Definitions
- the present invention relates to a novel class of compounds, useful for the treatment or prevention of the metabolic syndrome, diabetes mellitus as well as diseases, disorders and medical risks related to the metabolic syndrome and diabetes mellitus. Further the invention relates to use of such compounds to manufacture a medicament.
- the metabolic syndrome is a disease characterized by a group of metabolic risk factors in a person. They include:
- Atherogenic dyslipidemia blood fat disorders — high triglycerides, low HDL cholesterol and high LDL cholesterol — that foster plaque buildups in artery walls
- Insulin resistance or glucose intolerance the body can't properly use insulin or blood sugar
- Prothrombotic state e.g., high fibrinogen or plasminogen activator inhibitor-1 in the blood
- Proinflammatory state e.g., elevated C-reactive protein in the blood
- Diabetes is a separate disease, as well as a component within the scope of the metabolic syndrome.
- One of the hallmarks of the metabolic syndrome is insulin resistance resulting in a dysfunctional glucose homeostasis.
- the insulin resistance is usually coupled with a gradual loss of pancreatic beta cell function.
- the insulin resistance results in a gradual loss of glucose uptake in the skeletal muscle cells and an increased glucose production from the liver. Both the hyperglycemia and the increased free fatty acid levels are considered to be underlying causes of the gradual loss of insulin secretion in patients with type 2 diabetes.
- the metabolic syndrome is triggering a complex series of events resulting in microvascular damage involving i.e. inflammatory changes, which result in vascular atheromatous damage.
- the first step is characterized by an endothelial dysfunction which is what sets off a series of events including e.g. adhesion molecule expression, local vascular inflammatory responses, accumulation of atherogenic lipoproteins, macrophage conversion to foam cells, and the establishment of a fibrous-lipid vascular atherosclerotic cap.
- diabetes mellitus may cause a range of other medical risks and adverse outcomes usually coupled to macrovascular as well as microvascular complications. While myocardial infarction and stroke dominate the macrovascular complications, microvascular complications usually include ocular complications (retinopathy and maculopathy), nephropathy (micro and macroalbuminuria). In about 10% of patients, such complications may present at the debut of diabetes. Diabetes is popularly classified into four major types: type 1 diabetes, type 2 diabetes, gestational diabetes, and pre-diabetes.
- the prevalence is increasing due to urbanisation and sedentary life styles.
- age ranges of 80 years and older the overall prevalence of diabetes is around 20%.
- the prevalence in males and females is similar, but the mean age of the disease is lower in males as compared with females.
- About 85-90% of all diabetes is type 2 diabetes.
- Type 1 diabetes results from the body's failure to produce insulin and these patients therefore usually need insulin therapy. Of people with diabetes, it is estimated that 15 to 10% of patients in the Western world have type 1 diabetes.
- Type 2 diabetes results from insulin resistance combined with an overproduction of insulin.
- Insulin resistance is a condition in which the body fails to properly respond to insulin.
- the majority of adult middle-aged and elderly persons who are diagnosed with diabetes have type 2 diabetes.
- Gestational diabetes which presents a risk for the fetus as well as the mother affects about 4% of all pregnant women, and is characterised by a development of diabetes during pregnancy.
- Pre-diabetes or insulin resistance is a condition that occurs when the glucose levels of a person's blood are higher than normal, but not high enough for a diagnosis of type 2 diabetes. There are at least twice as many people who can be classified as pre-diabetic, as compared to those with overt diabetes.
- ATP and its degradation product ADP (adenosine diphosphate) was not just an energy source for cells matured with the cloning of the first P2Y nucleotide receptor in 1993.
- ADP adenosine diphosphate
- the P2Y and P2X receptor family is a part of an extensive system involving a wide variety of extracellular nucleotides (ATP and ADP, UTP and UDP), their receptors, metabolizing enzymes and transporters.
- ATP is rapidly degraded by ectonucleotidases to ADP, which can act on P2Y1, P2Y12 and PY 13 receptors.
- ADP is then degraded by ecto-5 '-nucleotidase to adenosine, which in turn can activate four different adenosine receptors.
- the PY 13 receptor is activated by ADP, and has been shown to be expressed in inflammatory cells, spleen, liver, red blood cells and the brain.
- MRS2211 is a specific P2Y13 receptor antagonist (Kim et al., Biochem Pharmacol, 70 (2005) 266-274).
- WO 03/082881 discloses the use of pyroxidal-5 -phosphate derivatives as HIV integrase inhibitors. Hence, a new treatment of the metabolic syndrome, and specifically diabetes, would be advantageous and in particular compounds, compositions, and the use thereof, for said treatment.

