Taking the 1 mL working solution as an example, add 50 μL of 200 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to make it clear; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results.

* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description

GSK2795039 is an inhibitor of NADPH oxidase 2 (NOX2) with pIC50 of 6.57 for NOX2-mediated activation of HRP/Amplex Red. GSK2795039 inhibits reactive oxygen species (ROS) production, NADPH consumption and reduces apoptosis.

Targets

ROS ^[2]	NADPH ^[2]	NOX2 (HRP/Amplex Red) ^[1] (Cell-based assay)
		6.57(pIC50)

In vitro

GSK2795039 inhibits both the formation of ROS and the utilization of the enzyme substrates, NADPH and oxygen, in a variety of semirecombinant cell-free and cell-based NOX2 assays. GSK2795039 inhibits NOX2 in an NADPH competitive manner and is selective over other NOX isoforms, xanthine oxidase, and endothelial nitric oxide synthase enzymes.^[1]

In vivo

Following systemic administration in mice, GSK2795039 abolishes the production of ROS by activated NOX2 enzyme in a paw inflammation model. GSK2795039 shows activity in a murine model of acute pancreatitis, reducing the levels of serum amylase triggered by systemic injection of cerulein.^[1]

Cell Assay:^{^[1]}	Cell lines NOX isoform-specific cells, PBMCs, PMNs, HL60 cells Concentrations 3.16 nM, 10 nM, 31.6 nM, 100 nM, 316 nM, 1μM, 3.16 μM, 10 μM, 31.6 μM, 100μM Incubation Time 10 min, 20 min, 30 min, 40 min, 50 min, 60 min Method For Amplex Red/HRP assay, cells are preincubated with the GSK2795039 for 10 min at room temperature in PerkinElmer black 96-well microplates at 50,000 cells per well, after which the reaction mixture is added to a final concentration of 25 μM of Amplex Red and 0.05 U/ml of HRP in HBSS. NOX enzymes are activated via 100 nM PMA (NOX1, NOX2), 1 μg/ml tetracycline for 24-h activation of inducible genes (NOX3, NOX4), and 1 μM Ca²⁺ ionophore ionomycin (NOX5).
