  tyrosine phosphatases (PTPases) have been shown to be negative regulators of the insulin receptor. Inhibition of PTPases may be an effective method in the treatment of Type 2 diabetes. We have identified two novel series of benzofuran/benzothiophene biphenyl oxo-acetic acids and sulfonyl-salicylic acids as potent inhibitors of PTP1B with good oral antihyperglycemic activity. To assist in the design of these

  肝和外周组织中的胰岛素抵抗以及胰腺细胞缺陷是2型糖尿病的常见病因。现在已经认识到，胰岛素抵抗可以由胰岛素受体信号系统中在胰岛素与其受体结合后的位点的缺陷引起。蛋白酪氨酸磷酸酶（PTPases）已被证明是胰岛素受体的负调节剂。抑制PTPases可能是治疗2型糖尿病的有效方法。我们已经确定了两个新颖的苯并呋喃/苯并噻吩联苯氧代乙酸和磺酰水杨酸系列作为具有良好口服降血糖活性的有效PTP1B抑制剂。为了帮助设计这些抑制剂，晶体学研究试图鉴定酶抑制剂的相互作用。晶体配合物的拆分表明抑制剂与酶的活性位点结合，并通过在两个疏水口袋中形成的氢键和范德华相互作用而保持在适当的位置。在含氧乙酸系列中，苯并呋喃/苯并噻吩联苯骨架第2位的疏水取代基与催化位点的Phe182相互作用，对分子的内在活性至关重要。催化位点口袋的疏水区被氧代乙酸部分的α-碳或邻位芳族位置的疏水取代基所利用和利用。水杨酸型抑制剂上类似的邻位

  In this paper, we report the use of potassium organotrifluoroborate salts as nucleophilic organoboron reagents in the Suzuki cross-coupling reactions of 2-halo deazapurines. Regio-isomeric C-2-substituted imidazo[4,5-b]pyridine analogues were synthesized by employing this protocol in good to excellent yields. Whereas aryl and heteroaryl trifluoroborates reacted readily to give the coupled products

  在本文中，我们报告了在三卤代脱氮嘌呤的Suzuki交叉偶联反应中有机三氟硼酸钾盐作为亲核有机硼试剂的用途。通过使用该方案以良好至优异的产率合成了区域异构的C-2-取代的咪唑并[4，5- b ]吡啶类似物。芳基和杂芳基三氟硼酸酯容易反应，以高收率得到偶联产物，而三氟硼酸烷基酯则反应性较低。发现乙酸四丁铵的利用在提高交叉偶联过程的反应速率中起重要作用。另外，在硼酸和有机三氟硼酸钾盐之间进行了比较研究。
