Application

P5091 has been used:
  • as a ubiquitin specific peptidase 47 (USP47) inhibitor in 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay to evaluate the cellular viability of MCF-10A cells
  • as a USP7 inhibitor to study the regulatory role for USP7 on inflammasome activation
  • as USP7 inhibitor in drug susceptibility assays to study its effect on bone marrow−resident tumor cells (BMRTCs)/ circulating tumor cells (CTCs)

Biochem/physiol Actions

P5091 is a cell permeable, potent and specific inhibitor of deubiquitylating enzyme USP7 (Ubiquitin-Specific Protease-7) that induces HDM2 polyubiquitylation and accelerates degradation of HDM2. P5091 induces apoptosis in MM cells resistant to conventional and bortezomib therapies. P5091 inhibits tumor growth and prolongs survival in animal models of cancer.
P5091 plays an important role in ovarian cancer, as it can prevent the growth of cells and can promote necrosis and apoptosis.

Nutrient surplus and consequent free fatty acid accumulation in the liver cause hepatosteatosis. The exposure of free fatty acids to cultured hepatocyte and hepatocellular carcinoma cell lines induces cellular stress, organelle adaptation, and subsequent cell death. Despite many studies, the

The assembly and activation of the inflammasomes are tightly regulated by post-translational modifications, including ubiquitin. Deubiquitinases (DUBs) counteract the addition of ubiquitin and are essential regulators of immune signalling pathways, including those acting on the inflammasome. How DUBs control the
