DNA-templated click chemistry for creation of novel DNA binding molecules

We have developed a new methodology for producing new molecules that bind to dsDNA using DNA-templated click chemistry. The click reactions between the minor groove binding peptide and acridine intercalators were accelerated by the addition of dsDNA. Furthermore, the resulting peptide–acridine conjugate showed a slightly stronger binding to dsDNA. These results indicate that the DNA-templated click chemistry is applicable for screening new binding molecules.
