cycloalkylene moiety as well as other modifications in the lipophilic part. The in vitro values for inhibition of [(3)H]-GABA uptake in rat synaptosomes was determined for each compound, and it was found that several of the novel compounds inhibit GABA uptake as potently as their known symmetrical reference analogues. Several of the novel compounds were also evaluated for their ability to inhibit clonic seizures
在该实验室发布的先前一系列有效的GABA吸收抑制剂中,我们注意到已知的GABA吸收抑制剂(例如4 [1-(4,4-二苯基-3-丁烯基))中双芳族部分的取代方式不对称-3-哌啶羧酸]和5 [(R)-1-(4,4-双(3-甲基-2-噻吩基)-3-丁烯基)-3-哌啶羧酸]对高亲和力是有益的。这促使我们研究已知的对称GABA吸收抑制剂的不对称类似物,其中一个芳基已与烷基,亚烷基或亚环烷基部分以及亲脂部分中的其他修饰进行了交换。确定每种化合物在大鼠突触小体中抑制[(3)H] -GABA吸收的体外值,并且发现几种新颖的化合物与其已知的对称参考类似物一样有效地抑制了GABA的吸收。还评估了几种新型化合物在体内抑制15 mg / kg(ip)剂量的6,7-二甲氧基-4-乙基-β-咔啉-3-羧酸甲酯(DMCM)诱导的阵挛性癫痫发作的能力。某些化合物,例如18 [[R] -1-(2-((((1,2-双(2-氟
