PRIORITY TO RELATED APPLICATIONS

     FIELD OF THE INVENTION 
       [0002]    The invention relates to inhibitors of 11β-hydroxysteroid dehydrogenase. The inhibitors include, for example, thiazoles and derivatives thereof and are useful for the treatment of diseases such as type II diabetes mellitus and metabolic syndrome. 
         [0003]    All documents cited or relied upon below are expressly incorporated herein by reference. 
       BACKGROUND OF THE INVENTION 
       [0004]    Diabetes mellitus is a serious illness that affects an increasing number of people across the world. Its incidence is escalating parallel to the trend of greater obesity in many countries. The serious consequences of the disease include increased risk of stroke, heart disease, kidney damage, blindness, and amputation. Diabetes is characterized by decreased insulin secretion and/or an impaired ability of peripheral tissues to respond to insulin, resulting in increased plasma glucose levels. There are two forms of diabetes: insulin-dependent and non-insulin-dependent, with the great majority of diabetics suffering from the non-insulin-dependent form of the disease, known as type 2 diabetes or non-insulin-dependent diabetes mellitus (NIDDM). Because of the serious consequences, there is an urgent need to control diabetes. 
         [0005]    Treatment of NIDDM generally starts with weight loss, a healthy diet and an exercise program. These factors are especially important in addressing the increased cardiovascular risks associated with diabetes, but they are generally ineffective in controlling the disease itself. There are a number of drug treatments available, including insulin, metformin, sulfonylureas, acarbose, and thiazolidinediones. However, each of these treatments has disadvantages, and there is an ongoing need for new drugs to treat diabetes. 
         [0006]    Metformin is an effective agent that reduces fasting plasma glucose levels and enhances the insulin sensitivity of peripheral tissue. Metformin has a number of effects in vivo, including an increase in the synthesis of glycogen, the polymeric form in which glucose is stored [De Fronzo, R. A. Drugs 1999, 58 Suppl. 1, 29]. Metformin also has beneficial effects on lipid profile, with favorable results on cardiovascular health—treatment with metformin leads to reductions in the levels of LDL cholesterol and triglycerides [Inzucchi, S. E. JAMA 2002, 287, 360]. However, over a period of years, metformin loses its effectiveness [Turner, R. C. et al. JAMA 1999, 281, 2005] and there is consequently a need for new treatments for diabetes. 
         [0007]    Thiazolidinediones are activators of the nuclear receptor peroxisome-proliferator activated receptor-gamma. They are effective in reducing blood glucose levels, and their efficacy has been attributed primarily to decreasing insulin resistance in skeletal muscle [Tadayyon, M. and Smith, S. A. Expert Opin. Investig. Drugs 2003, 12, 307]. One disadvantage associated with the use of thiazolidinediones is weight gain. 
         [0008]    Sulfonylureas bind to the sulfonylurea receptor on pancreatic beta cells, stimulate insulin secretion, and consequently reduce blood glucose levels. Weight gain is also associated with the use of sulfonylureas [Inzucchi, S. E. JAMA 2002, 287, 360] and, like metformin, they lose efficacy over time [Turner, R. C. et al. JAMA 1999, 281, 2005]. A further problem often encountered in patients treated with sulfonylureas is hypoglycemia [Salas, M. and Caro, J. J. Adv. Drug React. Tox. Rev. 2002, 21, 205-217]. 
         [0009]    Acarbose is an inhibitor of the enzyme alpha-glucosidase, which breaks down disaccharides and complex carbohydrates in the intestine. It has lower efficacy than metformin or the sulfonylureas, and it causes intestinal discomfort and diarrhea which often lead to the discontinuation of its use [Inzucchi, S. E. JAMA 2002, 287, 360] 
         [0010]    Because none of these treatments is effective over the long term without serious side effects, there is a need for new drugs for the treatment of type 2 diabetes. 
         [0011]    The metabolic syndrome is a condition where patients exhibit more than two of the following symptoms: obesity, hypertriglyceridemia, low levels of HDL-cholesterol, high blood pressure, and elevated fasting glucose levels. This syndrome is often a precursor of type 2 diabetes, and has high prevalence in the United States estimated at 24% (E. S. Ford et al. JAMA 2002, 287, 356). A therapeutic agent that ameliorates the metabolic syndrome would be useful in potentially slowing or stopping the progression to type 2 diabetes. 
         [0012]    In the liver, glucose is produced by two different processes. The first is gluconeogenesis, where new glucose is generated in a series of enzymatic reactions from pyruvate; and the second is glycolysis, where glucose is generated by the breakdown of the polymer glycogen. 
