects in the function of the CFTR ion channel result from loss-of-function mutations in CFTR. Such mutations cause exocrine dysfunction, abnormal mucociliary clearance, and lead to cystic fibrosis. The most common CFTR mutation in cystic fibrosis (CF) patients results in a specific deletion of three nucleotides in the codon for phenylalanine at position 508. This mutation, known as "ΔF508," is found in approximately 70% of CF patients worldwide. The ΔF508 mutation reduces the stability of the CFTR NBD1 domain and limits CFTR interdomain assembly. Because CF is an autosomal recessive disease, CF patients carrying the ΔF508 CFTR mutation must also carry a second defective copy of CFTR. Approximately 2,000 different CF-causing CFTR mutations have been identified in CF patients. A CF patient with a ΔF508 CFTR mutation can be homozygous for that mutation (ΔF508 / ΔF508). A CF patient can also be ΔF508 heterozygous if the second CFTR allele carried by such a patient contains a different CFTR loss-of-function mutation instead. Such CFTR mutations include, but are not limited to, G542X, G551D, N1303K, W1282X, R553X, R117H, R1162X, R347P, G85E, R560T, A455E, ΔI507, G178R, S549N, S549R, G551S, G970R, G1244E, S1251N, S1255P, and G1349D.

[0168] As used herein, the term "CFTR modulator" refers to a compound that increases the activity of CFTR. In certain embodiments, a CFTR modulator is a CFTR corrector or a CFTR potentiator, or a dual-acting compound with corrector and potentiator activity. These dual-acting agents are useful when mutations result in the absence or reduced amount of synthetic CFTR protein.

[0169] As used herein, the term "CFTR corrector" refers to a compound that increases the amount of functional CFTR protein on the cell surface, thus enhancing ion transport through CFTR. CFTR correctors partially "rescue" misfolding of the CFTR protein, particularly misfolding resulting from mutations within CFTR, thereby allowing CFTR to mature and functionally express on the cell surface. CFTR correctors may alter the folding environment of a cell in a way that promotes CFTR folding, and may include compounds that directly interact with the CFTR protein to alter its folding, conformational maturation, or stability. Examples of correctors include, but are not limited to, VX-809, VX-661, VX-152, VX-440, VX-445, VX-659, VX-121, VX-983, compounds described in US2019 / 0248809A1, GLPG2222, GLPG2737, GLPG3221, GLPG2851, FDL169, FDL304, FDL2052160, FD2035659, and PTI-801.

[0170] As used herein, the term "CFTR potentiator" refers to a compound that increases the ion channel activity of the CFTR protein located on the cell surface and enhances ion transport. CFTR potentiators restore defective channel function resulting from CFTR mutations or otherwise increase the activity of CFTR on the cell surface. Examples of potentiators include, but are not limited to, ivacaftor (VX770), deuterated ivacaftor (CPT656, VX-561), PTI-808, QBW251, GLPG1837, GLPG2451, ABBV-3067, ABBV-974, ABBV-191, FDL176, and genistein.

[0171] As used herein, "CFTR disease or condition" refers to a disease or condition associated with a defect in CFTR activity, such as cystic fibrosis, congenital bilateral absence of the vas deferens (CBAVD), acute, recurrent, or chronic pancreatitis, disseminated bronchiectasis, asthma, allergic pulmonary aspergillosis, smoking-related lung diseases such as chronic obstructive pulmonary disease (COPD), rhinosinusitis, congenital pneumonia, intestinal malabsorption, celiac disease, nasal polyposis, nontuberculous mycobacteriosis, pancreatic steatorrhea, intestinal atresia, dry eye disease, protein C deficiency, abetalipoproteinemia, lysosomal storage diseases, type 1 chylomyocarditis, mild lung disease, lipid processing deficiency, hereditary angioedema type 1, coagulation-fibrinolysis, hereditary hemochromatosis, CFTR-related metabolic syndrome, chronic bronchitis, constipation, pancreatic insufficiency, hereditary emphysema, and Sjogren's syndrome.

[0192] Pharmaceutical Compositions The compositions and methods of the present invention can be used to treat subjects in need of treatment. In certain embodiments, the subject is a mammal, such as a human, or a non-human mammal. When administered to a subject, such as a human, the composition or compound is preferably administered as a pharmaceutical composition, e.g., comprising a compound of the present invention and a pharmaceutically acceptable carrier. Pharmaceutically acceptable carriers are well known in the art and include, for example, aqueous solutions such as water or physiologically buffered saline, or other solvents or vehicles such as glycols, glycerol, oils such as olive oil, or injectable organic esters. In preferred embodiments, when such pharmaceutical compositions are intended for human administration, particularly for invasive routes of administration (i.e., routes such as injection or implantation that avoid transport or diffusion through epithelial barriers), the aqueous solutions are pyrogen-free or substantially pyrogen-free. Excipients can be selected, for example, to provide delayed release of the drug or to selectively target one or more cells, tissues, or organs. Pharmaceutical compositions can be in unit dosage form, such as tablets, capsules (including sprinkle capsules and gelatin capsules), granules, lyophilized forms for reconstitution, powders, solutions, syrups, suppositories, infusions, etc. The composition may also be present in a transdermal delivery system, for example, a skin patch.The composition may also be present in a solution suitable for topical administration, such as eye drops.

