dimethylamino team enormously improves the MOR affinity, as in U-47700. By contrast, embedding that very same basic nitrogen into a cyclic pyrrolidine ring greatly boosts the KOR affinity, as in U-50488. MOR/KOR selectivity is influenced with the N-substituted benzamide and a pair of-phenylacetamide number of compounds which was explored by the Upj
