Abstract

The cardioprotective effects of necroptosis inhibitors necrostatin-1 and necrostatin-5 were studied on the isolated heart model in rats. Intraperitoneal injection of necrostatin-1 (1.65 mg/kg) or necrostatin-5 (2.46 mg/kg) 60 min before reperfusion of the isolated heart reduced the infarction zone caused by 30-min global ischemia and 120-min reperfusion. Intracoronary injection of necrostatin-1 (44.5 μmol/liter) caused an increase of left-ventricular systolic pressure, that is produced a positive inotropic effect, but did not reduce the infarction zone.