[0193] Pharmaceutically acceptable carriers can contain physiologically acceptable agents that, for example, stabilize, increase the solubility, or enhance the absorption of a compound, such as a compound of the present invention. Such physiologically acceptable agents include, for example, carbohydrates such as glucose, sucrose, or dextran; antioxidants such as ascorbic acid or glutathione; chelating agents; low-molecular-weight proteins; or other stabilizers or excipients. The choice of a pharmaceutically acceptable carrier containing a physiologically acceptable agent depends, for example, on the route of administration of the composition. The preparation or pharmaceutical composition can be a self-emulsifying or self-microemulsifying drug delivery system. The pharmaceutical composition (preparation) can also be a liposome or other polymer matrix, into which, for example, a compound of the present invention can be incorporated. For example, liposomes containing phospholipids or other lipids are non-toxic, physiologically acceptable, and metabolizable carriers that are relatively easy to prepare and administer.

[0194] As used herein, the phrase "pharmaceutically acceptable" refers to compounds, materials, compositions and / or dosage forms that are suitable for use in contact with the tissues of a subject without undue toxicity, irritation, allergic response, or other problem or complication, and that are within the scope of sound medical judgment and commensurate with a reasonable benefit / risk ratio.

[0195] As used herein, the phrase "pharmaceutically acceptable carrier" refers to a pharmaceutically acceptable material, composition, or vehicle, such as a liquid or solid filler, diluent, excipient, solvent, or encapsulating material. Each carrier must be "acceptable" in the sense of being compatible with the other ingredients of the formulation and not harmful to the subject. Examples of materials that can function as pharmaceutically acceptable carriers include: (1) sugars, such as lactose, glucose, and sucrose; (2) starches, such as corn starch and potato starch; (3) celluloses and their derivatives, such as sodium carboxymethylcellulose, ethylcellulose, and cellulose acetate; (4) powdered tragacanth; (5) malt; (6) gelatin; (7) talc; (8) excipients, such as cocoa butter and suppository wax; and (9) peanut oil, cottonseed oil, safflower oil, sesame oil, olive oil, corn oil, and soybean oil. (10) glycols such as propylene glycol, (11) polyols such as glycerin, sorbitol, mannitol, and polyethylene glycol, (12) esters such as ethyl oleate and ethyl laurate, (13) agar, (14) buffers such as magnesium hydroxide and aluminum hydroxide, (15) alginic acid, (16) pyrogen-free water, (17) isotonic saline, (18) Ringer's solution, (19) ethyl alcohol, (20) phosphate buffer solution, and (21) other non-toxic, compatible substances used in pharmaceutical formulations.

[0196] Pharmaceutical compositions (preparations) can be administered to a subject by any of a number of routes of administration, including, for example, orally (e.g., as drenches such as aqueous or non-aqueous solutions or suspensions, tablets, capsules (including sprinkle capsules and gelatin capsules), boluses, powders, granules, or pastes for application to the tongue), absorption through the oral mucosa (e.g., sublingually), anally, rectally, or vaginally (e.g., as pessaries, creams, or foams), parenterally (e.g., as sterile solutions or suspensions, including intramuscularly, intravenously, subcutaneously, or intrathecally), nasally, intraperitoneally, subcutaneously, transdermally (e.g., as a patch applied to the skin), and topically (e.g., as a cream, ointment, or spray applied to the skin, or as eye drops). The compounds may also be formulated for inhalation. In certain embodiments, the compounds may simply be dissolved or suspended in sterile water. Details of suitable routes of administration and compositions suitable therefor can be found, for example, in U.S. Pat. Nos. 6,110,973, 5,763,493, 5,731,000, 5,541,231, 5,427,798, 5,358,970, and 4,172,896, as well as patents cited therein.

[0197] The formulations can be conveniently provided in unit dosage form and can be prepared by any method well known in the art of pharmacy. The amount of active ingredient that can be combined with a carrier material to produce a single dosage form will vary depending on the subject being treated and the particular mode of administration. The amount of active ingredient that can be combined with a carrier material to produce a single dosage form will generally be that amount of the compound that produces a therapeutic effect. Generally, out of 100 percent, this amount will range from about 1 percent to about 99 percent of the active ingredient, preferably from about 5 percent to about 70 percent, and most preferably from about 10 percent to about 30 percent.

[0198] Methods of preparing these formulations or compositions include the step of bringing into association an active compound, such as a compound of the present invention, with the carrier and, optionally, one or more accessory ingredients. In general, the formulations are prepared by uniformly and intimately bringing into association a compound of the present invention with liquid carriers, or finely divided solid carriers, or both, and then, if necessary, shaping the product.

