Descrição
Resumo:Tumor-specific accumulation of antisense therapeutics: The conjugation of a receptor-binding peptide allows for the first time the selective transport of oligonucleotide analogues into tumor tissue. By using the tert-butyloxycarbonyl (Boc) protecting group stratergy, hybrids of peptide nucleic acids and peptides are accessible that accumulate in tumor tissue at a tenfold higher concentration than the free peptide nucleic acid.
