Biological Activity for P 22077

P 22077 is an 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.

P22077 was seen to induce tumor cell death.

P22077 was seen to induce (tumor) cell death with EC50 values in the low micromolar range. P22077 inhibition exhibited changes in ubiquitylated protein levels that are distinct from the broad specificity inhibitor.
