  Synthesis of Conformationally Preorganized and Cell-Permeable Guanidine-Based γ-Peptide Nucleic Acids (γGPNAs)

  摘要：

  A general method for preparing optically pure guanidine-based gamma-peptide nucleic acid (gamma GPNA) monomers for all four natural nucleobases (A, C, G, and T) is described. These second-generation gamma GPNAs differ from the first-generation GPNAs in that the guanidinium group is installed at the gamma- instead of the alpha-position of the N-(2-aminoethyl)glycine backbone unit. This positional switch enables GPNAs to be synthesized from relatively cheap L- as opposed to D-amino acids. Unlike their (x-predecessors, which are randomly folded, gamma GPNAs prepared from L-amino acids are preorganized into a right-handed helix and bind to DNA and RNA with exceptionally high affinity and sequence selectivity and are readily taken up by mammalian cells.
