  • Diabetes is a common endocrine and metabolic disorder with a genetic tendency.
  • the main cause is absolute or relatively insufficient insulin secretion, which causes sugar, fat, protein and secondary vitamin, water, and electrolyte metabolism disorders, manifested as blood glucose, urine Elevated sugar, the patient showed symptoms such as drinking more, eating more, polyuria, dry mouth and general weakness.
  • the population incidence rate is 1% to 5%, which is increasing. It is related to cancer and cardiovascular diseases as the world's three major diseases.
  • the purpose of diabetes treatment is to correct glucose metabolism disorders to eliminate symptoms, promote recovery of islet function, improve insulin resistance, maintain good health and physical strength, and prevent various complications.
  • Diabetes is generally divided into two types: insulin-dependent (type I, IDDM) and non-insulin-dependent (type ⁇ , NIDDM). Because the pathogenesis of the two types of diabetes is different, the medication is also very different, as described below.
  • Type I diabetes is an abnormal response of islet cells caused by a viral infection to people with a genetic predisposition through the immune mechanism, causing the islets to begin to destroy to completely lose function. About 5% of diabetes is type I.
  • the current drugs for the treatment of type I diabetes include exogenous insulin (including human insulin and animal insulin), drugs with insulin-like effects, insulin-like growth factor-1 (IGF-1), new long-acting insulin preparations, and Jinqijiang Sugar flakes and more.
  • a small number of type 2 diabetes is the direct damage of islet ⁇ cells, which reduces insulin secretion. Most of these factors cause the muscle, liver, and adipose tissue in the body to decrease sensitivity to islets and reduce glucose uptake. Most people with diabetes have type II diabetes.
  • the drugs for clinical treatment of NIDDM are mainly sulfonylureas, biguanides, other hypoglycemic agents and auxiliary drugs.
  • the sulfonylurea hypoglycemic drug binds to the receptor of the pancreatic ⁇ cell membrane, it closes the potassium ion channel, blocks the potassium ion outflow, causes the cell membrane to depolarize, promotes the opening of the Ca 2+ channel, and causes extracellular calcium ions to flow in and intracellularly.
  • An increase in calcium ion concentration triggers the release of insulin. It is divided into two generations according to its appearance. The first generation includes tolamide, the second generation includes glibenclamide (hypoglycemic), gliclazide (Dalmecon), and glipizide (Mepilidine ) And Gliquidone (Sugarpine).
  • Biguanide antihyperglycemic drugs suppress appetite, increase the binding of insulin to receptors, promote the anaerobic lysis of brachiose by cells, inhibit tissue respiration, and inhibit glycogenogenesis.
  • hypoglycemic agents are mainly thiazolidinediones (eg, troglitazone, rosiglitazone, Pioglitazone, etc.), ⁇ 3-adrenergic receptor modulators, glucagon receptor antagonists, fatty acid metabolism interference drugs, ⁇ -glucosidase inhibitors (such as acarbose, voglibose, miglitol Etc.), aldose reductase inhibitors, etc.

  • GLP-1 is secreted by intestinal Langham cells, and through highly specific binding to GLP-1 receptor (GLP-1 Receptor, GLP-1R) of islet ⁇ cells, cAMP is synthesized by activating adenylate cyclase, and Further activates protein kinases.
  • Metabolic signals glucose metabolism and kinase signals (GLP-1 binding) act synergistically at the cell membrane level, eventually leading to Ca 2+ channels opening, Ca 2+ influx, and further stimulating insulin secretion while inhibiting glucagon production
  • GLP-1 also has neuroregulatory functions, which can delay gastric emptying and reduce appetite. These are very beneficial for the control of diabetes.
  • GLP-1 stimulates insulin secretion depending on blood glucose concentration. As the blood glucose concentration decreases, GLP-1 promotes insulin secretion reduction. Therefore, the blood glucose lowering effect of GLP-1 is self-limiting, and hypoglycemia does not occur.

