The cells were treated with H2O2 (400 μM) to induce oxidative stress. ROS concentrations were determined by 2′,7′-dichlorofluorescein diacetate assay staining.
Values in bold indicate ATP or MTS assay log EC50 differing by >1 log unit from cell count EC50, or ATP or MTS assay Emax differing by >25% from the cell count Emax. ND, valid curve fits could not be
