Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O
5.0mg/ml Taking the 1 mL working solution as an example, add 50 μL of 100 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
Clear solution
5% DMSO 95% Corn oil
0.625mg/ml Taking the 1 mL working solution as an example, add 50 μL of 12.5 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description 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.
Targets
CysLT1 [1]
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. [1]
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. [2]
