Abstract

The experiments with the isolated rat heart demonstrated a significant decrease in reperfusion-induced damage of cardiomyocytes upon adding the selective δ1 receptor agonist DPDPE (0.1 mg/l) to the perfusion solution. On the contrary, no cardioprotective effect was observed for 0.5 mg/l concentration of the peptide or after its intravenous injection. Stimulation of the cardiac δ1 opioid receptors by intravenous injection of 0.5 mg/kg DPDPE or its addition to the perfusion solution decreased myocardial contractility both under conditions of normal oxygenation and during reperfusion. Thus, the cardioprotective and negative inotropic effect of DPDPE is mediated by activation of the cardiac δ1 opioid receptors.
