Antiviral compound blocks SARS-CoV-2 from entering cells

Antiviral compound blocks SARS-CoV-2 from entering cells: Scientists at Washington University School of Medicine in St. Louis have developed a chemical compound that interferes with a key feature of many viruses that allows the viruses to invade human cells. The compound, called MM3122, was studied in cells and mice and holds promise as a new way to prevent infection or reduce the severity of COVID-19 if given early in the course of an infection, according to the researchers.
