Broad-spectrum antiviral activity of Spatholobus suberectus Dunn against SARS-CoV-2, SARS-CoV-1, H5N1, and other enveloped viruses.
Scientists have found that an extract of Spatholobus suberectus Dunn (SSP), a medicinal plant, has broad-spectrum antiviral properties against SARS-CoV-1 and 2, HIV-1, and H5N1. SSP effectively inhibits viral entry, with EC values ranging from 3.6 to 5.1 μg/ml. Pre-treatment of pseudovirus or target cells with SSP showed consistent inhibitory activities with the respective EC value of 2.3 or 2.1 μg/ml. SSP blocked both SARS-CoV-2 spike glycoprotein and the host ACE2 receptor without toxic behavior. This plant extract has promising potential to be developed as a drug candidate for preventing and treating COVID-19 and other emerging enveloped viruses.
