Abstract
Previously it was found that a conformationally rigid analogue (2) of the epilepsy drug vigabatrin (1) did not inactivate γ-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-mercaptoethanol. 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.Keywords
