FIELD OF THE INVENTION
This invention relates to compounds that modulate the activity of liver X receptors (LXRs). The invention also provides pharmaceutical compositions comprising the compounds of the invention and methods of using those compositions, for example, for the treatment and/or prophylaxis of coronary heart disease, atherosclerosis, heart failure, and related cardiovascular diseases. In particular, pyrazole isomers and derivatives are provided for modulating the activity of LXRs.
BACKGROUND OF THE INVENTION
Blood cholesterol is a major risk factor for coronary heart disease (CHD) due to the central role that cholesterol metabolism plays in the disease. Circulating low density lipoprotein (LDL) is modified through oxidation in vascular tissue. Macrophages in the subendothelial space take up these cholesterol-rich particles and accumulate large quantities of cholesteryl esters and pro-inflammatory lipids, thereby becoming foam cells. This sets up a chronic inflammatory process in the arterial wall involving macrophages, other inflammatory cells, cytokines, and smooth muscle cells, followed by disruption of the arterial endothelial surface, vessel narrowing, and ultimately thrombosis and vessel occlusion resulting in myocardial infarction (MI). Lowering circulating LDL decreases the uptake of oxidized LDL by macrophages, thereby limiting this pathological process. Statins decrease risk for CHD by lowering LDL. In addition to cholesterol delivery mechanisms mediated by LDL, there is a cholesterol removal process termed reverse cholesterol transport (RCT) in which excess cholesterol in peripheral tissues is trafficked back to the liver where it is secreted via the bile into the intestine, and excreted in feces (Cuchel, M., Rader, D. J. (2006). Circulation 113(21): 2548-2555). The transfer of cholesterol to the liver takes place, in part, on high density lipoprotein (HDL) and this key role in RCT is one of the main reasons why HDL cholesterol (HDL-C) is often the lipid risk factor most closely correlated with CHD in epidemiologic studies. i.e. HDL-C has a strong inverse correlation with disease risk (Gordon, D. J. et al., (1989). Circulation 79(1):8-15; Duffy D. & Rader D. J. (2009). Nat Rev Cardiol 6 (7):455-63). In addition, HDL has anti-oxidant activity that inhibits the generation of pro-inflammatory oxidized LDL.
The removal of cholesterol from atherosclerotic lesions is thought to attenuate the disease process and, thus, stimulating RCT is likely to be a beneficial therapeutic modality. This is a major rationale for developing LXR agonists for the treatment of atherosclerosis. LXRs (α and β isoforms) are master regulators of cellular and whole-body RCT controlling the transcription of genes involved in all major phases of movement of peripheral cellular cholesterol to the liver and out of the body.
LXRs are able to sense excess intracellular cholesterol by binding to and being transactivated by specific oxysterol cholesterol metabolites. Upon activation, LXRs induce the expression of a variety of cholesterol efflux transporters, apolipoproteins, and lipoprotein modification pathways in multiple tissues that facilitate the removal of excess cellular and whole-body cholesterol (Fiévet C, Staels B. (2009). Biochem Pharmacol. 77(8): 1316-27). It is anticipated that such an integrated stimulus of foam cell macrophage cholesterol efflux, trafficking in the circulation, uptake and metabolism in the liver, and excretion in feces will have a robust anti-atherosclerosis effect.
Two important target genes that are induced by LXR agonists in a variety of tissues, including foam cell macrophages, are the ABC transporters ABCA1 and ABCG1. These are lipid efflux transporters that pump cholesterol out of the cell onto HDL acceptors, generating HDL-C. They play a critical role in helping macrophage foam cells efflux excess sterol (Jessup, W., I. C. Gelissen, et al. (2006). Curr Opin Lipidol 17(3): 247-57). LXR agonists also induce apolipoprotein E in macrophages (Laffitte, B. A., J. J. Repa, et al. (2001). Proc Natl Acad Sci USA. 98(2): 507-12.) which also helps to promote cholesterol efflux from these cells. HDL-C can be taken up directly by the liver or the cholesterol can be first transferred to LDL via the cholesteryl ester transfer protein (CETP) and be delivered to the liver through the LDL receptor. LXRs also induce CETP expression in liver and adipose tissue (Luo, Y. and A. R. Tall (2000). J Clin Invest. 105(4): 513-20.), which could facilitate RCT flux via the LDL pathway. Excess hepatic cholesterol can be converted to bile acids or secreted directly into the bile for subsequent excretion. The liver secretion and intestinal excretion steps are also stimulated by LXR agonists through the induction of two additional ABC transporters, ABCG5 and ABCG8 (Repa, J. J., K. E. Berge, et al. (2002). J Biol Chem. 277(21): 18793-800). These transporters pump cholesterol out of the hepatocyte into bile and also limit absorption of cholesterol by transporting enterocyte cholesterol into the lumen of the gut.
LXRs also inhibit the NF-κB-dependent induction in macrophages of a variety of inflammatory genes such as iNOS, COX-2 and IL-6 among others (Joseph, S. B., A. Castrillo, et al. (2003). Nat Med. 9(2): 213-9), and LXR agonists inhibit inflammatory processes in vitro and in vivo. Recent studies also suggest that synthetic LXR agonists could affect acquired immunity by limiting T-cell proliferative responses to activating signals (Bensinger, S. J., M. N. Bradley, et al. (2008). Cell 134(1), 97-111). These effects on innate and acquired immunity are additional potential anti-atherosclerotic mechanisms of LXR agonists.
LXRs also have favorable effects on glucose homeostasis. Treatment of diabetic mouse models with LXR agonists results in the inhibition of hepatic PGC-1, PEPCK, and glucose-6 phosphatase (G6Pase) and the stimulation of hepatic glucokinase, resulting in marked inhibition of hepatic glucose output (HGO) (Laffitte, B. A., L. C. Chao, et al. (2003). Proc Natl Acad Sci USA. 100(9): 5419-24). In addition, GLUT4 expression in adipose tissue is upregulated by LXR agonism, thereby increasing peripheral glucose disposal. Consistent with this, LXR agonist treatment of cultured adipocytes increased glucose uptake. Finally, LXR agonism appears to downregulate glucocorticoid action in liver. LXR agonists inhibit hepatic 113-HSD1 expression (Stulnig, T. M., U. Oppermann, et al. (2002). Diabetes. 51(8): 2426-33), an enzyme that converts inactive cortisone to active corticosterone, thus likely lowering liver glucocorticoid. This downregulation of hepatic glucocorticoid activity is likely the mechanism for LXR regulation of PEPCK, G-6-Pase, and glucokinase. Thus, by both inhibiting hepatic glucose output and stimulating peripheral glucose disposal, LXR treatment markedly lowers plasma glucose in diabetic rodent models.
Recently LXRs have also been shown to be important regulators of prostate cancer cell survival. Disruption of lipid rafts in response to LXR-dependent cholesterol efflux (Dufour J. et al. (2012). Curr Opin Pharmacol. 2012 Jul. 19). Lowering membrane cholesterol results in a suppression of the AKT survival pathway and consequently apoptosis. Thus, stimulating the LXR-AKT pathway may be beneficial for prostate cancer. Similarly, LXR activation has been suggested to have utility in treating a variety of other cancers including those of the breast (Vedin, L-L. et al., (2009) Carcinogenesis. 30 (4): 575-79) and pancreas (Rasheed et al., (2012) Cancer Research. 72 (8), Supplement 1, Abstract 3494).
LXR agonists have also been suggested to be useful for the prevention and treatment of photo and chronological skin aging, through their positive effects on keratinocyte and fibroblast gene expression (Chang, K. C. et al., (2008) Mol Endocrinol. 22(11): 2407-19).
In addition to the positive effects on cholesterol metabolism, LXRs stimulate fatty acid and triglyceride (TG) synthesis in the liver, primarily through inducing the transcription factor SREBP-1c. Consequently, most LXR agonists cause at least some degree of undesirable accumulation of lipids within hepatocytes and elevated plasma TG and LDL (Groot, P. H., et al. (2005). J Lipid Res. 46(10): 2182-91), a property primarily attributed to LXRα specific activity (Peet, D. J., et al. (1998). Cell. 93(5): 693-704; Lund, E. G., et al. (2006). Biochem Pharmacol. 71(4): 453-63). This is the major mechanism-based adverse effect of the target class and is most pronounced in full pan agonists. Strategies to minimize the undesirable lipid effects include identifying LXRβ selective compounds that are also partial agonists. Partial agonists can display tissue-specific activation or repression of nuclear receptors (Albers, M., et al. (2006). J Biol Chem. 281(8): 4920-30), as was demonstrated for the anti-estrogen tamoxifen, which functions as an antagonist of estrogen signaling in breast tissue and an agonist in the uterus (Delmas, P. D., et al. (1997). N Engl J Med 337(23): 1641-1647). Characterization of LXR isoform-specific null mice indicates that LXRα is the predominant mediator of LXR activity in the liver Peet, D. J., et al. (1998). Cell. 93(5): 693-704; Lund, E. G., et al. (2006). Biochem Pharmacol. 71(4): 453-63). In macrophages, however, LXRβ alone is sufficient to mediate the effects of LXR ligands on target gene expression. Therefore, compounds with limited LXRα activity should have anti-atherogenic activity while limiting unwanted hepatic effects.
Liver X Receptors
LXRs are adopted orphan members of the nuclear receptor superfamily. There are two LXR isoforms, LXRα and LXRβ, and both heterodimerize with the Retinoid X Receptor (RXR) (Song, C., et al. (1994). Proc Natl Acad Sci USA. 91(23): 10809-13; Apfel, R., et al. (1994). Mol Cell Biol. 14(10): 7025-35; Willy, P. J., et al. (1995). Genes Dev. 9(9): 1033-45). Both LXRs, when complexed with RXR, bind to distinct regions of DNA called LXR response elements (LXREs) present in the promoters of LXR target genes. The LXR response elements take the form of two degenerate hexad direct repeat sequences, the consensus being AGGTCA, separated by 4 nucleotides, collectively termed a DR4 repeat (Willy, P. J. and D. J. Mangelsdorf (1997). Genes Dev. 11(3): 289-98). LXRα is found predominantly in the liver, with lower levels found in kidney, intestine, spleen and adrenal tissue (see, e.g., Willy, et al. (1995) Genes Dev. 9(9):1033-1045). LXRβ is ubiquitous in mammals and was found in nearly all tissues examined.

