Scientists at the University of Alberta have shown that the drug remdesivir is highly effective in stopping the replication mechanism of the coronavirus that causes COVID-19, according to new research published today in the Journal of Biological Chemistry. The paper, Folio reports, follows closely on research published by the same lab in late February that demonstrated how the drug worked against the Middle East Respiratory Syndrome (MERS) virus, a related coronavirus. The paper demonstrates how remdesivir, developed in 2014 to fight the Ebola epidemic, works in detail. He likens the polymerase to the engine of the virus, responsible for synthesizing the virus’ genome.
