Background:

• Peptide nucleic acids (PNAs) are DNA mimics with unique binding properties.
• Developing novel PNA analogues with improved characteristics is crucial for advancing molecular diagnostics and therapeutics.
• Existing PNA analogues have limitations that necessitate the exploration of new chemical scaffolds.

Purpose of the Study:

• To design and synthesize novel negatively charged DNA mimics based on phosphonate analogues of peptide nucleic acids (PNAs).
• To evaluate the physicochemical and biological properties of these novel phosphonate-containing PNA derivatives.
• To compare their performance against natural oligonucleotides, classical PNAs, and morpholino phosphorodiamidate analogues.

Main Methods:

• Chemical synthesis of phosphonate-containing PNA analogues.
• Characterization of physicochemical properties (e.g., charge, stability).
• Biological evaluation including assessment of potential applications in diagnostics and gene expression inhibition.

Main Results:

• Successful design and synthesis of negatively charged phosphonate-containing PNA derivatives.
• Demonstration of favorable physicochemical properties for the novel PNA analogues.
• Evidence of high potential for applications in diagnostics, nucleic acid analysis, and gene expression inhibition.

Conclusions:
