Abstract
The present invention relates to an antiviral composition and a screening method thereof for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that occurred in Wuhan, China in 2019. An extract from leaves or unfertilized female flowers of Cannabis sativa L. or its fraction, and the cannabinoids (CBDs) molecules isolated from it have high binding strength and stability to SARS-CoV-2 MPpro, thereby inhibiting its action as the main protease, to provide a useful lead molecule that can be used alone or in combination with other drugs to treat SARS-CoV-2.
