以乙酰乙酸乙酯、原甲酸三乙酯、甲基肼等为原料,通过多步反应制备了一系列含吡唑的酰基脲类化合物.产物结构均经过1H NMR和HRMS确证;对所有化合物进行了杀菌活性测试,结果表明部分化合物对花生褐斑病菌、苹果轮纹病菌、水稻纹枯病菌、油菜菌核病菌具有较好的抑制效果,同时将高活性化合物7i与琥珀酸脱氢酶进行了对接,计算结果显示化合物7i能与琥珀酸脱氢酶形成稳定的复合物,化合物中的酰胺键能与酶中Ser39残基形成氢键作用.

关键词: 吡唑, 酰基脲, 合成, 杀菌活性, 分子对接

A series of novel acyl urea derivatives containing pyrazole moiety were synthesized from ethyl acetoacetate, triethyl orthoformate, methylhydrazine by multi-step reactions. Their structures were characterized by 1H NMR and HRMS spectra. The target compounds were evaluated for their fungicidal activity. The results indicated that some of the title compounds displayed certain fungicidal activities against Cercospora arachidicola, Sclerotinia sclerotiorum, Rhizoctonia solani and Physalopora piricola. The docking results indicated the hydrogen bond formed between the amide group and Ser 39 residue.

Key words: pyrazole, acyl urea, synthesis, fungicidal activity, docking
