Because of a set of exceptional chemical, physical, and biological properties, polyamide or peptide nucleic acids (PNAs) hold a distinctive position among various synthetic ligands designed for DNA-targeting purposes. Cationic pyrimidine PNAs (cpyPNAs) represent a special group of PNAs, which effectively form strand invasion triplexes with double-stranded DNA (dsDNA) also known as P-loops. Extraordinary...
Peptide nucleic acids (PNAs) are a family of synthetic polyamide mimics of nucleic acids that offer a variety of applications. Pyrimidine bis-PNAs can be used for rational design of novel interlocked DNA nanostructures, earring labels, representing locked pseudorotaxanes or locked catenanes. These structures are created through DNA ligase-mediated catenation of duplex DNA with a circularized oligonucleotide...
