Zileuton

別名：A-64077

製品コード：S1443 純度：99.98%

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.

製品説明

Targets

Ferroptosis ^[6]

5-lipoxygenase ^[1]

In Vitro
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
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]
