Design, Synthesis, and Biological Activity of a Difluoro-Substituted, Conformationally Rigid Vigabatrin Analogue as a Potent γ-Aminobutyric Acid Aminotransferase Inhibitor
摘要:
Previously it was found that a conformationally rigid analogue (2) of the epilepsy drug vigabatrin (1) did not inactivate gamma-aminobutyric acid aminotransferase (GABA-AT), A cyclic compound with an exocyclic double bond (6) was synthesized and was found to inactivate GABA-AT, but only in the absence of 2-mereaptoethanol. The corresponding difluoro-substituted analogue (14) was synthesized and was shown to be a very potent time-dependent inhibitor, even in the presence of 2-mercaptoethanol.

(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.