The various compounds described herein, or their pharmaceutically acceptable salts, may contain one or more asymmetric centers and may thus give rise to isomers, such as enantiomers, diastereomers, and other stereoisomeric forms. Such forms may be defined, in terms of absolute stereochemistry, as (R)- or (S)-, or as (D)- or (L)- for amino acids. The present invention is meant to include all such possible individual stereoisomers and mixtures thereof, including their racemic and optically pure enantiomeric or diastereomeric forms. The compounds are normally prepared as racemates and can conveniently be used as such, or optically active (+) and (−), (R)- and (S)-, or (D)- and (L)-isomers or corresponding diastereomers may be prepared using chiral synthons or chiral reagents, or they may be resolved from racemic mixtures using conventional techniques, such as chiral chromatography or reverse phase HPLC. When the compounds described herein contain olefinic double bonds or other centers of geometric asymmetry, and unless specified otherwise, it is intended that the compounds include both E and Z geometric isomers.
The invention also includes isotopically-labeled compounds of the invention, wherein one or more atoms is replaced by an atom having the same atomic number, but an atomic mass or mass number different from the atomic mass or mass number usually found in nature. Examples of isotopes suitable for inclusion in the compounds of the invention include isotopes of hydrogen, such as 2H or D and 3H or T, carbon such as 11C, 13C, and 14C, chlorine, such as 36Cl, fluorine such as 18F, iodine, such as 123I and 125I, nitrogen, such as 13N and 15N, oxygen, such as 15O, 17O, and 18O, phosphorus, such as 32P, and sulfur, such as 35S. Certain isotopically-labeled compounds of the invention, for example, those incorporating a radioactive isotope, are useful in drug and/or substrate tissue distribution studies. The radioactive isotopes tritium, 3H, and carbon-14, 14C, are particularly useful for this purpose in view of their ease of incorporation and ready means of detection. Substitution with heavier isotopes such as deuterium, 2H or D, may afford certain therapeutic advantages resulting from greater metabolic stability, for example, increase in vivo half-life or reduced dosage requirements, and hence may be preferred in some circumstances. Substitution with positron emitting isotopes, such as 11C, 18F, 15O, and 13N, can be useful in Positron Emission Topography (PET) studies for examining substrate receptor occupancy.
Isotopically-labeled compounds of the invention can generally be prepared by conventional techniques known to those skilled in the art or by processes analogous to those described herein, using an appropriate isotopically-labeled reagent in place of the non-labeled reagent otherwise employed.
The present invention may be embodied in other specific forms without parting from the spirit or essential attributes thereof. This invention encompasses all combinations of aspects and/or embodiments of the invention noted herein. It is understood that any and all aspects or embodiments of the present invention may be taken in conjunction with any other aspect or embodiment or embodiments to describe additional embodiments. It is also understood that each individual element of the embodiments is its own independent embodiment. Furthermore, any element of an embodiment is meant to be combined with any and all other elements from any embodiment to describe an additional embodiment.

“Nuclear receptor” refers to a receptor that activates or represses transcription of one or more genes in the nucleus (but can also have second messenger signaling actions), typically in conjunction with other transcription factors. The nuclear receptor is activated by the natural cognate ligand for the receptor. Nuclear receptors are ordinarily found in the cytoplasm or nucleus, rather than being membrane-bound. A nuclear receptor is a member of a superfamily of regulatory proteins that are receptors for various endogenous small molecules, e.g., steroids, retinoids, vitamin D and thyroid hormones. These proteins bind to cis-acting elements in the promoters of their target genes and modulate gene expression in response to a ligand therefore. Nuclear receptors may be classified based on their DNA binding properties. For example, the glucocorticoid, estrogen, androgen, progestin and mineralocorticoid receptors bind as homodimers to hormone response elements (HREs) organized as inverted repeats. Another example are receptors, including those activated by retinoic acid, thyroid hormone, vitamin D3, fatty acids/peroxisome proliferators and ecdysone, that bind to HREs as heterodimers with a common partner, the retinoid X receptor (RXR). Among the latter receptors is LXR.

