IU1 is a potent and selective small-molecule inhibitor of Usp14, a proteasome-associated deubiquitinating enzyme in habiting the degradation of ubiquitin-protein conjugates, with the inhibition constant IC50 ranging from 4 to 5 μM. Structural analysis reveals IU1 is an active-site-directed thiol protease inhibitor that binds to the activated form of Usp14 preventing it docking on the proteasome in a rapid but reversible manner. According to the results of previous studies, it has shown that IU1 failed to inhibit Usp14 in the absence of proteasomes as well as eight deubiquitinating enzymes (DUBs) of human origin and Ub-AMC hrolysis by proteasomes lacking Usp14.
