  摘要：

  合成了一系列具有零至三个双键（硬脂酰基，油酰基，亚油酰基和亚油酰基）的甘油脂的一系列14 C标记和未标记的二-γ-氨基丁酸酯。化合物的辛醇/水分配系数的测量结果表明，随着双键数量的减少（即，从亚油酰基到硬脂酰基）的增加。脑摄取指数从31.5（亚麻酸）上升到45.1（硬脂酰），类似地，脑渗透指数也从15（亚麻酸）上升到28（硬脂酰）。这些二-GABA脂酸酯的腹膜内注射以30 mg / kg的剂量对小鼠的一般运动活性产生了明显的抑制作用。活性最高的分子是含有两个和三个双键的分子，即亚油酰基和亚油酰基衍生物。

Finally, we used these standards to identify the AEL subtypes in shark and chimera liver oils. The distribution of the identified AEL were: 14:0 (20-24%), 16:0 (42-54%) and 18:1 (6-16%) and, to a lesser extent, (0.2-2%) for each of the following: 16:1, 17:0, 18:0, and 20:0. These
