• Comparative Metabolomics and Structural Characterizations Illuminate Colibactin Pathway-Dependent Small Molecules
  作者：Maria I. Vizcaino、Philipp Engel、Eric Trautman、Jason M. Crawford

  DOI：10.1021/ja503450q

  日期：2014.7.2

  The gene duster responsible for synthesis of the unknown molecule "colibactin" has been identified in mutualistic and pathogenic Escherichia coli. The pathway endows its producer with a long-term persistence phenotype in the human bowel, a probiotic activity used in the treatment of ulcerative colitis, and a carcinogenic activity under host inflammatory conditions. To date, functional small molecules from this pathway have not been reported. Here we implemented a comparative metabolomics and targeted structural network analyses approach to identify a catalog of small molecules dependent on the colibactin pathway from the meningitis isolate E. coli IHE3034 and the probiotic E. coli Nissle 1917. The structures of 10 pathway-dependent small molecules are proposed based on structural characterizations and network relationships. The network will provide a roadmap for the structural and functional elucidation of a variety of other small molecules encoded by the pathway. From the characterized small molecule set, in vitro bacterial growth inhibitory and mammalian CNS receptor antagonist activities are presented.
• Recognition of Flexible Peptides in Water by Transition Metal Complexes

  DOI：10.1021/ol005555d

  日期：2000.4.1

  [GRAPHICS]This paper describes the design, synthesis, and evaluation of transition metal complexes capable of recognizing flexible histidine-containing peptides in aqueous medium (25 mM HEPES buffer, pH = 7.0, 25 degrees C). When the pattern of metal ions on a complex matches with the pattern of histidine moieties on the peptide, strong interaction (K = 1.2 x 10(6) M-1) can be achieved. The complex was highly selective (>200:1) in discriminating similar flexible peptides differing only by one glycine unit.
