A series of novel aralkyl piperazine derivatives were synthesized, and evaluated for their serotonin reuptake inhibitory and 5-HT1A/5-HT7 receptors affinities activity. Antidepressant activities in vivo of the compounds were screened using the forced swimming test (FST) and tail suspension test (TST). The results indicated that compounds 21k (RUI, IC50 = 31 nM; 5-HT1A, 5-HT7, ki = 62, 12 nM) and 21n (RUI, IC50 = 25 nM; 5-HT1A, 5-HT7, ki = 28, 3.3 nM) exhibited high affinities for the 5-HT1A/5-HT7 receptors coupled with potent serotonin reuptake inhibition. Specifically, the most promising compound 21n possessed a good oral pharmacokinetic properties and an acceptable hERG profile, and showed potent antidepressant-like effect in the FST and TST models.
