A series of 3-phenylcoumarins were synthesized and screened for potential antidepressant activity by tail suspension test (TST) in mice. Three compounds (6, 7 and 13) exhibited impressive antidepressant activity, measured in terms of percentage decrease in immobility duration (% DID). In addition, the active antidepressant compounds were subsequently studied at their most effective dose and activity of these compounds were confirmed in forced swimming test (FST) animal model, in which the compounds at a low dose of 0.5mg/kg significantly decreased the immobility time and exhibited greater efficacy than the reference standards fluoxetine and imipramine. The potent compounds did not show any neurotoxicity in the rotarod test and the preliminary results are promising enough to warrant further studies around this scaffold.
