Description

ACIDS a- (TRIFLUOROMETHYL-ARILOXYL, ARILAMINO, ARILTIOL OR SUBSTITUTE ARILMETILE) -TRIFLUORO ETIL-PHENYLLACTIC SUBSTITUTES AND THEIR DERIVATIVES AS ANTIDIABETIC AGENTS BACKGROUND OF THE INVENTION Diabetes mellitus, commonly called diabetes, refers to a disease process derived from multiple causative factors characterized by elevated levels of plasma glucose, referred to as hyperglycemia. See, for example, LeRoith, D. Et al. , (editors), DIABETES MELLITUS (Lippincott-Raven Publishers, Philadelphia, PA E.Ü.A. 1996) and all the references cited here. According to the American Diabetes Association, diabetes mellitus is estimated to affect approximately 6% of the population in the world. Uncontrolled hyperglycemia is associated with premature increase and mortality due to the increased risk of microvascular and macrovascular diseases, including nephropathy, neuropathy, retinopathy, hypertension, cerebrovascular disease and coronary heart disease. Likewise, the control of glucose homeostasis is an important critical factor for the treatment of diabetes. There are two main types 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 that regulates the use of glucose. This insuin deficiency is generally characterized by the destruction of β-cells within the Islets of Langerhans in the pancreas, which usually results in an absolute deficiency of insulin. Type 1 diabetes has two forms: Immuno-Mediated Diabetes Mellitus, which results from autoimmune cell destruction mediated by pancreatic β-cells; and Idiopathic Diabetes Mellitus, which refers to forms of the disease that have unknown etiologies. Type 2 diabetes is a disease characterized by insulin resistance accompanied by a relative, rather than absolute, deficiency of insulin. Type 2 diabetes can be in the range from predominant insulin resistance with a relative insulin deficiency to a predominant insulin deficiency with some insulin resistance. Insulin resistance is the diminished capacity of insulin to exert its biological action through a wide range of concentrations. In individuals with insulin resistance, the body abnormally secretes large amounts of insulin to compensate for this defect. When inadequate amounts of insulin are present to compensate for insulin resistance and proper glucose control, the development of the glucose tolerance state worsens. In a significant number of individuals, insulin secretion also decreases and the plasma glucose level increases, resulting in the clinical state of diabetes. Type 2 diabetes can be due to a deep insulin resistance stimulating the regulating effects on the metabolism of glucose and lipids in the main insulin sensitive tissues: muscles, liver and adipose tissue. This resistance to insulin sensitivity results in insufficient activation of insulin for increased glucose, oxidation and storage in muscles and inadequate insulin recession of lipolysis in adipose tissue and production of glucose and secretion in the liver. In Type 2 diabetes, free fatty acid levels are often high in obese patients and certain non-obese patients, so lipid oxidation is increased. The premature development of atherosclerosis and the increased rate of cardiovascular and peripheral vascular diseases are characteristic types of patients with diabetes, where hyperlipidemia is an important factor that precipitates these diseases. Hyperlipidemia is a condition generally characterized by an abnormal increase in serum lipids and blood flow and as indicated above, is an important risk factor in the development of atherosclerosis and heart disease. For a review of lipid metabolism disorders, see for example, Wilson, J. Et al. , (editor), Disorders of Lipid metabolism, Chapter 23, Textbook of Endocrinology, 9th edition (W. B. Sanders Company, Philadelphia, PA E.U.A. 1998; this reference and all references cited here are incorporated by reference here). The serum lipoproteins are the carriers of lipids in the circulation. These 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 generally classified as primary or secondary hyperlipidemia. Primary hyperlipidemia is usually caused by genetic defects, while secondary hyperlipidemia is usually caused by other factors, such as various disease states, drugs, and dietary factors. Alternatively, hyperlipidemia may result from a combination of primary and secondary causes of hyperlipidemia. Elevated cholesterol levels are associated with a number of disease states, including coronary artery disease, angina pectoris, carotid artery disease, strokes, cerebral arteriosclerosis and xanthoma. Dyslipidemia or abnormal levels of lipoproteins in plasma saguinum is a frequent occurrence among diabetics and has been shown to be one of the main contributors to the incidence of disease in coronary events and deaths among diabetic individuals (see, for example, Joslin. Ann. Chim. Med. (1927) 5: 1061-1079). Epidemiological studies since the association has been confirmed and have shown a much greater increase in coronary death among diabetic individuals compared with non-diabetic individuals (see for example, García MJ et al., Diabetes (1974) 23: 105-11 (1974 ), and Laakso, M. and Lehto, S., Diabetes Reviews (1997) 5 (4): 294-315). Several lipoprotein abnormalities have been described among diabetic individuals (Howard B., et al., Artherosclerosis (1978) 30: 153-162). What is needed in the art are new components and methods useful for the treatment of insulin resistance, Type 2 diabetes, hyperlipidemia and hyperuricemia. The present invention meets this and other needs by providing these compounds, compositions and methods for improving insulin resistance, Type 2 diabetes, hyperlipidemia and hyperuricemia.

They have the same molecular formula but differ in the nature or bonding sequence of their atoms or the arrangement of their atoms in space are called "isomers." The isomers that differ in the arrangement of their atoms in space are called " stereoisomers. "The stereoisomers that do not reflect the image of each other are called" diastereomers "and those that do not superimpose reflected images of each other are called" enantiomers. "When a compound has an asymmetric center, for example, which is linked 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 Canh and Prelog or by the way in which the molecule rotates in the plane of polarized light and is designated as dextrogiratory or levogyratory (that is, as (+) or (-) -isomers, respectively). A chiral compound can exist either as a single enantiomer or as a mixture thereof. A mixture containing equal proportions of enantiomers is called a "racemic mixture." The compounds of this invention can exist in stereoisomeric form if they have one or more asymmetric centers or a double bond with asymmetric substitution and can therefore be produced as individual stereoisomers or as mixtures. Unless indicated otherwise, the disclosure is intended to include individual stereoisomers as well as mixtures thereof.

