Definitions

  • the present invention relates to the novel use of CB x modulators as K A TP channel modulators.
  • the present invention also relates to a method of treating, preventing, delaying progression of, delaying onset of and/or inhibiting obesity, diabetes mellitus, metabolic syndrome, syndrome X, insulinoma, familial hyperinsulemic hypoglycemia, male pattern baldness, detrusor hyperreactivity, asthma, neuroprotection, epilepsy, analgesia, cardioprotection, angina, cardioplegia, arrhythmia, coronary spasm, peripheral vascular disease, cerebral vasospasm, appetite regulation, neurodegeneration, pain - including neuropathic pain and chronic pain - and impotence in mammals and humans comprising administering to a subject in need thereof an effective amount of at least one CB x modulator as K A TP channel modulator.
  • Obesity according to the present invention is meant to comprise any increase in body fat that results in increased bodyweight, preferably comprising but not limited to the medical definition of obesity.
  • obesity also comprises non-medical, e.g. cosmetic overweight.
  • the invention thus also relates to non-medical weight loss, such as cosmetic weight loss and includes improving bodily appearance in general.
  • non-medical weight loss such as cosmetic weight loss and includes improving bodily appearance in general.
  • obesity is usually understood to denominate a body weight more than 20 % above the ideal body weight.
  • Even in this more narrowed sense obesity is a major health concern in Western societies. It is estimated that about 97 million adults in the United States are overweight or obese.
  • Obesity is largely the result of a positive energy balance as a consequence of increased ratio of caloric intake to energy expenditure.
  • the molecular factors regulating food intake and body weight are incompletely understood, but several genetic factors have been identified.
  • Obesity causes or exacerbates many health problems, both independently and in association with other diseases.
  • the medical problems associated with obesity which can be serious and life-threatening, generally include hypertension; type Il diabetes mellitus; elevated plasma insulin concentrations; insulin resistance; dyslipidemias; hyperlipidemia; endometrial, breast, prostate and colon cancer; osteoarthritis; respiratory complications, such as obstructive sleep apnea; cholelithiasis; gallstones; arteriosclerosis; heart disease; abnormal heart rhythms; and heart arrythmias.
  • Obesity is further associated with premature death and with a significant increase in mortality and morbidity from stroke, myocardial infarction, congestive heart failure, coronary heart disease, and sudden death.
  • Obesity is often treated by encouraging patients to lose weight by reducing their food intake or by increasing their exercise level and therefore increasing their energy output.
  • a sustained weight loss of 5% to 10% of body weight has been shown to improve the co-morbidities associated with obesity, such as diabetes and hypertension, and can lead to improvement of obesity-related conditions such as osteoarthritis, sleep apnea and pulmonary and cardiac dysfunction.
  • Weight loss drugs that are currently used in monotherapy for the treatment of obesity have limited efficacy and significant side effects. During chronic treatment periods of greater than six months the efficacy of most agents decreases yielding no more than 10% body weight loss compared to control. Obese humans can easily mass over 150 kg and would, therefore, need to lose more than 50% of their body mass to return to a normal body mass.
  • the term "metabolic syndrome” is meant to cover a complex of clinical pictures which - besides central obesity - mainly comprises hypertension, in particular arterial hypertension; insulin resistance, in particular type Il diabetes; glucose intolerance; dyslipoproteinaemia, in particular as hypertriglyceridaemia, accompanied by dyslipoproteinaemia occurring with lowered HDL-cholesterol, and also hyperuricaemia, which can lead to gout.
  • the metabolic syndrome is closely linked to insulin resistance. Some people are genetically predisposed to insulin resistance. Acquired factors, such as excess body fat and physical inactivity, can elicit insulin resistance and the metabolic syndrome in these people. Most people with insulin resistance have central obesity.
  • the biologic mechanisms at the molecular level between insulin resistance and metabolic risk factors are not fully understood and appear to be complex.
  • One group of people at risk for developing metabolic syndrome is those with diabetes who have a defect in insulin action and cannot maintain a proper level of glucose in their blood.
  • a third group is heart attack survivors who, unlike hypertensives, have hyperinsulinemia without having abnormal glucose levels.
