Epiminocyclohepta[b]indole analogs as 5-HT6 antagonists

A new series of epiminocyclohepta[b]indoles with potent 5-HT6 antagonist activity were discovered and optimized using in vitro protocols. One compound from this series was progressed to advanced pharmacokinetic (PK) studies followed by 5-HT6 receptor occupancy studies. The compound was found to have excellent oral absorption, a highly favorable PK profile and demonstrated pharmacodynamic interaction with the 5-HT6 receptor as shown by ex vivo autoradiography.

The synthesis and SAR of epiminocyclohepta[b]indole analogs as 5-HT6 antagonists are described.Figure optionsDownload as PowerPoint slide