- the inventors of the present invention found for the first time evidence for the expression of the P2Y 13 receptor in pancreatic islets of Langerhans and its beta-cells. Furthermore, the present inventors found that ADP has both a stimulatory effect on insulin via P2Yi receptors, but most importantly, that ADP inhibits insulin release via P2Yi3 receptors. The involvement of P2Y 13 receptors was an unexpected finding that has never been shown before. It demonstrates a previously unrecognised role for the P2Yi3 receptor. The P2Yi 3 antagonist MRS2211 was shown to antagonise the inhibitory effects of ADP on insulin secretion. Surprisingly, it was established that ADP constitutes an autocrine regulatory pathway for insulin regulation.
- MRS2211 blocks this autocrine pathway resulting in increased insulin secretion. MRS2211 has never before been shown to regulate insulin secretion.
- the regulation of this pathway means that MRS 2211, and analogs thereof described herein, may be used to treat diseases and disorders which would benefit from a blockade of the autocrine pathway regulated by ADP acting on P2Y13 receptors.
- diseases and disorders are the metabolic syndrome and all types of diabetes, such as diabetes mellitus type 1, diabetes mellitus type 2, gestational diabetes mellitus and pre-diabetes mellitus.
- macrovascular complications which includes, but not are limited to myocardial infarction and stroke
- microvascular complications which includes, but nor are limited to, ocular complications (retinopathy and maculopathy), nefropathy (micro and macroalbuminuria), and which may result from the metabolic syndrome and diabetes may be treated or prevented by compounds of the invention.
- MRS2211 or similar P2Y13 antagonists of the kind described herein, may be used in the treatment of diseases and disorders such as the metabolic syndrome and of all types of diabetes, such as diabetes mellitus type 1, diabetes mellitus type 2, gestational diabetes mellitus and pre-diabetes mellitus, to increase insulin secretion.
- MRS2211 augments the natural release of insulin in response to high levels of glucose, which will give an adequate dynamic release of insulin at times when it is needed (e.g. after a meal), with less risk of to high insulin levels at other times, which could result in hypoglycaemia, which is a common side effect of subcutaneous insulin therapy.

Abstract
The invention relates to compounds having the general formula (I), (II) or (III), and which are useful for the treatment or prevention of diabetes or diseases associated with the metabolic syndrome.
Description
COMPOUNDS AND USE THEREOF
FIELD OF THE INVENTION
The present invention relates to a novel class of compounds, useful for the treatment or prevention of the metabolic syndrome, diabetes mellitus as well as diseases, disorders and medical risks related to the metabolic syndrome and diabetes mellitus. Further the invention relates to use of such compounds to manufacture a medicament.
BACKGROUND OF THE INVENTION:
The metabolic syndrome is a disease characterized by a group of metabolic risk factors in a person. They include:
• Abdominal obesity (excessive fat tissue in and around the abdomen)
• Atherogenic dyslipidemia (blood fat disorders — high triglycerides, low HDL cholesterol and high LDL cholesterol — that foster plaque buildups in artery walls)
• Elevated blood pressure
• Insulin resistance or glucose intolerance (the body can't properly use insulin or blood sugar)
• Prothrombotic state (e.g., high fibrinogen or plasminogen activator inhibitor-1 in the blood)
• Proinflammatory state (e.g., elevated C-reactive protein in the blood)
People with the metabolic syndrome are at increased risk of coronary heart disease and other diseases related to plaque buildups in artery walls (e.g., stroke and peripheral vascular disease) and type 2 diabetes. The metabolic syndrome has become increasingly common in the world.
Diabetes is a separate disease, as well as a component within the scope of the metabolic syndrome. One of the hallmarks of the metabolic syndrome is insulin
resistance resulting in a dysfunctional glucose homeostasis. The insulin resistance is usually coupled with a gradual loss of pancreatic beta cell function. The insulin resistance results in a gradual loss of glucose uptake in the skeletal muscle cells and an increased glucose production from the liver. Both the hyperglycemia and the increased free fatty acid levels are considered to be underlying causes of the gradual loss of insulin secretion in patients with type 2 diabetes.
The metabolic syndrome, as well as its component risks, is triggering a complex series of events resulting in microvascular damage involving i.e. inflammatory changes, which result in vascular atheromatous damage. Usually, the first step is characterized by an endothelial dysfunction which is what sets off a series of events including e.g. adhesion molecule expression, local vascular inflammatory responses, accumulation of atherogenic lipoproteins, macrophage conversion to foam cells, and the establishment of a fibrous-lipid vascular atherosclerotic cap.
