Mini-Spotlight: A New Fluorogenic Substrate for SARS-CoV/SARS-CoV-2 Mpro­

We are pleased to offer another new fluorogenic substrate for the SARS-CoV and SARS-CoV-2 Main Protease (Mpro).  This substrate contains the nsp4/nsp5 cleavage sequence, GVLQ↓SG19, and works as a generic peptide substrate for several coronavirus.  The main protease (Mpro­), also called endopeptidase C30 or 3C-like proteinase (3CLpro), controls viral replication activities, and is a prime therapeutical target. Both substrates and inhibitors of SARS-CoV-2 Mpro are of interest.1,2,3,4
