Biological Activities
Compounds
Conditions
Dryopteris wallichiana contains novel phloroglucinol-terpenoid compounds that demonstrate significant inhibitory effects against SARS-CoV-2. Through target-based virtual screening and LC/MS-guided isolation, researchers identified specific bioactive compounds within the plant that successfully combat the virus in Vero E6 and Calu-3 cells. Notably, compounds 3 and 4 derived from the plant primarily inhibit the SARS-CoV-2 3CLpro enzyme with effective binding values. Molecular dynamics modeling further confirms that these plant-derived substances interact with the viral protease through hydrogen and hydrophobic bonds. Consequently, these compounds serve as promising lead candidates for the future development of anti-SARS-CoV-2 drugs.
