摘要:
                                Diaminopimelic acid is an essential amino acid in the peptidoglycan of Gram-negative bacteria, mycobacteria and some Gram-positive bacteria.  It can be used as a target for the development of antibacterial agents.  In this article the synthesis of a series of phosphonic acid analogues of this diamino-dicarboxylic acid is described:  mono- and diphosphonic acid derivatives as well as their homologues, N-alkyl analogues and some peptidyl derivatives.  A phenylphosphinic derivative was also prepared.  All the prepared compounds were tested for their antibacterial activity against a series of Gram-positive, Gram-negative and mycobacteria.  They were also tested as possible inhibitors of the UDP-MurNAc-L-Ala-gamma-D-Glu:  meso-DAP synthetase.  No significant biological activity was found.
