WebE-4031 is a selective hERG potassium channel blocker for use in class III anti-arrhythmic studies [1] . E-4031 (0.1-10 μM) significantly depolarises the maximum diastolic potential (MDP) and prolongs the action charge that … WebHERG contributed current throughout the return of the membrane to the resting potential, and deactivation of HERG current could participate in phase 4 depolarization. HERG current was blocked by low concentrations of E-4031 (IC50 7.7 nM), a value close to that reported for I(Kr) in native cardiac myocytes.