         [0013]    Two of the key enzymes in the process of gluconeogenesis are phosphoenolpyruvate carboxykinase (PEPCK) which catalyzes the conversion of oxalacetate to phosphoenolpyruvate, and glucose-6-phosphatase (G6Pase) which catalyzes the hydrolysis of glucose-6-phosphate to give free glucose. The conversion of oxalacetate to phosphoenolpyruvate, catalyzed by PEPCK, is the rate-limiting step in gluconeogenesis. On fasting, both PEPCK and G6Pase are upregulated, allowing the rate of gluconeogenesis to increase. The levels of these enzymes are controlled in part by the corticosteroid hormones (cortisol in human and corticosterone in mouse). When the corticosteroid binds to the corticosteroid receptor, a signaling cascade is triggered which results in the upregulation of these enzymes. 
         [0014]    The corticosteroid hormones are found in the body along with their oxidized 11-dehydro counterparts (cortisone and 11-dehydrocorticosterone in human and mouse, respectively), which do not have activity at the glucocorticoid receptor. The actions of the hormone depend on the local concentration in the tissue where the corticosteroid receptors are expressed. This local concentration can differ from the circulating levels of the hormone in plasma, because of the actions of redox enzymes in the tissues. The enzymes that modify the oxidation state of the hormones are 11beta-hydroxysteroid dehydrogenases forms I and II. Form I (11β-HSD1) is responsible for the reduction of cortisone to cortisol in vivo, while form II (11β-HSD2) is responsible for the oxidation of cortisol to cortisone. The enzymes have low homology and are expressed in different tissues. 11β-HSD1 is highly expressed in a number of tissues including liver, adipose tissue, and brain, while 11β-HSD2 is highly expressed in mineralocorticoid target tissues, such as kidney and colon. 11β-HSD2 prevents the binding of cortisol to the mineralocorticoid receptor, and defects in this enzyme have been found to be associated with the syndrome of apparent mineralocorticoid excess (AME). 
         [0015]    Since the binding of the 11β-hydroxysteroids to the corticosteroid receptor leads to upregulation of PEPCK and therefore to increased blood glucose levels, inhibition of 11β-HSD1 is a promising approach for the treatment of diabetes. In addition to the biochemical discussion above, there is evidence from transgenic mice, and also from small clinical studies in humans, that confirm the therapeutic potential of the inhibition of 11β-HSD1. 
         [0016]    Experiments with transgenic mice indicate that modulation of the activity of 11β-HSD1 could have beneficial therapeutic effects in diabetes and in the metabolic syndrome. For example, when the 11β-HSD1 gene is knocked out in mice, fasting does not lead to the normal increase in levels of G6Pase and PEPCK, and the animals are not susceptible to stress- or obesity-related hyperglycemia. Moreover, knockout animals which are rendered obese on a high-fat diet have significantly lower fasting glucose levels than weight-matched controls (Y. Kotolevtsev et al. Proc. Natl. Acad. Sci. USA 1997, 94, 14924). 11β-HSD1 knockout mice have also been found to have improved lipid profile, insulin sensitivity, and glucose tolerance (N. M. Morton et al. J. Biol. Chem. 2001, 276, 41293). The effect of overexpressing the 11β-HSD1 gene in mice has also been studied. These transgenic mice displayed increased 11β-HSD1 activity in adipose tissue, and they also exhibit visceral obesity which is associated with the metabolic syndrome. Levels of the corticosterone were increased in adipose tissue, but not in serum, and the mice had increased levels of obesity, especially when on a high-fat diet. Mice fed on low-fat diets were hyperglycemic and hyperinsulinemic, and also showed glucose intolerance and insulin resistance (H. Masuzaki et al. Science, 2001, 294, 2166). 
         [0017]    The effects of the non-selective 11β-hydroxysteroid dehydrogenase inhibitor carbenoxolone have been studied in a number of small trials in humans. In one study, carbenoxolone was found to lead to an increase in whole body insulin sensitivity, and this increase was attributed to a decrease in hepatic glucose production (B. R. Walker et al. J. Clin. Endocrinol. Metab. 1995, 80, 3155). In another study, decreased glucose production and glycogenolysis in response to glucagon challenge were observed in diabetic but not healthy subjects (R. C. Andrews et al. J. Clin. Endocrinol. Metab. 2003, 88, 285). Finally, carbenoxolone was found to improve cognitive function in healthy elderly men and also in type 2 diabetics (T. C. Sandeep et al. Proc. Natl. Acad. Sci USA 2004, 101, 6734). 
         [0018]    A need exists in the art, therefore, for 11β-HSD1 inhibitors that have efficacy for the treatment of diseases such as, for example, type II diabetes mellitus and metabolic syndrome. Further, a need exists in the art for 11β-HSD1 inhibitors having IC50 values less than about 1 μM.

