While vaccines and antivirals are now being deployed for the current SARS‐CoV‐2 pandemic, we require additional antiviral therapeutics to not only effectively combat SARS‐CoV‐2 and its variants, but also future coronaviruses. All coronaviruses have relatively similar genomes that provide a potential exploitable opening to develop antiviral therapies that will be effective against all coronaviruses. Among the various genes and proteins encoded by all coronaviruses, one particularly “druggable” or relatively easy‐to‐drug target is the coronavirus Main Protease (3CL^pro or Mpro), an enzyme that is involved in cleaving a long peptide translated by the viral genome into its individual protein components that are then assembled into the virus to enable viral replication in the cell. Inhibiting Mpro with a small‐molecule antiviral would effectively stop the ability of the virus to replicate, providing therapeutic benefit. In this …
