BioAssay: AID 719288

Antagonist activity at human kappa opioid receptor expressed in CHO cells assessed as inhibition of U50,488-induced [35S]GTPgammaS binding after 60 mins by scintillation counting

N-[2-(4'-methoxy[1,1'-biphenyl]-4-yl)ethyl]-8-CAC (1) is a high affinity (K(i)=0.084 nM) ligand for the mu opioid receptor and served as the lead compound for this study. Analogues of 1 were made in hopes of identifying an SAR within a series of oxygenated (distal) phenyl derivatives. A number of new analogues were made having single-digit pM affinity for the mu receptor. The most potent was the 3',4'-methylenedioxy analogue 18 (K(i)=1.6 pM). ..more
