应用
E-4031 已用作：
- 人类诱导多能干细胞衍生的心肌细胞（hiPSC-CMs）中的人类ether-a-go-go基因（hERG）阻断剂
- 长QT综合征（LQTS）诱导的多能干细胞（iPSC）胚状体的IKr阻滞剂
- 大鼠心室肌细胞中的IKr阻滞剂
生化/生理作用
E-4031是一种抗心律不齐药物，属于III类。它是一种甲磺酰苯胺化合物，可有效治疗心律不齐并调节心室纤颤。E-4031介导转基因长QT 1型（LQT1）兔的动作电位持续时间（action potential duration ，APD）延长。人类 ether-a-go-go相关基因（hERG）中的异亮氨酸突变消除了其与E-4031的相互作用。
E-4031可选择性封闭hERG K+通道。

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

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 embryonic stem cell (hESC) progenies hold great promise as surrogates for human primary cells, particularly if the latter are not available as in the case of cardiomyocytes. However, high content experimental platforms are lacking that allow the function of
