privileged scaffolds, thiohydantoin and spirocyclic butenolide, which are widely found in natural products. The synthesized compounds were characterized by 1H NMR, 13C NMR, and high-resolution electrospray ionisation mass spectrometry. The in vitro antioomycete activity evaluation showed that most of the compounds exhibited excellent inhibitory activities against different developmental stages in the life
新型杀真菌剂的设计基于两种特殊支架的组合,硫代乙内酰脲和螺环丁烯内酯,它们广泛存在于天然产物中。合成的化合物通过1 H NMR、13 C NMR 和高分辨率电喷雾电离质谱法进行表征。体外抗卵菌活性评价表明,大部分化合物对病原性卵菌辣椒疫霉生命周期的不同发育阶段均表现出良好的抑制活性。化合物5j可显着抑制菌丝体生长、孢子囊产生、游动孢子释放和孢囊萌发,EC 50值分别为 0.38、0.25、0.11 和 0.026 μg/mL。体内抗真菌/抗卵菌生物测定结果表明,该系列化合物对致病卵菌立方霜霉菌总体表现出优异的防治效果,其中化合物5j、5l、7j、7k和7l对供试植物病原体具有广谱抗真菌活性。代表性化合物5j对P. capsici的体内保护和治疗效果均优于嘧菌酯。更突出的是,5j显着促进根系生物量积累,并通过胼胝质沉积加固细胞壁。免疫反应相关基因的显着上调表明活性卵菌抑制剂5j也可作为植物诱
