  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。

  摘要：

  摘要通过简便的方法设计和合成了一系列含有苯基噻唑部分的新型1H-吡唑-5-羧酰胺化合物，并通过1 H NMR，质谱和元素分析对其结构进行了表征。生物测定结果表明，大多数标题化合物显示强大的杀菌活性对小麦白粉病和抗杀虫活性蚜蚜。特别是，化合物9B具有EC 50为3.04毫克值/ L抵抗禾白粉菌，其中的杀真菌活性比商业杀真菌剂和的Thifluzamide的Azoxystrobinare更好; 化合物9l的LC 50蚜虫的3.81 mg / L的值与商业杀虫剂Tolfenpyrad相当。建议将含有苯基噻唑部分的1H-吡唑-5-羧酰胺化合物视为进一步设计农药的前体结构。 图形概要通过简便的方法设计和合成了一系列含有苯基噻唑部分的新型1H-吡唑-5-羧酰胺化合物，并通过1 H NMR，质谱和元素分析对其结构进行了表征。生物测定结果表明，大多数标题化合物显示强大的杀菌活性对小麦白粉病和抗杀虫活性蚜蚜。特别是，化合物9B具有EC
