β¦ Synopsis
We synthesized flavin-containing PNA monomer unit 5 from lumiflavin and prepared PNAs containing a flavin moiety (FPNA) by the standard tBoc chemistry. Each PNA oligomer was purified by reversed-phase HPLC and characterized by MALDI-TOF MS and UV spectra. Thermodynamic analyses indicated that the PNA oligomer containing a flavin moiety near the amino terminal considerably stabilized the PNA-DNA hybrids.

Naphthalimide-containing PNA monomer unit 6 was synthesized for the preparation of PNAs containing a naphthalimide chromophore (NPNA). PNA oligomers were purified by reversed-phase HPLC and characterized by MALDI-TOF MS and UV spectra. Thermodynamic analyses revealed that the PNA oligomer containing
## Abstract Peptide nucleic acids (PNAs) are DNA mimics with a neutral peptide backbone instead of the negatively charged sugar phosphates. PNAs exhibit several attractive features such as high chemical and thermal stability, resistance to enzymatic degradation, and stable binding to their RNA or D
