| In vitro study | IU1 specifically binds to the active form of usp14. IU1 inhibits USP14 by inhibiting its docking to the proteasome, whereas it inhibits the binding of USP14 to 8 other DUBs, IsoT, UCH37, BAP1, UCH-L1, UCH-L3, USP15, USP2, USP7 had little or no inhibitory activity. USP14 was rapidly inhibited by the addition of IU1 and the inhibition was rapidly reversed after removal. IU1 inhibits usp14-induced chain modification and reduces the electrophoretic mobility of types by Ub-CCNB. IU1 enhances Ub-CCNB degradation of the proteasome in the presence of usp14. In the study of protein toxicity mechanism, IU1 promotes the degeneration of tau and reduces by TDP-43, ATXN3, and glial fibrillary acidic protein (GFAP). |

| biological activity | IU1 is a cell-permeable, reversible proteasome (proteasome) selective inhibitor. when acting on USP14, IC50 is 4.7 μM, and the selectivity when acting on IsoT is 25 times higher. IU1 can induce autophagy. |

| in vitro study | IU1 specifically binds to the active form of USP14. IU1 inhibits USP14 by inhibiting its attachment to the proteasome, while 8 other DUBs, IsoT, UCH37, BAP1, UCH-L1, UCH-L3, USP15, USP2, USP7 have little or no inhibitory activity. IU1 was added to quickly inhibit USP14. After removal, the inhibition was quickly reversed. IU1 inhibits USP14-induced chain modification and reduces electrophoretic mobility of Ub-CCNB types. In the presence of USP14, IU1 enhances the Ub-CCNB degradation of the proteasome. In the study of protein toxicity mechanism, IU1 promotes the degradation of tau and reduces TDP-43, ATXN3, and glial fibrillary acidic protein (GFAP). |