         [0062]    “Pharmaceutically acceptable salt” refers to conventional acid-addition salts or base-addition salts that retain the biological effectiveness and properties of the compounds of formula I and are formed from suitable organic or inorganic acids or organic or inorganic bases. Sample acid-addition salts include those derived from inorganic acids such as hydrochloric acid, hydrobromic acid, hydroiodic acid, sulfuric acid, sulfamic acid, phosphoric acid and nitric acid, and those derived from organic acids such asp-toluenesulfonic acid, salicylic acid, methanesulfonic acid, oxalic acid, succinic acid, citric acid, malic acid, lactic acid, fumaric acid, and the like. Sample base-addition salts include those derived from ammonium, potassium, sodium and, quaternary ammonium hydroxides, such as for example, tetramethylammonium hydroxide. The chemical modification of a pharmaceutical compound (i.e. drug) into a salt is a well known technique which is used in attempting to improve properties involving physical or chemical stability, e.g., hygroscopicity, flowability or solubility of compounds. See, e.g., H. Ansel et. al., Pharmaceutical Dosage Forms and Drug Delivery Systems (6th Ed. 1995) at pp. 196 and 1456-1457. 
         [0063]    “Pharmaceutically acceptable ester” refers to a conventionally esterified compound of formula I having a carboxyl group, which esters retain the biological effectiveness and properties of the compounds of formula I and are cleaved in vivo (in the organism) to the corresponding active carboxylic acid. Examples of ester groups which are cleaved (in this case hydrolyzed) in vivo to the corresponding carboxylic acids are those in which the hydrogen is replaced with lower alkyl which is optionally substituted, e.g., with heterocycle, cycloalkyl, etc. Examples of substituted lower alkyl esters are those in which lower alkyl is substituted with pyrrolidine, piperidine, morpholine, N-methylpiperazine, etc. The group which is cleaved in vivo may be, for example, ethyl, morpholino ethyl, and diethylamino ethyl. In connection with the present invention, —CONH 2  is also considered an ester, as the —NH 2  may be cleaved in vivo and replaced with a hydroxy group, to form the corresponding carboxylic acid. 
         [0064]    Further information concerning examples of and the use of esters for the delivery of pharmaceutical compounds is available in Design of Prodrugs. Bundgaard H. ed. (Elsevier, 1985). See also, H. Ansel et. al., Pharmaceutical Dosage Forms and Drug Delivery Systems (6th Ed. 1995) at pp. 108-109; Krogsgaard-Larsen, et. al., Textbook of Drug Design and Development (2d Ed. 1996) at pp. 152-191. 
         [0065]    In the practice of the method of the present invention, an effective amount of any one of the compounds of this invention or a combination of any of the compounds of this invention or a pharmaceutically acceptable salt or ester thereof, is administered via any of the usual and acceptable methods known in the art, either singly or in combination. The compounds or compositions can thus be administered orally (e.g., buccal cavity), sublingually, parenterally (e.g., intramuscularly, intravenously, or subcutaneously), rectally (e.g., by suppositories or washings), transdermally (e.g., skin electroporation) or by inhalation (e.g., by aerosol), and in the form or solid, liquid or gaseous dosages, including tablets and suspensions. The administration can be conducted in a single unit dosage form with continuous therapy or in a single dose therapy ad libitum. The therapeutic composition can also be in the form of an oil emulsion or dispersion in conjunction with a lipophilic salt such as pamoic acid, or in the form of a biodegradable sustained-release composition for subcutaneous or intramuscular administration. 
         [0066]    Useful pharmaceutical carriers for the preparation of the compositions hereof, can be solids, liquids or gases; thus, the compositions can take the form of tablets, pills, capsules, suppositories, powders, enterically coated or other protected formulations (e.g. binding on ion-exchange resins or packaging in lipid-protein vesicles), sustained release formulations, solutions, suspensions, elixirs, aerosols, and the like. The carrier can be selected from the various oils including those of petroleum, animal, vegetable or synthetic origin, e.g., peanut oil, soybean oil, mineral oil, sesame oil, and the like. Water, saline, aqueous dextrose, and glycols are preferred liquid carriers, particularly (when isotonic with the blood) for injectable solutions. For example, formulations for intravenous administration comprise sterile aqueous solutions of the active ingredient(s) which are prepared by dissolving solid active ingredient(s) in water to produce an aqueous solution, and rendering the solution sterile. Suitable pharmaceutical excipients include starch, cellulose, glucose, lactose, talc, gelatin, malt, rice, flour, chalk, silica, magnesium stearate, sodium stearate, glycerol monostearate, sodium chloride, dried skim milk, glycerol, propylene glycol, water, ethanol, and the like. The compositions may be subjected to conventional pharmaceutical additives such as preservatives, stabilizing agents, wetting or emulsifying agents, salts for adjusting osmotic pressure, buffers and the like. Suitable pharmaceutical carriers and their formulation are described in Remington&#39;s Pharmaceutical Sciences by E. W. Martin. Such compositions will, in any event, contain an effective amount of the active compound together with a suitable carrier so as to prepare the proper dosage form for proper administration to the recipient. 
         [0067]    The pharmaceutical preparations can also contain preserving agents, solubilizing agents, stabilizing agents, wetting agents, emulsifying agents, sweetening agents, coloring agents, flavoring agents, salts for varying the osmotic pressure, buffers, coating agents or antioxidants. They can also contain other therapeutically valuable substances, including additional active ingredients other than those of formula I. 
         [0068]    The “therapeutically effective amount” or “dosage” of a compound according to this invention can vary within wide limits and may be determined in a manner known in the art. Such dosage will be adjusted to the individual requirements in each particular case including the specific compound(s) being administered, the route of administration, the condition being treated, as well as the patient being treated. In general, in the case of oral or parenteral administration to adult humans weighing approximately 70 kg, a daily dosage of from about 0.01 mg/kg to about 50 mg/kg should be appropriate, although the upper limit may be exceeded when indicated. The dosage is preferably from about 0.3 mg/kg to about 10 mg/kg per day. A preferred dosage may be from about 0.70 mg/kg to about 3.5 mg/kg per day. The daily dosage can be administered as a single dose or in divided doses, or for parenteral administration it may be given as continuous infusion. 
         [0069]    The compounds of the present invention can be prepared by any conventional manner. Suitable processes for synthesizing these compounds are provided in the examples. Generally, compounds of formula I can be prepared according to the Schemes described below. The sources of the starting materials for these reactions are also described. 
         [0070]    In the schemes below, the substituent at the 2-position of the thiazole ring is often drawn as a substituted phenyl moiety. It will be apparent to one of ordinary skill in the art that similar reactions are possible in the case of 2-heterocyclyl-thiazoles and in some cases, 2-alkyl-thiazoles. Drawing the structures with substituted phenyl substituents was useful for illustrative purposes, and does not limit the scope of the invention.

