Protective effect of DS, SQ and DS-SQ 6:4 on EA.hy926 cells against H2O2-induced cell injury by restoring reduced cell viability. Cell viability was assayed by the MTT method (n = 4) in EA.hy926 cells for 20 h. Cell viability was expressed as a percentage compared to H2O2 stimulation only. Data shown are means ± SEM, n > 3. Cell viability (% relative to control) versus increased concentrations of (a) DS, (b) SQ and (c) DS-SQ 6:4 (10–300 μg/mL) against H2O2 induced cell damage. #P < 0.05 vs control. * P < 0.05 vs H2O2 treatment only. ** P < 0.01 vs H2O2 treatment only. *** P < 0.001 vs H2O2 treatment only. d. CI values were plotted as a function of restored cell viability (Fa) by ‘CompuSyn’ software. 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
