产品描述 | Diproteverine HCl is a novel calcium antagonist with antianginal properties, antispasmodic and vasoactive. |
体外活性 | Diproteverine (1 μM; sheep Purkinje fibers) to reduce the amplitude of the slow action potential (IC30 = 2 μM) and to shorten the duration of the fast action potential at 50% repolarisation (IC30 = 2.5 μM). Papaverine was found to possess marginal membrane channel-blocking activity and to be much more potent than diproteverine as a cAMP-phosphodiesterase inhibitor (IC50 = 8 μM).[2] |
体内活性 | Diproteverine (0.25-0.75 mg/kg; i.e.; dog; at plasma levels within the assumed therapeutic range) dose-relatedly decreases heart rate, increases corrected sinus node recovery time, and decreases Wenckebach point. These effects are observed at plasma levels ranging between 16.2 +/- 4.1 and 144.7 +/- 12.5 ng/ml. After cholinergic blockade with N-methylscopolammonium, diproteverine lowers heart rate (greater than or equal to 0.25 mg/kg), increases corrected sinus node recovery time, and decreases Wenckebach point (greater than or equal to 0.5 mg/kg). After propranolol, diproteverine only significantly reduces corrected sinus node recovery time 5 min after the third administration (0.75 mg/kg). After pharmacologic autonomic blockade by N-methylscopolammonium propranolol combination, diproteverine lowers the intrinsic heart rate (greater than or equal to 0.25 mg/kg) and Wenckebach point (greater than or equal to 0.5 mg/kg). Diproteverine does not modify mean blood pressure. These results show that diproteverine administered with and without pharmacologic autonomic blockade in the conscious dog causes dose-related depressant effects on sinus node function and atrioventricular conduction without producing significant vasodilatation.[1] |

对于不同动物的给药剂量换算,您也可以参考 更多...
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。
