Research Abstract

Hayakawa has developed efficient solid-phase synthesis of DNA and RNA oligomers via the phosphoramidite method using an acid/azole complex as the promoter. He has also invented a novel phosphoramidite method with molecular sieves as a moisture scavenger, allowing the solution-phase preparation of short oligonucleotides by the use of stoichiometric amounts of starting materials and a promoter. These new approaches have allowed highly efficient synthesis of biologically attractive/important substances such as CMP-Neu5Ac, 2-5A core, c(GpGp), DNA-peptide conjugates, and oligodeoxyribonucleotides with S-acetyl-2-thioethyl triester backbone. Makino has studied to elucidate unsolved nucleic acids structures and its relevance to biological functions. He (1) has established complete mechanisms for all the base damage by nitric oxide and their relevance to cancer and cell death, (2) has found varied isomeric structures of i-motif of C-repeat in human telomere and suggested its relationship with cancer and cell death, (3) has elucidated the relationship between the chirality in phosphorothioate antisenses and their target DNA and RNA recognition ability, and (4) has developed the novel method for peptide library for given base sequences. Sekine has found that a serious side reaction associated with oligonucleotide synthesis in the H-phosphonate approach occurs owing to an intramolecular attack of the 5'-terminal hydroxyl group of the growing chain on the closest internucleotidic phosphoryl group. Based on this finding, an improved H-phosphonate approach using active ester intermediates has been developed. The "proton-block method" as a new strategy for the synthesis of DNA fragments without base protection and post-treatment has been also explored. This strategy was utilized for an innovative route to N-acylated DNA fragments which have proved to have sufficient base-pairing ability.
