“…Both compounds inhibited 195 cytopathic effects during infection and the viral replication ( Figure 4B, C, D, S5, and S6). Overall, five compounds, inhibiting downstream signaling of GFRs, prevented SARS-CoV-2 replication at clinically achievable concentrations ( Figure 4B and 5) (Eskens et al, 2001;Fucile et al, 2014;Martinez-Garcia et al, 2012;Munster et al, 2016;Sarker et al, 2015), emphasizing the importance of GFR signaling during SARS-CoV-2 infection and revealing clinically available 200 treatment options as drug candidates for COVID-19.…”
