PLpro inhibitor

PLpro inhibitor is a potent inhibitor of papain-like protease (PLpro) with an IC50 of 2.6 μM[1]. PLpro inhibitor inhibits SARS-CoV-2 PLpro with an IC50 of 5.0 μM and an EC50 of 21.0 μM[2].

ChEBI: KOM70144 is a benzamide that is GRL-0617 in which one of the hydrogen's of the primary amino group is replaced by an acetyl group. It an inhibitor of SARS-CoV and SARS-CoV-2 papain-like protease (PLpro) with an IC50 of 2.6 muM and 5.0 muM, respectively. It also inhibits SARS-CoV and SARS-CoV-2 infection of Vero E6 cells in vitro (EC50 values are 13.1 and 21 muM, respectively). It has a role as a protease inhibitor and an anticoronaviral agent. It is a member of naphthalenes, a member of benzamides, a secondary carboxamide and a member of acetamides. It is functionally related to a GRL-0617.