In addition to that, diabetes mellitus may cause a range of other medical risks and adverse outcomes usually coupled to macrovascular as well as microvascular complications. While myocardial infarction and stroke dominate the macrovascular complications, microvascular complications usually include ocular complications (retinopathy and maculopathy), nephropathy (micro and macroalbuminuria). In about 10% of patients, such complications may present at the debut of diabetes. Diabetes is popularly classified into four major types: type 1 diabetes, type 2 diabetes, gestational diabetes, and pre-diabetes.
The overall prevalence of diabetes in the whole population differs between countries, and in the Western world it ranges between 2-4%. The prevalence is increasing due to urbanisation and sedentary life styles. In age ranges of 80 years and older, the overall prevalence of diabetes is around 20%. The prevalence in males and females is similar, but the mean age of the disease is lower in males as compared with females. About 85-90% of all diabetes is type 2 diabetes.
Type 1 diabetes results from the body's failure to produce insulin and these patients therefore usually need insulin therapy. Of people with diabetes, it is estimated that 15 to 10% of patients in the Western world have type 1 diabetes.
Type 2 diabetes results from insulin resistance combined with an overproduction of insulin. Insulin resistance is a condition in which the body fails to properly respond to insulin. The majority of adult middle-aged and elderly persons who are diagnosed with diabetes have type 2 diabetes. Gestational diabetes, which presents a risk for the fetus as well as the mother affects about 4% of all pregnant women, and is
characterised by a development of diabetes during pregnancy. Pre-diabetes or insulin resistance is a condition that occurs when the glucose levels of a person's blood are higher than normal, but not high enough for a diagnosis of type 2 diabetes. There are at least twice as many people who can be classified as pre-diabetic, as compared to those with overt diabetes.
More than 65% of people who suffer from diabetes, die as an result of its cardiovascular consequences, usually coronary heart disease or stroke. With diabetes, cardiovascular complications occur earlier in life and more often result in death. By managing diabetes, people with diabetes can reduce their risk of heart attacks. In a normal individual, not suffering from diabetes, an increased level of glucose in the blood will result in the release of insulin from the beta-cells in the islets of Langerhans in the pancreas. The effects of insulin reduce the level of glucose in the blood. In a patient, with one of the forms of diabetes mentioned above, this release of insulin is insufficient. Evidence for biological activity of extracellular nucleotides followed the notion that ATP (adenosine triphosphate) was a non-adrenergic, non-cholinergic neurotransmitter. The idea that ATP and its degradation product ADP (adenosine diphosphate) was not just an energy source for cells matured with the cloning of the first P2Y nucleotide receptor in 1993. Now, the P2Y and P2X receptor family is a part of an extensive system involving a wide variety of extracellular nucleotides (ATP and ADP, UTP and UDP), their receptors, metabolizing enzymes and transporters.
High levels of glucose stimulates the release of ATP to the extracellular spatium from several cell types such as endothelial cells, blood vessels, mesangial cells, macrophages and beta-cells 1-5. The net pharmacological effects of extracellular ATP are difficult to predict. ATP by itself can stimulate P2Y2, P2Y4 (in rodents), P2Y11 and P2X1-P2X7 receptors present on the cell surfaceό. Furthermore, ATP is rapidly degraded by ectonucleotidases to ADP, which can act on P2Y1, P2Y12 and PY 13 receptors. ADP is then degraded by ecto-5 '-nucleotidase to adenosine, which in turn can activate four different adenosine receptors. The PY 13 receptor is activated by ADP, and has been shown to be expressed in inflammatory cells, spleen, liver, red blood cells and the brain. MRS2211 is a specific P2Y13 receptor antagonist (Kim et al., Biochem Pharmacol, 70 (2005) 266-274).
Various P2Y and P2X receptor antagonists have been disclosed by Brown et al in Drug Development Research 53:281-291 (2001), by Kim et al in J. Med. Chem.
2001, 44, 340-349, by Kim et al in Drug Development Research 45:52-66 (1998) and by Ziganshin et al in Pharmaceutical Chemistry Journal 1998, 32:8, 399-401.
WO 03/082881 discloses the use of pyroxidal-5 -phosphate derivatives as HIV integrase inhibitors. Hence, a new treatment of the metabolic syndrome, and specifically diabetes, would be advantageous and in particular compounds, compositions, and the use thereof, for said treatment.

