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可选择性封闭hERG K+通道。
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。
