  新型的非噻唑烷二酮类，非羧酸类高选择性过氧化物酶体增殖物激活受体（PPAR）γ激动剂：苄基吡唑酰基磺酰胺的设计与合成

  摘要：

  在这里，我们描述了作为非噻唑烷二酮（TZD），非羧酸基过氧化物酶体增殖物激活受体（PPAR）γ激动剂的新型苄基吡唑酰基磺酰胺的设计，合成和结构-活性关系。内部弱激动剂2与已报道的PPARγ配体结合域结合的对接模型分析表明，对2的羧酸进行修饰将有助于加强2与TZD口袋的相互作用，并提供非基于羧酸的激动剂。在这项研究中，我们使用酰基磺酰胺基团作为TZD的开环类似物，取代了2的羧酸部分; 此外，对磺酰基上的末端烷基链进行初步修饰，得到铅化合物3c。随后优化所得化合物，得到具有高代谢稳定性和显着抗糖尿病活性的有效激动剂25c，30b和30c。此外，我们已经描述了基于羧酸的激动剂1和酰磺酰胺3d在结合方式上的差异。
