AI Technical Summary
Existing LDH inhibitors lack potency, selectivity, and bioavailability for effective cancer treatment, and there is a need for compounds that can target LDHA and/or LDHB with improved therapeutic potential.
Development of novel compounds of formula (I) that selectively inhibit LDHA and/or LDHB, offering enhanced solubility, permeability, and pharmacokinetic profiles for cancer treatment, as well as methods to treat cancer and fibrosis.
The compounds effectively inhibit LDHA and/or LDHB activity, re-sensitizing cancer cells to anti-cancer agents and providing therapeutic benefits for cancer and fibrosis treatment.
Description
BACKGROUND
[0001] Agents that target enzymes involved in cancer cell metabolism offer an attractive therapeutic route in view of the potential to preferentially target cancer tissue over normal tissue. While normal tissue typically uses glycolysis only when the oxygen supply is low, cancer tissue relies heavily on aerobic glycolysis regardless of the oxygen supply level. This property is known as the Warburg effect (Vander Heiden et al., Science, 2009, 324(5930): 1029-1033). Lactate dehydrogenase (LDH) is involved in the final step of glycolysis, in which pyruvate is converted to lactate. The decrease in the rate of pyruvate entering the TCA (tricarboxylic acid) cycle and the concurrent increase in lactate production is vital for the growth and survival of tumors. There are two different subunits of LDH, LDHA and LDHB, but both subunits have the same active site and catalyze the conversion of pyruvate to lactate. In cancer patients, serum total lactate dehydrogenase (LDH5, a tetramer of LDHA sub-units; the major LDH isoenzyme involved in glycolysis) levels are often increased, and the gene for LDHA, is up-regulated. Tumor cells can then metabolize lactate as an energy source. Inhibition of LDH results in the stimulation of mitochondrial respiration as a compensatory mechanism. LDH inhibition is expected to reduce the ability of the cell to effectively metabolize glucose and reduce tumor cell proliferation and tumor growth. Thus, compounds that inhibit LDH activity have potential for the development of anti-cancer therapeutics.
[0002] LDHA inhibitors have been known previously. For example, gossypol is a nonselective inhibitor of LDH that blocks the binding of NADH, with a K i for LDHA and lactate dehydrogenase B (LDHB) of 1.9 and 1.4 µM, respectively (Doherty et al., J. Clin. Invest., 2013, 123(9): 3685-3692). Billiard et al. (Cancer and Metabolism, 2013, 1(19): 1-17) reports that certain derivatives of 3-((3-carbamoyl-7-(3,5-dimethylisoxazol-4-yl)-6-methoxyquinolin-4-yl) amino) benzoic acid are potent inhibitors of LDH and were 10- to 80-fold more selective for LDHA inhibition than LDHB inhibition. However, the in vivo bioavailability of the inhibitors was found to be poor.
[0003] In view of the foregoing, there remains a need to provide novel LDH inhibitors with improved potency, selectivity, and / or bioavailability for the treatment of cancer. Note that WO2013092753 discloses indole derivative inhibitors of lactate dehydrogenase (LDH).SUMMARY
[0004] The present disclosure generally relates to compounds of formula (I) in which Ar 1< , R 1< , U, V, W, X, and p are as described herein (such compounds not as such according to the claimed invention, which is narrower in scope). It has been discovered that a compound defined by formula (I) is effective in inhibiting lactate dehydrogenase A (LDHA) and / or lactate dehydrogenase B (LDHB) activity, thereby making the compound effective in treating cancer. It has also been discovered that inhibitors of LDHA and / or LDHB are useful for treating fibrosis, including idiopathic pulmonary fibrosis. It is envisioned that a compound of formula (I) is desirable for treating cancer because the compound tends to be selective for LDHA and / or LDHB relative to other dehydrogenases (e.g., GAPDH and PHGDH) and / or have a desired solubility, permeability, and / or pharmacokinetics profile (e.g., ADME) for an anti-cancer agent.
[0005] Thus, the disclosure further describes a method of treating cancer in a patient comprising administering to the patient an effective amount of the compound of formula (I) or a prodrug or a pharmaceutically acceptable salt thereof (such method not as such according to the claimed invention).
[0006] The disclosure describes a method of treating fibrosis, including idiopathic pulmonary fibrosis, in a patient comprising administering to the patient an effective amount of the compound of formula (I) or a prodrug or a pharmaceutically acceptable salt thereof (such method not as such according to the claimed invention).
[0007] Also described is a method of treating a patient with cancer cells resistant to an anti-cancer agent, comprising administering to the patient an effective amount of the compound of formula (I) or a prodrug or a pharmaceutically acceptable salt thereof, and the anti-cancer agent, whereby the compound, prodrug, or pharmaceutically acceptable salt thereof re-sensitizes the cancer cells to the anti-cancer agent (such method not as such according to the claimed invention).
[0008] Also described is a method of inhibiting lactate dehydrogenase A (LDHA) and / or lactate dehydrogenase B activity in a cell comprising administering a compound of formula (I) or a prodrug or a pharmaceutically acceptable salt thereof to a cell (such method not as such according to the claimed invention). Note however that the claimed invention is set out in the appended claims.DETAILED DESCRIPTION OF THE INVENTION

[0054] The use of the terms "a" and "an" and "the" and "at least one" and similar referents in the context of describing the invention (especially in the context of the following claims) are to be construed to cover both the singular and the plural, unless otherwise indicated herein or clearly contradicted by context. The use of the term "at least one" followed by a list of one or more items (for example, "at least one of A and B") is to be construed to mean one item selected from the listed items (A or B) or any combination of two or more of the listed items (A and B), unless otherwise indicated herein or clearly contradicted by context. The terms "comprising," "having," "including," and "containing" are to be construed as open-ended terms (i.e., meaning "including, but not limited to,") unless otherwise noted. Recitation of ranges of values herein are merely intended to serve as a shorthand method of referring individually to each separate value falling within the range, unless otherwise indicated herein, and each separate value is incorporated into the specification as if it were individually recited herein. All methods described herein can be performed in any suitable order unless otherwise indicated herein or otherwise clearly contradicted by context. The use of any and all examples, or language denoting examples (e.g., "such as") provided herein, is intended merely to better illuminate the invention and does not pose a limitation on the scope of the invention unless otherwise claimed. No language in the specification should be construed as indicating any non-claimed element as essential to the practice of the invention.
