Abstract
Current research aimed at evaluating the in vitro as well as in vivo anticancer activities of a newly synthesized peptide hydrazide; i.e. 4,14-diisopropyl-2,5,13,16-tetraoxo-3,6,12,15-tetraaza-1(3,5)-pyridinacyclohexadecaphane-7-carbohydrazide. The hydrazide was synthesized from methyl 4,14-diisopropyl-2,5,13,16-tetraoxo-3,6,12,15-tetraaza-1(3,5)-pyridinacyclohexadecaphane-7-carboxylate 2 by acting of hydrazine hydrate. It showed significant anticancer effects against different tested cell lines, where cervical, breast, liver, colon, prostate, brain, fibrosarcoma, leukemia and melanoma cell lines were the most affected cell types. The prepared derivative also inhibited VEGF-2 kinase enzyme significantly and exhibited an in vivo tumorigenic effects in mice model.
