Description

N-HETEROARYL INDOLE CARBOXAMIDES AND ANALOGUES THEREOF, FOR USE AS GLUCOKINASE ACTIVATORS IN THE TREATMENT OF DIABETES

FIELD OF THE INVENTION

This invention relates to compounds that are activators of glucokinase and thus may be useful for the management, treatment, control, or adjunct treatment of diseases, where increas- ing glucokinase activity is beneficial.

BACKGROUND OF THE INVENTION Diabetes is characterised by an impaired glucose metabolism manifesting itself among other things by an elevated blood glucose level in the diabetic patients. Underlying defects lead to a classification of diabetes into two major groups: Type 1 diabetes, or insulin demanding diabetes mellitus (IDDM), which arises when patients lack ?-cells producing insulin in their pancreatic glands, and type 2 diabetes, or non-insulin dependent diabetes mellitus (NIDDM), which occurs in patients with an impaired β-ce\\ function besides a range of other abnormalities. Type 1 diabetic patients are currently treated with insulin, while the majority of type 2 diabetic patients are treated either with sulphonylureas that stimulate jff-cell function or with agents that enhance the tissue sensitivity of the patients towards insulin or with insulin. Among the agents applied to enhance tissue sensitivity towards insulin metformin is a representative example. Even though sulphonylureas are widely used in the treatment of NIDDM this therapy is, in most instances, not satisfactory: In a large number of NIDDM patients sulphonylureas do not suffice to normalise blood sugar levels and the patients are, therefore, at high risk for acquiring diabetic complications. Also, many patients gradually lose the ability to respond to treatment with sulphonylureas and are thus gradually forced into insulin treatment. This shift of patients from oral hypoglycaemic agents to insulin therapy is usually ascribed to exhaus- tion of the yff-cells in NIDDM patients. In normal subjects as well as in diabetic subjects, the liver produces glucose in order to avoid hypoglycaemia. This glucose production is derived either from the release of glucose from glycogen stores or from gluconeogenesis, which is a de novo intracellular synthesis of glucose. In type 2 diabetes, however, the regulation of hepatic glucose output is poorly controlled and is increased, and may be doubled after an overnight fast. Moreover, in these patients there exists a strong correlation between the increased fasting plasma glucose levels and the rate of hepatic glucose production. Similarly, hepatic glucose production will be increased in type 1 diabetes, if the disease is not properly controlled by insulin treatment. Since existing forms of therapy of diabetes does not lead to sufficient glycaemic control and therefore are unsatisfactory, there is a great demand for novel therapeutic approaches. Atherosclerosis, a disease of the arteries, is recognized to be the leading cause of death in the United States and Western Europe. The pathological sequence leading to atherosclerosis and occlusive heart disease is well known. The earliest stage in this sequence is the formation of "fatty streaks" in the carotid, coronary and cerebral arteries and in the aorta. These lesions are yellow in colour due to the presence of lipid deposits found principally within smooth-muscle cells and in macrophages of the intima layer of the arteries and aorta. Further, it is postulated that most of the cholesterol found within the fatty streaks, in turn, give rise to development of the "fibrous plaque", which consists of accumulated intimal smooth muscle cells laden with lipid and surrounded by extra-cellular lipid, collagen, elastin and proteoglycans. The cells plus matrix form a fibrous cap that covers a deeper deposit of cell debris and more extracellular lipid. The lipid is primarily free and esterified cholesterol. The fibrous plaque forms slowly, and is likely in time to become calcified and necrotic, advancing to the "complicated lesion" which accounts for the arterial occlusion and tendency toward mural thrombosis and arterial muscle spasm that characterize advanced atherosclerosis. Epidemiological evidence has firmly established hyperlipidemia as a primary risk factor in causing cardiovascular disease (CVD) due to atherosclerosis. In recent years, leaders of the medical profession have placed renewed emphasis on lowering plasma cholesterol levels, and low density lipoprotein cholesterol in particular, as an essential step in prevention of CVD. The upper limits of "normal" are now known to be significantly lower than heretofore appreciated. As a result, large segments of Western populations are now realized to be at particular high risk. Independent risk factors include glucose intolerance, left ventricular hypertrophy, hypertension, and being of the male sex. Cardiovascular disease is especially prevalent among diabetic subjects, at least in part because of the existence of multiple independent risk factors in this population. Successful treatment of hyperlipidemia in the general population, and in diabetic subjects in particular, is therefore of exceptional medical impor- tance. Hypertension (or high blood pressure) is a condition, which occurs in the human population as a secondary symptom to various other disorders such as renal artery stenosis, pheochromocytoma, or endocrine disorders. However, hypertension is also evidenced in many patients in whom the causative agent or disorder is unknown. While such "essential" hypertension is often associated with disorders such as obesity, diabetes, and hypertriglyc- eridemia, the relationship between these disorders has not been elucidated. Additionally, many patients display the symptoms of high blood pressure in the complete absence of any other signs of disease or disorder. It is known that hypertension can directly lead to heart failure, renal failure, and stroke (brain haemorrhaging). These conditions are capable of causing short-term death in a patient. Hypertension can also contribute to the development of atherosclerosis and coronary disease. These conditions gradually weaken a patient and can lead to long-term death. The exact cause of essential hypertension is unknown, though a number of factors are believed to contribute to the onset of the disease. Among such factors are stress, uncon- trolled emotions, unregulated hormone release (the renin, angiotensin aldosterone system), excessive salt and water due to kidney malfunction, wall thickening and hypertrophy