Abstract:
:Chemopreventative phytochemicals having antitumour and antioxidant properties can overcome problems of chemoresistance and nonspecific toxicity towards normal cells that are associated with platinum-based chemotherapy against cancer. These agents exert their effects by bringing into play numerous cellular proteins that in turn affect multiple steps in pathways leading to tumourigenesis. In this study, combinations of two cytotoxic phytochemicals anethole and curcumin were applied in binary combination with platinum drugs cisplatin and oxaliplatin to three epithelial ovarian cancer cell lines: A2780 (parent), A2780(cisR) (cisplatin-resistant) and A2780(ZD0473R) (ZD0473-resistant). Cell viability was quantified using the 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) reduction assay and the combined drug action was analyzed based on the equations derived by Chou and Talalay (1984). Greatest synergism was observed when the phytochemical was added first followed by the platinum drug 2 h later and additiveness to antagonism in combined drug action was observed when the two compounds were administered as a bolus. If confirmed in vivo, the appropriate sequenced combinations of platinum with the phytochemicals may provide a means of overcoming drug resistance.
