Description:

WARNING: This product is for research use only, not for human or veterinary use.

GSK484 is a potent PAD-4 inhibitor (Protein-arginine deiminase type-4). GSK484 potently binds to the low-calcium form of PAD4 in a reversible manner (IC50 of 50 nM) and appears to be competitive with substrate. GSK484’s selectivity for PAD4 over PAD1-3 was shown in cells and also confirmed with recombinant enzymes. This probe is an inhibitor of cellular citrullination in primary neutrophils, and further phenotypic profiling has confirmed its ability to inhibit NET formation in both mouse and human neutrophils. GSK484 exhibits favourable pharmacokinetic profiles, with low-moderate clearance, and good volume of distribution and half-life in mouse and rat, and has suitable a PK profile for use as a potential in vivo tool.

More Info
PAD4 is a calcium-dependent enzyme which catalyses the transformation of protein arginine residues into citrulline, with the release of ammonia. PAD4-dependent citrullination/deimination of histones plays a key role in the histone code and is predicted to manifest with wide-ranging transcriptional and structural functions, including recently-discovered roles in the regulation of stem cell maintenance (1). In addition to a growing rationale in oncology, PAD4 has strong associations with multiple immune and inflammatory processes. For example, in rheumatoid arthritis the enzyme citrullinates joint proteins to break tolerance and provoke autoimmunity, with antibodies against these citrullinated epitopes (and against PAD4 itself) representing a diagnostic hallmark of the disease. In addition, PAD4 is known to promote profound chromatin decondensation during the innate immune response to infection in neutrophils by mediating formation of neutrophil extracellular traps (NETs). This is an enigmatic and exciting field where initially proposed roles for NETs in trapping pathogens for host-defence purposes (2) have been extended to demonstrate that unrestrained NETosis may be crucial for pathological deep venous thrombosis (3) ischemia/reperfusion injury (4), systemic lupus erythematosis (5), small vessel vasculitis (6) and also in rheumatoid arthritis (7).

Biological target:
GSK484 hydrochloride is a selective and reversible peptidylarginine deiminase 4 (PAD4) inhibitor that demonstrates high affinity binding to PAD4 with IC50s of 50 nM in the absence of Calcium.
In vitro activity:
Next, different concentrations of PAD4 inhibitor (GSK484) was used to treat C666-1 and 6-10B cells. The data delineated that GSK484 concentration-dependently decreased the expression of PAD4 (Fig. 3a, b). As shown in Fig. 3b, the survival fraction of NPC cells exposed to irradiation was significantly inhibited after treatment of GSK484 (Fig. 3c). The results from EdU assay showed that treatment of GSK484 suppressed cell proliferation after irradiation (Fig. 3d). Furthermore, analysis of migration and invasion revealed that treatment of GSK484 restrained the migratory and invasive ability of C666-1 cells (Fig. 3e,f). Western blot demonstrated that the citH3 protein levels were markedly reduced by PAD4 inhibition (Fig. 3g). The above findings suggested that GSK484 exerts inhibitory effects on radioresistance and aggressive phenotypes of NPC cells through inhibiting the activity of PAD4. Colony formation assay demonstrated that GSK484 treatment reversed the promotive effect of PAD4 overexpression on the survival fraction of C666-1 cells (Fig. 4c). Moreover, the effects on the increase of aggressive phenotypes of C666-1 cells caused by PAD4 were abrogated after treatment of GSK484 (Fig. 4d, f). Furthermore, in Fig. 4g, citH3 was significantly elevated in PAD4 overexpressed cells but knocked down by GSK484, suggesting that histone citrullination occurs in a PAD4-dependent way. These results suggested the key role of GSK484 in inhibiting the effects of PAD4 on radiosensitivity and malignant phenotype of NPC cells.

In vivo activity:
This experiment explored whether NET release is involved in adhesion formation. GSK484 is a selective and reversible inhibitor of peptidyl arginine deiminase (PAD)-4. GSK484 was administered on day1 and 1 h before cecum cauterization. Mice treated with GSK484 presented with a significant but reduced adhesion score compared to the control mice at day 7 post-operation (Fig. 3A). Given this finding the experiment went on to evaluate if the neutrophils are responsible for these NETs, as similar phenotypes can also be produced by several other cell types, including macrophages. GSK484-treated mice displayed much lower intensities of CitH3 than control mice (Fig. 3B) and there were significantly more neutrophils undergoing NETs (stained in yellow) in the control mice than in the GSK484-treatment group (Fig. 3B). Consistent with this, ImageJ Fiji analysis revealed high correlation coefficient of colocalization between Ly-6G and CitH3 in control mice (Supplementary Fig. 2). In contrast, the correlation coefficient was low in the mice receiving GSK484 (Supplementary Fig. 2). These results suggest that GSK484 treatment protects against adhesions, likely through inhibiting NET release by neutrophils.
