BACKGROUND OF THE INVENTIONPeroxisome Proliferator-Activated Receptors (PPARs) are implicated in a number of biological processes and disease states including Type 2 diabetes, hyperinsulinemia, hyperlipidemia, hyperuricemia, hypercholesteremia, atherosclerosis, one or more risk factors for cardiovascular disease, Syndrome X, hypertriglyceridemia, hyperglycemia, obesity, eating disorders and suppressing appetite.
Diabetes, Hyperinsulinemia, Hypertriglyceridemia, Hyperglycemia, Atherosclerosis and Cardiovascular DiseaseDiabetes mellitus, commonly called diabetes, refers to a disease process derived from multiple causative factors and characterized by elevated levels of plasma glucose, referred to as hyperglycemia. See, e.g., LeRoith, D. et al., (eds.), D
There are two major forms of diabetes: Type 1 diabetes (formerly referred to as insulin-dependent diabetes or IDDM); and Type 2 diabetes (formerly referred to as non-insulin dependent diabetes or NIDDM).
Type 1 diabetes is the result of an absolute deficiency of insulin, the hormone which regulates glucose utilization. This insulin deficiency is usually characterized by β-cell destruction within the Islets of Langerhans in the pancreas, which usually leads to absolute insulin deficiency. Type 1 diabetes has two forms: Immune-Mediated Diabetes Mellitus, which results from a cellular mediated autoimmune destruction of the β-cells of the pancreas; and Idiopathic Diabetes Mellitus, which refers to forms of the disease that have no known etiologies.
Type 2 diabetes is a complex disease characterized by defects in glucose and lipid metabolism. Typically there are perturbations in many metabolic parameters including increases in fasting plasma glucose levels, free fatty acid levels and triglyceride levels (hypertriglyceridemia), as well as a decrease in the ratio of HDL/LDL. One of the principal underlying causes of diabetes is thought to be when muscle, fat and liver cells fail to respond to normal concentrations of insulin (insulin resistance). Insulin resistance may be due to reduced numbers of insulin receptors on these cells or a dysfunction of signaling pathways within the cells or both. Insulin resistance is characteristically accompanied by a relative, rather than absolute, insulin deficiency. Type 2 diabetes can range from predominant insulin resistance with relative insulin deficiency to predominant insulin deficiency with some insulin resistance.
The beta cells in insulin resistant individuals initially compensate for this insulin resistance by secreting abnormally high amounts of insulin (hyperinsulinemia). Over time, these cells become unable to produce enough insulin to maintain normal glucose levels, indicating progression to Type 2 diabetes. When inadequate amounts of insulin are present to compensate for insulin resistance and adequately control glucose, a state of impaired glucose tolerance develops. In a significant number of individuals, insulin secretion declines further and the plasma glucose level rises, resulting in the clinical state of diabetes. Type 2 diabetes can be due to a profound resistance to insulin stimulating regulatory effects on glucose and lipid metabolism in the main insulin-sensitive tissues: muscle, liver and adipose tissue. This resistance to insulin responsiveness results in insufficient insulin activation of glucose uptake, oxidation and storage in muscle and inadequate insulin repression of lipolysis in adipose tissue and of glucose production and secretion in liver. In Type 2 diabetes, free fatty acid levels are often elevated in obese and some non-obese patients and lipid oxidation is increased. Consequently, in Type 2 diabetics, adipose tissue mass is often increased.
Type 2 diabetes is brought on by a combination of genetic and acquired risk factors—including a high-fat diet, lack of exercise and aging. Worldwide, Type 2 diabetes has become an epidemic, driven by increases in obesity and a sedentary lifestyle, widespread adoption of western dietary habits and the general aging of the population in many countries. In 1985, an estimated 30 million people worldwide had diabetes—by 2000, this figure had increased 5-fold, to an estimated 154 million people. The number of people with diabetes is expected to double between now and 2025, to about 300 million.
Therapies aimed at reducing peripheral insulin resistance are available. The most relevant to this invention are drugs of the thiazolidinedione (TZD) class namely troglitazone, pioglitazone and rosiglitazone. In the US these have been marketed under the names Rezulin™, Avandia™ and Actos™, respectively. The principal effect of these drugs is to improve glucose homeostasis. Notably in diabetics treated with TZDs there are increases in peripheral glucose disposal rates indicative of increased insulin sensitivity in both muscle and fat. Treatment of diabetes also improves Islet (of Langerhans) function, specifically, insulin secretion, islet architecture, beta cell mass and the like.
Premature development of atherosclerosis and increased rate of cardiovascular and peripheral vascular diseases are characteristic features of patients with diabetes, with hyperlipidemia being an important precipitating factor for these diseases.
HyperlipidemiaHyperlipidemia is a condition generally characterized by an abnormal increase in serum lipids in the bloodstream and, as noted above, is an important risk factor in developing atherosclerosis and coronary heart disease. For a review of disorders of lipid metabolism, see, e.g., Wilson, J. et al., (ed.), Disorders of Lipid Metabolism, Chapter 23, Textbook of Endocrinology, 9th Edition, (W.B. Sanders Company, Philadelphia, Pa. U.S.A. 1998; this reference and all references cited therein are herein incorporated by reference). Serum lipoproteins are the carriers for lipids in the circulation. They are classified according to their density: chylomicrons; very low-density lipoproteins (VLDL); intermediate density lipoproteins (IDL); low density lipoproteins (LDL); and high density lipoproteins (HDL). Hyperlipidemia is usually classified as primary or secondary hyperlipidemia. Primary hyperlipidemia is generally caused by genetic defects, while secondary hyperlipidemia is generally caused by other factors, such as various disease states, drugs and dietary factors. Alternatively, hyperlipidemia can result from both a combination of primary and secondary causes of hyperlipidemia.
HypercholesterolemiaHypercholesterolemia, a form of hyperlipidemia, is characterized by excessive high levels of blood cholesterol. The blood cholesterol pool is generally dependant on dietary uptake of cholesterol from the intestine and biosynthesis of cholesterol throughout the body, especially the liver. The majority of the cholesterol in plasma is carried on apolipoprotein B-containing lipoproteins, such as the very-low-density lipoproteins (VLDL), low-density lipoproteins (LDL), intermediate density lipoproteins (IDL) and high density lipoproteins (HDL). Hypercholesterolemia is characterized by elevated LDL cholesterol levels. The risk of coronary artery disease in man increases when LDL and VLDL levels increase. Conversely, high HDL levels are protective against coronary artery disease (see Gordon, D. and Rifkind, B. N. Engl. J. Med. 1989 321: 1311-15; and Stein, O and Stein, Y. Atherosclerosis 1999 144: 285-303). Therefore, although it is desirable to lower elevated levels of LDL, it is also desirable to increase HDL levels.
