The present invention concerns compounds of general formula (I) characterized in that (formula 1) wherein, in particular: —R
1
represents one or more groups such as: trifluoromethyl, halogen such as F, Cl, —when n=m=1, W represents CH then Y represents oxygen, —U represents: either —(C═O)CH
2
NH— and is branched at position 4 of pyridazinone, then R2 represents H, or —(C═O)NH— and U is branched at positions (4), (5) or (6) of pyridazinone, then R2 represents H, —R3 represents a hydrogen or methyl and the addition salts with pharmaceutically acceptable bases and acids and the different isomers, and their mixtures in any proportion for use as SCD-1 enzyme inhibitors for the treatment of obesity, type-2 diabetes and lipid disorders.
本发明涉及一般式(I)的化合物,其特征在于(公式1),其中特别地:
- R1表示三氟甲基、卤素(如F、Cl)等一个或多个基团;
- 当n=m=1时,W表示CH,Y表示氧;
- U表示:要么是(C═O)CH2NH,且在吡嗪酮的位置4处分支,此时R2表示H;要么是(C═O)NH,且U在吡嗪酮的位置(4)、(5)或(6)处分支,此时R2表示H;
- R3表示氢或甲基;
- 以及它们与药用可接受的酸和碱形成的加合物和不同的异构体,以及它们在任意比例下混合,作为SCD-1酶抑制剂,用于治疗肥胖症、2型糖尿病和脂质代谢紊乱。
