Carmoterol
Based on 1 Customer Validation
Carmoterol is a highly potent and selective long-acting β2-adrenergic receptor agonist with a pEC50 of 10.19. Carmoterol shows 53-fold higher affinity for β2-adrenergic receptors than for β1-adrenergic receptors. Carmoterol stimulates cyclic adenosine monophosphate accumulation, induces airway smooth muscle relaxation, inhibits bronchoconstriction, reduces thromboxane B2 release, and prolongs survival time. Carmoterol can be used in research related to asthma and chronic obstructive pulmonary disease (COPD).

Biological Activity
Carmoterol exhibits rapid-onset and long-acting bronchodilatory effects, and its potency is superior to that of other long-acting β2-adrenergic receptor agonists in the guinea pig bronchoconstriction model[2].
Carmoterol (0.3-100 pmol; intratracheal instillation; 5 min) dose-dependently inhibits acetylcholine-induced bronchoconstriction in normal guinea pigs, with an ED50 of 16.7 pmol[3].
Carmoterol (0.1-30 pmol; intratracheal instillation; 5 min) potently and dose-dependently inhibits histamine-induced bronchoconstriction (ED50 = 2.7 pmol) and reduces histamine-induced TXB2 release (ED50 = 8.8 pmol) in normal guinea pigs[3].
Carmoterol (0.3-30 pmol; intratracheal instillation; 5 min) dose-dependently inhibits ovalbumin-induced allergic bronchoconstriction (ED50 = 9.5 pmol), reduces TXB2 release (ED50 = 11.8 pmol), and provides complete survival protection in sensitized guinea pigs at doses ≥ 3 pmol[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Reduced ITP elevation to 33.2% of maximal overflow and TXB2 levels to 4.06 ng/mL at 1 pmol.
