Artesunate is an inhibitor of bothSTAT-3andexported protein 1(EXP1).

Artesunate is an inhibitor of both STAT-3^[1]and exported protein 1 (EXP1)^[2]. Artesunate treatment for 24 h causes a significant increase in the levels of reactive oxygen species (ROS) in a dose-dependent manner in both cell lines. Moreover, Western blotting shows that the levels ofγ-H2AX are significantly elevated when cancer cells are treated with Artesunate in the higher dose range for 24 h. Artesunate also shows a time-dependent effect on the level of RAD51 in A2780 and HO8910 cells. In two types of non-malignant cells, normal human fibroblasts and immortalized epithelial cells, FTE-187, the level of RAD51 is not altered by Artesunate. In A2780 cells, the level of RAD51 mRNA is indeed decreased by the addition of Artesunate, in a dose-dependent manner. Correspondingly, the promoter activity of RAD51 is significantly inhibited by Artesunate. In contrast, the RAD51 mRNA level in H8910 cells is not affected by Artesunate^[3].

Tumor growth is significantly reduced in the group receiving combined treatment of Artesunate and cisplatin (P<0.01). In comparison, Artesunate alone has no significant effect on the growth of tumor xenografts for both cell lines^[3].