of the vasculature resulting in constricted blood vessels and genetic factors. The treatment of essential hypertension has been undertaken bearing the foregoing factors in mind. Thus a broad range of beta-blockers, vasoconstrictors, angiotensin convert- ing enzyme inhibitors and the like have been developed and marketed as antihypertensives. The treatment of hypertension utilizing these compounds has proven beneficial in the prevention of short-interval deaths such as heart failure, renal failure, and brain haemorrhaging. However, the development of atherosclerosis or heart disease due to hypertension over a long period of time remains a problem. This implies that although high blood pressure is be- ing reduced, the underlying cause of essential hypertension is not responding to this treatment. Hypertension has been associated with elevated blood insulin levels, a condition known as hyperinsulinemia. Insulin, a peptide hormone whose primary actions are to promote glucose utilization, protein synthesis and the formation and storage of neutral lipids, also acts to promote vascular cell growth and increase renal sodium retention, among other things. These latter functions can be accomplished without affecting glucose levels and are known causes of hypertension. Peripheral vasculature growth, for example, can cause constriction of peripheral capillaries, while sodium retention increases blood volume. Thus, the lowering of insulin levels in hyperinsulinemics can prevent abnormal vascular growth and re- nal sodium retention caused by high insulin levels and thereby alleviates hypertension. Cardiac hypertrophy is a significant risk factor in the development of sudden death, myocardial infarction, and congestive heart failure. Theses cardiac events are due, at least in part, to increased susceptibility to myocardial injury after ischemia and reperfusion, which can occur in out-patient as well as perioperative settings. There is an unmet medical need to prevent or minimize adverse myocardial perioperative outcomes, particularly perioperative myocardial infarction. Both non-cardiac and cardiac surgery are associated with substantial risks for myocardial infarction or death. Some 7 million patients undergoing non-cardiac surgery are considered to be at risk, with incidences of perioperative death and serious cardiac complications as high as 20-25% in some series. In addition, of the 400,000 patients under- going coronary by-pass surgery annually, perioperative myocardial infarction is estimated to occur in 5% and death in 1-2%. There is currently no drug therapy in this area, which reduces damage to cardiac tissue from perioperative myocardial ischemia or enhances cardiac resistance to ischemic episodes. Such a therapy is anticipated to be life-saving and reduce hospitalizations, enhance quality of life and reduce overall health care costs of high risk pa- tients. Obesity is a well-known risk factor for the development of many very common diseases such as atherosclerosis, hypertension, and diabetes. The incidence of obese people and thereby also these diseases is increasing throughout the entire industrialised world. Except for exercise, diet and food restriction no convincing pharmacological treatment for re- ducing body weight effectively and acceptably currently exists. However, due to its indirect but important effect as a risk factor in mortal and common diseases it will be important to find treatment for obesity and/or means of appetite regulation. The term obesity implies an excess of adipose tissue. In this context obesity is best viewed as any degree of excess adiposity that imparts a health risk. The cut off between normal and obese individuals can only be approximated, but the health risk imparted by the obesity is probably a continuum with increasing adiposity. The Framingham study demonstrated that a 20% excess over desirable weight clearly imparted a health risk (Mann GV N.Engl.J.Med 291 :226, 1974). In the United States a National Institutes of Health consensus panel on obesity agreed that a 20% increase in relative weight or a body mass index (BMI = body weight in kilograms divided by the square of the height in meters) above the 85th per- centile for young adults constitutes a health risk. By the use of these criteria 20 to 30 percent of adult men and 30 to 40 percent of adult women in the United States are obese. (NIH, Ann Intern Med 103:147, 1985). Even mild obesity increases the risk for premature death, diabetes, hypertension, atherosclerosis, gallbladder disease, and certain types of cancer. In the industrialised western world the prevalence of obesity has increased significantly in the past few decades. Because of the high prevalence of obesity and its health consequences, its prevention and treatment should be a high public health priority. When energy intake exceeds expenditure, the excess calories are stored in adipose tissue, and if this net positive balance is prolonged, obesity results, i.e. there are two compo- nents to weight balance, and an abnormality on either side (intake or expenditure) can lead to obesity. The regulation of eating behaviour is incompletely understood. To some extent appetite is controlled by discrete areas in the hypothalamus: a feeding centre in the ventro- lateral nucleus of the hypothalamus (VLH) and a satiety centre in the ventromedial hypothalamus (VMH). The cerebral cortex receives positive signals from the feeding centre that stimulate eating, and the satiety centre modulates this process by sending inhibitory impulses to the feeding centre. Several regulatory processes may influence these hypothalamic centres. The satiety centre may be activated by the increases in plasma glucose and/or insu- lin that follow a meal. Meal-induced gastric distension is another possible inhibitory factor. Additionally the hypothalamic centres are sensitive to catecholamines, and beta-adrenergic stimulation inhibits eating behaviour. Ultimately, the cerebral cortex controls eating behaviour, and impulses from the feeding centre to the cerebral cortex are only one input. Psychological, social, and genetic factors also influence food intake. At present a variety of techniques are available to effect initial weight loss. Unfortunately, initial weight loss is not an optimal therapeutic goal. Rather, the problem is that most obese patients eventually regain their weight. An effective means to establish and/or sustain weight loss is the major challenge in the treatment of obesity today.

