Abstract
Description
COMPOUND, PHARMACEUTICAL COMPOSITION, AND METHOD FOR INHIBITING THE ACTIVITY OF THE MCT4 MONOCARBOXYLATE TRANSPORTER
[001] This application claims the benefit of priority under U.S. Provisional Application No. 62 / 433,113, filed December 12, 2016, the contents of which are incorporated by reference as if written herein in their entirety.
[002] New heterocyclic compositions and compounds are disclosed in this document, and their application as pharmaceutical products for the treatment of diseases. Methods for inhibiting MCT4 activity in a human or animal subject for the treatment of diseases such as cancer are also provided.
[003] Lactic acid export from glycolytic cells is typically mediated by the monocarboxylate transporter MCT4. MCT4 exhibits weak affinity for lactate (Km = 28 mM) coupled with a high turnover rate, allowing the rapid export of large amounts of lactic acid. MCT4 expression is normally limited to highly glycolytic tissues such as white muscle fibers, lymphocytes, astrocytes, and Sertoli cells. Although MCT4 is absent in most normal tissues, its expression is highly upregulated and correlates with poor survival in many cancer indications, including colorectal cancer, glioma, head and neck cancer, triple-negative breast cancer, prostate cancer, KRAS mutant lung cancer, liver cancer, and kidney cancer.
[004] The correlation between MCT4 expression and poor cancer outcome appears to be of significant functional consequence in multiple cancer models. A Petition 870220002363, dated 10 / 01 / 2022, page 5 / 422 2 / 412 Stable expression of MCT4 is highly tumorigenic in a Ras-transformed, respiration-deficient fibroblast xenograft model. Conversely, silencing MCT4 slows or eliminates tumor growth in xenograft models of breast cancer, colorectal cancer, and glioma. MCT4 expression is required for angiogenesis mediated by the inflammatory cytokine IL-8 in xenograft models of breast and colon cancer. MCT4 has also been shown to play important roles in cancer cell migration, invasion, and various aspects of the Warburg effect (e.g., glucose proliferation, extracellular acidification, and lactate secretion).
[005] Inhibition of lactic acid export mediated by MCT4 may be an effective strategy to impair the Warburg effect in cancer. Unfortunately, selective and potent MCT4 inhibitors have not been described. Moderate to weak MCT4 inhibitors are known (e.g., phloretin and α-CN-4-OH-cinnamate); however, these compounds promiscuously inhibit several other transporters, including MCT1.
[006] Thus, there is a need for selective and potent MCT4 inhibitors for use in the treatment or prevention of cancer. DETAILED DESCRIPTION
[007] Innovative pharmaceutical compounds and compositions have been revealed, some of which have been shown to inhibit MCT4, along with methods for synthesizing and using the compounds, including methods for treating MCT4-mediated diseases in a patient by administering the compounds.

Examples include trimethylsilyl, tert-butyldimethylsilyl, triphenylsilyl, and the like.
[0408] Any definition in this document may be used in combination with any other definition to describe a compound structural group. By convention, the last element of any such definition is the one that attaches to the original chemical moiety. For example, the compound group alkylamido would represent an alkyl group attached to the original molecule via an amido group, and the term alkoxyalkyl would represent an alkoxy group attached to the original molecule via an alkyl group.
[0409] When a group is defined as being null, it is understood that the said group is absent.

An optionally substituted group can be unsubstituted (e.g., -CH2CH3), fully substituted (e.g., CF2CF3), monosubstituted (e.g., -CH2CH2F), or substituted at any level between fully substituted and monosubstituted (e.g., -CH2CF3).When substituents are cited without qualification as to substitution, both substituted and unsubstituted forms are covered. When a substituent is qualified as substituted, the substituted form is specifically desired. Additionally, different sets of optional substitutions to a particular chemical moiety may be defined as needed; in such cases, the optional substitution will be as defined, often immediately following the optionally substituted phrase.