The term "prodrugs" means any compound that releases an active parent compound according to Formula 1 in vivo when the prodrug is administered to a mammalian subject. Prodrugs of a compound of Formula 1 are prepared by modifying the functional groups present in the compound of Formula 1 where a route allows the binding modifications in vivo to release the parent compound. Prodrugs include compounds of Formula 1 wherein a hydroxyl, amino or sulfhydryl group in a compound of Formula 1 is attached to any group that can be linked in vivo to regenerate the free, amino or sulfhydryl hydroxyl group, respectively. Examples of prodrugs include but are not limited to esters (e.g., acetate, formate and benzoate derivatives), amides, carbamates (e.g., N, N-dimethylaminocarbonyl) of hydroxyl functional groups in the compounds of Formula 1 and Similary. The term "protecting group" refers to a grouping of atoms that when they bind to a reactive group in a molecule masks, reduces or prevents this reactivity. Examples of protecting groups are found in T. W. Greene and P. G. Wuts, PROTECTIVE GROUPS IN ORGANIC CHEMISTRY (Wiley 2nd edition, 1991) and Harrison and Harrison et al. , COMPENDIUM OF SYNTHETIC ORGANIC METHODS, Volumes 1-8 (John Wiley and Sons, 1971-1996). Representative amino protecting groups include formyl, acetyl, trifluoroacetyl, benzyl, benzyloxycarbonyl (CBZ), tert-butoxycarbonyl (Boc), trimethylsilyl (TMS), 2-trimethylsilyl-ethanesulfonyl (SES), trityl and substituted trityl groups, alkyloxycarbonyl, 9- Fluorenylmethyloxycarbonyl (FMOC), nitro-veratriloxycarbonyl (NVOC) and the like.

With reference to the methods of the present invention, the following terms are used with the notorious meaning: The terms "treat" or "treatment" of a disease include: (1) preventing the disease, that is, causing the clinical symptoms of the disease does not develop in a mammal that may be willing or predisposed to the disease but that does not produce experiences or shows symptoms of disease, (2) inhibit the disease, that is, enclose or reduce the development of disease or its clinical symptoms, or (3) relieving the disease, that is, causing regression of the disease or its clinical symptoms. The term "therapeutically effective amount" means the amount of the compound of the subject that will release the medical or biological response from a tissue, system, animal or human that is sought by the researcher, veterinarian, doctor or other clinician. A "therapeutically effective amount" includes the amount of a compound that when administered to a mammal to treat a disease, is sufficient to effect such treatment for the disease. The "therapeutically active amount" may vary depending on the compound, the disease and its severity, as well as age, weight, etc., of the mammal to be treated. The term "mammal" includes without limitation, humans, domestic animals (for example, dogs or cats), farm animals (cows, horses or pigs), monkeys, rabbits, mice and laboratory animals. The term "insulin resistance" can be defined in general as a disorder in the metabolism of glucose. More specifically, insulin resistance can be defined as the diminished ability of insulin to exert its biological action over a wide range of concentrations producing less biological effect than expected. (See for example, Reaven, G. M., J. Basic &; Clin. Phys. & Pharm. (1998) 9: 387-406 and Flier, J. Am. Rev. Med. (1983) 34: 145-160). People with insulin resistance have a decreased ability to metabolize glucose properly and respond poorly, at all, to insulin therapy. Manifestations of insulin resistance include insufficient insulin activation due to increased glucose, oxidation and stored in muscles and inadequate insulin repression of lipolysis in adipose tissue and glucose production and secretion in the liver.
Insulin resistance can cause or contribute to polycystic ovary syndrome, impaired glucose tolerance (IGT), gestational diabetes, hypertension, obesity, atherosclerosis and a variety of other disorders. Eventually, individuals with insulin resistance can progress to a point where a diabetic state is reached. The association of insulin resistance with glucose intolerance, an increase in plasma triglycerides and a reduction in high density lipoprotein cholesterol concentrations, high blood pressure, hyperuricemia, dense low density lipoprotein particles and high levels of inhibitor- 1 plasminogen activator in the circulation, have been referred to as "Syndrome X" (see for example, Reaven, GM, 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 the production and utilization of glucose which results in failure to maintain adequate blood sugar levels in the body. The result of these defects is high blood sugar, 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 that regulates glucose utilization. Type 2 diabetes often occurs under normal conditions or with high insulin levels and may result in the inability of tissues to respond adequately to insulin. Many patients with Type 2 diabetes are insulin resistant and have a relative insulin deficiency, while 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 glucose homeostasis disorders include Tolerance to Impaired Glucose, which is an intermediate metabolic state between normal glucose homeostasis and diabetes and gestational diabetes mellitus, which is glucose intolerance during pregnancy in women who have no prior history of Type 1 or Type 2 diabetes. The term "secondary diabetes" is diabetes that results from other identifiable etiologies that include: genetic defects in β-cell function (eg, maturity of diabetes attacks during youth, referred to as "MODY", which is an early form of attack of Type 2 diabetes with autosomal inheritance, see for example, Fajans S. et al., Diabet Med. (1996) (9 Supplement 6): S90-5 and Bell, G. Et al., Annu Rev. Physiol. (1996) 58: 171-86, genetic defects of insulin action, diseases of the exocrine pancreas (for example, hemochromatosis, pancreatitis and cystic fibrosis), certain diseases and ndocrines where excess hormones interfere with the action of insulin (eg, hormonal development in acromegaly and cortisol in Cushing's syndrome); certain drugs that suppress insulin secretion (eg, phenytoin) or inhibit the action of insulin (eg, estrogen and glucocorticoids) and diabetes caused by infection (eg, rubella, Coxsackie, and CMV); as well as other genetic syndromes. Guidelines for the diagnosis of type 2 diabetes, impaired glucose tolerance and gestational diabetes have been profiled by the American Diabetes Association (see, for example, The Expert Committee on the Diagnosis and Classification of Diabetes Mellitus, Diabetes Care (1999) Volume 2 (Supplement 1): S5-19). The term "hyperinsulinemia" refers to the presence of an abnormally high 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 high level of lipids in the blood. Hyperlipidemia can appear in at least three forms: (1) hypercholesterolemia, that is, an elevated cholesterol level; (2) hypertriglyceridemia, that is, an elevated level of triglycerides and (3) combined hyperlipidemia, that is, a combination of hypercholesterolemia and hypertriglyceride, mia. The term "secretagogue" means a substance or compound that stimulates secretion. For example, an insulin secretagogue is a substance or compound that stimulates insulin secretion. The term "hemoglobin" or "Hb" refers to a respiratory pigment present in erythrocytes, which is primarily responsible for the transport of oxygen. A hemoglobin molecule comprises four polypeptide subunits (two a-chain systems and two β-chain systems, respectively). Each subunit is formed by the association of a globin protein and a heme molecule that is a complex of protoporphyrin-iron. The main class of hemoglobin appears in the normal adult hemolysed (referred to as "HbA", also referred to as HbAO to distinguish it from the glycated hemoglobin, which is referred to as "HbAl", described infra) which has subunits < 22? 