[0199] Formulations of the present invention suitable for oral administration may be in the form of capsules (including sprinkle capsules and gelatin capsules), cachets, pills, tablets, lozenges (using a flavored base, usually sucrose and acacia or tragacanth), lyophiles, powders, granules, or as a solution or suspension in an aqueous or non-aqueous liquid, or an oil-in-water or water-in-oil liquid emulsion, or an elixir or syrup, or pastille (using an inert base such as gelatin and glycerin, or sucrose and acacia), and / or mouthwash, each containing a predetermined amount of a compound of the present invention as an active ingredient. The compounds of the present invention may also be administered as a bolus, electuary, or paste.

[0200] To prepare solid dosage forms for oral administration (such as capsules (including sprinkle capsules and gelatin capsules), tablets, pills, dragees, powders, granules, etc.), the active ingredient is mixed with one or more pharmaceutically acceptable carriers, such as sodium citrate or dicalcium phosphate, and / or any of the following: (1) fillers or extenders, such as starch, lactose, sucrose, glucose, mannitol, and / or silicic acid; (2) binders, such as carboxymethylcellulose, alginates, gelatin, polyvinylpyrrolidone, sucrose, and / or acacia; (3) humectants, such as glycerol; and (4) disintegrating agents. Ingredients that may be used include, for example, agar-agar, calcium carbonate, potato or tapioca starch, alginic acid, certain silicates, and sodium carbonate, (5) solution retardants, for example, paraffin, (6) absorption accelerators, for example, quaternary ammonium compounds, (7) wetting agents, for example, cetyl alcohol and glycerol monostearate, (8) absorbents, for example, kaolin and bentonite clay, (9) lubricants, for example, talc, calcium stearate, magnesium stearate, solid polyethylene glycol, sodium lauryl sulfate, and mixtures thereof, (10) complexing agents such as modified and unmodified cyclodextrins, and (11) coloring agents. For capsules (including sprinkle capsules and gelatin capsules), tablets, and pills, the pharmaceutical compositions may also contain buffering agents. Solid compositions of a similar type may also be employed as fillers in soft and hard-filled gelatin capsules using lactose or milk sugar, high molecular weight polyethylene glycols, and similar excipients.

[0201] Tablets can be made by compression or molding, optionally with one or more accessory ingredients. Compressed tablets can be prepared using binders (e.g., gelatin or hydroxypropylmethylcellulose), lubricants, inert diluents, preservatives, disintegrants (e.g., sodium starch glycolate or cross-linked sodium carboxymethylcellulose), surfactants, or dispersants. Molded tablets can be made by molding a mixture of the powdered compound moistened with an inert liquid diluent in a suitable machine.

[0202] Tablets and other solid dosage forms of pharmaceutical compositions, such as dragees, capsules (including sprinkle capsules and gelatin capsules), pills, and granules, can be optionally scored or prepared with coatings and shells, such as enteric coatings and other coatings well known in the pharmaceutical formulation art. They can also be formulated to provide sustained or controlled release of the active ingredient therein, for example, using various proportions of hydroxypropylmethylcellulose, other polymer matrices, liposomes, and / or microspheres to provide the desired release profile. They can be sterilized, for example, by filtration through a bacteria-retaining filter or by incorporating a sterilizing agent in the form of a sterile solid composition that can be dissolved in sterile water or other injectable sterile medium immediately before use. These compositions can also optionally contain opacifying agents and can be compositions that release the active ingredient(s) only, or preferentially, in a certain portion of the gastrointestinal tract, optionally in a delayed manner. Examples of embedding compositions that can be used include polymeric substances and waxes. The active ingredient can also be in micro-encapsulated form, if appropriate, with one or more of the above-mentioned excipients.

[0203] Liquid dosage forms useful for oral administration include pharmaceutically acceptable emulsions, lyophilized formulations for reconstitution, microemulsions, solutions, suspensions, syrups, and elixirs.In addition to the active ingredient, the liquid dosage form may contain, for example, an inert diluent commonly used in the art, such as water or other solvents, cyclodextrin and its derivatives, solubilizers and emulsifiers, such as ethyl alcohol, isopropyl alcohol, ethyl carbonate, ethyl acetate, benzyl alcohol, benzyl benzoate, propylene glycol, 1,3-butylene glycol, oils (especially cottonseed oil, peanut oil, corn oil, germ oil, olive oil, castor oil, and sesame oil), glycerol, tetrahydrofuryl alcohol, polyethylene glycol, and fatty acid esters of sorbitan, and mixtures thereof.

[0204] Besides inert diluents, the oral compositions can also include adjuvants such as wetting agents, emulsifying and suspending agents, sweetening, flavoring, coloring, perfuming and preservative agents.

