Dihydroartemisinin (DHA) inhibits cell viability of human ovarian cancer cell lines (SKOV3, SKOV3‐IP, HO8910, and HO8910‐PM). Cells were treated with 5‐160 μM DHA, and controls were treated with DMSO. Cell viability was assessed using CCK8 assay after treatment with different doses of DHA or DMSO for 24, 48, and 72 h. Data are expressed as the mean ± SEM of three independent experiments. *P < 0.05, **P < 0.01 and ***P < 0.001, compared to controls
