Abstract

A series of new combretastatin urea derivatives (12a-j) were synthesized by reacting of substituted aromatic isocyanates (11a-j) to the combretastatin pyrazole-amine. The synthesized derivatives 11a-j were evaluated for their cytotoxicity against four human cancer cell lines (breast, lung and ovarian). Among them, compounds 12a, 12c, 12d, 12f, 12g and 12i were showed potent anticancer activity.
