Anti-nociceptive effect of cimetidine in mice: the role of ATP-sensitive potassium channels
Recent studies have shown that intracerebroventricular administration of cimetidine (CIM) induces anti-nociceptive and anti–inflammatory effects in rats. However, the underlying mechanism of CIM effect has not been determined yet. This study was planned to determine the anti-nociceptive effect of CIM (50 mg/kg, i.p.) in male mice (25-30 g, n = 80) using tail flick test. Also, the role of ATP-se...

متن کاملCardiovascular ATP-sensitive potassium channels
Sulfonylurea drugs stimulate endogenous insulin secretion by blockade of ATP-sensitive potassium channels in pancreatic beta cells. These drugs are widely used in the treatment of type 2 diabetes. However, as ATP-sensitive potassium channels also exist in cardiomyocytes and coronary and peripheral arterial vascular smooth muscle cells, sulfonylurea drug usage in theory may cause unwanted cardio...
متن کاملMCC-134, a single pharmacophore, opens surface ATP-sensitive potassium channels, blocks mitochondrial ATP-sensitive potassium channels, and suppresses preconditioning.
BACKGROUND MCC-134 (1-[4-(H-imidazol-1-yl)benzoyl]-N-methylcyclobutane-carbothioamide), a newly developed analog of aprikalim, opens surface smooth muscle-type ATP-sensitive potassium (K(ATP)) channels but inhibits pancreatic K(ATP) channels. However, the effects of MCC-134 on cardiac surface K(ATP) channels and mitochondrial K(ATP) (mitoK(ATP)) channels are unknown. A mixed agonist/blocker wit...
متن کاملEndothelial biology and ATP-sensitive potassium channels
ATP sensitive potassium (KATP) channels are metabolic sensors with channel activity promoted by decreases in ATP andnor increases in MgADP. The most studied are channels present in cardiac myocytes and pancreatic b cells but KATP currents also exist more widely in a range of tissues and organs [1,2]. The channel is a hetero-octamer comprising four sulphonylurea receptors and four pore-forming i...
