dc.description.abstractPiperazine derivatives have been of great interest to medicinal chemists in the development of antidepressant drugs due to their distinct molecular and structural features along with their pharmacological profile. In this study, we have designed and synthesized a series of 10 compounds of piperazine clubbed oxadiazole derivatives (5a-j) and screened for their MAO inhibitory activity. Compound 5f and 5 g were found to be the most potent MAO-A inhibitors of the series with IC50 values of 0.96 ± 0.04 µM µM and 0.81 ± 0.03 µM, respectively with a selectivity index of 18-folds and 9-folds over MAO-B isoform. The compounds were found to be reversible in hibitors of MAO-A with no cytotoxicity against SH-SY5Y neuronal cells. The compounds also displayed good antioxidant activity. Further, in vivo TST studies revealed that both the compounds 5f and 5 g possessed good anti-depressant-like activity and reduced the immobility time significantly although were found inactive in FST studies. The molecular docking studies revealed that both compounds fit well at the active site of MAO-A enzyme as similar to clorgyline and form a stable complex. The results were confirmed via molecular dynamic studies which demonstrate the stable complex formation between MAO-A and 5f & 5 g. The appropriate drug-like characteristics with favourable ADMET profile, these molecules presented this piperazine clubbed oxadiazole structural framework as a key pharmacophore for the development of new antidepressant molecules along with strong candidature for further clinical investigations.en_US
