GKT137831 attenuates hypoxia-induced H(2)O(2) release, cell proliferation, and TGF-β1 expression and blunted reductions in PPARγ in HPAECs and HPASMCs.  GKT137831 also prevents oxidative stress in response to hyperglycemia in human aortic endothelial cells. 
In WT and SOD1mut mice, GKT137831 (60 mg/kg i.g.) blocks liver fibrosis and downregulates markers of oxidative stress, inflammation, and fibrosis.  GKT137831 (60 mg/kg/d p.o.) also attenuates chronic hypoxia–induced right ventricular hypertrophy, vascular remodeling, lung cell proliferation, and hypoxic alterations in lung PPARγ and TGF-β1 expression in mouse model of chronic hypoxia exposure.  In diabetic apolipoprotein E-deficient mice, GKT137831 (60 mg/kg/d p.o.) attenuates diabetes mellitus-accelerated atherosclerosis.  Moreover, in angII-infused c-hNox4Tg mice, GKT137831 abolishes the increase in oxidative stress, suppresses Akt-mTOR and NF-κB signaling pathway and attenuates cardiac remodeling.

|In vitro||DMSO||78 mg/mL warmed (197.54 mM)|
|In vivo||Add solvents to the product individually and in order(Data is from Selleck tests instead of citations):
2% DMSO+2% Tween 80+30% PEG 300+ddH2O
For best results, use promptly after mixing.
* 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.

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.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
