New dsDNA binding unnatural oligopeptides with pyrimidine selectivity

Design and synthesis of intrinsically cell-penetrating nucleopeptides

Nucleopeptides, which are constituted of alpha-amino acids bearing nucleobases at their side chains, are able to penetrate into cells and to reach the nucleus without cytotoxic effects.

EDOTn and MIM, new peptide backbone protecting groups

In recent years, backbone protection has allowed the synthesis of complex peptidic sequences of high interest by preventing chain aggregation and aspartimides formation. Nevertheless, the backbone protectors currently used have some drawbacks: they are difficult to remove and show high steric hindrance. The new backbone protectors presented in this study (EDOTn and MIM) represent an improvement in both aspects.
