    TKB272

    CAS:
    <p>TKB272 is an orally active antiviral agent that selectively targets the main protease (Mpro) of SARS-CoV-2, effectively inhibiting the infection and replication of various strains, including Omicron variants (such as XBB.1.5 and EG.5.1). It exhibits an enzyme inhibitory activity with an IC50 of 0.7 µM against SARS-CoV-2WK-521 Mpro and shows potent antiviral activity at the cellular level with an EC50 as low as 2.6 nM in HeLahACE2-TMPRSS2 cells against the BQ.1.1 strain. TKB272 also has a CC50 of 98 µM, indicating low cytotoxicity. Furthermore, it demonstrates a significant suppression of SARS-CoV-2XBB.1.5 replication in the B6.Cg-Tg(K18-hACE2)2-Prlmn/J transgenic mouse model, suggesting potential use in the research of SARS-CoV-2 infections.</p>
