生物活性 | K777 is a potent, orally active and irreversiblecysteine proteaseinhibitor. K777 is also a potentCYP3A4inhibitor with anIC50of 60 nM and a selectiveCCR4antagonist featuring the potent chemotaxis inhibition. K777 irreversibly inhibits Cruzain, the major cysteine protease ofTrypansoma cruzi, andcathepsins BandL. K777 is a broad-spectrum antiviral by targeting cathepsin-mediated cell entry. K777 inhibitsSARS-CoVandEBOVpseudovirus entry withIC50values of 0.68 nM and 0.87 nM, respectively[1][2][3]. | ||||||||||||||||

体外研究 (In Vitro) | K777 (K11777) can inhibit entry driven by other viral envelope proteins, HIV-based pseudotypes bearing spikes from coronaviruses (SARS-CoV, HCoV-229E, NL63, MERS-CoV) or glycoproteins from filoviruses (EBOV, SUDV, TAFV, RESTV, BEBOV and MARV) are examined. K777 inhibits SARS-CoV, HCoV-229E, NL63, MERS-CoV, EBOV, SUDV, TAFV, RESTV, BEBOV, MARV and Nipah pseudovirus entry with IC50values of 0.68 nM, 1.48 nM, 6.78 nM, 46.12 nM, 0.87 nM, 1.14 nM, 2.26 nM, 3.37 nM, 5.91 nM, 1.9 nM and 0.42 nM, respectively. In contrast, 100 nM K777 does not inhibit infection mediated by envelope glycoproteins from an alphavirus (CHIKV), a rhabdovirus (VSV), a flavivirus (HCV), the retroviruses MLV-A and XMRV or two arenaviruses, Lassa and Junin virus[1]. | ||||||||||||||||
体内研究 (In Vivo) | K777 (K11777; 35-105 mg/kg; oral administration; twice a day; for 10 days; C57BL/6 IFN-γR-KO mice) treatment rescues mice from otherwise lethal infections[4].
