development of pesticides. In this project, the target compounds containing 4-quinolone and piperazine substructures based on waltherione F were synthesized through the combination of the fungicidal amide lead compound X-I-4 discovered in our previous work and various of fungicidal piperazine derivatives. Screening of their biological activities suggested that products I-3, I-5, II-3, II-7, II-10, II-11
基于天然产物的结构优化已成为开发新型杀菌剂的有效途径,对践行新发展理念、推动农药绿色发展具有重要指导意义。本项目将我们前期工作中发现的杀菌酰胺类先导化合物X - I - 4与多种杀菌哌嗪衍生物结合,合成了基于沃尔瑟酮F的含有4-喹诺酮和哌嗪亚结构的目标化合物。对其生物活性的筛选表明产物I - 3 , I - 5 , II - 3 ,II - 7、II - 10、II - 11和II - 13对立枯丝核菌的抑制率高于其他受试化合物。体外细胞细胞毒性试验表明,化合物II - 6和II - 11对 HepG2 的细胞毒性比其他测试化合物高。荧光特性研究表明,化合物I - 6的甲醇溶液的绝对荧光QY值高于I-。2 , I - 3 , I - 7和I - 8 , 由 TD-DFT 进一步阐明。
