Abstract:
We herein describe the synthesis of two new unlocked nucleic acid building blocks containing hypoxanthine and 2,6-diaminopurine as nucleobase moieties and their incorporation into oligonucleotides. The modified oligonucleotides were used to examine the thermodynamic properties of UNA against unmodified oligonucleotides and the resulting thermodynamic data support that the hydrogen bonding face of UNA is Watson-Crick like.
