Carmoterol

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).
