摘要：For the first time, a series of highly potent natural product inspired substituted (Z)-3-benzylideneisobenzofuran-1(3H)-ones 28a-t, embraced with electron-withdrawing groups (EWG) and electron-donating groups (EDG) at site I and site II, were prepared and assessed for their in vitro antioxidant activities (DPPH free radical scavenging assay) and arachidonic acid (AA)-induced antiplatelet activities using ascorbic acid (IC50 = 4.57 µg/mL) and aspirin (IC50 = 21.34 µg/mL), as standard references, respectively. In this study, compounds 28f-g, 28k-l and 28q have shown high order of in vitro antioxidant activity. Infact, 28f and 28k were found to show 10-folds and 8-folds more antioxidant activity than ascorbic acid, respectively and was found to be the most active analogues of the series. Similarly, Compounds 28c-g, 28k-l, 28o and 28q-t were recognized as highly potent antiplatelet agents (upto 6-folds) than aspirin. Furthermore, in silico studies of the most active antioxidants 28f, 28k and 28l and very active antiplatelet molecules 28f, 28k, 28l and 28s were carrying out for the validation of the biological results. This is the first detailed study of the discovery of several (Z)-3-benzylideneisobenzofuran-1(3H)-ones as highly potent antioxidants and antiplatelet agents.
