Antiviral activity of norwogonin, oroxylin A, mosloflavone, and ribavirin against Enterovirus 71 (EV71). (A) Antiviral activity and (B) cytotoxicity of norwogonin, oroxylin A, mosloflavone and ribavirin were measured in Vero cells. Vero cells were infected with EV71 and then treated with the indicated concentrations (0.4, 2, 10, and 50 μg/mL) of norwogonin, oroxylin A, mosloflavone for 48 h. The antiviral activity was investigated using a CPE reduction assay. Data are presented as mean ± SD. from three independent experiments, each carried out in triplicate. ^*p<0.01; ^**p<0.001; ^***p<0.0001. one-way analysis of variance (ANOVA) with Tukey’s post hoc test.
