Discovery of potential inhibitors targeting SARS-CoV-2 Mpro.

The coronavirus disease (COVID-19) pandemic, resulting from human-to-human transmission of a novel severe acute respiratory syndrome coronavirus (SARS-CoV-2), has caused a global health emergency. The lack of a specific drug or treatment strategy against this disease makes it devastating. Given that the main protease (Mpro) of SARS-CoV-2 plays an indispensable role in viral polyprotein processing, its successful inhibition prevents viral replication and constrains virus spread. Therefore, developing an effective SARS-CoV-2 Mpro inhibitor to treat COVID-19 is imperative.
