New peptide nucleic acid analogues: synthesis and applications.
Peptide nucleic acids are oligonucleotide mimics characterised by high chemical and enzymatic stability, high specificity and affinity toward complementary DNA/RNA. The lack of charge and polar groups in the backbone decrease their solubility in aqueous environment and their ability to cross cell membranes, reducing their performance in in vivo applications. To improve solubility, increase affinity and specificity of binding and to control recognition between nucleic acids, several analogues bearing modifications on the nucleobase, nucleobase-backbone linker and on the backbone were synthesised. This paper describes the synthesis and applications of Peptide nucleic acid analogues and discusses the potential of analogues for which no application is reported.
