Montelukast sodium  (Synonyms: MK0476)

Cat. No.: HY-13315 Purity: 99.52%
COA Handling Instructions

Montelukast sodium (MK0476) is a potent, selective and orally active antagonist of cysteinyl leukotriene receptor 1 (CysLT1). Montelukast sodium can be used for the reseach of asthma and liver injury. Montelukast sodium also has an antioxidant effect in intestinal ischemia-reperfusion injury, and could reduce cardiac damage. Montelukast sodium decreases eosinophil infiltration into the asthmatic airways. Montelukast sodium can also be used for COVID-19 research.

Description

Montelukast sodium (MK0476) is a potent, selective and orally active antagonist of cysteinyl leukotriene receptor 1 (CysLT1). Montelukast sodium can be used for the reseach of asthma and liver injury. Montelukast sodium also has an antioxidant effect in intestinal ischemia-reperfusion injury, and could reduce cardiac damage. Montelukast sodium decreases eosinophil infiltration into the asthmatic airways. Montelukast sodium can also be used for COVID-19 research[1][2][3][4].

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].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

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.
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].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

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.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
