Clear solution
5%DMSO Corn oil
0.65mg/ml Taking the 1 mL working solution as an example, add 50 μL of 13 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. 
* <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 Zileuton is an orally active inhibitor of 5-lipoxygenase, and thus inhibits leukotrienes (LTB4, LTC4, LTD4, and LTE4) formation, used to decrease the symptoms of asthma. Zileuton induces apoptosis while inhibits ferroptosis.
Targets
Ferroptosis [6] 5-lipoxygenase [1]
In vitro

Zileuton suppresses PG biosynthesis by interference with arachidonic acid (AA) release in macrophages. Zileuton significantly reduces PGE2 and 6-keto prostaglandin F1α (PGF1α) levels in activated mouse peritoneal macrophages and in J774 macrophages. Zileuton inhibits PGE2 production in LPS-stimulated human whole blood and suppresses PGE2 and 6-keto PGF1α pleural levels in rat carrageenan-induced pleurisy. [1]

In vivo

Zileuton significantly reduces macroscopic damage score after four weeks of treatment in rats. Zileuton administration significantly increases the intracolonic release of both thromboxane B2 at week 1 and prostaglandin E2 at weeks 2 and 4 in rats. [2] Zileuton reduces the spinal cord inflammation and tissue injury, neutrophil infiltration, TNF-alpha, COX-2 and pERK1/2 expression, PGE(2) and LTB(4) production, and apoptosis in mice. Zileuton significantly improves the recovery of limb function over 10 days in mice.[3]

 

Zileuton administrated before I/R significantly reduces the degree of renal dysfunction (urea, creatinine) and injury (AST, histology) in 5-lipoxygenase knockout mice. Zileuton reduces the expression of ICAM-1 and the associated PMN infiltration caused by I/R of the mouse kidney in 5-lipoxygenase knockout mice. [4]

 

Zileuton inhibits LTB(4) production in the peritonitis model more effectively than the LTA(4)H inhibitor, but the influx of neutrophils into the peritoneum after 1 and 2 hours is significantly higher in Zileuton- versus JNJ-26993135-treated mice. [5]
