Artemisinin concentration- and time-dependently reversed the decrease in cell viability. (A) Chemical structure of ART. (B) The cytotoxicity of ART, cells were treated with ART (3.125-200μM) for 24h and cell viability was measured using the MTT assay. (C) The cytotoxicity of Aβ1-42. Cells were treated with Aβ1-42 (0.5-8μM) for 24h and cell viability was measured using the MTT assay. (D) The effect of ART on cell viability. Cells were incubated with ART at indicated concentrations with or without 4μM Aβ1-42 for another 24h and cell viability was measured using the MTT assay. *P<0.05 or **P<0.01, or ***P<0.001, CTL vs Aβ1-42; #P<0.05 or ##P<0.01 Aβ1-42 vs Aβ1-42+ART.
