The chemistry underpinning oligonucleotide peptide conjugation is diverse and continually being refined. One of the most explored and historically significant strategies for conjugation of a peptide with an oligonucleotide is through an amide linkage. This involves the reaction of an amino group on one molecule with an activated carboxyl group on the other. Beyond amide bonds, other chemical strategies are widely employed for forming a covalent bond between peptide and oligonucleotide fragments.A peptide oligonucleotide conjugate (POC) is a complex biomolecule that brings together two distinct components: peptides and oligonucleotides. These include the use of oxime, thiazolidine, and hydrazine groups, offering alternative pathways for creating stable linkages. Recent advancements have also introduced more efficient and sustainable approaches, such as catalytic methods for preparing POCs linked with an amide bond, demonstrating a move towards greener chemistry in bioconjugation. Native chemical ligation (NCL) has also emerged as an efficient strategy for synthesizing specific types of oligonucleotide-peptide conjugates, such as CPP-ASO conjugates, where CPP stands for cell-penetrating peptide.

The applications of peptide-oligonucleotide conjugates are rapidly expanding, spanning various therapeutic areas and research domains. Their ability to combine the targeting and delivery capabilities of peptides with the specific molecular recognition and therapeutic potential of oligonucleotides makes them invaluable tools.Peptide-oligonucleotide conjugatesare molecular composites containing a nucleic acid moiety covalently linked to a polypeptide moiety.
