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-sensitivepotassium channels with an IC50 of 19.1 μM.
Gliclazide is a whole-cell beta-cell ATP-sensitivepotassium currents blocker with an IC50 of 184 nM. Ethyl tosylcarbamate is an intermediate in the synthesis of Gliclazide (G409877).
Guanosine 5’-diphosphate (GDP) is a purine nucleotide and biosynthetic precursor of guanosine 5’-triphosphate .1It has been used to study the conformations of GTPases.2GDP (100 μM) activates sulfonylurea receptor 2B (SUR2B) linked to the inward-rectifier potassium channel 6.1 (Kir6.1) in HEK293T cells in a patch-clamp assay.3 1.Berg, J.M., Tymoczko, J.L., and Stryer, L.Biochemistry(2002) 2.Vetter, I.R., and Wittinghofer, A.The guanine nucleotide-binding switch in three dimensionsScience294(5545)1299-1304(2001) 3.Yamada, M., Isomoto, S., Matsumoto, S., et al.Sulphonylurea receptor 2B and Kir6.1 form a sulphonylurea-sensitive but ATP-insensitive K+ channelJ.

AZ-DF 265 is a hypoglycaemic drug which stimulates insulin release. AZ-DF-265 inhibits ATP-sensitivepotassium channels and displaces [3H]-glibenclamide from the sulphonylurea receptor.
