Antiviral activity of (A) pentoxifylline and (B) the standard antiviral agent ribavirin against Japanese encephalitis virus (JEV) evaluated using the plaque reduction assay. Dose-dependent reduction in JEV plaques obtained in porcine stable kidney (PS) cells with pentoxifylline (represented as bars), where the x-axis represents the various concentrations of the compound and the left-hand y-axis represents the percent reduction of JEV plaques. The viability of cells is represented as a line graph superimposed on the bar diagram, where the right-hand y-axis represents the percent viability of PS cells.
