Application

E-4031 has been used as:
  • human ether-a-go-go-related gene (hERG) blocker in human-induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs)
  • IKr blocker in long QT syndrome (LQTS) induced pluripotent stem (iPSCs) embryoid bodies
  • IKr blocker in rat ventricular myocytes

Biochem/physiol Actions

E-4031 is a antiarrhythmic drug and belongs to the class III type. It is a methanesulfonanilide compound and is effective in treating arrhythmia and modulates ventricular fibrillation. E-4031 mediates the prolongation of action potential duration (APD) in transgenic long-QT type 1 (LQT1) rabbits. An isoleucine mutation in human ether-a-go-go-related gene (hERG) abolishes its interaction with E-4031.
E-4031 selectively blocks hERG K+ channels.

Induced pluripotent stem cells (iPSCs) are novel stem cells derived from adult mouse and human tissues by reprogramming. Elucidation of mechanisms and exploration of efficient methods for their differentiation to functional cardiomyocytes are essential for developing cardiac cell models and

Current cardiac drug safety assessments focus on hERG channel block and QT prolongation for evaluating arrhythmic risks, whereas the optogenetic approach focuses on the action potential (AP) waveform generated by a monolayer of human cardiomyocytes beating synchronously, thus assessing the

Long QT syndrome (LQTS) is caused by functional alterations in cardiac ion channels and is associated with prolonged cardiac repolarization time and increased risk of ventricular arrhythmias. Inherited type 2 LQTS (LQT2) and drug-induced LQTS both result from altered function
