Description: HBX 41108 is an inhibitor of ubiquitin-specific protease (USP) 7. HBX 41108 inhibits USP7 deubiquitinating activity with an IC(50) in the submicromolar range. HBX 41,108 was shown to affect USP7-mediated p53 deubiquitination in vitro and in cells. As RNA interference-mediated USP7 silencing in cancer cells, HBX 41,108 treatment stabilized p53, activated the transcription of a p53 target gene without inducing genotoxic stress, and inhibited cancer cell growth. HBX 41,108 induced p53-dependent apoptosis as shown in p53 wild-type and null isogenic cancer cell lines.

Synonym: HBX 41108; HBX-41108; HBX41108; HBX 41,108; HBX-41,108; HBX41,108.
