Dibutyryl-cGMP sodium (Bt2cGMP sodium) is a cell-permeable cGMP analog. Dibutyryl-cGMP sodium preferentially activates cGMP-dependent protein kinase (PKG). Dibutyryl-cGMP sodium inhibits [3H]-arachidonic acid release in human platelets stimulated by gamma
Gliclazide is a whole-cell beta-cell ATP-sensitive potassium currents blocker with an IC50 of 184 nM. Ethyl tosylcarbamate is an intermediate in the synthesis of Gliclazide (G409877).
U-56324 is a hypoglycemic agent derived from nicotinic acid. It was found to inhibit the activity of ATP-sensitive potassium channels in excised patches from mouse pancreatic B-cells.
Desethylamiodarone hydrochloride (N-desethylamiodarone hydrochloride) is the primary active metabolite of amiodarone, formed by the CYP3A isozyme. Amiodarone is an antiarrhythmic drug that inhibits ATP-sensitive potassium channels with an IC50 of 19.1 μM.
AZ-DF 265 is a hypoglycaemic drug which stimulates insulin release. AZ-DF-265 inhibits ATP-sensitive potassium channels and displaces [3H]-glibenclamide from the sulphonylurea receptor.
Nicorandil-d4 is intended for use as an internal standard for the quantification of nicorandil by GC- or LC-MS. Nicorandil is an activator of sulfonylurea receptor 2B (SUR2B) linked to ATP-sensitive potassium channel Kir6.2 (EC50 = ~10 µM) and a nitric oxide (NO) donor. It is selective for SUR2B/Kir6.2 over the SUR2A/Kir6.2 channel (EC50 = >500 µM). Nicorandil activates soluble guanylate cyclase in a cell-free assay and relaxes partially depolarized isolated bovine coronary artery strips (EC50 = 4.4 µM). It decreases mean blood pressure, coronary resistance, and heart rate, as well as increases coronary sinus outflow, in dogs when administered intravenously at a dose of 1 mg/kg. Nicorandil increases survival and decreases infarct size in a rabbit model of myocardial ischemia-reperfusion injury induced by left coronary artery occlusion. Formulations containing nicorandil have been used in the treatment of angina pectoris.
Tilisolol is a nonselective blocker of beta-adrenergic. Tilisolol hydrochloride dilates coronary arteries through an ATP-sensitive K(+)-channel opening mechanism in dogs.
Nicorandil N-oxide, a metabolite of nicorandil, functions as an activator of the ATP-sensitive potassium channel Kir6.2 (SUR2B/Kir6.2) and is associated with the sulfonylurea receptor 2B (SUR2B), while also serving as a nitric oxide donor.

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).
Isopulegol presents depressant- and anxiolytic-like effects, it also has anticonvulsant and bioprotective effects against PTZ-induced convulsions are possibly related to positive modulation of benzodiazepine-sensitive GABAA receptors and to antioxidant properties.Isopulegol presents significant gastroprotective effects in both ethanol- and indomethacin-induced ulcer models, which appear to be mediated, at least in part, by endogenous prostaglandins, K(ATP) channel opening, and antioxidant properties.