DETAILED DESCRIPTION OF THE INVENTION:
Definitions:
The term "addition salt" is intended to mean salts formed by the addition of a acid, such as organic or inorganic acids, or by addition of a base. The organic acid may be, but is not limited to, acetic, propanoic, methanesulfonic, benzenesulfonic, lactic, malic, citric, tartaric, succinic or maleic acid. The inorganic acid may be, but is not limited to, hydrochloric, hydrobromic, sulfuric, nitric acid or phosphoric acid. The base may be, but is not limited to, ammonia and hydroxides of alkali or alkaline earth metals. The term addition salt also comprises the hydrates and solvent addition forms, such as hydrates and alcoholates.
As used herein, "halo" or "halogen" refers to fiuoro, chloro, bromo, and iodo. As used herein, "alkyl", "alkylenyl" or "alkylene" used alone or as a suffix or prefix, is intended to include both branched and straight chain saturated aliphatic hydrocarbon groups having from 1 to 12 carbon atoms or if a specified number of carbon atoms is provided then that specific number would be intended. For example "Cl-6 alkyl" denotes alkyl having 1, 2, 3, 4, 5 or 6 carbon atoms. When the specific number denoting the alkyl-group is the integer 0 (zero), a hydrogen-atom is intended as the substituent at the position of the alkyl-group. For example, "N(CO alkyl)2" is equivalent to "NH2" (amino). When the specific number denoting the alkylenyl or alkylene-group is the integer 0 (zero), a bond is intended to link the groups onto which the alkylenyl or alkylene-group is substituted. For example, "NH(CO alkylene)NH2" is equivalent to "NHNH2" (hydrazino). As used herein, the groups linked by an alkylene or alkylenyl-group are intended to be attached to the first and to the last carbon of the alkylene or alkylenyl-group. In the case of methylene, the first and the last carbon is the same. For example, "H2N(C2 alkylene)NH2", "H2N(C3 alkylene)NH2", "N(C4 alkylene)", "N(C5 alkylene)" and "N(C2 alkylene)2NH" is equivalent to 1,2-diamino ethane, 1,3-diamino propane, pyrrolidinyl, piperidinyl and piperazinyl, repectively.
Examples of alkyl include, but are not limited to, methyl, ethyl, n-propyl, i- propyl, n-butyl, i-butyl, sec-butyl, t-butyl, pentyl, and hexyl.
Examples of alkylene or alkylenyl include, but are not limited to, methylene, ethylene, propylene, and butylene. As used herein, "alkoxy" or "alkyloxy" is intended to mean an alkyl group as defined above with the indicated number of carbon atoms attached through an oxygen bridge.

Similarly, "alkylthio" or "thioalkoxy" represent an alkyl group as defined above with the indicated number of carbon atoms attached through a sulphur bridge.
As used herein, "fiuoroalkyl", "fluoroalkylene" and "fluoroalkoxy", used alone or as a suffix or prefix, refers to groups in which one, two, or three of the hydrogen(s) attached to the carbon(s) of the corresponding alkyl, alkylene and alkoxy-groups are replaced by fiuoro. Examples of fiuoroalkyl include, but are not limited to, trifluoromethyl, difluoromethyl, fluoromethyl, 2,2,2-trifluoroethyl, 2-fluoroethyl and 3- fluoropropyl.
The inventors of the present invention found for the first time evidence for the expression of the P2Y13 receptor in pancreatic islets of Langerhans and its beta-cells. Furthermore, the present inventors found that ADP has both a stimulatory effect on insulin via P2Yi receptors, but most importantly, that ADP inhibits insulin release via P2Yi3 receptors. The involvement of P2Y13 receptors was an unexpected finding that has never been shown before. It demonstrates a previously unrecognised role for the P2Yi3 receptor. The P2Yi3 antagonist MRS2211 was shown to antagonise the inhibitory effects of ADP on insulin secretion. Surprisingly, it was established that ADP constitutes an autocrine regulatory pathway for insulin regulation. When islets are stimulated with glucose, ADP levels outside the beta-cells are increased and turns off the insulin secretion via stimulation of the P2Y13 receptor. MRS2211 blocks this autocrine pathway resulting in increased insulin secretion. MRS2211 has never before been shown to regulate insulin secretion. The regulation of this pathway means that MRS 2211, and analogs thereof described herein, may be used to treat diseases and disorders which would benefit from a blockade of the autocrine pathway regulated by ADP acting on P2Y13 receptors. Without limitation examples of such diseases and disorders are the metabolic syndrome and all types of diabetes, such as diabetes mellitus type 1, diabetes
mellitus type 2, gestational diabetes mellitus and pre-diabetes mellitus. Further complications such as macrovascular complications, which includes, but not are limited to myocardial infarction and stroke, and microvascular complications, which includes, but nor are limited to, ocular complications (retinopathy and maculopathy), nefropathy (micro and macroalbuminuria), and which may result from the metabolic syndrome and diabetes may be treated or prevented by compounds of the invention.
