3-Azabicyclo[3.1.0] hexane compounds were designed as novel achiral mu opioid receptor ligands for the treatment of pruritus in dogs. In this paper, we describe the SAR of this class of opioid ligand, highlighting changes to the lead structure which led to compounds having picomolar binding affinity, selective for the mu receptor over delta and kappa subtypes. Some subtleties of functional activity will also be described. (C) 2012 Elsevier Ltd. All rights reserved.