[0055] The term "substituted", as used herein, means that any one or more hydrogens on the designated atom or group is replaced with a selection from the indicated group, provided that the designated atom's normal valence is not exceeded. When the substituent is oxo (i.e., =O) then 2 hydrogens on the atom are replaced. When an oxo group substitutes a heteroaromatic moiety, the resulting molecule can sometimes adopt tautomeric forms. For example a pyridyl group substituted by oxo at the 2- or 4-position can sometimes be written as a pyridine or hydroxypyridine. Combinations of substituents and / or variables are permissible only if such combinations result in stable compounds or useful synthetic intermediates. A stable compound or stable structure is meant to imply a compound that is sufficiently robust to survive isolation from a reaction mixture and subsequent formulation into an effective therapeutic agent. Unless otherwise specified, substituents are named into the core structure. For example, it is to be understood that aminoalkyl means the point of attachment of this substituent to the core structure is in the alkyl portion and alkylamino means the point of attachment is a bond to the nitrogen of the amino group.
[0056] Suitable groups that may be present on a "substituted" or "optionally substituted" position include, but are not limited to, halogen; cyano; -OH; nitro; alkyl groups (including cycloalkyl and (cycloalkyl)alkyl groups) having 1 to about 8 carbon atoms, or 1 to about 6 carbon atoms; alkenyl and alkynyl groups including groups having one or more unsaturated linkages and from 2 to about 8, or 2 to about 6 carbon atoms; alkoxy groups having one or more oxygen linkages and from 1 to about 8, or from 1 to about 6 carbon atoms; aryloxy such as phenoxy; alkylthio groups including those having one or more thioether linkages and from 1 to about 8 carbon atoms, or from 1 to about 6 carbon atoms. For example, suitable groups that may be present on a "substituted" or "optionally substituted" position include hydroxyl, halogen, cyano, alkyl groups, and alkoxy groups.
[0057] In any of the embodiments above, the term "alkyl" implies a straight-chain or branched alkyl substituent containing from, for example, from about 1 to about 8 carbon atoms, e.g., from about 1 to about 6 carbon atoms. Examples of alkyl group include methyl, ethyl, n-propyl, isopropyl, n-butyl, sec-butyl, isobutyl, tert-butyl, n-pentyl, isopentyl, n-hexyl, and the like. This definition also applies wherever "alkyl" occurs as part of a group, such as, e.g., in C 3 -C 6 cycloalkylalkyl, hydroxyalkyl, haloalkyl (e.g., monohaloalkyl, dihaloalkyl, and trihaloalkyl), cyanoalkyl, aminoalkyl, alkylamino, dialkylamino, arylalkyl, etc. The alkyl can be substituted or unsubstituted, as described herein. Even in instances in which the alkyl is an alkylene chain (e.g., -(CH 2 ) n -), the alkyl group can be substituted or unsubstituted. An example of a substituted alkylene chain includes -CF 2 -cyclopropyl.
[0058] In any of the embodiments above, the term "alkenyl," as used herein, means a linear alkenyl substituent containing from, for example, about 2 to about 8 carbon atoms (branched alkenyls are about 3 to about 8 carbons atoms), e.g., from about 3 to about 6 carbon atoms (branched alkenyls are about 3 to about 6 carbons atoms). In accordance with an embodiment, the alkenyl group is a C 2 -C 4 alkenyl. Examples of alkenyl group include ethenyl, allyl, 2-propenyl, 1-butenyl, 2-butenyl, 1-pentenyl, 2-pentenyl, 3-pentenyl, 1-hexenyl, and the like. The alkenyl can be substituted or unsubstituted, as described herein.
[0059] In any of the embodiments above, the term "alkynyl," as used herein, means a linear alkynyl substituent containing at least one carbon-carbon triple bond and from, for example, about 2 to about 8 carbon atoms (branched alkynyls are about 4 to about 12 carbons atoms), e.g., from about 2 to about 6 carbon atoms (branched alkynyls can be from about 4 to about 8 carbon atoms), e.g., from about 2 to about 4 carbon atoms. Examples of such substituents include propynyl, propargyl, n-butynyl, pentynyl, isopentynyl, hexynyl, octynyl, and the like. The alkynyl can be substituted or unsubstituted, as described herein.
[0060] In any of the embodiments above, the term "cycloalkyl," as used herein, means a cyclic alkyl moiety containing from, for example, 3 to 6 carbon atoms or from 5 to 6 carbon atoms. Examples of such moieties include cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, and the like. The cycloalkyl can be substituted or unsubstituted, as described herein. For example, a substituted cycloalkyl includes a halo- or haloalkyl-substituted cyclopropyl, such as 2-fluorocyclopropyl, 2,2-difluorocyclopropyl, 1-(trifluoromethyl)cyclopropyl, and 2-(trifluoromethyl)cyclopropyl.
[0061] In any of the embodiments above, the term "hydrocarbyl" means an aliphatic group having the specified number of carbon atoms and the appropriate valence in view of the number of substitutions shown in the structure. Hydrocarbyl groups contain at least carbon and hydrogen, and can contain single, double, and triple carbon-carbon bonds. In certain embodiments hydrocarbyl groups optionally contain 1 or more (e.g., 1-8) heteroatoms selected from N, O, S, Si, P, or a combination thereof. Hydrocarbyl groups can be unsubstituted or substituted with one or more substituent groups up to the valence allowed by the hydrocarbyl group. For example the hydrocarbyl group may be substituted with hydroxyl, cyano, amino, halogen, oxo, cycloalkyl, 5- to 7-membered heterocycloalkyl containing 1 to 3 heteroatoms selected from N, O, and S, 5- or 6-membered heteroaryl selected with 1 to 5 heteroatoms selected from N, O, and S, and phenyl.
[0062] In any of the embodiments above, the term "hydroxy" refers to the group -OH.
