Montelukast Sodium LTR antagonist

Name: Montelukast Sodium
Brand: Selleck Chemicals
SKU: S4211
Rating: 5 (11 reviews)

Cat. No.: S4211

Montelukast Sodium selectively antagonizes leukotriene D₄ (LTD₄) by binding to it so that block the action of leukotriene D4 on the cysteinyl leukotriene receptor CysLT1. Montelukast improves macroautophagy but not the chaperone-mediated autophagy pathway. Solutions are unstable and should be fresh-prepared.

Mecanismo de acción (Mechanism of Action)

Targets/IC₅₀/Ki	CysLT1
In vitro	Montelukast is a leukotriene receptor antagonist (LTRA) used for the maintenance treatment of asthma and to relieve symptoms of seasonal allergies. Montelukast blocks the action of leukotriene D4 on the cysteinyl leukotriene receptor CysLT1 in the lungs and bronchial tubes by binding to it, preventing airway edema, smooth muscle contraction, and enhanced secretion of thick, viscous mucus. This reduces the bronchoconstriction otherwise caused by the leukotriene, and results in less inflammation.
In vivo	Montelukast (6 mg/kg, once per day for 20 d) significantly suppresses the increased eosinophils in BAL fluid and lung tissue, and increases IL-5 level in BAL fluid in OVA challenged mice. OVA challenge increases CysLT1 but decreases CysLT2 receptor mRNA expression. Montelukast inhibits the increased CysLT1 but not the reduces CysLT2 expression after OVA challenge.
