title: Syntheses and kinetic evaluation of hydroxamate-based peptide inhibitors of glyoxalase I.
abstract: Hydroxamate-containing tripeptide analogs resembling a reactive intermediate in glyoxalase I catalysis were prepared by solution methods and were found to be competitive inhibitors of the enzyme from Saccharomyces cerevisiae. Electronic properties of the hydroxamate functionality as well as those of the expected intermediates in the enzyme-catalyzed reaction were compared.
