在2-苯甲酰基嘧啶类化合物结构优化结果基础上, 定向设计合成了8个2-(吡啶-2-甲酰基)嘧啶类化合物, 并对其进行了室内杀菌活性测定, 结果表明这类化合物对黄瓜白粉病和黄瓜霜霉病有很好的防效. 对高活性化合物6b深入筛选结果表明: 6b对黄瓜白粉病有较好的预防和治疗活性, 预防活性的EC50和EC90值分别为0.69和2.89 mg/L, 治疗活性EC50和EC90值分别为0.13和1.6 mg/L, 与对照药剂苯菌酮相当. 2-氯-N-{[2-(4,6-二甲氧基嘧啶-2-甲酰基)吡啶-3-基]氧基}-N-甲基苯甲酰胺(6b)具有向上传导活性和较好的耐雨淋作用, 持效期为15~20 d.

Based on the structural optimization of 2-benzoyl pyrimidine derivatives, eight 2-(pyridyl-2-formyl)pyrimidine derivatives have been specifically designed and synthesized for evaluation of their interior fungicidal activities. 2-(Pyridyl-2-formyl)pyrimidine derivatives show excellent activity against cucumber downy mildew and cucumber powdery mildew. Among them, 2-chloro-N-{[2-(4,6-dimethoxypyrimidine-2-carbonyl)pyridin-3-yl]oxy}-N-methylbenzamide (6b) exhibits comparable protective and curative activity against cucumber powdery mildew to reference Metrafenone. EC50 and EC90 of the protective activity are 0.69 and 2.89 mg/L, respectively, and those of curative activity are 0.13 and 1.6 mg/L. 6b also shows excellent upward translocation in plants and rainfast performance. Especially, its persistent efficacy period of the protective activity against cucumber powdery mildew can last 15~20 d.
