Abstract

Background: ADAM17 is a metalloprotease implicated in the proteolysis of angiotensin-converting enzyme 2 (ACE2), known to play a critical role in the entry and spread of SARS-CoV-2. In this context, ADAM17 results as a potential novel target for controlling SARS-CoV-2 Infection.

Methods: In this study, we investigated the impact on ACE2 surface expression and the Antiviral efficacy against SARS-CoV-2 Infection of the selective ADAM17 Inhibitor JG26 and its dimeric (compound 1) and glycoconjugate (compound 2) derivatives using Calu-3 human lung cells.

Results: None of the compounds exhibited cytotoxic effects on Calu-3 cells up to a concentration of 25 µM. Treatment with JG26 resulted in partial inhibition of both ACE2 receptor shedding and SARS-CoV-2 Infection, followed by compound 1.

Conclusion: JG26, an ADAM17 Inhibitor, demonstrated promising Antiviral activity against SARS-CoV-2 Infection, likely attributed to reduced sACE2 availability, thus limiting viral dissemination.