  • the metabolic syndrome has become increasingly common in higher developed countries like the United States, where it is estimated that about 20-25 percent of US adults have it. There are no well-accepted criteria for diagnosing the metabolic syndrome.
  • the term “syndrome X” is closely related to the term “metabolic syndrome” and usually is supposed to denominate the identical disease or condition. According to information from the American Heart Association, the term “Syndrome X” refers, however, additionally to a heart condition where chest pain and electrocardiographic changes that suggest ischemic heart disease are present, but where there are no angiographic findings of coronary disease. Patients with cardiac syndrome X also sometimes have lipid abnormalities.
  • ATP-sensitive potassium channel (K A TP channel) modulation has been linked to several potential clinical uses including diabetes, insulinoma, familial hyperinsulemic hypoglycemia, male pattern baldness, detrusor hyperreactivity, asthma, neuroprotection, epilepsy, analgesia, cardioprotection, angina, cardioplegia, arrhythmia, coronary spasm, hypertension, peripheral vascular disease, cerebral vasospasm, appetite regulation, neurodegeneration, pain - including neuropathic pain and chronic pain - and impotence (ref. Jahangir et al. J. MoI. Cell. Cardiology, 2005, 39, 99-1 12 and references cited therein).
  • K A TP channel openers and their potential use in the inhibition of insulin secretion and/or the treatment of metabolic disorders are known e.g. from documents US 6,492,130; WO 02/00223; WO 02/00665 or from R. D. Carr et al., Diabetes 52 (2003) 2513-2518 or J. B. Hansen et al., Current Medicinal Chemistry H (2004) 1595-1615.
  • the K A TP channel couples glucose metabolism to insulin secretion. Defective regulation of K A TP channel activity has been reported to contribute to the etiology of type 2 diabetes (ref. Ashcroft, J. Clin. Investig. 2005, 1 15 (8), 2047-2057 and references cited therein).
  • the SUR1 regulatory subunit is in particular found in pancreas and brain (ref. Aguilar-Bryan et al., Science 1995, 268, 423-426).
  • the K A TP Kir6.2/SUR1 combination exists in the pancreas.
  • Insulin is the main hormone involved in blood glucose homeostasis. Insulin is involved in the regulation of glycaemia and as a consequence related to type I and type
  • the regulation of insulin secretion will be useful in the treatment of diseases such as diabetus mellitus type I, diabetus mellitus type II, obesity, metabolic syndrome and syndrome X.
  • CB x modulators act as K A TP channel modulators.
  • CB x modulators can be used for and against all illnesses and diseases which require opening of K A TP channels.
  • CB x modulators act can be used for treating, preventing, delaying progression of, delaying onset of and/or inhibiting obesity, diabetes mellitus, metabolic syndrome, syndrome X, insulinoma, familial hyperinsulemic hypoglycemia, male pattern baldness, detrusor hyperreactivity, asthma, neuroprotection, epilepsy, analgesia, cardioprotection, angina, cardioplegia, arrhythmia, coronary spasm, peripheral vascular disease, cerebral vasospasm, appetite regulation, neurodegeneration, pain - including neuropathic pain and chronic pain - and impotence in mammals and humans.

Description

USE OF CBX CANNABINOID RECEPTOR MODULATORS AS POTASSIUM CHANNEL MODULATORS
FIELD OF THE INVENTION
The present invention relates to the novel use of CBx modulators as KATP channel modulators. The present invention also relates to a method of treating, preventing, delaying progression of, delaying onset of and/or inhibiting obesity, diabetes mellitus, metabolic syndrome, syndrome X, insulinoma, familial hyperinsulemic hypoglycemia, male pattern baldness, detrusor hyperreactivity, asthma, neuroprotection, epilepsy, analgesia, cardioprotection, angina, cardioplegia, arrhythmia, coronary spasm, peripheral vascular disease, cerebral vasospasm, appetite regulation, neurodegeneration, pain - including neuropathic pain and chronic pain - and impotence in mammals and humans comprising administering to a subject in need thereof an effective amount of at least one CBx modulator as KATP channel modulator.
