scaffolds—coumarin, chalcone, flavone, flavonol, isoflavone and isoquinolinone. The structural diversity of this library is assessed computationally using cheminformatic analysis. Phenotypic high‐throughput screening of β‐glucuronidase activity uncovers several hits. Further in vivo screening confirms that these hits can induce resistance in rice to nymphs of the brown planthopper Nilaparvata lugens
天然产物是生物分子的主要来源。3-甲基呋喃支架存在于多种植物次生代谢产物化学引发剂中,赋予宿主植物抵抗害虫的能力。本文报道了一种天然产物样库的面向多样性的合成方法,其中3-甲基呋喃核与六种常见天然产物支架(香豆素,查尔酮,黄酮,黄酮醇,异黄酮和异喹啉酮)成角度连接。该库的结构多样性是使用化学信息学分析通过计算评估的。β-葡萄糖醛酸苷酶活性的表型高通量筛选发现了一些成功案例。进一步的体内筛选证实这些命中可以诱导水稻对褐飞虱Nilaparvata lugens的若虫产生抗性。。这项工作验证了以多样性为导向的合成与高通量筛选β-葡萄糖醛酸苷酶活性的组合作为发现新化学引发剂的策略。
