derivatives were designed, synthesized, and characterized by 1H NMR, 13C NMR, and HRMS. The fungicidal activities of these new compounds against Sclerotinia sclerotiorum, Botrytis cinereal, and Colletotrichum fragariae were evaluated. The results indicated that compounds 5b, 5f, and 5g displayed potential fungicidal activities against tested fungi, especially 5f exhibited IC50 value of 28.9 mg/L against
设计、合成了 12 种 N-((2-phenyloxazol-4-yl)methyl) 嘧啶甲酰胺衍生物,并通过以下方法表征1核磁共振氢谱,13C 核磁共振和 HRMS。这些新化合物的杀菌活性菌核病菌, Botrytis cinereal, 和草莓炭疽病菌进行了评估。结果表明,化合物 5b、5f 和 5g 对受试真菌具有潜在的杀菌活性,特别是 5f 表现出 IC50值 28.9 毫克/升对核盘菌. 此外,化合物 5f 和 5g 显示出 IC5054.8 毫克/升和 62.2 毫克/升对C. fragariae分别表明它们比商业杀菌剂恶霉灵更有效。讨论了表面的构效关系,可能有利于杀菌剂的开发和新型杀菌剂的发现。
