  Structure-Based Design of a New Series of d-Glutamic Acid Based Inhibitors of Bacterial UDP-N-acetylmuramoyl-l-alanine:d-glutamate Ligase (MurD)

  摘要：

  MurD ligase is one of the key enzymes participating in the intracellular steps of peptidoglycan biosynthesis and constitutes a viable target in the search for novel antibacterial drugs to combat bacterial drug-resistance. We have designed, synthesized, and evaluated a new series of D-glutamic acid-based Escherichia colt MurD inhibitors incorporating the 5-benzylidenethiazolidin-4-one scaffold. The crystal structure of 16 in the MurD active site has provided a good starting point for the design of structurally optimized inhibitors 73-75 endowed with improved MurD inhibitory potency (IC50 between 3 and 7 mu M). Inhibitors 74 and 75 showed weak activity against Gram-positive Staphylococcus aureus and Enterococcus faecalis. Compounds 73-75, with IC50 values in the low micromolar range, represent the most potent D-Glu-based MurD inhibitors reported to date.
