2. BACKGROUND OF THE INVENTION

[0003] Obesity, hyperlipidemia, and diabetes have been shown to play a casual role in atherosclerotic cardiovascular diseases, which currently account for a considerable proportion of morbidity in Western society. Further, one human disease, termed “Syndrome X” or “Metabolic Syndrome”, is manifested by defective glucose metabolism (insulin resistance), elevated blood pressure (hypertension), and a blood lipid imbalance (dyslipidemia). See e.g. Reaven, 1993, Annu. Rev. Med. 44:121-131.

[0004] The evidence linking elevated serum cholesterol to coronary heart disease is overwhelming. Circulating cholesterol is carried by plasma lipoproteins, which are particles of complex lipid and protein composition that transport lipids in the blood. Low density lipoprotein (LDL) and high density lipoprotein (HDL) are the major cholesterol-carrier proteins. LDL are believed to be responsible for the delivery of cholesterol from the liver, where it is synthesized or obtained from dietary sources, to extrahepatic tissues in the body. The term “reverse cholesterol transport” describes the transport of cholesterol from extrahepatic tissues to the liver, where it is catabolized and eliminated. It is believed that plasma HDL particles play a major role in the reverse transport process, acting as scavengers of tissue cholesterol. HDL is also responsible for the removal non-cholesterol lipid, oxidized cholesterol and other oxidized products from the bloodstream.

[0005] Atherosclerosis, for example, is a slowly progressive disease characterized by the accumulation of cholesterol within the arterial wall. Compelling evidence supports the belief that lipids deposited in atherosclerotic lesions are derived primarily from plasma apolipoprotein B (apo B)-containing lipoproteins, which include chylomicrons, CLDL, IDL and LDL. The apo B-containing lipoprotein, and in particular LDL, has popularly become known as the “bad” cholesterol. In contrast, HDL serum levels correlate inversely with coronary heart disease. Indeed, high serum levels of HDL is regarded as a negative risk factor. It is hypothesized that high levels of plasma HDL is not only protective against coronary artery disease, but may actually induce regression of atherosclerotic plaque (e.g., see Badimon et al., 1992, Circulation 86:(Suppl. III)86-94; Dansky and Fisher, 1999, Circulation 100:1762-3.). Thus, HDL has popularly become known as the “good” cholesterol.

2.1. Cholesterol Transport

[0006] The fat-transport system can be divided into two pathways: an exogenous one for cholesterol and triglycerides absorbed from the intestine and an endogenous one for cholesterol and triglycerides entering the bloodstream from the liver and other non-hepatic tissue.

[0007] In the exogenous pathway, dietary fats are packaged into lipoprotein particles called chylomicrons, which enter the bloodstream and deliver their triglycerides to adipose tissue for storage and to muscle for oxidation to supply energy. The remnant of the chylomicron, which contains cholesteryl esters, is removed from the circulation by a specific receptor found only on liver cells. This cholesterol then becomes available again for cellular metabolism or for recycling to extrahepatic tissues as plasma lipoproteins.

[0008] In the endogenous pathway, the liver secretes a large, very-low-density lipoprotein particle (VLDL) into the bloodstream. The core of VLDL consists mostly of triglycerides synthesized in the liver, with a smaller amount of cholesteryl esters either synthesized in the liver or recycled from chylomicrons. Two predominant proteins are displayed on the surface of VLDL, apolipoprotein B-100 (apo B-100) and apolipoprotein E (apo E), although other apolipoproteins are present, such as apolipoprotein CIII (apo CIII) and apolipoprotein CII (apo CII). When a VLDL reaches the capillaries of adipose tissue or of muscle, its triglyceride is extracted. This results in the formation of a new kind of particle called intermediate-density lipoprotein (IDL) or VLDL remnant, decreased in size and enriched in cholesteryl esters relative to a VLDL, but retaining its two apoproteins.

[0009] In human beings, about half of the IDL particles are removed from the circulation quickly, generally within two to six hours of their formation. This is because IDL particles bind tightly to liver cells, which extract IDL cholesterol to make new VLDL and bile acids. The IDL not taken up by the liver is catabolized by the hepatic lipase, an enzyme bound to the proteoglycan on liver cells. Apo E dissociates from IDL as it is transformed to LDL. Apo B-100 is the sole protein of LDL.

[0010] Primarily, the liver takes up and degrades circulating cholesterol to bile acids, which are the end products of cholesterol metabolism. The uptake of cholesterol-containing particles is mediated by LDL receptors, which are present in high concentrations on hepatocytes. The LDL receptor binds both apo E and apo B-100 and is responsible for binding and removing both IDL and LDL from the circulation. IN addition, remnant receptors are responsible for clearing chylomicrons and VLDL remnants i.e., IDL). However, the affinity of apo E for the LDL receptor is greater than that of apo B-100. As a result, the LDL particles have a much longer circulating life span than IDL particles; LDL circulates for an average of two and a half days before binding to the LDL receptors in the liver and other tissues. High serum levels of LDL, the “bad” cholesterol, are positively associated with coronary heart disease. For example, in atherosclerosis, cholesterol derived from circulating LDL accumulates in the walls of arteries. This accumulation forms bulky plaques that inhibit the flow of blood until a clot eventually forms, obstructing an artery and causing a heart attack or stroke.

[0011] Ultimately, the amount of intracellular cholesterol liberated from the LDL controls cellular cholesterol metabolism. The accumulation of cellular cholesterol derived from VLDL and LDL controls three processes. First, it reduces the cell's ability to make its own cholesterol by turning off the synthesis of HMGCoA reductase, a key enzyme in the cholesterol biosynthetic pathway. Second, the incoming LDL-derived cholesterol promotes storage of cholesterol by the action of ACAT, the cellular enzyme that converts cholesterol into cholesteryl esters that are deposited in storage droplets. Third, the accumulation of cholesterol within the cell drives a feedback mechanism that inhibits cellular synthesis of new LDL receptors. Cells, therefore, adjust their complement of LDL receptors so that enough cholesterol is brought in to meet their metabolic needs, without overloading (for a review, see Brown & Goldstein, In, The Pharmacological Basis Of Therapeutics, 8th Ed., Goodman & Gilman, Pergaman Press, NY, 1990, Ch. 36, pp. 874-896).

[0012] High levels of apo B-containing lipoproteins can be trapped in the subendothelial space of an artery and undergo oxidation. The oxidized lipoprotein is recognized by scavenger receptors on macrophages. Binding of oxidized lipoprotein to the scavenger receptors can enrich the macrophages with cholesterol and cholesteryl esters independently of the LDL receptor. Macrophages can also produce cholesteryl esters by the action of ACAT. LDL can also be complexed to a high molecular weight glycoprotein called apolipoprotein(a), also known as apo(a), through a disulfide bridge. The LDL-apo(a) complex is known as Lipoprotein(a) or Lp(a). Elevated levels of Lp(a) are detrimental, having been associated with atherosclerosis, coronary heart disease, myocardial infarcation, stroke, cerebral infarction, and restenosis following angioplasty.

2.2. Reverse Cholesterol Transport

[0013] Peripheral (non-hepatic) cells predominantly obtain their cholesterol from a combination of local synthesis and uptake of preformed sterol from VLDL and LDL. Cells expressing scavenger receptors, such as macrophages and smooth muscle cells, can also obtain cholesterol from oxidized apo B-containing lipoproteins.. In contrast, reverse cholesterol transport (RCT) is the pathway by which peripheral cell cholesterol can be returned to the liver for recycling to extrahepatic tissues, hepatic storage, or excretion into the intestine in bile. The RCT pathway represents the only means of eliminating cholesterol from most extrahepatic tissues and is crucial to maintenance of the structure and function of most cells in the body.

[0014] The enzyme in blood involved in the RCT pathway, lecithin:cholesterol acyltransferase (LCAT), converts cell-derived cholesterol to cholesteryl esters, which are sequestered in HDL destined for removal. LCAT is produced mainly in the liver and circulates in plasma associated with the HDL fraction. Cholesterol ester transfer protein (CETP) and another lipid transfer protein, phospholipid transfer protein (PLTP), contribute to further remodeling the circulating HDL population (see for example Bruce et al., 1998, Annu. Rev. Nutr. 18:297-330). PLTP supplies lecithin to HDL, and CETP can move cholesteryl ester made by LCAT to other lipoproteins, particularly apoB-containing lipoproteins, such as VLDL. HDL triglyceride can be catabolized by the extracellular hepatic triglyceride lipase, and lipoprotein cholesterol is removed by the liver via several mechanisms.

[0015] Each HDL particle contains at least one molecule, and usually two to four molecules, of apolipoprotein (apo A-I). Apo A-I is synthesized by the liver and small intestine as preproapolipoprotein which is secreted as a proprotein that is rapidly cleaved to generate a mature polypeptide having 243 amino acid residues. Apo A-I consists mainly of a 22 amino acid repeating segment, spaced with helix-breaking proline residues. Apo A-I forms three types of stable structures with lipids: small, lipid-poor complexes referred to as pre-beta-1 HDL; flattened discoidal particles, referred to as pre-beta-2 HDL, which contain only polar lipids (e.g., phospholipid and cholesterol); and spherical particles containing both polar and nonpolar lipids, referred to as spherical or mature HDL (HDL3 and HDL2). Most HDL in the circulating population contains both apo A-I and apo A-II, a second major HDL protein. This apo A-I- and apo A-II-containing fraction is referred to herein as the AI/AII-HDL fraction of HDL. But the fraction of HDL containing only apo A-I, referred to herein as the AI-HDL fraction, appears to be more effective in RCT. Certain epidemiologic studies support the hypothesis that the AI-HDL fraction is antiartherogenic (Parra et al., 1992, Arterioscler. Thromb. 12:701-707; Decossin et al., 1997, Eur. J. Clin. Invest. 27:299-307).

[0016] Although the mechanism for cholesterol transfer from the cell surface is unknown, it is believed that the lipid-poor complex, pre-beta-1 HDL, is the preferred acceptor for cholesterol transferred from peripheral tissue involved in RCT. Cholesterol newly transferred to pre-beta-1 HDL from the cell surface rapidly appears in the discoidal pre-beta-2 HDL. PLTP may increase the rate of disc formation (Lagrost et al, 1996, J. Biol. Chem. 271:19058-19065), but data indicating a role for PLTP in RCT is lacking. LCAT reacts preferentially with discoidal and spherical HDL, transferring the 2-acyl group of lecithin or phosphatidylethanolamine to the free hydroxyl residue of fatty alcohols, particularly cholesterol, to generate cholesteryl esters (retained in the HDL) and lysolecithin. The LCAT reaction requires an apoliprotein such apo A-I or apo A-IV as an activator. ApoA-I is one of the natural cofactors for LCAT. The conversion of cholesterol to its HDL-sequestered ester prevents re-entry of cholesterol into the cell, resulting in the ultimate removal of cellular cholesterol. Cholesteryl esters in the mature HDL particles of the AI-HDL fraction are removed by the liver and processed into bile more effectively than those derived from the AI/AII-HDL fraction. This may be due, in part, to the more effective binding of AI-HDL to the hepatocyte membrane. Several HDL receptor receptors have been identified, the most well characterized of which is the scavenger receptor class B, type I (SR-BI) (Acton et al., 1996, Science 271:518-520). The SR-BI is expressed most abundantly in steroidogenic tissues (e.g., the adrenals), and in the liver (Landshulz et al., 1996, J. Clin. Invest. 98:984-995; Rigotti et al., 1996, J. Biol. Chem. 271:33545-33549). Other proposed HDL receptors include HB1 and HB2 (Hidaka and Fidge, 1992, Biochem J. 15:161-7; Kurata et al., 1998, J. Atherosclerosis and Thrombosis 4:112-7).

[0017] While there is a consensus that CETP is involved in the metabolism of VLDL- and LDL-derived lipids, its role in RCT remains controversial However, changes in CETP activity or its acceptors, VLDL and LDL, play a role in “remodeling” the HDL population. For example, in the absence of CETP, the HDL becomes enlarged particles that are poorly removed from the circulation (for reviews on RCT and HDLs, see Fielding & Fielding, 1995, J. Lipid Res. 36:211-228; Barrans et al., 1996, Biochem. Biophys. Acta. 1300:73-85; Hirano et al., 1997, Arterioscler. Thromb. Vasc. Biol. 17:1053-1059).

2.2.1. Reverse Transport of Other Lipids

[0018] HDL is not only involved in the reverse transport of cholesterol, but also plays a role in the reverse transport of other lipids, i.e., the transport of lipids from cells, organs, and tissues to the liver for catabolism and excretion. Such lipids include sphingomyelin, oxidized lipids, and lysophophatidylcholine. For example, Robins and Fasulo (1997, J. Clin. Invest. 99:380-384) have shown that HDL stimulates the transport of plant sterol by the liver into bile secretions.

2.3. Peroxisome Proliferator Activated Receptor Pathway

[0019] Peroxisome proliferators are a structurally diverse group of compounds that, when administered to rodents, elicit dramatic increases in the size and number of hepatic and renal peroxisomes, as well as concomitant increases in the capacity of peroxisomes to metabolize fatty acids via increased expression of the enzymes required for the β-oxidation cycle (Lazarow and Fujiki, 1985, Ann. Rev. Cell Biol. 1:489-530; Vamecq and Draye, 1989, Essays Biochem. 24:1115-225; and Nelali et al., 1988, Cancer Res. 48:5316-5324). Chemicals included in this group are the fibrate class of hypolipidermic drugs, herbicides, and phthalate plasticizers (Reddy and Lalwani, 1983, Crit. Rev. Toxicol. 12:1-58). Peroxisome proliferation can also be elicited by dietary or physiological factors, such as a high-fat diet and cold acclimatization.