DESCRIPTION OF THE INVENTION Glucokinase (GK) plays an essential role in blood glucose homeostasis. GK catalyses glucose phosphorylation, and is the rate-limiting reaction for glycolysis in hepatocytes and pancreatic β-cells. In liver GK determine the rates of both glucose uptake and glycogen synthesis, and it is also thought to be essential for the regulation of various glucose- responsive genes (Girard, J.et al., Annu Rev Nutr 17, 325-352 (1997)). In the /ff-cells, GK determines glucose utilization and thus is necessary for glucose-stimulated insulin secretion. GK is also expressed in a population of neurones in the hypothalamus where it might be involved in feeding behaviour, and in the gut where it might contribute to the secretion of en- teroincretins. GK has two main distinctive characteristics: its expression, which is limited to tissues that require glucose-sensing (mainly liver and pancreatic ?-cells), and its S_0.sfor glu- cose, which is much higher (8-12 mM) than that of the other members of the hexokinase family. Due to these kinetic characteristics, changes in serum glucose levels are paralleled by changes in glucose metabolism in liver which in turn regulate the balance between hepatic glucose output and glucose consumption. Activators of glucokinase may thus be useful for treating diseases where increasing the activity of glucokinase is beneficial. Thus, there is a need for agents which activate glucokinase and increase glucokinase enzymatic activity. Such agents would be useful for the treatment of type I diabetes and type II diabetes. Activators of glucokinase may also play a role in sensing low glucose levels and generating neurohumoral responses to hypoglycemia and may thus be useful for treating those patients with type 1 diabetes, which have a higher tendency to suffer from hypoglycemia. Type I diabetes mellitus is a complex disease characterized by an elevated blood glucose concentration and polyuria. Secondary to the persistent elevation in blood glucose, patients develop devastating complications such as retinopathy, nephropathy, neuropathy, and cardiovascular disease. A major goal to improve the diabetic phenotype is to reduce fasting and postprandial hyperglycemia and, thus, avoid or delay the onset of diabetic complications. The Diabetes Control and Complications Trial has indicated that tight glycemic control through administration of daily multiple insulin injections delays the onset of complications. However, such intensive therapy is associated with an increase in body weight and higher risk for development of hypoglycaemic events. Alternative treatments to achieve glucose control without these side effects are, therefore, being developed. The combination of GK overexpression in the liver and subcutaneous insulin injections provides better glycemic control in type 1 diabetic animals than treatment with insulin alone (Morral, N., et al. Human Gene Therapy 13, 1561-1570 (2002)). Moreover, overexpression of hepatic GK can com- pensate, in part, for the metabolic disorders developed by insulin receptor-deficient mice (Jackerott, M. et al. Diabetologia 45, 1292-1297 (2002)). The present invention also relates to the use of a GK activator for the combined treatment of diabetes and obesity. GK, the GK regulatory protein and the KATP channel are expressed in neurones of the hypothalamus, a region of the brain that is important in the regulation of energy balance and the control of food intake. These neurones have been shown to express orectic and anorectic neuropeptides and have been assumed to be the glucose-sensing neurones within the hypothalamus that are either inhibited or excited by changes in ambient glucose concentrations (Mobbs, C. V. et al, American Journal of Physi- ology, Endocrinology & Metabolism 281., E649-54 (2001 )). The ability of these neurones to sense changes in glucose levels is defective in a variety of genetic and experimentally induced models of obesity (Spanswick, D. et al, Nature Neuroscience 3, 757-8 (2000), Levin, B. E. et al, Brain Research 808, 317-9 (1998)). Intracerebroventricular (icv) infusion of glucose analogues, which are competitive inhibitors of glucokinase, stimulate food intake in lean rats (Kurata, K. et al, Metabolism: Clinical & Experimental 38, 46-51 (1989)). In contrast, icv infusion of glucose suppresses feeding (Kurata, K.et al, Physiology & Behavior 37, 615-20 (1986)). Small molecule activators of GK may thus decrease food intake and weight gain through central effects on GK. Therefore, GK activators may be of therapeutic use in treating eating disorders, including obesity, in addition to diabetes. The hypothalamic effects will be additive or synergistic to the effects of the same compounds acting in the liver and/or pancreas in normalising glucose homeostasis, for the treatment of type 2 diabetes. Thus the GK/GK regulatory protein system can be described as a potential target of benefit in both diabetes and obesity. The amplitude of glucose-induce insulin release is highly dependent on the action of the gastrointestinal hormones GLP-1 (glucogen-like peptide 1) and GIP. Unlike sulfony- lureas, which stimulate insulin release at low as well as high glucose levels, the action of GLP-1 on ff-cells is glucose dependent (Gromada, J. et al., Pflϋgers Arch 435, 583-594 (1998)). GLP-1 receptor agonist and drugs that slow the degradation of active GLP-1 are therefore under development as a novel treatments for type 2 diabetes. An alternative strat- egy would be to enhance endogenous GLP-1 levels. Of potential interest is the possibility that the release of GLP-1 and GIP might be regulated by glucokinase-expressing endocrine cells (Jetton, T.L et al., J. Biol. Chem. 269, 3641-3654 (1994)) and glucose-responsive neurons (Liu, M. et al., J. Neurosci. 19, 10305-10317 (1999)). It has been reported that the release of GIP by intestinal K-cells is directly controlled by glucose (Kieffer, T.J. et al., Am J Physiol 267, E489-E496 (1994)), and GLP-1 secretion from GLUTag cells is triggered by glucose through a mechanism similar to that found in ?-cells for insulin secretion (Reimann, F. et al, Diabetes 5_1, 2757-2763 (2002)). Small molecule activators of glucokinase may thus be used to increase GLP-1 and /or GIP secretion and thus for treatment, modulation, inhibition, decreasion, reduction, arrest or prevention of beta cell degeneration, such as necrosis or apoptosis of 0-cells. The invention is further exemplified by the following embodiments:

