Synthesis and characterization of cationic PNA bearing 5-ω-aminopropyl-uracil

5-ω-Aminopropyl-uracil bearing PNA monomers are synthesized for solid phase oligomer synthesis using FMOC protection. Several PNA oligomers with differing amounts of aminopropyluracil modification were prepared. These oligomers were found to associate with complementary DNA oligonucleotides.
