identified from previous studies and molecular docking interactions, thiazolidine-2,4-dionederivatives have been evaluated for their PARP inhibitory activity. From an in vitro assay, 5-((1-(4-isopropylbenzyl)-1H-indol-3-yl)methylene)thiazolidine-2,4-dione (16) was identified as a potent inhibitor having low micromolar inhibitory activity \((\hbox IC}_50} \,=}\, 0.74 \,\pm \, 0.25\,\upmu \hbox M})\)
