[2-(omega-phenylalkyl)phenoxy]alkylamines: synthesis and dual dopamine2 (D2) and 5-hydroxytryptamine2 (5-HT2)...

A series of [2-(omega-phenylalkyl)phenoxy]alkylamines was synthesized and their 5-hydroxytryptamine2 (5-HT2) and/or dopamine2 (D2) receptor antagonistic activities were examined in vitro. [2-(4-Phenylbutyl)phenoxy]alkylamines showed strong inhibition of both 5-HT2 and D2 receptors. In particular, [2-(4-Phenylbutyl)phenoxy]-methylpiperidine derivatives, 10b, 10i and 10q, exhibited potent inhibition. The structure-activity relationships in this series of compounds are discussed.
