(B) The inhibitory effects of JZ and remdesivir on SARS-CoV-2 in vitro. (C) Inhibitory effect of JZ and remdesivir on plaque formation of SARS-CoV-2. (D) The quantitative analysis of the plaque formation in different groups was analyzed by SPSS ver. 25.0. Data were presented as the mean ± SD obtained from three separate experiments. * p < 0.05; ** p < 0.01; *** p < 0.001, compared with SARS-CoV-2-infected cells.
