Glibenclamide (Synonyms:格列本脲; Glyburide)
目录号 : KM7757 CAS No. : 10238-21-8 纯度 : 98%

Glibenclamide (Glyburide) 是一种具有口服活性的 ATP 敏感的 K+ 通道 (KATP) 抑制剂,可用于糖尿病和肥胖的研究。Glibenclamide 抑制 P-glycoprotein。Glibenclamide 直接结合并阻断KATP 的 SUR1 亚基并抑制囊性纤维化跨膜传导调节蛋白 (CFTR)。Glibenclamid 通过诱导膜离子通透性干扰线粒体生物能。Glibenclamid 可诱导自噬。

生物活性

Glibenclamide (Glyburide) is an orally active ATP-sensitive K channel (KATP) inhibitor and can be used for the research of diabetes and obesity. Glibenclamide inhibits P-glycoprotein. Glibenclamide directly binds and blocks the SUR1 subunits of KATP and inhibits the cystic fibrosis transmembrane conductance regulator protein (CFTR). Glibenclamide interferes with mitochondrial bioenergetics by inducing changes on membrane ion permeability. Glibenclamide can induce autophagy.

体外研究

Glibenclamide (Brown adipocytes; 10 μΜ; 1 day) has no effect on adipocyte differentiation. Glibenclamide (Ucp1-2A-GFP brown adipocyte) significantly increases UCP1 expression. Glibenclamide directly binds and blocks the SUR1 subunits of ATP-dependent potassium channels (KATP) and consequently increases insulin secretion from the pancreatic β cells. Glibenclamide interferes with mitochondrial bioenergy by permeating mitochondrial intima with Cl and promoting mitochondrial net Cl/K cotransport. Glibenclamide induced autophagy inhibits its insulin secretion-improving function in β cells.

体内研究

Glibenclamide (2 mg/kg; p.o.) increases of insulin release and rapid drop of blood glucose level.
Glibenclamide (50 μg/kg; p.o.) does not cause significant change, such as body weight or body composition.
