Fig. 3From: 6-methylmercaptopurine riboside, a thiopurine nucleoside with antiviral activity against canine distemper virus in vitroCDV plaque-reduction assay with 6MMPr and RIB treatments. VerodogSLAM cells were inoculated with samples of antiviral activity assays. Plaque reduction values of 6MMPr (a) and RIB (b) assays represent the average ± SD from three independent experiments compared with untreated infected cells. Plaques were visualized by crystal violet stainingBack to article page
