Embodiments of the instant disclosure relate to novel methods and compositions for treating tumors resistant to platinum-based chemotherapy. In certain embodiments, methods of treating tumors herein can include administering an effective amount of at least one ursolic acid derivative. In certain embodiments, methods of treating tumors herein can include administering an effective amount of at least one ursolic acid derivative in combination with at least one platinum-based chemotherapeutic separately or in a combination therapy. In some embodiments, methods of treating tumors disclosed herein can include screening and/or selecting a subject suitable for treatment on the basis of SENP1 tumor expression. In other embodiments, methods of treating tumors can include administering a composition disclosed herein to a subject, the composition having a combination of at least one ursolic acid derivative and at least one platinum-based chemotherapeutic.

specific isopeptidase to catalyze deSUMOylation modification. Inhibiting SENP1 upregulates cancer cell radiosensitivity and it becomes a promising target for radiosensitization. Herein, based on the structure of ursolic acid (UA), a total of 53 pentacyclic triterpene derivatives were designed and synthesized as SENP1 inhibitors. Ten derivatives exhibited better SENP1 inhibitory activities than UA and the

Nineteen ursolic acid derivatives (15 novel compounds) modified at the C-3 and the C-28 positions were synthesized. The cytotoxic activity of the derivatives was evaluated against HeLa, BGC-823 and SKOV3 cells by MTT assay. Inducing apoptosis and affecting cell cycle distribution by the derivatives in HeLa cells were assessed by flow cytometry and DNA fragmentation. Compounds 10b and 11b were particularly
