【摘要】 报道了Ｎ－苯磺酰基磷酰二胺酯类化合物的合成。用电生理细胞内微电极技术研究了这些化合物的结构对昆虫谷氨酸电位阻断作用的影响。结果表明：它们均能阻断果蝇幼虫神经肌肉兴奋性接点电位，但其阻断时间相差很大。阻断过程可分为３种：（１）电位逐渐被阻断；（２）电位开始有短暂的兴奋，然后被阻断；（３）电位迅速被阻断。活体实验表明：具有第２种杀虫机制的化合物杀虫效果最好．更多还原

【Abstract】 The synthesis of N-phenylsulfonyl phosphordaimides was reported.The effects of the structures of the compounds on the insect glutamate potentials were investigated by using electrophysiological intracellular microelectrode recording technique. The results showed that all of the compounds could block the neuromuscular junctional excitation potentials (EJP),but the blocking time had a great difference. The blocking action could be divided into three types:(1)EJP were blocked progressively;(2)EJP were blocked after a short exciting period;(3)EJP were blocked rapidly. The results of the bioassay showed that the compounds which possessed the second action mechanism had the best killing effect.更多还原
