Moreover, IMP-A did not suppress diazoxide-induced preconditioning (EC50 10.66 ОјM) in a rat model of a cardiac ischemia/reperfusion. These results suggest that the cyclohexylureia portion of glibenclamide is indispensable for mitoKATP inhibition. A glibenclamide analog that lacks its cyclohexylurea portion (IMP-A) loses its ability to inhibit diazoxide-induced swelling. We also show how diazoxide and glibenclamide compete for the same binding site in mitoSUR. Here, we show data that reinforce the existence of a mitochondrial sulfonylurea receptor (mitoSUR) as part of the mitoKATP. However, the mechanisms of action of these drugs and how mitoKATP respond to them are poorly understood. mitoKATP opening-induced cardioprotection (using the pharmacological agent diazoxide) is preventable by antagonists, such as glibenclamide. Mitochondrial ATP-sensitive potassium channels (mitoKATP) locate in the inner mitochondrial membrane and possess protective cellular properties. The results suggest that the use of uridine can be a potentially effective approach to the management of cardiovascular diseases.

Intravenously injected uridine was more rapidly eliminated from the blood in hypoxia than in normoxia, and the level of the mitoK ATP channel activator UDP in the myocardium after uridine administration increased. The data indicate that the cardioprotective action of uridine may be related to the activation of the mitoK ATP channel.

The blocker of the mitochondrial ATP-dependent potassium (mitoK ATP ) channel 5-hydroxydecanoate limited the positive effects of uridine. This led to a reduction of the necrosis zone in the myocardium and disturbances in the heart rhythm. In both models, treatment with uridine (30 mg/kg) prevented a decrease in cell energy supply and in the activity of the antioxidant system, as well as an increase in the level of lipid hydroperoxides and diene conjugates. Two rat models were used: (1) acute myocardial ischemia induced by occlusion of the left coronary artery for 60 min and (2) myocardial ischemia/reperfusion with 30-min ischemia and 120-min reperfusion.

A possible mechanism of its cardioprotective action was established.

The effect of uridine on the myocardial ischemic and reperfusion injury was investigated.
