Description

STEAROYL CoA DESATURASE INHIBITORS

[0001] This application is a continuation-in-part application of U.S. Patent Application Ser.
No. 12/100,399, filed on April 9, 2008 by Koltun et al., and claims priority to U.S. Provisional Patent Application Ser. No. 60/911,225, filed April 11, 2007, the entirety of which is herein incorporated by reference.

Field of the Invention [0002] The present invention relates generally to the field of inhibitors of stearoyl-CoA
desaturase, such as 3-hydroquinazolin-4-one derivatives, and uses for such compounds in treating and/or preventing various human diseases, mediated by stearoyl-CoA
desaturase (SCD) enzymes, especially diseases related to elevated lipid levels, cardiovascular disease, cancer, diabetes, obesity, metabolic syndrome and the like.

Back rg ound [0003] Stearoyl CoA desaturases (SCD's) are A9 fatty acid desaturases. The mammalian enzymes are localized to the endoplasmic reticulum and require molecular 02 and NADH to desaturate saturated fatty acids at the A9 position and generate monounsaturated fatty acids and water in the process. The primary substrates for these enzymes are the acyl-CoA derivatives of stearic (C18) and palmitic acids (C16) with the major reaction being the conversion of stearic acid to oleic acid (C18:1). Depending on the species, 2-4 highly homologous isoforms of SCD
exist differing primarily in tissue distribution.

[0004] The best characterized SCD isozyme is SCD1 which is primarily found in liver, adipose and skeletal muscle. Deletion, mutation or inhibition of SCDI in mice and rats results in decreased hepatic triglyceride secretion, decreased hepatic steatosis, resistance to weight gain and improvements in insulin sensitivity and glucose uptake (reviewed in Ntambi et al.
(2004) Prog Lipid Res 43, 91-104; (2005), Prostaglandins Leukot. Essent. Fatty Acids 73, 35-41; and (2005) Obes. Rev. 6, 169-174. These studies combined with studies in humans showing correlations between surrogates for SCD activity and metabolic syndrome, diabetes and obesity strongly implicate SCD inhibition as a means to treat obesity, diabetes, hypertryglyceridemia and associated diseases and co-morbidities. Studies done using antisense oligonucleotide inhibitors have also demonstrated a correlation between SCD
activity and obesity and the onset of diet-induced hepatic insulin resistance; see Jiang et al. (2005) J. Clin.
Invest. 115:1030-1038G. and Gutierrez-Juarez et al. (2006) J Clin. Invest.
116:1686-1695 -t-[0005] The present invention presents compounds that are useful in inhibiting SCD activity and thus regulating lipid levels and lipid fatty acid composition. These compounds are useful in the treatment of SCD-mediated diseases such as diseases related to dyslipidemia and disorders of lipid metabolism, including, but not limited to diseases related to elevated lipid levels, cardiovascular disease, diabetes, obesity, metabolic syndrome and the like.

DETAILED DESCRIPTION OF THE INVENTION
Definitions and General Parameters [0241] As used in the present specification, the following words and phrases are generally intended to have the meanings as set forth below, except to the extent that the context in which they are used indicates otherwise.

[0242] The term "alkyl" refers to a monoradical branched or unbranched saturated hydrocarbon chain having 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19 or 20 carbon atoms. This term is exemplified by groups such as methyl, ethyl, n-propyl, iso-propyl, n-butyl, iso-butyl, t-butyl, n-hexyl, n-decyl, tetradecyl, and the like.

