(R)-Propranolol hydrochloride

产品介绍 (R)-Propranolol hydrochloride 是抗肾上腺素受体 (β-adrenoceptor) 拮抗剂普萘洛尔 (HY-B0573) 的活性较低的对映体。Propranolol 是一种非选择性的 β-adrenergic receptor (βAR) 拮抗剂,对 β1AR 和 β2AR 具有高亲和力,Ki 值分别为 1.8 nM 和 0.8 nM。
生物活性

(R)-Propranolol hydrochloride is a less active enantiomer of the β-adrenoceptor antagonist propranolol (HY-B0573). Propranolol is a nonselective β-adrenergic receptor (βAR) antagonist, has high affinity for the β1AR and β2AR with Ki values of 1.8 nM and 0.8 nM, respectively.

体外研究
体内研究

Both isomers of propranolol are capable of preventing adrenaline-induced cardiac arrhythmias in cats anaesthetized with halothane, but the mean dose of (-)-propranolol is 0.09 mg/kg whereas that of (+)-propranolol is 4.2 mg/kg.
Both isomers of propranolol are capable of reversing ventricular tachycardia caused by ouabain in anaesthetized cats and dogs. The dose of (-)-propranolol is significantly smaller than that of (+)-propranolol ((R)-Propranolol) in both species.
(R)-Propranolol hydrochloride (10 mg/kg) has no antagonistic activity in rats, the cardiac responses to isoprenaline of rat can be blocked by probably much less than 1/100th of that of the (-) isomer in this preparation.

西域 has not independently confirmed the accuracy of these methods. They are for reference only.
