Cytoprotective action of the potassium channel opener NS1619 under conditions of disrupted calcium homeostasis.
Cytoprotective properties of potassium channel openers (KCOs) have been demonstrated in several models of cell injury, mainly in ischemia-reperfusion-induced damage of cardiac muscle. The mechanism responsible for the observed cytoprotection and the relative contribution of plasma membrane or inner mitochondrial membrane potassium channels regarding the beneficial effects exerted by KCOs remain...
متن کاملA new ATP-sensitive potassium channel opener protects endothelial function in cultured aortic endothelial cells.
OBJECTIVE Endothelial dysfunction is an early risk factor for cardiovascular disease and hypertension. Mechanisms that participate in endothelial dysfunction include reduced nitric oxide (NO) generation and increased endothelin-1 (ET-1) generation. Endothelial ATP-sensitive potassium (K(ATP)) channels are responsible for maintaining the resting potential of endothelial cells and modulating the ...
متن کاملStoichiometry of potassium channel opener action.
Potassium channel openers (KCOs; e.g., P1075, pinacidil) exert their effects on excitable cells by opening ATP-sensitive potassium channels. These channels are heteromultimers composed with a 4:4 stoichiometry of an inwardly rectifying K(+) channel subunit plus a regulatory subunit comprising the receptor sites for hypoglycemic sulfonylureas and KCOs (a sulfonylurea receptor). To elucidate stoi...
متن کاملPotassium Channel Opener May Become Resource for Treating Resistant Epilepsy
In the early 1990s, researchers began looking at potassium channel openers for seizure control. Over the past 10 years, in vitro research and animal studies demonstrated that potassium channel openers could control seizure activity in a dose-dependent way.1-4 Clinical trials are now confirming these findings.5 Among the calcium channel openers that have been studied, the agent retigabine has co...
متن کاملMitochondrial potassium channel opener diazoxide preserves neuronal-vascular function after cerebral ischemia in newborn pigs.
BACKGROUND AND PURPOSE N-Methyl-D-aspartate (NMDA) elicits neuronally mediated cerebral arteriolar vasodilation that is reduced by ischemia/reperfusion (I/R). This sequence has been preserved by pretreatment with the ATP-sensitive potassium (K(ATP)) channel opener aprikalim, although the mechanism was unclear. In the heart, mitochondrial K(ATP) channels (mitoK(ATP)) are involved in the ischemic...
