Introduction: Mangiferin inhibits NF-kB, which is constitutively activated in cancer and is induced in response to chemotherapy and radiotherapy. Agent inhibitors of NFκB function might be considered as an adjuvant approach in combination with chemotherapy. Objective: To evaluate the chemosensitizer adjuvant effect in vitro of mangiferin in cotreatments with antineoplastic platinum and 5-fluorouracil. Methods: Mangiferin (1-200 μg/mL) was used in simple and combination (sequential and simultaneous) cotreatments of cisplatin, oxaliplatin and 5-fluorouracil at different times and at non cytotoxic concentrations in CT26.WT cells. The cell survival was evaluated by MTT assay. Results: In cytostatic simple cotreatments, the highest significant increases of cell death were obtained at lowest concentration of cytostatic (cisplatin 1 µM, 5-fluorouracil 0.1 µM). The best results were obtained in sequential cotreatment for cisplatin and in simultaneous cotreatment for 5-fluorouracil. Mangiferin not increase oxaliplatin-induced cell death. In cytostatic combination treatments with cisplatin/5-fluorouracil at low concentrations (1/0.1 µM) increased cell death was independent of the treatment sequence, instead at high concentrations (5/0.5 µM) there was a dependence on treatment schedule. The best results were obtained in the sequential combination at low concentrations. When mangiferin was combinated with oxaliplatin/5-fluorouracil the best result of all series of experiments was obtained by simultaneous cotreatment at low concentrations of cytostatic (1/0.1 µM) and high concentrations of mangiferin (100/200 µg/mL). Conclusions: Mangiferin in combination treatment both in simple and simultaneous cotreatments of cytostatic platinum with 5-fluorouracil potentiates cytostatic-induced cell death in our experimental conditions.
