Design of a SARS-CoV-2 papain-like protease inhibitor with antiviral efficacy in a mouse model. Science, 383:1434-1440, 2024 Cited by PubMed Abstract: The emergence of SARS-CoV-2 variants and drug-resistant mutants calls for additional oral antivirals. The SARS-CoV-2 papain-like protease (PL) is a promising but challenging drug target. We designed and synthesized 85 noncovalent PL inhibitors that bind to a recently discovered ubiquitin binding site and the known BL2 groove pocket near the S4 subsite. Leads inhibited PL with the inhibitory constant K values from 13.2 to 88.2 nanomolar. The co-crystal structures of PL with eight leads revealed their interaction modes. The in vivo lead Jun12682 inhibited SARS-CoV-2 and its variants, including nirmatrelvir-resistant strains with EC from 0.44 to 2.02 micromolar. Oral treatment with Jun12682 improved survival and reduced lung viral loads and lesions in a SARS-CoV-2 infection mouse model, suggesting that PL inhibitors are promising oral SARS-CoV-2 antiviral candidates.
