Identification of 3-substituted N-benzhydryl-nortropane analogs as nociceptin receptor ligands for the management of cough and anxiety

Bioorg Med Chem Lett. 2009 May 1;19(9):2482-6. doi: 10.1016/j.bmcl.2009.03.057. Epub 2009 Mar 18.

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.
