IC50: 0.1 μM (papain-like protease)[1]
XR8-89 is a potent papain-like protease (PLpro) inhibitor with an IC50 value of 0.1 μM. XR8-89 induces conformational changes in SARS-COV-2 papain-like protease, inhibiting SARS-CoV-2 replication. XR8-89 can be used for SARS-CoV-2 research[1].
XR8-89 induces conformational changes manly in BL2 region and increases the activity against PLpro[1].