BACKGROUND OF THE INVENTION
Obesity according to the present invention is meant to comprise any increase in body fat that results in increased bodyweight, preferably comprising but not limited to the medical definition of obesity. Thus, in accordance with the invention, obesity also comprises non-medical, e.g. cosmetic overweight. The invention thus also relates to non-medical weight loss, such as cosmetic weight loss and includes improving bodily appearance in general. In a more narrowed sense, obesity is usually understood to denominate a body weight more than 20 % above the ideal body weight. Even in this more narrowed sense, obesity is a major health concern in Western societies. It is estimated that about 97 million adults in the United States are overweight or obese. Obesity is largely the result of a positive energy balance as a consequence of increased ratio of caloric intake to energy expenditure. The molecular factors regulating food intake and body weight are incompletely understood, but several genetic factors have been identified.
Epidemiological studies have shown that increasing degrees of overweight and obesity are important predictors of decreased life expectancy. Obesity causes or exacerbates many health problems, both independently and in association with other diseases. The medical problems associated with obesity, which can be serious and life-threatening, generally include hypertension; type Il diabetes mellitus; elevated plasma insulin concentrations; insulin resistance; dyslipidemias; hyperlipidemia; endometrial, breast, prostate and colon cancer; osteoarthritis; respiratory complications, such as obstructive sleep apnea; cholelithiasis; gallstones; arteriosclerosis; heart disease; abnormal heart rhythms; and heart arrythmias. Obesity is further associated with premature death and with a significant increase in mortality and morbidity from stroke, myocardial infarction, congestive heart failure, coronary heart disease, and sudden death.
Obesity is often treated by encouraging patients to lose weight by reducing their food intake or by increasing their exercise level and therefore increasing their energy output. A sustained weight loss of 5% to 10% of body weight has been shown to improve the co-morbidities associated with obesity, such as diabetes and hypertension, and can lead to improvement of obesity-related conditions such as osteoarthritis, sleep apnea and pulmonary and cardiac dysfunction.
Weight loss drugs that are currently used in monotherapy for the treatment of obesity have limited efficacy and significant side effects. During chronic treatment periods of greater than six months the efficacy of most agents decreases yielding no more than 10% body weight loss compared to control. Obese humans can easily mass over 150 kg and would, therefore, need to lose more than 50% of their body mass to return to a normal body mass.
The term "metabolic syndrome" is meant to cover a complex of clinical pictures which - besides central obesity - mainly comprises hypertension, in particular arterial hypertension; insulin resistance, in particular type Il diabetes; glucose intolerance; dyslipoproteinaemia, in particular as hypertriglyceridaemia, accompanied by dyslipoproteinaemia occurring with lowered HDL-cholesterol, and also hyperuricaemia, which can lead to gout. According to information from the American Heart Association, the metabolic syndrome is closely linked to insulin resistance. Some people are genetically predisposed to insulin resistance. Acquired factors, such as excess body fat and physical inactivity, can elicit insulin resistance and the metabolic syndrome in these people. Most people with insulin resistance have central obesity. The biologic mechanisms at the molecular level between insulin resistance and metabolic risk factors are not fully understood and appear to be complex. One group of people at risk for developing metabolic syndrome is those with diabetes who have a defect in insulin action and cannot maintain a proper level of glucose in their blood. Another is people, mainly those with high blood pressure, who are non-diabetic and insulin-resistant but who compensate by secreting large amounts of insulin. This condition is known as hyperinsulinemia. A third group is heart attack survivors who, unlike hypertensives, have hyperinsulinemia without having abnormal glucose levels. The metabolic syndrome has become increasingly common in higher developed countries like the United States, where it is estimated that about 20-25 percent of US adults have it. There are no well-accepted criteria for diagnosing the metabolic syndrome. The criteria proposed by the Third Report of the National Cholesterol Education Program (NCEP) Expert Panel on Detection, Evaluation, and Treatment of High Blood Cholesterol in Adults (Adult Treatment Panel III) are the most current and widely used. According to the ATP III criteria, the metabolic syndrome is identified by the presence of three or more of these following components:
a. Central obesity as measured by waist circumference (Men - Greater than 40 inches; Women - Greater than 35 inches).
b. Fasting blood triglycerides greater than or equal to 150 mg/dL.
c. Blood HDL cholesterol (Men - Less than 40 mg/dL; Women - Less than 50 mg/dL)
d. Blood pressure greater than or equal to 130/85 mmHg.
e. Fasting glucose greater than or equal to 1 10 mg/dL.
