Who could benefit from this research

Could help

Ideal candidates would be individuals with confirmed or at-risk COVID-19 infection who could participate in future preclinical or clinical development stages if a candidate advances.

Less likely to help

In early-stage research, participants will not directly receive a preventive or therapeutic intervention.

What this research studies

This grant supports discovery and optimization of drug candidates that target two viral proteases essential for SARS-CoV-2 replication. Researchers are moving from early chemical hits to lead compounds and studying their pharmacokinetics to see if they could work in living organisms. The project focuses on identifying molecules that specifically inhibit the viral proteases without affecting human enzymes. If successful, these compounds could form the basis for oral antiviral therapies. The work is conducted at Scripps Research Institute with a focus on translating basic chemistry findings into potential medicines.

Why it matters

Potential benefit: If successful, patients could benefit from faster-acting oral antiviral options that prevent or treat COVID-19.

How similar studies have gone: Similar antiviral protease inhibitors have shown promise in preclinical studies, supporting the potential of this approach.
