title: Inhibition of high affinity uptake of GABA by branched fatty acids.
abstract: Several branched fatty acids including an antiepileptic agent nDPA were tested as potential inhibitors of high affinity uptake of GABA by brain slices and synaptosomes. Only three compounds (2-butyl-3-propylhexanoic acid, 5-propyloctanoic acid, 2-propylpenten-2-oic acid) were found to be relatively weak inhibitors of the uptake system. There was no correlation between anticonvulsant properties of the branched fatty acids and their potencies as inhibitors of high affinity uptake of GABA.