[0020] Insight into the mechanism whereby peroxisome proliferators exert their pleiotropic effects was provided by the identification of a member of the nuclear hormone receptor superfamily activated by these chemicals (Isseman and Green, 1990, Nature 347:645-650). This receptor, termed peroxisome proliferator activated receptor α (PPARα), was subsequently shown to be activated by a variety of medium and long-chain fatty acids. PPARα activates transcription by binding to DNA sequence elements, termed peroxisome proliferator response elements (PPRE), in the form of a heterodimer with the retinoid X receptor (RXR). RXR is activated by 9-cis retinoic acid (see Kliewer et al., 1992, Nature 358:771-774; Gearing et al., 1993, Proc. Natl. Acad. Sci. USA 90:1440-1444, Keller et al., 1993, Proc Natl. Acad. Sci. USA 90:2160-2164; Heyman et al., 1992, Cell 68:397-406, and Levin et al., 1992, Nature 355:359-361). Since the discovery of PPARα, additional isoforms of PPAR have been identified, e.g., PPARβ, PPARγ and PPARδ, which are have similar functions and are similarly regulated.

[0021] PPREs have been identified in the enhancers of a number of genes encoding proteins that regulate lipid metabolism. These proteins include the three enzymes required for peroxisomal β-oxidation of fatty acids; apolipoprotein A-I; medium-chain acyl-CoA dehydrogenase, a key enzyme in mitochondrial β-oxidation; and aP2, a lipid binding protein expressed exclusively in adipocytes (reviewed in Keller and Whali, 1993, TEM, 4:291-296; see also Staels and Auwerx, 1998, Atherosclerosis 137 Suppl:S19-23). The nature of the PPAR target genes coupled with the activation of PPARs by fatty acids and hypolipidemic drugs suggests a physiological role for the PPARs in lipid homeostasis.

[0022] Pioglitazone, an antidiabetic compound of the thiazolidinedione class, was reported to stimulate expression of a chimeric gene containing the enhancer/promoter of the lipid-binding protein aP2 upstream of the chloroamphenicol acetyl transferase reporter gene (Harris and Kletzien, 1994, Mol. Pharmacol. 45:439-445). Deletion analysis led to the identification of an approximately 30 bp region responsible for pioglitazone responsiveness. In an independent study, this 30 bp fragment was shown to contain a PPRE (Tontonoz et al.,1994, Nucleic Acids Res. 22:5628-5634). Taken together, these studies suggested the possibility that the thiazolidinediones modulate gene expression at the transcriptional level through interactions with a PPAR and reinforce the concept of the interrelatedness of glucose and lipid metabolism.

2.4. Current Cholesterol Management Therapies

[0023] In the past two decades or so, the segregation of cholesterolemic compounds into HDL and LDL regulators and recognition of the desirability of decreasing blood levels of the latter has led to the development of a number of drugs. However, many of these drugs have undesirable side effects and/or are contraindicated in certain patients, particularly when administered in combination with other drugs.

[0024] Bile-acid-binding resins are a class of drugs that interrupt the recycling of bile acids from the intestine to the liver. Examples of bile-acid-binding resins are cholestyramine (QUESTRAN LIGHT, Bristol-Myers Squibb), and colestipol hydrochloride (COLESTID, Pharmacia & Upjohn Company). When taken orally, these positively charged resins bind to negatively charged bile acids in the intestine. Because the resins cannot be absorbed from the intestine, they are excreted, carrying the bile acids with them. The use of such resins, however, at best only lowers serum cholesterol levels by about 20%. Moreover, their use is associated with gastrointestinal side-effects, including constipation and certain vitamin deficiencies. Moreover, since the resins bind to drugs, other oral medications must be taken at least one hour before or four to six hours subsequent to ingestion of the resin, complicating heart patients' drug regimens.

[0025] The statins are inhibitors of cholesterol synthesis. Sometimes, the statins are used in combination therapy with bile-acid-binding resins. Lovastatin (MEVACOR, Merck & Co., Inc.), a natural product derived from a strain of Aspergillus; pravastatin (PRAVACHOL, Bristol-Myers Squibb Co.); and atorvastatin (LIPITOR, Warner Lambert) block cholesterol synthesis by inhibiting HMGCoA, the key enzyme involved in the cholesterol biosynthetic pathway. Lovastatin significantly reduces serum cholesterol and LDL-serum levels. It also slows progression of coronary atherosclerosis. However, serum HDL levels are only slightly increased following lovastatin administration. The mechanism of the LDL-lowering effect may involve both reduction of VLDL concentration and induction of cellular expression of LDL-receptor, leading to reduced production and/or increased catabolism of LDL. Side effects, including liver and kidney dysfunction are associated with the use of these drugs.

[0026] Niacin, also known as nicotinic acid, is a water-soluble vitamin B-complex used as a dietary supplement and antihyperlipidemic agent. Niacin diminishes production of VLDL and is effective at lowering LDL. It is used in combination with bile-acid-binding resins. Niacin can increase HDL when administered at therapeutically effective doses; however, its usefulness is limited by serious side effects.

[0027] Fibrates are a class of lipid-lowering drugs used to treat various forms of hyperlipidemia, elevated serum triglycerides, which may also be associated with hypercholesterolemia. Fibrates appear to reduce the VLDL fraction and modestly increase HDL; however, the effects of these drugs on serum cholesterol is variable. In the United States, fibrates have been approved for use as antilipidemic drugs, but have not received approval as hypercholesterolemia agents. For example, clofibrate (ATROMID-S, Wyeth-Ayerst Laboratories) is an antilipidemic agent that acts to lower serum triglycerides by reducing the VLDL fraction. Although ATROMID-S may reduce serum cholesterol levels in certain patient subpopulations, the biochemical response to the drug is variable, and is not always possible to predict which patients will obtain favorable results. ATROMID-S has not been shown to be effective for prevention of coronary heart disease. The chemically and pharmacologically related drug, gemfibrozil (LOPID, Parke-Davis), is a lipid regulating agent which moderately decreases serum triglycerides and VLDL cholesterol. LOPFD also increases HDL cholesterol, particularly the HDL2 and HDL3 subfractions, as well as both the AI/AII-HDL fraction. However, the lipid response to LOPID is heterogeneous, especially among different patient populations. Moreover, while prevention of coronary heart disease was observed in male patients between the ages of 40 and 55 without history or symptoms of existing coronary heart disease, it is not clear to what extent these findings can be extrapolated to other patient populations (eg., women, older and younger males). Indeed, no efficacy was observed in patients with established coronary heart disease. Serious side-effects are associated with the use of fibrates, including toxicity; malignancy, particularly malignancy of gastrointestinal cancer; gallbladder disease; and an increased incidence in non-coronary mortality. These drugs are not indicated for the treatment of patients with high LDL or low HDL as their only lipid abnormality.

[0028] Oral estrogen replacement therapy may be considered for moderate hypercholesterolemia in post-menopausal women. However, increases in HDL may be accompanied with an increase in triglycerides. Estrogen treatment is, of course, limited to a specific patient population, postmenopausal women, and is associated with serious side effects, including induction of malignant neoplasms; gall bladder disease; thromboembolic disease; hepatic adenoma; elevated blood pressure; glucose intolerance; and hypercalcemia.

[0029] Long chain carboxylic acids, particularly long chain α,ω-dicarboxylic acids with distinctive substitution patterns, and their simple derivatives and salts, have been disclosed for treating atherosclerosis, obesity, and diabetes (See, e.g., Bisgaier et al., 1998, J. Lipid Res. 39:17-30, and references cited therein; International Patent Publication WO 98/30530; U.S. Pat. No. 4,689,344; International Patent Publication WO 99/00116; and U.S. Pat. No. 5,756,344). However, some of these compounds, for example the α,ω-dicarboxylic acids substituted at their α,α′-carbons (U.S. Pat. No. 3,773,946), while having serum triglyceride and serum cholesterol-lowering activities, have no value for treatment of obesity and hypercholesterolemia (U.S. Pat. No. 4,689,344).

[0030] U.S. Pat. No. 4,689,344 discloses β,β,β′,β′-tetrasubstituted-α,ω-alkanedioic acids that are optionally substituted at their α,α,α′,α′ positions, and alleges that they are useful for treating obesity, hyperlipidemia, and diabetes. According to this reference, both triglycerides and cholesterol are lowered significantly by compounds such as 3,3,14,14-tetramethylhexadecane-1,16-dioic acid. U.S. Pat. No. 4,689,344 further discloses that the β,β,β′,β′-tetramethyl-alkanediols of U.S. Pat. No. 3,930,024 also are not useful for treating hypercholesterolemia or obesity.

[0031] Other compounds are disclosed in U.S. Pat. No. 4,711,896. In U.S. Pat. No. 5,756,544, α,ω-dicarboxylic acid-terminated dialkane ethers are disclosed to have activity in lowering certain plasma lipids, including Lp(a), triglycerides, VLDL-cholesterol, and LDL-cholesterol, in animals, and elevating others, such as HDL-cholesterol. The compounds are also stated to increase insulin sensitivity. In U.S. Pat. No. 4,613,593, phosphates of dolichol, a polyprenol isolated from swine liver, are stated to be useful in regenerating liver tissue, and in treating hyperuricuria, hyperlipemia, diabetes, and hepatic diseases in general.

[0032] U.S. Pat. No. 4,287,200 discloses azolidinedione derivatives with anti-diabetic, hypolipidemic, and anti-hypertensive properties. However, these administration of these compounds to patients can produce side effects such as bone marrow depression, and both liver and cardiac cytotoxicity. Further, the compounds disclosed by U.S. Pat. No. 4,287,200 stimulate weight gain in obese patients.

[0033] It is clear that none of the commercially available cholesterol management drugs has a general utility in regulating lipid, lipoprotein, insulin and glucose levels in the blood. Thus, compounds that have one or more of these utilities are clearly needed. Further, there is a clear need to develop safer drugs that are efficacious at lowering serum cholesterol, increasing HDL serum levels, preventing coronary heart disease, and/or treating existing disease such as atherosclerosis, obesity, diabetes, and other diseases that are affected by lipid metabolism and/or lipid levels. There is also is a clear need to develop drugs that may be used with other lipid-altering treatment regimens in a synergistic manner. There is still a further need to provide useful therapeutic agents whose solubility and Hydrophile/Lipophile Balance (HLB) can be readily varied.

5.3. Synthesis of the Compounds of the Invention

[0230] The compounds of the invention can be obtained via the synthetic methodology illustrated in Schemes 1-9. Starting materials useful for preparing the compounds of the invention and intermediates therefor, are commercially available or can be prepared by well known synthetic methods.

