Biological Activity

[Description]:

Pilsicainide hydrochloride (SUN-1165) is an orally active sodium channel blocker and potent class Ic antiarrhythmic agent[1][2].

Research Areas >> Cardiovascular Disease

[In Vitro]

Pilsicainide hydrochloride (SUN-1165) (10-200 μg/mL) decreases peak amplitude of the net inward current in a dose-dependent manner with an IC50 of 29.2 ± 22.9 μg/mL in levo-thyroxine (T4)-treated rat atrial cells[1].

[In Vivo]

Pilsicainide hydrochloride (SUN-1165) (2 mg/kg; i.v.; once) decreases the conduction velocity in T4-treated rat atrium by decreasing the Max dV/dt and net inward current[1]. Animal Model: Male Sprague-Dawley (SD) rats weighing from 200 to 220 g, with levo-thyroxine (T4) treatment[1] Dosage: 2 mg/kg Administration: Bolus injection into right external carotid vein within 2 minutes, once Result: Result: the QT interval was significantly elongated at 15 and 60 minutes after administration. P wave and QRS complex durations were significantly shortened. Markedly decreased action potential amplitudes (APA) and Max dV/dt, and significantly lengthened the action potential durations.
