Cell viability 72 h after exposure to various EEP concentrations. Cell survival is expressed as a percentage relative to the negative control (DMSO). EEP at a concentration of 50 μg/mL, exhibited cytotoxic activity against HCT-116 and OVCAR-8 cells, without a significant difference compared with the positive control (0.5 μM doxorubicin). Compared with the other two cell lines, SF-295 cells exposed to EEP at a concentration of 50 μg/mL exhibited a significantly higher survival rate compared with those exposed to doxorubicin. Each bar graph represents the mean, and the error bars represent ± SD of three independent experiments performed in triplicate
