| Outline of Final Research Achievements |
In this study, human telomeric RNA oligonucleotides incorporating a conformationally restricted nucleoside such as 8,2’-O-cycloguanosine and 5’,8-cycloguanosine were synthesized and evaluated for their structural properties to find out new functions on the G-quadruplex structure. As main results, we found that introductions of the conformationally restricted nucleosides into human telomeric RNA oligonucleotides induced the helicity and topology changes on the G-quadruplex structure. These results would be valuable to analyze the structures and function of the human telomeric RNA.