[0243] The term "substituted alkyl" refers to:

1) an alkyl group as defined above, having 1, 2, 3, 4 or 5 substituents, preferably 1 to 3 substituents, selected from the group consisting of alkenyl, alkynyl, alkoxy, cycloalkyl, cycloalkenyl, acyl, acylamino, acyloxy, amino, aminocarbonyl, alkoxycarbonylamino, azido, cyano, halogen, hydroxy, keto, thiocarbonyl, carboxy, carboxyalkyl, arylthio, heteroarylthio, heterocyclylthio, thiol, alkylthio, aryl, aryloxy, heteroaryl, aminosulfonyl, aminocarbonylamino, heteroaryloxy, heterocyclyl, heterocyclooxy, hydroxyamino, alkoxyamino, nitro, -SO-alkyl, -SO-aryl,-SO-heteroaryl, -S02-alkyl, S02-aryl and -S02-heteroaryl. Unless otherwise constrained by the definition, all substituents may optionally be further substituted by 1, 2, or 3 substituents chosen from alkyl, carboxy, carboxyalkyl, aminocarbonyl, hydroxy, alkoxy, halogen, CF3, amino, substituted amino, cyano, and -S(O)õR, where R is alkyl, aryl, or heteroaryl and n is 0, l or 2; or 2) an alkyl group as defined above that is interrupted by 1-10 atoms independently chosen from oxygen, sulfur and NRa , where Ra is chosen from hydrogen, alkyl, cycloalkyl, alkenyl, cycloalkenyl, alkynyl, aryl, heteroaryl and heterocyclyl.

[02881 The term "compound of Formula I " is intended to encompass the compounds of the invention as disclosed, and the pharmaceutically acceptable salts, pharmaceutically acceptable esters, prodrugs, hydrates and polymorphs of such compounds. Additionally, the compounds of the invention may possess one or more asymmetric centers, and can be produced as a racemic mixture or as individual enantiomers or diastereoisomers. The number of stereoisomers present in any given compound of Formula I depends upon the number of asymmetric centers present (there are 2" stereoisomers possible where n is the number of asymmetric centers). The individual stereoisomers may be obtained by resolving a racemic or non-racemic mixture of an intermediate at some appropriate stage of the synthesis, or by resolution of the compound of Formula I by conventional means. The individual stereoisomers (including individual enantiomers and diastereoisomers) as well as racemic and non-racemic mixtures of stereoisomers are encompassed within the scope of the present invention, all of which are intended to be depicted by the structures of this specification unless otherwise specifically indicated.

[02891 "Isomers" are different compounds that have the same molecular formula.

[02901 "Stereoisomers" are isomers that differ only in the way the atoms are arranged in space.

Synthetic Reaction Parameters [0303] The terms "solvent", "inert organic solvent" or "inert solvent" mean a solvent inert under the conditions of the reaction being described in conjunction therewith [including, for example, benzene, toluene, acetonitrile, tetrahydrofuran ("THF" ), dimethylformamide ("DMF"), chloroform, methylene chloride (or dichloromethane), diethyl ether, methanol, pyridine and the like]. Unless specified to the contrary, the solvents used in the reactions of the present invention are inert organic solvents, and the reactions are carried out under an inert gas, preferably nitrogen.

[0304] The term "q.s." means adding a quantity sufficient to achieve a stated function, e.g., to bring a solution to the desired volume (i.e., 100%).

Synthesis of the Compounds of Formula I

[0305] One method of preparing compounds of Formula I wherein Q is -C(O)-NH-is shown in Reaction Scheme I.

REACTION SCHEME I

Step 1-1: Preparation of Formula (3) [0306] The compound of formula (3) is made by forming a peptide bond between the amino group on the commercially available compound of formula (2) and the acid moiety on the commercially available nitro substituted 2-amino benzoic or nicotinic acid compound of formula (1). The reaction takes place at room temperature and is typically conducted in a polar solvent such as dichloromethane in the presence of peptide coupling agents such as 1-Ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDC) and 1-Hydroxybenzotriazole (HOBt) and may take from 2 to 5 hours. When the reaction is substantially complete, the product of formula (3) is isolated by conventional means, for example by organic phase separation using NaHCO3 and NH4C1 followed by removal of the solvent under reduced pressure and drying under high vacuum.

Step 1-2: Preparation of Formula (4) [0307] The compound of formula (4) is made by forming the quinazoline or pyrido[2,3-d]pyrimidin-4(3H)-one core via condensation with trimethylorthoformate or triethylorthoformate and (D)-10-camphorsulfinic acid. The reaction is subjected to microwave irradiation maintaining an internal reaction temperature of 160 to 200 C for 20 minutes to an hour. Once the reaction is complete, the solvent may be removed by vacuum is typically used in the next step without purification.

