(s) isoproterenol bitartrate

(S)-Isoproterenol bitartrate is a bioactive chemical.

Isoproterenol bitartrate is a beta-sympathomimetic and an isopropyl analog of Epinephrine, which acts on the heart, bronchi, skeletal muscle, and alimentary tract. It is used mainly as a bronchodilator and heart stimulant.

Isoproterenol-d7 is intended for use as an internal standard for the quantification of isoproterenol by GC- or LC-MS. Isoproterenol is an agonist of β1- and β2-adrenergic receptors (β1- and β2-ARs; Kis = 224 and 458 nM, respectively). It is selective for β1- and β2-ARs over β3-ARs (Ki = 1,570 nM). Isoproterenol inhibits contractions in isolated field-stimulated rat vas deferens (EC50 = 45.6 nM). In vivo, isoproterenol (0.33 mg/kg) decreases blood pressure and increases water intake in nephrectomized rats. It reduces blood pressure and increases heart rate in renal hypertensive rabbits. Isoproterenol inhibits histamine-induced bronchospasms in anesthetized dogs. Formulations containing isoproterenol have been used in the treatment of bradydysrhythmias and to improve breathing during anesthesia.

Isoproterenol sulfate anhydrous is a useful alkaloid. It is used for biological research.

(-)-Isoproterenol hydrochloride is used as a β-adrenergic receptor agonist in the treatment of bradycardia and as a bronchodilator.

Isoprenaline (Norisodrine) is a non-selective and orally active β-adrenoceptor agonist.Isoproterenol is a potent peripheral vasodilator and bronchodilator.Isoproterenol can be used in the study of bradycardia and bronchial asthma for the treatment of heart block, bradycardia.

Isoproterenol tartrate, (-)- is a beta-Adrenoceptor agonist agent that increases cytosolic cAMP.
