Growth inhibitory effects of caged xanthones and doxorubicin on KKU-100, KKU-M139, KKU-M156 and Chang cells. Cells were treated with DMSO or with the indicated concentrations of isomorellin, forbesione and doxorubicin for 72 h. Data are presented as the mean ± SE of three independent experiments. ^aP < 0.05, ^bP < 0.01, ^cP < 0.001 vs. DMSO-treated cells.
