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。

We recently reported on the development of a novel series of BRAF inhibitors based on a tripartite A-B-C system characterized by a para-substituted central aromatic core connected to an imidazo-[4,5]pyridin-2-one scaffold and it substituted urea linker. Here, we present it new series of BRAY inhibitors in which the central phenyl ring connects to the hinge binder and substrate pocket of BRAF with a meta-substitution pattern. The optimization of this new scaffold led to the development of low-nanomolar inhibitors that permits the use of a wider range of linkers and terminal C rings while enhancing the selectivity for the BRAF enzyme in comparison to the para series.
