Biochem/physiol Actions

Vernakalant is a multiple ion channel blocker that exerts in vivo anti-fibrillatory (anti-arrhythmic) efficacy (ED50 = 1.5 μmol/kg/min iv. against ischemia-induced arrhythmias in rats) via atrial-selective Kv1.5 blockage (hKv1.5/rKv4.2/rKv4.3 IC50 = 13/38/30 μM at 1Hz & -80 to 60 mV in 200 (Kv1.5) or 400 (Kv4) msec) as well as potential- and rate-dependent Nav1.5 blockade (inward Na current INa IC50 = 9 μM/20 Hz & -80 mV, 31 μM/1Hz & -60 mV, 107 μM/1Hz & -120 mV using HEK hNav1.5 cells).

Evidence has emerged that small-conductance Ca2+-activated K+ (SK) channels constitute a new target for treatment of atrial fibrillation (AF). SK channels are predominantly expressed in the atria as compared with the ventricles. Various marketed antiarrhythmic drugs are limited by ventricular

The antiarrhythmic drug vernakalant exerts antiarrhythmic effects in atrial fibrillation. Recent experimental data suggest interactions with the late sodium current and antiarrhythmic effects in ventricular arrhythmias. We aimed at investigating whether treatment with vernakalant reduces polymorphic ventricular tachycardia (VT) in

Ranolazine has been reported to have an antiarrhythmic potential. The aim of this study was to assess the electrophysiologic effects of ranolazine and to compare its effects to vernakalant in an experimental whole-heart model of short-QT syndrome. Rabbit hearts were

Vernakalant inhibits several potassium currents and causes a rate- and voltage-dependent inhibition of the sodium current. The aim of this study was to evaluate the antiarrhythmic mechanism of vernakalant in normal and electrically remodeled atria. Fourteen goats were instrumented with

Molecular dynamics simulations are employed to determine the inhibitory mechanisms of three drugs, 5-(4-phenoxybutoxy)psoralen (PAP-1), vernakalant, and flecainide, on the voltage-gated K+ channel Kv1.5, a target for the treatment of cardiac arrhythmia. At neutral pH, PAP-1 is neutral, whereas the