Initial treatment for hypercholesterolemia is to place the patients on a low fat/low cholesterol diet coupled with adequate physical exercise, followed by drug therapy when LDL-lowering goals are not met by diet and exercise alone. HMG-CoA reductase inhibitors (statins) are useful for treating conditions associated with high LDL levels. Other important anti-lipidemia drugs include fibrates such as gemfibril and clofibrate, bile acid sequestrant such as cholestyramine and colestipol, probucol and nicotinic acid analogs.
Elevated cholesterol levels are in turn associated with a number of disease states, including coronary artery disease, angina pectoris, carotid artery disease, strokes, cerebral arteriosclerosis and xanthoma.
DyslipidemiaDyslipidemia or abnormal levels of lipoproteins in blood plasma, is a frequent occurrence among diabetics and has been shown to be one of the main contributors to the increased incidence of coronary events and deaths among diabetic subjects (see, e.g., Joslin, E. Ann. Chim. Med. (1927) 5: 1061-1079). Epidemiological studies since then have confirmed the association and have shown a several-fold increase in coronary deaths among diabetic subjects when compared with nondiabetic subjects (see, e.g., Garcia, M. J. et al., Diabetes (1974) 23: 105-11; and Laakso, M. and Lehto, S. Diabetes Reviews (1997) 5(4): 294-315). Several lipoprotein abnormalities have been described among diabetic subjects (Howard B., et al., Atherosclerosis (1978) 30: 153-162).
ObesityObesity has reached epidemic proportions globally with more than 1 billion adults overweight—at least 300 million of them clinical obese—and is a major contributor to the global burden of chronic diseases including cardiovascular disease problems, conditions associated with insulin resistance such as Type 2 diabetes and certain types of cancers. The likelihood of developing Type 2 diabetes and hypertension rises steeply with increasing body fatness. Weight reduction leads to correction of a number of obesity-associated endocrine and metabolic disorders.
Effective weight management for individuals and groups at risk of developing obesity involves a range of long term strategies. These include prevention, weight maintenance, management of co-morbidities and weight loss. Existing treatment strategies include caloric restriction programs, surgery (gastric stapling) and drug intervention. The currently available anti-obesity drugs can be divided into two classes: central acting and peripheral acting. Three marketed drugs are Xenical (Orlistat), Merida (Sibutramine) and Adipex-P (Phentermine). Xenical is a non-ic acting GI lipase inhibitor which is indicated for short and long term obesity management. Merida reduces food intake by re-uptake inhibition of primarily norepinephrine and serotonin. Adipex-P is a phenteramine with sympathomimetic activities and suppresses appetite. It is indicated only for short term use. A more drastic solution to permanent weight loss is surgery and a gastric by-pass which limits absorption of calories through massive reduction in stomach size.
Carrying extra body weight and body fat go hand and hand with the development of diabetes. People who are overweight (BMI greater than 25) are at a much greater risk of developing type 2 diabetes than normal weight individuals. Almost 90% of people with type 2 diabetes are overweight.
Syndrome X, Hyperuricemia, Eating Disorders and Suppressing AppetiteSyndrome X (including metabolic syndrome) is loosely defined as a collection of abnormalities including hyperinsulinemia, hyperuricemia, obesity, elevated levels of triglycerides, fibrinogen, small dense LDL particles and plasminogen activator inhibitor 1 (PAI-1) and decreased levels of HDL-c. These abnormalities are associated with eating disorders, particularly an overactive appetite.
PPARPPARs are members of the nuclear receptor superfamily of transcription factors, a large and diverse group of proteins that mediate ligand-dependent transcriptional activation and repression. They play a role in controlling expression of proteins that regulate lipid metabolism. Furthermore, the PPARs are activated by fatty acids and fatty acid metabolites. Three PPAR subtypes have been isolated: PPARα, PPARβ (also referred to as δ or NUC1) and PPARγ. Each receptor shows a different pattern of gene expression by binding to DNA sequence elements, termed PPAR response elements (PPRE). In addition, each receptor show a difference in activation by structurally diverse compounds. To date, PPREs have been identified in the enhancers of a number of genes encoding proteins that regulate lipid metabolism suggesting that PPARs play a pivotal role in the adipogenic signaling cascade and lipid homeostasis (Keller, H. and Wahli, W. Trends Endoodn. Met. (1993) 4:291-296. PPARα is found in the liver, heart, kidney, muscle, brown adipose tissue and gut and is involved in stimulating β-oxidation of fatty acids. PPARα is also involved in the control of cholesterol levels in rodents and in humans. Fibrates are weak PPARα agonists that are effective in the treatment of lipid disorders. In humans, they have been shown to lower plasma triglycerides and LDL cholesterol. In addition, PPARα agonists have also been reported to prevent diabetes and to improve insulin sensitivity and reduce adiposity in obese and diabetic rodents (see Koh, E. H. et al. Diabetes (2003) 52:2331-2337; and Guerre-Millo, M. et al. J. Biol. Chem. (2000) 275: 16638-16642).
PPARβ is ubiquitously expressed. Activation of PPARβ increases HDL levels in rodents and monkeys (see Oliver, W. R. et al. PNAS (2001) 98:5306-5311; and Leibowitz, M. D. et al. FEBS Letters (2000) 473:333-336). Moreover, PPARβ has been recently shown to be a key regulator of lipid catabolism and energy uncoupling in skeletal muscle cells (Dressel, U. et al. Mol. Endocrinol. (2003) 17: 2477-2493). In rodents, activation of PPARβ induces fatty β-oxidation in skeletal muscle and adipose tissue, leading to protection against diet-induced obesity and diabetes (see Wang, Y. X. et al. Cell (2003) 113:159-170; and Tanaka et al. PNAS (2003) 100:15924-15929). In human macrophages, PPARβ activation also increases the reverse cholesterol transporter ATP-binding cassette A1 and induces apolipoprotein A1-specific cholesterol efflux (see Oliver, W. R. et al. PNAS (2001) 98:5306-5311). Activation also increases energy expenditure.
PPAR-γ is expressed most abundantly in adipose tissue and is thought to regulate adipocyte differentiation. Drugs of the thiazolidinedione (TZD) class namely troglitazone, pioglitazone and rosiglitazone are potent and selective activators of PPAR-γ. In human, they increase insulin action, reduce serum glucose and have small but significant effects on reducing serum triglyceride levels in patients with type 2 diabetes.
Certain compounds that activate or otherwise interact with one or more of the PPARs have been implicated in the regulation of triglyceride and cholesterol levels in animal models. (See e.g., U.S. Pat. No. 5,859,501 and PCT publications WO 97/28149 and 99/04815.
Taken together, these data clearly indicate that PPARs agonists are useful in treating hypertriglyceridemia, hypercholesterolemia, obesity and type 2 diabetes.
Anti-lipidemia, anti-obesity and anti-diabetes agents are still considered to have non-uniform effectiveness, in part because of poor patient compliance due to unacceptable side effects. For Anti-lipidemia and anti-obesity agents, these side effects include diarrhea and gastrointestinal discomfort. For anti-diabetic agents, they include weight gain, edema and hepatotoxicity. Furthermore, each type of drug does not work equally well in all patients.

