产品介绍

生物活性
产品描述
Quinidine Monosulfate is an antiarrhythmic agent. Quinidine Monosulfate is a potent, orally active, selective cytochrome P450db inhibitor. Quinidine Monosulfate is also a K + channel blocker with an IC 50 of 19.9 μM. Quinidine Monosulfate can be used for malaria research [1] [2] [3].
体外活性
Quinidine is an anti-arrythmic drug which affects ionic currents in heart muscle and which has also been shown to be a potent blocker of several classes of K + channel in a variety of cell types [1]. Bath application of quinidine causes a dose-dependent reduction of the peak amplitude of I k. The K d for blockade of I k at 0 mV is estimated to be 41 μM [1]. Quinidine elicits a dose-dependent increase of the rate of the decay of I k and this effect is enhanced by membrane depolarization. Quinidine also causes a 5 mV hyperpolarizing shift of the steady-state inactivation curve and increases the half-time for recovery from inactivation. Quinidine does not affect the onset of inactivation measured at -30 mV [1].
体内活性
Quinidine sulfate is rapidly absorbed, with peak plasma concentrations 60-90 min after an oral dose. Other salts (gluconate, polygalacturonate) are more slowly absorbed, with lower peak concentrations [2]. Quinidine is approximately 70-90 % bound to plasma proteins. It undergoes hepatic oxidative metabolism to form an N-oxide, a 3-hydroxy form, an O-demethyl form and 2'-quinidinone. Over one-half of patients starting quinidine stop within the first year of therapy because of side effects. These include, commonly, diarrhea, nausea, and vomiting which are not necessarily related to high plasma concentrations [2]. Quinidine inhibits metabolism of amphetamine in rats. Quinidine pretreatment results in a significant decrease in the excretion of p-hydroxyamphetamine at 24 and 48 h to 7.2 and 24.1% of the vehicle-control levels, respectively, accompanied by a significant increase in amphetamine excretion between 24 and 48 h to 542% of the control [3].

体内实验配液计算器

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:
TargetMol | Animal experiments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 μLTargetMol | Animal experiments 一共给药动物 10 只 ,您使用的配方为 5% TargetMol | reagent 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 μLDMSOTargetMol | reagent ( 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:50μLDMSOTargetMol | reagent 母液,添加 300 μLPEG300TargetMol | reagent 混匀澄清,再加 50μLTween 80, 混匀澄清,再加 600μLddH2OTargetMol | reagent 混匀澄清

以上为“体内实验配液计算器”的使用方法举例,并不是具体某个化合物的推荐配制方式,请根据您的实验动物和给药方式选择适当的溶解方案。