[0205] Suspensions may contain, in addition to the active compound, suspending agents such as ethoxylated isostearyl alcohols, polyoxyethylene sorbitol and sorbitan esters, microcrystalline cellulose, aluminum metahydroxide, bentonite, agar-agar, and tragacanth, and mixtures thereof.

[0206] Formulations of pharmaceutical compositions for rectal, vaginal, or urethral administration can be provided as suppositories, which can be prepared by mixing one or more active compounds with one or more suitable non-irritating excipients or carriers including, for example, cocoa butter, polyethylene glycol, a suppository wax, or a salicylate, which are solid at room temperature but liquid at body temperature and will melt in the rectal or vaginal cavity to release the active compound(s).

[0207] Formulations of the pharmaceutical composition for oral administration may be presented as a mouthwash, oral spray, or oral ointment.

[0208] Alternatively or additionally, the compositions can be formulated for delivery via a catheter, stent, wire, or other intraluminal device, which may be particularly useful for delivery to the bladder, urethra, ureter, rectum, or intestine.

[0209] Formulations which are suitable for vaginal administration also include pessaries, tampons, creams, gels, pastes, foams or spray formulations containing such carriers as are known in the art to be appropriate.

[0210] Dosage forms for topical or transdermal administration include powders, sprays, ointments, pastes, creams, lotions, gels, solutions, patches, and inhalants. The active compound may be mixed under sterile conditions with a pharmaceutically acceptable carrier and with any preservatives, buffers, or propellants which may be required.

[0211] The ointments, pastes, creams and gels may contain, in addition to the active compound, excipients such as animal and vegetable fats, oils, waxes, paraffin, starch, tragacanth, cellulose derivatives, polyethylene glycols, silicones, bentonite, silicic acid, talc and zinc oxide, or mixtures thereof.

[0212] Powders and sprays can contain, in addition to the active compound, excipients such as lactose, talc, silicic acid, aluminum hydroxide, calcium silicates and polyamide powder, or mixtures of these substances. Sprays can additionally contain customary propellants, such as chlorofluorohydrocarbons, and volatile unsubstituted hydrocarbons, such as butane and propane.

[0213] Transdermal patches have the additional advantage of providing controlled delivery of the compound of the present invention to the body.Such dosage forms can be prepared by dissolving or dispersing the active compound in a suitable medium.Absorption enhancers can also be used to increase the flux of the compound across the skin.The rate of such flux can be controlled by providing a rate-controlling membrane or by dispersing the compound in a polymer matrix or gel.

[0214] Ophthalmic formulations, eye ointments, powders, solutions, and the like are also contemplated within the scope of the present disclosure. Exemplary ophthalmic formulations are described in U.S. Patent Publication Nos. 2005 / 0080056, 2005 / 0059744, 2005 / 0031697, and 2005 / 004074, and U.S. Patent No. 6,583,124, the contents of which are incorporated herein by reference. If desired, the liquid ophthalmic formulation has properties similar to those of tears, aqueous humor, or vitreous humor, or is compatible with such fluids. A preferred route of administration is topical administration (e.g., topical administration such as eye drops, or administration via an implant).

[0215] As used herein, the phrases "parenteral administration" and "parenterally administered" refer to modes of administration other than enteral and topical administration, usually by injection, and include, but are not limited to, intravenous, intramuscular, intraarterial, intrathecal, intracapsular, intraorbital, intracardiac, intradermal, intraperitoneal, transtracheal, subcutaneous, subcuticular, intraarticular, subcapsular, subarachnoid, intraspinal and intrasternal injection and infusion.

[0216] Pharmaceutical compositions suitable for parenteral administration comprise one or more active compounds in combination with one or more pharmaceutically acceptable sterile isotonic aqueous or non-aqueous solutions, dispersions, suspensions or emulsions, or sterile powders that can be reconstituted into sterile injectable solutions or dispersions immediately before use, which may contain antioxidants, buffers, bacteriostats, solutes that render the formulation isotonic with the blood of the intended recipient, or suspending or thickening agents.

[0217] Examples of suitable aqueous and non-aqueous carriers that can be used in the pharmaceutical compositions of the present invention include water, ethanol, polyols (glycerol, propylene glycol, polyethylene glycol, etc.), and suitable mixtures thereof, vegetable oils such as olive oil, and injectable organic esters such as ethyl oleate. Proper fluidity can be maintained, for example, by the use of coating materials such as lecithin, by maintaining the required particle size in the case of dispersion, and by the use of surfactants.

[0218] These compositions may also contain adjuvants such as preservatives, wetting agents, emulsifying agents, and dispersing agents. Prevention of microbial action can be ensured by including various antibacterial and antifungal agents, for example, parabens, chlorobutanol, phenol sorbic acid, etc. It may also be desirable to include isotonic agents, such as sugars and sodium chloride, in the composition. In addition, prolonged absorption of the injectable dosage form can be brought about by including agents that delay absorption, such as aluminum monostearate and gelatin.

