Outline of Final Research Achievements

In this study, the syntheses of new iminosugars and thiosugars were investigated.　Synthesis of new iminosugar derivatives was investigated by several methods, including cyclization using diphenyl diselenide, multiple metal catalysts, and chiral pooling method. In the study of thiosugar, the synthesis of thiofuranose derivatives from thioepoxide by cyclization via episulfonium ions was also investigated.
Furthermore, the obtained compounds were evaluated for biological activity and the results were published in several papers.

Academic Significance and Societal Importance of the Research Achievements

学術的意義；これまでに開発されていないイミノ糖・チオ糖の新しい合成法を生み出すことが可能となる。さらにそれらの酵素への影響を解明できる。
社会的意義；糖は、エネルギー源となるだけでなく、核酸の構成成分、タンパク質や脂質に含まれる糖鎖として幅広く活用されている。そのため糖の代謝、糖鎖の形成に関与する酵素をコントロールできるイミノ糖・チオ糖を創出することで、これまでに治療薬がない病気の医薬品開発に貢献できる。
