  Synthesis of Modified Peptidoglycan Precursor Analogues for the Inhibition of Glycosyltransferase

  摘要：

  The peptidoglycan glycosyltransferases (GTs) are essential enzymes that catalyze the polymerization of On OH glycan chains of the bacterial cell wall from lipid II and thus constitute a validated antibacterial target. Their enzymatic cavity is composed of a donor site for the growing glycan chain (where the inhibitor moenomycin binds) and an acceptor site for lipid II substrate. In order to find lead inhibitors able to fill this large active site, we have synthesized a series of substrate analogues of lipid I and lipid II with variations in the lipid, the pyrophosphate, and the peptide moieties and evaluated their biological effect on the GT activity of E. coli PBP1b and their antibacterial potential. We found several compounds able to inhibit the GT activity in vitro and cause growth defect in Bacillus subtilis. The more active was C16-phosphoglycerate-MurNAc-(L-Alao-D-Glu)-GIcNAc, which also showed antibacterial activity. These molecules are promising leads for the design of new antibacterial GT inhibitors.

  日期：2001.7.1

  A total synthesis of lipid I (4), a membrane-associated intermediate in the bacterial cell wall (peptidoglycan) biosynthesis pathway, is reported. This highly convergent synthesis will enable further studies on bacterial resistance mechanisms and may provide insight toward the development of new chemotherapeutic agents with novel modes of action.

• Characterization of a transglycosylase domain of Streptococcus pneumoniae PBP1b
  作者：Haitian Liu、Chi-Huey Wong

  DOI：10.1016/j.bmc.2006.06.058

  日期：2006.11

  Inhibitors of transglycosylases may serve as potent antibiotics that are less prone to resistance development in bacterial pathogens. To facilitate the search of such compounds, a transglycosylase (TGase) domain of the membrane integral multidomain Streptococcus pneumoniae PBP1b was cloned and expressed. This TGase domain was characterized by a substrate-dependent fluorescence coupled enzyme assay and an inhibitor-tethered surface plasmon resonance binding assay. Both assays show that the catalytic efficiency of the domain is comparable to that of the monofunctional transglycosylases, and it is fully active in the absence of other domains. The isolation of the active TGase domain makes it possible to screen for potential antibiotics targeting transglycosylases. (c) 2006 Elsevier Ltd. All rights reserved.
