The synthesis and SAR of a novel 3-benzazepine series of 5-HT2C agonists 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 [3H]phosphoinositol turnover: 5-HT 2C = 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 at 6 h = 18 mg/kg). Lorcaserin was further characterized in a single-dose pharmacokinetic study in rat (t1/2 = 3.7 h; F = 86%) and a 28-day model of weight gain in growing Sprague-Dawley rat (8.5% decrease in weight gain observed at 36 mg/kg b.i.d.). Lorcaserin was selected for further evaluation in clinical trials for the treatment of obesity.

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 [3H] 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-HT 2C receptor agonists, which decrease food intake in a rat feeding model.

The present invention relates to certain 1-substituted-2,3,4,5-tetrahydro-3-benzazepine derivatives of Formula (I), that are modulators of the 5HT2C receptor. Accordingly, compounds of the present invention are useful for the prophylaxis or treatment of 5HT2C receptor associated diseases, conditions or disorders, such as, obesity and related disorders.
