To find new higher fungicidal activities lead compounds and develop new eco-friendly agrochemicals, natural product phenazine-1-carboxylic acid (PCA) as scaffold, a series of 1,3,4-oxadiazol-2-yl thioether derivatives was synthesized and bio-assayed. The results reveal that most target compounds possessed moderate to good fungicidal activities against R. solani, S. sclerotioru and P. oryzac Cavgra
为了寻找新的更高的杀菌活性先导化合物并开发新的环保农用化学品,以天然产物吩嗪-1-羧酸(PCA)为支架,合成了一系列1,3,4-恶二唑-2-基硫醚衍生物并对其进行生物降解。分析。结果表明,大部分目标化合物具有适度的对抗良好的杀菌活性纹枯病,S. sclerotioru和P. oryzac Cavgra。化合物6N和6O针对表现出超过90%的生物活性S. sclerotioru。化合物6n和6o的EC 50值分别为11.16和30.47μM,特别是化合物6n对Sclerotioruru的抑制作用与PCA(10.49μM)相同 该结果为进一步研究提供了有价值的先导化合物。