The term “carboxylic acid equivalent” also refers to those moieties that may be converted into a carboxylic acid moiety in vivo. Such groups are generally known to one of skill in the art. While it is recognized that these groups initially may be non-acidic, suitable in vivo equivalents include aldehydes (CHO) and alcohols CH2OH and esters CH2OR wherein R can be alkyl, alkenyl, cycloalkyl, haloalkyl, heteroalkyl, araalkyl, aryl, heteroaryl, heterocyclyl, arylalkyl, arylalkenyl, alkoxy, haloalkoxy, aryloxy, alkylamino, haloalkylamino, dialkylamino, dihaloalkylamino, arylamino, diarylamino, araalkylamino, diaraalkylamino or other groups that are cleaved under physiological conditions to provide a hydroxyl group that can be oxidized in vivo to provide a carboxylic acid.
Compounds that have the same molecular formula but differ in the nature or sequence of bonding of their atoms or the arrangement of their atoms in space are termed “isomers”. Isomers that differ in the arrangement of their atoms in space are termed “stereoisomers”. Stereoisomers that are not mirror images of one another are termed “diastereomers” and those that are non-superimposable mirror images of each other are termed “enantiomers”. When a compound has an asymmetric center, for example, it is bonded to four different groups, a pair of enantiomers is possible. An enantiomer can be characterized by the absolute configuration of its asymmetric center and is described by the R- and S-sequencing rules of Cahn and Prelog or by the manner in which the molecule rotates the plane of polarized light and designated as dextrorotatory or levorotatory (i.e., as (+) or (−)-isomers respectively). A chiral compound can exist as either individual enantiomer or as a mixture thereof. A mixture containing equal proportions of the enantiomers is called a “racemic mixture”.
The compounds of this invention may exist in stereoisomeric form if they possess one or more asymmetric centers or a double bond with asymmetric substitution and, therefore, can be produced as individual stereoisomers or as mixtures. Unless otherwise indicated, the description is intended to include individual stereoisomers as well as mixtures. The methods for the determination of stereochemistry and the separation of stereoisomers are well-known in the art (see discussion in Chapter 4 of A

“Prodrugs” means any compound which releases an active parent drug according to Formula (I) in vivo when such prodrug is administered to a mammalian subject. Prodrugs of a compound of Formula (I) are prepared by modifying functional groups present in the compound of Formula (I) in such a way that the modifications may be cleaved in vivo to release the parent compound. Prodrugs include compounds of Formula (I) wherein a hydroxy, amino or sulfhydryl group in a compound of Formula (I) is bonded to any group that may be cleaved in vivo to regenerate the free hydroxyl, amino or sulfhydryl group, respectively. Examples of prodrugs include, but are not limited to esters (e.g., acetate, formate and benzoate derivatives), amides/imides, carbamates (e.g., N,N-dimethylaminocarbonyl) of hydroxy functional groups in compounds of Formula (I) and the like.

With reference to the methods of the present invention, the following terms are used with the noted meanings:
The terms “treating” or “treatment” of a disease includes:
(1) preventing the disease, i.e., causing the clinical symptoms of the disease not to develop in a mammal that may be exposed to or predisposed to the disease but does not yet experience or display symptoms of the disease,
(2) inhibiting the disease, i.e., arresting or reducing the development of the disease or its clinical symptoms or
(3) relieving the disease, i.e., causing regression of the disease or its clinical symptoms.
The term “therapeutically effective amount” means the amount of the subject compound that will elicit the biological or medical response of a tissue, animal or human that is being sought by the researcher, veterinarian, medical doctor or other clinician. “A therapeutically effective amount” includes the amount of a compound that, when administered to a mammal for treating a disease, is sufficient to effect such treatment for the disease. The “therapeutically effective amount” will vary depending on the compound, the disease and its severity and the age, weight, etc., of the mammal to be treated.
The term “patient” means all mammals, including humans. Examples of patients include, but are not limited to, humans, cows, dogs, cats, goats, sheep, pigs and rabbits.
The term “mammal” includes, without limitation, humans, domestic animals (e.g., dogs or cats), farm animals (cows, horses or pigs), monkeys, rabbits, mice and laboratory animals.
The term “insulin resistance” can be defined generally as a disorder of glucose metabolism. More specifically, insulin resistance can be defined as the diminished ability of insulin to exert its biological action across a broad range of concentrations producing less than the expected biologic effect. (see, e.g., Reaven, G. M. J. Basic & Clin. Phys. & Pharm. (1998) 9: 387-406 and Flier, J. Ann Rev. Med. (1983) 34: 145-60). Insulin resistant persons have a diminished ability to properly metabolize glucose and respond poorly, if at all, to insulin therapy. Manifestations of insulin resistance include insufficient insulin activation of glucose uptake, oxidation and storage in muscle and inadequate insulin repression of lipolysis in adipose tissue and skeletal muscle and of glucose production and secretion in liver. Insulin resistance can cause or contribute to polycystic ovarian syndrome, Impaired Glucose Tolerance (IGT), gestational diabetes, hypertension, obesity, atherosclerosis and a variety of other disorders. Eventually, the insulin resistant individuals can progress to a point where a diabetic state is reached. The association of insulin resistance with glucose intolerance, an increase in plasma triglyceride and a decrease in high-density lipoprotein cholesterol concentrations, high blood pressure, hyperuricemia, smaller denser low-density lipoprotein particles and higher circulating levels of plasminogen activator inhibitor-1), has been referred to as “Syndrome X” (see, e.g., Reaven, G. M. Physiol. Rev. (1995) 75: 473-486).
The term “diabetes mellitus” or “diabetes” means a disease or condition that is generally characterized by metabolic defects in production and utilization of glucose which result in the failure to maintain appropriate blood sugar levels in the body. The result of these defects is elevated blood glucose, referred to as “hyperglycemia.” Two major forms of diabetes are Type 1 diabetes and Type 2 diabetes. As described above, Type 1 diabetes is generally the result of an absolute deficiency of insulin, the hormone which regulates glucose utilization. Type 2 diabetes often occurs in the face of normal or even elevated levels of insulin and can result from the inability of tissues to respond appropriately to insulin. Most Type 2 diabetic patients are insulin resistant and have a relative deficiency of insulin, in that insulin secretion can not compensate for the resistance of peripheral tissues to respond to insulin. In addition, many Type 2 diabetics are obese. Other types of disorders of glucose homeostasis include Impaired Glucose Tolerance, which is a metabolic stage intermediate between normal glucose homeostasis and diabetes and Gestational Diabetes Mellitus, which is glucose intolerance in pregnancy in women with no previous history of Type 1 or Type 2 diabetes.
