BeschreibungZileuton is a reversible 5-lipoxygenase (5-LO) inhibitor. It inhibits 5-LO activity in rat basophilic leukemia-1 (RBL-1) cell supernatant with an IC50 value of 0.5 μM. Zileuton inhibits leukotriene B4 (LTB4; ) production induced by the calcium ionophore A23187 in purified human peripheral blood polymorphonuclear leukocytes (PMNLs; IC50 = 0.6 μM). Zileuton (10 mg/kg, p.o.) prevents antigen challenge-induced increases in specific lung resistance in a sheep model of asthma at 4 to 8 hours post-challenge following administration 2 hours pre-challenge. Formulations containing zileuton have been used in the prophylaxis and chronic treatment of asthma.

DefinitionChEBI: A member of the class of 1-benzothiophenes that is 1-benzothiophene in which the hydrogen at position 2 is replaced by a 1-[carbamoyl(hydroxy)amino]ethyl group. A selective 5-lipoxygenase inhibitor, it inhibits the formation of leukotrienes LTB4, LTC4, LDT , and LTE4. It is used for the management of chronic asthma.