糖尿病(DM)是一种常见的有遗传倾向的内分泌代谢病, 主要病因是胰岛素分泌绝对 或相对不足, 引起糖、 脂肪、 蛋白质和继发的维生素、 水、 电解质代谢紊乱、 表现为血糖、 尿糖升高, 病人表现多饮、 多食、 多尿、 口干及全身无力等症状。 人群发病率为 1%~5%, 具有日渐增高的趋势。它与癌症、心血管疾病被称为世界性三大疾病。糖尿病治疗的目的是 纠正糖代谢紊乱, 以消除症状, 促进胰岛功能的恢复, 改善胰岛素抵抗, 维持较好的健康和 体力, 以及防治各种并发症。
糖尿病一般分为胰岛素依赖型(I型, IDDM)和非胰岛素依赖型(Π型, NIDDM)两类, 由于两类糖尿病的发病机制不同, 所以用药亦迥异, 分述如下。
I型糖尿病是病毒感染对有遗传倾向的人通过免疫机制引起胰岛细胞的异常反应, 致 使胰岛开始破坏至完全丧失功能。 约 5%的糖尿病为 I型。 目前治疗 I型糖尿病的药物主要 有外源性胰岛素 (包括人胰岛素和动物胰岛素), 有胰岛素样作用的药物, 胰岛素样生长因 子一 1 (IGF— 1), 新长效胰岛素制剂, 金芪降糖片等。
II型糖尿病少数是胰岛 β细胞直接受损,使胰岛素分泌减少。多数是上述因素造成体内 肌肉、肝、脂肪组织, 对胰岛敏感性降低, 对葡萄糖摄取减少。大多数糖尿病患者为 II型糖 尿病。 目前临床治 NIDDM的药物主要有磺脲类、 双胍类、 其他降糖药及辅助用药等。
磺脲类降糖药物与胰腺 β细胞膜的受体结合后, 关闭钾离子通道, 阻断钾离子外流, 导 致细胞膜去极化, 促使 Ca2+通道开放, 使胞外钙离子内流, 胞内钙离子浓度增加后, 触发胰 岛素的释放。按其问世先后分为两代,第一代包括甲苯磺丙脲,第二代有格列本脲(优降糖)、 格列齐特(达美康), 格列吡嗪(美吡哒)和格列喹酮 (糖适平)等。
双胍类降糖药物抑制食欲, 增加胰岛素与受体的结合, 促进细胞对臂萄糖的无氧酵解, 抑制组织呼吸, 抑制肝糖元异生。 主要有二甲双胍、 苯乙双胍和丁双胍。
其他降糖药主要有噻唑烷二酮类(thiazolidinediones)药物(例如曲格列酮, 罗格列酮, 吡格列酮等), β3-肾上腺素受体调节剂, 胰高血糖素受体拮抗剂, 脂肪酸代谢干扰药, α— 糖苷酶抑制药 (例如阿卡波糖, 伏格列波糖, 米格列醇等), 醛糖还原酶抑制剂等。 最近,对糖代谢相关内源肽激素的研究进展为糖尿病的治疗提供了新的思路。当人体摄 入营养物质时, 肠内分泌细胞释放肠肽激素, 主要为胰高血糖素样肽一 1 ( Glucagon like Peptide- 1, GLP- 1 )和糖依赖的促胰岛素肽(Glucose- dependant Insulinotropic Peptide, GIP) , 并通过其对胰岛素生成、 胃肠道蠕动、 胰岛细胞增殖等的作用调节代谢。 其中 GLP 一 1由肠朗罕氏细胞分泌, 通过与胰岛 β细胞的 GLP— 1受体(GLP—l Receptor, GLP-1R) 高度特异性结合, 激活腺苷酸环化酶而合成 cAMP,并进一步激活蛋白激酶。 代谢信号(糖代 谢)和激酶信号 (GLP- 1结合)在细胞膜水平协同作用, 最终导致 Ca2+通道开放, Ca2+内流, 并进一步剌激胰岛素分泌, 同时抑制胰高血糖素的产生, 使餐后血糖降低以维持恒定水平。 GLP—1还具有神经调节功能, 可延迟胃排空, 减少食欲。 这些都对糖尿病的控制非常有利。 正常情况下, GLP— 1刺激胰岛素分泌是依赖血糖浓度的, 随着血糖浓度降低, GLP— 1促胰 岛素分泌作用降低, 因此, GLP- 1 的降血糖作用是自限的, 不会发生低血糖, 因而, 从糖 尿病治疗的角度看, 类似于 GLP-1作用的药物是非常理想的治疗糖尿病药物。 寻找 GLP— 1R 的激动剂已成为国际新药开发机构的研究热点。 目前, 针对 GLP- 1R的药物研究主要集中在 多肽调节剂, 例如 Amylin公司的 AC2993已在美国申请临床(IND) , 它是 39-氨基酸多肽, 具有 GLP-1的促胰岛素分泌作用。 由于多肽药物不便口服, 易于降解, 寻找非肽类 GLP-1R 调节剂是目前研究的新方向。

