of protectant activity against Erysiphe graminis f sp tritici (powdery mildew of wheat), but this did not improve the level of fungicidal activity against other diseases. In vitro activity against mitochondrial electron transport complex I (MET) derived from Ustilago maydis showed that 8-fluorolepidine analogues were moderately active at this target site, while the more fungicidally active 7- and 5
一系列新的(杂)芳氧基吡啶衍生物被设计为苯氧基喹啉和苯乙氧基喹啉化合物的杂化结构。这些靶标的合成需要开发几种衍生化4-羟甲基喹啉的新途径,并随后与酚或卤代芳烃偶联。在多种谷物疾病中,芳氧基leapidines通常表现出中等广谱的杀菌活性。在7位和/或5位上用氯取代喹啉环使分子具有针对小麦白粉病(小麦的白粉病)的高水平保护活性,但是这并未提高对其他小麦的杀真菌活性。疾病。体外对源自Ustilago maydis的线粒体电子传递复合物I(MET)的体外活性显示,在该目标位点,8-氟哌啶类似物具有中等活性,而更具杀真菌活性的7-和5,7-取代的化合物则无活性。这表明MET不是这些高活性粉状杀霉剂的主要目标。