In another embodiment the GLP-1 derivative to be employed in combination with a compound of the present invention refers to GLP-1(1-37), exendin-4(1-39), insulinotropic fragments thereof, insulinotropic analogues thereof and insulinotropic derivatives thereof. Insulinotropic fragments of GLP-1 (1-37) are insulinotropic peptides for which the entire sequence can be found in the sequence of GLP-1 (1-37) and where at least one terminal amino acid has been deleted. Examples of insulinotropic fragments of GLP-1 (1-37) are GLP-1 (7-37) wherein the amino acid residues in positions 1-6 of GLP-1 (1-37) have been deleted, and GLP-1 (7-36) where the amino acid residues in position 1-6 and 37 of GLP-1 (1-37) have been deleted. Examples of insulinotropic fragments of exendin-4(1-39) are exendin-4(1-38) and exendin-4(1-31). The insulinotropic property of a compound may be determined by in vivo or in vitro assays well known in the art. For instance, the compound may be administered to an animal and monitoring the insulin concentration over time. Insulinotropic analogues of GLP- 1 (1-37) and exendin-4(1 -39) refer to the respective molecules wherein one or more of the amino acids residues have been exchanged with other amino acid residues and/or from which one or more amino acid residues have been deleted and/or from which one or more amino acid residues have been added with the proviso that said analogue either is insulinotropic or is a prodrug of an insulinotropic compound . Examples of insulinotropic analogues of GLP-1 (1-37) are e.g. Met⁸-GLP-1(7-37) wherein the alanine in position 8 has been replaced by methionine and the amino acid residues in position 1 to 6 have been deleted, and Arg³⁴- GLP-1(7-37) wherein the valine in position 34 has been replaced with arginine and the amino acid residues in position 1 to 6 have been deleted. An example of an insulinotropic analogue of exendin-4(1-39) is Ser²Asp³-exendin-4(1-39) wherein the amino acid residues in position 2 and 3 have been replaced with serine and aspartic acid, respectively (this particular analogue also being known in the art as exendin-3). Insulinotropic derivatives of GLP-1 (1- 37), exendin-4(1-39) and analogues thereof are what the person skilled in the art considers to be derivatives of these peptides, i.e. having at least one substituent which is not present in the parent peptide molecule with the proviso that said derivative either is insulinotropic or is a prodrug of an insulinotropic compound. Examples of substituents are amides, carbohydrates, alkyl groups and lipophilic substituents. Examples of insulinotropic derivatives of GLP-1 (1- 37), exendin-4(1-39) and analogues thereof are GLP-1 (7-36)-amide, Arg³⁴, Lys²⁶(N^ε-(γ- Glu(N -hexadecanoyl)))-GLP-1(7-37) and Tyr^-exendin^l-Sl^amide.

