Spasmolytic agents. 2. 1,2,3,4-Tetrahydro-2-naphthylamine derivatives

Abstract
N-[(Benzoyloxy)alkyl]-1,2,3,4-tetrahydro-2-naphthylamine derivatives were synthesized from 1,2,3,4-tetrahydro-2-naphthylamines and evaluated for their spasmolytic activity. Some of these compounds showed a nerve-selective effect on colon rather than stomach in anesthetized dogs and were equal to or more active than the reference drug (mebeverine). The biological data have indicated some structure-activity relationships. Among these compounds, N-ethyl-N-[6-[(3,4-dimethoxybenzoyl)oxy]hexyl]-1,2,3,4-tetrahydro-6-methoxy-2-napththylamine hydrochloride (63) was the most active spasmolytic agent.