2. Trace components such as HbA2 (a2d2) can also appear in the normal adult homoling. Among the hemoglobin classes of adult HbA, there is a glycated hemoglobin (referred to as "HbAi" or "glycosylated hemoglobin"), which can also be fractionated into HbA? Al, HbA? A2, H ib and HbAlc with a fractionation of ion exchange All these subclasses have the same primary structure, which is stabilized by the formation of an aldimine (Schiff base) by the amino group of the N-terminal valine in the ß-chain subunit of normal hemoglobin HbA and glucose (or glucose-6) -phosphate or fructose) followed by the formation of ketoamine by the Amadori rearrangement. The term "glycosylated hemoglobin" (also referred to as "HbA? C", "GHb", "hemoglobin-glycosylated", "Diabetic control index" and "glycohemoglobin", referred to herein as "hemoglobin Ale") refers to the stable product of the non-enzymatic glycosylation of the β chain of hemoglobin by plasma glucose. Hemoglobin A? C comprises the major portion of hemoglobins glycated in the blood. The proportion of glycosylated hemoglobin is proportional to the blood glucose level. Therefore, the proportion of hemoglobin Alc formation increases directly with the increase in plasma glucose levels. Since glycosylation occurs at a constant rate during the 120-day life cycle of an erythrocyte, the quantification of glycosylated hemoglobin levels reflects the average blood glucose level for an individual during the preceding two to three months. Therefore, the determination of the amount of glycosylated hemoglobin HbAlc can be a good index for the control of carbohydrate metabolism. Accordingly, the blood glucose levels of the last two months can be estimated based on the proportion of HbAlc for the total hemoglobin Hb. The analysis of hemoglobin A? C in blood is used as a quantification that enables long-term control of the blood glucose level (see for example, 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 use. For example, "polyuria" means the passage of a large volume of urine during a given period; "polydipsia" means chronic and excessive thirst; and "polyphagia" • means excessive feeding. Other symptoms of diabetes include, for example, increasing susceptibility to certain infections (especially fungal and staphylococcal infections), nausea, and ketoacidosis (increased 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 that usually result in small damage to blood vessels. These complications include, for example, retinopathy (worsening or loss of vision due to damage of blood vessels in the eyes); neuropathy (nerve damage and pems in the feet due to damage to the blood vessels of the nervous system); and nephropathy (kidney disease due to damage to blood vessels in the kidneys). Macrovascular complications are those complications that generally result in more damaging blood vessels. These complications include, for example, cardiovascular disease and peripheral vascular disease. Cardiovascular disease is redirected to diseases of blood vessels of the heart. See, for example, Kaplan, R. M. et al. , "Cardiovascular diseases" in HEALTH AND HUMAN BEHAVIOR, pp. 206-242 (McGraw-Hill, New York 1993). Cardiovascular disease is in general one of several forms including, for example, hypertension (also referred to as high blood pressure), coronary heart disease, blockage and rheumatic heart disease. Peripheral vascular disease refers to diseases of any of the outer blood vessels of the heart. It is in general a narrowing of the blood vessels that carry blood to the muscles of the legs and arms. The term "atherosclerosis" encompasses vascular diseases and conditions that are recognized and understood by practicing physicists 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 blood vessel disease are all clinical manifestations of atherosclerosis and are therefore encompassed in terms of "atherosclerosis" and "atherosclerotic disease". The term "antihyperipidemic" refers to the reduction of excessive concentrations of blood lipids to desired levels. Similarly, the term "antiuricemic" refers to the reduction of excessive levels of uric acid in blood to the desired levels. The term "modulated" refers to the treatment, prevention, suppression, enhancement or induction of a function or condition. For example, the compounds of the present invention can modulate hyperlipidemia by reducing cholesterol in a human, and thereby suppress hyperlipidemia. The term "triglyceride (s)" ("TG") as used herein, incorporates their common use. TG consists of three molecules of fatty acids esterified for a glycerol molecule and are used to store fatty acids that are used by muscle cells for the production of energy or are raised and stored in the adipose tissue. Because cholesterol and TG are insoluble in water, they can 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 poor withdrawal. There are at least five different lipoproteins that differ in size, composition, density and function. In the small cells of the intestine, the lipids of the diet are packaged in large lipoprotein complexes called "chylomicrons", which have a high TG content and low cholesterol content. In the liver, Tg and cholesterol esters are packaged and released into the plasma as TG rich in lipoproteins known as very low density lipoproteins ("VLDL"), whose primary function is the endogenous transport of TG carried out in the liver or released by adipose tissue. Through the enzymatic action, VLDL can either be reduced and taken by the liver, or transformed into intermediate density lipoproteins ("IDL"). The IDL is in turn either taken by the liver or is also modified to form low density lipoproteins ("LDL"). LDL are either taken and degraded by the liver or taken by extrahepatic tissue. High density lipoproteins ("HDL") help remove cholesterol from peripheral tissues known as reverse cholesterol transport. The term "dyslipidemia" refers to abnormal levels of lipoproteins in blood plasma that include both depressed and / or elevated lipoprotein levels (e.g., elevated levels of LDL, VLDL and depressed levels of HDL). Exemplary Primary Hyperlipidemis includes but is not limited to the following: (1) Familial Hyperchlomicronemia, a rare genetic disorder that causes deficiencies in an enzyme, LP lipase, which degrades fat molecules. LP lipase deficiency can cause the accumulation of large amounts of fat or lipoproteins in the blood; (2) Familial hypercholesterolemia, a relatively common genetic disorder caused where the underlying effect is a series of mutations in the LDL receptor gene that results in a malfunction of LDL receptors and / or absence of LDL receptors. This causes the ineffective performance of LDL by LDL receptors that result in high LDL and total cholesterol levels in the plasma; (3) Combined familial hyperlipidemia, also known as multiple lipoprotein hyperlipidemia; an inherited disorder where patients and their relatives affected in the first degree can manifest in several periods of time high levels of cholesterol and triglycerides. HDL cholesterol levels are generally moderately reduced; (4) Family Defective Apolipoprotein B-100 is a relatively common autosomal dominant genetic abnormality. The defect is caused by the mutation of a single nucleotide that produces a substitution of glutamine by arginine that can cause a reduced affinity of LDL particles for the LDL receptor. Consequently, this can cause high plasma LDL levels and total cholesterol levels. (5) Familial dysbetaliproteinaemia, also referred to as type III hyperlipoproteinemia, is a rare inherited disorder that results in moderate to severe increases in serum TG as well as cholesterol levels with abnormal functioning of apolipoprotein E. HDL levels are generally normalees; and (6) Familial Hypertriglyceridemia, is a common inherited disorder where the concentration of VLDL in plasma is high. This can cause medium to moderately elevated triglyceride levels (and usually without cholesterol levels) and can often be associated with low plasma HDL levels. The risk factors in Hyperlipidemia Secondary exemplified 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 pills to control breathing; hormones such as estrogen and corticosteroids; certain diuretics and several β-blockers; (3) risk factors in the diet that include the intake of fats in the diet by total calories greater than 40%; saturated fat intake by total calories greater than 10%; cholesterol intake greater than 300 mg per day; excessive and habitual use of alcohol; and obesity. The terms "obese" and "obesity" refer, according to the World Health Organization, to a Body Mass Index (BMI) greater than 27.8 kg / m2 for men and 27.3 kg / m2 for women (BMI is equivalent to weight (kg ) / height (m2)). Obesity is related 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, for example, Barrett-Conner, E., Epidemiol, Rev. (1989) 11: 172-181, and Knowler et al., Am. Clin Nutr. (1991) 53: 1543-1551). The terms "optional" or "optionally" as used throughout the specification mean that the subsequently described event or circnstacia may but not necessarily occur and that the description includes instances where the event or circumstance occurs and instances where it does not occur. For example, "a heterocycle group optionally mono- or di-substituted with an alkyl group" means that the alkyl may not necessarily be present and the description includes situations where the heterocycle group is mono- or di-substituted with an alkyl group and situations where the Heterocycle group is not substituted with the alkyl group.
