| 产品描述: | 基本信息 产品编号: R10312 产品名称: Ro 363 CAS: 74513-77-2 储存条件 粉末 -20℃ 四年 分子式: C19H25NO6 溶于液体 -80℃ 二年 分子量: 363.40 化学名: 1,2-Benzenediol,4-[3-[[2-(3,4-dimethoxyphenyl)ethyl]amino]-2-hydroxypropoxy]- 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。 生物活性 产品描述 一种有效且高度选择性的 β1 肾上腺素受体 (β1-adrenoceptor) 激动剂。RO 363 是一种有效的正性肌力活化剂,并且是一种心血管调节剂,可降低舒张压并显着增加心肌收缩力。 靶点 β1-adrenoceptor 体外研究 Isolated perfused heart preparations from guinea-pigs developed arrhythmic contractions following the administration of Ro 363 in doses producing 70-100% of its maximal chronotropic responses.In spontaneously contracted tracheal preparations from the guinea-pig,RO 363 is a full agonist and is approximately half as potent as (-)-Isoprenaline.These effects of RO 363 are due to the activation of a population of β1-receptors in the tissue since RO 363 and (-)-Isoprenaline have the same relative potencies in trachea, cardiac and ileal preparations. 体内研究 In chloralose-anaesthetized cats,Ro 363,when compared to epinephrine (adrenaline),is essentially devoid of arrhythmogenic activity in animals in which cardiac sensitization is induced by U-0882 or halothane. |