Step 1-3: Preparation of Formula (5) [0308] The formula (4) nitro compound is then reduced to the corresponding amine analog, compound (5), via conventional reduction techniques. Suitable methods include, but are not limited to, dissolution in p-dioxane and reaction with Na2S204 and Na2CO3 at room temperature for 12 to 24 hours. After the reaction is substantially complete, the product may be extracted by dilution with EtOAc followed by washing with saturated. NaHCO3 solution and brine. The combined organic phase can then be dried over Na2SO4 and concentrated to provide the compound of formula (5) in crude form which can be used in the next step without further puri fication.

[0309] Alternatively, the nitro group can be reduced by reaction with hydrazine and a Raney-Nickel catalyst. In this method, the nitro compound is placed in a methanol solution to which the hydrazine is added. Then the reaction mixture is heated to approximately 50 C to 80 C and the Raney-Nickel catalyst gently added to insure even and steady evolution of the nitrogen gas.
The reaction proceeds for approximately 1 hour whereupon the reaction mixture is allowed to cool to room temperature, the catalyst filtered off, and the filter cake washed with methanol.
The resulting solution may be concentrated and purified using conventional methods, i.e., chromatography using a methanol/dichloromethane gradient to provide the desired amine.
Step 1-4: Preparation of compound of Formula I

[0310] The final step in the synthesis involves the addition of the R'-XC(O)-portion of the compound. This is achieved by reacting the amino compound of formula (5) with an chloroformate, thiocarbonyl chloride, or alkanoyl chloride derivative having the desired Rl-XC(O)- moiety, i.e., a compound of formula (6). The compound of formula (5) is dissolved in p-dioxane and a solution of Na2CO3 in water is added. The compound of formula (6) is then added and the reaction is stirred at room temperature for approximately 1 to 24 hours. The mixture is then diluted with dichloromethane and more Na2CO3 solution. The resulting layers are separated in the organic phase dried with Na2SO4. The final product extracted by drying under vacuum to remove any remaining solvent followed by reverse-phase chromatography.
Alternative Preparations of Formula I

[0311] In instances where X is nitrogen, one method of preparing the Compound of Formula I
is by reacting the amino compound of formula (5) with an isocyanate derivative having the desired R1- moiety, i.e., a compound of formula (6). R'-N=C=O. As before, the compound of formula (5) is dissolved in p-dioxane and a solution of Na2CO3 in water is added. The compound of formula (6') is then added and the reaction is stirred at room temperature for approximately 1 to 24 hours. The mixture is then diluted with dichloromethane and more Na2CO3 solution. The resulting layers are separated in the organic phase and dried with Na2SO4. The final product is extracted by drying under vacuum to remove any remaining and purified via prep-TLC eluting with a methanol and dichloromethane solution.

[0312] Compounds of Formula I wherein Rl is an acetoxy substituted alkyl can be synthesized by reaction of the compound of formula (5) with a solution containing acetylglycolic acid in methylene chloride. The reaction is stirred at approximately 50 C to 80 C for 1 to 4 hours.

The compound of Formula I can them be collected and purified using conventional techniques such as solvent removal followed by column chromatography.

Alternative Preparation - Secondary Modification of R1 [0313] It will be appreciated that secondary modification may be made to the R1 moiety after the compound of Formula I has been made. In one such case, a Formula I
compound having a terminal acetoxy group can be reacted with a base such as LiOH in a polar solvent such as methanol to provide the analogous hydroxy derivative.

