Functional and Structural Characterization of Treatment-Emergent Nirmatrelvir Resistance Mutations at Low Frequencies in the Main Protease (Mpro) Reveals a Unique Evolutionary Route for SARS-CoV-2 to Gain Resistance

Abstract excerpt

BACKGROUND: The main protease (Mpro) is one of the most attractive targets for antiviral drug discovery against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Mutations in Mpro have been linked to resistance against nirmatrelvir-ritonavir (NIR-RIT), an important therapy for SARS-CoV-2 infection. This study aimed to identify low-frequency antiviral resistance mutations in Mpro from NIR-RIT-treated...