         [0071]    The coupling of carboxylic acids of structure 1 with amines of structure 2, according to Scheme 1, can be achieved using methods well known to one of ordinary skill in the art. For example, the transformation can be carried out by reaction of carboxylic acids of structure 1 or of appropriate derivatives thereof such as activated esters, with amines of diverse structure or their corresponding acid addition salts (e.g., the hydrochloride salts) in the presence, if necessary, of a coupling agent, many examples of which are well known per se in peptide chemistry. The reaction is conveniently carried out by treating the carboxylic acid of structure 1 with the hydrochloride of the reacting amine in the presence of an appropriate base, such as diisopropylethylamine, a coupling agent such as O-(benzotriazol-1-yl)-1,1,3,3-tetramethyluronium hexafluorophosphate, and in the optional additional presence of a substance that increases the rate of the reaction, such as 1-hydroxybenzotriazole or 1-hydroxy-7-azabenzotriazole, in an inert solvent, such as a chlorinated hydrocarbon (e.g., dichloromethane) or N,N-dimethylformamide or N-methylpyrrolidinone, at a temperature between about 0° C. and about room temperature, preferably at about room temperature. Alternatively, the reaction can be carried out by converting the carboxylic acid of formula 1 to an activated ester derivative, such as the N-hydroxysuccinimide ester, and subsequently reacting this with an amine or its corresponding acid addition salt. This reaction sequence can be carried out by reacting the carboxylic acid of formula 1 with N-hydroxysuccinimide in the presence of a coupling agent such as N,N′-dicyclohexylcarbodiimide in an inert solvent such as tetrahydrofuran at a temperature between about 0° C. and about room temperature. Alternatively, the N-hydroxysuccinimide ester can be prepared by reaction of commercially available 2-aryl-thiazole-5-carboxylic acids of formula 1 with TSTU (N,N,N′,N′-Tetramethyl-O—(N-succinimidyl)uronium tetrafluoroborate, CAS #105832-38-0, available from Aldrich Chemical Company, Milwaukee, Wis.). The reaction is conveniently carried out in the presence of an organic base such as triethylamine or diisopropylethylamine. The reaction can be carried out in polar solvents such as mixtures of DMF and dioxane according to the solubility of the carboxylic acid. The reaction can be carried out at a temperature between about 0° C. and about room temperature, preferably at around room temperature. This chemistry can be carried out either in the synthesis of a single compound or in the synthesis of libraries of compounds using automated parallel synthesis methods. 
         [0072]    Alternatively, compounds of formula 2 can be prepared by converting the carboxylic acid of formula 1 to the corresponding acyl halide, preferably the acid chloride, and then reacting this with an amine of formula HNR2R3, in the presence of base, preferably di-isopropylethyl amine, in an inert solvent such as dichloromethane or N,N-dimethylformamide. Acyl chlorides can be conveniently formed by reaction of carboxylic acids of structure 1 with chlorinating reagents, such as thionyl chloride or oxalyl chloride, preferably the latter, in dry dichloromethane at a temperature between about 0° C. and about room temperature. 
         [0073]    Commercially available 2-aryl-thiazole-4-carboxylic acids include the following

