Montelukast (MK0476 free base) 是一种有效的、选择性和具有口服活性的半胱氨酸白三烯受体 1 (CysLT1) 拮抗剂。Montelukast 可用于研究预防哮喘和肝损伤。Montelukast 在肠缺血-再灌注损伤中也具有抗氧化作用,还可以减少心脏损伤。Montelukast 减少嗜酸性粒细胞浸润到哮喘气道。Montelukast 也可用于 COVID-19 的研究。
生物活性 | Montelukast (MK0476 free base) is a potent, selective and orally active antagonist ofcysteinylleukotriene receptor1 (CysLT1). Montelukast can be used for the reseach of asthma and liver injury. Montelukast also has an antioxidant effect in intestinal ischemia-reperfusion injury, and could reduce cardiac damage. Montelukast decreases eosinophil infiltration into the asthmatic airways. Montelukast can also be used for COVID-19 research[1][2][3][4]. |
IC50& Target[1] | |
体外研究 (In Vitro) | Montelukast (5 μM; 1 h) inhibits APAP (Acetaminophen) (HY-66005)-induced cell damage[1]. Montelukast (0.01-10 μM; 30 min) diminishes the 5-oxo-ETE–induced cell migration and modulates the activation of the plasmin-plasminogen system[3]. Montelukast (10 μM; 18 h) modulates the activation of MMP-9[3].
Cell Migration Assay[3] Cell Line: | Eosinophils | Concentration: | 0.01-10 μM | Incubation Time: | 30 min | Result: | Diminished the 5-oxo-ETE–induced cell migration. |
Western Blot Analysis[3] Cell Line: | Eosinophils | Concentration: | 10 μM | Incubation Time: | 18 h | Result: | Reduced the 5-oxo-ETE–boosted MMP-9 secretion. |

体内研究 (In Vivo) | Montelukast (3 mg/kg; oral gavage) protects against APAP-induced hepatotoxicity in mice[1]. Montelukast (1 mg/kg; miniosmotic pump administration) reduces the airway remodeling changes observed in OVA-treated mice and blocks the actions of cysteinyl leukotrienes (LT) C4, D4, and E4 mediated by the CysLT1 receptor[2]. Montelukast (1 mg/kg; miniosmotic pump administration) reduces the elevated levels of IL-4 and IL-13 found in the BAL fluid of OVA-treated mice[2].
Animal Model: | C57BL/6J mice (8-week-old; 22-25 g) are induced acute hepatic injury[1] | Dosage: | 3 mg/kg | Administration: | Oral gavage 1 h after saline or APAP administration | Result: | Decreased serum levels of alanine transaminase (ALT) and aspartate aminotransferase (AST), and alleviated liver damage. |