[0219] In some cases, in order to prolong the effect of a drug, it is desirable to delay the absorption of the drug from subcutaneous or intramuscular injection.This can be achieved by using a liquid suspension of crystalline or amorphous material with poor water solubility.The absorption rate of the drug can then depend on its dissolution rate, which in turn depends on the crystal size and crystalline form.Alternatively, the delayed absorption of the drug form of parenterally administered dosage form can be achieved by dissolving or suspending the drug in an oil vehicle.

[0220] Injectable depot forms are made by forming microencapsulated matrices of the subject compounds in biodegradable polymers such as polylactide-polyglycolide. The rate of drug release can be controlled depending on the drug-to-polymer ratio and the nature of the particular polymer used. Examples of other biodegradable polymers include poly(orthoesters) and poly(anhydrides). Depot injectable formulations can also be prepared by entrapping the drug in liposomes or microemulsions that are compatible with body tissues.

[0221] For use in the methods of the invention, the active compound can be provided per se or as a pharmaceutical composition containing 0.1 to 99.5% (more preferably, 0.5 to 90%) of the active ingredient in combination with, for example, a pharmaceutically acceptable carrier.

[0222] The method of introduction may be provided by a rechargeable or biodegradable device. A variety of sustained-release polymeric devices have been developed and tested in vivo in recent years for the controlled delivery of drugs, including proteinaceous biopharmaceuticals. A variety of biocompatible polymers (including hydrogels), including both biodegradable and non-degradable polymers, can be used to form implants for the sustained release of compounds at specific target sites.

[0223] The actual dosage level of the active ingredient in the pharmaceutical composition can be varied to obtain an amount of the active ingredient effective to achieve the desired therapeutic response for a particular patient, composition, and mode of administration without being toxic to the patient.

[0224] The selected dosage level will depend on a variety of factors, including the activity of the particular compound or combination of compounds, or esters, salts, or amides thereof, used, the route of administration, the time of administration, the rate of excretion of the particular compound(s) used, the duration of treatment, other drugs, compounds, and / or materials used in combination with the particular compound(s) used, the age, sex, weight, condition, general health, and previous medical history of the patient being treated, and similar factors well known in the medical arts.

[0225] A physician or veterinarian of ordinary skill in the art can easily determine and prescribe the therapeutically effective amount of the pharmaceutical composition required. For example, a physician or veterinarian can start by administering a pharmaceutical composition or compound at a level lower than that required to achieve the desired therapeutic effect, and gradually increase the dosage until the desired effect is achieved. A "therapeutically effective amount" refers to the concentration of a compound sufficient to elicit the desired therapeutic effect. It is generally understood that the effective amount of a compound will vary depending on the subject's weight, sex, age, and medical history. Other factors that affect the effective amount may include, but are not limited to, the severity of the subject's condition, the disorder being treated, the stability of the compound, and, if desired, other types of therapeutic agents administered together with the compound of the present invention. A larger total dose can be delivered by multiple administrations of the drug. Methods for determining efficacy and dosage are known to those skilled in the art (Isselbacher et al. (1996) Harrison's Principles of Internal Medicine 13th ed., 1814-1882, incorporated herein by reference).

[0226] Generally, a suitable daily dose of an active compound used in the compositions and methods of the invention will be that amount of the compound that is the lowest dose effective to produce a therapeutic effect. Such an effective dose will generally depend upon the factors described above.

[0227] If desired, the effective daily dose of active compound can be administered as 1, 2, 3, 4, 5, 6 or more sub-doses that are administered separately at appropriate intervals throughout the day, optionally in unit dosage form.In certain embodiments of the present invention, active compound can be administered 2 or 3 times a day.In preferred embodiments, active compound is administered once a day.

[0228] In certain embodiments, dosing follows a 3+3 design. The traditional 3+3 design does not require dose-toxicity curve modeling beyond the classical assumption of increasing toxicity with dose for cytotoxic drugs. This rule-based design proceeds with cohorts of three patients, with the first cohort treated at a starting dose deemed safe based on extrapolation from animal toxicology data, and subsequent cohorts treated at pre-fixed escalating dose levels. In some embodiments, three doses of the compound of Formula (I) are administered orally in the range of about 100 mg to about 1000 mg, e.g., about 200 mg to about 800 mg, e.g., about 400 mg to about 700 mg, e.g., about 100 mg to about 400 mg, e.g., about 500 mg to about 1000 mg, and further e.g., about 500 mg to about 600 mg. Administration is three times daily when taken without food and twice daily when taken with food. In certain embodiments, three doses of the compound of Formula (I) range from about 400 mg to about 800 mg, e.g., from about 400 mg to about 700 mg, e.g., from about 500 mg to about 800 mg, or further, for example, from about 500 mg to about 600 mg twice daily. In certain preferred embodiments, doses greater than about 600 mg are administered twice daily.