[0231] Scheme 1 illustrates the synthesis of mono-protected diols of the formula X, wherein n is an integer ranging from 0 to 5 and R1 and R2 are as defined above. Scheme 1 first outlines the synthesis of mono-protected diols X, wherein n is 0, where esters of formula VII are successively reacted with a first ((R1)p-M) then a second ((R2)p-M) organometallic reagent providing ketones of formula VIII and alcohols of formula IX, respectively. M is a metal group and p is the metal's valency value (e.g., the valency of Li is 1 and that of Zn is 2). Suitable metals include, but are not limited to, Zn, Na, Li, and —Mg-Hal, wherein Hal is a halide selected from iodo, bromo, or chloro. Preferably, M is —Mg-Hal, in which case the organometallic reagents, (R1)p—Mg-Hal and (R2)p—Mg-Hal, are known in the art as a Grignard reagents. Esters of formula VII are available commercially (e.g., Aldrich Chemical Co., Milwaukee, Wis.) or can be prepared by well-known synthetic methods, for example, via esterification of the appropriate 5-halovaleric acid (commercially available, e.g., Aldrich Chemical Co., Milwaukee, Wis.). Both (R1)p-M and (R2)p-M are available commercially (e.g., Aldrich Chemical Co., Milwaukee, Wis.) or can be prepared by well-known methods (see e.g., Kharasch et al., Grignard Reactions of Non-Metallic Substances; Prentice-Hall, Englewood Cliffs, N.J., pp. 138-528 (1954) and Hartley; Patai, The Chemistry of the Metal-Carbon Bond, Vol. 4, Wiley: New York, pp. 159-306 and pp. 162-175 (1989), both citations are incorporated by reference herein). The reaction of a first ((R1)p-M) then a second ((R2)p-M) organometallic reagent with esters VII can be performed using the general procedures referenced in March, J. Advanced Organic Chemistry, Reactions Mechanisms, and Structure, 4th ed., 1992, pp. 920-929 and Eicher, Patai, The Chemistry of the Carbonyl Group, pt. 1, pp. 621-693; Wiley: New York, (1966), incorporated by reference herein. For example, the synthetic procedure described in Comins et al., 1981, Tetrahedron Lett. 22:1085, incorporated by reference herein, can be used. As one example, the reaction can be performed by adding an organic solution of (R1)p-M (about 0.5 to about 1 equivalents) to a stirred, cooled (about 0° C. to about −80° C.) solution comprising esters VII, under an inert atmosphere (e.g., nitrogen) to give a reaction mixture comprising ketones VIII. Preferably, (R1)p-M is added at a rate such that the reaction-mixture temperature remains within about one to two degrees of the initial reaction-mixture temperature. The progress of the reaction can be followed by using an appropriate analytical method, such as thin-layer chromatography or high-performance-liquid chromatography. Next, an organic solution of (R2)p-M (about 0.5 to about 1 equivalent) is added to the reaction mixture comprising ketones VIII in the same manner used to add (R1)p-M. After the reaction providing alcohols IX is substantially complete, the reaction mixture can be quenched and the product can be isolated by workup. Suitable solvents for obtaining alcohols IX include, but are not limited to, dichloromethane, diethyl ether, tetrahydrofuran, benzene, toluene, xylene, hydrocarbon solvents (e.g., pentane, hexane, and heptane), and mixtures thereof. Preferably, the organic solvent is diethyl ether or tetrahydrofuran. Next, alcohols IX are converted to mono-protected diols X, wherein n is 0, using the well-known Williamson ether synthesis. This involves reacting alcohols IX with −O—PG, wherein —PG is a hydroxy-protecting group. For a general discussion of the Williamson ether synthesis, see March, J. Advanced Organic Chemistry; Reactions Mechanisms, and Structure, 4th ed., 1992, pp. 386-387, and for a list of procedures and reagents useful in the Williamson ether synthesis see Larock Comprehensive Organic Transformations; VCH: New York, 1989, pp,. 446-448, both of which references are incorporated herein by reference. As used herein, a “hydroxy-protecting group” means a group that is reversibly attached to a hydroxy moiety that renders the hydroxy moiety unreactive during a subsequent reaction(s) and that can be selectively cleaved to regenerate the hydroxy moiety once its protecting purpose has been served. Examples of hydroxy-protecting groups are found in Greene, T. W., Protective Groups in Organic Synthesis, 3rd edition 17-237 (1999), incorporated herein by reference. Preferably, the hydroxy-protecting group is stable in a basic reaction medium, but can be cleaved by acid. Examples of suitable base-stable acid-labile hydroxy-protecting groups suitable for use with the invention include, but are not limited to, ethers, such as methyl, methoxy methyl, methylthiomethyl, methoxyethoxymethyl, bis(2-chloroethoxy)methyl, tetrahydropyranyl, tetrahydrothiopyranyl, tetrahyrofuranyl, tetrahydrothiofuranyl, 1-ethoxyethyl, 1-methyl-1-methoxyethyl, t-butyl, allyl, benzyl, o-nitrobenzyl, triphenylmethyl, α-naphthyldiphenylmethyl, p-methoxyphenyldiphenylmethyl, 9-(9-phenyl-10-oxo)anthranyl, trimethylsilyl, isopropyldimethylsilyl, t-butyldimethylsilyl, t-butyldiphenylsilyl, tribenzylsilyl, and triisopropylsilyl; and esters, such as pivaloate, adamantoate, and 2,4,6-trimethylbenzoate. Ethers are preferred, particularly straight chain ethers, such as methyl ether, methoxymethyl ether, methylthiomethyl ether, methoxyethoxymethyl ether, bis(2-chloroethoxy)methyl ether. Preferably —PG is methoxymethyl (CH3OCH2—). Reaction of alcohols IX with −O—PG under the conditions of the Williamson ether synthesis involves adding a base to a stirred organic solution comprising HO—PG (e.g., methoxymethanol), maintained at a constant temperature within the range of about 0° C. to about 80° C., preferably at about room temperature. Preferably, the base is added at a rate such that the reaction-mixture temperature remains within about one to two degrees of the initial reaction-mixture temperature. The base can be added as an organic solution or in undiluted form. Preferably, the base will have a base strength sufficient to deprotonate a proton, wherein the proton has a pKa of greater than about 15, preferably greater than about 20. As is well known in the art, the pKa is a measure of the acidity of an acid H-A, according to the equation pKa=−log Ka, wherein Ka is the equilibrium constant for the proton transfer. The acidity of an acid H-A is proportional to the stability of its conjugate base A. For tables listing pKa values for various organic acids and a discussion on pKa measurement, see March, J. Advanced Organic Chemistry; Reactions Mechanisms, and Structure, 4th ed., 1992, pp. 248-272, incorporated herein by reference.

The preferred base is lithium diisopropylamide. Solvents suitable for reacting alcohols IX with —OPG include, but are not limited, to dimethyl sulfoxide, dichloromethane, ethers, and mixtures thereof, preferably tetrahydrofuran. After addition of the base, the reaction mixture can be adjusted to within a temperature range of about 0° C. to about room temperature and alcohols IX can be added, preferably at a rate such that the reaction-mixture temperature remains within about one to two degrees of the initial reaction-mixture temperature. Alcohols of formula IX can be diluted in an organic solvent or added in their undiluted form. The resulting reaction mixture is stirred until the reaction is substantially complete as determined by using an appropriate analytical method, preferably by gas chromatography, then the mono-protected diols X can be isolated by workup and purification.

[0232] Next, Scheme 1 outlines a method useful for synthesizing mono-protected diols X, wherein n is 1. First, compounds of formula XI, wherein X is a suitable leaving group, are reacted with compounds of formula XII, wherein R1 and R2 are as defined above and R8 is H, (C1-C6)alkyl or (C6)aryl, providing compounds of formula XIII. Compounds of formula XI are available commercially (e.g., Aldrich Chemical Co., Milwaukee, Wis.) or can be prepared by well-known methods such as halogenation or sulfonation of butanediol. Compounds of formula XII are also available commercially (e.g., Aldrich Chemical Co., Milwaukee, Wis.) or by well-known methods, such as those listed in Larock Comprehensive Organic Transformations; Wiley-VCH: New York, 1999, pp. 1754-1755 and 1765. A review on alkylation of esters of type XII is given in J. Mulzer in Comprehensive Organic Functional Transformations, Pergamon, Oxford 1995, pp. 148-151 and exemplary synthetic procedures for reacting compounds of formula XI with compounds of formula XII are described in U.S. Pat. No. 5,648,387, column 6 and Ackerly, et al., 1995, J. Med. Chem. 1608, all of which citations are incorporated by reference herein. The reaction requires the presence of a suitable base. Preferably, a suitable base will have a pKa of greater than about 25, more preferably greater than about 30. Suitable bases include, but are not limited to, alkylmetal bases such as methyllithium, n-butyllithium, tert-butyllithium, sec-butyllithium, phenyllithium, phenyl sodium, and phenyl potassium; metal amide bases such as lithium amide, sodium amide, potassium amide, lithium tetramethylpiperidide, lithium diisopropylamide, lithium diethylamide, lithium dicyclohexylamide, sodium hexamethyldisilazide, and lithium hexamethyldisilazide; hydride bases such as sodium hydride and potassium hydride. Metal amide bases, such as lithium diisopropylamide are preferred. Preferably, to react compounds of formula XI with compounds of formula XII, a solution of about 1 to about 2 equivalents of a suitable base is added to a stirred solution comprising esters of formula XII and a suitable organic solvent, under an inert atmosphere, the solution maintained at a constant temperature within the range of about 95° C. to about room temperature, preferably at about −78° C. to about −20° C. Preferably, the base is diluted in a suitable organic solvent before addition. Preferably, the base is added at a rate of about 1.5 moles per hour. Organic solvents suitable for the reaction of compounds of formula XI with the compounds of formula XII include, but are not limited to, dichloromethane, diethyl ether, tetrahydrofuran, dimethylformamide, dimethyl sulfoxide, benzene, toluene, xylene, hydrocarbon solvents (e.g., pentane, hexane, and heptane), and mixtures thereof. After addition of the base, the reaction mixture is allowed to stir for about 1 to about 2 hours, and a compound of formula XI, preferably dissolved in a suitable organic solvent, is added, preferably at a rate such that the reaction-mixture temperature remains within about one to two degrees of the initial reaction-mixture temperature. After addition of compounds of formula XI, the reaction-mixture temperature can be adjusted to within a temperature range of about −20° C. to about room temperature, preferably to about room temperature, and the reaction mixture is allowed to stir until the reaction is substantially complete as determined by using an appropriated analytical method, preferably thin-layer chromatography or high-performance liquid chromatography. Then the reaction mixture is quenched and compounds XIII, wherein n is 1 can be isolated by workup. Compounds XIV are then synthesized by reacting compounds XIII with O—PG according to the protocol described above for reacting alcohols IX with O—PG. Next, compounds XIV can be converted to mono-protected diols X, wherein n is 1, by reduction of the ester group of compounds XIV to an alcohol group with a suitable reducing agent. A wide variety of reagents are available for reduction of such esters to alcohols, e.g., see M. Hudlicky, Reductions in Organic Chemistry, 2nd ed., 1996 pp. 212-217, incorporated by reference herein. Preferably, the reduction is effected with a hydride type reducing agent, for example, lithium aluminum hydride, lithium borohydride, lithium triethyl borohydride, diisobutylaluminum hydride, lithium trimethoxyaluminum hydride, or sodium bis(2-methoxy)aluminum hydride.

Then the reaction mixture can be quenched and mono-protected diols X, wherein n is 1, can be isolated by workup and purification.

Soc. 94:4024), all of which citations are incorporated by reference herein. The preferred oxidizing reagent is pyridinium dichromate. In an alternative synthetic procedure, protected alcohols XVII, wherein K1 is —C(O)OH, can be synthesized by treatment of protected halo-alcohols XV, wherein X is iodo, with CO or CO2, as described in Bailey et al., 1990, J. Org. Chem. 55:5404 and Yanagisawa et al., 1994, J. Am. Chem. Soc. 116:6130, the two of which citations are incorporated by reference herein. Protected alcohols XVII, wherein K1 is —C(O)OR5, wherein R5 is as defined above, can be synthesized by oxidation of mono-protected diols X in the presence of R5OH (see generally, March, J. Advanced Organic Chemistry; Reactions Mechanisms, and Structure, 4th ed., 1992, p. 1196). An exemplary procedures for such an oxidation are described in Stevens et al., 1982, Tetrahedron Lett. 23:4647 (HOCl); Sundararaman et al., 1978, Tetrahedron Lett. 1627 (O3/KOH); Wilson et al., 1982, J. Org. Chem. 47:1360 (t-BuOOH/Et3N); and Williams et al., 1988, Tetrahedron Lett. 29:5087 (Br2), the four of which citations are incorporated by reference herein. Preferably, protected alcohols XVII, wherein K1 is —C(O)OR5 are synthesized from the corresponding carboxylic acid (i.e., XVII, wherein K1 is —C(O)OH) by esterification with R5OH (e.g., see March, J., Advanced Organic Chemistry; Reactions Mechanisms, and Structure, 4th ed., 1992, p. 393-394, incorporated by reference herein). In another alternative synthesis, protected alcohols XVII, wherein K1 is —C(O)OR5, can be prepared from protected halo-alcohols XV by carbonylation with transition metal complexes (see e.g., March, J.

Chem. 3985, the three of which citations are incorporated by reference herein).

[0235] Protected alcohols XVII, wherein K1 is —OC(O)R5, wherein R5 is as defined above, can be prepared by acylation of mono-protected diols X with a carboxylate equivalent such as an acyl halide (i.e., R5C(O)-Hal, wherein Hal is iodo, bromo, or chloro, see e.g., March, J. Advanced Organic Chemistry; Reactions Mechanisms, and Structure, 4th ed., 1992, p. 392 and Org. Synth. Coll. Vol. III, Wiley, NY, pp. 142, 144, 167, and 187 (1955)) or an anhydride (i.e., R5C(O)—O—(O)CR5, see e.g., March, J. Advanced Organic Chemistry; Reactions Mechanisms, and Structure, 4th ed., 1992, p. 392-393 and Org. Synth. Coll.

Preferably, the reaction is conducted by adding a base to a solution comprising mono-protected diols X, a carboxylate equivalent, and an organic solvent, which solution is preferably maintained at a constant temperature within the range of 0° C. to about room temperature. Solvents suitable for reacting mono-protected diols X with a carboxylate equivalent include, but are not limited to, dichloromethane, toluene, and ether, preferably dichloromethane. Suitable bases include, but are not limited to, hydroxide sources, such as sodium hydroxide, potassium hydroxide, sodium carbonate, or potassium carbonate; or an amine such as triethylamine, pyridine, or dimethylaminopyridine, amines are preferred. The progress of the reaction can be followed by using an appropriate analytical technique, such as thin layer chromatography or high performance liquid chromatography and when substantially complete, the product can be isolated by workup and purified if desired.

