Structural basis of main proteases of HCoV-229E bound to inhibitor PF-07304814 and PF-07321332.

ABSTRACT: PF-07321332 and PF-07304814, inhibitors against SARS-CoV-2 developed by Pfizer, exhibit broad-spectrum inhibitory activity against the main protease (M^pro) from various coronaviruses. Structures of PF-07321332 or PF-07304814 in complex with M^pros of various coronaviruses reveal their inhibitory mechanisms against different M^pros. However, the structural information on the lower pathogenic coronavirus M^pro with PF-07321332 or PF-07304814 is currently scarce, which hinders our comprehensive understanding of the inhibitory mechanisms of these two inhibitors. Meanwhile, given that some immunocompromised individuals are still affected by low pathogenic coronaviruses, we determined the structures of lower pathogenic coronavirus HCoV-229E M^pro
