Fig. 1 — Effect of TW-37 on the viability in human oral cancer cell lines. MC-3 and HSC-3 cell lines were treated with DMSO or 5 μM of TW-37 for 48 h. a Cell viability (%) was assessed by trypan blue exclusion assay. The data shown in the graph represent the mean ± SD of triplicate experiments. *, p < 0.05 compared with the control. b Cytotoxic effect of TW-37 was determined by Live/dead assay kit. Live cells (green fluorescence) and dead cells (red fluorescence) were observed under a light microscope (magnification, × 200)
