A series of tetrahydro-ß-carbolines substituted with an alkyl or acyl side chain was synthesized and screened for its antifungal activity against plant pathogenic fungi (Bipolaris oryzae, Curvularia lunata, Fusarium semitectum, and Fusarium fujikuroi). The structure activity relationship revealed that the substituent at the piperidine nitrogen plays an important role for increasing antifungal activities
合成了一系列被烷基或酰基侧链取代的四氢-β-咔啉,并筛选了其对植物病原真菌(米双极、弯孢、半顶镰刀菌和藤黑镰刀菌)的抗真菌活性。构效关系表明,哌啶氮上的取代基对增加抗真菌活性起着重要作用。在该系列中,2-octyl-2,3,4,9-tetrahydro-1H-pyrido[3,4-b]indole (3g) 显示出有效的抗真菌活性,最小抑制浓度为 0.1 μg/mL,包括良好的抑制作用与两性霉素 B 相比,浓度为 100 μg/mL 时对真菌径向生长的活性。
