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].

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
