用途: Glipizide(K 4024; CP 2872) is used to treat high blood sugar levels caused by a type of diabetes mellitus called type 2 diabetes.Target: Potassium ChannelGlipizide is an oral rapid- and short-acting anti-diabetic drug from the sulfonylurea class. It is classified as a second generation sulfonylurea, which means that it undergoes enterohepatic circulation. Mechanism of action is produced by blocking potassium channels in the beta cells of the islets of Langerhans. By partially blocking the potassium channels, the cell remains depolarized, increasing the time the cell spends in the calcium release stage, which results in signaling leading to calcium influx. The increase in calcium will initiate more insulin release from each beta cell. Sulfonylureas may also cause the decrease of serum glucagon and potentiate the action of insulin at the extrapancreatic tissues [1, 2]. 作用: 格列吡嗪为第二代磺脲类口服降血糖药。主要是促进胰岛β细胞分泌胰岛素,尤其是促进葡萄糖刺激的胰岛素β细胞分泌;还有增强胰岛素作用,从而有效地降低血糖浓度和糖基化血红蛋白;并可改善高脂血症,降低甘油三酯和胆固醇水平,提高高密度脂蛋白胆固醇在总胆固醇中比率;还可抑制血小板聚集和促进纤维蛋白溶解,因而对血管病变可能有一定的防治作用。①促进胰腺胰岛β细胞分泌胰岛素,先决条件是胰岛β细胞还有一定的合成和分泌胰岛素的功能;②通过增加门静脉胰岛素水平或对肝脏直接作用,抑制肝糖原分解和糖原异生作用,肝生成和输出葡萄糖减少;③也可能增加胰外组织对胰岛素的敏感性和糖的利用(可能主要通过受体后作用),因此,总的作用是药动学吸收快,口服后1~2.5小时血药浓度达峰值,作用持续时间可达24小时,T1/2为2.5~4小时。主要经肝代谢失去活性,第l天97%排出体外,第2天100%排出体外。 物理化学性质: CAS号:29094-61-9 常用中文名:格列吡嗪 常用英文名:Glipizide 分子式:C21H27N5O4S 分子量:445.535 密度:1.4±0.1 g/cm3 沸点:676.0±65.0 °C at 760 mmHg 熔点:208-209°C 闪点:362.6±34.3 °C 储存条件:-20°C Freezer |