[0229] If none of the three patients in a cohort experience dose-limiting toxicity, the other three patients are treated at the next higher dose level. However, if one of the first three patients experiences dose-limiting toxicity, three more patients are treated at the same dose level. Dose escalation continues until at least two patients in a cohort of three to six patients experience dose-limiting toxicity (i.e., approximately 33% or more of patients at that dose level have dose-limiting toxicity). The recommended dose for Phase II trials is traditionally defined as the dose level immediately below this toxic dose level.

[0230] In certain embodiments, the dosing schedule is about 40 mg / m 2 ~about 100mg / m 2 , for example, about 50 mg / m 2 ~about 80mg / m 2 , and further about 70 mg / m2 ~about 90mg / m 2 and so on, 3 weeks out of a 4 week cycle, by IV.

[0231] In certain embodiments, the compounds of the present invention can be administered alone or in combination with another type of therapeutic agent.As used herein, the term "conjoint administration" refers to any form of administration of two or more different therapeutic compounds, such that the second compound is administered while the previously administered therapeutic compound is still effective in the body (for example, the two compounds are effective in the subject at the same time, and the synergistic effect of the two compounds may be included).For example, different therapeutic compounds can be administered simultaneously or sequentially, either in the same formulation or in separate formulations.In certain embodiments, different therapeutic compounds can be administered within 1 hour, 12 hours, 24 hours, 36 hours, 48 ​​hours, 72 hours, or 1 week of each other.Therefore, subjects receiving such treatment can benefit from the combined effect of different therapeutic compounds.

[0232] In certain embodiments, the combined administration of a compound of the invention with one or more additional therapeutic agent(s) (e.g., one or more additional chemotherapeutic agent(s)) provides improved efficacy compared to the separate administration of either the compound of the invention (e.g., a compound of Formula I or Ia) or the one or more additional therapeutic agent(s). In certain such embodiments, the combined administration provides an additive effect, where additive effect refers to the sum of the effects of the separate administration of the compound of the invention with the one or more additional therapeutic agent(s).

[0233] The present invention includes the use of pharmaceutically acceptable salts of the compounds of the present invention in the compositions and methods of the present invention. Salts of the compounds of the present invention are formed between an acid and a basic group of the compound (such as an amino functional group), or a base and an acidic group of the compound (such as a carboxyl functional group). In another embodiment, the compound is a pharmaceutically acceptable acid addition salt.

[0234] A "pharmaceutically acceptable salt" means any non-toxic salt that is capable of providing, directly or indirectly, a compound of the present invention upon administration to a recipient. A "pharmaceutically acceptable counterion" is an ionic portion of a salt that is not toxic when released from the salt upon administration to a recipient.

In one embodiment, pharmaceutically acceptable acid addition salts include salts formed with mineral acids such as hydrochloric acid and hydrobromic acid, and particularly salts formed with organic acids such as fumaric acid and maleic acid.

[0236] In certain embodiments, contemplated salts of the present invention include, but are not limited to, alkyl, dialkyl, trialkyl, or tetra-alkylammonium salts. In certain embodiments, contemplated salts of the present invention include, but are not limited to, L-arginine, benenthamine, benzathine, betaine, calcium hydroxide, choline, deanol, diethanolamine, diethylamine, 2-(diethylamino)ethanol, ethanolamine, ethylenediamine, N-methylglucamine, hydrabamine, 1H-imidazole, lithium, L-lysine, magnesium, 4-(2-hydroxyethyl)morpholine, piperazine, potassium, 1-(2-hydroxyethyl)pyrrolidine, sodium, triethanolamine, tromethamine, and zinc salts. In certain embodiments, contemplated salts of the present invention include, but are not limited to, Na, Ca, K, Mg, Zn, or other metal salts.

[0237] Pharmaceutically acceptable acid addition salts may also exist as various solvates, for example with water, methanol, ethanol, dimethylformamide, etc. Mixtures of such solvates may also be prepared. The source of such solvates may be from the solvent of crystallization, may be inherent in the solvent of preparation or crystallization, or may be adventitious to such solvent.

[0238] Wetting agents, emulsifying agents, and lubricating agents, such as sodium lauryl sulfate and magnesium stearate, as well as coloring agents, releasing agents, coating agents, sweetening, flavoring, and perfuming agents, preservatives, and antioxidants can also be present in the compositions.

[0239] Examples of pharmaceutically acceptable antioxidants include: (1) water-soluble antioxidants such as ascorbic acid, cysteine ​​hydrochloride, sodium disulfate, sodium metabisulfite, and sodium sulfite; (2) oil-soluble antioxidants such as ascorbyl palmitate, butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT), lecithin, propyl gallate, and α-tocopherol; and (3) metal chelators such as citric acid, ethylenediaminetetraacetic acid (EDTA), sorbitol, tartaric acid, and phosphoric acid.