[0236] Protected alcohols XVII, wherein K1 is one of the following phosphate ester groups

[0237] wherein R6 is defined as above, can be prepared by phosphorylation of mono-protected diols X according to well-known methods (for a general reviews, see Corbridge Phosphorus: An Outline of its Chemistry, Biochemistry, and Uses, Studies in Inorganic Chemistry, 3rd ed., pp. 357-395 (1985); Ramirez et al., 1978, Acc. Chem. Res. 11:239; and Kalckare Biological Phosphorylations, Prentice-Hall, New York (1969); J. B. Sweeny in Comprehensive Organic Functional Group Transformations, A. R. Katritzky, 0. Meth-Cohn and C. W. Rees, Eds. Pergamon: Oxford, 1995, vol 2, pp. 104-109, the four of which are incorporated herein by reference). Protected alcohols XVII wherein K1 is a monophosphate group of the formula:

[0238] wherein R6 is defined as above, can be prepared by treatment of mono-protected diol X with phosphorous oxychloride in a suitable solvent, such as xylene or toluene, at a constant temperature within the range of about 100° C. to about 150° C. for about 2 hours to about 24 hours. After the reaction is deemed substantially complete, by using an appropriate analytical method, the reaction mixture is hydrolyzed with R6—OH. Suitable procedures are referenced in Houben-Weyl, Methoden der Organische Chemie, Georg Thieme Verlag Stuttgart 1964, vol. XII/2, pp. 143-210 and 872-879, incorporated by reference herein. Alternatively, when both R6 are hydrogen, can be synthesized by reacting mono-protected diols X with silyl polyphosphate (Okamoto et al., 1985, Bull Chem. Soc. Jpn. 58:3393, incorporated herein by reference) or by hydrogenolysis of their benzyl or phenyl esters (Chen et al., 1998, J. Org. Chem. 63:6511, incorporated herein by reference). In another alternative procedure, when R6 is (C1-C6)alkyl, (C2-C6)alkenyl, or (C2-C6)alkynyl, the monophosphate esters can be prepared by reacting mono-protected diols X with appropriately substituted phophoramidites followed by oxidation of the intermediate with m-chloroperbenzoic acid (Yu et al., 1988, Tetrahedron Lett. 29:979, incorporated herein by reference) or by reacting mono-protected diols X with dialkyl or diaryl substituted phosphorochloridates (Pop, et al, 1997, Org. Prep. and Proc. Int. 29:341, incorporated herein by reference). The phosphoramidites are commercially available (e.g., Aldrich Chemical Co., Milwaukee, Wis.) or readily prepared according to literature procedures (see e.g., Uhlmann et al. 1986, Tetrahedron Lett. 27:1023 and Tanaka et al., 1988, Tetrahedron Lett. 29:199, both of which are incorporated herein by reference). The phosphorochloridates are also commercially available (e.g., Aldrich Chemical Co., Milwaukee, Wis.) or prepared according to literature methods (e.g., Gajda et al, 1995, Synthesis 25:4099. In still another alternative synthesis, protected alcohols XVII, wherein K1 is a monophosphate group and R6 is alkyl or aryl, can be prepared by reacting IP+(OR6)3 with mono-protected diols X according to the procedure described in Stowell et al., 1995, Tetrahedron Lett. 36:11, 1825 or by alkylation of protected halo alcohols XV with the appropriate dialkyl or diaryl phosphates (see e.g., Okamoto, 1985, Bull Chem. Soc. Jpn. 58:3393, incorporated herein by reference).

XII/2, pp. 881-885. In the same fashion, protected alcohols XVII, wherein K1 is a triphosphate group of the formula:

[0243] can be synthesized by reacting diphosphate protected alcohols XVII, of the formula:

[0244] with the compound of the formula:

[0245] as described above. Alternatively, when R6 is H, protected alcohols XVII wherein K1 is the triphosphate group, can be prepared by reacting mono-protected diols X with salicyl phosphorochloridite and then pyrophosphate and subsequent cleavage of the adduct thus obtained with iodine in pyridine as described in Ludwig et al., 1989, J. Org. Chem. 54:631, incorporated herein by reference.

[0246] Protected alcohols XVII, wherein K1 is —SO3H or a heterocyclic group selected from the group consisting of:

[0247] can be prepared by halide displacement from protected halo-alcohols XV. Thus, when K1 is —SO3H, protected alcohols XVII can by synthesized by reacting protected halo-alcohols XV with sodium sulfite as described in Gilbert Sulfonation and Related Reactions; Wiley: NY, 1965, pp. 136-148 and pp. 161-163; Org. Synth. Coll. Vol. II, Wiley, NY, 558, 564 (1943); and Org. Synth. Coll. Vol. IV, Wiley, NY, 529 (1963), all three of which are incorporated herein by reference. When K1 is one of the above-mentioned heterocycles, protected alcohols XVII can be prepared by reacting protected halo-alcohols XV with the corresponding heterocycle in the presence of a base. The heterocycles are available commercially (e.g., Aldrich Chemical Co., Milwaukee, Wis.) or prepared by well-known synthetic methods (see the procedures described in Ware, 1950, Chem. Rev. 46:403-470, incorporated herein by reference). Preferably, the reaction is conducted by stirring a mixture comprising XV, the heterocycle, and a solvent at a constant temperature within the range of about room temperature to about 100° C., preferably within the range of about 50° C. to about 70° C. for about 10 to about 48 hours. Suitable bases include hydroxide bases such as sodium hydroxide, potassium hydroxide, sodium carbonate, or potassium carbonate. Preferably, the solvent used in forming protected alcohols XVII is selected from dimethylformamide; formamide; dimethyl sulfoxide; alcohols, such as methanol or ethanol; and mixtures thereof. The progress of the reaction can be followed by using an appropriate analytical technique, such as thin layer chromatography or high performance liquid chromatography and when substantially complete, the product can be isolated by workup and purified if desired.

[0248] Protected alcohols XVII, wherein K1 is a heteroaryl ring selected from

[0249] can be prepared by metallating the suitable heteroaryl ring then reacting the resulting metallated heteroaryl ring with protected halo-alcohols XV (for a review, see Katritzky Handbook of Heterocyclic Chemistry, Pergamon Press: Oxford 1985). The heteroaryl rings are available commercially or prepared by well-known synthetic methods (see e.g., Joule et al., Heterocyclic Chemistry, 3rd ed., 1995; De Sarlo et al., 1971, J. Chem. Soc. (C) 86; Oster et al., 1983, J. Org. Chem. 48:4307; Iwai et al., 1966, Chem. Pharm. Bull. 14:1277; and U.S. Pat. No. 3,152,148, all of which citations are incorporated herein by reference). As used herein, the term “metallating” means the forming of a carbon-metal bond, which bond may be substantially ionic in character. Metallation can be accomplished by adding about 2 equivalents of strong organometallic base, preferably with a pKa of about 25 or more, more preferably with a pKa of greater than about 35, to a mixture comprising a suitable organic solvent and the heterocycle. Two equivalents of base are required: one equivalent of the base deprotonates the —OH group or the —NH group, and the second equivalent metallates the heteroaryl ring. Alternatively, the hydroxy group of the heteroaryl ring can be protected with a base-stable, acid-labile protecting group as described in Greene, T. W., Protective Groups in Organic Synthesis, 3rd edition 17-237 (1999), incorporated herein by reference. Where the hydroxy group is protected, only one equivalent of base is required. Examples of suitable base-stable, acid-labile hydroxyl-protecting groups, include but are not limited to, ethers, such as methyl, methoxy methyl, methylthiomethyl, methoxyethoxymethyl, bis(2-chloroethoxy)methyl, tetrahydropyranyl, tetrahydrothiopyranyl, tetrahyrofuranyl, tetrahydrothiofuranyl, 1-ethoxyethyl, 1-methyl-1-methoxyethyl, t-butyl, allyl, benzyl, o-nitrobenzyl, triphenylmethyl, α-naphthyldiphenylmethyl, p-methoxyphenyldiphenylmethyl, 9-(9-phenyl-10-oxo)anthranyl, trimethylsilyl, isopropyldimethylsilyl, t-butyldimethylsilyl, t-butyldiphenylsilyl, tribenzylsilyl, triisopropylsilyl; and esters, such as pivaloate, adamantoate, and 2,4,6-trimethylbenzoate. Ethers are preferred, particularly straight chain ethers, such as methyl ether, methoxymethyl ether, methylthiomethyl ether, methoxyethoxymethyl ether, bis(2-chloroethoxy)methyl ether. Preferably, the pKa of the base is higher than the pKa of the proton of the heterocycle to be deprotonated. For a listing of pKas for various heteroaryl rings, see Fraser et al., 1985, Can. J. Chem. 63:3505, incorporated herein by reference. Suitable bases include, but are not limited to, alkylmetal bases such as methyllithium, n butyllithium, tert-butyl lithium, sec-butyllithium, phenyllithium, phenyl sodium, and phenyl potassium; metal amide bases such as lithium amide, sodium amide, potassium amide, lithium tetramethylpiperidide, lithium diisopropylamide, lithium diethylamide, lithium dicyclohexylamide, sodium hexamethyldisilazide, and lithium hexamethyldisilazide; and hydride bases such as sodium hydride and potassium hydride. If desired, the organometallic base can be activated with a complexing agent, such as N,N,N′,N′-tetramethylethylenediamine or hexamethylphosphoramide (1970, J. Am. Chem. Soc. 92:4664, incorporated by reference herein). Solvents suitable for synthesizing protected alcohols XVII, wherein K1 is a heteroaryl ring include, but are not limited to, diethyl ether; tetrahydrofuran; and hydrocarbons, such as pentane. Generally, metallation occurs alpha to the heteroatom due to the inductive effect of the heteroatom, however, modification of conditions, such as the identity of the base and solvents, order of reagent addition, reagent addition times, and reaction and addition temperatures can be modified by one of skill in the art to achieve the desired metallation position (see e.g., Joule et al., Heterocyclic Chemistry, 3rd ed., 1995, pp. 30-42, incorporated by reference herein) Alternatively, the position of metallation can be controlled by use of a halogenated heteroaryl group, wherein the halogen is located on the position of the heteroaryl ring where metallation is desired (see e.g., Joule et al., Heterocyclic Chemistry, 3rd ed., 1995, p. 33 and Saulnier et al., 1982, J. Org. Chem. 47:757, the two of which citations are incorporated by reference herein). Halogenated heteroaryl groups are available commercially (e.g., Aldrich Chemical Co., Milwaukee, Wis.) or can be prepared by well-known synthetic methods (see e.g., Joule et al., Heterocyclic Chemistry, 3rd ed., 1995, pp. 78, 85, 122, 193, 234, 261, 280, 308, incorporated by reference herein). After metallation, the reaction mixture comprising the metallated heteroaryl ring is adjusted to within a temperature range of about 0° C. to about room temperature and protected halo-alcohols XV (diluted with a solvent or in undiluted form) are added, preferably at a rate such that the reaction-mixture temperature remains within about one to two degrees of the initial reaction-mixture temperature. After addition of protected halo-alcohols XV, the reaction mixture is stirred at a constant temperature within the range of about room temperature and about the solvent's boiling temperature and the reaction's progress can be monitored by the appropriate analytical technique, preferably thin-layer chromatography or high-performance liquid chromatography. After the reaction is substantially complete, protected alcohols XVII can be isolated by workup and purification. It is to be understood that conditions, such as the identity of protected halo-alcohol XV, the base, solvents, orders of reagent addition, times, and temperatures, can be modified by one of skill in the art to optimize the yield and selectivity. Exemplary procedures that can be used in such a transformation are described in Shirley et al., 1995, J. Org. Chem. 20:225; Chadwick et al., 1979, J. Chem. Soc., Perkin Trans. 1 2845; Rewcastle, 1993, Adv. Het. Chem. 56:208; Katritzky et al., 1993, Adv. Het. Chem. 56:155; and Kessar et al., 1997, Chem. Rev. 97:721.

[0250] Protected alcohols XVII, wherein K1 is a lactone selected from:

[0251] can be prepared from compounds of the formula X, XV, or XVI by using well-known condensation reactions and variations of the Michael reaction. Methods for the synthesis of lactones are disclosed in Multzer in Comprehensive Organic Functional Group Transformations, A. R. Katritzky, O. Meth-Cohn and C. W. Rees, Eds. Pergamon: Oxford, 1995, vol 5, pp. 161-173, incorporated herein by reference. When K1 is a beta-lactone of the formula:

Am. Chem. Soc. 98:7874 and Danheiser et al., 1991, J. Org. Chem. 56: 1176, both of which are incorporated herein by reference. This one-pot-addition-lactonization methodology has been reviewed by Multzer in Comprehensive Organic Functional Group Transformations, A. R. Katritzky, O. Meth-Cohn and C. W. Rees, Eds. Pergamon: Oxford, 1995, vol 5, pp. 161, incorporated herein by reference When K1 is a gamma- or delta-lactone of the formula:

[0253] protected alcohols XVII can be prepared from aldehydes XVI according to well known synthetic methodology. For example, the methodology described in Masuyama et al., 2000, J. Org. Chem. 65:494; Eisch et al., 1978, J. Organo. Met. Chem. C8 160; Eaton et al., 1947, J. Org. Chem. 37:1947;Yunker et al., 1978, Tetrahedron Lett. 4651; Bhanot et al., 1977, J. Org. Chem. 42:1623; Ehlinger et al., 1980, J. Am. Chem. Soc. 102:5004; and Raunio et al., 1957, J. Org. Chem. 22:570, all of which citations are incorporated herein by reference. For instance, as described in Masuyama et al., 2000, J. Org. Chem. 65:494, aldehydes XVI can be treated with about 1 equivalent of a strong organometallic base, preferably with a pKa of about 25 or more, more preferably with a pKa of greater than about 35, in a suitable organic solvent to give a reaction mixture.