[0063] In any of the embodiments above, the terms "alkoxy" and "cycloalkyloxy" embrace linear or branched alkyl and cycloalkyl groups, respectively, that are attached to a divalent oxygen. The alkyl and cycloalkyl groups are the same as described herein. The term "aryloxy" refers to substituents that have an aryl group attached to divalent oxygen. The aryl group is the same as described herein.
[0064] In any of the embodiments above, the term "halo" refers to a halogen selected from fluorine, chlorine, bromine, and iodine.
[0065] In any of the embodiments above, the term "aryl" refers to a mono, bi, or tricyclic carbocyclic ring system having one, two, or three aromatic rings, for example, phenyl, naphthyl, anthracenyl, or biphenyl. The term "aryl" refers to an unsubstituted or substituted aromatic carbocyclic moiety, as commonly understood in the art, and includes monocyclic and polycyclic aromatics such as, for example, phenyl, biphenyl, naphthyl, anthracenyl, pyrenyl, and the like. An aryl moiety generally contains from, for example, 6 to 30 carbon atoms, from 6 to 18 carbon atoms, from 6 to 14 carbon atoms, or from 6 to 10 carbon atoms. It is understood that the term aryl includes carbocyclic moieties that are planar and comprise 4n+2 π electrons, according to Hückel's Rule, wherein n = 1, 2, or 3. This definition also applies wherever "aryl" occurs as part of a group, such as, e.g., in haloaryl (e.g., monohaloaryl, dihaloaryl, and trihaloaryl), arylalkyl, etc. The aryl can be substituted or unsubstituted, as described herein.
[0066] In any of the embodiments above, the term "heteroaryl" refers to aromatic 5 or 6 membered monocyclic groups, 9 or 10 membered bicyclic groups, and 11 to 14 membered tricyclic groups which have at least one heteroatom (O, S, or N) in at least one of the rings. Each ring of the heteroaryl group containing a heteroatom can contain one or two oxygen or sulfur atoms and / or from one to four nitrogen atoms provided that the total number of heteroatoms in each ring is four or less and each ring has at least one carbon atom. The fused rings completing the bicyclic and tricyclic groups may contain only carbon atoms and may be saturated, partially saturated, or unsaturated. The nitrogen and sulfur atoms may optionally be oxidized, and the nitrogen atoms may optionally be quaternized. Heteroaryl groups which are bicyclic or tricyclic must include at least one fully aromatic ring but the other fused ring or rings may be aromatic or non-aromatic. The heteroaryl group may be attached at any available nitrogen or carbon atom of any ring. Illustrative examples of heteroaryl groups are pyridinyl, pyridazinyl, pyrimidyl, pyrazinyl, benzimidazolyl, triazinyl, imidazolyl, (1,2,3)- and (1,2,4)-triazolyl, pyrazinyl, tetrazolyl, furyl, pyrrolyl, thienyl, isothiazolyl, thiazolyl, isoxazolyl, and oxadiazolyl.

In some instances, "Het" is a heteroaryl, as described herein.
[0068] The term "heterocycloalkyl" means a stable, saturated, or partially unsaturated monocyclic, bicyclic, and spiro ring system containing 3 to 7 ring members of carbon atoms and other atoms selected from nitrogen, sulfur, and / or oxygen. In an aspect, a heterocycloalkyl is a 5, 6, or 7-membered monocyclic ring and contains one, two, or three heteroatoms selected from nitrogen, oxygen, and sulfur. The heterocycloalkyl may be attached to the parent structure through a carbon atom or through any heteroatom of the heterocycloalkyl that results in a stable structure.

The heterocycloalkyl can be substituted or unsubstituted, as described herein.
[0069] In any of the embodiments above, the alkyl, alkoxy, and alkylamino groups can be linear or branched.
[0070] Where indicated, any substituent of Formula I that is not hydrogen (e.g., C 1 -C 8 alkyl, C 2 -C 8 alkenyl, C 2 -C 8 alkynyl, C 3 -C 6 cycloalkyl, C 3 -C 6 cycloalkylalkyl, aryl, arylalkyl, heteroaryl, heteroarylalkyl, heterocycloalkyl, or heterocycloalkylalkyl) can be an optionally substituted moiety. The substituted moiety typically comprises at least one substituent (e.g., 1, 2, 3, 4, 5, 6, etc.) in any suitable position (e.g., 1-, 2-, 3-, 4-, 5-, or 6-position, etc.). When an aryl group is substituted with a substituent, e.g., halo, amino, alkyl, OH, alkoxy, and others, the aromatic ring hydrogen is replaced with the substituent and this can take place in any of the available hydrogens, e.g., 2, 3, 4, 5, and / or 6-position wherein the 1-position is the point of attachment of the aryl group in the compound of the present invention. Suitable substituents include, e.g., halo, alkyl, alkenyl, alkynyl, hydroxy, nitro, cyano, amino, alkylamino, alkoxy, aryloxy, aralkoxy, carboxyl, carboxyalkyl, carboxyalkyloxy, amido, alkylamido, haloalkylamido, aryl, heteroaryl, and heterocycloalkyl, each of which is described herein. In some instances, the substituent is at least one alkyl, halo, and / or haloalkyl (e.g., 1 or 2).
[0071] In any of the embodiments above, whenever a range of the number of atoms in a structure is indicated (e.g., a C 1-12 , C 1-8 , C 1-6 , or C 1-4 alkyl, cycloalkyl, etc.), it is specifically contemplated that any sub-range or individual number of carbon atoms falling within the indicated range also can be used. Thus, for instance, the recitation of a range of 1-8 carbon atoms (e.g., C 1 -C 8 ), 1-6 carbon atoms (e.g., C 1 -C 6 ), 1-4 carbon atoms (e.g., C 1 -C 4 ), 1-3 carbon atoms (e.g., C 1 -C 3 ), or 2-8 carbon atoms (e.g., C 2 -C 8 ) as used with respect to any chemical group (e.g., alkyl, cycloalkyl, etc.) referenced herein encompasses and specifically describes 1, 2, 3, 4, 5, 6, 7, and / or 8 carbon atoms, as appropriate, as well as any sub-range thereof (e.g., 1-2 carbon atoms, 1-3 carbon atoms, 1-4 carbon atoms, 1-5 carbon atoms, 1-6 carbon atoms, 1-7 carbon atoms, 1-8 carbon atoms, 2-3 carbon atoms, 2-4 carbon atoms, 2-5 carbon atoms, 2-6 carbon atoms, 2-7 carbon atoms, 2-8 carbon atoms, 3-4 carbon atoms, 3-5 carbon atoms, 3-6 carbon atoms, 3-7 carbon atoms, 3-8 carbon atoms, 4-5 carbon atoms, 4-6 carbon atoms, 4-7 carbon atoms, 4-8 carbon atoms, etc., as appropriate).
