Who could benefit from this research

Could help

Ideal candidates are adults with confirmed COVID-19 who could participate in future clinical development or use resulting therapies if approved.

Less likely to help

Patients with non-CCOVID illnesses or those not eligible for protease inhibitor therapies may not benefit.

What this research studies

This project aims to turn promising laboratory findings into real antiviral drugs that inhibit the virus’s proteases and stop replication. The work builds on prior SARS/MERS experience to design covalent and non-covalent inhibitors targeting 3CLpro and PLpro. Researchers will test these compounds with the goal of creating safe, effective drugs for people with COVID-19. The study includes collaborative efforts to optimize potency, selectivity, and antiviral activity, with a focus on translational potential.

Why it matters

Potential benefit: If successful, the project could yield new antiviral drugs that reduce COVID-19 symptoms, hospitalization, and deaths.

How similar studies have gone: Previous work on coronavirus protease inhibitors showed antiviral activity in preclinical models, supporting continued development.
