Effects of ardipusilloside I on the cell viability of human mucoepidermoid carcinoma Mc3 cells. (A) Exponentially growing of MEC1 cells, Mc3 cells and primary cultured parotid acinar cells were treated with various concentrations of ardipusilloside I (0, 2.5, 5.0,7.5, 10.0, and 12.5 μg/ml) for 48 h. (B) MEC1 cells were treated with 5.0, 7.5, 10.0, and 12.5 μg/ml of ardipusilloside I for various times. (C) Exponentially growing Mc3 cells were treated with 10.0 μg/ml of ardipusilloside I for 24 h and 48 h. (D) Mc3 cells were treated with 5.0, 7.5, 10.0, and 12.5 μg/ml of ardipusilloside I for various times. Cell viability was determined by the MTT assay. Each bar represents the mean ± SE (n = 3).