The reaction mixture is stirred for a period of about 2 hours to about 48 hours, preferably about 5 to about 10 hours, during which time the reaction's progress can be followed by using an appropriate analytical technique, such as thin layer chromatography or high performance liquid chromatography. When the reaction is deemed substantially complete, protected alcohols XVII can be isolated by workup and purified if desired. When K1 is a gamma- or delta-lactone of the formula:

[0255] protected alcohols XVII can be synthesized by deprotonating the respective lactone with a strong base providing the corresponding lactone enolate and reacting the enolate with protected halo-alcohols XV (for a detailed discussion of enolate formation of active methylene compounds such as lactones, see House Modern Synthetic Reactions; W. A. Benjamin, Inc. Philippines 1972 pp. 492-570, and for a discussion of reaction of lactone enolates with electrophiles such as carbonyl compounds, see March, J. Advanced Organic Chemistry; Reactions Mechanisms, and Structure, 4th ed., 1992, pp. 944-945, both of which are incorporated herein by reference). Lactone-enolate formation can be accomplished by adding about 1 equivalent of a strong organometallic base, preferably with a pKa of about 25 or more, more preferably with a pKa of greater than about 35, to a mixture comprising a suitable organic solvent and the lactone. Suitable bases include, but are not limited to, alkylmetal bases such as methyllithium, n-butyllithium, tert-butyllithium, sec-butyllithium, phenyllithium, phenyl sodium, and phenyl potassium; metal amide bases such as lithium amide, sodium amide, potassium amide, lithium tetramethylpiperidide, lithium diisopropylamide, lithium diethylamide, lithium dicyclohexylamide, sodium hexamethyldisilazide, and lithium hexamethyldisilazide; and hydride bases such as sodium hydride and potassium hydride, preferably lithium tetramethylpiperidide. Solvents suitable for lactone-enolate formation include, but are not limited to, diethyl ether and tetrahydrofuran. After enolate formation, the reaction-mixture temperature is adjusted to within the range of about −78° C. to about room temperature, preferably about −50° C. to about 0° C., and protected halo-alcohols XV (diluted with a solvent or in undiluted form) are added, preferably at a rate such that the reaction-mixture temperature remains within about one to two degrees of the initial reaction-mixture temperature. The reaction mixture is stirred for a period of about 15 minutes to about 5 hours, during which time the reaction's progress can be followed by using an appropriate analytical technique, such as thin layer chromatography or high performance liquid chromatography. When the reaction is deemed substantially complete, protected alcohols XVII can be isolated by workup and purified if desired. Protected alcohols XVII, wherein K1 is a lactone of the formula:

[0257] When K1 is a gamma- or delta-lactone of the formula:

The reaction mixture is stirred for a period of about 15 minutes to about 5 hours, during which time the reaction's progress can be followed by using an appropriate analytical technique, such as thin layer chromatography or high performance liquid chromatography. When the reaction is deemed substantially complete, the diester intermediate be isolated by workup and purified if desired. In the second step, the intermediate diester can be reduced, with a hydride reducing agent, to yield a diol of the formula:

[0260] The reduction can be performed according to the procedures referenced in March, J. Advanced Organic Chemistry; Reactions Mechanisms, and Structure, 4th ed., 1992, p. 1214, incorporated herein by reference). Suitable reducing agents include, but are not limited to, lithium aluminum hydride, diisobutylaluminum hydride, sodium borohydride, and lithium borohydride). In the third step, the diol can be oxidatively cyclized with RuH2(PPh3)4 to the product lactones XVII according to the procedure of Yoshikawa et al., 1986, J. Org. Chem. 51:2034 and Yoshikawa et al., 1983, Tetrahedron Lett. 26:2677, both of which citations are incorporated herein by reference. When K1 is a lactone of the formula:

[0261] protected alcohols XVII can be synthesized by reacting the Grignard salts of protected halo-alcohols XV with 5,6-dihydro-2H-pyran-2-one, commercially available (e.g., Aldrich Chemical Co., Milwaukee, Wis.), in the presence of catalytic amounts of a 1-dimethylaminoacetyl)pyrolidine-2yl)methyl-diarylphosphine-copper (I) iodide complex as described in Tomioka et al., 1995, Tetrahedron Lett. 36:4275, incorporated herein by reference. When K1 is

[0262] protected alcohols XVII can be prepared from their corresponding carboxylic acid derivatives (XVII, wherein K1 is —CO2H) as described in Belletire et al, 1988, Synthetic Commun. 18:2063 or from the corresponding acylchlorides (XVII, wherein K1 is —CO-halo) as described in Skinner et al., 1995, J. Am. Chem. Soc. 77:5440, both citations are incorporated herein by reference. The acylhalides can be prepared from the carboxylic acids by well known procedures such as those described in March, J., Advanced Organic Chemistry; Reactions Mechanisms, and Structure, 4th ed., 1992, pp. 437-438, incorporated by reference herein.

Ber. 104:1880 and Campagna et al., 1994, Farmaco, Ed. Sci. 49:653, both of which citations are incorporated herein by reference).

[0265] As further illustrated in Scheme 2, protected alcohols XVII can be deprotected providing alcohols XVIII. The deprotection method depends on the identity of the alcohol-protecting group, see e.g., the procedures listed in Greene, T. W., Protective Groups in Organic Synthesis, 3rd edition 17-237 (1999), particularly see pages 48-49, incorporated herein by reference. One of skill in the art will readily be able to choose the appropriate deprotection procedure. When the alcohol is protected as an ether function (e.g., methoxymethyl ether), the alcohol is preferably deprotected with aqueous or alcoholic acid. Suitable deprotection reagents include, but are not limited to, aqueous hydrochloric acid, p-toluenesulfonic acid in methanol, pyridinium-p-toluenesulfonate in ethanol, Amberlyst H-15 in methanol, boric acid in ethylene-glycol-monoethylether, acetic acid in a is water-tetrahydrofuran mixture, aqueous hydrochloric acid is preferred. Examples of such procedures are described, respectively, in Bernady et al., 1979, J. Org. Chem. 44:1438; Miyashita et al., 1977, J. Org. Chem. 42:3772; Johnston et al., 1988, Synthesis 393; Bongini et al., 1979, Synthesis 618; and Hoyer et al., 1986, Synthesis 655; Gigg et al., 1967, J. Chem. Soc. C, 43 1; and Corey et al., 1978, J.

Alcohols of formula XX can be prepared using the synthetic methods described herein for the synthesis of alcohols XVIII. As further shown in Scheme 3, halides XXI can be synthesized from alcohols XX by halogenation as described above for the synthesis of protected halo-alcohols XV.

[0267] Scheme 4 outlines the synthesis of compounds of formula I by reacting alcohols XVIII with halides XXI via the Williamson ether synthesis, as discussed above for the synthesis of mono-protected diols X. In a preferred procedure, first, a base is added to a stirred organic solution comprising alcohols XVIII, maintained at a constant temperature within the range of about 0° C. to about 80° C., preferably at about room temperature. Preferably, the base is added at a rate such that the reaction-mixture temperature remains within about one to two degrees of the initial reaction-mixture temperature. The base can be added as an organic solution or in undiluted form. Preferably, the base has a pKa of about 15 or greater. Suitable bases include, but are not limited to, alkylmetal bases such as methyllithium, n butyllithium, tert-butyllithium, sec-butyllithium, phenyllithium, phenyl sodium, and phenyl potassium; metal amide bases such as lithium amide, sodium amide, potassium amide, lithium tetramethylpiperidide, lithium diisopropylamide, lithium diethylamide, lithium dicyclohexylamide, sodium hexamethyldisilazide, and lithium hexamethyldisilazide; and hydride bases such as sodium hydride and potassium hydride. The preferred base is lithium diisopropylamide. Suitable solvents include, but are not limited, to dimethyl sulfoxide, dichloromethane, ethers, and mixtures thereof, preferably tetrahydrofuran. After addition of the base, the reaction mixture is adjusted to within a temperature range of about 0° C. to about room temperature and halides XXI are added, preferably at a rate such that the reaction-mixture temperature remains within about one to two degrees of the initial reaction-mixture temperature. Halides XXI can be diluted in an organic solvent or added in undiluted form. The resulting reaction mixture is heated at a constant temperature within the range of about room temperature to about the solvent's boiling temperature until the reaction is substantially complete as determined by using an appropriate analytical method, preferably by gas chromatography. The product I can be isolated by workup and purification.

[0268] As illustrated in Scheme 5, mono-protected diols of the formula XXIV can be prepared from compounds XIII, wherein X, R1, R2, and R1 are as defined above. In the first step, compounds XIII are converted to alcohols of the formula XXII by reduction with a suitable reducing agent. A suitable reducing agent will be selective in that it will reduce the ester function of compounds XIII (i.e., R8O2C—) to hydroxymethylene (i.e., HOCH2—), without displacing leaving group X. The choice of reducing agent will depend on the identities of X and R8. A wide variety of synthetic procedures are available for selective reduction of such esters to alcohols (e.g., see M. Hudlicky, Reductions in Organic Chemistry, 2nd ed., 1996 pp 212-217). For exemplary procedures for reducing esters to alcohols with selective reducing reagents, see Brown et al. 1965, J. Am. Chem. Soc. 87:5614, lithium trimethoxyaluminum hydride; Cerny et al., 1969, Collect. Czech. Chem. Commun. 34:1025, sodium bis(2-methoxy)aluminum hydride; Nystrom et al., 1949, J. Am. Chem. 71:3245, lithium borohydride; and Brown et al., 1980, J. Org. Chem. 45:1, lithium triethyl borohydride. The reaction can be performed by stirring a mixture comprising compounds XIII, a reducing agent, and a suitable organic solvent at a constant temperature within the range of about −20° C. to about 80° C., preferably at about 0° C. to about room temperature. Solvents suitable for reducing compounds XIII include, but are not limited to, methanol, ethanol, isopropanol, dichloromethane, toluene, diethyl ether, tetrahydrofuran or mixtures thereof. The preferred reducing agent is lithium borohydride and the preferred solvent is methanol. The reaction's progress is followed by using an appropriate analytical method, preferably thin-layer chromatography or high-performance liquid chromatography, and, when complete, the reaction mixture can be quenched and the product can be isolated by workup and purification. Next in Scheme 5, the hydroxy moiety of alcohols XXII is protected with a hydroxyl-protecting group providing protected alcohols of the formula XXIII. Preferably, the protecting group is stable to base but labile under acidic conditions. Examples of suitable base-stable, acid-labile alcohol-protecting groups include, but are not limited to, ethers, such as methyl, methoxy methyl, methylthiomethyl, methoxyethoxymethyl, bis(2-chloroethoxy)methyl, tetrahydropyranyl, tetrahydrothiopyranyl, tetrahyrofuranyl, tetrahydrothiofuranyl, 1-ethoxyethyl, 1-methyl-1-methoxyethyl, t-butyl, allyl, benzyl, o-nitrobenzyl, triphenylmethyl, α-naphthyldiphenylmethyl, p-methoxyphenyldiphenylmethyl, 9-(9-phenyl-10-oxo)anthranyl, trimethylsilyl, isopropyldimethylsilyl, t-butyldimethylsilyl, t-butyldiphenylsilyl, tribenzylsilyl, triisopropylsilyl; and esters, such as pivaloate, adamantoate, and 2,4,6-trimethylbenzoate. Ethers are preferred, particularly cyclic ethers, such as tetrahydropyranyl. For example, when -PG is tetrahydropyranyl, protected alcohols XXIII can be prepared by contacting a stirred solution comprising alcohols XXII, an organic solvent, and an acid catalyst with dihydropyran. Preferably, the reaction mixture is stirred for about 1 to about 24 hours, more preferably about 2 to about 10 hours, at a temperature within the temperature range of about 0° C. to about 50° C., preferably at about room temperature. Suitable solvents include, but are not limited to, dichloromethane, hexane, toluene, tetrahydrofuran, acetonitrile, and mixtures thereof. Suitable acids include, but are not limited to, p-toluenesulfonic acid, pyridinium-p-toluene sulfonate, MgBr2-etherate, and alumina. The reaction's progress can be followed by a suitable analytical technique (preferably thin-layer chromatography or high-performance liquid chromatography) and when the reaction is deemed substantially complete, protected alcohols XXIII can be isolated by workup and purification. Exemplary procedures for protecting a hydroxy group as the tetrahydropyranyl ether can be found in Bernady et al., 1979, J. Org. Chem. 44:1438; Miyashita et al., 1977, J. Org. Chem. 42:3772; Johnston et al., 1988, Synthesis 393.; Bongini et al., 1979, Synthesis 618 and Hoyer et al., 1986, Synthesis 655, all of which are incorporated herein by reference. As further shown in Scheme 5, mono-protected diols XXIV can be synthesized by reacting an organic solution of protected alcohols XXIII, with about 1 to about 5 equivalents of a hydroxide source. Preferably, the reaction mixture is maintained within a temperature range of about room temperature to about 110° C., more preferably about 70° C. to about 90° C., preferably for about 1 to about 24 hours, more preferably for about 2 to about 5 hours. The reaction's progress can be followed by using an appropriate analytical technique (such as, thin-layer chromatography or high-performance liquid chromatography) and, when substantially complete, the product can be isolated by workup and purification. For a discussion of hydrolysis of alkylhalides with hydroxide see March, J. Advanced Organic Chemistry; Reactions Mechanisms, and Structure, 4th ed., 1992, p. 370, incorporated herein by reference. Suitable hydroxide sources include, but are not limited to, sodium carbonate, potassium carbonate, calcium carbonate, sodium hydroxide, and potassium hydroxide, preferably sodium carbonate. Suitable solvents include, but are not limited to, dimethyl sulfoxide, dimethyl formamide, hexamethylphosphoramide, and N-methyl-2-pyrrolidone, and mixtures thereof, preferably dimethyl sulfoxide. When the solvent is hexamethylphosphoramide or N-methyl-2-pyrrolidone, water can serve as the hydroxide source (see e.g., Kurz et al., 1985, Isr. J. Chem. 26:339 and Kurz et al., 1986, J. Am. Chem. 108:2960, both of which are incorporated by reference herein).

