Structural Basis of Covalent Inhibitory Mechanism of TMPRSS2-Related Serine Proteases by Camostat.

ABSTRACT: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the viral pathogen causing the coronavirus disease 2019 (COVID-19) global pandemic. No effective treatment for COVID-19 has been established yet. The serine protease transmembrane protease serine 2 (TMPRSS2) is essential for viral spread and pathogenicity by facilitating the entry of SARS-CoV-2 into host cells. The protease inhibitor camostat, an anticoagulant used in the clinic, has potential anti-inflammatory and antiviral activities against COVID-19. However, the potential mechanisms of viral resistance and antiviral activity of camostat are unclear. Herein, we demonstrate high inhibitory potencies of camostat for a panel of serine proteases, indicating that camostat is a broad-spectrum inhibitor of serine proteases. In add
