  New Azolidinediones as Inhibitors of Protein Tyrosine Phosphatase 1B with Antihyperglycemic Properties

  摘要：

  Insulin resistance in the liver and peripheral tissues together with a pancreatic cell defect are the common causes of type 2 diabetes. It is now appreciated that insulin resistance can result from a defect in the insulin receptor signaling system, at a site post binding of insulin to its receptor. Protein tyrosine phosphatases (PTPases) have been shown to be negative regulators of the insulin receptor. Inhibiton of PTPase may be an effective method in the treatment of type 2 diabetes. A series of azolidinediones has been prepared as protein tyrosine phosphatase 1B (PTP1B) inhibitors. Several compounds were potent inhibitors against the recombinant rat and human PTP1B enzymes with submicromolar IC50 values. Elongated spacers between the azolidinedione moiety and the central aromatic portion of the molecule as well as hydrophobic groups at the vicinity of this aromatic region were very important to the inhibitory activity. Oxadiazolidinediones 87 and 88 and the corresponding acetic acid analogues 119 and 120 were the best h-PTP1B inhibitors with IC50 values in the range of 0.12-0.3 mu M. Several compounds normalized plasma glucose and insulin levels in the ob/ob and db/db diabetic mouse models.

  偶氮苯氧基羟基脲作为5-脂氧合酶的选择性和口服活性抑制剂。

  摘要：

  唑类苯氧基羟基脲是一类新的5-脂氧合酶（5-LO）抑制剂。结构-活性关系研究表明，恶唑尾巴的2-苯基部分的负电取代基增加了这些抑制剂的离体效能。噻唑类似物上的类似取代对离体活性仅有很小的贡献。三氟甲基取代的恶唑24是离体（6 h预处理大鼠）和体内（3 h预处理大鼠）RPAR测定中最佳恶唑系列化合物，ED50值分别约为1和3.6 mg / kg，但在过敏性豚鼠试验中的活性较弱。恶唑50在RPAR和豚鼠体内模型中均具有同等活性，与齐留通相似。未取代的噻唑52是噻唑系列中最好的化合物，在口服剂量为10 mg / kg的情况下，通过抑制RPAR分析（预处理3小时的大鼠）中白三烯B4的生物合成为99％，而在静脉注射剂量为10 mg / kg的情况下，对变应性豚鼠的支气管收缩作用抑制了50％公斤。在体外测定中，恶唑24表现出高选择性的5-LO抑制活性，IC50值范围从小鼠巨噬细胞中的0.08 microM到人外周单核细胞中的0

  A facile highly regioselective process is described for the formation of 4-chloromethyl-1,3-oxazoles from 1,3-oxazole N-oxide/HCl salts. An explanation is presented for the high regioselectivity in deoxygenation-chlorination using POCl3 with HCl salts compared to the corresponding free N-oxides. The method is quite general and the products are isolated by direct precipitation in all cases studied.