[0072] The subscripts "m" and "n" represent the number of substituents, e.g., R 2< or R 3< , in which each substituent, e.g., R 2< or R 3< , can be the same or different. The subscripts m and n can be the same or different and each is either 0 or an integer from 1-5 (i.e., 1, 2, 3, 4, or 5). When m or n is 0, then the corresponding substituent, i.e., R 2< or R 3< , is not present in the compound of formula (I). The subscripts "o" and "q" represent the number of methylene repeat units. The subscripts o and q are either 0 or an integer from 1-5 (i.e., 1, 2, 3, 4, or 5). When o or q is 0, then the respective moiety does not contain any methylene repeat units.
[0073] A compound can be provided as a prodrug, which is a drug derivative or drug precursor compound that typically is inactive or less than fully active until it is converted in the body through a normal metabolic process such as, for example, hydrolysis of an ester or amide form of the drug, to the active drug. A prodrug may be selected and used instead of the parent drug because, for example, in its prodrug form it is less toxic, and / or may have better absorption, distribution, metabolism and excretion (ADME) characteristics, and the like, than the parent drug. A prodrug might also be used to improve how selectively the drug interacts with cells or processes that are not its intended target. This approach may be employed particularly, for example, to prevent or decrease adverse effects, especially in cancer treatments, which may be especially prone to having severe unintended and undesirable side effects.
[0074] The term "prodrug" denotes a derivative of a compound, which derivative, when administered to warm-blooded animals, e.g., humans, is converted into the compound (drug). For example, the enzymatic and / or chemical hydrolytic cleavage of a derivative compound of the present invention occurs in such a manner that the proven drug form is released, and the moiety or moieties split off remain nontoxic or are metabolized so that nontoxic metabolites are produced. For example, a carboxylic acid group can be esterified, e.g., with a methyl group or ethyl group to yield an ester. When an ester is administered to a subject, the ester is cleaved, enzymatically or non-enzymatically, reductively, oxidatively, or hydrolytically, to reveal the anionic group. An anionic group can be esterified with moieties (e.g., acyloxymethyl esters) which are cleaved to reveal an intermediate compound which subsequently decomposes to yield the active compound.
[0075] The prodrug can be prepared in situ during the isolation and purification of the compound of formula (I), including a compound of formula (Ia), (Ib), (Ic), or (Id), or by separately reacting the purified compound with a suitable derivatizing agent. For example, hydroxy groups can be converted into esters via treatment with a carboxylic acid in the presence of a catalyst. Examples of cleavable alcohol prodrug moieties include substituted or unsubstituted, branched or unbranched alkyl ester moieties, e.g., ethyl esters, alkenyl esters, di-alkylamino alkyl esters, e.g., dimethylaminoethyl ester, acylamino alkyl esters, acyloxy alkyl esters (e.g., pivaloyloxymethyl ester), aryl esters, e.g., phenyl ester, aryl-alkyl esters, e.g., benzyl ester, optionally substituted, e.g., with methyl, halo, or methoxy substituents aryl and aryl-alkyl esters, amides, alkyl amides, di-alkyl amides, and hydroxy amides.
[0076] The effectiveness of a particular prodrug can be determined using one or more analytical methods (e.g. pharmacokinetics, bioassays, in vivo efficacy studies, and the like) that are well-known to those of ordinary skill in the art.
[0077] A prodrug of a compound of formula (I), including a compound of formula (Ia), (Ib), (Ic), or (Id), may be prepared using routine chemical procedures. For example, a hydroxyl substituent on a compound of formula (I) can be substituted with -CO-alkyl, -CO 2 alkyl, -CONH-alkyl, -CO-alkenyl, -CO 2 -alkenyl, -CONH-alkenyl, -CO-aryl, - CO 2 -aryl, -CONH-aryl, -CO-heterocycle, -CO 2 -heterocycle, -CONH-heterocycle, or -PO 3 H 2 . Specific modifying groups of hydroxyl include, for example, acetyl, propionyl, isobutyryl, pivaloyl, palmitoyl, benzoyl, 4-methylbenzoyl, dimethylcarbamoyl, dimethylaminomethylcarbonyl, sulfo, alanyl, and fumaryl group.
[0078] An amino group can be substituted with -CO-alkyl, -CO 2 -alkyl, -CO-alkenyl, -CO 2 -alkenyl, -CO 2 -aryl, -CO-aryl, -CO-heterocycle, -CO 2 -heterocycle, or -PO 3 H 2 . The alkyl, alkenyl, aryl, and heterocycle moieties are optionally substituted by halogen, alkyl, hydroxyl, alkoxy, carboxy, amino, an amino acid residue, -PO 3 H 2 , -SO 3 H, -OPO 3 H 2 , and -OSO 3 H. Specific modifying groups of amino include, for example, tert-butyl, docosanoyl, pivaloylmethyloxy, alanyl, hexylcarbamoyl, pentylcarbamoyl, 3-methylthio-1-(acetylamino)propylcarbonyl, 1-sulfo-1-(3-ethoxy-4-hydroxyphenyl)methyl, (5-methyl-2-oxo-1,3-dioxol-4-yl)methyl, (5-methyl-2-oxo-1,3-dioxol-4-yl)methoxycarbonyl, tetrahydrofuranyl, and pyrrolidylmethyl.
