title: Synthesis of a novel 6,14-epoxymorphinan derivative and its pharmacology.
abstract: A novel 6,14-epoxymorphinan benzamide derivative (NS22) was synthesized, which showed opioid kappa receptor agonistic activity in the [(35)S]GTPgammaS binding assay. The antinociceptive effect of NS22 was evaluated in the tail-flick and the hot-plate test. This compound showed a potent antinociceptive activity in mice by s.c. administration, which was attenuated with nor-BNI (selective opioid kappa receptor antagonist).
