It is an inhibitor of Mpro (otherwise known as 3CLpro), a viral encoded protease that cleaves and activates functional proteins involved in viral replication and transcription. GC-373 has been shown to inhibit the Mpro target in various coronavirus strains, including feline, mink, and ferret Mpro. Along with its prodrug, GC-376, GC-373 was recently investigated in vitro in cell culture against SARS-Cov-2 Mpro. The results showed potent inhibition of the target, suggesting that GC-373 holds therapeutic potential for Covid-19."}]