The term "syndrome X" is closely related to the term "metabolic syndrome" and usually is supposed to denominate the identical disease or condition. According to information from the American Heart Association, the term "Syndrome X" refers, however, additionally to a heart condition where chest pain and electrocardiographic changes that suggest ischemic heart disease are present, but where there are no angiographic findings of coronary disease. Patients with cardiac syndrome X also sometimes have lipid abnormalities.
Therefore, it was an objective of the present invention to provide a more effective and/or more selective therapy for obesity, diabetes mellitus, metabolic syndrome, syndrome X, insulinoma, familial hyperinsulemic hypoglycemia, male pattern baldness, detrusor hyperreactivity, asthma, neuroprotection, epilepsy, analgesia, cardioprotection, angina, cardioplegia, arrhythmia, coronary spasm, peripheral vascular disease, cerebral vasospasm, appetite regulation, neurodegeneration, pain - including neuropathic pain and chronic pain - and impotence.
ATP-sensitive potassium channel (KATP channel) modulation has been linked to several potential clinical uses including diabetes, insulinoma, familial hyperinsulemic hypoglycemia, male pattern baldness, detrusor hyperreactivity, asthma, neuroprotection, epilepsy, analgesia, cardioprotection, angina, cardioplegia, arrhythmia, coronary spasm, hypertension, peripheral vascular disease, cerebral vasospasm, appetite regulation, neurodegeneration, pain - including neuropathic pain and chronic pain - and impotence (ref. Jahangir et al. J. MoI. Cell. Cardiology, 2005, 39, 99-1 12 and references cited therein).
KATP channel openers and their potential use in the inhibition of insulin secretion and/or the treatment of metabolic disorders are known e.g. from documents US 6,492,130; WO 02/00223; WO 02/00665 or from R. D. Carr et al., Diabetes 52 (2003) 2513-2518 or J. B. Hansen et al., Current Medicinal Chemistry H (2004) 1595-1615.
The beneficial role of the specific KATP channel opener diazoxide in the treatment of i.a. the metabolic syndrome is known e.g. from documents US 5,284,845 or US
6,197,765 or from R. Alemzadeh et al., Endocrinology 133 (2) (1993) 705-712 or R.
Alemzadeh et al., Journal of Clinical Endocrinology and Metabolism 83 (6) (1998)
191 1-1915.
The KATP channel couples glucose metabolism to insulin secretion. Defective regulation of KATP channel activity has been reported to contribute to the etiology of type 2 diabetes (ref. Ashcroft, J. Clin. Investig. 2005, 1 15 (8), 2047-2057 and references cited therein). The KATP channel is an octameric complex of 4 Kirδ.x (x = 1 or 2) and 4 regulatory SURy subunits (Y = 1 , 2A or 2B). The SUR1 regulatory subunit is in particular found in pancreas and brain (ref. Aguilar-Bryan et al., Science 1995, 268, 423-426). The KATP Kir6.2/SUR1 combination exists in the pancreas. Its structure has been determined recently (ref. Mikhailov, EMBO Journal, 2005, 24, (23), 4166-4175). Recent advances in the discovery of ATP-sensitive potassium channel openers have been reviewed (Pirotte et al., Exp OpIn. Ther. Patents 2005, 15 (5), 497-504).
Insulin is the main hormone involved in blood glucose homeostasis. Insulin is involved in the regulation of glycaemia and as a consequence related to type I and type
Il diabetes. Additionally, insulin is involved in lipogenesis and weight gain, provoking an anorexigenic action as it provokesa satiety when acting in the brain (ref. Juan-Pico et al., Cell Calcium 2006, 39, 155-163 and references cited therein).
Therefore, the regulation of insulin secretion will be useful in the treatment of diseases such as diabetus mellitus type I, diabetus mellitus type II, obesity, metabolic syndrome and syndrome X.
The endocannabinoid system (refs. (a) De Petrocellis, L. et al., Br. J. Pharmacol.
