UniProtKB description: Selective inhibitor of voltage-gated potassium channel Kv10.1/KCNH1/EAG1 (IC(50)=637 nM). It acts by shifting the voltage dependence of channel activation in a depolarising direction. It shows a 100% inhibition at saturating concentrations, shows fast on-rates and is reversible. It also slightly affects channel inactivation, when the membrane is highly depolarised (>+80 mV).
