Discovery and SAR of new benzazepines as potent and selective 5-HT2C receptor agonists for the treatment of obesity
摘要:
We report on the synthesis, biological evaluation and structure-activity relationships for a series of 3-benzazepine derivatives as 5-HT2C receptor agonists. The compounds were evaluated in functional assays measuring [H-3] phosphoinositol turnover in HEK-293 cells transiently transfected with h5-HT2C, h5-HT2A or h5-HT2B receptors. Several compounds are shown to be potent and selective 5-HT2C receptor agonists, which decrease food intake in a rat feeding model. (c) 2005 Elsevier Ltd. All rights reserved.

The synthesis and SAR of a novel 3-benzazepine series of 5-HT2Cagonists is described. Compound 7d (lorcaserin, APD356) was identified as one of the more potent and selective compounds in vitro (pEC50 values in functional assays measuring [(3)H]phosphoinositol turnover: 5-HT2C = 8.1; 5-HT2A = 6.8; 5-HT2B = 6.1) and was potent in an acute in vivo rat food intake model upon oral administration (ED50
