Discovery of All-d-Peptide Inhibitors of SARS-CoV-2 3C-like Protease

During the replication process of SARS-CoV-2, the main protease of the virus [3-chymotrypsin-like protease (3CLpro)] plays a pivotal role and is essential for the life cycle of the pathogen. Numerous studies have been conducted so far, which have confirmed 3CLpro as an attractive drug target to combat COVID-19. We describe a novel and efficient next-generation sequencing (NGS) supported phage display selection strategy for the identification of a set of SARS-CoV-2 3CLpro targeting peptide ligands that inhibit the 3CL protease, in a competitive or noncompetitive mode, in the low μM range. From the most efficient l-peptides obtained from the phage display, we designed all-d-peptides based on the retro-inverso (ri) principle.
