Peptide-Nucleic Acid Conjugation Ahead

Developments in peptide-nucleic acid conjugates are enabling novel means of drug delivery capable of passing the cell membrane, with exciting consequences for the future of RNA therapeutics.

Advances in peptides and nucleic acids synthesis are promoting the development of bioconjugates, where these molecules are either cross-linked to each other or to other compounds to yield products with distinct properties. There are many applications in biomedicine where linking two active molecules can lead to up- or down-regulation of gene expression. These bioconjugates are not limited to peptide-nucleic acid derivatives, but either of these two moieties can be substituted by another compound such as a polysaccharide, lipid, synthetic polymer or small molecules. Depending on the bioconjugates’ nature they can have applications in qualitative/quantitative assays, targeting of specific cells for diagnostic and/or therapeutic purposes, transfer of compounds across cell membranes, modulation of certain biological activities and other uses.
