Concentration-dependent viral titer reduction for the highly promising steroids (β-sitosterol and β-sitosterol-O-glucoside) as determined via PRA. (a) Chemical structure of β-sitosterol and β-sitosterol-O-glucoside; (b) Validation of the anti-influenza efficacy for both compounds were evaluated against the A/H1N1 (dark pink) and the A/H5N1 (light brown), and GraphPad Prims 5.01 software was used to plot the viral inhibition percentages against compound concentrations.
