great fungicidal property against B. cinerea (EC50 < 4 μg/mL); especially, a3 presented significantly prominent inhibitory activity with an EC50 of 0.027 μg/mL. In the pursuit of further expanding the antifungal spectrum of cryptolepine, ring-opened compound f1 produced better activity with an EC50 of 3.632 μg/mL against R. solani and an EC50 of 5.599 μg/mL against F. graminearum. Furthermore, a3 was selected
受天然来源的多种衍生物的广泛抗植物病原学应用的启发,随后设计,合成并评价了隐山平及其衍生物对四种农业重要真菌solani Rhizoctonia solani,Botrytis cinerea,Fusarium graminearum和Sclerotiorum sclerotiorum的抗真菌活性。体外测定结果表明,化合物a1-a24对灰葡萄孢具有很好的杀菌作用(EC 50 <4μg/ mL)。特别是a3的EC 50表现出明显的抑制活性0.027μg/ mL。在追求进一步扩大cryptolepine的抗真菌谱,开环化合物F1产生更好的活性与EC 50的3.632微克/毫升抗水稻纹枯病菌和EC 50 5.599微克/毫升的抗禾谷镰孢。此外,选择a3作为研究其对灰葡萄孢菌的初步抗真菌机制的候选者,这表明不仅有效抑制了孢子萌发,严重破坏了菌丝体的正常生理结构,而且明显地积累了有害的活性氧,并且正
