• 产品描述： E-4031 is a selective hERG potassium channel blocker for use in class III anti-arrhythmic studies

• 靶点： Potassium Channel;EGFR; PotassiumChannel

• 体外研究：
  E-4031 (0.1-10 μM) significantly depolarises the maximum diastolic potential (MDP) and prolongs the action charge that depolarises MDP from -58.8+0.9 to -24.5±1.8 mV at 1 μM and from -58.2±2.1 to -19.6±1.8 mV at 10 μM in single SAN cells of New Zealand albinc rabbits. E-4031 (0.1-10 μM) can block part of the outward current during the depolarisation step as well as the tail current (ITD) during subsequent repolarization in a dose-dependent manner, and depresses ITD by 88 % at 10 μM in single SAN cells of New Zealand albinc rabbits

• 体内研究：
  E-4031 (i.v., 50 μg/kg) reduces the net outward current of ventricular myocytes, prolongs the QT interval and activation-recovery interval (ARI) in all left ventricular (LV) layers, and increases transmural ARI dispersion in beagles