General Description The present invention derives from the initial disclosure that phenylacetic (phenoxy) and acid (pyridyloxy) phenylacetic acids and their analogs, have a trifluoromethyl substitute in each of the aromatic rings, are extremely effective for the treatment of Type II diabetes and related metabolic disorders.

The preparation of Compound 1 wherein Y is tetrazole is shown in Reaction Schemes lf, lg. Compounds 1 wherein Y = C00Rc and Rc is H can be converted to compounds 1 wherein Rc is alkyl or aralkyl using conventional esterification methods, for example as described in Organic Chemistry Preparatory for R. B. Wagner and H. D. Zook, Wiley, p. 479 Reaction Scheme 1 - Preparation of Compounds 1 - |, Y = OCORc Reaction Scheme 1 - preparation of Compounds 1 (continued) ol 1 Y = COOH 1, Y = tetrazole Displacement of benzylic bromides with nucleophilic acids As illustrated in Reaction Scheme 1, bromo-esters 2 are reacted with the phenols, amines or mercaptans 3, to provide the products 1. The reaction is carried out in a polar aprotic solvent as tetrahydrofuran or, preferably, dimethylformamide in the presence of a base such as diazabicyclononene or preferably potassium carbonate. The products 1 wherein X is NH can be converted into products where N is acylated by a conventional acylation reaction, for example by reaction with an acyl chloride or anhydride in a basic solvent such as pyridine.
Displacement of fluorine substitutes with f-enylacetic ester ucleophiles Reaction Scheme Ib illustrates the synthesis of products 1 by the reaction displacement of a fluorine atom. The carbinoles, mercaptans or amines 4, X = 0, S, NH or N-alkyl are reacted with a portion of benzene or pyridine substituted with fluorine 5. In this reaction, the substrates 4 are first converted into an alkali metal salt, by treatment with a base such as sodium hydride or sodium hexamethyldisilazide. The reaction is carried out in an aprotic polar solvent such as tetrahydrofuran or dimethylformamide. The aryl fluoride 5 is then added and the reaction proceeds to provide the products, X = 0, S, NH or N-alkyl.
Condensation reactions of aldehydes 7 with phenylacetic esters 6 The reaction scheme illustrates the synthesis of compounds 1 wherein X is C. In this process, the tert-butyl esters 6 are first reacted with a base such as sodium hydride, in an aprotic solvent such as dimethylformamide. The generated anion is reacted with the aldehydes 7. After the dehydration, the unsaturated products are obtained 8. These compounds are converted into the products 1, X = C, by means of catalytic hydrogenation using for example 5% of palladium on carbon as a catalyst Alkylation reactions to introduce substitutes R2 Reaction Scheme ld illustrates the introduction of the alkyl substitutes R2 by means of an alkylation reaction. In this process, the esters 1 ase react first with a base such as sodium hydride or sodium hexamethyldisilazide in an aprotic solvent such as tetrahydrofuran or dimethylformamide. The alkylating agents R2Br or R2I are then added and the reaction proceeds to provide the ester products 1, where Y is carboxylic ester and R2 is alkyl. Basic hydrolysis, for example, by the use of lithium hydroxide in aqueous tetrahydrofuran, provides carboxylic acids 1 where R2 is alkyl.
Preparation of the aldehyde and carbinol derivatives 1 The Reaction Scheme illustrates the methods for preparing compounds 1 wherein Y is CHO, CH2OH and CH2OCO-alkyl. The compounds 1, Y = COOH are first converted to acid chlorides 9, by reaction with oxalyl chloride or preferably thionyl chloride. The acid chlorides 9 are then hydrogenated in the presence of a 5% palladium on barium carbonate catalyst, as described in Journal of the American Chemical Society, 79: 252 (1956). The latter compounds are converted to the corresponding carbinols 1, Y = CH 2 OH, by means of a reduction reaction, for example by treatment with sodium borohydride in ethanol or isopropanol. The products 1 Y = CH 2 OH are converted to esters 1, Y = CH 2 OCO-alkyl, by means of acylation reactions, for example by reaction with acetyl chloride in a basic solvent such as pyridine.
Preparation of tetrazole derivatives 1 The Scheme. Reaction lf illustrates methods for preparing compounds 1 where Y is tetrazole. The bromonitriles 10 are reacted with phenols, amines or mercaptans 3m to provide intermediate 11. The reaction is carried out in a polar aprotic solvent such as tetrahydrofuran or preferably dimethylformamide in the presence of a base such as diazabicyclononene or preferably carbonate of potassium. The intermediate 11 is then converted to the tetrazole with an azide or preferably with trimethyltin azide. Alternatively, intermediate 11 can be prepared from compound 1 (Y = COOH) by first transforming the acid into an amide after dehydration (Reaction Scheme lg).