The term “secondary diabetes” is diabetes resulting from other identifiable etiologies which include: genetic defects of β cell function (e.g., maturity onset-type diabetes of youth, referred to as “MODY,” which is an early-onset form of Type 2 diabetes with autosomal inheritance; see, e.g., Fajans, S. et al. Diabet. Med. (1996) (9 Suppl 6): S90-5 and Bell, G. et al., Annu. Rev. Physiol. (1996) 58: 171-86; genetic defects in insulin action; diseases of the exocrine pancreas (e.g., hemochromatosis, pancreatitis and cystic fibrosis); certain endocrine diseases in which excess hormones interfere with insulin action (e.g., growth hormone in acromegaly and cortisol in Cushing's syndrome); certain drugs that suppress insulin secretion (e.g., phenyloin) or inhibit insulin action (e.g., estrogens and glucocorticoids); and diabetes caused by infection (e.g., rubella, Coxsackie and CMV); as well as other genetic syndromes.
The guidelines for diagnosis for Type 2 diabetes, impaired glucose tolerance and gestational diabetes have been outlined by the American Diabetes Association (see, e.g., The Expert Committee on the Diagnosis and Classification of Diabetes Mellitus, Diabetes Care, (1999) Vol 2 (Suppl 1): S5-19).
The term “hyperinsulinemia” refers to the presence of an abnormally elevated level of insulin in the blood. Similarly, the term “hyperuricemia” refers to the presence of an abnormally elevated level of uric acid in the blood. The term “hyperlipidemia” refers to the presence of an abnormally elevated level of lipids in the blood. Hyperlipidemia can appear in at least three forms: (1) hypercholesterolemia, i.e., an elevated cholesterol level; (2) hypertriglyceridemia, i.e., an elevated triglyceride level; and (3) combined hyperlipidemia, i.e., a combination of hypercholesterolemia and hypertriglyceridemia.
The term “secretagogue” means a substance or compound that stimulates secretion. For example, an insulin secretagogue is a substance or compound that stimulates secretion of insulin.
The term “hemoglobin” or “Hb” refers to a respiratory pigment present in erythrocytes, which is largely responsible for oxygen transport. A hemoglobin molecule comprises four polypeptide subunits (two α chain s and two β chain s, respectively). Each subunit is formed by association of one globin protein and one heme molecule which is an iron-protoporphyrin complex. The major class of hemoglobin found in normal adult hemolysate is adult hemoglobin (referred to as “HbA”; also referred to HbA0 for distinguishing it from glycated hemoglobin, which is referred to as “HbA1,” described infra) having α2β2 subunits. Trace components such as HbA2 (α2δ2) can also be found in normal adult hemolysate.
Among classes of adult hemoglobin HbAs, there is a glycated hemoglobin (referred to as “HbA1,” or “glycosylated hemoglobin”), which may be further fractionated into HbA1a1, HbA1a2, HbA1b and HbA1c with an ion exchange resin fractionation. All of these subclasses have the same primary structure, which is stabilized by formation of an aldimine (Schiff base) by the amino group of N-terminal valine in the β subunit chain of normal hemoglobin HbA and glucose (or, glucose-6-phosphate or fructose) followed by formation of ketoamine by Amadori rearrangement.
The term “glycosylated hemoglobin” (also referred to as “HbA1c,”, “GHb”, “hemoglobin-glycosylated”, “diabetic control index” and “glycohemoglobin”; hereinafter referred to as “hemoglobin A1c”) refers to a stable product of the nonenzymatic glycosylation of the β-chain of hemoglobin by plasma glucose. Hemoglobin A1c comprises the main portion of glycated hemoglobins in the blood. The ratio of glycosylated hemoglobin is proportional to blood glucose level. Therefore, hemoglobin A1c rate of formation directly increases with increasing plasma glucose levels. Since glycosylation occurs at a constant rate during the 120-day lifespan of an erythrocyte, measurement of glycosylated hemoglobin levels reflect the average blood glucose level for an individual during the preceding two to three months. Therefore determination of the amount of glycosylated hemoglobin HbA1c can be a good index for carbohydrate metabolism control. Accordingly, blood glucose levels of the last two months can be estimated on the basis of the ratio of HbA1c to total hemoglobin Hb. The analysis of the hemoglobin A1c in blood is used as a measurement enabling long-term control of blood glucose level (see, e.g., Jain, S. et al., Diabetes (1989) 38: 1539-1543; Peters A. et al., JAMA (1996) 276: 1246-1252).
The term “symptom” of diabetes, includes, but is not limited to, polyuria, polydipsia and polyphagia, as used herein, incorporating their common usage. For example, “polyuria” means the passage of a large volume of urine during a given period; “polydipsia” means chronic, excessive thirst; and “polyphagia” means excessive eating. Other symptoms of diabetes include, e.g., increased susceptibility to certain infections (especially fungal and staphylococcal infections), nausea and ketoacidosis (enhanced production of ketone bodies in the blood).
The term “complication” of diabetes includes, but is not limited to, microvascular complications and macrovascular complications. Microvascular complications are those complications which generally result in small blood vessel damage. These complications include, e.g., retinopathy (the impairment or loss of vision due to blood vessel damage in the eyes); neuropathy (nerve damage and foot problems due to blood vessel damage to the nervous); and nephropathy (kidney disease due to blood vessel damage in the kidneys). Macrovascular complications are those complications which generally result from large blood vessel damage. These complications include, e.g., cardiovascular disease and peripheral vascular disease. Cardiovascular disease refers to diseases of blood vessels of the heart. See. e.g., Kaplan, R. M. et al., “Cardiovascular diseases” in H
The term “atherosclerosis” encompasses vascular diseases and conditions that are recognized and understood by physicians practicing in the relevant fields of medicine. Atherosclerotic cardiovascular disease, coronary heart disease (also known as coronary artery disease or ischemic heart disease), cerebrovascular disease and peripheral vessel disease are all clinical manifestations of atherosclerosis and are therefore encompassed by the terms “atherosclerosis” and “atherosclerotic disease”.
The term “antihyperlipidemic” refers to the lowering of excessive lipid concentrations in blood to desired levels. Similarly, the term “antiuricemic” refers to the lowering of excessive uric acid concentrations in blood to desired levels.
The term “modulate” refers to the treating, prevention, suppression, enhancement or induction of a function or condition. For example, the compounds of the present invention can modulate hyperlipidemia by lowering cholesterol in a human, thereby suppressing hyperlipidemia.
The term “triglyceride(s)” (“TGs”), as used herein, incorporates its common usage. TGs consist of three fatty acid molecules esterified to a glycerol molecule and serve to store fatty acids which are used by muscle cells for energy production/expenditure or are taken up and stored in adipose tissue.
Because cholesterol and TGs are water insoluble, they must be packaged in special molecular complexes known as “lipoproteins” in order to be transported in the plasma. Lipoproteins can accumulate in the plasma due to overproduction and/or deficient removal. There are at least five distinct lipoproteins differing in size, composition, density and function. In the cells of the small of the intestine, dietary lipids are packaged into large lipoprotein complexes called “chylomicrons”, which have a high TG and low-cholesterol content. In the liver, TG and cholesterol esters are packaged and released into plasma as TG-rich lipoprotein called very low density lipoprotein (“VLDL”), whose primary function is the endogenous transport of TGs made in the liver or released by adipose tissue. Through enzymatic action, VLDL can be either reduced and taken up by the liver or transformed into intermediate density lipoprotein (“IDL”). IDL, is in turn, either taken up by the liver or is further modified to form the low density lipoprotein (“LDL”). LDL is either taken up and broken down by the liver or is taken up by extrahepatic tissue. High density lipoprotein (“HDL”) helps remove cholesterol from peripheral tissues in a process called reverse cholesterol transport.
