| Description | Zileuton sodium is a selective and reversible 5-lipoxygenase (5-LOX) inhibitor that suppresses LTB4 synthesis. It significantly reduces arachidonic acid-induced ear edema in mice (ED50 = 31 mg/kg) and is suitable for inflammation research. |
| In vitro | Zileuton sodium inhibits 5-hydroxydocosahexaenoic acid synthesis in rat basophilic leukemia cell 20,000 x g supernatant and rat polymorphonuclear leukocytes (PMNL), with IC50 = 0.5/0.3 mM. It inhibits leukotriene (LT) B4 synthesis in rat PMNL (IC50 = 0.4 μM), human PMNL (IC50 = 0.4 μM), and human whole blood (IC50 = 0.9 μM). Inhibition of human PMNL LTB4 biosynthesis is readily reversed by simple washing procedures [1]. |
| In vivo | Zileuton sodium (1200 mg/kg) inhibited polyp formation in the colon and small intestine of APCΔ468 rats. Zileuton sodium treatment suppressed proliferation rates of non-epithelial cells within polyps and increased apoptosis within polyps, contributing to reduced polyp incidence in the small intestine and colon of Zileuton sodium-fed APCΔ468 mice [4]. |