Reaction Scheme 2 - Preparation of Phenylacetic Acid Intermediates F-enylacetic acid and phenylacetonitrile raw materials for the preparation of compounds 1 Many differently substituted phenylacetic acids and precursors thereof are commercially available or are described in the literature. In addition, a number of synthetic routes are available to prepare compounds that have not been previously reported. Reaction Scheme 2 shows some synthetic routes for the variously substituted phenylacetic acids and derivatives thereof. Reaction Scheme 2a illustrates the reaction of Arndt-Eistert, as described in Journal of the American Chemical Society, 72: 5163 (1950), while variously substituted benzoic acids can be transformed into the corresponding phenylacetic acids. In this process, the benzoic acid is first converted to the acid chloride by treatment with oxalyl chloride or thionyl chloride. The acid chloride is then reacted with an excess of diazomethane and the resulting diazoketone is rearranged by treatment with a silver salt, for example silver benzoate, under reflux in an alcohol such as methanol, to provide the corresponding ester of product 13. The Free acid 13 can also be obtained by basic hydrolysis. Alternatively, the ester of 13 can be alkylated, for example by treatment with a strong base such as lithium diisopropylamide, followed by a reaction with a halide R2X, to then provide by basic hydrolysis the alkylated phenylacetic acids 14. Reaction Scheme 2b illustrates the conversion of various bromobenzenes to the corresponding phenylacetic, phenylpropionic, etc., acids. In this process, the substituted bromobenzene is first reacted with magnesium in an ethereal solvent such as tetrahydrofuran, to form the Grignard reagent. An equimolar amount of anhydrous zinc chloride is then added, followed by the addition of ethyl bromoacetate to provide, after basic hydrolysis, the suitably substituted phenylacetic acid, R 2 = H. The compounds 6 wherein R 2 is methyl, ethyl, etc. , can be obtained by employing ethyl 2-bromopropionate or ethyl 2-bromobutyrate, etc., in place of ethyl bromoacetate. Reaction Scheme 2c illustrates the conversion of various substituted benzaldehydes into the a-bromophenylacetic acid feeders. In this procedure described in Synthetic Communications, 12: 763 (1982), benzaldehyde is first reacted with trimethylsilylcyanide in the presence of potassium cyanide and a crown ether to provide the corresponding substituted 17- (trimethylsilyloxy) phenylacetonitriles. These products are then subjected to treatment with an alcohol in the presence of an acid catalyst to produce the α-hydroxyphenylacetic esters 18. The reaction of the latter compounds is carried out with a brominating agent such as triphenylphosphine / carbon tetrabromide as described in US Pat. Tetrahedron Letters, 28: 3225 (1987), providing the bromoesters 19. Reaction Scheme 2d illustrates the conversion of various substituted a-hydroxyphenylacetic esters into the corresponding esters a-bromo and a-mercaptofenylacetic 20 and 4, X = S. In this process, the α-hydroxyphenylacetic esters 4 are converted first to the corresponding a-bromoesters, as described above. The bromo-esters 20 are then reacted with a sulfur nucleophile as sodium thiolacetate to provide the corresponding a-mercaptophenylacetic esters 4, X = S. Reaction Scheme 2e illustrates alternative methods for preparing the a-bromo and a-mercapto-phenylacetic esters 23 and 4, X = S, of the corresponding phenylacetic acids 14. In this process, the acids 14 are first treated with bromide and thionyl chloride to provide the acid chlorides of α-bromine 21. in the treatment with an alcohol, these compounds are converted to a-bromophenylacetic esters 23. Alternatively, phenylacetic acids 14 are first converted to esters 22, using conventional esterification methods. The esters 22 are then reacted with a brominating agent such as bromide or N-bromosuccinimide to provide the a-bromophenylacetic esters 23. These compounds can be transformed into the a-mercaptophenylacetic esters 4, X = S, as previously described. All phenylacetic acids can be converted to the corresponding phenyl acetonitriles by conventional transformations (see Reaction Scheme ig).
Reaction Scheme 3 - Preparations and interconversions of phenols, amines, mercaptans and aldehydes Raw materials of phenol, thiol, amine and aldehyde for the preparation of the compounds 1 Many phenols, thiols, amines and aldehydes required for the preparation of the compounds of this invention are commercially available or have been described in the literature. In addition, a number of synthetic routes are available to prepare compounds that have not been previously made. In Reaction Scheme 3 some synthetic routes for, and interconversions between the compounds are shown. Route A represents the synthesis of phenols from the corresponding bromide compounds 24. In this route, the bromide compound is first converted into an organolithium or organomagnesium derivative, respectively, by reaction with an alkyl lithium as n- Butyl-lithium or with metallic magnesium. Compound 25 is then converted to phenol 26 either by direct oxidation using, for example, molybdenum pentoxide as described in Journal of Organic Chemistry, 42: 1479 (1979), or by reaction first with a trialkylborate followed by oxidation with hydrogen peroxide as described in Journal of Organic Chemistry, 24: 1141 (1959). Route B represents the conversion of bromide compounds 24 directly to phenols 26 or thiophenols 28. This reaction proceeds in the case of particularly reactive bromide compounds, for example 2- or 4-bromopyridines (24, Y = N). The reaction can be effected by treatment of the bromopyridine with an aqueous acid or base as described in Rec. Trav. Chim. , 59: 202 (1940). The thiols corresponding to 26 are produced by reacting the bromide reactive compound with sodium sulfide in an alcohol solvent such as ethanol, as described in Rec. Trav. Chim. , 64: 102 (1945). Route C represents the conversion of a phenol 26 into the corresponding thiol 27. In this procedure described in Journal of Organic Chemistry, 81: 3980 (1966), the phenol is first reacted with dimethylthiocarbamoyl chloride, to provide the intermediate thiocarbamate. , where the thermal rearrangement after basic hydrolysis provides thiol 29. Route D represents the preparation of phenols 26 and cyano 31 compounds from the corresponding amine by the diazotization procedure as described in Organic Syntheses, Collective volume 3 , 130, 1955. In this reaction, the amine is reacted with nitrous acid to provide the diazonium salt where the acid hydrolysis produces phenol 26. Alternatively, the diazonium salt can be reacted with cuprous cyanide or nickel cyanide as described above. describes in Organic Functional Group Preparations, by SR Sandler and W. Karo, Academic Press, New York, p. 463 to provide the cyano compound 31. The cyano compound is useful for the preparation of the corresponding aldehyde 7. The E route represents the conversion of the fluorine compound to either the phenols 26, the thiols 28 or the amines 29. In this process , the fluorine compound is reacted with for example, sodium methoxide to provide the corresponding substituted methoxyl product. The methoxyl group is then removed using for example boron tribromide or aluminum chloride to provide the phenol 26. Alternatively, the fluorine compound 5 is reacted with a nitrogen nucleophile such as, for example, sodium azide to provide the corresponding azidobenzene. The reduction of the azido group, for example, by the use of lithium aluminum hydride, provides the amino compound 29. The thiols 28 are obtained by the reaction of the fluorine compounds with a sulfur nucleophile, for example with ethanolic sulfide. sodium. Route F represents the conversion of carboxylic acids 30 to amines 29 by means of rearrangement of Curtius as described in Organic Syntheses, Collective Volume 4, 819, 1963. In this procedure, the carboxylic acid is first converted to the acid chloride by reaction with thionyl chloride. The acid chloride is subjected to treatment with sodium azide to provide the acylazide, where the term rearrangement is carried out in aqueous solution to provide the amines 29. The G route represents the conversion of the carboxylic acids 30 into aldehydes 7 by means of the corresponding nitrile 31. The conversion of carboxylic acids 30 into nitriles 31 can be carried out in a number of routes, as described in Comprehensive Organic Transformations, by RC Larock, VCH Publishers, 1989, p. 963ff. For example, the carboxylic acid can first be converted to the acid chloride and the latter compound is then reacted with ammonia to provide the corresponding amide. Treatment of the amide with, for example, p-toluenesulfonyl chloride in pyridine then produces the nitrile 31. The nitrile can then be reduced to produce the aldehyde 7, for example by using diisobutylaluminum hydride as described in Journal of the American Chemical Society , 107: 7524 (1985). Route H represents the conversion of carboxylic acids 30 to the corresponding aldehydes. This conversion can be carried out on a number of routes as described in Comprehensive Organic Transformations by R. C. Larock, VCH Publishers, 1989, p. 619ff. For example, the carboxylic acid can first be converted to the acid chloride as described above. The latter compound can then be hydrogenated using a palladium catalyst on barium carbonate as described in Journal of the American Chemical Society, 108: 2608 (1986), or by reduction using lithium aluminum tri-butoxy-tertiary hydride, as described in Journal of the American Chemical Society, 79: 252 (1956) to produce the aldehydes 7.
