Artemisinin reduced the increase of H₂O₂-induced oxidative stress in D407 cells. After pre-treatment with 30 μM Artemisinin or 0.1% DMSO (vehicle control) for 2 h, D407 cells were incubated with or without 100 μM H₂O₂ for another 24 h. Intracellular ROS level was determined by the CellROX® Deep Red Reagent. ^###P<0.005 versus control group;***P<0.005 versus H₂O₂-treated group was considered significantly different.
