≥5mg/ml Taking the 1 mL working solution as an example, add 5 mg of this product to 1 ml of CMC-Na solution, mix evenly to obtain a homogeneous suspension with a final concentration of 5 mg/ml.
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

生物活性

製品説明 Indacaterol (QAB149) is an ultra-long-acting β-adrenoceptor agonist with pKi of 7.36 for β1-adrenoceptor and pKi of 5.48 for β2-adrenoceptor.
in vitro Indacaterol induces cAMP production in Chinese hamster ovary cells stably transfected with human β2 adrenoceptors. It inhibits electrically induced contraction on the electrically stimulated guinea pig trachea in a concentration-dependent manner with pEC50 of 8.23. Indacaterol induces a concentration-dependent inotropic effect with maximal efficacy of 75% in the isolated guinea pig left atrium. [1] Indacaterol reverses the carbachol-induced contraction in a concentration-dependent manner with IC50 of 37 nM in human small airways. Indacaterol concentration dependently reverses the serotonin-induced contraction with IC50 of 10.5 nM in rat small airways. Indacaterol has the highest intrinsic efficacy of 53% in rat small airways and 73% in human small airways. [2] Indacaterol (10 μM) induces close to full inhibition of the EFS-induced contraction of isolated human bronchi and the effect lasts 12 hours. [3] Indacaterol inhibits the IgE-dependent release of histamine from mast cells with the intrinsic activity (Emax of a long-acting Indacaterol/Emax of Isoprenaline) of 1.03. [4] Indacaterol induces cAMP production from human airway smooth muscle with pEC50 of 8.53 and Emax of 48%. Indacaterol appears to have a reduced efficacy compared with the CHO-K1 data in the primary ASM cells. [5]
in vivo Indacaterol (6.7 μg/kg) inhibits 5-HT-induced bronchoconstriction with a maximal effect of 85% in the conscious guinea pig. Indacaterol (12.5 μg/kg) dose-dependently inhibits methacholine-induced bronchoconstriction with a maximal effect of 85% in the anesthetized rhesus monkey. [1]
