Conformationally-restricted vigabatrin analogs as irreversible and reversible inhibitors of γ-aminobutyric acid aminotransferase
摘要:
Compounds that inhibit gamma-aminobutyric acid aminotransferase exhibit anticonvulsant activity; vigabatrin is a known irreversible inhibitor of this enzyme and anticonvulsant drug. Conformationally-restricted, five-membered- and six-membered-ring vigabatrin analogs were synthesized and tested as inhibitors of gamma-aminobutyric acid aminotransferase. Two monofluorinated compounds, 4 and 5, are time-dependent inhibitors of the enzyme, and their potencies are comparable to that of vigabatrin. Compounds 6 and 7 are weak reversible inhibitors.

(1S, 3S)-3-Amino-4-difluoromethylene-1-cyclopentanoic acid illustrates a novel class of compounds as potent irreversible inhibitors of &ggr;-aminobutyric acid aminotransferase (GABA-AT). The corresponding monofluoro-substituted compounds also are potent time-dependent inhibitors of GABA-AT.
