isoproterenol hydrochloride

Isoprenaline hydrochloride (Isoproterenol hydrochloride) 是一种 β-肾上腺素能受体激动剂，具有非选择性和口服活性。Isoprenaline hydrochloride 可以扩张支气管，提高心率和心输出量，而不会收缩血管。

(-)-Isoproterenol hydrochloride作为β-adrenergic受体激动剂，在治疗心动过缓和作为支气管扩张剂方面应用。

Bisaramil hydrochloride (Bisaramil) 是一种新型二氮双环壬烷抗心律失常化合物，抑制自由基生成。Bisaramil hydrochloride 可阻断钠电流，抑制异丙肾上腺素在 K（+） 去极化肌上诱导的缓慢 Ca（2+） 动作电位。

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.

Clofeverine hydrochloride is the salt form of Clofeverine (free base), a highly selective relaxant for gastrointestinal smooth muscles with a beta-receptor stimulative nature. On isolated ileum, the inhibitory effect of clofeverine for spontaneous motility was comparable to that of isoproterenol and 100 times higher than that of papaverine.

Protokylol hydrochloride is the salt form of Protokylol (free base) (Asmetil, Caytine, Palison, Ventaire), a β-adrenergic receptor agonist used as a bronchodilator in Europe and the United States. It is methylenedioxyphenyl-isoproterenol.
