(S)-Gallopamil hydrochloride

(-)-Gallopamil (hydrochloride) exerts a selective modulation of the fast voltage-dependent inactivation. (-)-Gallopamil (hydrochloride) inhibits efficiently Cav1.2 constructs formed by β-subunits (promoting fast voltage-dependent inactivation). (-)-Gallopamil (hydrochloride) also accelerates the voltage-dependent phase of ICa decay (as well as the voltage-dependent decay of Ba2+ currents). (-)-Gallopamil (hydrochloride) is promising for research of antiarrhythmics[1][2].