Diabetes mellitus, commonly called diabetes, refers to a disease process derived from multiple causative factors and characterized by elevated levels of plasma glucose, referred to as hyperglycemia. See, e.g., LeRoith, D. et al., (eds.), DIABETES MELLITUS (Lippincott-Raven Publishers, Philadelphia, Pa. U.S.A. 1996). Uncontrolled hyperglycemia is associated with increased and premature mortality due to an increased risk for macrovascular diseases, including nephropathy, neuropathy, retinopathy, hypertension, cerebrovascular disease and coronary heart disease. Therefore, control of glucose homeostasis is a critically important approach for the treatment of diabetes.
There are two major forms of diabetes: type 1 diabetes (formerly referred to as insulin-dependent diabetes or IDEM); and type 2 diabetes (formerly referred to as noninsulin dependent diabetes or NIDDM). Type 2 diabetes is a disease characterized by insulin resistance accompanied by relative, rather than absolute, insulin deficiency. Type 2 diabetes can range from predominant insulin resistance with relative insulin deficiency to predominant insulin deficiency with some insulin resistance. Insulin resistance is the diminished ability of insulin to exert its biological action across a broad range of concentrations. In insulin resistant individuals, the body secretes abnormally high amounts of insulin to compensate for this defect. When inadequate amounts of insulin are present to compensate for insulin resistance and adequate control of glucose, a state of impaired glucose tolerance develops. In a significant number of individuals, insulin secretion declines further and the plasma glucose level rises, resulting in the clinical state of diabetes. Type 2 diabetes can be due to a profound resistance to insulin stimulating regulatory effects on glucose and lipid metabolism in the main insulin-sensitive tissues: muscle, liver and adipose tissue. This resistance to insulin responsiveness results in insufficient insulin activation of glucose uptake, oxidation and storage in muscle and inadequate insulin repression of lipolysis in adipose tissue and of glucose production and secretion in liver. In Type 2 diabetes, free fatty acid levels are often elevated in obese and some non-obese subjects and lipid oxidation is increased.
Premature development of atherosclerosis and an increased rate of cardiovascular and peripheral vascular diseases are characteristic features of subjects with diabetes. Hyperlipidemia is an important precipitating factor for these diseases. Hyperlipidemia is a disorder generally characterized by an abnormal increase in serum lipids, e.g., cholesterol and triglyceride, in the bloodstream and is an important risk factor in developing atherosclerosis and heart disease. For a review of disorders of lipid metabolism, see, e.g., Wilson, J. et al., (ed.), Disorders of Lipid Metabolism, Chapter 23, Textbook of Endocrinology, 9th Edition, (W. B. Sanders Company, Philadelphia, Pa. U.S.A. 1998). Hyperlipidemia is usually classified as primary or secondary hyperlipidemia. Primary hyperlipidemia is generally caused by genetic defects, while secondary hyperlipidemia is generally caused by other factors, such as various disease states, drugs, and dietary factors. Alternatively, hyperlipidemia can result from both a combination of primary and secondary causes of hyperlipidemia. Elevated cholesterol levels are associated with a number of disease states, including coronary artery disease, angina pectoris, carotid artery disease, strokes, cerebral arteriosclerosis, and xanthoma.
Dyslipidemia, or abnormal levels of lipoproteins in blood plasma, is a frequent occurrence among diabetics, and has been shown to be one of the main contributors to the increased incidence of coronary events and deaths among diabetic subjects (see, e.g., Joslin, E. Ann. Chim. Med. (1927), Vol. 5, pp. 1061-1079). Epidemiological studies since then have confirmed the association and have shown a several-fold increase in coronary deaths among diabetic subjects when compared with non-diabetic subjects (see, e.g., Garcia, M. J. et al., Diabetes (1974), Vol. 23, pp. 105-11 (1974); and Laakso, M. and Lehto, S., Diabetes Reviews (1997), Vol. 5, No. 4, pp. 294-315). Several lipoprotein abnormalities have been described among diabetic subjects (Howard B., et al., Arteriosclerosis (1978), Vol. 30, pp. 153-162).
Further provided by this invention are methods of using the compounds of the invention to treat obesity, as well as the complications of obesity. Obesity is linked to a variety of medical disorders including diabetes and hyperlipidemia. Obesity is also a known risk factor for the development of type 2 diabetes (See, e.g., Barrett-Conner, E., Epidemol. Rev. (1989), Vol. 11, pp. 172-181; and Knowler, et al., Am. J Clin. Nutr. (1991), Vol. 53, pp. 1543-1551).

