Synthesis of 2-Aminopyridine-Modified Peptide Nucleic Acids.

This article discusses the synthesis of 2-aminopyridine-modified peptide nucleic acids (PNAs) and their potential applications in research and diagnostics. PNAs are known for their high affinity and sequence specificity in binding to nucleic acids. The article describes the chemical modifications made to improve the properties of PNAs, such as replacing cytosine with pseudoisocytosine and using 2-aminopyridine as an alternative. The authors also outline the optimized synthetic route to produce the modified PNA monomers. The article provides detailed procedures and recommendations for the synthesis of PNAs using different synthesizers. Overall, the article offers valuable insights for researchers interested in the synthesis and applications of modified PNAs. [Extracted from the article]
