Abstract

NI-Alkylation of 1H-benzimidizole of the delta agonist H-Dmt-Tic-NH-CH2-Bid with hydrophobic, aromatic, olefinic, acid, ethyl ester, or amide (1-6) became delta antagonists (pA(2) = 8.52-10.14). delta- and mu-Opioid receptor affinities were high (K-i delta = 0.12-0.36 nM and K-i mu = 0.44-1.42 nM). Only delta antagonism (pA(2) = 8.52-10.14) was observed; mu agonism (IC50 = 30-450 nM) was not correlated with changes in alkylating agent or delta antagonism, and some compounds yielded mixed delta antagonism/gamma agonism.
