QUICK LINKS

Rupintrivir is an irreversible HRV 3C protease inhibitor, demonstrating in vitro activity against all HRVs tested. HRV 3C protease is essential for the replication of the rhinovirus. By targeting this specific enzyme, rupintrivir helps to disrupt the virus′s life cycle, preventing it from maturing and proliferating. Rupintrivir, belonging to the class of antifolates, is a potent small molecule inhibitor targeting the enzyme dihydrofolate reductase (DHFR). In laboratory applications, in vitro experiments employ cell cultures to investigate the impact of rupintrivir on cellular behavior and response.