Utility Testing and Administration [0314] The present invention relates to compounds, pharmaceutical compositions and methods of using the compounds and pharmaceutical compositions for the treatment and/or prevention of diseases mediated by SCD. The methods and pharmaceutical compositions are particularly suitable for use in the treatment of diseases related to dyslipidemia and disorders of lipid metabolism, especially diseases related to elevated plasma and tissue lipid levels, such as cardiovascular disease, diabetes, obesity, metabolic syndrome, fatty liver diseases and the like.
[0315] In general, the compounds of the invention find utility in the treatment of a patient for, or protecting a patient from developing, a disease related to dyslipidemia and/or a disorder of lipid metabolism, wherein lipid levels in an animal, especially a human being, are outside the normal range (i.e., abnormal lipid level, such as elevated plasma or tissue lipid levels), preferably where said lipid is a fatty acid, such as a free or complexed fatty acid, triglycerides, phospholipids, wax esters, or cholesterol, such as where VLDL, hepatic or peripheral tissue triglycerides are elevated, or any combination of these, where said lipid-related condition or disease is an SCD-mediated disease or condition such as metabolic syndrome, diabetes, non-alcoholic fatty liver disease, obesity, cancer, oily skin and related diseases, comprising administering to an animal, such as a mammal, especially a human patient, a therapeutically effective amount of a compound of the invention or a pharmaceutical composition comprising a compound of the invention wherein the compound inhibits the activity of SCD.

[0320] SCD-mediated diseases or conditions relating to hypertriglyceridemia, include but are not limited to, hyperlipoproteinemias, familial histiocytic reticulosis, lipoprotein lipase deficiency, apolipoprotein deficiency (such as ApoCII deficiency or ApoE
deficiency), and the like, or hypertriglyceridemia of unknown or unspecified etiology.

[0321] Metabolic syndrome and Syndrome X are also within the scope of the term "SCD-mediated disease" including all of the various component condition that make up the syndromes such as, but not limited to, dyslipidemia, low HDL, obesity, insulin resistance, decreased glucose tolerance, hypertension, microalbuminemia, hyperuricaemia, and hypercoagulability, diabetes, non-insulin-dependent diabetes mellitus, Type I diabetes, Type II

Inflammation, sinusitis, asthma, pancreatitis, osteoarthritis, rheumatoid arthritis, cystic fibrosis, and pre-menstrual syndrome may also be considered SCD-mediated diseases or conditions as may diseases or conditions which is, or is related to cancer, neoplasia, malignancy, metastases, tumors (benign or malignant), carcinogenesis, hepatomas and the like. SCD-mediated diseases or conditions also include diseases or conditions which are, or are related to, neurological diseases, psychiatric disorders, multiple sclerosis, eye diseases, and immune disorders. An SCD-mediated disease or condition also includes a disease or condition which is, or is related to, viral diseases or infections.

[03251 An SCD-mediated disease or condition also includes a condition where increasing lean body mass or lean muscle mass is desired, such as is desirable in enhancing performance through muscle building. Myopathies and lipid myopathies such as camitine palmitoyltransferase deficiency (CPT I or CPT II) are also included herein.
Such treatments are useful in humans and in animal husbandry, including for administration to bovine, porcine or avian domestic animals or any other animal to reduce triglyceride production and/or provide leaner meat products and/or healthier animals.

Testing [03261 The identification of compounds of the invention as SCD inhibitors was readily accomplished using the SCD enzyme and microsomal assay procedure described in Talamo and Bloch (1969) Analytical Biochemistry 29:300-304. When tested in this assay, compounds of the invention had less than 5 0% remaining SCD activity at 10 M concentration of the test compound, preferably less than 40% remaining SCD activity at 10 sM
concentration of the test compound, more preferably less than 30% remaining SCD activity at 10 M
concentration of the test compound, and even more preferably less than 20% remaining SCD
activity at 10 M
concentration of the test compound, thereby demonstrating that the compounds of the invention are potent inhibitors of SCD activity.

[0327] Other methods of testing the compounds disclosed herein are also readily available to those skilled in the art. Thus, in addition, testing of the compounds may be accomplished in vivo. In one such embodiment, testing of the compounds is accomplished by administering the compound to an animal afflicted with a plasma or tissue, fatty acid or triglyceride (TG) related disorder or very low density lipoprotein (VLDL)-related disorder and subsequently detecting a change in plasma or tissue fatty acid composition or triglyceride level in said animal thereby identifying a therapeutic agent useful in treating a plasma or tissue, fatty acid or triglyceride (TG) related disorder or very low density lipoprotein (VLDL)-related disorder.
In such embodiment, the animal may be a human, such as a human patient afflicted with such a disorder and in need of treatment of said disorder.