The term “dyslipidemia” refers to abnormal levels of lipoproteins in blood plasma including both depressed and/or elevated levels of lipoproteins (e.g., elevated levels of LDL, VLDL and depressed levels of HDL).
Exemplary Primary Hyperlipidemia include, but are not limited to, the following:
(1) Familial Hyperchylomicronemia, a rare genetic disorder which causes a deficiency in an enzyme, LP lipase, that breaks down fat molecules. The LP lipase deficiency can cause the accumulation of large quantities of fat or lipoproteins in the blood;
(2) Familial Hypercholesterolemia, a relatively common genetic disorder caused where the underlying defect is a series of mutations in the LDL receptor gene that result in malfunctioning LDL receptors and/or absence of the LDL receptors. This brings about ineffective clearance of LDL by the LDL receptors resulting in elevated LDL and total cholesterol levels in the plasma;
(3) Familial Combined Hyperlipidemia, also known as multiple lipoprotein-type hyperlipidemia; an inherited disorder where patients and their affected first-degree relatives can at various times manifest high cholesterol and high triglycerides. Levels of HDL cholesterol are often moderately decreased;
(4) Familial Defective Apolipoprotein B-100 is a relatively common autosomal dominant genetic abnormality. The defect is caused by a single nucleotide mutation that produces a substitution of glutamine for arginine which can cause reduced affinity of LDL particles for the LDL receptor. Consequently, this can cause high plasma LDL and total cholesterol levels;
(5) Familial Dysbetaliproteinemia, also referred to as Type III Hyperlipoproteinemia, is an uncommon inherited disorder resulting in moderate to severe elevations of serum TG and cholesterol levels with abnormal apolipoprotein E function. HDL levels are usually normal; and
(6) Familial Hypertriglyceridemia, is a common inherited disorder in which the concentration of plasma VLDL is elevated. This can cause mild to moderately elevated triglyceride levels (and usually not cholesterol levels) and can often be associated with low plasma HDL levels.
Risk factors in exemplary Secondary Hyperlipidemia include, but are not limited to, the following: (1) disease risk factors, such as a history of Type 1 diabetes, Type 2 diabetes, Cushing's syndrome, hypothyroidism and certain types of renal failure; (2) drug risk factors, which include, birth control pills; hormones, such as estrogen and corticosteroids; certain diuretics; and various β blockers; (3) dietary risk factors include dietary fat intake per total calories greater than 40%; saturated fat intake per total calories greater than 10%; cholesterol intake greater than 300 mg per day; habitual and excessive alcohol use; and obesity.
The terms “obese” and “obesity” refers to, according to the World Health Organization, a Body Mass Index (BMI) greater than 27.8 kg/m2 for men and 27.3 kg/m2 for women (BMI equals weight (kg)/height (m2). Obesity is linked to a variety of medical conditions including diabetes and hyperlipidemia. Obesity is also a known risk factor for the development of Type 2 diabetes (See, e.g., Barrett-Conner, E. Epidemol. Rev. (1989) 11: 172-181; and Knowler, et al. Am. J. Clin. Nutr. (1991) 53:1543-1551).
GeneralThe present invention derives from the discovery that compounds of Formula (I) are useful in treating or controlling a number of diseases associated with glucose metabolism, lipid metabolism and insulin secretion. More particularly, the compounds of the invention are useful in treating Type 2 diabetes, hyperinsulinemia, hyperlipidemia, hyperuricemia, hypercholesteremia, atherosclerosis, one or more risk factors for cardiovascular disease, Syndrome X, hypertriglyceridemia, hyperglycemia, obesity, eating disorders and suppressing appetite. Without intending to be bound by theory, it is considered that the compounds of Formula (I) operate via modulation of receptor interactions associated with one or more isoforms of PPAR. As a result, the compounds have utility in treating a variety of diseases states or conditions associated with PPAR.

Preparation of Compounds of the InventionThe compounds of the present invention can be prepared in a number of ways familiar to one skilled in the art of organic synthesis. The compounds outlined herein can be synthesized using methods generally outlined in Scheme 1, along with methods typically utilized by a synthetic chemist and combinations or variations of those methods, which are generally known to one skilled in the art of synthetic chemistry. The synthetic route of compounds in the present invention is not limited to the methods outlined below. It is assumed one skilled in the art will be able to use the schemes outlined below to synthesized compounds claimed in this invention. Individual compounds may require manipulation of the condition in order to accommodate various functional groups. A variety of protecting groups generally known to one skilled in the art may be required. Purification, if necessary can be accomplished on a silica gel column eluted with the appropriate organic solvent . Also, reverse phase HPLC or recrystallization may be employed.
The compounds of formula (I) can be prepared using methods generally outlined in Scheme 1
According to Scheme 1, electrophilic, aryl compounds of formula (I) (either commercially available or prepared according to known methods or methods outlined below in Scheme 3) are condensed with suitably substituted, nucleophilic aryl compounds ii generally in the presence of solvent and a non-nucleophilic base to provide target compound iii. Alternatively nucleophilic, aryl compounds of formula iv (either commercially available or prepared according to known methods or methods outlined below in Scheme 3) are condensed with suitably substituted, electrophilic aryl compounds v generally in the presence of solvent and a non-nucleophilic base to provide target compound iii. Examples of suitable non-nucleophilic bases include, but are not limited to, potassium carbonate, cesium bicarbonate, sodium hydride and the like.
The general synthesis schemes below are provided to illustrate the preparation of compounds of Formula (I) in which Z is a carboxylic acid or ester. For example, as shown in Scheme 2 aryl compounds vi (prepared as described below) are condensed with a substituted haloalkylether vii in the presence of cesium carbonate to provide target compounds viii. Similarly, aryl compounds ix (prepared as described below) are condensed with a substituted phenol x in the presence of cesium carbonate to provide target compounds viii. Compounds viii where R1 is halogen can be converted into the corresponding amino-substituted compounds xi (e.g. NR2=tetrahydroisoindoyl or 4-arylpiperidine) or alkynyl compounds xiii by treatment with an appropriately substituted amine or alkyne respectively. Compounds viii where R1 is a benzotriazole can be converted into the corresponding tetrahydrobenzotriazole compounds xii via hydrogenation. Treatment of the target esters viii, xi, xii and xiii (Z═CO2R) with lithium hydroxide converts the esters to carboxylic acid compounds viii, xi, xii and xiii (Z═CO2H).
As shown in Scheme 3, compounds of formula (I) wherein R1 is aryl can be prepared by treating 4-chloro-aryl compound xiv with 2-thiophene boronic acid to provide aryl substituted compounds, xv.
