产品描述 | (R)-Propranolol hydrochloride (Dexpropranolol hydrochloride) is the less active enantiomer of the anti-adrenoceptor (β-adrenoceptor) antagonist propranolol. Propranolol is a nonselective β-adrenergic receptor (βAR) antagonist with a high affinity for β1AR and β2AR with Ki values of 1.8 nM and 0.8 nM, respectively. |
靶点活性 | β2-adrenoceptor:0.8 nM(Ki), β1-adrenoceptor:1.8 nM(Ki) |
体内活性 | Both isomers of propranolol are capable of preventing adrenaline-induced cardiac arrhythmias in cats anaesthetized with halothane and reversing ventricular tachycardia caused by ouabain in anaesthetized cats and dogs, but the dose of (-)-propranolol is significantly smaller than that of (+)-propranolol ((R)-Propranolol) in both species[4]. Administration of 10 mg/kg (R)-Propranolol hydrochloride has no antagonistic activity in rats, the cardiac responses to isoprenaline of rats can be blocked by probably much less than 1/100th of that of the (-) isomer in this preparation[4]. |

请在以下方框中输入您的动物实验信息后点击计算,可以得到母液配置方法和体内配方的制备方法: 比如您的给药剂量是10 mg/kg,每只动物体重20 g,给药体积100 μL,一共给药动物10 只,您使用的配方为5% DMSO+30% PEG300+5% Tween 80+60% ddH2O。那么您的工作液浓度为2 mg/mL。
母液配置方法:2 mg 药物溶于 50 μL DMSO (母液浓度为 40 mg/mL), 如您需要配置的浓度超过该产品的溶解度,请先与我们联系。
体内配方的制备方法:取 50 μL DMSO 主液,加入 300 μL PEG300, 混匀澄清,再加 50 μL Tween 80,混匀澄清,再加 600 μL ddH2O, 混匀澄清。
