Abstract

A series of new hydroxamate derivatives of lupane triterpenoids has been designed and successfully synthesized. The synthesized compounds were evaluated for their in vitro antitumor activity using the 3-[4,5-dimethylthiazol-2-yl]−2,5-diphenyltetrazolium bromide-based assay against the human cancer cell lines KB and HepG2. Most of these derivatives possess at least moderate cytotoxic activity and the hydroxamate derivative compounds 3c, 3e, 7a, and 15b could be lead compounds for further optimization to develop novel anticancer agents.
