| 产品描述: | 基本信息 产品编号: P10984 产品名称: (R)-Propranolol hydrochloride CAS: 13071-11-9 储存条件 粉末 -20℃ 四年 分子式: C16H22ClNO2 溶于液体 -80℃(密封储存) 6个月 分子量: 295.80 -20℃(密封储存) 1个月 化学名: (2R)-1-naphthalen-1-yloxy-3-(propan-2-ylamino)propan-2-ol hydrochloride Solubility (25°C): 体外: DMSO Ethanol Water 体内(现配现用): <1mg/ml表示微溶或不溶。 普西唐提供的所有化合物浓度为内部测试所得,实际溶液度可能与公布值有所偏差,属于正常的批间细微差异现象。 请根据产品在不同溶剂中的溶解度选择合适的溶剂配制储备液;⼀旦配成溶液,请分装保存,避免反复冻融造成的产品失效。 制备储备液 浓度 溶液体积 质量 1mg 5mg 10mg 1mM 3.3807mL 16.9033mL 33.8066mL 5mM 0.6761mL 3.3807mL 6.7613mL 10mM 0.3381mL 1.6903mL 3.3807mL 生物活性 产品描述 抗肾上腺素受体 (β-adrenoceptor) 拮抗剂普萘洛尔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 1.8nM 和 0.8nM。 靶点 Adrenergic Receptor 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 0.09mg/kg whereas that of (+)-propranolol is 4.2mg/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 (10mg/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. |
