| Hazard Information | Back Directory | [Description]
E-4031 (113558-89-7) is a selective hERG potassium channel blocker. Inhibits the rapid delayed-rectifier K+ current (IKr). Class III antiarrhythmic agent. Cell permeable. | [Definition]
ChEBI: E-4031 is a sulfonamide. | [in vitro]
it has been reported that e-4031 could induce eads or tdp, and such induction correlated with a significant increase in variability of repolarization. in addition, e-4031 at 0.1 um was able to significantly prolong cycle length, action potential duration, and depolarized maximum diastolic potential. e-4031could also reduce the upstroke velocity of the action potential as well as the diastolic depolarization rate [1]. | [in vivo]
animal study showed that e-4031 at 0.01 and 0.1 mg/kg could provide effective in-vitro plasma concentrations to significantly inhibit ikr and thus delayed the repolarization beyond the initiation of diastole, leading to the inversion of electro-mechanical coupling, which provides an ideal proarrhythmic substrate [2]. another sutdy found that e-4031 could prolong qt interval and ari in all lv layers, though the magnitude of prolongation was greatest in mid, particularly during bradycardia [3]. | [IC 50]
