Abstract

A novel series of N α-imidazolylalkyl and pyridylalkyl derivatives of histaprodifen (6, 2-[2-(3, 3-diphenylpropyl) imidazol-4-yl] ethanamine) was synthesized and evaluated as histamine H1-receptor agonists. The title compounds displayed partial agonism at contractile H1- receptors of guinea pig ileum and were at least equipotent with histamine. Agonist effects of the new derivatives were susceptible to blockade by the H1-receptor antagonist ...
