and some of their dehydration derivatives were designed, synthesized and evaluated for their antifungal activities. Some compounds exhibited moderate inhibitory activities against seven plant pathogens at 50μg/mL in vitro, compounds 5g and 7c displayed nearly the same or higher fungicidal activities against some certain plant pathogens compared with the lead compound pyrimorph. A qualitative structure-activity
设计,合成和评估了一系列的1,1-二芳基叔醇及其一些脱水衍生物的抗真菌活性。在体外,某些化合物在50μg/ mL的浓度下对7种植物病原体表现出中等的抑制活性,与铅化合物pyrmorph相比,化合物5g和7c对某些植物病原体表现出几乎相同或更高的杀菌活性。定性结构-活性关系(SAR)分析表明,Cl取代基及其在吡啶环上的位置对于化合物的活性至关重要。特别是,几种化合物在体内以400mg / mL的浓度显示出对小麦白粉病或黄瓜炭疽的100%保护作用,这表明这些化合物可能是某些植物病害的潜在杀真菌剂。
