Table 1 Comparison between cisplatin and cisplatin@CB[7] toxicty by MTT assay. The in vitro cytotoxicity of cisplatin and cisplatin@CB[7] in the human ovarian cancer cell line A2780 and its cisplatin-resistant cell line A2780-Rab25. IC50 is defined as the concentration of drug required to inhibition of cell growth by 50 % ovarian cancer cell line A2780 and its cisplatin-resistant cell line A2780-Rab25. IC50 is defined as the concentration of drug required to inhibition of cell growth by 50 %