[0240] While specific embodiments of the present disclosure will be described with reference to preparations and schemes, it should be understood that such embodiments are merely illustrative and illustrate only a few of the many possible specific embodiments that can represent applications of the principles of the present disclosure. Various changes and modifications will be apparent to those skilled in the art upon consideration of the benefit of this disclosure and are deemed to be within the spirit and scope of the present disclosure as further defined in the appended claims.

[0241] 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 disclosure belongs. Although other compounds or methods may be used in practice or testing, certain preferred methods are described in the context of the following preparations and schemes.

[0242] Several synthetic protocols were used to generate the compounds described herein. These synthetic protocols (see schemes below) have common intersections and can be alternatively used to synthesize the compounds described herein. [Example]

[0243] General Scheme Compounds of formula (I) and intermediates may be prepared by the general procedures shown in Schemes 1-9. Scheme 1. Scheme 1 illustrates the synthesis of intermediate A, an aryl methyl ketone. Any commercially available starting material that can be converted to an aryl methyl ketone is applicable in this case using conventional chemical reactions well known in the art. For example, acid 1 can be converted to Weinreb amide (3) by coupling the acid with methoxy(methyl)amine (2) (Step 1a). A methyl anion source, such as a Grignard reagent or methyllithium, can then be added to the Weinreb amide (Step 2a) to form the desired aryl methyl ketone, intermediate A. Alternatively, an aryl halide derivative (4) can be Stille coupled (Step 1b) to form aryl methyl ketone intermediate A. Alternatively, an aldehyde can be converted to alcohol (7) by reaction with a Grignard reagent or methyllithium (Step 1c), followed by oxidation (Step 2b).

[0244] Scheme 2. In Scheme 2, aryl methyl ketones (intermediate A) can be converted to aryl bromomethyl ketones (8) by treating intermediate A with a brominating agent such as pyridinium tribromide (Step 1d). Condensation of 8 with thiourea in a polar solvent such as ethanol at room temperature or elevated temperature provides arylaminothiazoles 9 (Step 2d). A halogen (X = bromine or iodine) substituent can be introduced at the 5-position of the arylaminothiazole by treating 9 with a suitable halogenating agent such as NBS or NIS (Step 3d) to provide intermediate B.

[0245] Scheme 3. TIFF2025160375000313.tif69128 Scheme 3 illustrates the preparation of arylaminothiazoles (intermediate C). Aryl methyl ketones (intermediate A) are coupled with aryl bromides (10) using a catalyst such as X-phos-Pd at elevated temperatures to give ketones 11 (Step 1e). Aryl bromides 10 can be obtained by suitable reactions, such as alkylation of substituted phenols with alkyl halides or alkyl triflates (see "Preparation of Intermediates" for illustrative examples). Condensation of 11 with thiourea (Step 2e) gives intermediate C.

[0246] Scheme 4. In Scheme 4, aryl bromide 10 is converted to an aryl boronic acid or pinacol boronic ester (intermediate D1 or D2) by conventional chemical reactions well known in the art (step 1f). Both D1 and D2 can be used interchangeably in the synthesis of intermediate C.

[0247] Scheme 5. TIFF2025160375000315.tif28128 Scheme 5 shows an alternative method for preparing intermediate C by coupling intermediate B with a boronic acid or pinacol boronic ester (D1 or D2) (step 1g).

[0248] Scheme 6. TIFF2025160375000316.tif23128 In Scheme 6, the amino group in intermediate C is converted to a bromine substituent in intermediate G by a CuBr2-catalyzed reaction at elevated temperature (Step 1h).

[0249] Scheme 7. TIFF2025160375000317.tif29140 Scheme 7 shows the substituent Cy 1This figure shows the preparation of intermediate G, in which the aryl group contains a nitrogen-linked group. In step 1i, the amino group in the thiazole (intermediate B) can be removed via a tert-butyl nitrite-mediated reaction to avoid complications in the next step, the halogen substitution reaction at the 5-position. After replacing the halogen at the 5-position with an amino group (step 2i), the halogen at the 2-position can be reintroduced by a simple bromination or iodination reaction (step 3i) to give intermediate G.

[0250] Scheme 8. Synthesis of compounds of formula (I), method 1. TIFF2025160375000318.tif22128 Scheme 8 illustrates method 1 for the synthesis of compounds of formula (I) by the direct sulfonamide-forming reaction of aminothiazole (intermediate C) with arylsulfonyl chlorides (Step 1j).

[0251] Scheme 9. Synthesis of compounds of formula (I), method 2. TIFF2025160375000319.tif22128 Scheme 9 illustrates Method 2 for the synthesis of compounds of Formula (I) via the Buchwald coupling reaction (Step 1k) of a bromide derivative (Intermediate G) with a sulfonamide (Intermediate R). For the synthesis of sulfonamides (Intermediate R) that are not commercially available, see the section entitled "Preparation of Intermediates."

