Verwenden
Glyburide (Glibenclamide) is a sulfonylurea compound that modulates insulin production. Sulfonylureas bind to ATP-dependent K+ channels in beta cells of the pancreas, depolarizing them and stimulating the release of Ca2+, which in turn stimulates insulin production. Glyburide (Glibenclamide) is an ATP-dependent K+ channel (KIR6, KATP) and CFTR Cl- channel blocker. This compound inhibits recombinant CFTR Cl- channels (IC50 = 20 ?M).
Definition
ChEBI: An N-sulfonylurea that is acetohexamide in which the acetyl group is replaced by a 2-(5-chloro-2-methoxybenzamido)ethyl group.
Allgemeine Beschreibung
Glyburide (glibenclamide) is 5-chloro-N-[2-[4-[[[(cyclohexylamino)carbonyl]amino]sulfonyl]phenyl]ethyl]-2-methoxybenzamide; this compound can also be named asthe urea—see preceding discussion (Diabeta, Glynase,generic). Some tablet formulations contain micronized drug(formerly Micronase, now only generic). Combinations areavailable with metformin in the United States (Glucovance,generic; tablets, mg glipizide/mg metformin as hydrochloride:1.25/250, 2.5/500, 5/500).
Biologische Aktivit?t
ATP-dependent K + channel (K ATP ) and CFTR Cl - channel blocker. Inhibits K ATP currents in the pancreas, causing an increase in intracellular Ca 2+ and insulin secretion. Inhibits recombinant CFTR Cl- channels with an IC 50 of 20 μ M.
Mechanism of action
This drug belongs to the second-generation sulfonylurea derivatives. Like all of the other
oral hypoglycemic drugs examined, it is a β-cell stimulant in pancreas; but on the other
hand, it increases the sensitivity to insulin, the degree to which it binds with target cells.
At the same time, it differs in that it is easier to tolerate. The hypoglycemic effect sets in at significantly lower doses than with first-generation drugs.
