(USP) heterodimeric receptor, a series of new pyrazole amide derivatives were designed and synthesized. Their structures were confirmed by IR, 1 H NMR, 13 C NMR and elemental analysis. Results from a preliminary bioassay revealed that two of the pyrazole derivatives exhibited promising insecticidal activity. Specifically, compounds 6e and 6i exhibited good activity against Helicoverpa armigera (cotton bollworm)
摘要基于VS008(N-(4-甲基苯基)-3-(叔丁基)-1-(苯基甲基)-1 H-吡唑-5-甲酰胺)和BYIO6830(N'-(3 (5-二甲基苯甲酰基)-N'-叔丁基-5-甲基-2,3-二氢-1,4-苯并二恶英-6-碳酰肼)与蜕皮激素受体(EcR)-的EcR亚基的活性位点结合设计并合成了一系列新的吡咯酰胺衍生物。通过IR,1 H NMR,13 C NMR和元素分析确认了它们的结构。初步生物测定的结果表明,两种吡唑衍生物表现出有希望的杀虫活性。具体而言,化合物6e和6i在低浓度下对棉铃虫(棉铃虫)表现出良好的活性。tebufenozide处理的H表现出的症状。棉铃虫与其经处理的对应物相同。6i表现出与tebufenozide相同的中毒症状。此外,分子对接结果表明,异二聚体受体EcR亚基活性位点的6e和6i结合模式与结合的tebufenozide相似。
