Brilacidin (PMX-30063), a non-peptide defensin-mimetic small molecule, inhibits SARS-CoV-2 viral infection but the anti-viral mechanism is not defined. Here we determined its effect on the specific step of the viral life cycle. Brilacidin blocked SARS-CoV-2 infection but had no effect after viral entry. Brilacidin inhibited pseudotyped SARS-CoV-2 viruses expressing spike proteins from the P.1 Brazil strain and the B.1.1.7 UK strain. Brilacidin affected viral attachment in hACE2-dependent and independent manners depending on the concentrations. The inhibitory effect on viral entry was not mediated through blocking the binding of either the spike receptor-binding domain or the spike S1 protein to hACE2 proteins. Taken together, brilacidin inhibits SARS-CoV-2 infection by blocking viral entry and is active against SARS-CoV-2 variants. |
