Catalog Number: 4485
Chemical Name: 1-[5-[(2,4-Difluorophenyl)thio]-4-nitro-2-thienyl]-ethanone
Biological Activity
Inhibitor of ubiquitin-specific protease (USP) 7 (EC50 = 8.6 μM); also inhibits the closely related deubiquitinase (DUB) USP47. Demonstrates downstream inhibition of HDM2 and claspin in vitro. Inhibits USP7-mediated p53 deubiquitination. Blocks deubiquitination of Tip60 (KAT5) histone lysine acetyltransferase.