Reaction Scheme 4 - Examples of protection and deprotection Desprnteger Protection and deprotection of reactive groups during synthesis Derivatives of phenylacetic acid 2, 4 and 6 can contain reactive groups such as IH, SH and NH2 that can generate undesired reactions during synthetic procedures. These groups may, according to the judgment of the person skilled in the art, require protection before a given synthetic step and deprotection after the synthetic step. Reaction scheme 4 shows examples of protection and deprotection. The selection, binding and removal of protective groups are described, for example, in PROTECTIVE GROUPS IN ORGANIC SYNTHESIS, by TW Greene and PGM Wuts, Wiley, 1991. Reaction Scheme 4a illustrates the protection of a derivative of phenylacetic acid substituted by a hydroxyl 32. The compound is reacted with tert-butylchlorodimethylsilane in the presence of imidazole to produce the silyl ether 33. After the reaction, as described above with intermediate 3, the protected product 34 is provided, the protecting group is removed by treatment with tetrabutylammonium fluoride to produce the final product 1. Silylation / desilylation processes are described in PROTECTIVE GROUPS IN ORGANIC SYNTHESIS, by TW Greene and PGM Wuts, Wiley, 1991, p. 145 Reaction Scheme 4b illustrates the protection of a mercapto-substituted phenylacetic acid derivative. The compound is reacted with 4-methoxybenzyl chloride to produce the thioether 35. This compound is reacted as described above with the intermediate 5 to produce the coupled product 36. The deprotection is carried out using mercuric acetate in trifluoroacetic acid which then provides the final product 1. the benzylation / debenzylation procedures are described in PROTECTIVE GROUPS IN ORGANIC SYNTHESIS, by TW Greene and PGM Wuts, Wiley, 1991, p. 281. Reaction Scheme 4c illustrates the protection of an amino-substituted phenylacetic acid derivative. The compound is reacted with tert-butoxycarbonyl chloriro to produce the carbamate 37. After condensation with the aldehyde 7 as described above and the subsequent dehydration / hydrogenation steps, intermediate 36 is obtained. The deprotection is carried out performed using trifluoroacetic acid which provides the final product 1. Silylation / desilylation processes are described in PROTECTIVE GROUPS IN ORGANIC SYNTHESIS, by TW Greene and PGM Wuts, Wiley, 1991, p. 327 Preparation of individual enantiomers of the compounds 1 The individual enantiomers of those compounds 1 can be separated by a variety of methods well known to those skilled in the art, for example, the racemic carboxylic acids 1 can be converted into salts with a chiral amine, such as for example, quinine, cinchonidine and the like. Fractional crystallization of the resulting salt, followed by release of the redissolved acids then provides the chiral compound 1. Alternatively, the chiral carboxylic acids can be converted to amides from chiral amines such as, for example, (R) or (S) 1-phenylethylamine. The resulting diastereomeric amides can then be separated by chromatography and the chiral acids regenerated by idolysis. Alternatively, the racemic compounds 1 can be separated into individual enantiomers by chiral HPLC. In addition, the racemic phenylacetic acid precursors of compounds 1 can be separated into individual enantiomers by using, for example, the methods described above before the formation of compounds 1.

The compounds can be administered transdermally and can be formulated as a sustained release dosage form and the like. The compounds of Formula 1 can be administered alone, in combination with one another or can be used in combination with other known compounds (see Combination Therapy below). Formulations suitable for use in the present invention are found in Remington's Pharmaceutical Sciences (Mark Publishing Company (1985) Philadelphia, PA, 17th edition), which is incorporated herein by reference. Furthermore, for a brief review of drug delivery methods, see Langer, Science (1990) 249: 1527-1533, which is incorporated herein by reference. The pharmaceutical compositions described herein can be manufactured in a manner known to the person skilled in the that is, by conventional mixing, dissolving, granulating, dragee-making, levigating, emulsifying, encapsulating, entrapping or lyophilizing processes. The following methods and excipients are merely exemplary and do not limit the paths. For injection, the compounds may be formulated into preparations upon dissolving, suspending or emulsifying them in an aqueous or non-aqueous solvent, such as vegetable or other similar oils, synthetic aliphatic acid glycerides, higher aliphatic acid esters 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 Hank's solution, Ringer's solution or physiological saline buffer. For transmucosal administration, appropriate penetrants are used to the barrier to make it permeable. These penetrants are generally known in the art. For oral administration, the compounds of formula 1 can be rapidly formulated by combining them with pharmaceutically acceptable carriers that are well known in the art. These carriers allow the compounds to be formulated as tablets, lozenges, lozenges, capsules, emulsions, lipophilic and hydrophilic suspensions, liquids, gels, syrups, mixtures, suspensions and the like, for oral ingestion by a patient undergoing treatment. Pharmaceutical preparations for oral use can be obtained by mixing the compounds with a solid excipient, optionally grinding a resulting mixture and processing the granule mixture, after adding suitable auxiliaries, if desired, to obtain tablets or dragee centers. Suitable excipients are, in particular, fillers such as sugars, including lactose, sucrose, mannitol or sorbitol; cellulose preparations such as, for example, corn starch, wheat starch, rice starch, potato starch, gelatin, tragacanth gum, methyl cellulose, hydrocylpropylmethyl cellulose, sodium carboxymethylcellulose and / or polyvinylpyrrolidone (PVP). If desired, disintegrating agents may be added, such as cross-linking polyvinylpyrrolidone, agar or alginic acid or a salt thereof such as sodium alginate. Dragee centers are provided with adequate coatings. For this purpose, concentrated sugar solutions can be used, which optionally contain gum arabic, talcum, polyvinylpyrrolidone, carbopol gel, polyethylene glycol and / or titanium dioxide, lacquer solutions and suitable organic solvents or solvent mixtures. The dyes or pigments can be coated onto the tablets or coated with dragees for identification or to characterize different combinations of doses of active compounds. Pharmaceutical preparations that can be used orally include push capsules made of gelatin as well as softly sealed capsules made of cgelatine and a plasticizer such as glycerol or sorbitol. The push capsules may contain the active ingredients in a mixture with filler such as lactose, binders such as starches and / or lubricants such as talc or magnesium stearate and optionally, stabilizers. In soft capsules, 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 oral administration formulations may be in doses suitable for administration. For buccal administration, the compositions may take the form of tablets or diamonds formulated in a conventional manner. For administration by inhalation, the compounds to be used according to the present invention are conveniently delivered in the form of an aerosol spray presentation of pressurized packets or a nebulizer, with the use of a suitable propellant, for example, dichlorodifluoromethane, trichlorofluoromethane, dichlorotetrafluoroethane , carbon dioxide or other suitable gas, or free of propellant, dry powder inhalers. In