| 产品描述 | Aformoterol is the (R,R)-enantiomer of the β2-adrenergic receptor (β2-AR) agonist formoterol . It selectively binds to β1- over β2-ARs (Kds = 2.9 and 113 nM, respectively) as well as β3-adrenergic, B2 bradykinin, neurokinin 1 (NK1) and NK2 receptors when used at concentrations up to 3 μM. Aformoterol induces cAMP accumulation in cultured human bronchial epithelial cells. Ex vivo, aformoterol (0.01-1,000 nM) induces dose-dependent relaxation of guinea pig tracheal strips precontracted with carbamoylcholine , ovalbumin, or histamine (pD2s = 8.4, 9.5, and 9.5, respectively). In vivo, aformoterol reverses histamine- and ovalbumin-induced bronchoconstriction in guinea pigs (ED50s = 1 and 40 nmol/kg, respectively). Formulations containing aformoterol have been used in the treatment of chronic obstructive pulmonary disease (COPD). |
