Antiviral activity of Chen2 (a) and ChenR (b) peptides in SARS-CoV-2-mediated infection of human pulmonary cells. SARS-CoV-2 yield inhibition (%), and cellular viability of Calu-3-infected cells are depicted in the graphs. Infected cells were incubated with a range of concentrations of each peptide. The SARS-CoV-2 yield inhibition (%) values were calculated in comparison to the negative control (infected, untreated cells). The cell viability assessed by MTT assay was expressed as % of mortality values and represents the means of eight repetitions with SD error bars. The SARS-CoV-2 Yield Inhibition (%) is a means of three repetitions with SD error bars.
