Eleclazine hydrochloride (GS 6615 hydrochloride) is a novel, highly selective inhibitor of the cardiac late sodium current, with an IC50 value of <1μM[1]. By reducing intracellular sodium and calcium overload, Eleclazine hydrochloride (GS 6615 hydrochloride) stabilizes the cardiac membrane potential and suppresses arrhythmias, and is commonly used in the treatment and research of arrhythmic conditions such as long QT syndrome and ventricular tachycardia[2,3,4].
In vitro, Eleclazine hydrochloride (GS 6615 hydrochloride) (1μM) pretreatment of isolated rabbit hearts for 20min significantly accelerated intracellular Ca2+ decay and suppressed the induction of spatially discordant alternans (SDA) under normothermic conditions[5]. Eleclazine hydrochloride (GS 6615 hydrochloride) (10μM) treatment of isolated rabbit atrial myocytes for 5min reduced the late sodium current density induced by isoproterenol (ISO, 15nM) by 41% (p < 0.05)[6].
In vivo, Yorkshire pigs pretreated with Eleclazine hydrochloride (GS 6615 hydrochloride) (0.9mg/kg; intravenous infusion over 15min) showed an 83% reduction in the incidence of 1-2 beat atrial premature beats (APBs) and a 75% reduction in ≥3 APBs induced by epinephrine (2.0μg/kg, intravenous bolus over 1min) at 120min after Eleclazine hydrochloride (GS 6615 hydrochloride) administration[7].

| Cell experiment [1]: | |
Cell lines | Atrial myocytes |
Preparation Method | Atrial myocytes isolated from rabbit hearts were treated with 15nM ISO in the absence or presence of 10μM Eleclazine hydrochloride (GS 6615 hydrochloride) for 5min, and late sodium current (late INa) was recorded using the whole-cell patch-clamp technique. |
Reaction Conditions | 10μM; 5min |
Applications | Treatment with Eleclazine hydrochloride (GS 6615 hydrochloride) reduced ISO-induced late sodium current density by 41% (p < 0.05). |
| Animal experiment [2]: | |
Animal models | Yorkshire pigs |
Preparation Method | Yorkshire pigs were treated with 0.9mg/kg Eleclazine hydrochloride (GS 6615 hydrochloride) (intravenous infusion over 15min), and the incidence of epinephrine-induced APBs was analyzed at multiple time points thereafter (60, 90, 120, 150min). |
Dosage form | 0.9mg/kg; 120min; i.v. |
Applications | Treatment with Eleclazine hydrochloride (GS 6615 hydrochloride) reduced the incidence of 1-2 APBs induced by epinephrine by 83% and the incidence of ≥3 APBs by 75%. |