[0411] The term R or the term R', appearing alone and without a numerical designation, unless otherwise defined, refers to a chemical moiety chosen from hydrogen, alkyl, cycloalkyl, heteroalkyl, aryl, heteroaryl and Petition 870220002363, dated 10 / 01 / 2022, p. 58 / 422 55 / 412 heterocycloalkyl, any of which may be optionally substituted. Such R and R' groups should be understood as being optionally substituted as defined herein. Whether or not an R group has a numerical designation, each R group, including R, R' and Rn where n = (1, 2, 3, ... n), each substituent and each term should be understood as being independent of each other in terms of group selection. If any variable, substituent or term (e.g., aryl, heterocycle, R, etc.) occurs more than once in a generic formula or structure, its definition in each occurrence is independent of the definition in each other occurrence. Those skilled in the art will further recognize that certain groups may be attached to an original molecule or may occupy a position in a chain of elements from either end as written.For example, an asymmetric group, such as -C(O)N(R)-, can be attached to the original chemical portion on either the carbon or the nitrogen.
[0412] There are asymmetric centers in the compounds disclosed in this document. These centers are designated by the symbols R or S, depending on the configuration of substituents around the chiral carbon atom. It should be understood that the invention encompasses all stereochemical isomeric forms, including diastereomeric, enantiomeric, and epimeric forms, as well as d-isomers and 1-isomers and mixtures thereof. The individual stereoisomers of the compounds can be prepared synthetically from commercially available starting materials containing chiral centers or by preparing mixtures of enantiomeric products followed by separation, such as conversion of Petition 870220002363, dated 10 / 01 / 2022, p. 59 / 422 56 / 412 a mixture of diastereomers followed by separation or recrystallization, chromatographic techniques, direct separation of enantiomers on chiral chromatographic columns, or any other suitable method known in the art. The starting compounds of particular stereochemistry are either commercially available or can be made and solved by techniques known in the art. Additionally, the compounds disclosed herein may exist as geometric isomers. The present invention includes all cis, trans, syn, anti, entgegen (E), and zusamen (Z) isomers as well as appropriate mixtures thereof. Additionally, the compounds may exist as tautomers; all tautomeric isomers are provided by this invention. Furthermore, the compounds disclosed herein may exist in non-solvated forms as well as solvated with pharmaceutically acceptable solvents such as water, ethanol, and the like.In general, solvated forms are considered equivalent to non-solvated forms.
[0413] The term bond refers to a covalent bond between two atoms or two chemical moieties when the atoms joined by the bond are considered part of the larger substructure. A bond can be single, double, or triple, unless otherwise specified. A dashed line between two atoms in a drawing of a molecule indicates that an additional bond may be present or absent at that position.
[0414] The term disease as used in this document is intended to be generally synonymous with, and is used interchangeably with, the terms disorder, syndrome and condition (as in medical condition), wherein all Petition 870220002363, dated 10 / 01 / 2022, p. 60 / 422 57 / 412 reflect an abnormal condition of the human or animal body or one of its parts that impairs normal functioning, is typically manifested by distinguishing signs and symptoms, and causes the human or animal to have a reduced lifespan or quality of life.
[0415] The term combination therapy means the administration of two or more therapeutic agents to treat a therapeutic condition or disorder described in this disclosure. Such administration includes the co-administration of these therapeutic agents in a substantially simultaneous manner, such as in a single capsule having a fixed ratio of active ingredients or in multiple separate capsules for each active ingredient. In addition, this administration also includes the use of each type of therapeutic agent in a sequential manner. In both cases, the treatment regimen will provide the beneficial effects of the drug combination in the treatment of the conditions or disorders described herein.
