Gliburida
Descripción general
Descripción
Es un agente hipoglucémico oral que ayuda a controlar los niveles de azúcar en la sangre al estimular la liberación de insulina del páncreas . La glibúrida se introdujo por primera vez en la práctica clínica en 1969 y desde entonces se ha convertido en un medicamento ampliamente utilizado para el manejo de la diabetes .
Aplicaciones Científicas De Investigación
La glibúrida tiene una amplia gama de aplicaciones de investigación científica:
Mecanismo De Acción
La glibúrida ejerce sus efectos hipoglucémicos al unirse e inhibir los canales de potasio sensibles al ATP en las células beta pancreáticas. Esta inhibición conduce al cierre de estos canales, lo que resulta en la despolarización de la membrana celular y la posterior apertura de los canales de calcio dependientes de voltaje. La entrada de iones de calcio desencadena la liberación de insulina de las células beta, lo que reduce los niveles de glucosa en sangre .
Compuestos Similares:
Singularidad de la Glibúrida: La glibúrida es única entre las sulfonilureas debido a su perfil farmacocinético equilibrado, que proporciona una duración de acción prolongada al tiempo que mantiene un riesgo relativamente bajo de hipoglucemia. Su vía de excreción dual (orina y heces) también la distingue de otras sulfonilureas .
Análisis Bioquímico
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
Métodos De Preparación
Rutas Sintéticas y Condiciones de Reacción: La glibúrida se sintetiza mediante un proceso de varios pasos que involucra la reacción del ácido 5-cloro-2-metoxibenzoico con 2-aminoetilsulfonamida para formar 5-cloro-2-metoxi-N-(2-(4-sulfamoylfenil)etil)benzamida. Este intermedio luego se hace reaccionar con isocianato de ciclohexilo para producir glibúrida .
Métodos de Producción Industrial: La producción industrial de glibúrida implica la optimización de las condiciones de reacción para garantizar un alto rendimiento y pureza. El proceso generalmente incluye pasos como cristalización, filtración y secado para obtener el producto final en su forma pura .
Análisis De Reacciones Químicas
Tipos de Reacciones: La glibúrida experimenta varias reacciones químicas, incluida la oxidación, reducción y sustitución.
Reactivos y Condiciones Comunes:
Oxidación: La glibúrida se puede oxidar utilizando reactivos como peróxido de hidrógeno o permanganato de potasio en condiciones ácidas.
Reducción: La reducción de la glibúrida se puede lograr utilizando agentes reductores como borohidruro de sodio o hidruro de litio y aluminio.
Sustitución: Las reacciones de sustitución que involucran glibúrida a menudo utilizan reactivos como halógenos o agentes alquilantes.
Principales Productos Formados: Los principales productos formados a partir de estas reacciones dependen de los reactivos y condiciones específicos utilizados. Por ejemplo, la oxidación puede producir derivados hidroxilados, mientras que la reducción puede producir productos desclorados o desmetilados .
Comparación Con Compuestos Similares
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. |
