- Formula:C39H46N4O7S2
- Molecular Weight:746.94
InChIKey: ASUKMBNQFXCWPX-WJFVNNBYSA-N
SMILES: O=S(O)(C1=CC=C(C=C1)C)=O.O=S(/C=C/[C@H](CCC2=CC=CC=C2)NC([C@@H](NC(N3CCN(CC3)C)=O)CC4=CC=CC=C4)=O)(C5=CC=CC=C5)=O
Biological Activity: K777 tosylate is a potent, orally active and irreversible cysteine protease inhibitor. K777 tosylate is also a potent CYP3A4 inhibitor with an IC50 of 60 nM. K777 tosylate irreversibly inhibits Cruzain, the major cysteine protease of Trypansoma cruzi, and cathepsins B and L. K777 tosylate is a broad-spectrum antiviral by targeting cathepsin-mediated cell entry. K777 tosylate inhibits SARS-CoV and EBOV pseudovirus entry with IC50 values of 0.68 nM and 0.87 nM, respectively[1][2][3].