The synthesis of such aryl intermediates vi and ix is illustrated in Scheme 4 with intermediates in which Ar1 is a substituted benzene. Thus intermediates xix can be prepared by condensing substituted phenol Y2═O with a dihalo alkyl compound xviii . Functionality Z may be subsequently added by treatment of compound xvi with bromo-acetic acid ethyl ester in the presence of sodium hydride to provide the intermediate compound xix. Alternatively, functionality Z may be carried through as is shown with compound xx. Intermediate aryl compounds xix can be converted to the corresponding bi-aryl derivatives xvi with another substituted phenol such as 2-bromo-4-chloro-phenol. Conversion of compounds xxi to the further functionalized compounds is accomplished as noted in Scheme 2.
Alternatively as outlined in Scheme 5, compounds of formula xxii can be converted into intermediate xxiii by treatment with a dihaloalkyl compound to form haloalkylether derivative xxiii. This route is particularly useful to form intermediates of formula viii in Scheme 2 which have Ar2 rings functionalized with different R1 groups.
By using the methods outlined above, target compounds with linking groups of different lengths and functionality can be prepared. Thus, structural isomers, having the Y3 attached at either the 2- or 3-position relative to the phenol hydroxyl group in compound x can be prepared from the corresponding 2- or 3-mercaptophenols.
Still further, the general schemes outlined in Schemes 1-5 can be used to prepare compounds of Formula (I) in which Ar2 is another ring . To obtain these compounds, the phenols are replaced by the corresponding hydroxy-substituted ring .
Likewise, the general schemes outlined in Schemes 1-5 can be used to prepare compounds of Formula (I) in which L or K is an alternatively functionalized linking group. To obtain these compounds, mercapto phenols may be replaced with halo phenols or halothiophenols and the resulting halogenated aryl intermediates can be coupled with haloalkyl moieties to give alkyl linking groups.
Likewise, related compounds with different Ar1 and Ar2 rings and different lengths and substitution of linkers L and K can be prepared in a similar manner beginning with appropriately substituted aryl compounds many of which are available from commercial sources or can be prepared according to literature methods. More specific details are provided in the examples below. In each of Schemes 1-5, reaction conditions (e.g., amounts of reactants, solvents, temperatures and workup conditions) can be selected using the Examples below as a guide.
Preparation of Alcohols, Ethers, Nitrites, Amides/Imides and AldehydesThe above general synthesis schemes are provided to illustrate the prepared of compounds of Formula (I) in which Z is a carboxylic acid or ester. Conversion of each of these groups into the corresponding alcohols, ethers, nitriles, amides/imides or aldehydes can be accomplished using methods generally known to one of skill in the art. Several methods for reduction (and oxidation) are provided below as illustrative of the processes used in preparing additional compounds of the invention.
Conversion of Carboxylic Acids into Alcohols, Ethers, Nitrites, Amide/Imides and Aldehydes
The carboxylic acids of this invention can be converted into the corresponding alcohols, ethers, nitriles, amides/imides and aldehydes by a number of methods, including the routes A-D shown in Scheme 6. The method to be used in a given case depends on the nature of R and the substituents thereon. A variety of useful methods are described in Larock, COMPREHENSIVE ORGANIC TRANSFORMATIONS, VCH Publishers Inc, New York (1989). In particular, methods are described for converting acyl chlorides 32 to aldehydes 33 (p 620), esters 31 to aldehydes 33 (p 621), esters 31 to carbinols 35 (p 549), carboxylic acids 31 to carbinols 35 (p 548), esters 31 to amides/imides 34 (p 987) and esters 31 to nitriles 36 (p 988).
In method A, Scheme 6, a carboxylic acid 31 is first converted into the corresponding acid chloride 32. This transformation is effected by reacting the acid 31 with oxalyl chloride, phosphorus pentachloride or, preferably, thionyl chloride. The reaction is conducted in an aprotic solvent such as dichloromethane, tetrahydrofuran or, preferably, 1,2-dichloroethane. The acid chloride 32 is then converted into the aldehyde 33 by chemical reduction, such as by the use of sodium borohydride in DMF at −70° C., as described in Tetrahedron Lett. 22:11 (1981) or, more preferably by hydrogenation using 5% palladium on barium sulfate as catalyst (see, for example, J. Amer. Chem. Soc., 108:2608 (1986)). The reaction is conducted in an aprotic solvent such as toluene or, preferably, xylene. The aldehyde 33 is converted into the carbinol 35 by reduction, for example by reaction with 9 BBN, lithium aluminum tritertiarybutoxy hydride or more preferably sodium borohydride, (see, J. Amer. Chem. Soc. 71:122 (1949)). The reaction is conducted in a protic solvent such as ethanol or preferably, isopropanol.
Alternatively ester 31 can be converted directly into the aldehyde 3 by reduction, for example, by the use of sodium aluminum hydride or preferably, diisobutyl aluminum hydride (see e.g., Synthesis, 617 (1975)). The reaction is conducted in a non-polar solvent such as benzene or, preferably, toluene.
In method B, Scheme 6, ester 31 is converted into the amide/imide 34 by transesterification with hydroxypyridine and the corresponding amine (see, J.C.S.C. 89 (1969)). The reaction is conducted in an ethereal solvent such as dioxane or, preferably, tetrahydrofuran.
In method C, Scheme 6, ester 31 is converted into the carbinol 35 by reduction with lithium aluminum hydride or, preferably, with lithium borohydride (see, J. Amer. Chem. Soc., 109:1186 (1987)). The reaction is conducted in an ethereal solvent such as dioxane or, preferably, tetrahydrofuran.
Alternatively, carboxylic acid 31 can be converted into the carbinol 35. This conversion is effected by reacting the carboxylic acid with a reducing agent such as lithium aluminum hydride or, preferably, with diborane, as described in ORGANIC SYNTHESES, 64:104 (1985). The reaction is conducted in an ethereal solvent such as dioxane or, preferably, tetrahydrofuran.
The carbinol 35 (R6═H) can be converted into the ether 35 (R6═C1-C8). This transformation is effected by an alkylation reaction, for example by reacting the carbinol 35 with an alkyl chloride (C1-C8)Cl. The reaction is conducted in an aprotic solvent such as dichloromethane or, preferably, tetrahydrofuran, in the presence of an organic base such as triethylamine or, preferably, pyridine.
In method D, Scheme 6, the ester 31 is converted into the nitrile 36. This conversion is effected by reacting the ester with a dehydrating agent such as dimethylaluminum nitride as described in Tett. Lett., 4907 (1979).
Furthermore, the tetrazole derivatives may be conveniently prepared by a general process wherein a compound like 36 is coupled to an alcohol using the Mitsunobu protocol (Synthesis 1, (1981).
Not all compounds of formula I may be compatible with some of the reaction conditions described in the Examples. Such restrictions are readily apparent to those skilled in the art of organic synthesis and alternative methods must then be used.
