Nucleobase‐caged peptide nucleic acids: PNA/PNA duplex destabilization and light‐triggered PNA/PNA recognition

open access: yesJournal of Peptide Science, 2013
The 2‐(o‐nitrophenyl)‐propyl (NPP) group is used as caging group to mask the nucleobases adenine and cytosine in N‐(2‐aminoethyl)glycine peptide nucleic acids (aeg‐PNA). The adeninyl and cytosinyl nucleo amino acid building blocks Fmoc‐aNPP‐aeg‐OH and Fmoc‐cNPP‐aeg‐OH were synthesized and incorporated into PNA sequences by Fmoc solid phase synthesis ...
