N-Phenethylnormorphine is an opioid analgesic drug derived from morphine by replacing the N-methyl group with β-phenethyl.[1] It is around eight to fourteen times more potent than morphine as a result of this modification,[2] in contrast to most other N-substituted derivatives of morphine, which are substantially less active, or act as antagonists.[3] Binding studies have helped to explain the increased potency of N-phenethylnormorphine, showing that the phenethyl group extends out to reach an additional binding point deeper inside the mu opioid receptor cleft, analogous to the binding of the phenethyl group on fentanyl.[4][5]
