Continued research efforts have elucidated several peptidic small molecules like GC376, boceprevir, and nirmatrelvir with potent anticoronaviral activity bearing optimized amino acid side chain residues. To reduce synthetic complexity and cost, we used simple chemical surrogates that were commercially readily available to develop new inhibitors that mimic the potency of these drug compounds. We synthesized and tested several analogue chimeras of GC376 and boceprevir that have surrogate residues at the P1 and/or P2 position in order to further improve target binding. Both P1 variants with either a nonpolar cyclobutyl or polar thiazol-4-yl alanine resulted in low-micromolar to submicromolar M<sup>pro</sup> inhibitors with strong antiviral activity in cell assays.</p>","PeriodicalId":20,"journal":{"name":"ACS Medicinal Chemistry Letters","volume":"15 11","pages":"2046-2052"},"PeriodicalIF":3.5,"publicationDate":"2024-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11571010/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142674567","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