The 2-aryl-thiazole-4-carboxylic acids are then formed by saponification of the ethyl esters, for example by treatment with lithium hydroxide in a mixture of tetrahydrofuran and water.

         [0078]    For example, thiobenzamides (3) can be made from benzoic acids of formula 6 as shown above. The amidation of a benzoic acids can be accomplished by activation of the carboxylic acid conveniently by treating it with a chlorinating agent such as thionyl chloride or phosphorus oxychloride or phosphorus pentachloride, in the optional additional presence of a catalytic amount of N,N-dimethylformamide, at a temperature between about 0° C. and about 80° C. depending on the reactivity of the chlorinating agent followed by treatment with ammonium hydroxide. The resultant benzamide (7) is then treated with P 4 S 10 . This method is reported in Collection of Czechoslovak Chemical Communications, 55(11), 2722-30; 1990.

         [0079]    Alternatively, aryl-thiocarboxamides of formula 3 can be made by treatment of aryl nitrites in inert solvent with hydrogen sulfide or bis-(trimethylsilyl)sulfide as shown in Scheme 5 by heating the mixture at a temperature between about 70° C. and about 100° C. Aryl nitrites are available from a variety of different transformations known to those of skill in the art, such as those outlined in “Comprehensive Organic Transformations: A Guide to Functional Group Preparations” [R. C. Larock, VCH Publishers, Inc., N.Y. 1989, pages 861-862, 976-977, and 991-993] and in “Advanced Organic Chemistry” [J. March, 3 rd  Edition, Wiley Interscience, NY, 1985].

