General description

A cell-permeable pyrrolylpyrrolidinyl-ethanone that inhibits the proteasome association-dependent USP14 deubiquitinase (DUB) activity in a reversible manner (IC50 = 4.7 µM against Ub-AMC hydrolysis), exhibiting little or no activity toward 8 other DUBs. Shown to downregulate tau, TDP-43, ATXN3, GFAP, and free Ub levels in MEF cultures in a dose- (25 to 100 µM), time-, and USP14-dependent manner. USP14-catalyzed trimming of protein surface polyubiquitin chains rescues proteasome-bound proteins from proteolytic degradation and thereby prevents the depletion of free ubiquitin pool in cells. Comparing to b-AP15 (Cat. No. 662140), IU1 does not inhibit UCH37/UCH-L5 (IC50 = 700 µM).
