In this study, a novel series of coumarin piperazine analogues were synthesized using Click chemistry approach. Thus synthesized compounds (8a-j) were evaluated for their pharmacological potentialities. These compounds subjected for evaluation of their anti-tubercular, anti-cancer, anti-inflammatory, and antioxidant properties. Results revealed that analogues 8b, 8d, 8i and 8h are found to be the promising drug-like candidates against Mycobacterium tuberculosis H37Rv strain exhibiting more potent activity than isoniazid with MIC of 2.24, 1.04, 3.72, 5.35 µM respectively. Furthermore, the compound 8d displayed better anti-inflammatory and antioxidant activity with IC50 values of 66.43 µM and 69.14 µM respectively. Molecular docking studies insights into the binding affinities and interactions with a target protein. The in silico ADME profiles supported their pharmacokinetic viability. Predominantly, compound 8d exhibited anticancer activity with IC50 values of 12.42 µM and 26.16 µM with reference to HeLa and MCF-7respectively by inhibiting acetyl-CoA synthetase. These findings highlight more specifically the compound 8d as a potent anti-cancer agent.
