Mechanism of Action

Targets/IC₅₀/Ki	EXP1(a membrane glutathione S-transferase) STAT3
In vitro	ART could alter the biomechanical properties of the glioma cells to inhibit cell proliferation, migration and invasion . This compound significantly suppresses the cell proliferation, induces the apoptosis and promoted cell cycle arrest at G0/G1 phase in SKM-1 cells. The mechanisms of its anti-MDS is associated with the increase of intracellular calciumion concentration and ROS levels. In addition, the pro-apoptotic activity of this chemical may be involved in the regulation of BCL-2 /BAX ratio and the expressions of P-bad and survivin. Its treatment demethylates CDH1, which, in turn recovers the E-cadherin activation in SKM-1 cells.
In vivo	Artesunate is a medication used to treat malaria. This compound can induce radiosensitivity of HeLa cells in vivo using Xenograft model of nude mice. It had a relatively high immunosuppressive activity with low toxicity, and could inhibit T lymphocyte proliferation induced by mitogen and alloantigen.
