Description

Diaryl substituted pyrazole derivative, Preparation Method And The Use
Technical field
The present invention relates to the novel diaryl substituted pyrazole derivative of a class, Preparation Method And The Use.Cannabined receptor-1 (the Cannabinoid receptor type 1 that the effect of can be used as of this compounds is powerful, CB1) receptor antagonist and/or inverse agonist and CB1 had highly selective, acceptable salt can be used for treatment, prevention or alleviation by the receptor-mediated disease of CB1, as obesity, diabetes, drug dependence, cognitive defect, nervous system disorders, gastrointestinal tract disease and liver cirrhosis on The compounds of this invention and the pharmacology thereof.
Background technology
Obesity is a kind of metabolic trouble of the multifactor complexity that causes, has become the health problem in the whole world.The energy that human body is taken in is greater than the energy generation obesity of human consumption, and it is to HUMAN HEALTH and keep good physical and mental statuse to produce totally unfavorable influence.According to the data of U.S.'s disease control with centre of prevention and cure, about 2/3rds overweight (IC BMI=25.5~29.9kg/m of U.S. adult 2), the fat (BMI 〉=30kg/M of U.S. adult over half 2).The World Health Organization estimates that the whole world has 700,000,000 people overweight at present, and expecting the whole world in 2025 has 300,000,000 people's obesities.The more important thing is that twenty or thirty in the past is in year, overweight and fat children and teenager's number have increased by 1 times.Obesity is the high risk factor that causes diseases such as coronary artery disease, hypertension, hyperlipidemia, diabetes, tumour, cardiovascular and cerebrovascular diseases, sacroiliitis and somnopathy.Only the U.S. annual with overweight and fat relevant death toll just greater than 300,000 [Drugs of Future 2005,30 (2): 128].
Overweight very complicated owing to causing with pathologic, physiologic factor obesity, also there is not the ideal methods of treatment at present, orlistat (Orlistat) and sibutramine (Sibutramine) only can produce medium (2.6~4.8kg) reduction body weight effect.It is Cannabined receptor-1 (CB1) and Cannabined receptor-2 (CB2) that Cannabined receptor (Cannabinoid receptor) has two kinds of hypotypes.The CB1 acceptor in the cerebral hippocampus district, there are high level expression in lamina corticalis, cerebellum, basic nervous center (basal ganglia) and some peripheral tissues as fat, gi tract, lung, reproductive system and cardiovascular systems, the CB2 acceptor is mainly expressed [J.Med.Chem.2004 in immunity system, 47,627].Studies show that CB1 receptor antagonist or inverse agonist (antagonist/inverse agonist) have the potentiality of a series of diseases relevant with the CB1 acceptor of treatment as obesity, diabetes, mental disorder, substance depilatory and gastrointestinal tract disease.As if particularly the CB1 acceptor has participated in the power balance of control human body, body weight balance and award, so the CB1 receptor antagonist can effectively reduce the picked-up of food, lowering blood glucose, withdrawal drug dependence (as smoking).
Existing document and patent [Expert.Opin.Ther.Patents 2002,12 (10), and 1475; IDrugs 2005,8 (1), and 53; Expert.Opin.Ther.Patents 2004,14 (10), and 1435; Current MedicinalChemistry, 2005,12,1361] a series of CB1 receptor antagonists or inverse agonist are disclosed.United States Patent (USP) 5624941 and WO 2006/074445 disclose pyrazole derivatives and to the CB1 receptor antagonist activity, WO 02/076949 discloses a class and has had the chirality 4 of very strong CB1 receptor antagonist activity, 5-pyrazoline derivative, WO 2006/074445 discloses the heterocycle pyrazole analogs of the novel CB1 of the acting on acceptor of a class, and WO 03/077847 discloses the substituted amide compound with CB1 receptor antagonist and/or reverse agonist activity.
Yet these compounds also exist avidity satisfactory inadequately in the prior art, to shortcomings such as the CB1 receptor-selective are lower, so this area presses for new antagonist and/or the inverse agonist that the CB1 acceptor is had highly selective of exploitation.
