Description
An adrenergic receptor agonist; selective for β2-ARs over β1-ARs (Kds = 46 and 4,000 pM, respectively); binds more potently to β2-ARs in isolated guinea pig lung than to β1-ARs in isolated guinea pig cardiac ventricle in the presence (IC50s = 175 and 1,660 nM, respectively) and absence of GTP (IC50s = 55.1 and 1,660 nM, respectively); inhibits acetylcholine-induced contractions in isolated guinea pig trachea (EC50 = 10.5 nM); inhibits histamine-induced airflow obstruction in a guinea pig model of ovalbumin-sensitized asthma at 10 μg/ml via inhalation