         [0080]    2-Aryl-thiazole-5-carboxylic acids of formula 5 can also be prepared as shown in Scheme 6 by coupling of 2-bromo-thiazole-4-carboxylic acid ethyl ester (8, R=Et, CAS #100367-77-9, coupling reactions conditions. The conditions of this method are disclosed in many publications which have been reviewed by A. Suzuki in an article entitled “The Suzuki reaction with arylboron compounds in arene chemistry” in  Modern Arene Chemistry  2002, 53-106. In carrying out this reaction any of the conditions conventional in a Suzuki reaction can be utilized. 
         [0081]    Generally these reactions are carried out in the presence of a metal catalyst such as a palladium catalyst utilizing any conventional organic solvent and a weak inorganic base. Among the preferred organic solvents are non-polar aprotic solvents, e.g. xylene or toluene, or polar aprotic solvents, e.g. dimethoxyethane. The weak inorganic base can be a carbonate or bicarbonate or phosphate or hydroxide, such as potassium carbonate, cesium carbonate, potassium phosphate or sodium hydroxide. As will be clear to one of skill in the art of organic synthesis, carrying out the reaction in the presence of sodium hydroxide will also lead to saponification of the ester. The source of palladium can be a palladium(0) complex (e.g., tetrakis(triphenylphosphine)palladium(0)) or a compound which can be reduced in situ to give palladium(0) (for example, palladium(II) acetate or bis(triphenylphosphine)palladium(II) chloride or Pd(dppf)Cl 2 ), and the reaction can be carried out in the optional additional presence of a catalytic amount of a phosphine ligand, for example tri-o-tolylphosphine or tri-tert-butylphosphine. The reaction is carried out at a temperature between about room temperature and about 100° C., and preferably about 90° C. 
         [0082]    As will be clear to one of skill in the art of organic synthesis, the Stille or Negishi reactions can in many cases be used in place of the Suzuki reaction. Information on the Stille reaction can be found in an article by M. Kosugi and K. Fugami in  Handbook of Organopalladium Chemistry for Organic Synthesis;  E.-I. Negishi, Ed.; John Wiley &amp; Sons, Inc., Hoboken, N.J., 2002, pages 263-283. For example, the reaction can be conveniently carried out by reacting a compound of formula 8 with a compound of formula Ar-M where M represents SnMe 3  or SnBu 3 , in a convenient inert solvent such as dioxane, in the presence of a catalytic amount of a palladium(0) complex (e.g., tetrakis(triphenylphosphine)palladium(0)) or a compound which can be reduced in situ to give palladium(0) (for example, palladium(II) acetate or bis(triphenylphosphine)palladium(II) chloride), in the presence of a catalytic amount of a phosphine ligand, for example tri-o-tolylphosphine, at a temperature about 100° C. Another alternative is to use the Negishi reaction whereby a compound of formula 8 is treated with an organozinc reagent of formula Ar—ZnBr in a convenient inert solvent such as tetrahydrofuran, in the presence of a catalytic amount of a palladium(0) complex (e.g., tetrakis(triphenylphosphine)palladium(0)) or Cl 2 Pd(dppf)-CH 2 Cl 2 ), at a temperature about 65° C. Suitable reaction conditions can be found in the literature, for example in J. A. Miller and R. P Farrell  Tetrahedron Lett.  1998, 39, 6441-6444; and in K. J. Hodgetts and M. T. Kershaw  Org. Lett.  2002, 4, 1363-1365.

         [0083]    Alternatively, compounds of structure 2 can be prepared as shown in Scheme 7 by hydrolyzing an ester of formula 8, coupling the resulting carboxylic acid of formula 11 with an amine of formula HNR2R3, and then carrying out a Suzuki reaction on the amide of formula 12. As will be evident to one of skill in the art, a Stille reaction or Negishi reaction as mentioned above can be used in place of a Suzuki reaction. The ester hydrolysis can be conveniently effected by treating the compound of formula 8 where R′=Et with one equivalent of an alkali metal hydroxide, such as potassium hydroxide, sodium hydroxide, or lithium hydroxide, preferably lithium hydroxide, in a suitable solvent, such as a mixture of tetrahydrofuran, methanol, and water. The reaction can be carried out at a temperature between about 0° C. and about 70° C., preferably at about 65° C. The coupling of the acid of formula 11 with an amine of formula HNR2R3 can be carried out using conditions described above in connection with Scheme 1. A further example of a coupling agent which is convenient for this coupling reaction is PyBrop (bromotripyrrolidinophosphonium hexafluorophosphate, CAS #132705-51-2, available from Fluka Chemical Corp., Milwaukee, Wis.). The Suzuki reaction is conveniently carried out as described above in relation to Scheme 6.

         [0085]    Phenyl boronic acids and boronic esters useful in the preparation of compounds of formula 2 may be commercially available or can be made by reactions that are well known in the field of organic synthesis, such as those outlined below. Phenyl boronic acids and phenyl boronic esters are formed by treatment of aryl halides (13) with organo lithium reagents such as n-butyl lithium followed by treatment with boron triisopropoxide or 4,4,4′,4′,5,5,5′,5′-octamethyl-2,2′-bi-1,3,2-dioxaborolane, followed by acidic work-up as is well known to those skilled in the art.

