含肟醚的姜黄素衍生物的合成及生物活性研究

Synthesis and Biological Activity of Oxime Ethers of Curcumin Derivatives

采用活性拼接原理,将肟醚引入到含杂环的姜黄素衍生物1,4-戊二烯-3-酮结构中,合成了一系列新的1-芳基-5-杂环-1,4-戊二烯-3-酮肟醚类化合物,其结构经IR,1H NMR,13C NMR,ESI-MS和元素分析确认.初步生物活性测试结果表明:在药剂浓度为500μg/mL时,目标化合物具有一定的抗烟草病毒(TMV)活性.

On the principle of biologically active factor splicing, curcumin derivatives introduced active functional group oxime ethers into the structure of 1,4-pentadien-3-one. A series of new 1-phenyl-5-heterocycle-1,4-pentadien-3-one oxime ethers were synthesized, and their structures were identified by IR, 1H NMR, 13C NMR, ESI-MS and elemental analysis. The preliminary bioassay results indicated that target compounds showed certain antiviral activity against TMV at a concentration of 500μg/mL.
