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 (K_i = 150 nM) and AVP-pVIc substrate-binding site (K_i = 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.

Primary Target
AVP co-factor pVIc (GVQSLKRRRCF) N-terminal binding pocket''Reversible: yes''Secondary Target
AVP-pVIc substrate-binding site