PHARMACEUTICAL COMPOSITIONS

The compounds of the present invention may be administered alone or in combination with pharmaceutically acceptable carriers or excipients, in either single or multiple doses. The pharmaceutical compositions according to the invention may be formulated with pharmaceutically acceptable carriers or diluents as well as any other known adjuvants and ex- cipients in accordance with conventional techniques such as those disclosed in Remington: The Science and Practice of Pharmacy, 19^th Edition, Gennaro, Ed., Mack Publishing Co., Easton, PA, 1995. The pharmaceutical compositions may be specifically formulated for administration by any suitable route such as the oral, rectal, nasal, pulmonary, topical (including buccal and sublingual), transdermal, intracisternal, intraperitoneal, vaginal and parenteral (including subcutaneous, intramuscular, intrathecal, intravenous and intradermal) route, the oral route being preferred. It will be appreciated that the preferred route will depend on the general condition and age of the subject to be treated, the nature of the condition to be treated and the ac- tive ingredient chosen. Pharmaceutical compositions for oral administration include solid dosage forms such as hard or soft capsules, tablets, troches, dragees, pills, lozenges, powders and granules. Where appropriate, they can be prepared with coatings such as enteric coatings or they can be formulated so as to provide controlled release of the active ingredient such as sus- tained or prolonged release according to methods well known in the art. Liquid dosage forms for oral administration include solutions, emulsions, aqueous or oily suspensions, syrups and elixirs. Pharmaceutical compositions for parenteral administration include sterile aqueous and non-aqueous injectable solutions, dispersions, suspensions or emulsions as well as ster- ile powders to be reconstituted in sterile injectable solutions or dispersions prior to use. Depot injectable formulations are also contemplated as being within the scope of the present invention. Other suitable administration forms include suppositories, sprays, ointments, cremes, gels, inhalants, dermal patches, implants etc. A typical oral dosage is in the range of from about 0.001 to about 100 mg/kg body weight per day, preferably from about 0.01 to about 50 mg/kg body weight per day, and more preferred from about 0.05 to about 10 mg/kg body weight per day administered in one or more dosages such as 1 to 3 dosages. The exact dosage will depend upon the frequency and mode of administration, the sex, age, weight and general condition of the subject treated, the nature and severity of the condition treated and any concomitant diseases to be treated and other factors evident to those skilled in the art. The formulations may conveniently be presented in unit dosage form by methods known to those skilled in the art. A typical unit dosage form for oral administration one or more times per day such as 1 to 3 times per day may contain from 0.05 to about 1000 mg, preferably from about 0.1 to about 500 mg, and more preferred from about 0.5 mg to about 200 mg. For parenteral routes such as intravenous, intrathecal, intramuscular and similar administration, typically doses are in the order of about half the dose employed for oral administration. The compounds of this invention are generally utilized as the free substance or as a pharmaceutically acceptable salt thereof. Examples are an acid addition salt of a compound having the utility of a free base and a base addition salt of a compound having the utility of a free acid. The term "pharmaceutically acceptable salts" refers to non-toxic salts of the com- pounds of this invention which are generally prepared by reacting the free base with a suitable organic or inorganic acid or by reacting the acid with a suitable organic or inorganic base. When a compound according to the present invention contains a free base such salts are prepared in a conventional manner by treating a solution or suspension of the compound with a chemical equivalent of a pharmaceutically acceptable acid. When a compound accord- ing to the present invention contains a free acid such salts are prepared in a conventional manner by treating a solution or suspension of the compound with a chemical equivalent of a pharmaceutically acceptable base. Physiologically acceptable salts of a compound with a hydroxy group include the anion of said compound in combination with a suitable cation such as sodium or ammonium ion. Other salts which are not pharmaceutically acceptable may be useful in the preparation of compounds of the present invention and these form a further aspect of the present invention. For parenteral administration, solutions of the novel compounds of the above formulae in sterile aqueous solution, aqueous propylene glycol or sesame or peanut oil may be employed. Such aqueous solutions should be suitably buffered if necessary and the liquid diluent first rendered isotonic with sufficient saline or glucose. The aqueous solutions are particularly suitable for intravenous, intramuscular, subcutaneous and intraperitoneal administration. The sterile aqueous media employed are all readily available by standard techniques known to those skilled in the art. Suitable pharmaceutical carriers include inert solid diluents or fillers, sterile aqueous solution and various organic solvents. Examples of solid carriers are lactose, terra alba, sucrose, cyclodextrin, talc, gelatine, agar, pectin, acacia, magnesium stearate, stearic acid and lower alkyl ethers of cellulose. Examples of liquid carriers are syrup, peanut oil, olive oil, phospholipids, fatty acids, fatty acid amines, polyoxyethylene and water. Similarly, the carrier or diluent may include any sustained release material known in the art, such as glyceryl monostearate or glyceryl distearate, alone or mixed with a wax. The pharmaceutical compositions formed by combining the novel compounds of the present invention and the pharmaceutically acceptable carriers are then readily administered in a variety of dosage forms suitable for the disclosed routes of administration. The formulations may conveniently be presented in unit dosage form by methods known in the art of pharmacy. Formulations of the present invention suitable for oral administration may be presented as discrete units such as capsules or tablets, each containing a predetermined amount of the active ingredient, and which may include a suitable excipient. Furthermore, the orally available formulations may be in the form of a powder or granules, a solution or sus- pension in an aqueous or non-aqueous liquid, or an oil-in-water or water-in-oil liquid emulsion. Compositions intended for oral use may be prepared according to any known method, and such compositions may contain one or more agents selected from the group consisting of sweetening agents, flavoring agents, coloring agents, and preserving agents in order to provide pharmaceutically elegant and palatable preparations. Tablets may contain the active ingredient in admixture with non-toxic pharmaceutically-acceptable excipients which are suitable for the manufacture of tablets. These excipients may be for example, inert diluents, such as calcium carbonate, sodium carbonate, lactose, calcium phosphate or sodium phosphate; granulating and disintegrating agents, for example corn starch or alginic acid; binding agents, for example, starch, gelatin or acacia; and lubricating agents, for example magnesium stearate, stearic acid or talc. The tablets may be uncoated or they may be coated by known techniques to delay disintegration and absorption in the gastrointestinal tract and thereby provide a sustained action over a longer period. For example, a time delay material such as glyceryl monostearate or glyceryl distearate may be employed. They may also be coated by the techniques described in U.S. Patent Nos. 4,356,108; 4,166,452; and 4,265,874, incorporated herein by reference, to form osmotic therapeutic tablets for controlled release. Formulations for oral use may also be presented as hard gelatin capsules where the active ingredient is mixed with an inert solid diluent, for example, calcium carbonate, calcium phosphate or kaolin, or a soft gelatin capsules wherein the active ingredient is mixed with water or an oil medium, for example peanut oil, liquid paraffin, or olive oil. Aqueous suspensions may contain the active compounds in admixture with excipients suitable for the manufacture of aqueous suspensions. Such excipients are suspending agents, for example sodium carboxymethylcellulose, methylcellulose, hydroxypropylmethyl- cellulose, sodium alginate, polyvinylpyrrolidone, gum tragacanth and gum acacia; dispersing or wetting agents may be a naturally-occurring phosphatide such as lecithin, or condensation products of an alkylene oxide with fatty acids, for example polyoxyethylene stearate, or condensation products of ethylene oxide with long chain aliphatic alcohols, for example, hepta- decaethyl-eneoxycetanol, or condensation products of ethylene oxide with partial esters de- rived from fatty acids and a hexitol such as polyoxyethylene sorbitol monooleate, or conden- sation products of ethylene oxide with partial esters derived from fatty acids and hexitol anhydrides, for example polyethylene sorbitan monooleate. The aqueous suspensions may also contain one or more coloring agents, one or more flavoring agents, and one or more sweetening agents, such as sucrose or saccharin.

