Abstract:
:DL-(1-Amino-2-propenyl)phosphonic acid was synthesized through the sequential oxidation, sulfoxide elimination, and deprotection of diphenyl [1-[(benzyloxycarbonyl)amino]-3-(phenylthio)propyl] phosphonate. This analogue of vinylglycine is a strong inhibitor of the alanine racemases from Pseudomonas aeruginosa and Streptococcus faecalis and of the D-Ala:D-Ala ligase from this latter species. This molecule is ineffective against the whole bacterial cells. Unlike vinylglycine, this unsaturated phosphonate does not inhibit the following mammalian enzymes: aspartate aminotransferase, alanine aminotransferase, D-amino acid oxidase, which indicates its specificity. Thus, its incorporation in a peptide structure could induce interesting antimicrobial properties.
