Feature Story
Optimization of the Prodrug Moiety of Remdesivir to Improve Lung Exposure/Selectivity and Enhance Anti-SARS-CoV-2 Activity

Never thought my lab would work on anti-viral drugs since we mainly focus on anti-cancer drug discovery, but COVID19 changed everything. Even if the pandemic ends today, there will be patients die from severe disease of COVID19. We still need anti-viral drugs to treat COVID19 with severe disease, since Gilead's Remdesivir only has limited efficacy in these patients, while Pfizer's Paxlovid only works in COVID19 patient with moderate disease but does not work in COVID19 patients with severe disease. By applying our new STAR system (structure-tissue selectivity-activity-relationship), we further optimized remdesivir for better anti-SARS-CoV-2 activity and better tissue (lung) selectivity. Hope this will help to treat COVID19 patients with severe disease. "Optimization of the Prodrug Moiety of Remdesivir to Improve Lung Exposure/Selectivity and Enhance Anti-SARS-CoV-2 Activity".
