Icity against pancreatic Cancer Cells To evaluate the cytotoxicity of sinuleptolide
Icity against Pancreatic Cancer Cells To evaluate the cytotoxicity of sinuleptolide and 5-epi-sinuleptolide, the gemcitabinesensitive pancreatic cancer cell line BxPC-3 was treated with dimethyl sulfoxide (DMSO) or various concentrations of sinuleptolide or (��)-Leucine Autophagy 5-epi-sinuleptolide for 24 h, and cell viability was analyzed by way of MTT assays (Figure 2a). Treatment with 5-epi-sinuleptolide resulted in a substantial reduce in cell viability whilst sinuleptolide showed negligible cytotoxic effect. Therefore, the 5-epi-sinuleptolide was selected for the following study. To further examine no matter whether 5-epi-sinuleptolide possessed a selective cytotoxicity, as well as BxPC-3 cells, gemcitabine-resistant PANC-1 cells and HPDE-E6E7, the immortalized pancreatic duct epithelial cells were treated with DMSO or indicated concentrations of 5-epi-sinuleptolideMolecules 2021, 26,a important decrease in cell viability though sinuleptolide showed negligible cytotoxic impact. Hence, the 5-epi-sinuleptolide was chosen for the following study. To further examine whether 5-epi-sinuleptolide possessed a selective cytotoxicity, along with BxPC-3 cells, gemcitabine-resistant PANC-1 cells and HPDE-E6E7, the immortalized pancreatic duct epithelial cells had been treated with DMSO or indicated concentrations of 5-epi-sinuleptolide three of 16 for 24 h. The cytotoxic effects of 5-epi-sinuleptolide on pancreatic cancer cells were superior to these against pancreatic duct epithelial cells (Figure 2b). The half maximal inhibitory concentration of 5-epi-sinuleptolide linked to cytotoxicity in BxPC-3, PANC-1, and HPDE-E6E7 cells was 9.73,of 5-epi-sinuleptolide on pancreaticAs BxPC-3 showed the for 24 h.

As BxPC-3 showed the highest sensitivity to 5-epi-sinuleptolide, it was applied inside the following experiments.Molecules 2021, 26, x FOR PEER REVIEW4 of(a)(b)Figure 2.