The oily suspensions may contain a thickening agent, for example beeswax, hard paraffin or cetyl alchol. Sweetening agents such as those set forth above, and flavoring agents may be added to provide a palatable oral preparation. These compositions may be preserved by the addition of an anti-oxidant such as ascorbic acid. Dispersible powders and granules suitable for preparation of an aqueous suspension by the addition of water provide the active compound in admixture with a dispersing or wetting agent, suspending agent and one or more preservatives. Suitable dispersing or wetting agents and suspending agents are exemplified by those already mentioned above. Addi- tional excipients, for example, sweetening, flavoring, and coloring agents may also be present. The pharmaceutical compositions of the present invention may also be in the form of oil-in-water emulsions. The oily phase may be a vegetable oil, for example, olive oil or arachis oil, or a mineral oil, for example a liquid paraffin, or a mixture thereof. Suitable emulsify- ing agents may be naturally-occurring gums, for example gum acacia or gum tragacanth, naturally-occurring phosphatides, for example soy bean, lecithin, and esters or partial esters derived from fatty acids and hexitol anhydrides, for example sorbitan monooleate, and condensation products of said partial esters with ethylene oxide, for example polyoxyethylene sorbitan monooleate. The emulsions may also contain sweetening and flavoring Spgaηtls.and elixirs may be formulated with sweetening agents, for example glycerol, propylene glycol, sorbitol or sucrose. Such formulations may also contain a demulcent, a preservative and flavoring and coloring agents.

This suspension may be formulated according to the known methods using suitable dispersing or wetting agents and suspending agents described above. The sterile injectable preparation may also be a sterile injectable solution or suspension in a non-toxic parenterally-acceptable diluent or solvent, for example as a solution in 1 ,3-butanediol. Among the acceptable vehicles and solvents that may be employed are water, Ringer's solution, and isotonic sodium chloride solution. In addition, sterile, fixed oils are conveniently employed as solvent or suspending medium. For this purpose, any bland fixed oil may be employed using synthetic mono- or diglycerides. In addition, fatty acids such as oleic acid find use in the preparation of injectables. The compositions may also be in the form of suppositories for rectal administration of the compounds of the present invention. These compositions can be prepared by mixing the drug with a suitable non-irritating excipient which is solid at ordinary temperatures but liquid at the rectal temperature and will thus melt in the rectum to release the drug. Such materials include cocoa butter and polyethylene glycols, for example. For topical use, creams, ointments, jellies, solutions of suspensions, etc., containing the compounds of the present invention are contemplated. For the purpose of this applica- tion, topical applications shall include mouth washes and gargles.

