  Chemoselective Peptidomimetic Ligation Using Thioacid Peptides and Aziridine Templates

  摘要：

  Chemoselective peptidomimetic ligation has been made possible using thioacid peptides and NH aziridine-terminated amino acids and peptides. In the course of this reaction, a reduced amide bond is incorporated into the backbone of a peptide. This process enables incorporation of reduced cysteine, reduced substituted cysteine, reduced phenylalanine, and reduced alanine. Our method should be adaptable to other unnatural amino acid residues at the ligation site. Experiments aimed at evaluating the chemoselectivity of this process in the presence of competing thiol nucleophiles suggest high specificity at micromolar concentrations. This holds even in the presence of glutathione, which neutralizes xenobiotic electrophiles in cells.

• Epimerization- and Protecting-Group-Free Synthesis of Peptidomimetic Conjugates from Amphoteric Amino Aldehydes
  作者：Xinghan Li、Andrei K. Yudin

  DOI：10.1021/ja076155p

  日期：2007.11.1

  We have developed a novel protecting-group-free strategy for the synthesis of peptidomimetic conjugates. The high degrees of stereocontrol and chemoselectivity achieved in this chemistry hinge upon unusual preferences of the amphoteric amino aldehydes. The resulting conjugates contain reduced amide bonds at defined positions, offering a possibility for peptidomimetic ligation. These findings should allow access to templates for introducing both natural and unnatural amino acid residues in close proximity to the reduced amide bond isosteres.
