Eighteen hexahydropyrrolo[2,3-b]indole derivatives were synthesized and evaluated their in vitro antifungal activities against five phytopathogenic fungal strains through the mycelium growth rate method. Analysis of the structure-activity relationship on these synthesized compounds revealed that the introduction of benzyl or substituted benzyl group at the C-3a or N-8 position of the pyrroloindoline
合成了十八种六氢吡咯并[2,3-b]吲哚衍生物,并通过菌丝生长法评估了其对五种植物病原真菌的体外抑菌活性。对这些合成化合物的结构活性关系的分析表明,在吡咯并吲哚啉支架的C-3a或N-8位置引入苄基或取代的苄基,对所有测试的植物病原真菌具有比化合物4a更高的抗真菌活性(均为C -3a和N-8位是异戊二烯基)。尤其是,化合物4r在所有测试化合物中均表现出最有效的抗青霉镰刀菌和禾谷镰刀菌的抗真菌活性,IC50值分别为4.61和5.02μg/ mL。此外,
