Nanocarrier based on halloysite and fluorescent probe for intracellular delivery of peptide nucleic acids.

open access: yesJournal of Colloid and Interface Science, 2022
The development of systems able to deliver genetic material into a target site is a challenge for modern medicine. Single-stranded peptide nucleic acids have attracted attention as promising therapeutic molecules for diagnostic and gene therapy. However,

Sequence-Specific Recognition of Double-Stranded DNA by Peptide Nucleic Acid Forming Double-Duplex Invasion Complex

open access: yesApplied Sciences, 2022
Peptide nucleic acid (PNA) is an analog of natural nucleic acids, where the sugar-phosphate backbone of DNA is replaced by an electrostatically neutral N-(2-aminoethyl)glycine backbone.

A minimal hybridization chain reaction (HCR) system using peptide nucleic acids

open access: yesChemical Science, 2021
The HCR represents a powerful tool for amplification in DNA-based circuitry and sensing applications, yet requires the use of long DNA sequences to grant hairpin metastability.

Visible Light-Induced Templated Metathesis of Peptide–Nucleic Acid Conjugates with a Diselenide Bridge

open access: yesBiomolecules, 2023
The use of template molecules as chemical scaffolds that significantly influence the course of the reaction has recently been intensively studied. Peptide nucleic acids (PNA) are molecules that mimic natural nucleic acids.

Conformational constraints of cyclopentane peptide nucleic acids facilitate tunable binding to DNA.

open access: yesNucleic Acids Research, 2021
We report a series of synthetic, nucleic acid mimics with highly customizable thermodynamic binding to DNA. Incorporation of helix-promoting cyclopentanes into peptide nucleic acids (PNAs) increases the melting temperatures (Tm) of PNA+DNA duplexes by ...

Peptide Nucleic Acids [PDF]

open access: yes, 2002
A novel class of compounds known as peptide nucleic acids, bind complementary DNA and RNA strands, and generally do so more strongly than the corresponding DNA or RNA strands while exhibiting increased sequence specificity and solubility.

The folding propensity of α/sulfono-γ-AA peptidic foldamers with both left- and right-handedness

open access: yesCommunications Chemistry, 2021
Controlling the helical structure of peptide foldamers requires detailed understanding of the relationship between primary and secondary structure. Here the effect of monomer stoichiometry and configuration on the helical structures of peptide nucleic ...
