E-4031（Cat No.:113559-13-0） is an antiarrhythmic agent belonging to the benzenesulfonamide class. It functions by blocking the ATP-sensitive potassium channel. By inhibiting this channel, E-4031 disrupts the flow of potassium ions, prolonging the action potential duration in cardiac cells. This property makes it useful in the treatment of certain cardiac arrhythmias. E-4031’s mechanism of action and specific target make it valuable in studying potassium channel function and developing therapeutic interventions for arrhythmias and related cardiovascular disorders.
