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.

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

Human induced pluripotent stem cell (hiPSC)-derived cardiomyocytes hold great potentials to predict pro-arrhythmic risks in preclinical cardiac safety screening, although the hiPSC cardiomyocytes exhibit rather immature functional and structural characteristics, including spontaneous activity. Our physiological characterization and mathematical simulation showed

Missense mutations in KCNH2, a gene encoding the Kv11.1 channel, cause long QT syndrome (LQTS) type 2 primarily by disrupting the intracellular transport of Kv11.1 to the plasma membrane. The present study aimed to clarify the functional changes by two
