(+/-)-N-Methyl-N-[trans-2-(1-pyrrolidinyl)cyclohexyl]-1-phenylcyclopropanecarboxylic amide (1) and its dichloro analog (2) were synthesized. Compounds 1 and 2 are related to the kappa-selective opiate U-50488 in that the benzylic methylene moiety in U-50488 has been replaced by a cyclopropane ring. As compared to U-50488, a 600-fold reduction in kappa-affinity was observed with these 2 compounds; while the reduction in mu-affinity was less than 2-fold. Unlike U-50488, 1 and 2 also show measurable sigma-binding. To explain the observed anomaly, the steric interaction between the N-methyl group and the cyclopropane ring and the tendency of the cyclopropane ring to conjugate with the neighboring phenyl group, both affecting the accessible conformations of the amide side chains of 1 and 2, are considered important factors.

This paper describes the synthesis and kappa and mu opioid receptor binding affinity of some conformationally restrained derivatives of the arylacetamide group in the selective kappa opioid receptor agonist (+/-)-trans-N-methyl-N-[2-(1-pyrrolidinyl) cyclohexyl]benzo [b]thiophene-4-acetamide monohydrochloride (1,PD117302), which is an analogue of U-50, 488. The methyl-substituted derivatives (+/-)-trans-N

chemical synthesis and the development of structure-activity relationships (SAR) for the kappa opioid receptor affinity and mu/kappa opioid receptor selectivity of novel N-[(2-aminocyclohexyl)aryl]acetamide derivatives. The SAR of this series are investigated by consideration of structural modifications made to the aromatic moiety, the amide linkage, and cyclohexane and the pyrrolidine ring substituents
