产品描述 | Impromidine hydrochloride is a very potent and specific histamine H2 receptor agonist for conducting cardiovascular studies. |
体外活性 | Impromidine hydrochloride (1 X 10(-4) M; human isolated left ventricular) inhibited maximal responses to histamine to a level equal to the maximal Impromidine hydrochloride response; however, Impromidine hydrochloride did not inhibit responses to isoprenaline. Positive inotropic activity and inhibition of maximal responses to histamine occurred over a similar Impromidine hydrochloride concentration range. Impromidine hydrochloride displaced histamine concentration-response curves to the right, whereas mepyramine had no effect on responses to histamine. It is concluded that Impromidine hydrochloride has positive inotropic activity on the human ventricle, that the response is mediated via histamine H2-receptors, and that Impromidine hydrochloride is a partial agonist compared with histamine.[2] |
体内活性 | Impromidine hydrochloride (0.46 to 46 nmol/kg/h; dog; 45-min steps) produced the same maximum stimulation of gastric HCI output, increase of HR, and fall in systolic blood pressure as histamine. Impromidine hydrochloride was 38 times more potent than histamine in the stimulation of acid (ED50 3.8 nmol/kg/h) and 30 times more potent in raising HR (ED50 5.6 vs. 172 nmol/kg.hr). The effects of Impromidine hydrochloride on pepsin secretion were qualitatively and quantitatively similar to those of histamine and other H-2 agonists with weak stimulation at low doses and progressive inhibition with increasing doses of Impromidine hydrochloride. Coupling the results with the known high specificity of Impromidine hydrochloride, gastric acid secretion, chronotropic, and hypotension all seem to be purely H-2-mediated effects of histamine in the intact conscious dog.[1] |

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。
