title: Synthesis of a novel Fmoc-protected nucleoaminoacid for the solid phase assembly of 4-piperidyl glycine/L-arginine-containing nucleopeptides and preliminary RNA: interaction studies.
abstract: In this work, we report the synthesis of a novel Fmoc-protected nucleoaminoacid, based on 4-piperidinyl glycine, carrying the DNA nucleobase on the secondary amino group, suitable for the solid-phase synthesis of nucleopeptides. After ESI-MS and NMR characterization this building block was used for the assembly of a thymine-functionalized tetrapeptide, composed of 4-piperidinyl glycine and L-arginine moieties alternated in the backbone. The ability to interact with RNA and the efficiency in interfering with the reverse transcription of eukaryotic mRNA of the novel nucleo-tetrapeptide found in this study are in favour of the employment of chiral nucleopeptides based on alternate 4-piperidinyl glycine/L-arginine backbone in biomedicine.
