Abstract
Bis(guanidinium)alcohols have been designed to react with phosphodiester substrates in a fast transphosphorylation step, a quasi-intramolecular process taking place in contact ion pairs. Here the attachment of such compounds to Dervan-type hairpin polyamides is described. The resulting conjugate 1 binds to AT-rich DNA duplexes with affinity similar to that of the parent polyamide as shown by UV melting experiments and CD titrations. Conjugate 1 nicks plasmid DNA at concentrations ranging from micromolar to high nanomolar.
