 Use of HBX 41108


HBX 41108 is an uncompetitive inhibitor of ubiquitin-specific protease 7 (USP7) with an IC50 of 424 nM. HBX 41108 inhibits USP7-mediated p53 deubiquitination to stabilize p53 and inhibits cancer cell growth. HBX 41108 induces p53-dependent apoptosis in p53 wild type and null isogenic cancer cell lines[1][2].
