Domiphen bromide is a quaternary antiseptic used as an antifungal agent. Domiphen bromide has potent activity on blockade of human ether-a-go-go related gene (HERG) channels. Domiphen bromide inhibited HERG channel currents in a dose-dependent manner with IC50 values of 9nM. Block of HERG channel by domiphen bromide was voltage-dependent and use-dependent. Domiphen bromide caused substantial negative shift of the activation curves, accelerated activated process, but had no effects on the deactivation and reactivation processes.