After the addition, the reaction mixture is stirred at a constant temperature within the range of about room temperature to about 60° C., until the reaction is substantially complete as determined by using an appropriate analytical method, preferably thin-layer chromatography or high-performance-liquid chromatography. Then the reaction mixture can be quenched and compounds of the formula I, wherein K1 and K2 are both —CH2OH, can be isolated by workup and purification.

[0273] In another embodiment, compounds of formula I, wherein K1 and K2 are both —CH2OH, can be oxidized to synthesize compounds of formula XXX wherein R10 is —OH by using an oxidizing agent, for example, an oxidizing agent suitable for oxidizing a primary alcohol to a carboxylic acid (for a discussion see M.

[0335] The invention provides methods of treatment and prophylaxis by administration to a patient of a therapeutically effective amount of a composition comprising a compound of the invention. The patient is an animal, including, but not limited, to an animal such a cow, horse, sheep, pig, chicken, turkey, quail, cat, dog, mouse, rat, rabbit, guinea pig, etc., and is more preferably a mammal, and most preferably a human.

[0336] The present compositions, which comprise one or more compounds of the invention, are preferably administered orally. The compounds of the invention may also be administered by any other convenient route, for example, by infusion or bolus injection, by absorption through epithelial or mucocutaneous linings (e.g., oral mucosa, rectal and intestinal mucosa, etc.) and may be administered together with another biologically active agent. Administration can be systemic or local. Various delivery systems are known, e.g., encapsulation in liposomes, microparticles, microcapsules, capsules, etc., and can be used to administer a compound of the invention. In certain embodiments, more than one compound of the invention is administered to a patient. Methods of administration include but are not limited to intradermal, intramuscular, intraperitoneal, intravenous, subcutaneous, intranasal, epidural, oral, sublingual, intranasal, intracerebral, intravaginal, transdermal, rectally, by inhalation, or topically, particularly to the ears, nose, eyes, or skin. The preferred mode of administration is left to the discretion of the practitioner, and will depend in-part upon the site of the medical condition. In most instances, administration will result in the release of the compounds of the invention into the bloodstream.

[0337] In specific embodiments, it may be desirable to administer one or more compounds of the invention locally to the area in need of treatment. This may be achieved, for example, and not by way of limitation, by local infusion during surgery, topical application, e.g., in conjunction with a wound dressing after surgery, by injection, by means of a catheter, by means of a suppository, or by means of an implant, said implant being of a porous, non-porous, or gelatinous material, including membranes, such as sialastic membranes, or fibers. In one embodiment, administration can be by direct injection at the site (or former site) of an atherosclerotic plaque tissue.

[0338] In certain embodiments, for example, for the treatment of Alzheimer's Disease, it may be desirable to introduce one or more compounds of the invention into the central nervous system by any suitable route, including intraventricular, intrathecal and epidural injection. Intraventricular injection may be facilitated by an intraventricular catheter, for example, attached to a reservoir, such as an Ommaya reservoir.

[0339] Pulmonary administration can also be employed, e.g., by use of an inhaler or nebulizer, and formulation with an aerosolizing agent, or via perfusion in a fluorocarbon or synthetic pulmonary surfactant. In certain embodiments, the compounds of the invention can be formulated as a suppository, with traditional binders and vehicles such as triglycerides.

[0340] In another embodiment, the compounds of the invention can be delivered in a vesicle, in particular a liposome (see Langer, 1990, Science 249:1527-1533; Treat et al., in Liposomes in the Therapy of Infectious Disease and Cancer, Lopez-Berestein and Fidler (eds.), Liss, New York, pp. 353-365 (1989); Lopez-Berestein, ibid., pp. 317-327; see generally ibid.).

[0341] In yet another embodiment, the compounds of the invention can be delivered in a controlled release system. In one embodiment, a pump may be used (see Langer, supra; Sefton, 1987, CRC Crit. Ref. Biomed. Eng. 14:201; Buchwald et al., 1980, Surgery 88:507 Saudek et al., 1989, N. Engl. J Med. 321:574). In another embodiment, polymeric materials can be used (see Medical Applications of Controlled Release, Langer and Wise (eds.), CRC Pres., Boca Raton, Fla. (1974); Controlled Drug Bioavailability, Drug Product Design and Performance, Smolen and Ball (eds.), Wiley, New York (1984); Ranger and Peppas, 1983, J. Macromol. Sci. Rev. Macromol. Chem. 23:61; see also Levy et al., 1985, Science 228:190; During et al., 1989, Ann. Neurol. 25:351; Howard et al., 1989, J. Neurosurg. 71:105). In yet another embodiment, a controlled-release system can be placed in proximity of the target of the compounds of the invention, e.g., the liver, thus requiring only a fraction of the systemic dose (see, e.g., Goodson, in Medical Applications of Controlled Release, supra, vol. 2, pp. 115-138 (1984)). Other controlled-release systems discussed in the review by Langer, 1990, Science 249:1527-1533) may be used.

[0342] The present compositions will contain a therapeutically effective amount of a compound of the invention, optionally more than one compound of the invention, preferably in purified form, together with a suitable amount of a pharmaceutically acceptable vehicle so as to provide the form for proper administration to the patient.

[0343] In a specific embodiment, the term “pharmaceutically acceptable” means approved by a regulatory agency of the Federal or a state government or listed in the U.S. Pharmacopeia or other generally recognized pharmacopeia for use in animals, and more particularly in humans. The term “vehicle” refers to a diluent, adjuvant, excipient, or carrier with which a compound of the invention is administered. Such pharmaceutical vehicles can be liquids, such as water and oils, including those of petroleum, animal, vegetable or synthetic origin, such as peanut oil, soybean oil, mineral oil, sesame oil and the like. The pharmaceutical vehicles can be saline, gum acacia, gelatin, starch paste, talc, keratin, colloidal silica, urea, and the like. In addition, auxiliary, stabilizing, thickening, lubricating and coloring agents may be used. When administered to a patient, the compounds of the invention and pharmaceutically acceptable vehicles are preferably sterile. Water is a preferred vehicle when the compound of the invention is administered intravenously. Saline solutions and aqueous dextrose and glycerol solutions can also be employed as liquid vehicles, particularly for injectable solutions. Suitable pharmaceutical vehicles also include excipients such as starch, glucose, lactose, sucrose, gelatin, malt, rice, flour, chalk, silica gel, sodium stearate, glycerol monostearate, talc, sodium chloride, dried skim milk, glycerol, propylene, glycol, water, ethanol and the like. The present compositions, if desired, can also contain minor amounts of wetting or emulsifying agents, or pH buffering agents.

[0344] The present compositions can take the form of solutions, suspensions, emulsion, tablets, pills, pellets, capsules, capsules containing liquids, powders, sustained-release formulations, suppositories, emulsions, aerosols, sprays, suspensions, or any other form suitable for use. In one embodiment, the pharmaceutically acceptable vehicle is a capsule (see e.g., U.S. Pat. No. 5,698,155). Other examples of suitable pharmaceutical vehicles are described in “Remington's Pharmaceutical Sciences” by E. W. Martin.

[0345] In a preferred embodiment, the compounds of the invention are formulated in accordance with routine procedures as a pharmaceutical composition adapted for intravenous administration to human beings. Typically, compounds of the invention for intravenous administration are solutions in sterile isotonic aqueous buffer. Where necessary, the compositions may also include a solubilizing agent. Compositions for intravenous administration may optionally include a local anesthetic such as lignocaine to ease pain at the site of the injection. Generally, the ingredients are supplied either separately or mixed together in unit dosage form, for example, as a dry lyophilized powder or water free concentrate in a hermetically sealed container such as an ampoule or sachette indicating the quantity of active agent. Where the compound of the invention is to be administered by infusion, it can be dispensed, for example, with an infusion bottle containing sterile pharmaceutical grade water or saline. Where the compound of the invention is administered by injection, an ampoule of sterile water for injection or saline can be provided so that the ingredients may be mixed prior to administration.

[0346] Compositions for oral delivery may be in the form of tablets, lozenges, aqueous or oily suspensions, granules, powders, emulsions, capsules, syrups, or elixirs, for example. Orally administered compositions may contain one or more optionally agents, for example, sweetening agents such as fructose, aspartame or saccharin; flavoring agents such as peppermint, oil of wintergreen, or cherry; coloring agents; and preserving agents, to provide a pharmaceutically palatable preparation. Moreover, where in tablet or pill form, the compositions may be coated to delay disintegration and absorption in the gastrointestinal tract thereby providing a sustained action over an extended period of time. Selectively permeable membranes surrounding an osmotically active driving compound are also suitable for orally administered compounds of the invention. In these later platforms, fluid from the environment surrounding the capsule is imbibed by the driving compound, which swells to displace the agent or agent composition through an aperture. These delivery platforms can provide an essentially zero order delivery profile as opposed to the spiked profiles of immediate release formulations. A time delay material such as glycerol monostearate or glycerol stearate may also be used. Oral compositions can include standard vehicles such as mannitol, lactose, starch, magnesium stearate, sodium saccharine, cellulose, magnesium carbonate, etc. Such vehicles are preferably of pharmaceutical grade.

[0347] The amount of a compound of the invention that will be effective in the treatment of a particular disorder or condition disclosed herein will depend on the nature of the disorder or condition, and can be determined by standard clinical techniques. In addition, in vitro or in vivo assays may optionally be employed to help identify optimal dosage ranges. The precise dose to be employed in the compositions will also depend on the route of administration, and the seriousness of the disease or disorder, and should be decided according to the judgment of the practitioner and each patient's circumstances. However, suitable dosage ranges for oral administration are generally about 0.001 milligram to 200 milligrams of a compound of the invention per kilogram body weight. In specific preferred embodiments of the invention, the oral dose is 0.01 milligram to 70 milligrams per kilogram body weight, more preferably 0.1 milligram to 50 milligrams per kilogram body weight, more preferably 0.5 milligram to 20 milligrams per kilogram body weight, and yet more preferably 1 milligram to 10 milligrams per kilogram body weight. In a most preferred embodiment, the oral dose is 5 milligrams of a compound of the invention per kilogram body weight. The dosage amounts described herein refer to total amounts administered; that is, if more than one compound of the invention is administered, the preferred dosages correspond to the total amount of the compounds of the invention administered. Oral compositions preferably contain 10% to 95% active ingredient by weight.

[0348] Suitable dosage ranges for intravenous (i.v.) administration are 0.01 milligram to 160 milligrams per kilogram body weight, 0.1 milligram to 35 milligrams per kilogram body weight, and 1 milligram to 10 milligrams per kilogram body weight. Suitable dosage ranges for intranasal administration are generally about 0.01 pg/kg body weight to 1 mg/kg body weight. Suppositories generally contain 0.01 milligram to 50 milligrams of a compound of the invention per kilogram body weight and comprise active ingredient in the range of 0.5% to 10% by weight. Recommended dosages for intradermal, intramuscular, intraperitoneal, subcutaneous, epidural, sublingual, intracerebral, intravaginal, transdermal administration or administration by inhalation are in the range of 0.001 milligram to 200 milligrams per kilogram of body weight. Suitable doses of the compounds of the invention for topical administration are in the range of 0.001 milligram to 1 milligram, depending on the area to which the compound is administered. Effective doses may be extrapolated from dose-response curves derived from in vitro or animal model test systems. Such animal models and systems are well known in the art.

[0349] The invention also provides pharmaceutical packs or kits comprising one or more containers filled with one or more compounds of the invention. Optionally associated with such container(s) can be a notice in the form prescribed by a governmental agency regulating the manufacture, use or sale of pharmaceuticals or biological products, which notice reflects approval by the agency of manufacture, use or sale for human administration. In a certain embodiment, the kit contains more than one compound of the invention. In another embodiment, the kit comprises a compound of the invention and another lipid-mediating compound, including but not limited to a statin, a thiazolidinedione, or a fibrate.

[0350] The compounds of the invention are preferably assayed in vitro and in vivo, for the desired therapeutic or prophylactic activity, prior to use in humans. For example, in vitro assays can be used to determine whether administration of a specific compound of the invention or a combination of compounds of the invention is preferred for lowering fatty acid synthesis. The compounds of the invention may also be demonstrated to be effective and safe using animal model systems.

[0351] Other methods will be known to the skilled artisan and are within the scope of the invention.

6. EXAMPLE: SYNTHESIS OF COMPOUND A

6
.1. Method A

[0369] In a three neck 2 liter round bottom flask fitted with a dropping funnel, thermometer, condenser with HCl trap and mechanical stirrer, 146.2 g (2 mol) of tetrahydrofuran (THF) and 102.4 g (0.66 mol) of phosphorus oxychloride were carefully added through the dropping funnel. To the well stirred mixture, 20 ml H2SO4 were added cautiously, and the temperature was brought to 85° C. with an oil bath, then the heating was stopped. After approximately 20 minutes, the temperature rose to 100° C. A strong exothermic reaction then occurred and the temperature rose to 140° C. The color of the reaction mixture turned brown and the evolution of HCl was violent. When the addition was complete (no more gas evolution), the reaction mixture was left to reach 70° C., and 200 ml tap water was added. The mixture was heated at reflux for 30 minutes, and the unreacted THF and the 1,4-dichlorobutane formed as byproduct were removed by azeotropic distillation at atmospheric pressure. The distillation residue was separated in a separatory funnel into an oily layer (the product) and an aqueous layer, which was treated with 200 ml water, then extracted with ether (3×150 ml). The combined organic fractions were washed with sodium bicarbonate 5% (2×150 ml), saturated aqueous ammonium chloride (1×150 ml), dried anhydrous Na2SO4, and the solvent was evaporated in the vacuum. The crude product was distilled under reduced pressure. The main fraction was 83.2 g at 83° to 87° C. (0.4-0.6 mm) at 90% purity. Yield of bis(4-chlorobutyl) ether was 56%.

[0370] 4,4-Dichlorobutyl ether (40 g, 0.2 mol), sodium iodide (67 g, excess) and 500 ml acetone was added to a 3-neck 1-L round bottom flask fitted condenser with a calcium chloride trap and magnetic stirrer. The mixture was heated under reflux for seven days, while the color of the reaction mixture turned yellow. The reaction mixture was then filtered, and the acetone was removed in vacuo. The residue was washed with water (2×100 ml), dried (anhydrous CaCl2), and the crude product was filtered from the drying agent, to give 77 g of bis(4-iodobutyl)ether of ca. 80% purity. Yield ca. 80%.

[0371] THF (150 ml) and ethyl isobutyrate (17.4 g, 22 ml, 0.15 mol) were added under argon to a 1-L 3 neck round bottom flask fitted with a condenser, a dropping funnel, pressure equalizer, and a magnetic stirrer. The mixture was then cooled to −78° C. A solution of LDA (75 ml, 2.0 Mn THF/heptane) was added dropwise with a syringe. After the addition was complete, the reaction mixture was stirred at −78° C. for one additional hour, then the solution of bis-(4-iodobutyl) ether (18 g, 0.05 mmol) and HMPA (10 ml) in 50 ml THF was added dropwise at −78° C.

8. EXAMPLE: EFFECTS OF ILLUSTRATIVE COMPOUNDS OF THE INVENTION ON LDL-CHOLESTEROL, HDL-CHOLESTEROL AND TRIGLYCERIDE LEVELS IN MALE SPRAGUE-DAWLEY RATS

[0392] Illustrative compounds of the invention were administered daily at a dose of 100 mg/kg to chow fed male Sprague-Dawley rats for seven days in the morning by oral gavage in 1.5% carboxymethylcellulose/0.2% Tween-20 (dosing vehicle). Animals were weighed daily. Animals were allowed free access to rodent chow and water throughout the study. After the seventh dose, animals were sacrificed in the evening and blood serum was assayed for lipoprotein cholesterol profiles, serum triglycerides, total cholesterol VLDL, LDL, and HDL cholesterol, and the ratio of HDL cholesterol to that of VLDL plus LDL cholesterol, apolipoproteins A-I, C-II, C-III, and E by immunoelectrophoresis, and percent weight gain.

[0393] Table 1 shows the effect of Compound A, Compound B, Compound C, Compound D and Compound E on serum LDL-cholesterol, HDL-cholesterol and triglycerides in chow-fed male Sprague-Dawley rats following seven days of treatment. The five compounds were tested in two separate experiments. In each experiment, the experimental data were normalized against a control group of rats which received the dosing vehicle alone.

FIG. 1 shows lipoprotein-cholesterol profiles, which indicate that treatment with Compound A results in reduction of LDL cholesterol and elevation of HDL cholesterol when compared to animals treated with the dosing vehicle alone. Compound A treatment also reduces serum triglycerides by 31% and elevates total serum cholesterol by 26% (FIG. 2). The change in total cholesterol was reflected by no change in VLDL cholesterol, a reduction in LDL cholesterol by 41% and an elevation in HDL cholesterol by 49%. The ratio of HDL to non-HDL cholesterol (VLDL plus LDL) improved from 2.6±0.2 to 6.2±1.0 following treatment with Compound A, a 2.44 fold improvement in the ratio (FIG. 2). Compared to control treatment, Compound A-treatment of the rats elevated apolipoprotein A-I and E by 16% and 46%, respectively, and reduced apolipoprotein C-II and C-III by 20% and 16%, respectively (FIG. 3). Compound A also reduced the percentage body weight gain resulting from growth compared to the control group after seven days of treatment (63.4±1.9% vs. 68.3±1.2% weight gain; FIG. 4). Accordingly, Compounds A, B, C, D, and E or pharmaceutically acceptable salts thereof are useful for promoting higher levels of circulating HDL, the “good” cholesterol, and raising the ratio of HDL:non-HDL cholesterol in the blood.

9. EXAMPLE: EFFECTS OF ILLUSTRATIVE COMPOUNDS OF THE INVENTION ON LDL-CHOLESTEROL, HDL-CHOLESTEROL AND TRIGLYCERIDE LEVELS IN OBESE FEMALE ZUCKER RATS

9.1. Experiment A

[0395] Dosing vehicle, Compound A (86 mg/kg of body weight) or troglitazone (120 mg/kg of body weight) was administered to eight week old female obese Zucker rats daily for seven days in the morning by oral gavage in 1.5% carboxymethylcellulose/0.2% Tween-20. Troglitazone was obtained commercially. Finely crushed tablets were suspended in vehicle for dosing. Orbital blood samples were obtained following a six-hour fast prior to the initial dose and also following the seventh dose.

[0396] Blood serum was assayed for total cholesterol and triglycerides (FIG. 5), lipoprotein cholesterol profiles (FIG. 6), VLDL plus LDL cholesterol combined (also referred to as apo B containing lipoprotein cholesterol or non-HDL cholesterol), HDL cholesterol, and the ratio of HDL cholesterol to that of VLDL plus LDL cholesterol (FIG. 7), serum glucose, and non-esterified fatty acids (FIG. 8), and percent weight gain (FIG. 9). In the Zucker rats, Compound A increased total serum cholesterol by 3.3-fold after one week of treatment, while the vehicle and troglitazone treatment resulted in a reduction of this variable (FIG. 5A). Serum triglycerides were markedly reduced with Compound A treatment 68% (FIG. 5B). Lipoprotein cholesterol profiles show treatment with Compound A resulted in a marked alteration in the distribution of cholesterol among lipoproteins (FIG. 6). In particular, Compound A caused a marked elevation in HDL cholesterol after one week of treatment. Using the serum total cholesterol values (FIG. 5A) and the lipoprotein cholesterol distribution (FIG. 6), the amount of cholesterol associated with non-HDL (i.e., VLDL plus LDL) and HDL were determined (FIG. 7). Compound A increased non-HDL cholesterol slightly (+10.3%) but significantly increased HDL cholesterol 3.9-fold. In contrast, troglitazone reduced non-HDL and HDL cholesterol by 67% and 4%, respectively. When these data are expressed as a ratio of HDL/non-HDL cholesterol it can be clearly seen that Compound A markedly improves the ratio from 4.2 (pre-treatment) to 14.9 (one week treatment), a 3.6-fold increase.

[0397] Typically, impaired glucose tolerance is the metabolic symptom of eight to 12 week-old-obese female Zucker rats. The animals are able to maintain normal to slightly elevated glucose levels at the expense of elevated insulin levels. As shown in FIG. 8A, pre-treatment and post-treatment serum glucose levels were similar for all treatments within normal range. Compound A treatment did not induce a hypoglycemic state. Typically, these animals also have elevated non-esterified fatty acids in this pre-diabetic state. These levels were reduced with Compound A and troglitazone treatment by 52% and 65%, respectively (FIG. 8B).

[0398] One adverse effect of troglitazone treatment is weight gain, largely due to increased adipose mass. As shown in FIG. 9, troglitazone treatment in female Zucker rats caused the greatest increase in weight gain (+11.6%). Zucker rats treated with vehicle alone showed a 6.6% increased weight after seven days, while Zucker rats treated with Compound A showed a 5.4% increase in body weight.

[0399] Accordingly, Compound A, or a pharmaceutically acceptable salt thereof, is useful for reducing serum triglycerides, elevating circulating HDL, improving the ratio of HDL:LDL in the blood, without the adverse side effect of promoting weight gain in a patient to whom the compound is administered.

9.2. Experiments B, C, D, & E

[0400] In a number of different experiments, illustrative compounds of the invention and troglitazone were administered daily at various doses to 10-week old chow fed obese female Zucker rats for 14 days in the morning by oral gavage in 1.5% carboxymethylcellulose/0.2% Tween-20 (dosing vehicle). Animals were weighed daily. Animals were allowed free access to rodent chow and water throughout the study. Blood glucose was determined after a 6-hour fast in the afternoon without anesthesia from a tail vein. Serum was also prepared from a blood sample subsequently obtained from the orbital venous plexus (with O2/CO2 anesthesia) prior to and after one week treatment and used lipid and insulin determinations. At two weeks, blood glucose was again determined after a 6-hour fast without anesthesia from a tail vein. Soon thereafter, animals were sacrificed by CO2 inhalation in the evening and cardiac blood serum was collected and assessed for various lipids and insulin. Body weight was determined daily prior to dosing and at the time of euthanasia. Table 2 shows effects of the Compound A and Compound B compared to troglitazone on the percent change in serum non-HDL cholesterol, HDL-cholesterol, triglyceride and body weight (relative to pretreatment values) in fasted (6 hours) chow-fed obese female Zucker rats.

[0401] Generally, Compound A improved the ratio of non-HDL cholesterol to HDL cholesterol content relative to both control animals and troglitazone-treated animals. Additionally, Compound A generally reduced serum triglyceride content and did not cause the body weight increases seen in troglitazone-treated animals.

[0402] The data from Experiment C concerning Compound A are graphically depicted in FIGS. 10-16. Compound A treatment reduced serum triglyceride levels at all doses. Reduction in serum triglycerides was dose dependent with a minimal effective dose of approximately 3 mg/kg (FIG. 10). Reduction of triglycerides by troglitazone was observed only at doses of 40 and 120 mg/kg (FIG. 10).

[0403] Compound A treatment elevated serum total cholesterol in a dose- and treatment duration-dependent manner beginning at a dose of approximately 10 mg/kg/day (FIG. 11). With longer treatment (i.e. two weeks verses one week) the elevation of serum total cholesterol was greater for all Compound A doses greater or equal to 10 mg/kg (FIG. 11). For troglitazone, total cholesterol was only modestly elevated at the highest dose (120 mg/kg) and only after two weeks of treatment (FIG. 11). Elevation in serum cholesterol observed with Compound A were largely reflected by a marked elevation in HDL-cholesterol. The rise in HDL-cholesterol caused by Compound A was dose- and treatment duration-dependent. At the highest Compound A dose used (i.e. 100 mg/kg), HDL-cholesterol was elevated 9-fold (802% increase) after two weeks of treatment (FIG. 11). Troglitazone caused a markedly lower elevation in HDL at the 120 mg/kg dose (122% increase).

[0404] Blood glucose (FIG. 12) and serum insulin levels (FIG. 13) were determined from fasted rats just prior to and following one and two weeks of treatment. Blood glucose was maintained at slightly elevated levels for 10-12 week old obese Zucker rats during treatment with all doses of Compound A and troglitazone, with the exception of the 100 mg/kg and 40 mg/kg doses, respectively, whereby both compounds showed a tendency to lower blood glucose. For troglitazone, this glucose lowering effect was not dose dependent, since it did not occur at 120 mg/kg. Relative to pretreatment values, serum insulin (FIG. 13) in control animals sharply rose as the animals became older. At dosages of 1 and 3 mg/kg of Compound A, a similar sharp rise in insulin levels was observed. However, at the higher Compound A doses, this sharp rise in serum insulin was largely curtailed or minimized. For troglitazone, serum insulin levels were reduced following two weeks of treatment at all doses tested (FIG. 13). One measure of improved insulin sensitivity (i.e. as impaired glucose tolerance progresses as the animals age), is a sustained or improved ratio of fasting serum glucose to insulin. The glucose to insulin ratio in these animals is shown in FIG. 14. In the control and the 1 and 3 mg/kg of Compound A groups, the glucose to insulin ratio declined by approximately ⅓ to ½ as the animals aged two weeks. In contrast, at 10 and 30 mg/kg Compound A, the glucose to insulin ratio was sustained at pretreatment levels. At 100 mg/kg of Compound A, the glucose to insulin ratio was reduced, suggesting this dose superseded the optimal dose for sustaining insulin sensitivity for the compound. Troglitazone at all doses sustained the glucose to insulin ratio after one week treatment and increased this ratio after two weeks of treatment (FIG. 14).

