    In our search for novel small molecules activating procaspase-3, we have designed and synthesized two series of novel (E)-N'-arylidene-2-(2-oxoindolin-1-yl)acetohydrazides (4) and (Z)-2-(5-substituted-2-oxoindolin-1-yl)-N'-(2-oxoindolin-3-ylidene)acetohydrazides (5). Cytotoxic evaluation revealed that the compounds showed notable cytotoxicity toward three human cancer cell lines: colon cancer SW620, prostate cancer PC-3, and lung cancer NCI-H23. Especially, six compounds, including 4f–h and 4n–p, exhibited cytotoxicity equal or superior to positive control PAC-1, the first procaspase-3 activating compound. The most potent compound 4o was three- to five-fold more cytotoxic than PAC-1 i...

    In our continuing search for novel small‐molecule anticancer agents, we designedand synthesized a series of novel (E)‐N'‐(3‐allyl‐2‐hydroxy)benzylidene‐2‐(4‐oxoquinazolin‐3(4H)‐yl)acetohydrazides (5), focusing on the modification of sub-stitution in the quinazolin‐4(3H)‐one moiety. The biological evaluation showed thatall 13 designed and synthesized compounds displayed significant cytotoxicity againstthree human cancer cell lines (SW620, colon cancer; PC‐3, prostate cancer; NCI‐H23, lung cancer). The most potent compound5ldisplayed cytotoxicity up to 213‐fold more potent than 5‐fluorouracil and 87‐fold more potent than PAC‐1, the firstprocaspase‐activating compound. Structure–activi...
