title: 7-Sulfonamido-3-benzazepines as potent and selective 5-HT2C receptor agonists: hit-to-lead optimization.
abstract: New 7-sulfonamido-3-benzazepines 3 are disclosed as 5-HT(2C) receptor agonists. Appropriate substitution of the amino group (R(1)R(2)N-) gave compounds that were potent 5-HT(2C) agonists with minimal activation of the 5-HT(2A) and 5-HT(2B) receptors. Furthermore, representative examples had excellent in vitro ADME properties and good selectivity over ion channel activity.
