Effects of sinensetin on viability of A549 cells. a Chemical structure of sinensetin. b A549 cells (3 × 105 cells/well) were treated with the indicated concentrations of sinensetin (0–800 μg/ml) for 48 h. Then, viability of A549 cells was determined by MTT assays. c Culture medium of A549 cells with the indicated concentrations of sinensetin (0–800 μg/ml) incubation for 48 h was collected and LDH activity was analyzed. Results are expressed as mean ± SEM. *P < 0.05 compared to untreated group
