Pathogenic coronaviruses are a major threat to global public health, as shown by severe acute respiratory syndrome coronavirus, or SARS-CoV; Middle East respiratory syndrome coronavirus, known as MERS-CoV; and the newly emerged SARS-CoV-2, the virus that causes COVID-19 infection.
The study, “3C-like protease inhibitors block coronavirus replication in vitro and improve survival in MERS-CoV-infected mice,” appears in the Aug. 3 issue of the medical journal Science Translational Medicine. It reveals how small molecule protease inhibitors show potency against human coronaviruses. These coronavirus 3C-like proteases, known as 3CLpro, are strong therapeutic targets because they play vital roles in coronavirus replication.
