| Outline of Final Research Achievements |
The synthesis of new β-Lys PNA monomers and their incorporation into a 10-residue PNA sequence have been achieved. PNA containing β-Lys PNA units formed a stable hybrid duplex with DNA. However, incorporation of β-Lys PNA units caused destabilization of PNA-DNA duplexes to some extent. Electrostatic attractions between β-PNA and DNA could reduce this destabilization effect. Subsequently, bipyridine-conjugated β-Lys PNA was prepared and exhibited sequence selective cleavage of DNA. Based on the structures of the cleavage products and molecular modeling, we reasoned that bipyridine moiety locates within the minor groove of the PNA-DNA duplexes. The lysine side chain of β-PNA is a versatile handle for attaching various functional molecules.