2004 141 , 765-774; (b) Di Marzo, V. et al., Nature Rev. Drug Discov. 2004, 3, 771-784; (c) Lambert, D. M. and Fowler, CJ. J. Med. Chem. 2005, 48, 5059-5087) has been reported to play a role in the physiological regulation of food intake, energy balance and glucose and lipid metabolism. The existence of both cannabinoid CB1 and CB2 receptors has been demonstrated in the endocrine pancreas. It has been reported that the endogenous CB1/2 receptor agonist 2-arachidonoyl glycerol (2-AG) (Figure 2) through CB2 receptors regulates [Ca2+], signals in β-cells in the endocrine pancreas and as a consequence (as was concluded by Juan-Pico et al.) it decreases insulin secretion (ref. Juan-Pico et al., Cell Calcium 2006, 39, 155-163). Recent advances in the field of CB2 receptor ligands have been reviewed by Raitio et al. (Curr. Med. Chem. 2005, 12, 1217-1237).
It has now surprisingly been found that the quantitative effects observed within the use of CBx modulators in the indications mentioned herein are greater than expected and explainable by a single mechanism of CBx modulation. By a more thorough investigation, it has been proved and demonstrated that CBx modulators act as KATP channel modulators. Hence, CBx modulators can be used for and against all illnesses and diseases which require opening of KATP channels. More specifically, CBx modulators act can be used for treating, preventing, delaying progression of, delaying onset of and/or inhibiting obesity, diabetes mellitus, metabolic syndrome, syndrome X, insulinoma, familial hyperinsulemic hypoglycemia, male pattern baldness, detrusor hyperreactivity, asthma, neuroprotection, epilepsy, analgesia, cardioprotection, angina, cardioplegia, arrhythmia, coronary spasm, peripheral vascular disease, cerebral vasospasm, appetite regulation, neurodegeneration, pain - including neuropathic pain and chronic pain - and impotence in mammals and humans.
SUMMARY OF THE INVENTION
In a first aspect, the present invention relates to the use of at least one CBx modulator wherein the CBx modulator is selected from the group consisting of CB1 agonists; CB2 agonists; CB2 partial agonists; CB2 antagonists; CB2 inverse agonists; and dually acting compounds which are both a CB1 agonist and a CB2 agonist; and mixtures thereof, as KATP channel modulator for the prophylaxis, treatment, delayed progression, delayed onset and/or inhibition of obesity, diabetes mellitus, metabolic syndrome, syndrome X, insulinoma, familial hyperinsulemic hypoglycemia, male pattern baldness, detrusor hyperreactivity, asthma, neuroprotection, epilepsy, analgesia, cardioprotection, angina, cardioplegia, arrhythmia, coronary spasm, peripheral vascular disease, cerebral vasospasm, appetite regulation, neurodegeneration, pain - including neuropathic pain and chronic pain - and impotence in mammals and humans.
In a second aspect, the invention also relates to a method of treating, preventing, delaying progression of, delaying onset of and/or inhibiting obesity, diabetes mellitus, metabolic syndrome, syndrome X, insulinoma, familial hyperinsulemic hypoglycemia, male pattern baldness, detrusor hyperreactivity, asthma, neuroprotection, epilepsy, analgesia, cardioprotection, angina, cardioplegia, arrhythmia, coronary spasm, peripheral vascular disease, cerebral vasospasm, appetite regulation, neurodegeneration, pain - including neuropathic pain and chronic pain - and impotence in mammals and humans comprising administering to a subject in need thereof an effective amount of at least one CBx modulator wherein the CBx modulator is selected from the group consisting of CB1 agonists; CB2 agonists; CB2 partial agonists; CB2 antagonists; CB2 inverse agonists; and dually acting compounds which are both a CB1 agonist and a CB2 agonist; and mixtures thereof, and wherein the CBx modulator has KATP channel modulating properties. DETAILED DESCRIPTION OF THE INVENTION
In one embodiment of the present invention, the CBx modulators are used as KATP channel modulators for the prophylaxis, treatment, delayed progression, delayed onset and/or inhibition of obesity, diabetes mellitus, metabolic syndrome, syndrome X, insulinoma, familial hyperinsulemic hypoglycemia, male pattern baldness, detrusor hyperreactivity, asthma, neuroprotection, epilepsy, analgesia, cardioprotection, angina, cardioplegia, arrhythmia, coronary spasm, peripheral vascular disease, cerebral vasospasm, appetite regulation, neurodegeneration, pain - including neuropathic pain and chronic pain - and impotence in mammals and humans. More specifically, if the CBx modulators are used for the prophylaxis, treatment, delayed progression, delayed onset and/or inhibition of the metabolic syndrome and/or syndrome X, it is understood that the metabolic syndrome and/or syndrome X comprise disorders or diseases selected from the group consisting of hypertension, in particular arterial hypertension; insulin resistance, in particular diabetes mellitus type II; glucose intolerance; dyslipoproteinaemia, in particular as hypertriglyceridaemia accompanied by dyslipoproteinaemia occurring with lowered HDL-cholesterol and hyperuricaemia.
