产品描述 | PD-118057 is a potent ether associated (hERG) potassium channel activator that shows no activity against hERG. PD-118057 inhibits the excitability of the membrane by activating the hERG channel. PD-118057 is a potential compound for the treatment of delayed repolarization in inherited or acquired long QT syndrome and congestive heart failure. |
体外活性 |
PD-118057 (3 μM and 10 μM) specifically increases hERG current and inhibits action potential duration in guinea pig ventricular muscle in acute isolation of guinea pig cardiomyocytes.[1][2] PD-118057 (10 μM) counteracts the current inhibition triggered by Dof and Mox while preserving the unaltered 'hump' shape of the IKr current and exhibiting only a marginal increase in the maximum value of the suppressed current.[2] |

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。
