4,5-Dihydro-3-methylbenzo[1,2-b]furan-4,5-dione(4) was identified as a novel and potent inhibitor of caspase-3 through structural modification of an existing drug, sodium tanshinone IIA sulfonate(STS). Compound 4 ...4,5-Dihydro-3-methylbenzo[1,2-b]furan-4,5-dione(4) was identified as a novel and potent inhibitor of caspase-3 through structural modification of an existing drug, sodium tanshinone IIA sulfonate(STS). Compound 4 showed high potency against caspase-3 in vitro(ICso=0. 13μmol/L). Molecular docking study further provided an insight into the interaction of compound 4 with activated caspase-3. Hence, this small-molecule caspase-3 inhibitor could be a oromising theraoeutic candidate against diseases caused by abnormally up-regulated apptosis.展开更多