Suitable KATP channel modulators are preferably compounds which have effects as full or partial openers at the Kir6.2/SUR1 KATP channel, and/or the Kir6.2/ SUR2 KATP channel. Effective are those compounds which exhibit an IC50 value [μmol] of less than 50 in a test for the affinity of the compounds in binding to the sulfonylurea (= SUR) and potassium channel opener site (= KCO) of rat and/or human isoforms of SUR1 and/or SUR2 - e.g. the test model provided below. Compounds with an effect as full or partial openers at the Kir6.2/SUR1 KATP channel, in particular as selective openers at the Kir6.2/SUR1 KATp channel are preferred. A compound with an effect as full or partial opener at the Kir6.2/SUR1 KATp channel is understood to be selective if its IC50 value at the Kir6.2/SUR1 KATp channel, as measured in the aforementioned binding test, is less than half, more preferred only a quarter, of the IC50 value of that same compound at the Kir6.2/SUR2 KATP channel.
It has surprisingly been found that CBx modulators from distinct structural classes act as potent and SUR1/SUR2 selective KATp Kir6.2 channel modulators. CBy modulators in this invention are CB1 agonists; CB2 agonists; CB2 partial agonists; CB2 antagonists; CB2 inverse agonists; and dually acting compounds which are both a CB1 agonist and a CB2 agonist; and mixtures thereof. KATP channel modulators are preferably SUR1 /KATP Kir6.2 channel modulators, in particular SUR1/ KATP Kir6.2 channel modulators or partial SUR1 /KATP Kir6.2 channel modulators. Preferred CBx modulators are compounds which have effects as modulators at the Kir6.2/SUR1 KATp channel, at the Kir6.2/SUR2B KATP channel, the Kir6.1/ SUR2B KATP channel, and/or at the Kir6.2/SUR2A KATP channel.
In a preferred embodiment of the present invention, the KATp channel modulator is a KATp channel opener.

Description of the pharmacological test methods
1. In vitro binding affinity of the test compounds to rodent KATP channels
Competitive binding experiments were performed to characterize the affinity of the test compounds for the binding sites for sulfonylureas and KATP channel openers (= KCOs) on hamster SUR1. To assess the affinity for the sulfonylurea site membranes from COS-cells transiently expressing hamster SUR1 were incubated in the presence of [3H]glibenclamide with increasing concentrations of test compounds. The affinity for binding to the KCO site was assessed by incubations in the additional presence of 100 μM MgATP (see Schwanstecher M., et al. Naunyn-Schmiedeberg's Arch. Pharmacol. 343 (1991 ) 83-89 and Schwanstecher M. et al., EMBO J. 17 (1998) 5529-5535 (= Schwanstecher et al., 1998)). For each test compound 4 displacement curves were measured (+/- MgATP from the human and hamster isoform). Per curve 9-15 distinct concentrations were tested covering the relevant range. All measurements were repeated at least 5 times in independent experiments.
Similar to SUR1 (see above) competitive binding experiments were performed to characterize the affinity of the test compounds for the binding sites for sulfonylureas and KCOs on rat SUR2A. The affinity for the KCO site on SUR2A was assessed by displacement of [3H]PI 075 (see Schwanstecher et al., 1998; Dόrschner H. et al. MoI. Pharmacol. 55 (1999) 1060-1066 (= Dόrschner et al., 1999)). The affinity of [3H]glibenclamide for the human SUR2 isoforms, however, is too weak to allow direct detection of binding using filtration assays. Therefore, two strategies can be used to detect binding to the sulfonylurea site on SUR2A. First, binding can be detected indirectly through allosteric displacement of [3H]PI 075 (Dόrschner et al., 1999). Second, a mutated SUR2A (SUR2AY1205s, see above) with increased affinity for [3H]glibenclamide allowing direct displacement of this tracer can be used. This second approach was chosen to enable discrimination between allosteric and competitive interaction with the KCO site and make sure that binding of ligands which do not induce allosteric displacement are not missed.
