| Hazard Information | Back Directory | [Uses]
Vilanterol (GW642444) is a long-acting β2-adrenoceptor (β2-AR) agonist with 24 h activity. The pEC50s for β2-AR,β1-AR and β3-AR is 10.37±0.05, 6.98±0.03 and 7.36±0.03, respectively. | [Definition]
ChEBI: An dichlorobenzene derivative that is used in the form of its trifenate salt for treatment of chronic obstructive pulmonary disease. | [Biological Activity]
vilanterol is a novel and selective agonist of β2-ar with a pec50 value of 10.37±0.05 [1].vilanterol is a novel long-acting β2-ar agonist (laba) with 24h activity in development for inhaled once daily treatment. in the radioligand binding studies, vilanterol has shown the binding affinity in the one-affinity site model with pkd values of 9.44±0.07 and 10.82±0.12 in the presence gpp(nh)p and absence gpp(nh)p, respectively. in dissociation studies, vilanterol has been reported to bind from the β2-ar with a dissociation t1/2 value of 3.5 min in the presence of gpp(nh)p. vilanterol has been found to have a good selectivity for β2-ar over the other β-ar receptor subtypes(β1and β3) with pec50 values of 10.37±0.05, 6.98±0.03 and 7.36±0.03, respectively. vilanterol has exhibited at least 1000-fold selectivity over both β1-and β3-ar subtypes [1]. | [IC 50]
