グリブライド
概要
説明
科学的研究の応用
作用機序
グリブライドは、膵臓のβ細胞のATP感受性カリウムチャネルに結合して阻害することで、血糖降下作用を発揮します。この阻害により、これらのチャネルが閉鎖され、細胞膜の脱分極とそれに続く電位依存性カルシウムチャネルの開口につながります。 カルシウムイオンの流入により、β細胞からインスリンが放出され、血糖値が低下します .

生化学分析
Biochemical Properties
By inhibiting these channels, Glyburide causes an increase in intracellular potassium and calcium ion concentrations . This biochemical interaction triggers the release of insulin, thereby playing a crucial role in the regulation of blood glucose levels .
Cellular Effects
Glyburide exerts significant effects on various types of cells, most notably the beta cells in the pancreas. It stimulates insulin secretion through the closure of ATP-sensitive potassium channels on these beta cells . This action raises intracellular potassium and calcium ion concentrations, which in turn triggers the release of insulin . The increased insulin helps to lower blood glucose levels, thereby managing the symptoms of type 2 diabetes .
Molecular Mechanism
The molecular mechanism of Glyburide involves its binding to and inhibition of the ATP-sensitive potassium channels (K ATP) inhibitory regulatory subunit sulfonylurea receptor 1 (SUR1) in pancreatic beta cells . This inhibition causes cell membrane depolarization, opening voltage-dependent calcium channels . The influx of calcium ions triggers the release of insulin, which then acts to lower blood glucose levels .
Temporal Effects in Laboratory Settings
In laboratory settings, Glyburide has been observed to have a long duration of action as it is given once daily . Its effects on cellular function, such as the stimulation of insulin secretion, are therefore sustained over a long period
Dosage Effects in Animal Models
While specific studies on the dosage effects of Glyburide in animal models are limited, it is known that the drug’s effects can vary with different dosages. For instance, in a study on the brain and whole-body distribution of Glyburide, it was found that the drug’s distribution, metabolism, and elimination are greatly dependent on organic anion transporting polypeptide (OATP) activity .
Metabolic Pathways
Glyburide is metabolized mainly by CYP3A4, followed by CYP2C9, CYP2C19, CYP3A7, and CYP3A5 . These enzymes metabolize Glyburide to various metabolites, including 4-trans-hydroxycyclohexyl glyburide (M1), 4-cis-hydroxycyclohexyl glyburide (M2a), 3-cis-hydroxycyclohexyl glyburide (M2b), 3-trans-hydroxycyclohexyl glyburide (M3), 2-trans-hydroxycyclohexyl glyburide (M4), and ethylhydroxycyclohexyl glyburide (M5) .
Transport and Distribution
Glyburide’s transport and distribution within cells and tissues are greatly influenced by OATP activity . This transporter plays a critical role in the hepatic uptake of Glyburide, which is the first step in its hepatic clearance . Moreover, ATP-binding cassette (ABC) transporters, including P-glycoprotein (P-gp), breast cancer resistance protein (BCRP), and probably multidrug resistance protein 4, work in synergy to limit Glyburide’s brain uptake .
Subcellular Localization
The subcellular localization of Glyburide is primarily within the cytoplasm of cells . It is transported into the cell via OATP and is then distributed within the cell to exert its effects
準備方法
Synthetic Routes and Reaction Conditions: Glyburide is synthesized through a multi-step process involving the reaction of 5-chloro-2-methoxybenzoic acid with 2-aminoethylsulfonamide to form 5-chloro-2-methoxy-N-(2-(4-sulfamoylphenyl)ethyl)benzamide. This intermediate is then reacted with cyclohexyl isocyanate to yield glyburide .

類似化合物との比較
Uniqueness of Glyburide: Glyburide is unique among sulfonylureas due to its balanced pharmacokinetic profile, which provides a prolonged duration of action while maintaining a relatively low risk of hypoglycemia. Its dual excretion pathway (urine and feces) also distinguishes it from other sulfonylureas .

Mechanism of Action |
Glyburide belongs to a class of drugs known as sulfonylureas. These drugs act by closing ATP-sensitive potassium channels on pancreatic beta cells. The ATP-sensitive potassium channels on beta cells are known as sulfonylurea receptor 1 (SUR1). Under low glucose concentrations, SUR1 remains open, allowing for potassium ion efflux to create a -70mV membrane potential. Normally SUR1 closes in response to high glucose concentrations, the membrane potential of the cells becomes less negative, the cell depolarizes, voltage gated calcium channels open, calcium ions enter the cell, and the increased intracellular calcium concentration stimulates the release of insulin containing granules. Glyburide bypasses this process by forcing SUR1 closed and stimulating increased insulin secretion. |