Membranes from COS-cells transiently expressing rat SUR2A were incubated in the presence of the radioligands with increasing concentrations of test compounds as described above. The affinity for binding to the KCO site was assessed by incubations in the additional presence of 100 μM MgATP (Schwanstecher et al., 1991 and 1998). For each test compound 4 displacement curves were measured (displacement of [3H]PI 075 from the rat isoform of the wild type receptor and displacement of [3H]glibenclamide from the rat isoform of SUR2AY1205s)- Per curve 9-15 distinct concentrations were tested covering the relevant range. All measurements were repeated at least 5 times in independent experiments.
[3H]P1075 (specific activity 1 16 Ci mmol'1) was purchased from Amersham Buchler (Braunschweig, Germany). [3H]glibenclamide (specific activity 51 Ci mmol'1) was obtained from NEN (Dreieich, Germany). If suitable, stock solutions were prepared in dimethylsulfoxide with a final solvent concentration in the media below 1 %.
SUR- or Kirδ.x isoforms were used either subcloned in the pcDNA (hamster
SUR1 , mouse Kir6.2) or pCMV vector (rat SUR2A, SUR2B).
Rodent SUR-isoforms and KATP channels were transiently expressed in COS-1 cells as described (see Schwanstecher et al., 1998); Dόrschner et al., 1999); Uhde I. et al. J Biol Chem 274 (1999) 28079-28082; Gross I. et al. MoI. Pharmacol. 56 (1999) 1370-1373; Markworth E., Diabetes 49 (2000) 1413-1418). A mutated form of the SUR2 isoforms with the phenylalanine residue in position 1205 substituted with a serine (SUR2Y1205s) was used to allow detection of binding to the sulfonylurea site of these isoforms by displacement of [3H]glibenclamide (Uhde I., Dissertation 2001 ). Briefly, COS-1 cells cultured in DMEM HG (10 mM glucose), supplemented with 10 % fetal calf serum (FCS), were plated at a density of 5 x 105 cells per dish (94 mm) and allowed to attach overnight. For transfection the cells were incubated 4 hours in a Tris- buffered salt solution containing DNA (5 - 10 μg/ml) plus DEAE-dextran (1 mg/ml), 2 min in HEPES-buffered salt solution plus dimethylsulfoxide (10 %) and 4 hours in DMEM-HG plus chloroquine (100 μM). Cells were then returned to DMEM-HG plus 10 % FCS. Membranes were prepared 60-72 h post transfection as described (Schwanstecher M. et al., Br. J. Pharmacol. K)6 (1992) 295-301 (= Schwanstecher et al., 1992)). For binding experiments resuspended membranes (final protein concentration 5 - 50 μg/ml) were incubated in "Tris-buffer" (50 mM, pH 7.4) containing either [3H]glibenclamide (final concentration 0.3 nM or 3 nM and nonspecific binding defined by 100 nM or 1 μM glibenclamide for SUR1 or SUR2Y12o5s-isoforms, respectively) or [3H]PI 075 (final concentration 3 nM, nonspecific binding defined by 100 μM pinacidil) and increasing concentrations of the test compounds. The free Mg2+ concentration were kept close to 0.7 mM. ATP (0.1 mM) was added to incubation media to enable KCO (e.g. diazoxide, [3H]PI 075) binding (see Schwanstecher et al., 1998). Incubations were carried out for 1 h at room temperature and were terminated by rapid filtration through Whatman GF/B filters.
The inhibition constant (Ki value) of the test substances was calculated from the respective IC50 value, and was stated as the negative logarithmic value thereof (pK).
