Biological Activity

Description

GSK484 HCl, a benzoimidazole derivative, is a selective and reversible inhibitor of peptidylarginine deiminase 4 (PAD4) with IC50 of 50 nM in the absence of Calcium.

Targets

PAD4 ^[1]
(in the absence of Calcium)

50 nM

In vitro

GSK484 also inhibits PAD4 citrullination (at 0.2 mM calcium) of benzoyl-arginine ethyl ester (BAEE) substrate in a concentration-dependent manner, as detected using an NH3 release assay. GSK484 causes a clear, statistically-significant reduction in diffused NETs.^[1]

In vivo

GSK484 prevents tumor-induced NETosis in vivo and can antagonize kidney injury in mice with mammary carcinoma or pancreatic neuroendocrine tumors.^[2]

Cell Assay:^{^[1]}	Cell lines NB4 cells, HEK293 cells Concentrations 10 μM, 100 μM Incubation Time 20 min Method HEK293 cells stably expressing N-terminal FLAG-tagged PAD1, PAD2, PAD3 or PAD4 are engineered by retroviral transduction. Cells are grown in 15 cm diameter plates to subconfluency in DMEM supplemented with 10% Foetal Bovine Serum, harvested by centrifugation and washed once in PBS/2 mM EGTA. Cells are lysed in 50 mM Tris-Cl, pH 7.4, 1.5 mM MgCl₂, 5% glycerol, 150 mM NaCl, 25 mM NaF, 1 mM Na₃VO₄, 0.4% NP40, 1 mM DTT with protease inhibitors. Lysates are pre-incubated for 20 min at 4℃ with DMSO alone (2%) or 100 μM of GSK484. Citrullination reactions are performed for 30 min at 37℃ in the presence of 2 mM calcium.
