A sulfonyldiphenylene-bis-dicyclohexylaminoacetamide compound that acts as a potent and selective inhibitor against adenovirus AVP, the cysteine proteinase critical for virion assembly and maturation, by targeting simultaneously AVP co-factor pVIc (GVQSLKRRRCF) N-terminal binding pocket (Ki = 150 nM) and AVP-pVIc substrate-binding site (Ki = 400 nM), blocking not only AVP-pVIc active complex formation/AVP activation (IC50 = 140 nM; [substrate] = 5 µM & [pVIc] = 40 µM), but also AVP-pVIc active complex catalytic activity (IC50 = 490 nM; [substrate] = 5 µM). Does not affect the activity of the serine protease trypsin or the cysteine protease papain even at concentrations as high as 10 µM.
