Figure 4. Evaluation of anti-CHIKV activity of silymarin using BHK-CHIKV-NCT replicon cell line.
Silymarin exhibits a statistically significant (P < 0.05) dose-dependent inhibition on the Rluc activity produced by BHK-CHIKV-NCT replicon. The Rluc activity was measured at 48 h post treatment. Vehicle–treated (0.1% DMSO) cells were used as control (“0”) concentration). Data from triplicate assays were plotted and analyzed from a non-parametric correlation (Spearman) two-tailed test (Graph Pad Prism Version 5, Graph Pad Software Inc., San Diego, CA).
