Abstract

The design, synthesis, and evaluation of novel gamma-aminobutyric acid aminotransferase (GABA-AT) inhibitors and inactivators can lead to the discovery of new GABA-related therapeutics. To this end, a series of aromatic amino acid compounds was synthesized to aid in the design of new inhibitors and inactivators of GABA-AT. All compounds were tested as competitive inhibitors of GABA-AT. The amino acids with benzylic amines were also tested as substrates for GABA-AT. It was found that these compounds were all poor competitive inhibitors of GABA-AT, but some were substrates of the enzyme, suggesting their utility as scaffolds for potential GABA-AT mechanism-based inactivators. Computer modeling was used to rationalize the substrate activity of the various compounds.
