Abstract

A series of nortropane analogs based on previously reported compound 1 have been synthesized and shown to bind to the nociceptin receptor with high affinity. The synthesis and structure-activity relationships around the C-3 nortropane substitution are described. From the SAR study and hPXR screening effort, compound 15 was identified to possess potent oral antitussive and anxiolytic-like activities in the guinea pig models.