[0328] In specific embodiments of such in vivo processes, said change in SCD
activity in said animal is a decrease in activity, preferably wherein said SCD modulating agent does not substantially directly inhibit the biological activity of a AS desaturase, A6 desaturase, or fatty acid synthetase or other lipogenic enzymes.

[0329] The model systems useful for compound evaluation may include, but not limited to, the use of liver microsomes, such as from mice or rats that have been maintained on a high carbohydrate or high-fate diet, or from human donors, including persons suffering from obesity.
Immortalized cell lines, such as HepG2 (from human liver), MCF-7 (from human breast cancer) and 3T3-L1 (from mouse adipocytes) may also be used. Primary cell lines, such as primary hepatocytes and adipocytes, are also useful in testing the compounds of the invention. Where whole animals are used, mice or rats used as a source of primary hepatocyte cells may also be used wherein the mice or rats have been maintained on a high carbohydrate or other SCD
inducing diet to increase SCD activity in microsomes and/or to elevate plasma triglyceride levels or A9 fatty acid desaturation indexes (i.e., the 18:1/18:0 ratio);
alternatively mice on a normal diet or mice with normal triglyceride levels may be used. Mouse models employing transgenic mice designed for hypertriglyceridemia are also available. Rabbits, hamsters, and monkeys are also useful as animal models, especially those with diabetic and obesity.

[0330] Another suitable method for determining the in vivo efficacy of the compounds of the invention is to indirectly measure their impact on inhibition of SCD enzyme by measuring changes in fatty acid composition. These include absolute or relative reductions in SCD
product fatty acids such as 16:1 n-7, 18:1 n-7 or 18:1 n-9. As well fatty acid composition data may also be used to determine a subject's A9 Desaturation Index after administration of the compound. "Desaturation Index(s)" as employed in this specification means the ratio of the product over the substrate for the SCD enzyme as measured from a given tissue sample. This may be calculated using different equations, such as 18: In-9/18:0; 16:ln-7/16:0; and/or (16:ln-7+18:ln-7)/16:0. Desaturation Index(s) maybe measured in plasma or tissues as well as specific lipid classes containing fatty acids such as triglycerides and phospholipids.
Administration [0331] The compounds of Formula I may be administered in either single or multiple doses by any of the accepted modes of administration of agents having similar utilities, for example as described in those patents and patent applications incorporated by reference, including buccal, intranasal, intra-arterial injection, intravenously, intraperitoneally, parenterally, intramuscularly, subcutaneously, orally, or as an inhalant.

[0332] Oral administration is the preferred route for administration of the compounds of Formula I. Administration may be via capsule or enteric coated tablets, or the like. In making the pharmaceutical compositions that include at least one compound of Formula I, the active ingredient is usually diluted by an excipient and/or enclosed within such a carrier that can be in the form of a capsule, sachet, paper or other container. When the excipient serves as a diluent, in can be a solid, semi-solid, or liquid material (as above), which acts as a vehicle, carrier or medium for the active ingredient. Thus, the compositions can be in the form of tablets, pills, powders, lozenges, sachets, cachets, elixirs, suspensions, emulsions, solutions, syrups, aerosols (as a solid or in a liquid medium), ointments containing, for example, up to 10% by weight of the active compound, soft and hard gelatin capsules, sterile injectable solutions, and sterile packaged powders.

[0333] Some examples of suitable excipients include lactose, dextrose, sucrose, sorbitol, mannitol, starches, gum acacia, calcium phosphate, alginates, tragacanth, gelatin, calcium silicate, microcrystalline cellulose, polyvinylpyrrolidone, cellulose, sterile water, syrup, cyclodextrins, and methyl cellulose. The formulations can additionally include: lubricating agents such as talc, magnesium stearate, and mineral oil; wetting agents;
emulsifying and suspending agents; preserving agents such as methyl- and propylhydroxy-benzoates;
sweetening agents; and flavoring agents.

