Starting from oleanolic acid (OA), the target compounds (10a-10i) were synthesized via introducting α,β-unsaturated ketone moiety to OA by 7-step successive reactions including benzylation, acetylation, oxidization, bromine substitution-elimination, etc., followed by coupling of C28-carboxyl with substituted furoxans via a glycine linker. All the target compounds were identified by IR, MS and 1H NMR. MTT assay results showed that compounds 10a-10i displayed much stronger inhibitory effects than OA on the proliferation of four human tumor cell lines. The anti-proliferative activity of 10a-10e and 10i against human hepatoma HepG2 cell was comparable to that of the positive control 2-cyano-3, 12-dioxooleana-1,9(11)-dien-28-oic acid methyl ester (CDDO-Me).
