３，４－二氯苯丙烯酰另丁胺（７９０３）是一种新的桂皮酰胺类抗惊药，本实验研究了７９０３对γ－氨基丁酸摄取与释放过程的影响，结果发现７９０３对小鼠脑勺浆、突触体及原代培养的胚鼠大脑皮层神经细胞的γ－氨基丁酸的摄取过程无明显影响，而７９０３在１０－４、１０－５ｍｏｌ·Ｌ－１浓度时，可明显促进小鼠脑实触体和原代培养的胚鼠大脑皮层神经细胞γ－氨基丁酸的释放。 3,4-Dichlorophenyl acryloyl butylamine (7903) is a novel cinnamic amide anticonvulsant. In this experiment, the effect of 7903 on the uptake and release of γ-aminobutyric acid was studied. The results showed that 7903 was small There was no significant effect on the uptake of γ-aminobutyric acid from the cerebrospinal fluid, synaptosomes and primary cultured cerebral cortex neurons, while 7903 at 10-4,10-5 mol·L-1 concentration Promote the release of γ-aminobutyric acid from the cerebral parenchyma of mouse and the primary culture of embryonic rat.