[0405]
FIG. 15 shows the weekly percent weight gain in the Zucker rats during treatment Control rats gained 9.1 and 16 percent of their initial weight after one and two weeks respectively. With Compound A treatment, all treatment groups gained weight. At the lower doses (1 and 3 mg/kg) weight gain was similar to controls. However, weight gain was markedly reduced at 10, 30 and 100 mg/kg of Compound A after both one and two weeks of treatment, suggesting Compound A may have thermogenic properties. In contrast, troglitazone treatment caused increased weight gain after one week at 120 mg/kg and increased weight gain after two weeks at all treatment doses (12, 40 and 120 mg/kg).

[0406] Percent liver to body weight was determined after two weeks of treatment at the time of sacrifice (FIG. 16). Following Compound A treatment, liver to body weight increased in a dose dependent manner. For troglitazone, liver to body weight was reduced at all doses. The gain in liver to body weight in rats suggests to the inventors, without intending any limitation as to the mechanism by which the compounds of the invention act, that Compound A may be a peroxisomal proliferator activator receptor ligand.

[0407] Accordingly, Compound A, or a pharmaceutically acceptable salt thereof, is useful for improving the ratio HDL:non-HDL cholesterol in the blood, reducing serum triglycerides, elevating HDL-cholesterol, lowering blood glucose, and/or improving insulin sensitivity, without the adverse side effect of promoting weight gain in a patient to whom the compound is administered

10. EXAMPLE: EFFECT OF COMPOUND A ON LIPOPROTEIN CHOLESTEROL PROFILE IN LDL RECEPTOR-DEFICIENT MICE

[0408] Homozygous familial hypercholesterolemia is a rare human disease (˜1/1,000,000) characterized by absent or defective LDL receptors, markedly elevated serum LDL cholesterol levels and very early and severe onset of atherosclerosis. The more common form of this disease in humans, heterozygous familial hypercholesterolemia, occurs in about one in every 500 humans. Patients with the heterozygous form of this disease also present with elevated LDL levels and early onset of atherosclerosis.

[0409] The effect of Compound A on LDL levels in a murine model of homozygous familial hypercholesterolemia (Ishibashi et al., 1993, J. Clin. Invest. 92:883-893; Ishibashi et al., 1994,J. Clin. Invest. 93:1885-1893) was studied. LDL receptor-deficient mice have elevated LDL cholesterol relative to wild type mice when fed a chow diet. When fed cholesterol-enriched diets, these mice develop atherosclerosis.

[0410]
FIG. 17 shows the lipoprotein cholesterol profiles (Bisgaier et al., J. Lipid Res. 38:2502-2515) of 4 chow-fed female LDL receptor deficient mice prior to and following therapy with 300 mg/kg/day of Compound A. All mice showed a rapid and significant reduction in LDL cholesterol after one week of treatment. In addition, FIG. 17 shows that Compound A caused HDL elevation in all treated mice.

[0411] Accordingly, Compound A, or a pharmaceutically acceptable salt thereof, is useful for reducing circulating LDL levels and/or increasing circulating HDL in a patient with a dyslipidemia, including homozygous familial hypercholesterolemia.

11. EXAMPLE: EFFECT OF ILLUSTRATIVE COMPOUNDS OF THE INVENTION ON THE SYNTHESIS OF NON-SAPONIFIED AND SAPONIFIED LIPIDS IN HEPATOCYTES ISOLATED FROM A MALE SPRAGUE-DAWLEY RAT

[0412] A male Sprague-Dawley rat was anesthetized by administration of sodium pentobarbitol by intraparitoneal injection at 50 mg/kg. In situ perfusion of the liver was performed as follows. The abdomen of the animal was opened, the portal vein canulated, and the liver perfused with WOSH solution (149 mM NaCl, 9.2 mM Na HEPES, 1.7 mM Fructose, 0.5 mM EGTA, 0.029 mM Phenol red, 10 U/ml heparin, pH 7.5) at a flow rate of 30 ml/min for 6 minutes. To digest the liver, DSC solution (6.7 mM KCl, 143 mM NaCl, 9.2 mM Na HEPES, 5 mM CaCl2-2H2O, 1.7 mM Fructose, 0.029 mM Phenol red, 0.2% BSA, 100 U/ml collagenase Type I, 93 U/ml Hyaluronidase, 160 BAEE/ml trypsin inhibitor, pH 7.5) was perfused through the liver at a flow rate of 30 ml/min for 6 minutes at a temperature of 37° C. After digestion, cells were dispersed in a solution of DMEM-(DMEM containing 2 mM GlutMax-1, 0.2% BSA, 5% FBS, 12 nM insulin, 1.2 μM hydrocortisone) to stop the digestion process. The crude cell suspension was filtered through three layers of stainless steel mesh with pore sizes of 250, 106, and 75 μm respectively. Filtered cells were centrifuged at 50×g for two minutes and the supernatant discarded. The resulting cell pellet was resuspended in DMEM and centrifuged again. This final cell pellet was resuspended in DMEM+HS solution (DMEM containing 2 mM GlutMax-1, 20 nM delta-aminolevulinic acid, 17.4 mM MEM non-essential amino acids, 20% FBS, 12 nM insulin, 1.2 μM hydrocortisone) and plated to form monolayer cultures at a density of 100×103 cells/cm2 on collagen coated culture dishes. Four hours after initial plating, media was changed to DMEM+ (DMEM containing 2 mM GlutMax-1, 20 nM delta-aminolevulinic acid, 17.4 mM MEM non-essential amino acids, 10% FBS, 12 nM insulin, 1.2 μM hydrocortisone) and remained on cells overnight.

[0413] To test the effect of illustrative compounds of the invention on synthesis rates of non-saponified and saponified lipids, the monolayer cultures were exposed to 1 μM of lovastatin or 100 μM Compound A, B, D, E or F in DMEM+ containing 1 μCi/ml 14C-acetate. Control cells were exposed to the same media lacking lovastatin or the test compounds. All cells were exposed to 0.1% DMSO. Metabolic labeling with 14C-acetate continued for 2 hr at 37° C. After labeling, cells were washed twice with 1 ml of PBS followed by lysing in 1 ml of deionized water. Cells were scraped from the dishes, transferred to glass tubes and sonicated. 2.5 ml of 2:1 chloroform/methanol mixture was added followed by 1.5 ml of Phosphate Buffered Saline (PBS). To correct for extraction efficiency in the upcoming extractions, 3000 dpm of 3H-cholesterol was added to each tube. Tubes were shaken for 30 min. to extract lipids into the organic phase followed by centrifugation for 10 minutes at 1000×g to separate the organic and aqueous phases. The lower organic phase containing total lipids was removed and placed in a new tube. The organic solution was evaporated under N2. The dry lipid extract was resuspended in 1 ml of 93% ethanol containing 1 M KOH and placed at 70° C. for 2.5 hours. After the reaction and cooling, 2 ml of hexane and 2.5 ml of water was added to each tube followed by rigorous shaking for 10 min. Tubes were centrifuged for 10 min. at 1000×g and the organic (top) layer containing the non-saponified lipids was transferred to a new tube followed by evaporation of the organic solvent under N2. The aqueous phase containing the saponified lipids was also transferred to a new tube. The non-saponified lipid extract, after drying, was resuspended in toluene and an aliquot of the suspension was added to a scintillation cocktail for radioactive counting. The number of 14C counts representing the incorporation of 14C-acetate into non-saponified lipids was corrected for extraction efficiency, based on the recovery of 3H counts extracted. To isolate saponified lipids, 1.5 ml of aqueous phase solution was mixed with 400 μl of 1 M HCl, and then lipids were extracted by the addition of 2.5 ml of 2:1 chloroform:methanol, 1.5 ml of PBS, and 1 ml of water followed by rigorous shaking and isolation of the organic phase. The organic phase from this extraction was evaporated under N2 and resuspended in toluene. Its radioactivity was counted using scintillant to provide the rate of 14C-acetate incorporation into saponified lipid.

[0414]
FIG. 18 shows the rates of saponified and non-saponified lipid synthesis following treatment with lovastatin and illustrative compounds of the invention. Data are represented as a percent of no compound treatment (control). Data are represented as the mean of three measurements +/− one standard deviation. The data indicate that illustrative compounds of the invention are useful for inhibiting saponified and/or non-saponified lipid synthesis. In particular, Compound A reduced the rate of both saponified and non-saponified lipid synthesis by at least 85% in the rat hepatocytes. Compounds E and F also reduced the rates of saponified fatty acid synthesis. Accordingly, Compound A, or a pharmaceutically acceptable salt thereof, is useful for inhibiting the synthesis of saponified and/or non-saponified fatty acids. Compounds E and E, or pharmaceutically acceptable salts thereof, are also useful for inhibiting the synthesis of saponified fatty acids.

12. EXAMPLE: MEASUREMENT OF THE CYTOTOXICITY OF ILLUSTRATIVE COMPOUNDS OF THE INVENTION

[0415] To evaluate the effects of illustrative compounds of the invention on cytotoxicity, monolayer hepatocyte cultures were exposed to increasing concentrations of up to 250μM Compound A, B, C, or D in DMEM+ for 24 hours. Control cells were exposed to the same media lacking a test compound. All cells were exposed to 0.1% DMSO. The measure of cytotoxicity, release of lactate dehydrogenase (LDH) from the cytosolic compartment of hepatocyte monolayer cultures, reflects damage to the plasma membrane. The assay, based on the method of Wroblewski and LaDue,1955, Proc. Soc. Exp. Biol. Med. 90:210-213; see also Ulrich et al., 1995, Toxicol. Lett. 82/83:107-115, describing the use of hepatocytes as models for hepatic toxicity), measures the LDH activity in tissue culture medium and a cell homogenate. Briefly, all the media were removed from plates and transferred to a separate plate. Following removal of media, attached cells were lysed with a hypotonic Tris/Glycerol/EDTA buffer (0.1 M Tris, 20% glycerol, 1 mM EDTA pH 7.3). Activity of LDH in medium and cells was measured spectrophotometrically by monitoring the rate of pyruvate reduction to lactate, coupled with oxidation of NADH; the rate of absorbance change was measured at 340 nm. Cytotoxicity was expressed as ratio using the following equation: (LDH in medium/(LDH in medium+LDH in solubilized hepatocytes))=R.

[0416]
FIG. 19 shows the results of these experiments. At all concentrations tested, none of Compounds A, B, C, or D resulted in the secretion of more than approximately 25-30% of total LDH in the medium. For Compound A, toxicity was assayed at 2.5-fold the compound's therapeutically effective concentration. These experiments indicate that the toxicity of the compounds of the invention is low. Accordingly, Compounds A, B, C and D, and pharmaceutically acceptable thereof, are potentially suitable for human use without toxic side effects.

13. EXAMPLE: INSULIN SENSITIZATION EFFECTS OF COMPOUND A

[0417] The effects of Compound A on rate of differentiation of 3T3-L1 cells from a “committed pre-adipocyte” to an “adipocyte” phenotype in the absence or presence of insulin is tested. The differentiation of 3T3-L1 cells to an adipocyte-like phenotype is highly dependent upon insulin. This insulin-dependent changes in cellular morphology and metabolism, including: expression of adipocyte-specific genes, greatly increased levels of glucose uptake and metabolism, induction of GLUT4 (and increased expression of GLUT1) glucose transporters, greatly increased lipid synthesis and deposition of intracellular lipid droplets. In this assay the degree of differentiation was a reflection of the rate of lipid synthesis, as measured through incorporation of 14C-acetate over 2 hours. Thus the ability of a compound to stimulate a submaximal insulin response would suggest an insulin-sensitizing activity (Kletzein et al., 1991, Molecular Pharm.41:393-398).

[0418] 3T3-L1 stem cells were induced to differentiate with dexamethasone, isobutylmethylxanthine and insulin (Green and Kehinde, 1975, Cell 5:19-27). Cells were plated in Dulbecco's modified Eagle medium containing 10% calf serum and grown to confluence. Cells were then refreshed with 10% fetal calfserum, and treated with 0.5 mM isobutylmethylxanthine and 250 nM dexamethasone, but no additional insulin, for 48 hours. This treatment induced the differentiation of 3T3-L1 cells into pre-adipocytes. Conversion of preadipocytes to adipocyte phenotype requires the removal of dexamethasone and the presence of insulin, which stimulates differentiation of preadipocytes into adipocytes in a concentration- and time-dependent manner. A maximal insulin effect occurs at about 100 nM insulin, and leads to nearly complete (95-100%) conversion to adipocytes within 4 days.

[0419] The preadipocytes were then treated for 4 days with various concentrations of Compound A in 5% fetal calf serum in Dulbecco's modified Eagles medium, with or without a submaximal concentration of insulin (30 nM). Following this four-day treatment, the predipocytes were pulsed with 0.1 μCi 14C-acetate per well for 2 hours. Cell were then washed with phosphate buffered saline, lysed with 0.1 N NaOH, and 14C-acetate incorporation into lipids was determined using phase separation and liquid scintillation counting.

[0420]
FIG. 20 shows the results of these experiments. Data are represented as the mean +/− one standard deviation for three measurements. Without Compound A, 14C-acetate incorporation into lipids was 4201 DPM in the presence of insulin and 545 DPM in the absence of insulin. In the presence of Compound A, 14C-acetate incorporation increased by approximately 40%, indicating that Compound A potentiates the insulin-dependent increase in acetate incorporation. Accordingly, Compound A or a pharmaceutically acceptable salt thereof is suitable for use as an insulin sensitizer.
