A series of [2-(ω-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. It particular, [2-(4-phenylbutyl)phenoxy]-methylpiperidine derivatives, 10b, 10i and 10q, exhbited potent inhibition. The structure-activity relationships in this series of compounds are discussed.
