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
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]
Cell Research 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).
In Vivo
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]

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
