Redefining the structure-activity relationships of 2,6-methano-3-benzazocines. Part 8. High affinity ligands for opioid receptors in the picomolar Ki range: oxygenated N-(2-[1,1'-biphenyl]-4-ylethyl) analogues of 8-CAC.
2012
Abstract 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 μ 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 μ receptor. The most potent was the 3′,4′-methylenedioxy analogue 18 ( K i = 1.6 pM).
