The protective effect of SA, Rb1 and SA-Rb1 4:6 on EA.hy926 cells against cytotoxicity induced by Hcy-Ado-TNF was determined by MTT assay. Cell viability, as determined by MTT for SA (a), Rb1 (b) and SA-Rb1 4:6 (c) following treatments with Hcy-Ado-TNF in EA.hy926 cells. Cell viability was expressed as a percentage compared to control. Data shown are mean ± SEM, n > 3. * P < 0.05, ** P < 0.01, *** P < 0.001 in comparison to other combinations in the respective cell lines. d Concentration-effect curves of SA, Rb1 and SA-Rb1 4:6 (10–150 μM) on restored cell viability generated by CompuSyn software. e CI values were plotted as a function of fractional restored cell viability (Fa) by CompuSyn software. Fa values correspond to % cell viability relative to control. Dotted line is the reference line, where CI value equals 1; solid line represents CI values at different Fa