       EXAMPLES 
       [0088]    Reagents were purchased from Aldrich, Sigma, Bachem Biosciences, Advanced ChemTech, Lancaster and Argonaut Argogel and used without further purification. Unless otherwise indicated, all reagents were obtained from commercial sources. LC/MS (liquid chromatography/mass spectroscopy) spectra were recorded using the following system. For measurement of mass spectra the system was configured with a Micromass Platform II: API Ionization in positive electrospray (mass range: 150-1200 amu). The simultaneous chromatographic separation was achieved with the following HPLC system: Column, ES Industries Chromegabond WR C-18 3u 120 Å (3.2×30 mm) Cartridge; Mobile Phase A: Water (0.02% TFA) and Phase B: Acetonitrile (0.02% TFA); gradient 10% B to 90% B in 3 minutes; equilibration time, 1 minute; flow rate of 2 mL /minute. 
         [0089]    Compounds were purified using various methods of chromatography including flash column chromatography using silica gel and eluting with ethyl acetate and hexane solvent mixtures or other appropriate solvents. Certain compounds were also purified by reversed phased HPLC, using methods well known to those skilled in the art.

       Parallel Library Synthesis Method 
       [0100]    Commercially available primary and secondary amines at 0.3 molar concentration in DMF were prepared. Separately prepared were solutions of hydroxysuccinimde esters at 0.3 molar concentration in DMF. Using a multi-channel automated liquid handling system (TECAN Int.) 0.25 mL of the amine solutions were arrayed on a microtitre plate. To corresponding wells were added 0.25 mL of the hydroxysuccinimde ester solutions. To the reaction mixture of each well was added 0.15 mL of a triethylamine solution in DMF at 1.0 molar concentration. The reaction plates were sealed and shaken at room temperature overnight. At this time, the solutions in each well of the reaction plates were concentrated to remove volatile solvents at room temperature using a Genevac centrifugal evaporation system. The residue in each well was worked up using a multi-channel automated liquid handling system such as that made by TECAN to perform a dichloromethane-water liquid-liquid extraction. The desired compounds were obtained in the dichloromethane layer. From the dichloromethane layer, aliquots were removed for analysis by a LC-MS system. Subsequently, dichloromethane was removed using a centrifugal evaporation system.

Dry DMF (5 mL) was added subsequently with extreme caution over 10 minutes. After the gas evolution ceased, the mixture was stirred for another 30 minutes. The mixture was evaporated to dryness under reduced pressure. Then dry toluene was added to the residue and evaporated again to dryness under highly reduced pressure. The resultant product was used for the next step without further purification. 
       Step 3. Preparation of Amide 
       [0105]    A 1.0 M solution of 2-(2,3-dichloro-phenyl)-thiazole-4-carbonyl chloride (11.7 g, 40 mmol) in 40 mL dichloromethane was prepared, and 0.2 mL of such solution (0.2 mmol) was distributed to reaction tubes with a TECAN automated liquid handler. Then separate 0.5 M solutions of each reacting amine in dichloromethane (DCM) were prepared, and 0.4 mL of each solution was added with TECAN automated liquid handler to the above reaction tubes cooled in an ice-water bath. 1.0 M DIPEA (0.8 mL, 0.8 mmol) in DCM was added to each tube in the ice-water bath. After stirring in the ice-water bath for 30 minutes, the reaction mixture was stirred for another 4 hours at room temperature.

