A series of 2-amino-(5 or 7-substituted-2-oxoindolin-3-ylidene) benzoxazole-5-carbohydrazide derivatives were synthesized by treating 2-aminobenzoxazole-5-carbohydrazide with different substituted isatins. All the synthesized derivatives (VI a-l) were screened for their in vitro anticancer (against HeLa, IMR-32 & MCF-7 cancer cell lines), antioxidant (against DPPH radicals) and antimicrobial activities. The results of these studies showed the dose dependant anticancer, antioxidant and antimicrobial activities of the test compounds and the IC50 values of some compounds were comparable with their standard agent. The test compounds having substitution with different electron withdrawing groups at C-5 position showed more potent anticancer, antioxidant and antibacterial activities than those at C-7 position.
