Several optically active N-(indol-3-ylglyoxylyl)amino acid derivatives were synthesized and tested for [3H]flunitrazepam displacing activity in bovine brain membranes. IC50 values were measured and revealed that the D form of the amino acid moiety of the compounds was more potent than both the L form and racemic form, suggesting a key role of the amino acid stereochemistry on the affinity to the benzodiazepine
合成了几种旋光性的N-(吲哚-3-基乙二醛基)氨基酸衍生物,并测试了牛脑膜中[3H]氟硝西m的置换活性。测量IC 50值,发现化合物的氨基酸部分的D形式比L形式和外消旋形式都更有效,这表明氨基酸立体化学在与苯二氮卓受体的亲和力中起着关键作用。报告的最具活性的化合物的GABA比率和前惊厥药/惊厥药数据表明,它们在苯并二氮杂receptor受体上起反向激动剂的作用。
