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.
1 Customer Review
CD19+ B cells (A) or PBMCs (B) from a healthy donor were treated with zileuton (10 μM) prior to 17-HDHA or RvD1 treatment, followed by stimulation with the IgE-inducing cocktail. Cell culture supernatants were collected at day 7, and IgE levels were measured. The experiment was done in one representative donor (mean ± SEM). Data were analyzed by 1-way ANOVA with Tukey’s post test, **P ≤ 0.01, ***P ≤ 0.001. PBMC, peripheral blood mononuclear cell.
JCI Insight, 2017, 2(3):e88588. Zileuton purchased from Selleck.

|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 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. 
|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.  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. 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.  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. |

* 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.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (g) = Concentration (mol/L) × Volume (L) × 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.
