Synthesis of oligonucleotide-peptide conjugates carrying the c-myc peptide epitope as recognition system

Oligonucleotide-peptide conjugates 1-3 were prepared by sequential addition of the appropriate Boc-protected amino acids, followed by nucleoside phosphoramidites in the same support. These molecules are designed to be used for triplex formation and for the directed assembly of nanomaterials. The structures of the desired oligonucleotide-peptide conjugates were confirmed by mass spectrometry on small oligonucleotide-peptide conjugates, by gel electrophoresis, and by hybridization with complementary oligonucleotides. Oligonucleotides carrying the c-myc peptide were specifically recognized by the anti-c-myc monoclonal antibody.
