Use of C5-Diamino-Substituted-Pyridine in Triple Helix Forming Oligonucleotides
摘要:
Triple helical structures can be observed between double-stranded nucleic acids and a third strand through the formation of Hoogsteen hydrogen bonds. We report here the synthesis and the preliminary evaluation of oligonucleotides incorporating 5[N-2-aminoethyl)-3 -aminopropynyl]-2'-deoxyuridine (1) under bar as well as its reduced analogue (2) under bar. Synthesis of two phosphoramidites (8) under bar and (9) under bar and the first melting temperature measurements are described.

Peptide nucleic acids (PNAs) are functional analogues of natural oligonucleotides. Herein, we report the synthesis of PNAs bearing a triazole in lieu of the amide bond assembled using a “click” cycloaddition, their hybridization properties as well as the DNA-templated coupling of the azide and alkyne PNA fragments.
