WebJan 7, 2024 · The hERG gene was originally isolated and identified from the human hippocampal cDNA library in 1994 by Warmke et al. [2], which has homology with the Drosophila EAG gene. The hERG gene is located on human chromosome 7 (7q35～q36), about 55kb, has 16 exons, and encodes 1159 amino acid residues. 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
