产品详情
生物活性:
Disopyramide (Dicorantil) is a class IA antiarrhythmic agent with efficacy in ventricular and atrial arrhythmias. Disopyramide blocks the fast inward sodium current of cardiac muscle and prolongs the duration of cardiac action potentials. Disopyramide inhibits HERG encoded potassium channels. Disopyramide also exhibits complex protein binding, and has a potent negative inotropic action.

体外研究:
HERG tail currents recorded at -40 mV following test pulses to +30 mV were inhibited in a dose-dependent fashion by Disopyramide concentrations within the clinical range (IC50=7.23 μM).