[0079] Suitable modifying groups of carboxyl include, for example, methyl, ethyl, propyl, isopropyl, butyl, isobutyl, tert-butyl, pivaloyloxymethyl, carboxymethyl, dimethylaminomethyl, 1-(acetyloxy)ethyl, 1-(ethoxycarbonyloxy)ethyl, 1-(isopropyloxycarbonyloxy)ethyl, 1-(cyclohexyloxycarbonyloxy)ethyl, carboxylmethyl, (5-methyl-2-oxo-1,3-dioxol-4-yl)methyl, benzyl, phenyl, o-tolyl, morpholinoethyl, N,N-diethylcarbamoylmethyl, and phthalidyl.
[0080] In any of the embodiments above, the phrase "salt" or "pharmaceutically acceptable salt" is intended to include nontoxic salts synthesized from the parent compound which contains a basic or acidic moiety by conventional chemical methods. Generally, such salts can be prepared by reacting the free acid or base forms of these compounds with a stoichiometric amount of the appropriate base or acid in water or in an organic solvent, or in a mixture of the two. For example, an inorganic acid (e.g., hydrochloric acid, sulfuric acid, phosphoric acid, or hydrobromic acid), an organic acid (e.g., oxalic acid, malonic acid, citric acid, fumaric acid, lactic acid, malic acid, succinic acid, tartaric acid, acetic acid, trifluoroacetic acid, gluconic acid, ascorbic acid, methylsulfonic acid, or benzylsulfonic acid), an inorganic base (e.g., sodium hydroxide, potassium hydroxide, calcium hydroxide, magnesium hydroxide, or ammonium hydroxide), an organic base(e.g., methylamine, diethylamine, triethylamine, triethanolamine, ethylenediamine, tris(hydroxymethyl)methylamine, guanidine, choline, or cinchonine), or an amino acid (e.g., lysine, arginine, or alanine) can be used. Generally, non-aqueous media such as ether, ethyl acetate, ethanol, isopropanol, or acetonitrile are typical. Lists of suitable salts are found in Remington's Pharmaceutical Sciences, 18th ed., Mack Publishing Company, Easton, PA, 1990, p. 1445, and Journal of Pharmaceutical Science, 66, 2-19 (1977). For example, they can be a salt of an alkali metal (e.g., sodium or potassium), alkaline earth metal (e.g., calcium), or ammonium of salt.
[0081] The methods described (but not as such claimed) herein comprise administering a compound of formula (I) or a prodrug or a pharmaceutically acceptable salt thereof in the form of a pharmaceutical composition. In particular, a pharmaceutical composition will comprise at least one compound of formula (I) or a prodrug or a pharmaceutically acceptable salt thereof and a pharmaceutically acceptable carrier. The pharmaceutically acceptable excipients described herein, for example, vehicles, adjuvants, carriers or diluents, are well-known to those who are skilled in the art and are readily available to the public. Typically, the pharmaceutically acceptable carrier is one that is chemically inert to the active compounds and one that has no detrimental side effects or toxicity under the conditions of use.
[0082] The pharmaceutical compositions can be administered as oral, sublingual, transdermal, subcutaneous, topical, absorption through epithelial or mucocutaneous linings, intravenous, intranasal, intraarterial, intramuscular, intratumoral, peritumoral, interperitoneal, intrathecal, rectal, vaginal, or aerosol formulations. The pharmaceutical composition can be administered orally or intravenously.
[0083] The compound of formula (I) or a prodrug or a pharmaceutically acceptable salt thereof can be administered orally to a subject in need thereof. Formulations suitable for oral administration can consist of (a) liquid solutions, such as an effective amount of the compound dissolved in diluents, such as water, saline, or orange juice and include an additive, such as cyclodextrin (e.g., α-, β-, or γ-cyclodextrin, hydroxypropyl cyclodextrin) or polyethylene glycol (e.g., PEG400); (b) capsules, sachets, tablets, lozenges, and troches, each containing a predetermined amount of the active ingredient, as solids or granules; (c) powders; (d) suspensions in an appropriate liquid; and (e) suitable emulsions and gels. Liquid formulations may include diluents, such as water and alcohols, for example, ethanol, benzyl alcohol, and the polyethylene alcohols, either with or without the addition of a pharmaceutically acceptable surfactant, suspending agent, or emulsifying agent. Capsule forms can be of the ordinary hard- or soft-shelled gelatin type containing, for example, surfactants, lubricants, and inert fillers, such as lactose, sucrose, calcium phosphate, and cornstarch. Tablet forms can include one or more of lactose, sucrose, mannitol, corn starch, potato starch, alginic acid, microcrystalline cellulose, acacia, gelatin, guar gum, colloidal silicon dioxide, croscarmellose sodium, talc, magnesium stearate, calcium stearate, zinc stearate, stearic acid, and other excipients, colorants, diluents, buffering agents, disintegrating agents, moistening agents, preservatives, flavoring agents, and pharmacologically compatible carriers. Lozenge forms can comprise the active ingredient in a flavor, usually sucrose and acacia or tragacanth, as well as pastilles comprising the active ingredient in an inert base, such as gelatin and glycerin, or sucrose and acacia, emulsions, gels, and the like containing, in addition to the active ingredient, such carriers as are known in the art.
[0084] Formulations suitable for parenteral administration include aqueous and non-aqueous, isotonic sterile injection solutions, which can contain anti-oxidants, buffers, bacteriostats, and solutes that render the formulation isotonic with the blood of the intended recipient, and aqueous and non-aqueous sterile suspensions that can include suspending agents, solubilizers, thickening agents, stabilizers, and preservatives. The compound of formula (I) or a salt thereof can be administered in a physiologically acceptable diluent in a pharmaceutical carrier, such as a sterile liquid or mixture of liquids, including water, saline, aqueous dextrose and related sugar solutions, an alcohol, such as ethanol, isopropanol, or hexadecyl alcohol, glycols, such as propylene glycol or polyethylene glycol, glycerol ketals, such as 2,2-dimethyl-1,3-dioxolane-4-methanol, ethers, such as poly(ethyleneglycol) 400, an oil, a fatty acid, a fatty acid ester or glyceride, or an acetylated fatty acid glyceride with or without the addition of a pharmaceutically acceptable surfactant, such as a soap or a detergent, suspending agent, such as pectin, carbomers, methylcellulose, hydroxypropylmethylcellulose, or carboxymethylcellulose, or emulsifying agents and other pharmaceutical adjuvants.
