A series of arylalkanol and aralkyl piperazine derivatives have been synthesized and evaluated for 5-HT reuptake inhibitory abilities and binding affinities at the 5-HT1A/5-HT7 receptors. Antidepressant activities of the compounds in vivo were screened using the forced swimming test (FST). The results indicated that the compound 8j exhibited high affinities for the 5-HT1A/5-HT7 receptors (5-HT1A, ki = 0.84 nM; 5-HT7, ki = 12 nM) coupling with moderate 5-HT reuptake inhibitory activity (RUI, IC50 = 100 nM) and showed a marked antidepressant-like activity in the FST model.
