Peptide Nucleic Acid

Acta Informatica Medica, 2011
Peptide nucleic acid (PNA) is a nucleic acid analog in which the sugar phosphate backbone of natural nucleic acid has been replaced by a synthetic peptide backbone usually formed from N-(2-amino-ethyl)-glycine units. It is chemically stable and resistant to hydrolytic enzyme cleavage and thus not expected to be degraded inside a living cell.

Cell-Penetrating Peptides—Mechanisms of Cellular Uptake and Generation of Delivery Systems

Pharmaceuticals, 2010
The successful clinical application of nucleic acid-based therapeutic strategies has been limited by the poor delivery efficiency achieved by existing vectors. The development of alternative delivery systems for improved biological activity is, therefore,

Synthetic molecular evolution of hybrid cell penetrating peptides

Nature Communications, 2018
Therapeutic peptide nucleic acids can be delivered into cells by conjugation to cell penetrating peptides (CPPs), but efficiency is usually low. Here the authors use synthetic molecular evolution and a luciferase-based library screen to generate new CPPs

Chiral Peptide Nucleic Acids with a Substituent in the N-(2-Aminoethy)glycine Backbone

Molecules, 2012
A peptide nucleic acid (PNA) is a synthetic nucleic acid mimic in which the sugar-phosphate backbone is replaced by a peptide backbone. PNAs hybridize to complementary DNA and RNA with higher affinity and superior sequence selectivity compared to DNA ...