A pharmaceutical composition of the invention will contain a therapeutically effective amount of a compound of the invention, as an individual stereoisomer or mixture of stereoisomers, or a pharmaceutically acceptable salt thereof, with the remainder of the pharmaceutical composition comprised of one or more pharmaceutically acceptable excipients. Generally, for oral administration, a compound of the invention, as an individual stereoisomer or mixture of stereoisomers, or a pharmaceutically acceptable salt thereof will comprise from 1% to 99% by weight of a pharmaceutically acceptable composition, with the remainder of the composition comprised of one or more pharmaceutically acceptable excipients. Typically, a compound of the invention, as an individual stereoisomer or mixture of stereoisomers, or a pharmaceutically acceptable salt thereof will comprise from 5% to 75% by weight of a pharmaceutically acceptable composition, with the remainder of the composition comprised of one or more pharmaceutically acceptable excipients. For parenteral administration, a compound of the invention, as an individual stereoisomer or mixture of stereoisomers, or a pharmaceutically acceptable salt thereof will comprise from 0.01% to 1% by weight of a pharmaceutically acceptable composition. Methods for preparing the dosage forms of the invention are known, or will be apparent, to those skilled in this art; for example, see Remington's Pharmaceutical Sciences, 18th Ed., (Mack Publishing Company, Easton, Pa., 1990).
A therapeutically effective amount of a compound of the invention will vary depending upon a sundry of factors including the activity, metabolic stability, rate of excretion and duration of action of the compound, the age, weight, general health, sex, diet and species of the subject, the mode and time of administration of the compound, the presence of adjuvants or additional therapeutically active ingredients in a composition, and the severity of the disease for which the therapeutic effect is sought.
The compounds of the invention can be administered to human subjects at dosage levels in the range of about 0.1 to about 10,000 mg per day. A normal human adult having a body weight of about 70 kilograms can be administered a dosage in the range of from about 0.15 μg to about 150 mg per kilogram of body weight per day. Typically, a normal adult human will be administered from about 0.1 mg to about 25 mg, or 0.5 mg to about 10 mg per kilogram of body weight per day. The compounds of the invention may be administered in one or more unit dose forms. The unit doses may be administered one to four times a day, or two times a day, or once a day. In an alternate method of describing an effective dose, an oral unit dose is one that is necessary to achieve a blood serum level of about 0.05 to 20 μg/ml or about 1 to 20 μg/ml in a subject. The optimum dose of a compound of the invention for a particular subject can be determined by one of ordinary skill in the art.
Compounds of the invention, or an individual isomer or mixture of isomers or a pharmaceutically acceptable salt thereof, may also be administered simultaneously with, prior to, or after administration of one or more of the therapeutic agents described below. Such combination therapy includes administration of a single pharmaceutical dosage formulation which contains a compound of the invention and one or more additional active agents, as well as administration of the compound of the invention and each active agent in its own separate pharmaceutical dosage formulation. For example, a compound of the invention and an HMG-CoA reductase inhibitor can be administered to the subject together in a single oral dosage composition such as a tablet or capsule, or each agent administered in separate oral dosage formulations. Where separate dosage formulations are used, the compounds of the invention and one or more additional active agents can be administered at essentially the same time, i.e., concurrently, or at separately staggered times, i.e., sequentially; combination therapy is understood to include all these regimens.
In one embodiment, the compounds of the invention are used in combination with one or more of the following therapeutic agents in treating atherosclerosis: antihyperlipidemic agents, plasma HDL-raising agents, antihypercholesterolemic agents, cholesterol biosynthesis inhibitors (such as HMG CoA reductase inhibitors, such as lovastatin, simvastatin, pravastatin, fluvastatin, atorvastatin and rivastatin), acyl-coenzyme A: cholesterol acytransferase (ACAT) inhibitors, probucol, raloxifene, nicotinic acid, niacinamide, cholesterol absorption inhibitors, bile acid sequestrants (such as anion exchange resins, or quaternary amines (e.g., cholestyramine or colestipol)), low density lipoprotein receptor inducers, clofibrate, fenofibrate, benzofibrate, cipofibrate, gemfibrizol, vitamin B6, vitamin B12, anti-oxidant vitamins, β-blockers, anti-diabetes agents, angiotensin II antagonists, angiotensin converting enzyme inhibitors, platelet aggregation inhibitors, fibrinogen receptor antagonists, aspirin or fibric acid derivatives.
In another embodiment, the compounds of the invention are used in combination with one or more of the following therapeutic agents in treating cholesterol biosynthesis inhibitor, particularly an HMG-CoA reductase inhibitor. The term HMG-CoA reductase inhibitor is intended to include all pharmaceutically acceptable salt, ester, free acid and lactone forms of compounds which have HMG-CoA reductase inhibitory activity and, therefore, the use of such salts, esters, free acids and lactone forms is included within the scope of this invention. Compounds which have inhibitory activity for HMG-CoA reductase can be readily identified using assays well-known in the art. For instance, suitable assays are described or disclosed in U.S. Pat. No. 4,231,938 and WO 84/02131. Examples of suitable HMG-CoA reductase inhibitors include, but are not limited to, lovastatin (MEVACOR®; see, U.S. Pat. No. 4,231,938); simvastatin (ZOCOR®; see, U.S. Pat. No. 4,444,784); pravastatin sodium (PRAVACHOL®; see, U.S. Pat. No. 4,346,227); fluvastatin sodium (LESCOL®; see, U.S. Pat. No. 5,354,772); atorvastatin calcium (LIPITOR®; see, U.S. Pat. No. 5,273,995) and rivastatin (also known as cerivastatin; see, U.S. Pat. No. 5,177,080). The structural formulae of these and additional HMG-CoA reductase inhibitors that can be used in combination with the compounds of the invention are described at page 87 of M. Yalpani, “Cholesterol Lowering Drugs,” Chemistry & Industry, pp. 85-89 (5 Feb. 1996). In presently preferred embodiments, the HMG-CoA reductase inhibitor is selected from lovastatin and simvastatin.
In an additional embodiment, the compounds of the invention are used in combination with one or more of the following therapeutic agents in treating with one or more additional active diabetes agents depending on the desired target therapy (see, e.g., Turner, N. et al., Prog. Drug Res. (1998), Vol. 51, pp. 33-94; Haffner, S., Diabetes Care (1998), Vol. 21, pp. 160-178; and DeFronzo, R. et al. (eds.), Diabetes Reviews (1997), Vol. 5, No. 4). A number of studies have investigated the benefits of combination therapies with oral agents (see, e.g., Mahler, R., J. Clin. Endocrinol. Metab. (1999), Vol. 84, pp. 1165-71; United Kingdom Prospective Diabetes Study Group: UKPDS 28, Diabetes Care (1998), Vol. 21, pp. 87-92; Bardin, C. W. (ed.), Current Therapy In Endocrinology And Metabolism, 6th Edition (Mosby—Year Book, Inc., St. Louis, Mo. 1997); Chiasson, J. et al., Ann. Intern. Med. (1994), Vol. 121, pp. 928-935; Coniff, R. et al., Clin. Ther. (1997), Vol. 19, pp. 16-26; Coniff, R. et al., Am. J. Med. (1995), Vol. 98, pp. 443-451; Iwamoto, Y. et al., Diabet. Med. (1996), Vol. 13, pp. 365-370; Kwiterovich, P., Am. J. Cardiol (1998), Vol. 82 (12A), pp. 3U-17U). These studies indicate that diabetes and hyperlipidemia modulation can be further improved by the addition of a second agent to the therapeutic regimen.
In a further embodiment, the compounds of the invention are used in combination with one or more of the following therapeutic agents in treating in treating diabetes: sulfonylureas (such as chlorpropamide, tolbutamide, acetohexamide, tolazamide, glyburide, gliclazide, glynase, glimepiride, and glipizide), biguanides (such as metformin), thiazolidinediones (such as ciglitazone, pioglitazone, troglitazone, and rosiglitazone), and related insulin sensitizers, such as selective and non-selective activators of PPARα, PPARβ and PPARγ; dehydroepiandrosterone (also referred to as DHEA or its conjugated sulphate ester, DHEA-SO4); antiglucocorticoids; TNFα inhibitors; α-glucosidase inhibitors (such as acarbose, miglitol, and voglibose), pramlintide (a synthetic analog of the human hormone amylin), other insulin secretogogues (such as repaglinide, gliquidone, and nateglinide), insulin, as well as the therapeutic agents discussed above for treating atherosclerosis.

Example A
Scintillation Proximity Assay (SPA)
The SPA assay measures the radioactive signal generated by the binding of 3H-24,25-epoxycholesterol to LXRα-RXRα or LXRβ-RXRα heterodimers The basis of the assay is the use of SPA beads containing a scintillant, such that when binding to the receptor brings the labeled ligand into proximity with the bead, the energy from the label stimulates the scintillant to emit light. The light is measured using a standard microplate scintillation reader. The ability of a ligand to bind to a receptor can be measured by assessing the degree to which the compound can compete off a radiolabelled ligand with known affinity for the receptor.

