title: Peptide nucleic acid-metal complex conjugates: facile modulation of PNA-DNA duplex stability.
abstract: Conjugates of peptide nucleic acids (PNA) and metal binding ligands were prepared using solid-phase synthesis. Stability of duplexes of bis-picolylamine-PNA conjugates and DNA was found to be modulated by equimolar concentrations of bioavailable metal ions: Ni(2+), Zn(2+)>Cu(2+). Sequence specificity of PNA was not compromised in the presence of these metal ions.
