A novel synthesis of C(2)-modified peptide nucleic acids (PNAs) is proposed, using a submonomeric strategy with minimally protected building blocks, which allowed a reduction in the required synthetic steps. N(3)-unprotected, D-Lys- and D-Arg-based backbones were used to obtain positively charged PNAs with high optical purity, as inferred from chiral GC measurements. “Chiral-box” PNAs targeting the G12D point mutation of the KRAS gene were produced using this method, showing improved sequence selectivity for the mutated- vs wild-type DNA strand with respect to unmodified PNAs.

Peptide nucleic acids (PNAs) hybridize to natural oligonucleotides according to Watson and Crick base-pairing rules. The robustness of PNA oligomers and ease of synthesis have made them an attractive platform to encode small or macromolecules for microarr
Expanding the scope of PNA-encoded libraries: divergent synthesis of libraries targeting cysteine, serine and metallo-proteases as well as tyrosine phosphatases

Seven PNA-encoded combinatorial libraries targeting proteases and phosphatases with covalent reversible and irreversible mechanism-based inhibitors were prepared. The libraries were synthesized using modified PNA monomers, which dramatically increase the water solubility of the libraries in biologically relevant buffers. The libraries were shown to selectively inhibit targeted enzymes.
Substituted N-ethylglycine derivatives for preparing PNA and PNA/DNA hybrids

There are described N-ethylglycine derivatives of the formula I in which PG is a urethane-type or trityl-type amino protective group which is labile to weak acids, X is NH, O or S, Y is CH2, NH or O, and B' are bases customary in nucleotide chemistry, the exocyclic amino or hydroxyl groups of which being protected by suitable, known protective groups, or are base substitute compounds, and their salts with tert-organic bases, as well as a process for their preparation. The N-ethylglycine derivatives of the formula I are used in the preparation of PNA and PNA/DNA hybrids.