Preparation of Protein Lysates
Baculovirus expression plasmids for human RXR α (accession No NM_002957), LXRα (accession No U22662), and LXRβ (accession No U07132) were made by cloning the appropriate full-length cDNAs into the pBacPakhis2 vector (Clontech, CA) following standard procedures. Insertion of the cDNAs into the pBAcPakhis2 vector polylinker created an in frame fusion to the cDNA to an N-terminal poly-His tag present in pBacPakhis1. Correct cloning was confirmed by restriction mapping, and/or sequencing.
Cell lysates were prepared by infecting healthy, Sf9 insect cells at a density of approximately 2.0×106/ml at 27° C., in a total volume of 1 L per 3 L sized shake flasks, cultured under standard conditions. To prepare the LXRα lysate, insect cells were co-infected with the recombinant viruses containing LXRα and RXRα in a ratio of 2:1. To prepare the LXRβ lysate, insect cells were co-infected with the recombinant viruses containing LXRβ and RXRα in a ratio of 2:1. In both cases cells were incubated for 68 hours at 27° C. with constant shaking prior to harvesting.
After incubation, cells were harvested by centrifugation and pelleted. Cell pellets were resuspended in 40 ml of freshly prepared ice-cold extraction buffer (20 mM Tris pH 8.0, 10 mM Imidazole, 400 mM NaCl, 10% glycerol, 0.1 mM DTT and EDTA free protease inhibitor tablet (Sigma Catalog No:S8830)), per 1 L culture.
Cells were homogenized slowly on ice using a Dounce homogenizer to achieve 80-90% cell lysis. The homogenate was centrifuged in a pre-chilled rotor (Ti50 or Ti70, or equivalent) at 45,000 rpm for 40 minutes at 4° C. Aliquots of the supernatant were frozen on dry ice and stored frozen at −80° C. until quantification and quality control.
Preparation of Screening Reagents
[3H]24,25 Epoxycholesterol (EC) solution: For a single 384-well plate, 52.26 μL of [3H] EC (specific activity 76 Ci/mmol, concentration 1 mCi/mL) was added to 4.5 mL of 2×SPA buffer to provide for a final concentration of 76.25 nM. For each additional 384-well plate, an additional 52.27 μL of [3H] EC was added to 4.5 mL of additional 2×SPA buffer. The final concentration of [3H] EC in the well was 25 nM.
LXRα lysate (prepared as above) was diluted with protein lysate dilution buffer. 9000 μL of diluted LXRα lysate was prepared per 384-well plate and 9000 μL of diluted LXRα lysate was prepared for each additional 384-well plate.
LXRβ lysate (prepared as above) was diluted with protein lysate dilution buffer. 9000 μL of diluted LXRβ lysate was prepared per 384-well plate and 9000 μL of diluted LXRβ lysate was prepared for each additional 384-well plate.
SPA bead solution: 4.5 mL of 2×SPA buffer w/o EDTA, 3.6 mL of H2O, and 0.9 mL of Ysi His-tag SPA beads (vortex well before taking) were mixed together to prepare 10% SPA bead solution for a 384-well plate involving LXR lysate. 4.5 mL of 2×SPA buffer w/o EDTA, 2.7 mL of H2O, and 1.8 mL of Ysi His-tag SPA beads (vortex well before taking) were mixed together to prepare 20% SPA bead solution for a 384-well plate involving LXRβ lysate.
Procedure:
Appropriate dilutions of each compound were prepared in a 384-well plate and pipetted into the appropriate wells of two 384 well plate at 1 μL per well.
20 μL of [3H] EC was added to each well of both 384 well plates.
20 μl of diluted LXRα lysate was added to each well of the first 384 well plate.
20 μL of diluted LXRβ lysate was added to each well of the second 384 well plate.
20 μL of 10% SPA bead solution was added to each well of first 384 well plate. 20 μL of 20% SPA bead solution was added to each well of second 384 well plate
The plates were covered with clear sealer, placed on a shaker (300 RPM) for 10 minutes then incubated at ambient temperature for 10 minutes and then spinned at 1000 RPM for 10 minutes at ambient temperature.
The Plates were analyzed using a luminescent plate reader (MicroBeta, Wallac) using the program projectAD 3H_384CPM. The setting for n projectAD 3H_384CPM was:
Counting Mode: CPM;
Sample Type: Top-read;
Count time: 1 minute.
Assays for LXRα and LXRβ were performed in the identical manner. The determined Ki represents the average of at least three independent dose response experiments. The binding affinity for each compound may be determined by non-linear regression analysis using the one site competition formula to determine the IC50 where:

Y=Bottom+(Top−Bottom)/(1+10X-log IC50).

The Ki is than calculated using the Cheng and Prusoff equation where:

Ki=IC50/(1+[Concentration of Ligand]/Kd of Ligand).

For this assay, typically the Concentration of Ligand=25 nM and the Kd of EC for the receptor is 200 nM as determined by saturation binding.
The compounds of the invention demonstrated the ability to bind to LXRβ and/or LXRα, when tested in this assay.
Example B
Co-Transfection Assay
To measure the ability of compounds to activate or inhibit the transcriptional activity of LXR in a cell based assay, the co-transfection assay was used. It has been shown that LXR functions as a heterodimer with RXR. For the co-transfection assay, expression plasmids for LXRα and LXRβ are introduced separately via transient transfection into mammalian cells along with a luciferase reporter plasmid that contains one copy of a DNA sequence that is bound by LXR-RXR heterodimers (LXRE; Willy, P. et. al. 1995). LXRs heterodimerize with the endogenous RXR. Treatment of transfected cells with an LXR agonist increases the transcriptional activity of LXR, which is measured by an increase in luciferase activity. Similarly, LXR antagonist activity can be measured by determining the ability of a compound to competitively inhibit the activity of a LXR agonist.
Required Materials
CV-1 African Green Monkey Kidney Cells
Co-transfection expression plasmids, comprising full-length LXRα (pCMX-h LXRα or LXRβ (pCMX-hLXRβ), reporter plasmid (LXREx1-Tk-Luciferase), and control (pCMX-Galactosidase expression vector) (Willey et al. Genes & Development 9 1033-1045 (1995)).
Transfection reagent such as FuGENE6 (Roche) or Transit 2020 (Mirus Bio)
1× cell lysis buffer:
22.4 mM Tricine pH 8.0
0.56 mM EGTA pH 8.0
5.6 mM MgSO4 
0.6% Triton X-100
5.6% glycerol
10× luciferase substrate solution:
10 mM HEPES pH 6.5
2.75 mM D-Luciferin
0.75 mM Coenzyme-A
3.7 mM ATP
96 mM DTT
Preparation of Screening Reagents
CV-1 cells were prepared 24 hours prior to the experiment by plating them into T-175 flasks or 500 cm2 dishes in order to achieve 70-80% confluency on the day of the transfection. The number of cells to be transfected was determined by the number of plates to be screened. Each well of a 384 well plate requires 1.5×104 cells. DNA Transfection Reagent was prepared by mixing the required plasmid DNAs with a cationic lipid transfection reagent Transit 2020 (Mirus Bio) for CV1 by following the instructions provided with the reagents. Optimal DNA amounts were determined empirically per cell line and size of vessel to be transfected. For each T175 cm2 flask a total of 44.4 ug for CV1 of DNA, 133 ul Transit2020 and 4.5 ml DMEM for CV1 was mixed and added. Cells were then incubated at least 5 hours at 37° C. to prepare screening cells.
Luciferase assay reagent was prepared by combining before use:
1 part of 10× Luciferase substrate solution
9 parts of 1× cell lysis buffer.
Procedure
Assay plates were prepared by dispensing 5 μL of compound per well of a 384 well plate to achieve final compound concentration of 10 μM and no more than 0.5% DMSO. Media was removed from the screening cells, the cells trypsinized, harvested cells by centrifugation, counted, and plated at a density of approximately 1.5×104 cells in the 384 well assay plate prepared above in a volume of about 95 uL. Assay plates containing both compounds and screening cells (100 μL in total volume) were incubated for 20 hours at 37° C.
After incubation with compounds, media was removed from the cells and luciferase assay reagent (30 μL/well) added. After  ̃2 minutes at ambient temperature, the assay plates were read on a luminometer (PE Biosystems Northstar reader with on-board injectors, or Envision (Perkin Elmer) or equivalent).
The LXR/LXRE co-transfection assay can be used to establish the EC50/IC50 values for potency and percent activity or inhibition for efficacy. Efficacy defines the activity of a compound relative to a high control ((N-(3-((4-fluorophenyl)-(naphthalene-2-sulfonyl)amino)propyl)-2,2-dimethylpropionamide)) or a low control (DMSO/vehicle). The dose response curves are generated from a 10 point curve with concentrations differing by 1⁄2 LOG units. Each point represents the average of 4 wells of data from a 384 well plate.
The data from this assay is fitted to the following equation, from which the EC50 value may be solved:

Y=Bottom+(Top−Bottom)/(1+10((log EC50-X)*HillSlope)).

