Eleclazine hydrochloride (GS 6615 hydrochloride) (Synonyms: GS 6615 hydrochloride)

Eleclazine hydrochloride is a novel late Na+ current inhibitor with IC50 value of 0.7 uM. target: Na+ current.IC50: 0.7 uM.In vitro: Eleclazine hydrochloride inhibits ATX-II enhanced late INa in ventricular myocytes, shorten the ATX-II induced prolongation of APD, MAPD, QT interval, and decreased spatiotemporal dispersion of repolarization and ventricular arrhythmias. Inhibition by GS-6615 of ATX-II enhanced late INa is strongly correlated with shortening of myocyte APD and isolated heart MAPD[1]. Selective inhibition of cardiac late INa with eleclazine hydrochloride confers dual protection against vulnerability to ischemia-induced AF and reduces atrial and ventricular repolarization abnormalities before and during adrenergic stimulation without negative inotropic effects.
