A total of 25 targeted hydrogen sulfide donor–pentacyclic triterpene hybrids were designed, synthesized and evaluated on the basis of inspiring reports about hydrogen sulfide donor molecules and oleanolic acid derivatives on anti-tumor activity. The results revealed that only some hybrids (10a, 10b, 12a, 12b, 13a, and 15b) showed moderate anti-proliferation activity against K562 cell line. It indicated that oleanane-type, (R)-lipoic acid and TBZ groups were much more favorable to the anti-proliferation activity. Furthermore, C-3 OH was more beneficial than C-28/29 COOH in the oleanane-type to the antitumor activity of the batch of (R)-lipoic acid derivatives. And among them, only compound 13a exhibited moderate anti-proliferation activity against both K562 and K562/ADR cell lines, while it exhibited no anti-proliferation activity against BEL-7402 and L-O2 cell lines. Therefore, it suggested that it was not suitable for hybridization of hydrogen sulfide donors attached to oleanolic acid, ursolic acid and glycyrrhetinic acid in the field of anti-tumor.