[0085] Oils, which can be used in parenteral formulations include petroleum, animal, vegetable, or synthetic oils. Specific examples of oils include peanut, soybean, sesame, cottonseed, corn, olive, petrolatum, and mineral. Suitable fatty acids for use in parenteral formulations include oleic acid, stearic acid, and isostearic acid. Ethyl oleate and isopropyl myristate are examples of suitable fatty acid esters. Suitable soaps for use in parenteral formulations include fatty alkali metal, ammonium, and triethanolamine salts, and suitable detergents include (a) cationic detergents such as, for example, dimethyl dialkyl ammonium halides, and alkyl pyridinium halides, (b) anionic detergents such as, for example, alkyl, aryl, and olefin sulfonates, alkyl, olefin, ether, and monoglyceride sulfates, and sulfosuccinates, (c) nonionic detergents such as, for example, fatty amine oxides, fatty acid alkanolamides, and polyoxyethylene-polypropylene copolymers, (d) amphoteric detergents such as, for example, alkyl-beta-aminopropionates, and 2-alkyl-imidazoline quaternary ammonium salts, and (3) mixtures thereof.
[0086] The parenteral formulations will typically contain from about 0.5 to about 25% by weight of the inhibitors in solution. Suitable preservatives and buffers can be used in such formulations. In order to minimize or eliminate irritation at the site of injection, such compositions may contain one or more nonionic surfactants having a hydrophile-lipophile balance (HLB) of from about 12 to about 17. The quantity of surfactant in such formulations ranges from about 5 to about 15% by weight. Suitable surfactants include polyethylene sorbitan fatty acid esters, such as sorbitan monooleate and the high molecular weight adducts of ethylene oxide with a hydrophobic base, formed by the condensation of propylene oxide with propylene glycol. The parenteral formulations can be presented in unit-dose or multidose sealed containers, such as ampoules and vials, and can be stored in a freeze-dried (lyophilized) condition requiring only the addition of the sterile liquid carrier, for example, water, for injections, immediately prior to use. Extemporaneous injection solutions and suspensions can be prepared from sterile powders, granules, and tablets of the kind previously described.
[0087] The inhibitors may be made into injectable formulations. The requirements for effective pharmaceutical carriers for injectable compositions are well known to those of ordinary skill in the art. See Pharmaceutics and Pharmacy Practice, J. B. Lippincott Co., Philadelphia, Pa., Banker and Chalmers, eds., pages 238-250 (1982), and ASHP Handbook on Injectable Drugs, Toissel, 4th ed., pages 622-630 (1986).
[0088] Topically applied compositions are generally in the form of liquids (e.g., mouthwash), creams, pastes, lotions and gels. Topical administration includes application to the oral mucosa, which includes the oral cavity, oral epithelium, palate, gingival, and the nasal mucosa. In some embodiments, the composition contains at least one active component and a suitable vehicle or carrier. It may also contain other components, such as an anti-irritant. The carrier can be a liquid, solid or semi-solid. In embodiments, the composition is an aqueous solution, such as a mouthwash. Alternatively, the composition can be a dispersion, emulsion, gel, lotion or cream vehicle for the various components. In one embodiment, the primary vehicle is water or a biocompatible solvent that is substantially neutral or that has been rendered substantially neutral. The liquid vehicle can include other materials, such as buffers, alcohols, glycerin, and mineral oils with various emulsifiers or dispersing agents as known in the art to obtain the desired pH, consistency and viscosity. It is possible that the compositions can be produced as solids, such as powders or granules. The solids can be applied directly or dissolved in water or a biocompatible solvent prior to use to form a solution that is substantially neutral or that has been rendered substantially neutral and that can then be applied to the target site. In embodiments of the invention, the vehicle for topical application to the skin can include water, buffered solutions, various alcohols, glycols such as glycerin, lipid materials such as fatty acids, mineral oils, phosphoglycerides, collagen, gelatin and silicone based materials.
[0089] The compound of formula (I) or a prodrug or a pharmaceutically acceptable salt thereof, alone or in combination with other suitable components, can be made into aerosol formulations to be administered via inhalation. These aerosol formulations can be placed into pressurized acceptable propellants, such as dichlorodifluoromethane, propane, nitrogen, and the like. They also may be formulated as pharmaceuticals for non-pressured preparations, such as in a nebulizer or an atomizer.
[0090] The dose administered to the mammal, particularly human and other mammals, in accordance with the present invention should be sufficient to affect the desired response. One skilled in the art will recognize that dosage will depend upon a variety of factors, including the age, condition or disease state, predisposition to disease, genetic defect or defects, and body weight of the mammal. The size of the dose will also be determined by the route, timing and frequency of administration as well as the existence, nature, and extent of any adverse side-effects that might accompany the administration of a particular inhibitor and the desired effect. It will be appreciated by one of skill in the art that various conditions or disease states may require prolonged treatment involving multiple administrations.
[0091] The described methods (not as such according to the claimed invention) comprise administering an effective amount of a compound of formula (I) or a prodrug or a pharmaceutically acceptable salt thereof. An "effective amount" means an amount sufficient to show a meaningful benefit in an individual, e.g., promoting at least one aspect of tumor cell cytotoxicity (e.g., inhibition of growth, inhibiting survival of a cancer cell, reducing proliferation, reducing size and / or mass of a tumor (e.g., solid tumor)), or treatment, healing, prevention, delay of onset, halting, or amelioration of other relevant medical condition(s) associated with a particular cancer. The meaningful benefit observed in the patient can be to any suitable degree (10, 20, 30, 40, 50, 60, 70, 80, 90% or more). Optionally, one or more symptoms of the cancer are prevented, reduced, halted, or eliminated subsequent to administration of a compound of formula (I), including a compound of formula (Ia), (Ib), (Ic), or (Id), or a prodrug or a pharmaceutically acceptable salt thereof, thereby effectively treating the cancer to at least some degree.