The EC50/IC50 is therefore defined as the concentration at which an agonist or antagonist elicits a response that is halfway between the Top (maximum) and Bottom (baseline) values. The EC50/IC50 values represented are the averages of at least 2 and normally 3 independent experiments. The determination of the relative efficacy or % control for an agonist is by comparison to the maximum response achieved by ((N-(3-((4-fluorophenyl)-(naphthalene-2-sulfonyl)-amino)propyl)-2,2-dimethylpropionamide) that is measured individually in each dose response experiment.
Table 1 lists LXRβ EC50 values and % efficacy measurements in the cotransfection assay for examples of this invention.

Synthesis

The compounds of the present invention may be prepared in a number of methods well known to those skilled in the art, including, but not limited to those described below, or through modifications of these methods by applying standard techniques known to those skilled in the art of organic synthesis. The compounds were named using ChemBioDraw Ultra 12.0 (CambridgeSoft). The reagents and starting materials are commercially available, or readily synthesized by well-known techniques by one of ordinary skill in the arts. It is understood that in the following description, combinations of substituents and/or variables of the depicted formulae are permissible only if such contributions result in stable compounds. Unless otherwise indicated, all compounds associated with NMR and/or mass spectra data were prepared and the NMR and mass spectra measured.
INTERMEDIATES




Intermediates of the type I-1d can be prepared by treating an appropriately substituted 1-bromo-3-fluorobenzene (I-1a) with an appropriate base such as LHMDS followed by addition of a thiol reagent (RSNa) to afford I-1b. Oxidation to the sulfone can be achieved with m-CPBA affording I-1c. Subsequent treatment of the bromide with palladium boronylation conditions such as PdCl2(dppf), bis(pinacoloato)diboron and KOAc affords Intermediate I-1d. Modifications of this route known to one skilled in the art can be achieved to obtain various substituents at RD. For instance, reduction of a carboxylic acid with reagents such as BH3 in THF provides a methylalcohol. As well similar chemistry can be employed on pyridine systems to provide intermediates that are used to make compounds of the invention.

Intermediate 1a
Preparation of 4-bromo-2-fluoro-6-(methylthio)benzoic acid




To a 500 mL round bottom flask attached with condenser was added 4-bromo-2,6-difluorobenzoic acid (16.0 g, 67.5 mmol) and anhydrous THF (110 mL). The reaction flask was cooled in an ice bath prior to dropwise addition of 1.0 M LHMDS (74.0 mL, 1.1 equiv). The reaction suspension was stirred at rt for 20 min prior to addition of sodium thiomethoxide (5.21 g, 74.2 mmol). The reaction solution was allowed to stir at reflux for 3 hr. The reaction was determined to be complete after quenching a reaction aliquot in dilute aq. HCl and running GCMS: found m/z=265, 267 parent ions. The cooled reaction mixture was quenched with H2O and diluted with EtOAc (200 mL). The reaction mixture was transferred to a separatory funnel, and 1.0 N aq. HCl was added to give a pH=2-3 solution. The EtOAc layer was separated, washed with brine, dried over Na2SO4, and concentrated in vacuo to afford 14.6 g (81% yield) of the intermediate 6-fluoro-4-bromo-2-methylsulfanyl-benzoic acid as a waxy white solid. 1H NMR (400 MHz, CDCl3) δ 7.18 (s, 1H), 7.12 (dd, J=8 Hz, 1H), 2.49 (s, 3H); GCMS m/z=265, 267 [M]+. Alternatively, the intermediate 6-fluoro-4-bromo-2-methylsulfanyl-benzoic acid was prepared as follows:
To a 20 L flask was charged dimethyl formamide (14.5 L, 10.0 vol), followed by sodium hydroxide (294 g, 1.2 eq) and the reaction mass cooled to −15 to −10° C. 4-bromo-2,6-difluororbenzoic acid (1450 g, 1.0 equiv) was added over a period of 10-15 min at −15 to −10° C. and stirred for an additional 10-15 min. Sodium thiomethoxide (515 g, 1.2 equiv) was added over a period of 5-10 min at −10 to −5° C. On completion of the addition, the temperature of the reaction was raised to 25-28° C. over a period of 45 to 60 min and maintained at that temperature 1.5-2 h. The temperature of the reaction was then raised to 60-65° C. over a period of 30-60 min and maintained at 60-65° C. for 5 hrs until the reaction was deemed complete. The reaction mixture was then cooled to 20-25° C. and quenched with a cooled (5-10° C.) solution of 2N HCl (5.05 L of 12N HCl in 30.3 L water). Following the quench, EtOAc (14.5 L, 10 vol) was added and the mixture stirred for 10-15 min. The phases were separated and the aqueous layer was extracted with EtOAc (7.25 L, 5 vol). The two phases were separated and the combined organic layer was washed with a brine solution (725 g of NaCl in 3.63 L of water). The phases were separated and the organic layer was washed with water (7.25 L, 5 vol). The phases were separated and the organic layer was dried over sodium sulfate (1450 g). The organic layer was filtered to remove the sodium sulfate, which was then washed with EtOAc (2.90 L, 2 vol). The organic layer was concentrated under reduced pressure at 45-50° C./30-40 mm Hg to  ̃1 to 1.2 volumes and petroleum ether (7.25 L, 5 vol) was added at 40-45° C. over a period of 15-20 min. The solution was cooled to 20-25° C. over a period of 20-25 min. The solid was filtered and washed with petroleum ether (2.90 L, 2 vol) and the product dried under vacuum at 25-28° C., 0.4 to 0.7 mbar to afford 1410 g (87% yield, 99.4 Area %) of the intermediate 6-fluoro-4-bromo-2-methylsulfanyl-benzoic acid.

