K+ channel openers activate brain sulfonylurea-sensitive K+ channels and block neurosecretion.
Vascular K+ channel openers such as cromakalim, nicorandil, and pinacidil potently stimulate 86Rb+ efflux from slices of substantia nigra. This 86Rb+ efflux is blocked by antidiabetic sulfonylureas, which are known to be potent and specific blockers of ATP-regulated K+ channels in pancreatic beta cells, cardiac cells, and smooth muscle cells. K0.5, the half-maximal effect of the enantiomer (-)-...
متن کاملEffect of ATP-Dependent K+ Channel Openers and Blockers on Serum Concentration of Aldosterone in Rats
There are many reports for involvement of ATP-sensitive potassium channels in pancreatic, cardiac and vascular smooth muscle cells. This study examined the effect of single doses of K+ channel openers diazoxide, minoxidil and K+ channel blockers chlorpropamide, glibenclamide on serum concentration of aldosterone in male rats. Blood samples were obtained 60 minutes after drug treatment and serum...
متن کاملATP-sensitive potassium (K(ATP)) channel openers diazoxide and nicorandil lower intraocular pressure in vivo.
PURPOSE To evaluate the expression of ATP-sensitive potassium (K(ATP)) channel subunits and study the effect of K(ATP) channel openers diazoxide and nicorandil on intraocular pressure (IOP) in an in vivo mouse model. METHODS Expression of K(ATP) channel subunits in normal C57BL/6 mouse eyes was studied by immunohistochemistry and confocal microscopy. Wild-type C57BL/6 mice were treated with K...
متن کاملSulfonylurea receptor-dependent and -independent pathways mediate vasodilation induced by ATP-sensitive K+ channel openers.
ATP-sensitive K+ (KATP) channel openers are vasodilators that activate both plasma membrane and mitochondrial KATP channels. Here, we investigated the molecular mechanisms by which diazoxide and pinacidil induce vasodilation by studying diameter regulation of wild-type [SUR2(+/+)] and sulfonylurea receptor (SUR) 2-deficient [SUR2(-/-)] mouse myogenic mesenteric arteries. Ryanodine (10 microM), ...
