1 the synthesis of two analogues of gamma-aminobutyric acid ( gaba ) , beta-chloro gaba and beta-phenyl gaba is described.2 the activity of brain gaba aminotransferase was inhibited by beta-chloro gaba ( 5.7 x 10 ( -5 ) m ) and beta-phenyl gaba ( 4.6 x 10 ( -3 ) m ) in a competitive manner with gaba.3 beta-chloro gaba exhibited 50 % of the inhibitory activity of gaba in blocking the discharge of the crayfish stretch receptor neurone ;