The combined organic extracts were washed with water (250 mL) and brine (250 mL). The combined organic extracts were dried over MgSO 4 , filtered and then concentrated in vacuo to give a mixture of 2-iodo-thiazole-4-carboxylic acid ethyl ester and 2-bromo-thiazole-4-carboxylic acid (11.5 g). This material was used in the next step without further purification. 
       Step 3. (2-Iodo-thiazol-4-yl)-(2-methyl-piperidin-1-yl)-methanone 
       [0129]    A solution of a mixture of 2-iodo-thiazole-4-carboxylic acid ethyl ester and 2-bromo-thiazole-4-carboxylic acid (from Step 2; 11.5 g), N,N-dimethylaminopyridine (11.2 g, 91.7 mmol), HOBT (10.0 g, 74.0 mmol), 1-(3-dimethylaminopropyl)-3-ethyl-carbodiimide hydrochloride (14.0 g, 73.0 mmol), and 2-methyl-piperidine (8 mL, 68.1 mol) in dry dichloromethane (150 mL) and dry acetonitrile (20 mL) was stirred at room temperature for 72 h. At this time, the reaction mixture was concentrated in vacuo. The resulting solution was diluted with dichloromethane (25 mL) and 1 N HCl (250 mL). The mixture was stirred for several hours at room temperature. At this time, the mixture was filtered and the solids were washed with dichloromethane (200 mL). The aqueous layer was extracted with dichloromethane (2×250 mL). The combined organic layers were washed with water (450 mL) and brine (450 mL). The organic layer was dried over MgSO 4 , filtered, concentrated in vacuo, and purified by flash column chromatography eluting with a gradient of ethyl acetate in hexanes to give (2-iodo-thiazol-4-yl)-(2-methyl-piperidin-1-yl)-methanone (8.1 g, 30% yield from 2-amino-thiazole-4-carboxylic acid ethyl ester hydrobromide). 
       Step 4. [2-(2-Methoxy-phenyl)-thiazol-4-yl]-(2-methyl-piperidin-1-yl)-methanone 
       [0130]    A mixture of (2-iodo-thiazol-4-yl)-(2-methyl-piperidin-1-yl)-methanone (Step 3; 200 mg, 0.59 mmol), 2-methoxyphenylboronic acid (Combi-Blocks, Inc., San Diego, Calif.; 135 mg, 0.89 mmol), potassium carbonate (201 mg, 1.45 mmol), and PdCl 2 dppf (Strem Chemicals, Inc., Newburyport, Mass.; 22 mg, 0.03 mmol) in dimethoxyethane (3 mL) in a scintillation vial was heated at ˜78° C. for 72 h with shaking. The reaction mixture was cooled to room temperature, concentrated in vacuo using a Genevac evaporator, and purified using automated mass-directed LC-MS purification.

     Testing of Compounds of the Invention 
       [0135]    The in vitro inhibition of 11β-HSD1 by compounds of the present invention was demonstrated as follows: 
         [0136]    Purified human HSD1 was diluted in 50 mM Tris-HCl, 100 mM NaCl, 0.1 mg/mL BSA, 0.02% Lubrol, 20 mM MgCl2, 10 mM glucose 6-phosphate, 0.4 mM NADPH, 60 U/mL glucose 6-phosphate dehydrogenase to a concentration of 1.5 μg/mL (Enzyme Solution). Cortisone (100 μM) in DMSO was diluted to 1 μM with 50 mM Tris-HCl, 100 mM NaCl (Substrate Solution). Test compounds (40 μM) in DMSO were diluted 3 fold in series in DMSO and further diluted 20 fold in Substrate Solution. Enzyme Solution (10 μL/well) was added into 384 well microtiter plates followed by diluted compound solutions (10 μL/well) and mixed well. Samples were then incubated at 37° C. for 30 min. EDTA/biotin-cortisol solution (10 μL/well) in 28 mM EDTA, 100 nM biotin-cortisol, 50 mM Tris-HCl, 100 mM NaCl was then added followed by 5 μL/well of anti-cortisol antibody (3.2 μg/mL) in 50 mM Tris-HCl, 100 mM NaCl, 0.1 mg/mL BSA and the solution was incubated at 37° C. for 30 min. Five μL per well of Eu-conjugated anti-mouse IgG (16 nM) and APC-conjugated streptavidin (160 nM) in 50 mM Tris-HCl, 100 mM NaCl, 0.1 mg/mL BSA was added and the solution was incubated at room temperature for 2 hours. Signals were quantitated by reading time-resolved fluorescence on a Victor 5 reader (Wallace). 
         [0137]    Percent inhibition of HSD1 activity by an agent at various concentrations was calculated by the following formula: 
         [0000]      % Inhibition=100*[1−( Fs−Fb )/( Ft−Fb )], 
         [0000]    wherein:
       Fs is the fluorescence signal of the sample which included the agent,   Fb is the fluorescence signal in the absence of HSD1 and agent,   Ft is the fluorescence signal in the presence of HSD1, but no agent.       
 
         [0141]    The inhibitory activities of test compounds were determined by the IC 50 s, or the concentration of compound that gave 50% inhibition. 
         [0142]    Results obtained by the foregoing test using a representative number of compounds of formula I as the test compounds are shown in the following table:
