Introduction
Peptide nucleic acid (PNA) is a unique compound with a neutral amide backbone and combined peptide and nucleic acid properties. PNA can bind to DNA and RNA with high affinity and sequence specificity, forming a heterodimeric complex with high thermal stability and unique resistance to ionic strength changes.

Synthesis of PNA Monomers
A variety of building blocks have been used to synthesize PNA and its analogs, including backbone structures, attachment of chiral and non-chiral groups to N-(2-aminoethyl) glycine, types of bases, etc.
Classic PNA Backbone Synthesis Method
- Alkylation reaction
- Reduction reaction of Schiff base
- Mitsunobu reaction
Introduce Bases into the Backbone
All four bases are alkylated by amines to form base acetic acid derivatives (thymine acetic acid, cytosine acetic acid, adenine acetic acid, and guanine acetic acid), which are then linked to the unprotected nitrogen on the backbone using the usual method of peptide synthesis.
PNA Intermediates

Advantages of PNA
- PNA cannot be degraded by nucleases and proteases
- PNA binds well to DNA and RNA with high specificity
- The stability of PNA binding to RNA is much higher than that of binding to DNA
- The PNA2/DNA triple helix structure formed by PNA and DNA can cause transcriptional arrest, and the PNA2/RNA formed by PNA and RNA can cause translational arrest
Applications of PNA
- Telomerase inhibitors
- Anti-HIV
- For the treatment and research of gene-related disorders of the central nervous system
- Drug carriers
- DNA diagnostics
- Labeling plasmid DNA vectors, target peptides, etc.
- PCR
