Labeled and unlabeled aliphatic and steroid esters of gamma-amino[U-14C]butyric acid (GABA) were synthesized and tested for their capacity to penetrate the blood-brain barrier and for evidence of central neuropharmacological activity in rodents. The uptake of the labeled 9,12,15- octadecatrienyl ( linolenyl ), 3-cholesteryl, 1-butyl, and the 9-fluoro-11 beta,17-dihydroxy-16 alpha-methyl-3,20- dioxopregna
合成了标记和未标记的γ-氨基[U-14C]丁酸(GABA)的脂族和甾族酯,并测试了它们穿透血脑屏障的能力以及啮齿动物中枢神经药理活性的证据。摄取标记的9,12,15-十八碳三烯基(亚油基),3-胆固醇基,1-丁基和9-氟-11β,17-二羟基-16α-甲基-3,20-二氧杂戊烷-1, GABA进入小鼠大脑的4-dien-21-基(地塞米松)酯分别比GABA增加2倍,25倍,74倍和81倍。GABA的胆固醇酯以剂量依赖的方式抑制了小鼠和大鼠的一般运动活动,而1-丁基酯,亚麻烯基酯和地塞米松酯则没有活性。研究水解速率,GABA受体结合能力,
