Structural pre-organization of peptide nucleic acids.
Introduction of constraint via chemical bridging in the aegPNA leads to the five or six membered cyclic structures that may contribute towards maintaining the balance between rigidity and flexibility of the PNA backbone. The significant promise of our approach to use the naturally occurring trans-4-hydroxy-L-proline to arrive at different chirally pure cyclic PNA analogs and their DNA binding properties will be presented.