Preparation of (4-bromo-2-fluoro-6-(methylthio)phenyl)methanol




Into a N2 purged 500 mL round bottom flask attached with condenser was added 6-fluoro-4-bromo-2-methylsulfanyl-benzoic acid (14.6 g, 55.0 mmol) and anhydrous THF (70.0 mL). The reaction solution was allowed to cool to 0° C. prior to dropwise addition of a 1.0 M BH3-THF (83.0 mL, 1.5 equiv) solution in THF. The reaction solution was stirred at rt then at reflux for an additional 2 hr. The reaction solution was cooled prior to quenching with a 1:1 H2O/THF solution. The reaction solution was transferred to a separatory funnel with EtOAc (100 mL) and an aqueous solution of K2CO3 was added. The EtOAc phase was separated, washed with brine, dried over Na2SO4, and concentrated in vacuo. The crude product was purified by chromatography through a 110 g SiO2 column using a solvent gradient of 100% Hx to 55% EtOAc. The purified title product was obtained as a solid white wax (13.7 g, 99% yield). 1H NMR (400 MHz, CDCl3) δ 7.13 (s, 1H), 7.06 (dd, J1=8 Hz, J2=2 Hz, 1H), 4.77 (s, 2H), 2.51 (s, 3H), 2.20-2.05 (br s, 1H); GCMS m/z=251, 253 [M]+.
Alternatively, the intermediate (4-bromo-2-fluoro-6-(methylthio)phenyl)methanol was prepared as follows:
To a 20 L flask was charged 4-bromo-2-fluoro-6-(methylthio)benzoic acid (1400 g, 1.0 eq) followed by THF (14 L, 10 vol) under nitrogen. To this solution was added borane-dimethyl sulfide complex (800 g, 1000 mL) at 25-28° C. over a period of 30-45 min. The reaction temperature was raised to 60-65° C. over a period of 30-45 min and the temperature maintained until HPLC showed <1% of 4-bromo-2-fluoro-6-(methylthio)benzoic acid ( ̃3-4 hrs). On completion of the reaction the mixture was cooled to 10-15° C. over a period of 30-40 min. The reaction was then quenched with MeOH (2.1 L, 1.5 vol) over a period of 1 to 11⁄2 hrs at 10-15° C. The reaction mass was then concentrated under vacuum at 40-50° C./0.4 to 0.7 mbar to 1 to 1.5 volumes. The resultant mixture was dissolved in DCM (8.4 L, 6 vol). The organic layer was washed with an ammonium chloride solution (560 g NH4Cl in 2.8 L water, 2 vol). The phases were separated and the organic layer was washed with 10% NaHCO3 solution (2.8 L, 2 vol), saturated brine solution (2.1 L, 1.5 vol) and water (4.2 L, 3 vol). The organic layer was separated and dried over sodium sulfate (700 g). The sodium sulfate was removed by filtration and washed with DCM (2.8 L, 2 vol). The organic layer was concentrated under vacuum at 40-45° C./0.4 to 0.7 mbar to 1 to 1.2 vol to afford the product which was dried under vacuum at 45-50° C./0.4 to 0.7 mbar. The title product was obtained in 90% yield (1200 g) with 90.1 Area %.

Preparation of (4-bromo-2-fluoro-6-(methanesulfonyl)phenyl)-methanol




To a 500 mL flask was added (4-bromo-2-fluoro-6-(methylthio)phenyl)methanol (13.7 g, 54.6 mmol) and anhydrous DCM (125 mL). The solution was cooled to 0-3° C. in an ice bath prior to portion wise addition of 3-chloroperbenzoic acid (77% max., Aldrich) (18.8 g, 2 equiv). The reaction solution was then allowed to warm to rt where it remained for 18 hrs. The reaction was then concentrated in vacuo to remove DCM and the residue was washed into a separatory funnel with EtOAc and 1 M aq. NaOH. The EtOAc layer was separated, washed with 1 M aq NaOH, dried over Na2SO4, and concentrated in vacuo. The residue was purified by flash chromatography (Biotage, 65×200 mm SiO2 column, gradient elution from 100% Hx to 90% EtOAc/Hx). Appropriate fractions were combined and concentrated in vacuo to afford the title compound as a colorless, semi-crystalline solid, yield: 8.10 g (52%). 1H NMR (400 MHz, DMSO-d6) δ 7.98 (dd, J=8 Hz, 1H), 7.91 (s, 1H), 5.45 (t, J=8 Hz, 1H), 4.88 (dd, J1=8 Hz, J2=2 Hz, 2H), 3.42 (s, 3H); 19F NMR (400 MHz, DMSO-d6) δ −111.8 ppm; GCMS m/z=283, 285 [M]+.

Preparation of (2-fluoro-6-(methylsulfonyl)-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)methanol




To a 100 mL round bottom flask, purged with dry N2, was weighed (4-bromo-2-fluoro-6-(methanesulfonyl)phenyl)-methanol (1.98 g, 6.99 mmol), bis(pinacolato)diboron (2.13 g 1.2 equiv), dichloro[1,1′-bis(diphenylphosphino) ferrocene]palladium (II) DCM adduct (560 mg, 10 mol %), potassium carbonate (2.06 g, 3 equiv), and DMSO (25.0 mL). The resulting suspension was allowed to stir at 90° C. for 3 hrs. An aliquot of reaction solution was found to contain no more starting bromide as determined by LCMS analysis. The cooled reaction suspension was diluted with EtOAc (50 mL) and water (50 mL) and filtered through a Celite padded Buchner Funnel. The resulting filtrate was transferred to a separatory funnel, and the organic phase was separated. The aqueous phase was extracted with EtOAc, and the combined EtOAc phases were washed with brine, dried over Na2SO4, and concentrated in vacuo. The residue was purified by silica gel flash chromatography (Biotage SP-1, 40 g SiO2 column, gradient elution from 100% Hx to 60% EtOAc/Hx) to afford a clear viscous oil. The product was isolated as an amorphous white powder by dissolving in DCM and reprecipitation resulted upon addition of Hx. The title compound was isolated as a solid white powder, yield: 1.90 g (82% yield). 1H NMR (400 MHz, CDCl3) δ 8.28 (s, 1H), 7.79 (d, J=8 Hz, 1H), 5.03 (d, J=8 Hz, 2H), 3.23 (s, 3H) 3.05 (t, J=8 Hz, 1H), 1.35 (s, 6H); 19F NMR (400 MHz, CDCl3) δ −116.3 ppm.
Alternatively, the intermediate (2-fluoro-6-(methylsulfonyl)-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)methanol was prepared as follows: To a 500 mL jacketed reactor equipped with a stir bar, temperature probe, reflux condenser and a nitrogen inlet was charged methyl tetrahydrofuran (MeTHF) (75 mL, 5 volumes) followed by potassium acetate (5.2 g, 53 mmol, 1 equiv.) and (oxydi-2,1-phenylene)bis(diphenylphosphine) (320 mg; 600 μmoles, 0.011 equiv.) and bis(pinacolato)diboron (18 g, 69 mmol, 1.3 equiv.). The reaction flask was evacuated to less than 150 Torr, and then back filled with nitrogen. This degassing procedure was repeated 3 times. Pd(OAc)2 (94 mg; 420 μmoles, 0.0075 equiv.) was charged to the reactor and the reaction flask was evacuated to less than 150 Torr, and then back filled with nitrogen and the sequence repeated 3 times. The resulting slurry was allowed to age at 20-25° C. for 15 min. Upon completion of the 15 min age, the slurry was heated to an internal temperature of 80° C. As the mixture in the reactor was heating to temperature, in a separate flask was charged (4-bromo-2-fluoro-6-(methanesulfonyl)phenyl)-methanol (15 g, 53 mmol, 1 equiv.) followed by MeTHF (75 mL, 5 volumes). The resulting solution was degassed by bubbling nitrogen subsurface for not less than 15 min. prior to use. Once the catalyst mixture had reached reflux, the degassed solution of (4-bromo-2-fluoro-6-(methanesulfonyl)phenyl)-methanol in MeTHF was added to the reaction in a single portion and allowed to react. The reaction typically takes  ̃20 hrs to complete after the addition of substrate. Upon completion (typically <0.75 RAP of starting material the reaction was cooled to 20-25° C. Once at rt the reaction was diluted with MeTHF (75 mL, 5 volumes) and washed with a 5 wt % NaCl solution (7.5 volumes, 110 mL) for at least 15 min. The phases were separated and the upper product rich MeTHF stream was filtered through Celite to remove insoluble palladium residues. The Celite cake was washed with MeTHF (75 mL, 5 volumes). The reaction was treated with functionalized silica (30 equiv) to remove palladium and color. The slurry was agitated for at least 60 min and then filtered to remove the silica. The used silica was washed with MeTHF (5 volumes, 75 mL). The combined organic phase was washed with water (5 volumes, 75 mL). The organic was distilled to 5 volumes (75 mL) under vacuum (60-70 Torr, bath temp of 30° C.). When the 75 mL landmark was reached the distillation was stopped and heptane (75 mL, 5 volumes) was added dropwise to the reaction solution. After  ̃35 mL of heptanes had been added the product began to crystallize from the solution. On completion of the addition the product was isolated by filtration and the wet cake washed with MeTHF-heptanes (1:9) solution (2×75 mL) and dried at 50° C. The title product was obtained a white solid, 14 g, (78% yield) with 99.6 Area %.