[0092] Effective amounts may vary depending upon the biological effect desired in the individual, condition to be treated, and / or the specific characteristics of the compound of formula (I) ), including a compound of formula (Ia), (Ib), (Ic), or (Id), or a prodrug or a pharmaceutically acceptable salt thereof, and the individual. In this respect, any suitable dose of the compound of formula (I) or a prodrug or a pharmaceutically acceptable salt thereof can be administered to the patient (e.g., human), according to the type of cancer to be treated. Various general considerations taken into account in determining the "effective amount" are known to those of skill in the art and are described, e.g., in Gilman et al., eds., Goodman And Gilman's: The Pharmacological Bases of Therapeutics, 8th ed., Pergamon Press, 1990; and Remington's Pharmaceutical Sciences, 17th Ed., Mack Publishing Co., Easton, Pa., 1990. The dose of the compound of formula (I), including a compound of formula (Ia), (Ib), (Ic), or (Id), or a prodrug or a pharmaceutically acceptable salt thereof desirably comprises about 0.1 mg per kilogram (kg) of the body weight of the mammal (mg / kg) to about 400 mg / kg (e.g., about 0.75 mg / kg, about 5 mg / kg, about 30 mg / kg, about 75 mg / kg, about 100 mg / kg, about 200 mg / kg, or about 300 mg / kg). In another embodiment, the dose of the compound of formula (I), including a compound of formula (Ia), (Ib), (Ic), or (Id), comprises about 0.5 mg / kg to about 300 mg / kg (e.g., about 0.75 mg / kg, about 5 mg / kg, about 50 mg / kg, about 100 mg / kg, or about 200 mg / kg), about 10 mg / kg to about 200 mg / kg (e.g., about 25 mg / kg, about 75 mg / kg, or about 150 mg / kg), or about 50 mg / kg to about 100 mg / kg (e.g., about 60 mg / kg, about 70 mg / kg, or about 90 mg / kg).
[0093] In an aspect, a compound formula (I) inhibits LDHA and / or LDHB. Optionally, a compound of formula (I) is selective for LDHA and / or LDHB relative to other dehydrogenases (e.g., GAPDH and PHGDH). For example, the compound can be at least 2 times (e.g., at least 5 times, at least 10 times, at least 20 times, at least 50 times, or at least 100 times) more selective for LDHA and / or LDHB compared to one or more other dehydrogenases.
[0094] While elevated levels of LDHA are a marker for many types of cancer, the majority of which are glycolytic and / or hypoxic, LDHB can be overexpressed in some cancers (e.g., lung adenocarcinoma, prostate cancer). See, e.g., McCleland et al., Clin Cancer Res, 2013; 19(4): 773-784 and Leiblich et al., Oncogene, 2006; 25(20): 2953-2960. Thus, optionally, it is envisioned to provide a compound that can selectively inhibit LDHB or inhibit both LDHA and LDHA. Optionally, a compound of formula (I) can effectively inhibit LDHB. Therein, the compound may or may not have selectivity for LDHA, such that the inhibition is more selective for LDHA compared to LDHB or the inhibition of LDHA is about equal to the inhibition of LDHB or the inhibition is more selective for LDHB relative to LDHA.
[0095] Inhibition of LDHA and / or LDHB has been described in the art as a viable treatment of cancer. See, e.g., Billiard et al. (Cancer and Metabolism, 2013, 1(19): 1-17). Thus, certain compounds of formula (I), which includes compounds of formulas (Ia), (Ib), (Ic), and (Id), or a prodrug or pharmaceutically acceptable salt thereof, can be administered to a patient in need thereof to treat cancer. While not wishing to be bound by any particular theory, it is believed that inhibition of LDH stimulates mitrochondrial respiration and reduces cellular proliferative and tumorigenic potential. Anti-cancer activity can be measured by any suitable method, including the assays described herein. In general, activity will be measured as a function of lactate output, % ECAR (extracellular acidification rate), which quantifies glycolysis, and / or % OCR (oxygen consumption rate), which is a measure of mitochondrial respiration.
[0096] The type of cancer is not particularly limited, but optionally, the cancer is characterized as hypoxic and / or highly glycolytic relative to normal tissue of the same type. "Hypoxic" cells as used herein relates to one or more cells that are exposed, transiently or permanently, to an oxygen partial pressure (pO2) that is lower than the typical pO2 in cells in tissue that is considered as normal or healthy. Hypoxic cells can include, for example, cells with reduced or no access to vasculature, such as in a solid tumor.
[0097] Examples of cancer treatable with the described method include cancers of the head and neck, eye, skin, mouth, throat, esophagus, chest, bone, lung, colon, sigmoid, rectum, stomach, prostate, breast, ovaries, kidney, liver, pancreas, brain, intestine, heart, or adrenals. More particularly, cancers include solid tumor, sarcoma, carcinomas, fibrosarcoma, myxosarcoma, liposarcoma, chondrosarcoma, osteogenic sarcoma, chordoma, angiosarcoma, endotheliosarcoma, lymphangiosarcoma, lymphangioendothelio sarcoma, synovioma, mesothelioma, Ewing's tumor, leiomyosarcoma, rhabdomyosarcoma, colon carcinoma, pancreatic cancer, breast cancer, ovarian cancer, prostate cancer, squamous cell carcinoma, basal cell carcinoma, adenocarcinoma, sweat gland carcinoma, sebaceous gland carcinoma, papillary carcinoma, papillary adenocarcinomas, cystadenocarcinoma, medullary carcinoma, bronchogenic carcinoma, renal cell carcinoma, hepatoma, bile duct carcinoma, choriocarcinoma, seminoma, embryonal carcinoma, Wilms' tumor, cervical cancer, testicular tumor, lung carcinoma, small cell lung carcinoma, bladder carcinoma, epithelial carcinoma, glioma, astrocytoma, medulloblastoma, craniopharyngioma, ependymoma, Kaposi's sarcoma, pinealoma, hemangioblastoma, acoustic neuroma, oligodendroglioma, menangioma, melanoma, neuroblastoma, retinoblastoma, a blood-borne tumor, acute lymphoblastic leukemia, acute lymphoblastic B-cell leukemia, acute lymphoblastic T-cell leukemia, acute myeloblastic leukemia, acute promyelocytic leukemia, acute monoblastic leukemia, acute erythroleukemic leukemia, acute megakaryoblastic leukemia, acute myelomonocytic leukemia, acutenonlymphocyctic leukemia, acute undifferentiated leukemia, chronic myelocytic leukemia, chronic lymphocytic leukemia, hairy cell leukemia, or multiple myeloma. See, e.g., Harrison's Principles of Internal Medicine, Eugene Braunwald et al., eds., pp. 491 762 (15th ed. 2001). Optionally, the cancer is a solid tumor. Optionally, the cancer is selected from leukemia, melanoma, liver cancer, pancreatic cancer, lung cancer, colon cancer, brain cancer, ovarian cancer, breast cancer, prostate cancer, and renal cancer. Optionally, the cancer is liver cancer, pancreatic cancer, non-small cell lung cancer, breast cancer, or renal cancer.
[0098] Described (but not as such according to the claimed invention) is a method of treating a patient with cancer cells resistant to an anti-cancer agent, comprising administering to the patient an effective amount of the compound of formula (I), including a compound of formula (Ia), (Ib), (Ic), or (Id), or a prodrug or a pharmaceutically acceptable salt thereof, and the anti-cancer agent, whereby the compound, prodrug, or pharmaceutically acceptable salt thereof re-sensitizes the cancer cells to the anti-cancer agent. The cancer cell is the same as described herein. Optionally, the cancer cells are selected from leukemia, melanoma, liver cancer, pancreatic cancer, lung cancer, colon cancer, brain cancer, ovarian cancer, breast cancer, prostate cancer, and renal cancer. Optionally, the cancer cells are liver cancer, pancreatic cancer, non-small cell lung cancer, breast cancer, or renal cancer.

Optionally, the method comprises administering an amount of a compound, prodrug, or salt that is effective to sensitize the cancer cells to one or more therapeutic regimens (e.g., chemotherapy or radiation therapy). The terms "co-administered" or "coadministration" refer to simultaneous or sequential administration. A compound may be administered before, concurrently with, or after administration of another compound.
[0100] One or more than one, e.g., two, three, or more anti-cancer agents can be administered. In this regard, described is a pharmaceutical composition comprising a pharmaceutically acceptable carrier and a combination of the compound of formula (I), including a compound of formula (Ia), (Ib), (Ic), or (Id), or a prodrug or a pharmaceutically acceptable salt thereof and at least one anti-cancer agent (e.g., chemotherapeutic agent).
[0101] Examples of anti-cancer agents include platinum compounds (e.g., cisplatin, carboplatin, oxaliplatin), alkylating agents (e.g., cyclophosphamide, ifosfamide, chlorambucil, nitrogen mustard, thiotepa, melphalan, busulfan, procarbazine, streptozocin, temozolomide, dacarbazine, bendamustine), antitumor antibiotics (e.g., daunorubicin, doxorubicin, idarubicin, epirubicin, mitoxantrone, bleomycin, mytomycin C, plicamycin, dactinomycin), taxanes (e.g., paclitaxel and docetaxel), antimetabolites (e.g., 5-fluorouracil, cytarabine, premetrexed, thioguanine, floxuridine, capecitabine, and methotrexate), nucleoside analogues (e.g., fludarabine, clofarabine, cladribine, pentostatin, nelarabine), topoisomerase inhibitors (e.g., topotecan and irinotecan), hypomethylating agents (e.g., azacitidine and decitabine), proteosome inhibitors (e.g., bortezomib), epipodophyllotoxins (e.g., etoposide and teniposide), DNA synthesis inhibitors (e.g., hydroxyurea), vinca alkaloids (e.g., vicristine, vindesine, vinorelbine, and vinblastine), tyrosine kinase inhibitors (e.g., imatinib, dasatinib, nilotinib, sorafenib, sunitinib), monoclonal antibodies (e.g., rituximab, cetuximab, panetumumab, tositumomab, trastuzumab, alemtuzumab, gemtuzumab ozogamicin, bevacizumab), nitrosoureas (e.g., carmustine, fotemustine, and lomustine), enzymes (e.g., L- Asparaginase), biological agents (e.g., interferons and interleukins), hexamethylmelamine, mitotane, angiogenesis inhibitors (e.g., thalidomide, lenalidomide), steroids (e.g., prednisone, dexamethasone, and prednisolone), hormonal agents (e.g., tamoxifen, raloxifene, leuprolide, bicaluatmide, granisetron, flutamide), aromatase inhibitors (e.g., letrozole and anastrozole), arsenic trioxide, tretinoin, nonselective cyclooxygenase inhibitors (e.g., nonsteroidal anti-inflammatory agents, salicylates, aspirin, piroxicam, ibuprofen, indomethacin, naprosyn, diclofenac, tolmetin, ketoprofen, nabumetone, oxaprozin), selective cyclooxygenase-2 (COX-2) inhibitors, or any combination thereof.

Optionally, the mammals are from the order Carnivora, including Felines (cats) and Canines (dogs), Artiodactyla, including Bovines (cows) and Swines (pigs) or of the order Perssodactyla, including Equines (horses). Optionally, the mammals are of the order Primates, Ceboids, or Simioids (monkeys) or of the order Anthropoids (humans and apes). Optionally, the patient is a human.
[0103] Further described (but not as such according to the claimed invention) is a method of inhibiting lactate dehydrogenase A (LDHA) and / or lactate dehydrogenase b (LDHB) activity in a cell comprising administering a compound of formula (I), including a compound of formula (Ia), (Ib), (Ic), or (Id), or a prodrug or a pharmaceutically acceptable salt thereof to a cell, whereby activity of LDHA and / or LDHB is inhibited. LDHA and LDHB activity can be measured by any method known in the art for measuring enzyme inhibtions, including by the assays described herein. Typically, inhibition of LDHA and LDHB activity will be demonstrated by a decrease in lactate accumulation and / or an increase in pyruvate relative to a control sample.
