Protective effect of SA, Rb1 and SA-Rb1 4:6 on EA.hy926 cells against H2O2-induced cell injury was determined by MTT assay. a Cell viability (% relative to control) verses increased concentrations of SA, Rb1 and SA-Rb1 4:6 (1–150 μM) against H2O2 induced cell damage. b Concentration-effect curves of restored cell viability against H2O2 treatment with increasing concentrations of SA, Rb1 and SA-Rb1 4:6 (1–150 μM) were generated by CompuSyn software. Data shown are mean ± SEM, n > 3. c CI values were plotted as a function of restored cell viability (Fa) by ‘CompuSyn’ software. Fa. Fa values correspond to restored cell viability % relative to control. Dotted line is the reference line, where CI value equals 1; solid line represents CI values at different Fa