General procedure (A) for the synthesis of compounds of the general formula (la):

Step A Step B Step C

(la)

wherein R1 , R2, R3, R4, R5 and A, are as defined for formula (I). The indole starting material can be either commercially available compounds or compounds that can be prepared following procedures described in the literature. In the general formula R5X, X represents chloride, bromide, iodide, mesylate or tosylate. The base used in step B can be NaH, K₂CO₃, NaOH, t- BuOK, DBU or an equivalent of these. The coupling agent in step D can be εDC, DIC, DCC, BOP, PyBroP or any equivalent of such which may be combined with HOBt or HOAt. If a carboxylic acid is desired as a part of R1 , R2, R3, R4, R5 or a substituent on A, a methyl- ethyl-, isopropyl- or f-butyl ester can be taken through step A to step D and subsequently be hydrolysed using standard procedures for hydrolysis of esters. The procedure is illustrated in the following example.

Step A:

The indole derivative (20 mmol) was dissolved in DCM (15 mL) and pyridine (21 mmol) was added. The solution was cooled to 0°C on an ice bath before a solution of trichloroacetyl chloride (20 mmol) in DCM (5 mL) was added over the course of 30 min. The cooling bath was removed and the reaction mixture was stirred at room temperature (typical over night). If HPLC showed unreacted indole starting material, an amount of trichloro acetyl chloride core- sponding to the amount of unreacted indole (estimated by HPLC) was added, and the mix- ture was stirred for an additional 2 hours before the solvent was removed in vacuo. The crude product was stirred with ethanol-water (1 :1 , 15 mL) for 10 min before the product was filtered off and dried in vacuo at 50°C, and used without any further purification.

Step B: To the 3-trichloroacetyl-indole derivative (0.096 mmol) from step A in NMP (0.20 mL) in a 5 mL glas vial, was added K₂CO₃ (20 mg, 0.144 mmol) and alkylating agent R5X (0.125 mmol) before the reaction mixture was shaken over night at room temperature.

Step C: To the solution from step B was added aqueous NaOH (0.10 mL, 4 N) and the reaction mixture was shaken for 1 hour whereupon aqueous HCI (0.60 mL, 1 N) was introduced. The aqueous phase was extracted with diethyl ether (2 x 1.5 mL), the two organic fractions were combined and the volatiles were removed in vacuo.

Step D:

The intermediate from step C was dissolved in NMP (0.20 mL) and HOBt (15 mg, 0.111 mmol), EDAC (37 mg, 0.192 mmol) and NH₂A (0.192 mmol) was added in sequence. The reaction mixture was heated to 120 °C for 2 hours before the reaction was allowed to cool to room temperature. The resulting mixture was applied directly on a preparative HPLC instrument (HPLC-prep. (Method D)) and fractions were collected. The fractions containing the desired compound were combined and the volatiles were removed in vacuo.

General procedure (B)

General procedure (B) for the synthesis of compounds of the general formula (la):

<^la> wherein R1 , R2, R3, R4, R5 and A, are as defined for formula (I), and Pg is a protecting group like methyl, ethyl, propyl, isopropyl, tert-butyl or benzyl. The indole starting material can be either commercially available compounds or compounds that can be prepared follow- ing procedures described in the literature. In the general formula R5X, X represents chloride, bromide, iodide, mesylate or tosylate. The base used in step A can be NaH, K₂CO₃, NaOH, t- BuOK, DBU or an equivalent of these. The coupling agent usend in step C can be EDC, DIC, DCC, BOP, PyBroP or any equivalent of such which may or may not be combined with HOBt or HOAt.

The procedure is illustrated in the following example.

Step A:

The indole derivative (0.096 mmol) dissolved in NMP (0.10 mL) was added a solution of alky- lating agent (R5X) (0.115 mmol) in NMP (0.20 mL) and subsequently solid K₂CO₃ (13.3 mg, 0.096 mmol). The reaction mixture was shaken at 40 °C for 24 hours.

Step B:

To the solution from step A was added aqueous NaOH (0.10 mL, 4 N) and the reaction mixture was shaken for two days whereupon aqueous HCI (0.60 mL, 1 N) was introduced.

PHARMACOLOGICAL METHODS

BIOLOGICAL ASSAY

Glucokinase Activity Assay (I) Glucokinase activity is assayed spectrometrically coupled to glucose 6-phosphate dehydro- genase to determine compound activation of glucokinase. The final assay contains 50 mM Hepes, pH 7.1 , 50 mM KCI, 5 mM MgCI₂, 2 mM dithiothreitol, 0.6 mM NADP, 1 mM ATP, 0.195 μM G-6-P dehydrogenase (from Roche, 127 671 ), 15 nM recombinant human glucokinase. The glucokinase is human liver glucokinase N-terminally truncated with an N- terminal His-tag ((His)₈-VEQILA Q466) and is expressed in ε.coli as a soluble protein with enzymatic activity comparable to liver extracted GK.

