Inhibitor of ubiquitin-specific peptidase 4 (USP4), USP5/isopeptidase T (IsoT) and UCH-L1 deubiquitinating enzyme (DUB) activity (IC50 values are 1.5, 5.9 and 22.3 μM, respectively). Shows no significant inhibition of UCH-L3, USP2, and USP8 activities. Decreases release of TNF-α (IC50 = 0.09 nM) from RBL-2H3 mast cells. Displays anti-cancer activity decreasing viability in human colonic carcinoma cells.
