The cytotoxicity of 15 disassembled groups from PD on PAC cells. The IC50 values of 15 disassembled groups on PAC cells (A, B) at 72 h. The inhibitory effect on PAC cells (C, D) after treated with BTW at concentrations of 0, 25, 37.5, 50, 75 and 100 μg/mL for a period time of 24, 48 and 72 h. Data are presented as mean ± S.D. of triplicate independent experiments. *p < 0.05, ***p < 0.001 compared with the control
