产品描述 | Dehydroemetine is an effective antigenic insecticide, which is a synthetic analogue of Emetine dihydrochloride. It can be used to prevent and treat amoeba infections and diseases. It has the effect of treating leishmania infection with skin damage and resistance to metronidazole amoebiosis. |
体内活性 | The mechanism of the inhibitory effect of Dehydroemetine on the heart was investigated using (a) the spontaneously contracting isolated guinea-pig atrial preparation and (b), the electrically driven left atrial preparation. Dehydroemetine decreased the rate and amplitude of contraction of spontaneously contracting atria. Increasing the calcium concentration of the bath fluid to 28.2 mM abolished the effect of Dehydroemetine on the amplitude of contraction while the effect on the rate persisted. Pretreatment with Dehydroemetine increased the capacity of ouabain to induce arrhythmias in spontaneously contracting atria. Similarly, pretreatment with ouabain augmented the inhibitory effect of Dehydroemetine on spontaneous atrial activity. In the electrically driven left atrial preparation, Dehydroemetine caused a decrease in contractile strength which was opposed by ouabain and by increased calcium concentration of the bath fluid. The effect of Dehydroemetine on spontaneously contracting and on electrically driven atria was mimicked by adding excess potassium to the bath fluid. It was concluded that the effects of Dehydroemetine on rate and contractility are, to a large extent, independent of one another. The effect on spontaneous rate is consistent with alteration of the potassium permeability of the myocardial cell membrane while the effect on contractility appears to be due to a decrease in the uptake of calcium from the medium by the myocardial cell.[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。
