Background:

HBX 19818 is a specific inhibitor of ubiquitin-specific protease 7 (USP7), with an IC50 of 28.1 μM. IC50: 28.1 μM (USP7)[1]

HBX 19818 is an inhibitor of USP7, with an IC50 of 28.1 μM. HBX 19818 shows no effects on USP8, USP5, USP10, CYLD, UCH-L1, UCH-L3 or on SENP1, a SUMO protease, with IC50s of >200 μM. HBX 19818 selectively inhibits USP7 with IC50 of ∼6 μM in in human cancer cells. In addition, HBX 19818 (1.5, 4, 12, 36, or 100 μM) inhibits USP7 deubiquitination of polyubiquitinated p53. HBX 19818 (30 μM) also causes significantly higher levels of Mdm2 polyubiquitinated forms in USP7-overproducing HEK293 cells than those in DMSO-treated control cells. HBX 19818 inhibits HCT116 proliferation in a dose-dependent manner, with an IC50 of ∼2 μM[1].