[0252] Analysis procedure 1 H NMR spectra were performed at 400 MHz on a Gemini 400 or Varian Mercury 400 mass spectrometer equipped with an ASW 5 mm probe and were typically recorded at ambient temperature in deuterated solvents such as DO, DMSO-D, or CDCl unless otherwise noted. Chemical shift values ​​(δ) are given in parts per million (ppm) with reference to tetramethylsilane (TMS) as the internal standard.

[0253] High pressure liquid chromatography-mass spectrometry (LCMS) experiments to determine retention times (RT) and associated mass ions were performed using one of the following methods.

[0254] Mass spectra (MS) were recorded using a Micromass mass spectrometer. Typically, the method used was positive electrospray ionization, with a mass m / z scan from 100 to 1000. Liquid chromatography was performed on a Hewlett Packard 1100 Series Binary Pump & Degasser. The auxiliary detectors used were: a Hewlett Packard 1100 Series UV detector, wavelength = 220 nm, and a Sedere SEDEX 75 evaporative light scattering (ELS) detector, temperature = 46 °C, N2 pressure = 4 bar. LCT: Gradient (AcN + 0.05% TFA): (H2O + 0.05% TFA) = 5:95 (0 min) → 95:5 (2.5 min) → 95:5 (3 min). Column: YMC Jsphere 33 x 2 4 μM, 1 ml / min. MUX: Column: YMC Jsphere 33 x 2, 1 ml / min Gradient (AcN + 0.05% TFA): (HO + 0.05% TFA) = 5:95 (0 min) → 95:5 (3.4 min) → 95:5 (4.4 min). LCT2:YMC Jsphere 33×2 4μM, (AcN+0.05%TFA):(H2O+0.05%TFA)=5:95 (0 minutes) → 95:5 (3.4 minutes) → 95:5 (4.4 minutes). QU:YMC Jsphere 33 × 2 1 ml / min, (AcN + 0.08% formic acid):(H2O + 0.1% formic acid) = 5:95 (0 min) → 95:5 (2.5 min) → 95:5 (3.0 min).

[0255] Preparation of intermediates This section, "Preparation of Intermediates," presents the synthesis of common intermediates used in the preparation of the examples. It is not intended to list all intermediates. Rather, the procedures presented herein are for illustrative purposes only. No limitations or restrictions should be imposed on the methods used to synthesize the examples.

[0258] To a solution of 2-isopropylbenzoic acid (1.39 g, 8.45 mmol) in DMF (13 mL) was added HATU (6.42 g, 16.89 mmol), N,O-dimethylhydroxylamine hydrochloride (1.25 g, 12.88 mmol), and TEA (2.57 g, 25.46 mmol) at room temperature. The resulting mixture was stirred at the same temperature for 3 hours. The mixture was poured into water (100 mL) and extracted with ethyl acetate (100 mL x 2). The extract was washed with water (100 mL x 2), dried over sodium sulfate, and evaporated. The crude product thus obtained was purified by silica gel chromatography (PE / EA = 5 / 1) to give 2-isopropyl-N-methoxy-N-methylbenzamide (1.50 g, 85.5%) as a colorless oil. LCMS: MS(ESI): m / z 208 [M+H] + .

[0260] To a solution of 2-isopropyl-N-methoxy-N-methylbenzamide (1.75 g, 8.44 mmol) in THF (17 mL) was added MeMgBr (8.5 mL, 25.5 mmol, 3.0 M) under N at 0 °C. The resulting mixture was stirred at room temperature for 2 h. The mixture was poured into water (50 mL) and extracted with ethyl acetate (50 mL × 2). The extract was washed with water (40 mL × 2), dried over sodium sulfate, and evaporated. The resulting residue was purified by silica gel chromatography (PE / EA = 10 / 1) to give 1-(2-isopropylphenyl)ethan-1-one (1.25 g, 91.3%) as a colorless oil. LCMS: MS(ESI): m / z 163 [M+H]+ .

[0262] Step 1. TIFF2025160375000324.tif23128

[0263] A mixture of 2-hydroxy-6-methylbenzoic acid (5.0 g, 32.9 mmol), potassium carbonate (18.16 g, 131.6 mmol), and 2-iodopropane (19.58 g, 115 mmol) in DMF (90 mL) was stirred overnight at 50° C. LCMS showed that 2-hydroxy-6-methyl-benzoic acid remained, so additional 2-iodopropane (11.19 g, 65.8 mmol) and potassium carbonate (9.08 g, 65.8 mmol) were added at room temperature, and the reaction mixture was stirred for an additional 4 hours at 50° C. After cooling to room temperature, water (250 mL) was added and extracted with ethyl acetate (80 mL×3). The combined organic layers were washed with brine (100 mL × 3), dried over sodium sulfate, filtered, concentrated under reduced pressure, and the residue was purified by silica gel chromatography (8% ethyl acetate in petroleum ether) to give the product isopropyl 2-isopropoxy-6-methylbenzoate as a colorless oil (7.648 g, 99% yield).
