植物细胞内囊体中的D1蛋白酶是近年来发现的潜在的除草剂作用靶标. 以异噁唑甲酰赖氨酸脲先导结构信息为基础, 设计合成了未见报道的异噁唑甲酰赖氨酸类化合物11个. 目标化合物分子结构经IR, 1H NMR, 元素分析予以确证. 平皿法活体生物活性测试表明部分化合物具有中等除草活性; 化合物8h的离体生物活性测试表明其对D1蛋白酶有一定的抑制作用.

关键词: D1蛋白酶, 抑制剂, 异噁唑酰赖氨酸, 合成, 除草剂

Recently the D1 protease locating in the thylakoids of higher plants was found to be a potential herbicidal target. Based on one lead hit Nα-(isoxazol-5-ylcarbonyl)lysine of D1 protease inhibi-tors, a series of novel Nε-anilinocarbonyl-Nα-{3-[(un)substituted phenyl]isoxazol-5-ylcarbonyl}lysine derivatives were designed and synthesized, and their molecular struc-tures were verified with IR, 1H NMR, and elemental analysis. The biological activity examined in vivo demonstrated that most of the compounds exhibited moderate herbicidal activities. Mean-while, the enzyme activity of one compound 8h was tested against the spinach D1 protease and the result showed its inhibitive effect against the enzyme.

Key words: D1 protease, inhibitor, isoxazolecarbonyllysine derivative, synthesis, herbicide
