Artesunate, a potential drug for treatment of Babesia infection OAK
Goo, Youn-Kyoung; Terkawi, M. Alaa; Jia, Honglin; Aboge, G. Oluga; Ooka, Hideo; Kim, Suk; Igarashi, Ikuo; Nishikawa, Yoshifumi; Xuan, Xuenan.
The effect of artesunate, a water-soluble artemisinin derivative, against Babesia species, such as Babesia bovis, Babesia gibsoni, and Babesia microti was studied. Cultures of B. bovis and B. gibsoni were treated with 0.26 μM, 2.6 μM, 26 μM, and 260 μM artesunate, and the growth-inhibitory effect was shown in over 2.6 μM artesunate in day 4 and day 3 post-subculture for B. bovis and B. gibsoni, respectively, in dose-dependent manner. In vivo experiment for B. microti, strong inhibition effects were observed in mouse groups treated with over 1.0 mg/kg body weight of artesunate on day 9 and 10 post-infection. These results suggest that artesunate could be a potential drug for Babesia infection.

Artesunate promotes Th1 differentiation from CD4+ T cells to enhance cell apoptosis in ovarian cancer via miR-142 BJMBR
Chen,Xiao; Zhang,Xue-ling; Zhang,Guo-hua; Gao,Ying-fang.
The aim of this study was to evaluate the influence of artesunate on Th1 differentiation and its anti-tumor effect on ovarian cancer. A Murine ovarian cancer model was established by ID8 cells transplantation. The expression of miR-142 and Sirt1 proteins in peripheral CD4+ T cells were quantified with qRT-PCR and western blot, respectively. Peripheral CD4+ T cells were induced for Th1 differentiation. The percentages of apoptosis of Th1/CD4+ T cells and ovarian cancer cells were analyzed by flow cytometry. The IFN-γ level was examined through enzyme-linked immunosorbent assay. Artesunate promoted miR-142 expression in peripheral CD4+ T cells and Th1 differentiation from CD4+ T cells. Artesunate promoted cell apoptosis of ovarian cancer cells by inducing...
