摘要
An improved synthetic method for triplet drugs with the 1,3,5-trioxazatriquinane skeleton was developed that used p-toluenesulfonylmethyl isocyanide (TosMIC) instead of 1,3-dithiane. Using the improved method, we synthesized compounds with two identical pharmacophore units and an epoxymethano group, that is, capped homotriplets. Among the synthesized capped homotriplets, KNT-123 showed high selectivity for the p receptor over the kappa receptor, and the mu selectivity was the highest among the reported p selective nonpeptide ligands. KNT-123 administered subcutaneously induced a dose-dependent analgesic effect in the acetic acid writhing assay, and its potency was 11-fold more potent than that of morphine. KNT-123 may serve as a useful tool for the study of the pharmacological actions mediated specifically via the mu receptor. (C) 2011 Elsevier Ltd. All rights reserved.
