atp-sensitive potassium (katp) channels

Aprikalim (RP 52891) is an adenosine triphosphate potassium channel (KATP) opener that protects against nerve damage in a rabbit model of spinal cord ischemia.Aprikalim inhibits vasoconstriction and inhibits the elevation of [Ca2+]i during myocardial paralysis, and can be used to study cardiovascular disease.

Amiodarone hydrochloride (Amiodarone HCl) is an antianginal and class III antiarrhythmic drug. It increases the duration of ventricular and atrial muscle action by inhibiting POTASSIUM CHANNELS and VOLTAGE-GATED SODIUM CHANNELS. There is a resulting decrease in heart rate and in vascular resistance.

5-Hydroxydecanoate sodium is a selective ATP-sensitive K+ (KATP) channel blocker with an IC50 of approximately 30 μM and a substrate for mitochondrial outer membrane acyl-CoA synthetase, possessing antioxidant properties.

Hydroxyhexamide ((±)-Hydroxyhexamid) is a pharmacologically active metabolite of Acetohexamide, used as a hypoglycemic agent.

Gliclazide-d4 is intended for use as an internal standard for the quantification of gliclazide by GC- or LC-MS. Gliclazide is a sulfonylurea and an inhibitor of pancreatic β-cell ATP-sensitive potassium (KATP) channels. It is selective for pancreatic β-cell over cardiac and arterial smooth muscle cell KATP channels. Gliclazide (5 μM) increases insulin-induced glucose uptake and glucose transporter 4 (GLUT4) translocation to the plasma membrane in a differentiated 3T3L1 adipocyte model of insulin resistance induced by hydrogen peroxide. Gliclazide (5 and 10 μg ml) reduces LDL oxidation by human aortic smooth muscle cells (HASMCs), decreasing TBARS content and 8-isoprostane levels. It also decreases oxidized LDL-induced HASMC proliferation and monocyte adhesion when used at concentrations ranging from 1 to 10 μg ml. Gliclazide (5 mg kg) reduces serum glucose levels and increases glucose uptake by isolated rat hindquarters in a model of diabetes induced by streptozotocin (STZ).

Levcromakalim (BRL 38227) is an activator of the ATP-sensitive K+ channel.

Glibornuride, a blocker of ATP-sensitive K+ channels (pKi: 5.75), inhibits high-affinity [3H]-glibenclamide binding with potencies corresponding to its K+ channel activity.
