Solubility (25°C)* In vitro DMSO 100 mg/mL (129.07 mM)
Ethanol 10 mg/mL (12.9 mM)
Water Insoluble
In vivo (Add solvents to the product individually and in order)
Clear solution
5% DMSO 95% Corn oil
0.5mg/ml Taking the 1 mL working solution as an example, add 50 μL of 10 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. 
Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O
7.5mg/ml Taking the 1 mL working solution as an example, add 50 μL of 150 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. 
* <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 Vilanterol trifenatate (GW642444M) is a novel inhaled long-acting beta2 adrenoceptor agonist with inherent 24-hour activity for once daily treatment of COPD and asthma.
Targets
β2-adrenoceptor [1]
In vitro Vilanterol displays a subnanomolar affinity for the β2-AR that is comparable with that of salmeterol but higher than olodaterol, formoterol, and indacaterol. In cAMP functional activity studies, vilanterol demonstrates similar selectivity as salmeterol for β2- over β1-AR and β3-AR, but a significantly improved selectivity profile than formoterol and indacaterol. Vilanterol also shows a level of intrinsic efficacy that is comparable to indacaterol but significantly greater than that of salmeterol. In cellular cAMP production and tissue-based studies measuring persistence and reassertion, vilanterol has a persistence of action comparable with indacaterol and longer than formoterol. In addition, vilanterol demonstrates reassertion activity in both cell and tissue systems that is comparable with salmeterol and indacaterol but longer than formoterol. In human airways, vilanterol is shown to have a faster onset and longer duration of action than salmeterol, exhibiting a significant level of bronchodilation 22 h after treatment[1].
