Clear solution
5% DMSO 95% Corn oil
1.55mg/ml Taking the 1 mL working solution as an example, add 50 μL of 31 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results. 
Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O
1.55mg/ml Taking the 1 mL working solution as an example, add 50 μL of 31 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 clarify; 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 Febuxostat (TMX 67, TEI-6720) is a selective xanthine oxidase inhibitor with Ki of 0.6 nM.
Targets
xanthine oxidase [1]
0.6 nM(Ki)
In vitro Febuxostat displays potent mixed-type inhibition of the activity of purified bovine milk xanthine oxidase, with Ki and Ki' values of 0.6 nM and 3.1 nM respectively, indicating inhibition of both the oxidized and reduced forms of xanthine oxidase. [2]
In vivo Febuxostat (5–6 mg/kg/day) combined with fructose significantly lowers blood pressure, UA, triglycerides, and insulin in rats compared with fructose alone. Febuxostat (5–6 mg/kg/day) combined with fructose also reduces glomerular pressure, renal vasoconstriction, and afferent arteriolar area in rats compared with fructose alone. [2] Febuxostat prevents hyperuricemia in 5/6 nephrectomy (5/6 Nx)+oxonic acid (OA)+Febuxostat(Fx) rats and ameliorates proteinuria, preserves renal function and prevents glomerular hypertension in both 5/6 nephrectomy (5/6 Nx)+vehicle (V)+Febuxostat(Fx) and 5/6 nephrectomy (5/6 Nx)+oxonic acid (OA)+Febuxostat(Fx) groups. [3] Febuxostat (5 mg/kg/d by gavage for 8 days) treatment after transverse aortic constriction (TAC) attenuates the TAC-induced left ventricular (LV) hypertrophy and dysfunction. Febuxostat blunts the TAC-induced increases in nitrotyrosine (indicating reduced myocardial oxidative stress), p-Erk(Thr202/Tyr204), and p-mTOR(Ser2488), with no effect on total Erk or total mTOR. [4] Febuxostat significantly suppresses oxonic acid activity, and thereby reduces oxidative stress in Sprague-Dawley rats with right nephrectomy and left renal I/R injury, as assessed by nitrotyrosine, thiobarbituric acid-reactive substances (TBARS) and urine 8-isoprostane. Febuxostat also reduces the induction of endoplasmic reticulum (ER) stress in Sprague-Dawley rats with right nephrectomy and left renal I/R injury, as assessed by GRP-78, ATF4, and CHOP. [5]
