title: 3-(p-tolyl)-4-aminobutanoic acid synthesis, resolution into enantiomers and pharmacological activity.
abstract: 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.
