kv11.1

NS3623 is an activator of human ether-a-go-go-related gene (hERG) potassium channels with a dual mode of action, also acting as an inhibitor of hERG1 channels. It activates the IKr and Ito currents and exhibits an antiarrhythmic effect.

NS1643 is a potent human ether-a-go-go related gene (hERG) KV11.1 channel activator with EC50 of 10.5 μM.

NS309 is a nonselective activator of small- and intermediate-conductance Ca2+-activated K+ (SK KCa2 and IK KCa3.1) channels (EC50s range from 0.12-1.2 µM for SK channels and 10-90 nM for IK channels). It can also activate voltage-gated Kv11.1 channels (hE

SKF32802 is a novel potent, selective hERG potassium channel (Kv11.1) activator that induces a leftward shift in the voltage dependence of activation.

BeKm-1 TFA is a potent, selective blocker of the KV11.1 (hERG) channel, demonstrating specificity for KV11.1 over 14 other potassium channels. This compound dose-dependently prolongs the QTc interval in isolated rabbit hearts, affirming its role as a selective inhibitor.

Potent and selective KV11.1 (hERG) channel blocker. Selective for KV11.1 over a panel of 14 other potassium channels. Dose-dependently prolongs QTc interval in isolated rabbit heart.
