The defining characteristic of peptide nucleic acids is their replacement of the natural sugar-phosphate backbone with a neutral, pseudopeptide polymer, typically composed of N-(2-aminoethyl) glycine (aeg) repeating units.作者：V MacLelland·2024·被引用次数：36—Peptide nucleic acids (PNAs) aresynthetic nucleic acid analogswith a neutral N-(2-aminoethyl) glycine backbone. This structural modification imbues PNA with remarkable chemical, physical, and binding properties, surpassing those of natural nucleic acids in several key areasSynthesis of Peptide-Peptide Nucleic Acid Conjugates.

The core principle behind peptide nucleic acid technology lies in its ability to retain the crucial base-pairing capabilities of DNA and RNA. Nucleobases—adenine (A), guanine (G), cytosine (C), and thymine (T) or uracil (U)—are directly attached to this peptide-like backbone, allowing PNAs to bind to complementary sequences of DNA, RNA, or even other PNAs with high affinity and specificity. This makes PNAs powerful tools for molecular recognition and manipulation. Unlike natural nucleic acids, which carry a negative charge due to the phosphodiester backbone, PNA is charge-neutral, contributing to its enhanced stability and reduced non-specific interactions.

In diagnostics, PNA is employed as a probe in techniques like fluorescent in-situ hybridization (FISH) and microarrays, enabling faster and more accurate cancer diagnosis compared to traditional methods. The PNA-Pdx toolkit, for instance, offers specialized diagnostic tools for nucleic acid and single nucleotide polymorphism (SNP) detection. Furthermore, PNA plays a role in modulating polymerase chain reaction (PCR) reactions, including PCR reaction modulation/mutation, and is utilized in many in-vitro assays. The development of cell-penetrating peptide conjugates of peptide nucleic acids is also enhancing their utility in cellular and in-vivo applications, showing potential for inhibiting specific cellular processes.作者：S Montazersaheb·2018·被引用次数：95—Peptide nucleic acids (PNA) aresynthetic analog of DNAwith a repeating N-(2-aminoethyl)-glycine peptide backbone connected to purine and ...

Beyond diagnostics, peptide nucleic acid technology holds immense promise for therapeutic interventions. PNAs are being explored as potent therapeutic agents for a range of genetic, acquired, and viral diseases. Their ability to bind to specific RNA or DNA sequences allows them to act as antisense agents, interfering with gene expression or viral replication. This has led to investigations into their use in antimicrobial therapy, where PNAs can target essential bacterial genes. The enhanced chemical, physical, and binding properties of PNAs contribute to their stability and effectiveness *in vivo*, although potential long-term toxicity remains an area of consideration, as highlighted in reviews of recent patents and applicationsPeptide Nucleic Acid | Encyclopedia MDPI.
