Chemical Name: N-[4-[[1-[2-(6-Methyl-2-pyridinyl)ethyl]-4-piperidinyl]carbonyl]phenyl]methanesulfonamide dihydrochloride
Biological ActivitySelective blocker of KV11.1 (hERG) channels; inhibits the rapid delayed-rectifier K+ current (IKr). Reversibly prolongs action potential duration in guinea pig papillary muscle and isolated ventricular myocytes, without affecting Na+ or Ca2+ inward currents. Class III antiarrhythmic agent.

A representative action potential of a guinea pig cardiomyocyte before and after perfusion with 500 nM E-4031 for 5 min and stimulated at a frequency of 1 Hz in a whole cell patch clamp model. E-4031 significantly shortened action potential duration of guinea pig ventricular cardiomyocytes.
As an antiarrhythmic drug E-4031 was studied to identify drug effect. Concentration dependent Kv channel blocking and control of release were studied. The compound showed blocking activity which is not dependent on concentration administered and data was reproducible. Great product stability and dissolves nicely.