2. In vitro binding affinity of the test compounds to CB1 receptors
The affinity of the compounds of the invention for cannabinoid CB1 receptors can be determined using membrane preparations of Chinese hamster ovary (CHO) cells in which the human cannabinoid CB1 receptor is stably transfected in conjunction with [3H]CP-55,940 as radioligand. After incubation of a freshly prepared cell membrane preparation with the [3H]-ligand, with or without addition of compounds of the invention, separation of bound and free ligand is performed by filtration over glassfiber filters. Radioactivity on the filter is measured by liquid scintillation counting.

Animals: Male Wistar rats in the weight range 175-200 g were group housed in standard animal cages at a temperature of 21 ±2°C and humidity of 55±10%. Animals were maintained on a 12 h light-dark cycle (lights on 06.00-18.00 h) with free access to standard rodent diet (B&K Universal Ltd standard rat and mouse diet (BK 001 P), Beekay Feeds, B&K Universal Ltd, Hull, East Riding of Yorkshire) and tap water. The rats were accustomed to these conditions for at least one week before experimentation.
Experimental procedures: After the rats were sacrificed, the branch of the bile duct leading to the liver and the duodenal end of the duct in the pancreas were clamped and the pancreas distended by injection of ice-cold 0.9 mg/ml collagenase solution into the bile duct. The pancreas were then removed and incubated statically for 10-12 min at 37°C. Following the incubation, 10 ml of cold buffer was added and the suspension shaken vigorously by hand for 1 min. The islets were allowed to settle for 5 min on ice and washed three times using ice-cold buffer. Well formed and good sized islets from 3 rats were hand-picked (under a low power microscope) and pooled and a final selection of islet transferred to the perifusion apparatus. Oxygenated (95%
O2/5% CO2) Gey & Gey buffer containing 1 mg/ml bovine serum albumin and 4mM glucose were used throughout the experiment unless otherwise stated (see Dickinson et al. Eur. J. Pharmacol. 1997; 339: 69-76 for further details).
Compounds were either tested at an advised concentration or the solubility was determined in the experimental conditions and a maximum soluble drug concentration used for experiments (DMSO or ethanol will be used as the solvents at a maximum 0.1 % in the assay buffer).
Two experiments were performed in parallel in two identical, independent sets of perifusion apparatus each consisting of sufficient number of chambers. Each chamber was loaded with 20 hand-picked islets. Islets were perifused for an initial 30 min period in media containing 4 mM glucose. Perifusate was then collected at 2 min intervals for the remainder of the experiment. After the first 10 min of the experiment (to collect baseline insulin values), the media in each chamber was switched to one containing 1 1 mM glucose and the relevant drug concentration/vehicle/diazoxide concentration and perifusate collected for a further 62 min to produce a total of 36 fractions for each chamber. Perifusate samples were then pooled to create three samples per chamber as follows: Baseline (4mM): Samples 1-5 (first 10 minutes); 0-30 minutes (1 1 mM glucose): Samples 6-21 ; 30-60 minutes (1 1 mM glucose): Samples 22-36. Perifusate fractions were stored at -75°C until required for insulin assay. Insulin content of fractions were assayed using a 96-well ELISA assay (Mercodia). Initial insulin assays were performed in triplicate on three pooled fractions from each chamber.
Drugs: All chemicals were obtained from Sigma (or other appropriate commercial supplier).
Result: The three islet preparations showed a consistent degree of glucose dependent insulin secretion. The mean insulin secretion at 1 1 mM glucose was 98.3 ± 12.6 pg/islet/min and 130.4 ± 22.0 pg/islet/min at 0-30 and 30-60 minutes, respectively. In the presence of 4 mM glucose this was significantly lower and was 3.8 ± 0.6 pg/islet/min and 3.4 ± 0.1 pg/islet/min at 0-30 and 30-60 minutes, respectively. Thus, insulin secretion was increased by 26 times and 38 times by 11 mM glucose at 0-30 and 30-60 minutes, respectively. Data were initially expressed as a simple mean of the three experiments for insulin secretion (pg/islet/min) and multiple t-tests (against the corresponding vehicle time period) used to determine potential significant effects of treatments. Alternatively, data were also calculated as a % vehicle effect for each experimental day. This latter approach was deemed to be the more powerful analysis as it corrected for the day to day variation in insulin release from the islets. Diazoxide significantly inhibited insulin secretion by an average of 55.3% (0-30 min) and 58.9% (30-60 min).
