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.
Groutas 鈥� along with Kansas State University virologists Yunjeong Kim and Kyeong-Ok
"KC" Chang 鈥� published the study 鈥� titled 鈥�3C-like protease inhibitors block SARS-CoV-2
replication in vitro and increase survival in MERS-CoV-infected mice鈥濃�� which appears
in the Aug. 3 issue of the prestigious medical journal . 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.
"Vaccine developments and treatments are the biggest targets in COVID-19 research,
and treatment is really key," said Chang, professor of diagnostic medicine and pathobiology.
"This paper describes a protease inhibitor targeted by a viral protease, which is
a well-known therapeutic target."
Chang and Kim have been using National Institutes of Health grants to develop antiviral drugs to treat MERS and human norovirus infections. Their work extends to other human viruses, such as rhinoviruses and SARS-CoV-2.
The study demonstrates that this series of optimized coronavirus 3CLpro inhibitors blocked replication of the human coronaviruses MERS-CoV and SARS-CoV-2 in cultured cells and in a mouse model for MERS. These findings suggest that this series of compounds should be investigated further as a potential therapeutic for human coronavirus infection.
Co-collaborators on the research include teams lead by Bill Groutas at 成人头条 State University and Stanley Perlman at the University of Iowa, and Scott Lovell at the University of Kansas.
"Drs. Groutas, Perlman and Lovell brought decades of experience to our research team," Chang said. "We would not have been able to come this far without important collaborations with our colleagues at other institutions."
鈥淥ur studies have demonstrated proof-of-concept, and we are excited about our partnership with CoCrystal Pharma to explore the development of this series of compounds as COVID-19 therapeutics,鈥� Groutas said.
The new compounds in the publication are exclusively licensed and for COVID-19.
