Racemic 3-(p-totyl)-4-aminobutyric acid was obtained, resolved into enantiomers and their absolute configuration was determined. Both the racemic acid and two enantiomers were screened for CNS activity. R (+) enantiomers is 14--27-fold more effective than the S(-) one and 1.2--2.1 fold more effective than the racemate.
得到了外消旋3-(对甲苯基)-4-氨基丁酸,将其拆分为对映体并确定了它们的绝对构型。对外消旋酸和两种对映体进行了中枢神经系统活性筛选。R(+)对映体的效力比S(-)对映体高14至27倍,比对消旋体高1.2至2.1倍。
