From: Gramicidin S and melittin: potential anti-viral therapeutic peptides to treat SARS-CoV-2 infection

Anti SARS-CoV-2 activity of gramicidin S and melittin in vitro: (a). Relative viral RNA (%) vs. Log concentrations of gramicidin S (µg). (b) Relative viral RNA (%) vs. Log concentrations of melittin (ng). The graphs represent the Ct values of N-gene calculated using RT-qPCR in the supernatants. The Log EC50 value of gramicidin S (0.1963) corresponds to 1.571 µg and Log EC50 value (2.826) of melittin corresponds to 0.656 µg as shown in the graph.
