WebAbstract—The human ether-a-go-go–related gene (HERG) encodes a K + channel with biophysical properties nearly identical to the rapid component of the cardiac delayed rectifier K + current (I Kr).HERG/I Kr channels are a prime target for the pharmacological management of arrhythmias and are selectively blocked by class III antiarrhythmic … E-4031 acts on a specific class of voltage-gated potassium channels mainly found in the heart, the hERG channels. hERG channels (Kv11.1) mediate the IKr current, which repolarizes the myocardial cells. The hERG channel is encoded by ether-a-go-go related gene (hERG). See more E-4031 is an experimental class III antiarrhythmic drug that blocks potassium channels of the hERG-type. See more E-4031 is a synthesized toxin that is a methanesulfonanilide class III antiarrhythmic drug. See more As E-4031 can prolong the QT-interval, it can cause lethal arrhythmias. See more E-4031 is solely used for research purposes. So far, one clinical trial has been conducted to test the effect of E-4031 on prolongation of the QT-interval. See more E-4031 blocks hERG-type potassium channels by binding to the open channels. Its structural target within the hERG-channel is unclear, but some other methanesulfonanilide class III antiarrhythmic drugs are known to bind to the S6 domain or See more however slownik
