New antiviral compound blocks Covid virus from entering cells: Study

Updated: few hours ago

Washington, Oct 13 (PTI) Scientists have developed a chemical compound that they say could prevent infection from SARS-CoV-2 virus or reduce the severity of COVID-19 if given early in the course of an infection.

The compound, described in the journal Proceedings of the National Academy of Sciences, targets a key human protein called transmembrane serine protease 2 (TMPRSS2) that coronaviruses harness to enter and infect human cells.

The compound, called MM3122, interferes with a key feature of many viruses that allows them to invade human cells, according to the researchers at Washington University School of Medicine in the US.
