Oligonucleotides: These are short, single-stranded DNA or RNA molecules, also known as oligomers. They are composed of nucleotides linked by phosphodiester bonds. Oligonucleotides are fundamental to cellular processes, serving as components of DNA and RNA. In therapeutic and research applications, oligonucleotides are designed to interact with specific genetic sequences, influencing gene expression or function. Technologies like antisense technology utilize oligonucleotides to develop gene-specific therapies. Examples include antisense oligonucleotides (ASOs) and locked nucleic acids (LNAs), which offer enhanced stability and binding affinity.Chemistry of Peptide-Oligonucleotide Conjugates: A Review The ability of oligonucleotides to recognize and bind [to] specific DNA or RNA sequences makes them powerful tools for gene silencing or modulation.

The Power of Conjugation: Peptide-Oligonucleotide Hybrids

The true innovation often lies in the synergy achieved by combining these two classes of molecules.作者：C Lou·2016·被引用次数：67—Here, we show the applicability ofpeptide–oligonucleotide conjugatesfor self-assembly of higher-ordered protein-like structures. Peptide-oligonucleotide conjugation refers to the covalent linkage of a peptide to an oligonucleotide. This approach offers a multitude of advantages, addressing some of the inherent limitations of each molecule when used independently.

One of the primary benefits of peptide-oligonucleotide conjugates (POCs) is enhanced stability. The conjugation of peptides to the oligonucleotide can protect them from degradation by nucleases present in the bloodstream or cellular environments. This protection significantly extends the in vivo half-life of the oligonucleotide, allowing for sustained therapeutic effects. Furthermore, the peptide component can also bind to proteins on the surface of cells, facilitating targeted delivery of the oligonucleotide to specific tissues or cell types.Peptide Oligonucleotide Conjugates for Life Science ... This targeted delivery improves efficacy and reduces off-target effects, a significant challenge in traditional drug development.

Peptide-oligonucleotide conjugates also offer a means to enhance cellular uptake. While oligonucleotides can struggle to cross cell membranes, certain peptides, particularly cell-penetrating peptides (CPPs), possess the ability to facilitate entry into cells作者：T MacCulloch·2019·被引用次数：78—Peptide–oligonucleotide conjugates (POCs) are covalent constructs that link a molecule like DNA to a syntheticpeptidesequences..