[0334] The compositions of the invention can be formulated so as to provide quick, sustained or delayed release of the active ingredient after administration to the patient by employing procedures known in the art. Controlled release drug delivery systems for oral administration include osmotic pump systems and dissolutional systems containing polymer-coated reservoirs or drug-polymer matrix formulations. Examples of controlled release systems are given in U.S.
Patent Nos. 3,845,770; 4,326,525; 4,902514; and 5,616,345.

[0335] Another formulation for use in the methods of the present invention employs transdermal delivery devices ("patches"). Such transdermal patches may be used to provide continuous or discontinuous infusion of the compounds of the present invention in controlled amounts. The construction and use of transdermal patches for the delivery of pharmaceutical agents is well known in the art. See, e.g., U.S. Patent Nos. 5,023,252, 4,992,445 and 5,001,139. Such patches may be constructed for continuous, pulsatile, or on demand delivery of pharmaceutical agents.

[0336] SCD inhibitors such as the compounds of Formula I are effective over a wide dosage range and is generally administered in a pharmaceutically effective amount.
Typically, for oral administration, each dosage unit contains from 1 mg to 2 g of an SCD
inhibitor, more commonly from 1 to 700 mg, and for parenteral administration, from 1 to 700 mg of a stearoyl-CoA desaturase inhibitor, more commonly about 2 to 200 mg. It will be understood, however, that the amount of the SCD inhibitor actually administered will be determined by a physician, in the light of the relevant circumstances, including the condition to be treated, the chosen route of administration, the actual compound administered and its relative activity, the age, weight, and response of the individual patient, the severity of the patient's symptoms, and the like.
[0337] For preparing solid compositions such as tablets, the principal active ingredient is mixed with a pharmaceutical excipient to form a solid preformulation composition containing a homogeneous mixture of a compound of the present invention. When referring to these preformulation compositions as homogeneous, it is meant that the active ingredient is dispersed evenly throughout the composition so that the composition may be readily subdivided into equally effective unit dosage forms such as tablets, pills and capsules.

[0338] The tablets or pills of the present invention may be coated or otherwise compounded to provide a dosage form affording the advantage of prolonged action, or to protect from the acid conditions of the stomach. For example, the tablet or pill can comprise an inner dosage and an outer dosage component, the latter being in the form of an envelope over the former. The two components can be separated by an enteric layer that serves to resist disintegration in the stomach and permit the inner component to pass intact into the duodenum or to be delayed in release. A variety of materials can be used for such enteric layers or coatings, such materials including a number of polymeric acids and mixtures of polymeric acids with such materials as shellac, cetyl alcohol, and cellulose acetate.

[0339] Compositions for inhalation or insufflation include solutions and suspensions in pharmaceutically acceptable, aqueous or organic solvents, or mixtures thereof, and powders.
The liquid or solid compositions may contain suitable pharmaceutically acceptable excipients as described supra. Preferably the compositions are administered by the oral or nasal respiratory route for local or systemic effect. Compositions in preferably pharmaceutically acceptable solvents may be nebulized by use of inert gases. Nebulized solutions may be inhaled directly from the nebulizing device or the nebulizing device may be attached to a face mask tent, or intermittent positive pressure breathing machine. Solution, suspension, or powder compositions may be administered, e.g. orally or nasally, from devices that deliver the formulation in an appropriate manner.

[0340] The following examples are included to demonstrate preferred embodiments of the invention. It should be appreciated by those of skill in the art that the techniques disclosed in the examples which follow represent techniques discovered by the inventor to function well in the practice of the invention, and thus can be considered to constitute preferred modes for its practice. However, those of skill in the art should, in light of the present disclosure, appreciate that many changes can be made in the specific embodiments which are disclosed and still obtain a like or similar result without departing from the spirit and scope of the invention.

When the reaction is substantially complete, the product of formula (23) is isolated by conventional means, for example by organic phase separation using aqueous KOH
followed by removal of the solvent under reduced pressure and drying under high vacuum.