[0416] The term MCT4 inhibitor is used in this document to refer to a compound that exhibits an IC50 with respect to MCT4 activity of not more than about 100 μM and, more typically, not more than about 50 μM, as measured in the MCT4 enzyme assay described herein in general. IC50 is the concentration of inhibitor that reduces the activity of an enzyme (e.g., MCT4) to half the maximum level. Certain compounds disclosed in this document have been found to exhibit inhibition against MCT4. In certain embodiments, the compounds will exhibit an IC50 with respect to MCT4 of not more than about 10 μM; in further embodiments, the compounds will exhibit an IC50 with respect to MCT4 Petition 870220002363, dated 10 / 01 / 2022, page 61 / 422 58 / 412 of no more than about 5 μM; in still other embodiments, the compounds will exhibit an IC50 with respect to MCT4 of no more than about 1 μM; in yet other embodiments, the compounds will exhibit an IC50 with respect to MCT4 of no more than about 200 nM, as measured in the MCT4 binding assay described herein.
[0417] The phrase therapeutically effective is intended to qualify the quantity of active ingredients used in the treatment of a disease or disorder or in the effect of a clinical endpoint.
[0418] The term therapeutically acceptable refers to those compounds (or salts, prodrugs, tautomers, zwitterionic forms, etc.) that are suitable for use in contact with patient tissues without undue toxicity, irritation and allergic response, are proportionate to a reasonable risk / benefit ratio and are effective for their intended use.
[0419] As used in this document, reference to the treatment of a patient is intended to include prophylaxis. Treatment may also be preemptive in nature, that is, it may include the prevention of disease. Prevention of a disease may involve complete protection against the disease, for example, as in the case of preventing infection with a pathogen, or it may involve preventing the progression of the disease. For example, prevention of a disease may not mean the total exclusion of any disease-related effect at any level, but instead may mean preventing the symptoms of a disease at a clinically significant or detectable level. Prevention of Petition 870220002363, dated 10 / 01 / 2022, p. 62 / 422 59 / 412 diseases can also mean preventing the progression of a disease to a later stage.
[0420] The term patient is generally synonymous with the term subject and includes all mammals, including humans. Examples of patients include humans, livestock such as cows, goats, sheep, pigs and rabbits, and pets such as dogs, cats, rabbits and horses. Preferably, the patient is a human being.
[0421] The term prodrug refers to a compound that is made more active in vivo. Certain compounds disclosed herein may also exist as prodrugs, as described in Hydrolysis in Drug and Prodrug Metabolism: Chemistry, Biochemistry and Enzymology (Testa, Bernard and Mayer, Joachim M. Wiley-VHCA, Zurich, Switzerland 2003). The prodrugs of the compounds disclosed herein are structurally modified forms of the compound that readily undergo chemical changes under physiological conditions in order to provide the compound. Furthermore, prodrugs can be converted into the compound by chemical or biochemical methods in an ex vivo environment. For example, prodrugs can be slowly converted into a compound when placed in a transdermal adhesive reservoir with a suitable enzyme or chemical reagent.Prodrugs are often useful because, in some situations, they can be easier to administer than the original compound or drug. For example, they may be bioavailable for oral administration while the original drug is not. The prodrug may also have improved solubility in pharmaceutical compositions compared to the original drug. A wide variety of prodrug derivatives exist. Petition 870220002363, dated 10 / 01 / 2022, p. 63 / 422 60 / 412 known in the art, such as those that depend on hydrolytic cleavage or oxidative activation of the prodrug. An example, without limitation, of a prodrug would be a compound that is administered as an ester (the prodrug) but is then metabolically hydrolyzed into the carboxylic acid, the active entity. Additional examples include peptidyl derivatives of a compound.
[0422] The compounds disclosed in this document may exist as therapeutically acceptable salts. The present invention includes the above-listed compounds in the form of salts, including acid addition salts. Suitable salts include those formed with both organic and inorganic acids. Such acid addition salts will normally be pharmaceutically acceptable. However, salts of non-pharmaceutically acceptable salts may be useful in the preparation and purification of the compound in question. Base addition salts may also be formed and be pharmaceutically acceptable. For a more complete discussion of the preparation and selection of salts, see Pharmaceutical Salts: Properties, Selection, and Use (Stahl, P. Heinrich. Wiley-VCHA, Zurich, Switzerland, 2002).

