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.
