Clenbuterol

DB01407ApprovedInvestigationalVet approvedSmall molecule

Clenbuterol is a decongestant and bronchodilator used in a variety of respiratory conditions. A substituted phenylaminoethanol that has beta-2 adrenomimetic properties at very low doses.

Mechanism: Clenbuterol is a Beta(2) agonist similar in some structural respects to salbutamol. Agonism of the beta(2) receptor stimulates adenylyl cyclase activity which ultimately leads to downstream effects of smooth muscle relaxation in the bronchioles.
