Alomone Labs NS-3623 reversibly enhances KV11.1 (hERG) channels heterologously expressed in HEK-293 cells. - A. Time course of the reversible enhancing effect of 100 MNS-3623(#N-190) on hERG currents elicited by a 250 ms voltage step from the holding potential of -100 mV to 40 mV followed by a 250 ms step to -20 mV applied every 10 s. Current amplitude was measured at the end of the pulse to -20 mV (see large outward tail in B). B. Superimposed traces of channel activity before and during applications of the indicated NS-3623 concentrations (taken from the experiment shown in panel A).

Alomone Labs Pyrrolopyrimidine 48 blocks NaV1.7 channels expressed in Xenopus oocytes. - A. Time course of NaV1.7 current amplitude and inhibition by 1 and 10 M Pyrrolopyrimidine 48 (#P-275). Currents were elicited by application of a 20 ms voltage step to 0 mV (H.P= -100 mV) every 10 seconds. B. Superimposed example traces of current responses before and during perfusion of 1 and 10 M Pyrrolopyrimidine 48 as indicated.

Product Page - Scientific background :

The hERG (KV11.1) potassium channel underlies the rapid delayed rectifier current, IKr, which is a major determinant of cardiac repolarization1. IKr strongly modulates action potential duration (APD) and the QT interval at the cellular and organ levels, respectively. Loss of function mutations in hERG results in altered channel gating or impaired intracellular trafficking and reduced cell surface expression. These molecular defects give rise to a congenital form of the long-QT Syndrome type 2 (LQT2) and its associated arrhythmia, torsade de pointes (TdP)2. Recent studies have focused on the use of hERG channel agonists, such as NS-3623, as potential drug candidates for the treatment of cardiac arrhythmic disorders 3. The molecular mechanism of action NS-3623 is to primarily activate the native HERG channels underlying the IKr of the cardiomyocytes with an EC50 value of 10.5 μM4.