As shown in fig. 2, Langerhans islets, stimulated with glucose, release insulin both at the glucose concentrations 8.3 and 20 mM, thus mimicking the normal situation in vivo. When the P2Y13 antagonist MRS2211 was added, the glucose stimulated release of insulin was significantly increased. Thus, MRS2211, or similar P2Y13 antagonists of the kind described herein, may be used in the treatment of diseases and disorders such as the metabolic syndrome and of all types of diabetes, such as diabetes mellitus type 1, diabetes mellitus type 2, gestational diabetes mellitus and pre-diabetes mellitus, to increase insulin secretion. Furthermore, MRS2211 augments the natural release of insulin in response to high levels of glucose, which will give an adequate dynamic release of insulin at times when it is needed (e.g. after a meal), with less risk of to high insulin levels at other times, which could result in hypoglycaemia, which is a common side effect of subcutaneous insulin therapy.
Ivanov at el (J Comput Aided MoI Des (2006) 20:417-426) and Costanzi et al (J. Med. Chem. 2004, 47, 5393-5404) have disclosed advanced homology models of
P2Y13 based on the known structure of rhodopsin, a protein structural related to P2Y13. Further, it was possible to draw conclusions about structure activity relationships (SAR: s) of the activity of MRS2211 and structurally related analogues on P2Y13 and other P2-receptors from reports in the literature (Kim et al., Biochem Pharmacol, 70 (2005) 266-274, Brown et al in Drug Development Research 53:281-291 (2001), Kim et al in J. Med. Chem. 2001, 44, 340-349, Kim et al in Drug Development Research 45:52- 66 (1998) and Ziganshin et al in Pharmaceutical Chemistry Journal 1998, 32:8, 399- 401).
By use of this advanced homology model of P2Y13 and representative conformers of MRS2211, it was possible to identify interactions important to the binding of MRS2211 to P2Y13 and to identify structural requirements of P2Y13- antagonists. Thereby, it was possible to put forward a generic structure deemed to cover compounds able to bind to P2Y13 and act as antagonists. This generic structure was then adjusted in accordance with the SAR:s.

P 2Y receptor expression in mouse islets and beta-cells
Among the P2Y receptors sensitive to purines the highest mRNA levels were found for the ADP receptor P2Y1 and P2Y13 (6.7 ± 0.6 x 10-3 and 1.3 ± 0.6 x 10-3 respectively in mouse pancreatic islets (ratio of GAPDH mRNA expression) and 4.0 ± 3.0 x 10-3 and 1.8 ± 0.3 x 10-3 respectively in mouse beta cells, see fig. 1). The ATP/UTP receptor P2Y2 could only be detected at thousand times lower levels (0.003 ± 0.0004 x 10-3 in mouse pancreatic islets and 0.009 ± 0.004 x 10-3 in mouse beta cells,
see figure 1). The ADP receptor P2Y12 and the ATP/UTP receptor P2Y4 could not be detected at all.
Effects ofglucos on insulin and glucagon secretion in the presence of the P2Y13 antagonist MRS2211
MRS2211 is a selective antagonist blocking the binding of ADP to the P2Y13 receptor. Addition of 10 μM MRS 2211 to pancreatic islets augmented the insulin- releasing effect of 8.3 mM glucose from 0.72±0.08 to 1.43=1=0.11 ng/islet*hour (fig. 2). Raising the glucose level to 20 mM resulted as expected in increased insulin release to 1.96±0.15 ng/islet*hour. In the presence 10 μM MRS2211 this increase was further increased to 2.70±0.19 ng/islet*hour (fig 2). 30 μM MRS2211 had similar effects.
Effects of ADP on insulin secretion
The stable ADP analogue 2-MeSADP alone did not alter insulin secretion from mouse pancreatic islets induced by 8.3 mM glucose. Pre-treatment with the selective P2Y1 receptor antagonist MRS2179 resulted in a marked significant decrease in insulin secretion (fig 3). In contrast, pre-treatment with the selective P2Y13 receptor antagonist MRS2211 resulted in a marked significant increase in insulin secretion (fig 3).