the case of a pressurized aerosol, the dosage unit can be determined by providing a valve for the release of a measured quantity. Capsules and cartridges of, for example, gelatin for use in an inhaler or insufflator can be formulated by containing a mixture of powder and a suitable powder base such as lactose or starch. The compounds can be formulated for parenteral administration by injection, for example, by means of an injection bolus or continuous infusion. Formulations by injection may be presented as a dosage unit, for example, in ampules or in multi-dose containers, with an additional preservative. The compositions may take the form of suspensions, solutions or emulsions in oily or aqueous vehicles and may contain formulating agents such as suspending, stabilizing and / or dispersing agents. Pharmaceutical formulations for parenteral administration include aqueous solutions of the active compounds in water soluble forms. Additionally, suspensions of the active compounds can be prepared as oily injectable suspensions. Suitable lipophilic solvents or carriers include fatty oils such as sesame oil, or synthetic fatty acid esters such as ethyl oleate or triglycerides or liposomes. Aqueous injectable suspensions may contain substances that increase the viscosity of the suspension such as sodium carboxymethylcellulose, sorbitol or dextran. Optionally, the suspension may also contain stabilizers or suitable agents that increase the solubility of the compounds to allow the preparation of highly concentrated solutions. Alternatively, the active ingredient may be in powder form for constitution with a suitable vehicle, eg, sterile, pyrogen-free water, before use. The compounds can also be formulated in rectal compositions, suppositories or retention enemas, for example, containing conventional suppository bases such as cocoa butter, carboceras, polyethylene glycols or other gylcerides, all with a melting point at body temperature, but which solidify at room temperature. In addition to the formulations described previously, the compounds can also be formulated as a depot preparation. Formulations that act for prolonged periods can be administered by implantation (for example, as an emulsion in an acceptable oil) or by ion exchange resins or as economical soluble derivatives, for example, a soluble and economical salt. Alternatively, other delivery systems of the pharmaceutically hydrophobic compounds can be used. Liposomes and emulsions are well known examples of delivery vehicles or carriers for hydrophobic drugs. In a currently preferred embodiment, large circulants, i.e., discrete liposomes, may be employed. Liposomes are described generally in Woodle et al. , U.S. Patent No. 5,013,556. The compounds of the present invention may also be administered by controlled release means and / or delivery devices such as those described in US 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) can also be used, although usually the cost is a great toxicity. Additionally, the compounds can be released using a sustained release system, such as semipermeable matrices of solid idrophobic polymers containing the therapeutic agent. Various types of sustained release materials have been established and are well known to the person skilled in the art. Sustained-release capsules can, depending on their chemical nature, release the compounds for a few hours up to 100 days. The pharmaceutical compositions may further comprise suitable solid phase or gel carriers or excipients. Examples of these carriers or excipients include but are not limited to calcium carbonate, 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, according to the weight of the subject, the severity of the affliction, the form of administration and the judgment of the prescribing physician. The determination of an effective amount is well within the ability of the person skilled in the art, especially by virtue of the detailed description provided herein. For any compound used in the method of the present invention, a therapeutically effective dose can be estimated initially from the analysis of cell cultures or animal models. Moreover, the toxicity and therapeutic efficacy of the compounds described herein can be determined by conventional pharmaceutical procedures in cell cultures or experimental animals, for example, by determining the LD50 (the lethal dose of 50% of the population) and the ED50 (the dose therapeutically effective in 50% of the population). The dose ratio between the therapeutic effect and the toxic effect is the therapeutic index that can be expressed as the ratio between LD50 and ED50. Compounds that show high therapeutic indices are preferred. The data obtained from these cell culture assays and animal studies can be used in formulating a dose ratio that is non-toxic for human use. The dosage of these compounds is preferably supported within a range of circulating concentrations that include the ED50 with little or no toxicity. The dosage may vary within this proportion depending on the dosage form employed and the route of administration used. The exact formulation, route of administration and dosage can be individually selected by the physician in view of the patient's condition. (See, for example, Fingí et al., 1975 In: The Pharmacological Basis of Therapeutics, Chapter 1). The amount of active compound that can be combined with the carrier material to produce a simple dosage form can vary depending on the disease being treated, the species of mammal and the particular form of administration. However, as a general guide, suitable dosage units 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 dosage unit is between 500 mg to about 1500 mg. A more preferred dosage unit is between 500 to about 1000 mg. These dosage units 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, such that the daily dosage for an adult of 70 kg is in the proportion of 0.1 to about 250 mg per kg of subject weight per administration. A preferred dosage is from 5 to about 250 mg per kg of subject weight per administration and this therapy may be extended for a number of weeks or months and in some cases, years. It will be understood, however, that the specific dosage 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 to be treated; the time and route of administration, the rate of excretion; other drugs that have been previously administered; and the severity of the particular disease submitted to therapy, will be well understood by those experts in the area.
A typical dosage may be a tablet of 10 to about 1500 mg taken once a day or multiple times a day, or a time-release capsule taken once a day containing a highly proportional content of the active ingredient. The effect of release time can be obtained by capsule materials that dissolve at different pH values, by capsules that are released slowly by osmotic pressure, or by other known means of controlled release. It may be necessary to use dosages outside these proportions which in some cases will be apparent to the person skilled in the art. In addition, it will be noted that the clinician or attending physician will know how and when to interrupt, adjust or terminate the therapy in conjunction with the patient's individual response.
Combination Therapy As noted above, the compounds of the present invention may in some instances be used in combination with other therapeutic agents to achieve the desired effect. The selection of additional agents will be largely dependent on the desired target therapy (see, for example, Turner N. et al. Prog. Drug Res. (198) 51: 33-94; Haffner, S. Diabetes Care (1998) 21: 160-178; and DeFronzo, R. Et al. (Editors), Diabetes Reviews (1997) Vol. 5 No. 4).