Isomeric CompoundsCertain of the compounds of the present invention possess one or more chiral centers and each center may exist in the R or S configuration. The present invention includes all diastereomeric, enantiomeric and epimeric forms as well as the appropriate mixtures thereof. For many compounds of the present invention, a single chiral center is present (at the carbon atom bearing R2), resulting in racemic mixtures of enantiomers. As noted above, the present invention further includes compounds, compositions and methods wherein a single isomer (or single enantiomer) is provided or used. Methods of preparing chiral compounds are provided in the Examples. Alternatively, mixtures of enantiomers can be separated into their individual isomers via methods known in the art such as salt formation and crystallization with chiral bases, chiral chromatography (e.g., HPLC using commercially available columns for chiral resolution) and via methods such as simulated moving bed chromatography (see, for example, U.S. Pat. No. 5,518,625).

Pharmaceutical Compositions and Methods of Treating Diseases and ConditionsIn accordance with the present invention, a therapeutically effective amount of a compound of Formula (I) can be used for the preparation of a pharmaceutical composition useful for treating diabetes, treating hyperlipidemia, treating hyperuricemia, treating obesity, lowering triglyceride levels, lowering cholesterol levels, raising the plasma level of high density lipoprotein and for treating, preventing or reducing the risk of developing atherosclerosis.
The compositions of the invention can include compounds of Formula (I), pharmaceutically acceptable salts thereof or a hydrolysable precursor thereof. In general, the compound is mixed with suitable carriers or excipient(s) in a therapeutically effective amount. By a “therapeutically effective dose”, “therapeutically effective amount” or, interchangeably, “pharmacologically acceptable dose” or “pharmacologically acceptable amount”, it is meant that a sufficient amount of the compound of the present invention and a pharmaceutically acceptable carrier, will be present in order to achieve a desired result, e.g., alleviating a symptom or complication of Type 2 diabetes.
The compounds of Formula (I) that are used in the methods of the present invention can be incorporated into a variety of formulations for therapeutic administration. More particularly, the compounds of Formula (I) can be formulated into pharmaceutical compositions by combination with appropriate, pharmaceutically acceptable carriers or diluents and can be formulated into preparations in solid, semi-solid, liquid or gaseous forms, such as tablets, capsules, pills, powders, granules, dragees, gels, slurries, ointments, solutions, suppositories, injections, inhalants and aerosols. As such, administration of the compounds can be achieved in various ways, including oral, buccal, rectal, parenteral, intraperitoneal, intradermal, transdermal, intratracheal administration. Moreover, the compound can be administered in a local rather than ic manner, in a depot or sustained release formulation. In addition, the compounds can be administered in a liposome.
The compounds of Formula (I) can be formulated with common excipients, diluents or carriers and compressed into tablets or formulated as elixirs or solutions for convenient oral administration or administered by the intramuscular or intravenous routes. The compounds can be administered transdermally and can be formulated as sustained release dosage forms and the like. Compounds of Formula (I) can be administered alone, in combination with each other or they can be used in combination with other known compounds (see Combination Therapy below).
Suitable formulations for use in the present invention are found in Remington's Pharmaceutical Sciences (Mack Publishing Company (1985) Philadelphia, Pa., 17th ed.), which is incorporated herein by reference. Moreover, for a brief review of methods for drug delivery, see, Langer, Science (1990) 249:1527-1533, which is incorporated herein by reference. The pharmaceutical compositions described herein can be manufactured in a manner that is known to those of skill in the art, i.e., by means of conventional mixing, dissolving, granulating, dragee-making, levigating, emulsifying, encapsulating, entrapping or lyophilizing processes. The following methods and excipients are merely exemplary and are in no way limiting.
For injection, the compounds can be formulated into preparations by dissolving, suspending or emulsifying them in an aqueous or nonaqueous solvent, such as vegetable or other similar oils, synthetic aliphatic acid glycerides, esters of higher aliphatic acids or propylene glycol; and if desired, with conventional additives such as solubilizers, isotonic agents, suspending agents, emulsifying agents, stabilizers and preservatives. Preferably, the compounds of the present invention can be formulated in aqueous solutions, preferably in physiologically compatible buffers such as Hanks's solution, Ringer's solution or physiological saline buffer. For transmucosal administration, penetrants appropriate to the barrier to be permeated are used in the formulation. Such penetrants are generally known in the art.
For oral administration, the compounds of Formula (I) can be formulated readily by combining with pharmaceutically acceptable carriers that are well known in the art. Such carriers enable the compounds to be formulated as tablets, pills, dragees, capsules, emulsions, lipophilic and hydrophilic suspensions, liquids, gels, syrups, slurries, suspensions and the like, for oral ingestion by a patient to be treated. Pharmaceutical preparations for oral use can be obtained by mixing the compounds with a solid excipient, optionally grinding a resulting mixture and processing the mixture of granules, after adding suitable auxiliaries, if desired, to obtain tablets or dragee cores. Suitable excipients are, in particular, fillers such as sugars, including lactose, sucrose, mannitol or sorbitol; cellulose preparations such as, for example, maize starch, wheat starch, rice starch, potato starch, gelatin, gum tragacanth, methyl cellulose, hydroxypropylmethyl-cellulose, sodium carboxymethylcellulose and/or polyvinylpyrrolidone (PVP). If desired, disintegrating agents can be added, such as the cross-linked polyvinyl pyrrolidone, agar or alginic acid or a salt thereof such as sodium alginate.
Dragee cores are provided with suitable coatings. For this purpose, concentrated sugar solutions can be used, which can optionally contain gum arabic, talc, polyvinyl pyrrolidone, carbopol gel, polyethylene glycol and/or titanium dioxide, lacquer solutions and suitable organic solvents or solvent mixtures. Dyestuffs or pigments can be added to the tablets or dragee coatings for identification or to characterize different combinations of active compound doses.
Pharmaceutical preparations which can be used orally include push-fit capsules made of gelatin, as well as soft, sealed capsules made of gelatin and a plasticizer, such as glycerol or sorbitol. The push-fit capsules can contain the active ingredients in admixture with filler such as lactose, binders such as starches and/or lubricants such as talc or magnesium stearate and, optionally, stabilizers. In soft capsules, the active compounds can be dissolved or suspended in suitable liquids, such as fatty oils, liquid paraffin or liquid polyethylene glycols. In addition, stabilizers can be added. All formulations for oral administration should be in dosages suitable for such administration.
For buccal administration, the compositions can take the form of tablets or lozenges formulated in conventional manner.
For administration by inhalation, the compounds for use according to the present invention are conveniently delivered in the form of an aerosol spray presentation from pressurized packs or a nebulizer, with the use of a suitable propellant, e.g., dichlorodifluoromethane, trichlorofluoromethane, dichlorotetrafluoroethane, carbon dioxide or other suitable gas or from propellant-free, dry-powder inhalers. In the case of a pressurized aerosol the dosage unit can be determined by providing a valve to deliver a metered amount. Capsules and cartridges of, e.g., gelatin for use in an inhaler or insufflator can be formulated containing a powder mix of the compound and a suitable powder base such as lactose or starch.
