Carmoterol_product_DataBase

Bioactivity	Carmoterol is a highly potent, selective and long-acting β2-adrenoceptor agonist with the pEC50 of 10.19. Carmoterol has 53 times higher affinity for the β2-adrenoceptors than for the β1-adrenoceptors[1][2]. Carmoterol can be used for the research of asthma and chronic obstructive pulmonary disease (COPD)[2].
In Vivo	Bronchoconstriction is induced in normal guinea-pigs by intravenous administration of graded doses of Acetylcholine (10, 20 and 40 mg/kg) and Histamine (5, 10 and 20 mg/kg) or in actively sensitized animals by Ovalbumin (5 mg/kg). Carmoterol (from 0.3 to 100 pmol) is given by superfusion onto the tracheal mucosa for 5 min before challenge. Carmoterol causes a dose-dependent inhibition of the acetylcholine-induced bronchoconstriction with the ED50 of 16.7 pmol[2]. Animal Model:
