“…Interest in dipeptide PNAs was motivated in part by the discovery of willardiine, a natural product isolated from the seeds of the rose Acacia willardiana. , Willardiine contains uracil as a substituent on the side chain of alanine (Chart ). While it seemed possible that a peptide with the proper arrangement of nucleobases would be able to recognize a complementary sequence on the nucleic acid, the first molecules synthesized for this purpose failed to bind effectively to complementary DNA, possibly because of the use of racemic monomers. , However, continued efforts involving lengthening of the linker between the backbone and the nucleobase and/or controlling the chirality of the backbone produced peptides that could interact with complementary strands. Somewhat surprisingly, cationic dipeptide PNAs (i.e., PNAs in which the nucleobase-containing amino acids alternate with cationic residues) have been described only recently. Certain dipeptide PNAs were constructed from nucleobase acetic acid units coupled to the side chain of Lys or other primary-amine-containing amino acids, making possible the synthesis of these molecules by coupling of nucleobases to pre-existing peptides.…”
