  Antihyperglycemic activity of new 1,2,4-oxadiazolidine-3,5-diones

  摘要：

  A series of 1,2,4-oxadiazolidine-3,5-diones was synthesized and evaluated as oral antihyperglycemic agents in the obese insulin resistant db/db and ob/ob mouse - the two models for Type 2 diabetes mellitus. The majority of the prepared methoxy- and ethoxy-linked oxazole 1,2,4-oxadiazolidine-3,5-diones normalized plasma glucose levels at the 100 mg kg(-1) oral dose in the db/db diabetic mouse model, and several amongst them reduced the glucose levels at the 20 mg kg(-1) oral dose. The most potent compounds in the db/db mouse model were also active in the ob/ob mouse model normalizing the plasma glucose levels at the 20 mg kg(-1) oral dose. The trifluoromethoxy analog 32 was the most active compound of the series, reducing significantly the plasma glucose levels at the 5 mg kg(-1) oral dose. Oxadiazole-tailed 1,2,4-oxadiazolidine-3,5-diones were also active in both the db/db and ob/ob diabetic mouse models normalizing plasma glucose levels at the 100 mg kg(-1) oral dose.

  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