2、 细内 cAMP浓度测定 因上述检测通过报告基因的表达情况间接判断细胞内的 cAMP浓度水平,是一种间接检 测方法。为确定活性化合物确实可使细胞内 cAMP浓度升高,直接以 cAMP检测试剂盒进行功 能性复筛。
2. 1、 试验材料与仪器
cAMP检测试剂盒(Applied Biosystems公司)
Forma二氧化碳培养箱(Forma公司)
Victor 2读板机(Wallac公司)。
GLP— 1R和荧光素酶稳定表达的 HEK 293细胞株(国家新药筛选中心)
测定化合物: 2f
cAMP标准品 (试剂盒自带, Applied Biosystems公司)
2. 2试验方法
HEK 293细胞以 20000个 /lOOul/孔接入%孔培养板, 37Ό培养过夜,用二甲亚砜将 2f稀释至 1,00E-03M、 1.00E-04M、 1.00E-05M、 1.00E-06M、 1.00E-07M, 然后以 lul/ 孔加入上述 96孔微量培养板中。 37°C、 5%C02条件下培养 lh。按 cAMP-Screen DirectTM System试剂盒说明检测细胞内 cAMP浓度水平。
2. !H式验结果
细胞内 cAMP浓度测定结果见图 2。 图 2所示的结果表明, 随着 2f浓度的增加, 所刺 激产生的 cAMP浓度呈指数上升, 提示其作为 GLP— 1R激动剂, 对 GLP—1R的信号传导 起了一定作用。 当 2f浓度升至 30uM和 lOOuM时, cAMP浓度呈下降趋势, 是由高浓度 2f 的细胞毒效应所致。
3、 配体结合活力测试
为确定活性化合物对受体的结合能力, 制备大量表达 GLP— 1R的细胞, 以 1251标记的 GLP— 1作为配基, 同时加入待检测化合物。 当待测化合物与 1251标 GLP— 1进行竞争性结 合时,细胞膜上的同位素标记减少。据此可评估化合物对受体的的亲和力(J Md Endocrinol. 2000 Vol.25:321-35; J Biomol Screen. 2000 Vol.5:377-84)。
3. 1试验材料与仪器-
HEK293/GLP1R+Luc细胞株(国家新药筛选中心)
标记化合物: 1251标记的 GLP-1 ( Amersham Biosciences公司)
Wallac MicroBata工作站 (Perkin Elmer公司)。

洗涤溶液:
20 mM tris-HCl (pH 7.4), 100 mM NaCI, 15 mM NaF
闪烁液(Wallac公司)
待测化合物以二甲亚砜稀释, 浓度梯度为: O.lnM, InM, ΙΟηΜ, ΙΟΟηΜ, ΙΟΟΟηΜ, ΙΟΟΟΟηΜ, lOOOOOnMc
3. 2试验方法
取 105对数生长期的 HEK 293/GLP1R+Luc细胞,于 25°C条件下, 200μ1测试缓冲 液中, 与1251标 GLP-1阳性肽 (终浓度 40ρΜ)共孵育 4小时, 同时加入非标记阳性肽 或待筛选药物。使用细胞收集器,用洗涤溶液洗涤细胞三次。加入闪烁液,在 Microbata 计数器上读出每孔读数。
3. 3试验结果
受体结合试验结果见表 3, 表 3所示的结果表明, 2f对GLP— 1R具有较好的亲和活性, wang520、 wang516作用稍弱, 而其他化合物在测试的浓度范围内基本上没有结合。