The purification of His-tagged human glucokinase (hGK) was performed as follows: The cell pellet from 50 ml ε. coli culture was resuspended in 5 ml extraction buffer A (25 mM HεP S, pH 8.0, 1 mM MgCI₂, 150 mM NaCI, 2 mM mercaptoethanol) with addition of 0.25 mg/ml ly- sozyme and 50 μg/ml sodium azide. After 5 minutes at room temperature 5 ml of extraction buffer B (1.5 M NaCI, 100 mM CaCI₂, 100 mM MgCI₂, 0.02 mg/ml DNase 1 , protease inhibitor tablet (Complete® 1697498): 1 tablet pr. 20 ml buffer) was added. The extract was then cen- trifugated at 15.000 g for 30 minutes. The resulting supernatant was loaded on a 1 ml Metal Chelate Affinity Chromatography (MCAC) Column charged with Ni²⁺. The column is washed with 2 volumes buffer A containing 20 mM imidazole and the bound his-tagged hGK is sub- sequently eluted using a 20 minute gradient of 20 to 500 mM imididazol in buffer A. Fractions are examined using SDS-gel-electrophoresis, and fractions containing hGK (MW: 52 KDa) are pooled. Finally a gelfiltration step is used for final polishing and buffer exhange. hGK containing fractions are loaded onto a Superdex 75 (16/60) gelfiltration column and eluted with Buffer B (25 mM HεPεS, pH 8.0, 1 mM MgCI₂, 150 mM NaCI, 1 mM Dithiothreitol). The puri- fied hGK is examined by SDS-gel electrophoresis and MALDI mass spectrometry and finally 20% glycerol is added before freezing. The yield from 50 ml ε. coli culture is generally approximately 2-3 mg hGK with a purity >90%.

The compound to be tested is added into the well in final 2.5% DMSO concentration in an amount sufficient to give a desired concentration of compound, for instance 1 , 5, 10, 25 or 50 μM. The reaction starts after glucose is added to a final concentration of 2, 5, 10 or 15 mM. The assay uses a 96-well UV plate and the final assay volume used is 200 μl/well. The plate is incubated at 25°C for 5 min and kinetics is measured at 340 nm in SpectraMax every 30 seconds for 5 minutes. Results for each compound are expressed as the fold activation of the glucokinase activity compared to the activation of the glucokinase enzyme in an assay without compound after having been subtracted from a "blank", which is without glucokinase enzyme and without compound. The compounds in each of the Examples exhibits activation of glucokinase in this assay. A compound, which at a concentration of at or below 30 μM gives 1.5 - fold higher glucokinase activity than the result from the assay without compound, is deemed to be an activator of glucokinase.

The glucose sensitivity of the compounds are measured at a compound concentration of 10 μM and at glucose concentrations of 5 and 15 mM.

Glucokinase Activity Assay (II)

Determination of glycogen deposition in isolated rat hepatocytes: Hepatocytes are isolated from rats fed ad libitum by a two-step perfusion technique. Cell viability, assessed by trypan blue exclusion, is consistently greater than 80%. Cells are plated onto collagen-coated 96-well plates in basal medium (Medium 199 (5.5 mM glucose) supplemented with 0.1 μM dexamethasone, 100 units/ml penicillin, 100 mg/ml streptomycin, 2 mM L-glutamine and 1 nM insulin) with 4 % FCS at a cell density of 30,000 cells/well. The medium is replaced with basal medium 1 hour after initial plating in order to remove dead cells. Medium is changed after 24 hours to basal medium supplemented with 9.5 mM glu- cose and 10 nM insulin to induce glycogen synthesis, and experiments are performed the next day. The hepatocytes are washed twice with prewarmed (37°C) buffer A (117.6 mM NaCI, 5.4 mM KCI, 0.82 mM Mg₂SO₄, 1.5 mM KH₂PO₄, 20 mM HEPεS, 9 mM NaHCO₃, 0.1% w/v HSA, and 2.25 mM CaCI₂, pH 7.4 at 37°C) and incubated in 100 μl buffer A containing 15 mM glucose and increasing concentrations of the test compound, such as for in- stance 1, 5, 10, 25, 50 or 100 μM, for 180 minutes. Glycogen content is measured using standard procedures(Agius, L.et al, Biochem J. 266. 91-102 (1990). A compound, which when used in this assay gives an significant increase in glycogen content compared to the result from the assay without compound, is deemed to have activity in this assay.

Glucokinase Activity Assay (III)

Stimulation of insulin secretion by glucokinase activators in INS-1E cells

The glucose responsive β-ce\\ line INS-1 E is cultivated as described by Asfari M et al., εndo- crinology, 130, 167-178 (1992). The cells are then seeded into 96 well cell culture plates and grown to a density of approximately 5 x 10⁴ per well. Stimulation of glucose dependent insulin secretion is tested by incubation for 2 hours in Krebs Ringer Hepes buffer at glucose con- centrations from 2.5 to 15 mM with or without addition of glucokinase activating compounds in concentrations of for instance 1 , 5, 10, 25, 50 or 100 μM, and the supematants collected for measurements of insulin concentrations by εLISA (n= 4). A compound, which when used in this assay gives an significant increase in insulin secretion in response to glucose compared to the result from the assay without compound, is deemed to have activity in this as- say.
