摘　　要：Aspernigerin是从狗牙根内生菌Aspergillus niger IFB-E003的培养液中分离得到的天然产物,对癌细胞具有较强的活性.设计了一条全新的合成路线,以1,2,3,4-四氢喹啉和氯乙酰氯为主要原料,经过两步反应合成了Aspernigerin,总收率80.3%,较文献报道的合成路线的总收率提高了33%.首次对Aspernigerin进行农用生物活性测试,结果表明,Aspernigerin具有一定的杀菌、杀虫活性和除草活性,在600和200μg/mL的浓度下对小菜蛾的杀虫活性分别为100%和75%,在500μg/mL的浓度下对稗草、小麦、黄瓜的根、茎的生长抑制率都在90%以上.Aspernigerin is a natural product originally isolated from the extract of a culture of aspergillus niger IFB-E003,an endophyte in cyndon dactylon,and has been shown to be cytotoxic to the tumor cell lines.A facile total synthetic method for preparing aspernigerin from starting material 1,2,3,4-tetra-hydroquinoline and chloroacetyl chloride in two steps was reported.The total yield was 80.3% which increased 33% compared with the method of reference.The pesticide biological activity of aspernigerin was tested for the first time.The result indicated that aspernigerin exhibited certain fungicidal activities,insecticidal activities and herbicidal activities.Especially,the insecticidal activities against Plutella xylostella were 100% and 75% at the concentration of 600 and 200 μg/mL,respectively.The herbicidal activities against Echinochloa Crusgalli,Triticum aestivum and Cucumis sativus were all higher than 90% at the concentration of 500 μg/mL.
