isomers have little affinity for GABA receptors in vitro relative to GABA agonists. However, expected but weak stereoselective activity was observed when these analogues were assessed for their ability to inhibit high-affinity [3H]GABAuptake into rat brain synaptosomes. These data are discussed in light of structure-activity studies of other neurotransmitter analogues, and a preliminary hypothesis based
描述了两个包含= N(C)3CO2H(γ-氨基丁酸; GABA)部分的顺式-十氢喹啉-5-羧酸差向异构体(1和2)的合成。分子内和分子间[4 + 2]环加成反应均用于构建关键中间体。1 H NMR研究为两种非对映异构体的优选溶液构象提供了证据。药理研究表明,相对于GABA激动剂,这些异构体对GABA受体的体外亲和力很小。但是,当评估这些类似物抑制大鼠脑突触体中高亲和力[3H] GABA摄取的能力时,观察到了预期的但较弱的立体选择性活性。根据其他神经递质类似物的结构活性研究讨论了这些数据,
