MedKoo CAT#: 531006

CAS#: 121-54-0 (Cl-)

Description: Benzethonium Chloride, also known as Hyamine, is synthetic quaternary ammonium salt that has surfactant, antiseptic, and anti-infective properties. Benzethonium Chloride is commonly used as a topical antimicrobial agent. Benzethonium chloride exhibited concentration-dependent inhibitions of HERG channel currents with IC(50) values of 4nM and 17nM, respectively, which were also voltage-dependent and use-dependent. Benzethonium Chloride shifted the channel activation I-V curves in a hyperpolarized direction for 10-15mV and accelerated channel activation and inactivation processes by 2-fold.
