Vilanterol-d4 (triphenylacetate)

Vilanterol-d4 is intended for use as an internal standard for the quantification of vilanterol (Cay-20702) by GC- or LC-MS. Vilanterol is a long-acting agonist of the beta2-adrenergic receptor (beta2-AR). It selectively induces cAMP accumulation in CHO cells expressing the beta2-AR over the beta1- and beta3-ARs (EC50 = 0.4, 398, and 794 nM for the human receptors, respectively). Vilanterol inhibits contractions induced by electrical stimulation in isolated superfused guinea pig trachea strips. It inhibits bronchospasms induced by histamine (Cay-33828) in guinea pigs when administered via nebulization (EC50 = 30 µM). Formulations containing vilanterol, in combination with fluticasone, have been used in the treatment of chronic obstructive pulmonary disease (COPD) and asthma.Formal Name: alpha1R-[[[6-[2-[(2,6-dichlorophenyl)methoxy]ethoxy-d4]hexyl]amino]methyl]-4-hydroxy-1,3-benzenedimethanol, triphenylacetate.
