Biological Activity
X77 is considered as a reference standard in number of docking and x-ray studies. X77 is a high affinity non-covalent inhibitor of the SARS-CoV-2 main protease (SARS-CoV-2 Mpro). Its calculated dissociation constant (Kd) is 0.057 μM. X77 is an analog of ML188 a selective non-covalent SARS-CoV 3CLpro inhibitor (IC50 = 1.5 μM).
