Ten Tyr-D-Arg-Phe-betaAla-NH(2) (YRFB) analogs in which specific amino acid side chains are shifted to the N(alpha)-position were synthesized, and the binding to these analogs to the mu receptor and their in vitro biological properties were evaluated. Some analogs in which a N,N-bis(p-hydroxybenzyl)-Gly residue was substituted for Tyr(1) exhibited mu receptor antagonist activities (pA(2)) between 5.3 and 6.1. Of these analogs, [N,N-bis(p-hydroxybenzyl)-Gly(1)]YRFB was found to be the most potent specific antagonist for the mu-opioid receptor.