A number of studies have investigated the benefits of combination therapies with oral agents (see for example, Mahler, R., J. Clin, Endocrinol, Metab. (1999) 84: 1165-71, Prospective Study Group of Diabetes. from the United Kingdom: UKPDS 28, Diabetes Care (1998) 21: 87-92; Bardin, CW, (editor), CURRENT THERAPY IN ENDOCRINOLOGY AND METABOL1SM, 6th edition (Mosby - Year Book, Inc., St. Louis, MO 1997); Chiasson J. et al., Ann. Intern. Med. (1994) 121: 928-935; Coniff, R. Et al., Clin. Ther. (1997) 19: 16-26; Coniff, R. Et al. ., Am. J. Med. (1995) 98: 443-451 and Iwamoto, Y. Et al., Diabet. Med. (1996) 13: 365-370; Keroerovich, P. Am. J. Cardiol. 1998) 82 (12A): 3U-17U). These studies indicate that the regulation of diabetes and hyperlipidemia can also be improved by the addition of a second agent to the therapeutic regimen. The combination therapy includes the administration of a simple pharmaceutical dosage containing a compound having the general structure of formula 1 and one or more additional active agents as well as the administration of a compound of formula 1 and each active agent in this formulation own of separate pharmaceutical dosage. For example, a compound of formula 1 and a HMG-CoA reductase inhibitor can be administered to the human subject together with a simple oral dosage composition, such as a tablet or capsule, or caga agent can be administered separately in oral dosage formulations. While the dosage formulations are used separately, a compound of formula 1 and one or more additional active agents can be administered at essentially the same time (ie, concurrently), or at staggered times separately (ie, sequentially) . The combination therapy is understood to include all of these regimens. An example of a combination therapy that regulates atherosclerosis (prevents attack of symptoms or associated complications), wherein a compound of formula 1 is administered in combination with one or more of the active compounds: an antihyperlipidemic agent; an agent that increases HDL in plasma; an antihypercholesterolemic agent, such as the cholesterol biosynthesis inhibitor, for example, a hydroxymethylglutaryl (HMG) CoA reductase inhibitor (also referred to as statins, such as loastatin, sinvastatin, pravastatin, fluvastatin and atrovastatin), an HMG-CoA synthase inhibitor, an squalene epoxidase inhibitor, or a squalene synthetase inhibitor (also known as an squalene synthase inhibitor); an inhibitor acyl-coenzyme A cholesterol acyltransferase (ACAT), such as melinamide; probucol; nicotinic acid and the salts of these and niacinamide; a cholesterol absorption inhibitor, such as β-sitosterol; an anionic exchange resin bile acid sequester, such as cholestyramine, colestipol or dialkylaminoalkyl derivatives of a cross-linking dextran; an inducer of LDL (low density lipoprotein); fibrates such as clofibrate, bezafibrate, fenofibrate and genfibrizol; vitamin Be (also known as pyridoxine) and pharmaceutically acceptable salts thereof, such as the HCl salt; vitamin Bi2 (also known as cyanocobalamin); vitamin B3 (also known as nicotinic acid and niacinamide, supra); antioxidant vitamins such as vitamins C and E and beta carotenes; a beta-blocker; an angiotensin II antagonist; an enzyme inhibitor that converts angiontensin; and a platelet aggregation inhibitor such as fibrinogen receptor antagonists (i.e., glycoprotein receptor IIb / fibrinogen Illa antagonists) and aspirin. As noted above, the compounds of formula 1 can be administered in combination with more than one additional active agent, for example, a combination of a compound of formula 1 with an HMG-CoA reductase inhibitor (for example, lovastatin, sinvastatin and prevastatin) and aspirin, or a compound of formula 1 with an HMG-CoA reductase inhibitor and a β-blocker. Another example of combination therapy can be seen in the treatment of obesity or in disorders related to obesity, where the compounds of formula 1 can be used effectively in combination with for example, phenylpropanolamine, phentermine, diethylpropion, mazindol; fenfluramine, dexfenfluramine, fentiramine, β3-adrenoceptor agonists; sibutramine, gastrointestinal lipase inhibitors (such as orlistat) and leptins.

Even another example of combination therapy can be seen in the regulation of diabetes (or treating diabetes and its related symptoms, complications and disorders), where the compounds of formula 1 can be used effectively in combination with for example, sulfonylureas (such as chlorpropamide) , tolbutamide, acetohexamide, tolazamide, glyburide, glyzazoda, glinease, glimepiride and glipizide), biguanides (such as metformin), thiazolidinediones (such as ciglitazone, pioglitazone, troglitazone and rosiglitazone); dehydroepiandrosterone (also referred to as DHEA or its conjugated sulfate ester, DHEA-S04); antiglucocorticoids; TNFa inhibitors; a-glucosidase inhibitors (such as acarbose, miglitol and voglibose), pramlintide (a synthetic analogue of the human hormone amylin), other insulin secregogues (such as repaglinide, gliquidone and nateglinide), insulin, as well as the active agents discussed above for the treatment of atherosclerosis. A further example of combination therapy may be in the regulation of hyperlipidemia (treatment of hyperlipidemia and its related complications), wherein the compounds of formula 1 can be effectively used in combination with for example, statins (such as fluvastatin, lovastatin, pravastatin or sinvastatin), resins that bind to bile acid (such as colestipol or cholestyramine), nicotinic acid, probicol, beta-carotene, vitamin E or vitamin C. Additionally, an effective amount of a compound of formula 1 and a therapeutically effective of one or more active agents selected from the group consisting of: an antihyperlipidemic agent; an agent that increases HDL in plasma; an anti-hypercholesterolemic agent, such as a cholesterol biosynthesis inhibitor, for example, a HMG-CoA reductase inhibitor, an HMG-CoA synthase inhibitor, a squalene epoxidase inhibitor, or a squalene synthase inhibitor (also known as an squalene synthase inhibitor); an acyl-coenzyme A cholesterol acyltransferase inhibitor; probucol; nicotinic acid and salts thereof; niacinamide; a cholesterol absorption inhibitor; an anion exchange resin bile acid sequestrant; a low density lipoprotein receptor inducer; clofibrate; fenofibrate and genfibrozil; vitamin B6 and pharmaceutically acceptable salts thereof; vitamin B? 2; an antioxidant vitamin; a β-blocker; an angiotensin II antagonist; an angiotensin-converting enzyme inhibitor; an inhibitor of platelet aggregation; a fibrinogen receptor antagonist; aspirin; Fentiramines; ß3 adrenergic receptor agonists; sulfonylureas, biguanides, a-glucosidase inhibitors, other insulin secretes and insulin can be used together for the preparation of a pharmaceutical composition useful for the treatments described above.

In addition to the containers that contain the unit doses, there is an information package insert that describes the use and benefits of functioning of the drugs in the improvement of symptoms and / or complications associated with Type 2 diabetes, as well as in the improvement of hyperlipidemia and hyperuricemia, or to improve PPAR-dependent conditions.
