BACKGROUND: Cisplatin (cis-diaminedichloroplatinum, CDDP) is a widely used chemotherapeutic agent for the treatment of many cancers. However, initial resistance to CDDP is a serious problem in treating these cancers. Vitis coignetiae Pulliat (Meoru in Korea) have shown anti-nuclear factor kappa B and anti-epidermal growth factor receptor activities in cancer cells.

METHODS: In this study, in order to seeking an approach to increase the anti-cancer effects of CDDP with natural products. Here, we investigated anthocyanins isolated from Vitis coignetiae Pulliat (anthocyanidins isolated from meoru, AIMs) can enhance anti-cancer effects of cisplatin (CDDP) in stomach cancer cells. The cell viability of SNU-1 and SNU-16 cells after treated with AIMs and CDDP were analyzed by MTT assay. The expressions of Akt and X-linked inhibitor of apoptosis protein (XIAP) proteins were examined by western blot in AIMs- and CDDP-treated cells.

RESULTS: We found that AIMs enhanced anticancer effects of CDDP, which activity was additive but not synergistic. AIMs suppressed Akt activity of the cancer cells activated by CDDP. AIMs also suppressed in XIAP an anti-apoptotic protein.

CONCLUSIONS: This study suggests that the anthocyanins isolated from fruits of Vitis coignetiae Pulliat enhanced anti-cancer effects of CDDP by inhibiting Akt activity activated by CDDP.
