Biological Activity

Inhibitor of 19S regulatory particle associated deubiquitinating enzymes (DUBs), UCHL5 and USP14. Shows minimal inhibition of UCHL-1, UCHL-3, USP2, USP7, USP, BAP1 and proteasome activity. Induces apoptosis by cathepsin D-dependent caspase-cleavage (IC50 = 0.5 μM). Displays antitumor activity in vivo.
