Synthesis and characterization of a novel ester-based nucleoamino acid for the assembly of aromatic nucleopeptides for biomedical applications
摘要:
In this work, we report a technological approach to a novel Fmoc-protected nucleoamino acid, based on L-tyrosine, carrying the DNA nucleobase on the hydroxyl group by means of an ester bond, suitable for the solid-phase synthesis of novel aromatic nucleopeptides of potential interest in biomedicine. After ESI-MS and NMR characterization this building block was used for the assembly of a thymine-functionalized tetrapeptide, composed of nucleobase-containing and underivatized L-tyrosine moieties alternated in the backbone.
