Structure–activity relationships of 3-substituted N-benzhydryl-nortropane analogs as nociceptin receptor ligands for the treatment of cough
摘要:
A series of 3-axial-aminomethyl-N-benzhydryl-nortropane analogs have been synthesized and identified to bind to the nociceptin receptor with high affinity. Many of these analogs showed high binding selectivity over classic opioid receptors such as l receptor. The synthesis and structure-activity relationships around the C-3 nortropane substitution are described. Selected compounds with potent oral antitussive activity in the guinea pig model are disclosed. (C) 2008 Elsevier Ltd. All rights reserved.
Identification of 3-substituted N-benzhydryl-nortropane analogs as nociceptin receptor ligands for the management of cough and anxiety
摘要:
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. (c) 2009 Elsevier Ltd.
