To discover the pronounced acaricide candidate, herein, a series of 3-formyl-N-(un)substituted benzylindole pyrimidines were prepared by structural modification of indoles at the N-1 and C-3 positions via the successive Vilsmeier–Haack–Arnold (VHA), aldol condensation, and cyclization reactions. The steric structures of nine compounds were undoubtedly confirmed by X-ray single-crystallography. Against
为了发现明显的杀螨剂候选物,本文通过连续的 Vilsmeier-Haack-Arnold ( VHA)、羟醛缩合和环化反应。9种化合物的空间结构无疑已通过X射线单晶分析得到证实。针对朱砂叶螨,化合物V-15、V-31、V-34、V-42、V-44和V-60表现出良好的杀螨活性,LC 50值为 0.299 – 0.481 mg/mL。特别是,化合物V-34的杀螨活性是其前体6-甲基吲哚的4.2倍。扫描电子显微镜(SEM)成像显示,经V-34处理的朱砂毛鳞片的角质层结构被严重破坏。此外,RNA-Seq分析表明,化合物V-34可以通过花生四烯酸和亚油酸代谢以及溶酶体途径调节朱砂的稳态代谢。这些结果表明化合物V-34可以作为先导杀螨剂进行进一步研究。
