Protective effect of PICE against H2O2-induced oxidative damage in rat cardiomyoblast H9c2 cells. Cells were pretreated with or without test compound for 24 h prior to incubation with H2O2 for 1 h. Data are represented as mean ± SD of triplicate tests. Group a was pretreated with 20 M EDA, and groups b to e were pretreated with PICE under concentration of 0.04, 0.2, 1, and 5 μM, respectively. # versus control group; *, ** versus H2O2 group.
