Cat. No. 4285
Chemical Name: 7-Chloro-9-oxo-9H-indeno[1,2-b]pyra
Biological ActivityInhibitor of ubiquitin-specific protease (USP) 7 activity (IC50 = 424 nM). Displays uncompetitive inhibition. Also inhibits USP7-mediated p53 deubiquitination (IC50 = 0.8 μM). Stabilizes p53 and inhibits cancer cell growth; induces p53-dependent apoptosis in p53 wild type and null isogenic cancer cell lines.