The compounds can be formulated for parenteral administration by injection, e.g., by bolus injection or continuous infusion. Formulations for injection can be presented in unit dosage form, e.g., in ampules or in multidose containers, with an added preservative. The compositions can take such forms as suspensions, solutions or emulsions in oily or aqueous vehicles and can contain formulator agents such as suspending, stabilizing and/or dispersing agents.
Pharmaceutical formulations for parenteral administration include aqueous solutions of the active compounds in water-soluble form. Additionally, suspensions of the active compounds can be prepared as appropriate oily injection suspensions. Suitable lipophilic solvents or vehicles include fatty oils such as sesame oil or synthetic fatty acid esters, such as ethyl oleate or triglycerides or liposomes. Aqueous injection suspensions can contain substances which increase the viscosity of the suspension, such as sodium carboxymethyl cellulose, sorbitol or dextran. Optionally, the suspension can also contain suitable stabilizers or agents which increase the solubility of the compounds to allow for the preparation of highly concentrated solutions. Alternatively, the active ingredient can be in powder form for constitution with a suitable vehicle, e.g., sterile pyrogen-free water, before use.
The compounds can also be formulated in rectal compositions such as suppositories or retention enemas, e.g., containing conventional suppository bases such as cocoa butter, carbowaxes, polyethylene glycols or other glycerides, all of which melt at body temperature, yet are solidified at room temperature.
In addition to the formulations described previously, the compounds can also be formulated as a depot preparation. Such long acting formulations can be administered by implantation (for example subcutaneously or intramuscularly) or by intramuscular injection. Thus, for example, the compounds can be formulated with suitable polymeric or hydrophobic materials (for example as an emulsion in an acceptable oil) or ion exchange resins or as sparingly soluble derivatives, for example, as a sparingly soluble salt.
Alternatively, other delivery s for hydrophobic pharmaceutical compounds can be employed. Liposomes and emulsions are well known examples of delivery vehicles or carriers for hydrophobic drugs. In a presently preferred embodiment, long-circulating, i.e., stealth liposomes can be employed. Such liposomes are generally described in Woodle, et al., U.S. Pat. No. 5,013,556. The compounds of the present invention can also be administered by controlled release means and/or delivery devices such as those described in U.S. Pat. Nos. 3,845,770; 3,916,899; 3,536,809; 3,598,123; and 4,008,719.
Certain organic solvents such as dimethylsulfoxide (DMSO) also can be employed, although usually at the cost of greater toxicity. Additionally, the compounds can be delivered using a sustained-release , such as semipermeable matrices of solid hydrophobic polymers containing the therapeutic agent. Various types of sustained-release materials have been established and are well known by those skilled in the art. Sustained-release capsules can, depending on their chemical nature, release the compounds for a few hours up to over 100 days.
The pharmaceutical compositions also can comprise suitable solid or gel phase carriers or excipients. Examples of such carriers or excipients include but are not limited to calcium carbonate, calcium phosphate, various sugars, starches, cellulose derivatives, gelatin and polymers such as polyethylene glycols.
Pharmaceutical compositions suitable for use in the present invention include compositions wherein the active ingredients are contained in a therapeutically effective amount. The amount of composition administered will, of course, be dependent on the subject being treated, on the subject's weight, the severity of the affliction, the manner of administration and the judgment of the prescribing physician. Determination of an effective amount is well within the capability of those skilled in the art, especially in light of the detailed disclosure provided herein.
For any compound used in the method of the present invention, a therapeutically effective dose can be estimated initially from cell culture assays or animal models.
Moreover, toxicity and therapeutic efficacy of the compounds described herein can be determined by standard pharmaceutical procedures in cell cultures or experimental animals, e.g., by determining the LD50, (the dose lethal to 50% of the population) and the ED50 (the dose therapeutically effective in 50% of the population). The dose ratio between toxic and therapeutic effect is the therapeutic index and can be expressed as the ratio between LD50 and ED50. Compounds which exhibit high therapeutic indices are preferred. The data obtained from these cell culture assays and animal studies can be used in formulating a dosage range that is not toxic for use in human. The dosage of such compounds lies preferably within a range of circulating concentrations that include the ED50 with little or no toxicity. The dosage can vary within this range depending upon the dosage form employed and the route of administration utilized. The exact formulation, route of administration and dosage can be chosen by the individual physician in view of the patient's condition. (See, e.g., Fingl et al. 1975 In: The Pharmacological Basis of Therapeutics, Ch. 1).
The amount of active compound that can be combined with a carrier material to produce a single dosage form will vary depending upon the disease treated, the mammalian species and the particular mode of administration. However, as a general guide, suitable unit doses for the compounds of the present invention can, for example, preferably contain between 100 mg to about 3000 mg of the active compound. A preferred unit dose is between 500 mg to about 1500 mg. A more preferred unit dose is between 500 to about 1000 mg. Such unit doses can be administered more than once a day, for example 2, 3, 4, 5 or 6 times a day, but preferably 1 or 2 times per day, so that the total daily dosage for a 70 kg adult is in the range of 0.1 to about 250 mg per kg weight of subject per administration. A preferred dosage is 5 to about 250 mg per kg weight of subject per administration and such therapy can extend for a number of weeks or months and in some cases, years. It will be understood, however, that the specific dose level for any particular patient will depend on a variety of factors including the activity of the specific compound employed; the age, body weight, general health, sex and diet of the individual being treated; the time and route of administration; the rate of excretion; other drugs which have previously been administered; and the severity of the particular disease undergoing therapy, as is well understood by those of skill in the area.
A typical dosage can be one 10 to about 1500 mg tablet taken once a day or, multiple times per day or one time-release capsule or tablet taken once a day and containing a proportionally higher content of active ingredient. The time-release effect can be obtained by capsule materials that dissolve at different pH values, by capsules that release slowly by osmotic pressure or by any other known means of controlled release.
It can be necessary to use dosages outside these ranges in some cases as will be apparent to those skilled in the art. Further, it is noted that the clinician or treating physician will know how and when to interrupt, adjust or terminate therapy in conjunction with individual patient response.
Combination TherapyAs noted above, the compounds of the present invention will, in some instances, be used in combination with other therapeutic agents to bring about a desired effect. Selection of additional agents will, in large part, depend on the desired target therapy (see, e.g., Turner, N. et al. Prog. Drug Res. (1998) 51: 33-94; Haffner, S. Diabetes Care (1998) 21: 160-178; and DeFronzo, R. et al. (eds.), Diabetes Reviews (1997) Vol. 5 No. 4). A number of studies have investigated the benefits of combination therapies with oral agents (see, e.g., Mahler, R. J. Clin. Endocrinol. Metab. (1999) 84: 1165-71; United Kingdom Prospective Diabetes Study Group: UKPDS 28, Diabetes Care (1998) 21: 87-92; Bardin, C. W.,(ed.), C
