Debrisoquine has been identified as a inhibitor of TMPRSS2 protease, which is involved in the viral entry process of SARS-CoV-2. In a laboratory study, it showed antiviral activity by blocking the ability of the virus to enter human lung cells.^[3]

The guanidine part of the molecule also appears in guanoxan and guanadrel.^{[citation needed]} The 7-bromo analog of debrisoquine is called guanisoquin.^{[citation needed]}
