Outline of Final Research Achievements

(1) In 19F NMR analysis of the structure of human telomeric RNA in living cells and in what manner interacts with proteins and ligand molecules (Nucleic Acids Res. 45, 5501, 2017; Nature Protocols 13, 652, 2018.) (ChemistrySelect, 2, 4170, 2017; JACS. 139, 7533, 2017; Molecules 23, 237, 2018). (2) We have discovered the antiparallel RNA quadruplex structure which was thought not to exist until now (Sci. Rep. 7, 6695, 2017; Chem. Commun. 54, 3944, 2018.). (3) We succeeded in developing multifunctional guanine derivatives for detecting G-quadruplex structure (Analyst 142, 4083, 2017; ACS Omega 2, 8843, 2017). (4) We succeeded in analyzing DNA-RNA hybrid quadruplex structure in the cell and detection of telomere DNA by utilizing the click reaction (Bioorg. Med. Chem. 135, 44191, 2014; J. Nat Sci. 2: e 237, 2016; Sci. Rep. 6, 33217, 2016.).
