Background

GC-376 is a 3C-like protease (3CLpro or Mpro) inhibitor that stops the cleavage and activation of functional viral proteins required for replication and transcription in host cells1. The compound is known as a direct acting antiviral (DAA) for coronaviruses, and was initially developed using structure-guided design to combat MERS-Cov infections1,2. In addition, GC-376 displays potent activity against various coronaviruses such as feline, ferret, and mink Mpro coronavirus3,4,1,5. A prodrug of GC-373, GC-376 has recently been used to test inhibition of SARS-Cov-2 Mpro in vitro, and results show potent inhibition of this target1. These results suggest that GC-376, and its metabolites may have therapeutic potential for Covid-19.
