Protective effects of compound 2 against H₂O₂-induced cell oxidative stress damage in MIN6 cells. (A) Cells were treated with increasing concentrations of H₂O₂ for 12 h. (B) Cells were treated with various concentrations of compound 2 for 4 h, and then exposed to 200 μM H₂O₂ for 12 h. (C) EC₅₀ of compound 2 on H₂O₂-induced MIN6 cells. Data are presented as means ± standard deviations (SDs) of three independent experiments. * p < 0.05, ** p < 0.01, compared with com.2 (0 μM).