EXAMPLES
Preparation of Compounds of the Invention




Particular embodiments of the invention include compounds exemplified by general structure 1-07 in Scheme 1. In general, pyrazole compounds of formula 1-07 can be synthesized following the methodology shown in Scheme 1. The aniline (1-01), which is purchased or prepared by methods known to one skilled in the art, is converted to the azide (1-02) using sodium nitrite and sodium azide under acidic conditions. The azide (1-02) reacts with the phosphorane (1-03) to yield the triazole (1-04). After formation of the enolate, the alkyl ketone (1-05) is alkylated with an appropriately substituted ester (R3COOEt) to give the 1,3-diketone (1-05). Reaction of the diketone (1-05) with an alkyl hydrazine sulfate under acidic conditions gives exclusively (or in some cases mainly) the desired regioisomer of the pyrazole (1-06). The minor isomer can be removed by silica gel column chromatography if necessary. Palladium mediated coupling between the aryl bromide (1-06) with the aryl boronic acid or ester derivatives produces 1-07.
Additional chemistry known to one skilled in the art can be carried out at the R3 position including reductions, grignard additions, alkylations, fluorinations, acylations, amidations, and heterocycle forming reactions to prepare compounds of the invention. For example, when R3 contains an ester (e.g. CF2COOEt or COOEt) additional functionalization can be carried out by one skilled in the art to make amides, as well as, primary, secondary and tertiary alcohols.

In general, pyrazole compounds of formula 2-06 can be prepared by the following methodology in Scheme 2. The alkyl ketone (1-04) can be heated with sodium methoxide and dimethyl oxalate to give the diketoester (2-01). Reaction of the diketone (2-01) with methyl hydrazine gives a majority of the desired pyrazole isomer (2-02) and a minor pyrazole isomer (2-03), and the isomers can be separated by column chromatography if necessary. A palladium mediate coupling with 2-02 and an appropriate boronic acid or boronate affords 2-04, which is hydrolyzed to the acid 2-05. Coupling of 2-05 to an appropriate amine provides compounds of formula 2-06.

Specific compounds in the invention contain an oxazole as represented by general structure 3-12. In general, the oxazole compounds of formula 3-12 can be synthesized following the methodology shown in Scheme 3. The methyl 4-bromo-2-methylbenzoate (3-01) is converted to the benzylic bromide (3-02) by reaction with NBS and AIBN in CCl4. The benzylic bromide (3-02) is displaced by 4-methoxyphenol under basic conditions to yield the biaryl ether compound, (3-03). The methyl ester (3-03) is transformed to the methyl ketone (3-04) by reaction with LHMDS and MeMgBr. Other alkyl functionality can be incorporated at this position by introduction of an appropriate Grignard reagent such as EtMgBr. The ketone (3-04) is reacted with a substituted ester (R3COOR) to provide the diketone (3-05). The diketone undergoes cyclization with a hydrazine to form the pyrazole (3-06). The alcohol protecting group is removed upon treatment with CAN, and the resulting alcohol is oxidized to the aldehyde (3-07) with Dess-Martin periodinane. The aldehyde (3-07) is reacted with the substituted aryl-2-(trimethylsilyloxy)acetonitrile (3-08) after deprotonation with LDA to afford the α-hydroxyketone (3-09). The substituted phenyl-2-(trimethylsilyloxy)acetonitrile (3-08) can be prepared by reacting an appropriate aldehyde with trimethylsilyl cyanide in the presence of catalytic zinc iodide. Acylation of 3-09 with an appropriate acyl chloride or anhydride in the presence of triethylamine provides the ester (3-10). Cyclization of 3-10 is then accomplished with ammonium acetate in acetic acid to afford the oxazole (3-11). The final compounds represented by the structure 3-12 are then obtained by subjecting 3-11 to a palladium-mediated coupling reaction with the appropriate phenyl boronate, and an example set of conditions is given in Scheme 3.
Additional chemistry known to one skilled in the art can be carried out at the R3 position including reductions, Grignard additions, alkylations, fluorinations, acylations, amidations, and heterocycle forming reactions to prepare compounds of the invention. For example, when R3 contains an ester (e.g. CF2COOEt or COOEt) additional functionalization can be carried out by one skilled in the art to make amides as well as primary, secondary and tertiary alcohols. Several examples of these transformations are described in the Examples below.

Specific compounds in the invention contain an oxazole as represented by general structure 4-05. In general, the oxazole compounds of formula 4-05 can be synthesized following the methodology shown in Scheme 4. The aldehyde (3-07) is converted to an aryl-2-(trimethylsilyloxy)acetonitrile (4-01) by treatment with TMSCN in the presence of zinc iodide. Treatment of 4-01 with LDA followed by addition of an appropriately substituted aldehyde affords the α-hydroxyketone (4-02). Acylation of 4-02 with an appropriate acyl chloride or anhydride in the presence of triethylamine provides the ester (4-03). Cyclization is then accomplished with ammonium acetate in acetic acid to afford the oxazole (4-04). Compounds represented by the structure 4-05 are then obtained by subjecting 4-04 to a palladium-mediated coupling reaction with the appropriate aryl boronate, and an example set of conditions is given in Scheme 4.
Additional chemistry known to one skilled in the art can be carried out at the R3 position including reductions, Grignard additions, alkylations, fluorinations, acylations, amidations, and heterocycle forming reactions to prepare compounds of the invention. For example, when R3 contains an ester (e.g. CF2COOEt or COOEt) additional functionalization can be carried out by one skilled in the art to make amides as well as primary, secondary and tertiary alcohols. Several examples of these transformations are described in the Examples below.

In general, triazole compounds of formula 5-08 can be synthesized following the methodology shown in Scheme 5. The substituted pyrazole 5-01 undergoes a SNAr reaction with 4-bromo-1-fluoro-2-nitrobenzene (5-02) in the presence of K2CO3 in DMF to give the nitrophenyl pyrazole (5-03). Then 5-03 can be converted to the aniline (5-04) by hydrogenation in the presence of the platinum (IV) oxide catalyst. The aniline (5-04) is converted to the azide (5-05) using sodium nitrite and sodium azide under acidic conditions. Azide 5-05 reacts with the alkyne (5-06) in the presence of 1,5-cyclooctadiene(pentamethylcyclopentadienyl) ruthenium(II) chloride (Cp*Ru(COD)Cl) to yield the triazole (5-07). Suzuki coupling between the aryl bromide (5-07) and an appropriate aryl boronic acid or boronic ester produces the product (5-08).

Compounds of the invention, can also be prepared by reacting the bromides 8-01 and 8-03 with bis(pinacolato)diboron with appropriate palladium coupling conditions, such as PdCl2(dppf) with a base such as KOAc in DMF to form the boronate intermediates. These boronates could be purified or used directly in palladium coupling with a substituted phenyl or pyridyl bromide to yield 8-02 and 8-03. In Scheme 8 one pyridine isomer is exemplified, but similar chemistry can be used to form other pyridine analogs of the invention.
