synthesis of 21 novel esters derived from norbornadiene and evaluation of their potential activity against Meloidogyne javanica. The esters 5-25 presented 50% mortality of the nematodes. The acid 3 and the ester 4 caused 96 and 93% mortality of the nematodes, respectively. The lethal concentration to kill 50% of the nematodes (LD50) were determined as being 11.8 μg mL for the acid 3 and 99.4 μg mL for the
线虫是农业中的主要问题,控制这种害虫的有效方法是通过化学防治,但是市场上存在的有效分子对哺乳动物和鸟类具有很大的毒性。因此,不断需要开发新的杀线虫剂分子。这项研究描述了21种衍生自降冰片二烯的新型酯的合成以及它们对爪哇根结线虫的潜在活性的评估。酯5-25表示线虫的死亡率为50%。酸3和酯4分别导致线虫的死亡率为96%和93%。杀死50%线虫的致死浓度(LD50)被确定为酸3为11.8μgmL,酯4为99.4μgmL。
