| 摘 要： | 以靛红酸酐为起始原料,设计并合成了14个结构新颖的吡啶联喹唑啉酮类衍生物。所有化合物经1H NMR、13 C NMR和高分辨质谱(HRMS)表征确证其结构。初步抗菌活性结果显示,该类化合物对水稻白叶枯病菌(Xanthomonas oryzae pv.Oryzae,Xoo)、猕猴桃溃疡病菌(Pseudomonassyringae pv.actinidae,Psa)和玉米纹枯病菌(Rhizoctonia solani,Rs)均表现出一定的抑制活性。其中化合物2-(3,3′-联吡啶]-5-基)-6-氯-3,8-二甲基喹唑啉-4(3 H)-酮(3m)对Rs的抑制活性可达(51.8%)。

| Abstract: | Fourteen pyridylquinazolone derivatives with novel structures were designed and synthesized from indic anhydride.Their structures were confirmed by 1H NMR,13 C NMR and high resolution mass spectrometry(HRMS).The preliminary results showed that these compounds had certain inhibitory activities against Xanthomonas oryzae pv.Oryzae(Xoo),Pseudomonas syringae pv.Actinidae(Psa)and Rhizoctonia solani(Rs).The inhibitory activity of compound 3m against Rs was 51.8%. |
