title: Phosphono peptide nucleic acids with a constrained hydroxyproline-based backbone.
abstract: DNA mimics representing negatively charged analogues of peptide nucleic acids (PNAs), particularly hetero-oligomers constructed from alternating phosphono-PNA residues (pPNA) and monomers on the base of trans-4-hydroxy-L-proline (HypNA) as well as mimics composed of phosphono-HypNA monomers (pHypNA) were tested in a set of in vitro and in vivo assays, and they demonstrated a high potential for the use in nucleic acid based diagnostic, isolation of nucleic acids and antisense experiments.
