Abstract:

A novel series of first procaspase activating compound(PAC-1) analogues was designed, synthesized and evaluated for antitumor activity towards two cell lines[human promyelocytic leukemia cell line(HL60) and human embryonic lung fibroblast cell line(HLF)] by the MTT[3-(4,5)-dimethylthiahiazo(-z-y1)-3,5-di-phenytetrazo-liumromide] method in vitro. The structures of all the compounds were confirmed by 1H NMR, MS and elemental analysis. Among the compounds synthesized,(E)-2-[(3-{[4-(tert-butyl)benzyl](methyl)amino}propyl)(methyl)amino]-N'-[4-(diethylamino)-2-hydroxybenzylidene]acetohydrazide(compound 6n) exhibits a good anti-proliferative activity to the majority of tumor cells tested, and selectively cleaves cancer cells. Thus, compound 6n was identified as promising lead compound for further structural modification.