[0479] Metabolic syndrome (also known as metabolic syndrome X) is characterized by having at least three of the following symptoms: insulin resistance; abdominal fat – in men this is defined as a waist circumference of 101.6 centimeters (40 inches) or greater, in women 88.9 centimeters (35 inches) or greater; high blood sugar levels – at least 110 milligrams per deciliter (mg / dL) after fasting; high triglycerides – at least 150 mg / dL in the bloodstream; low HDL – less than 40 mg / dL; prothrombotic state (e.g., high levels of plasminogen activator inhibitor or fibrinogen in the blood); or blood pressure of 130 / 85 mmHg or higher. A connection has been found between metabolic syndrome and other conditions such as obesity, high blood pressure, and high LDL cholesterol levels, all of which are risk factors for cardiovascular disease. For example, an increased link has been shown between metabolic syndrome and atherosclerosis.People with metabolic syndrome are also more likely to develop type 2 diabetes, as well as PCOS (polycystic ovary syndrome) in women and prostate cancer in men. Petition 870220002363, dated 10 / 01 / 2022, page 89 / 422 86 / 412
[0480] As described above, insulin resistance can manifest in several ways, including type 2 diabetes. Type 2 diabetes is the condition most obviously linked to insulin resistance. Compensatory hyperinsulinemia helps maintain normal glucose levels, often for decades, before explicit diabetes develops. Eventually, the beta cells of the pancreas are unable to overcome insulin resistance through hypersecretion. Glucose levels rise, and a diagnosis of diabetes can be made. Patients with type 2 diabetes remain hyperinsulinemic until they are in an advanced stage of the disease. As described above, insulin resistance can also correlate with hypertension. Half of patients with essential hypertension are insulin resistant and hyperinsulinemic, and there is evidence that blood pressure is linked to the degree of insulin resistance.Hyperlipidemia is also associated with insulin resistance. The lipid profile of patients with type 2 diabetes includes increased serum levels of triglycerides and very low-density lipoprotein cholesterol, and sometimes a decreased level of low-density lipoprotein cholesterol. Insulin resistance has been found in people with low levels of high-density lipoprotein. Insulin levels have also been linked to the synthesis of very low-density lipoprotein and plasma triglyceride levels.
[0481] Consequently, methods are also revealed for treating insulin resistance in a subject comprising selecting a subject who needs treatment for insulin resistance; and administering to the subject an effective amount of a compound that inhibits MCT4. Petition 870220002363, dated 10 / 01 / 2022, page 90 / 422 87 / 412
[0482] The specific diseases to be treated by the compounds, compositions, and methods disclosed herein are those mediated, at least in part, by MCT4. Consequently, methods are disclosed herein: to reduce glycogen accumulation in a subject; to raise HDL or HDLc, lower LDL or LDLc, shift LDL particle size from small to normal dense LDL, lower VLDL, lower triglycerides, or inhibit cholesterol absorption in a subject; to reduce insulin resistance, enhance glucose utilization, or lower blood pressure in a subject; to reduce visceral fat in a subject; to reduce serum transaminases in a subject; or to treat disease; all of which comprise administering a therapeutic amount of a compound as described herein to a patient in need thereof. In further embodiments, the disease to be treated may be a metabolic disease.In an additional modality, the metabolic disease may be selected from the group consisting of: obesity, diabetes mellitus, especially type 2 diabetes, hyperinsulinemia, glucose intolerance, metabolic syndrome X, dyslipidemia, hypertriglyceridemia, hypercholesterolemia, and hepatic steatosis. In other modalities, the disease to be treated may be selected from the group consisting of: cardiovascular diseases including vascular disease, atherosclerosis, coronary heart disease, cerebrovascular disease, heart failure, and peripheral vascular disease. In preferred modalities, the above methods do not result in the induction or maintenance of a hypoglycemic state.
[0483] In addition to being useful for human treatment, certain compounds and formulations disclosed in Petition 870220002363, dated 10 / 01 / 2022, page 91 / 422 88 / 412 of this document may also be useful for veterinary treatment of companion animals, exotic animals and farm animals, including mammals, rodents and similar animals.
