In vitro Inhibitory activity profiles of 6g, 6i, and 6j against SARS-CoV-2. (a) Quantitative RT-PCR assays were performed to measure viral copy number in the cellular supernatant. The y-axis indicates the percentage inhibition of the virus relative to samples treated with DMSO (vehicle). (b) Cell viability test. The y-axis represents percent of cell viability relative to the sample treated with DMSO (vehicle). The y-axis indicates the percent inhibition of the virus relative to the DMSO treated sample (vehicle). Means ± SDs of three biological replicates are presented.
