ECDD-S16 exhibits broad-spectrum antiviral activity and inhibits an early, pH-dependent step of influenza virus entry.
Respiratory viral infections continue to pose a significant global health burden, highlighting the urgent need for broad-spectrum antiviral therapeutics. In this study, we identified ECDD-S16, an arylnaphthalene lignan derivative, as a potent broad-spectrum antiviral. ECDD-S16 exhibited dose-dependent antiviral activit...
