Anti-Ischemic Activity of Triamine ALM-802 under Conditions of Endothelial Dysfunction

  • Published:
Bulletin of Experimental Biology and Medicine Aims and scope

Anti-ischemic activity of N1-(2,3,4-trimethoxybenzyl)-N2-{2-[(2,3,4-trimethoxybenzyl)amino] ethyl}-1,2-ethanediamine (ALM-802) based on the structure of standard p-FOX inhibitors trimetazidine and ranolazine was studied on the model of endocardial ischemia in intact rats and animals with endothelial dysfunction. Acute endocardial myocardial ischemia was caused by infusion of isoproterenol (20 μg/kg/min intravenously). Endothelial dysfunction in rats was modeled by inducing hyperhomocysteinemia (3 g/kg methionine intragastrically one a day over 7 days). The reference drugs trimetazidine (30 mg/kg, intravenously) and ranolazine 10 mg/kg, intravenously) that were effective only in intact rats. In contrast, ALM-802 (2 mg/kg, intravenously) showed a pronounced anti-ischemic effect in animals with endothelial dysfunction, which suggests that the mechanisms of its cardioprotective action differ from those known for p-FOX inhibitors.
