| Outline of Final Research Achievements |
Fluorinated sulfonates and phosphonates were designed as inhibitors of sialic acid binding viruses. Three milestones were reached to produce target sialic acid analogues: 1) C-2 fluorine introduction into pyranose analogues, 2) introduction of fluorine and hydroxy groups into C-1 and C-2 positions of open-chain analogues, and 3) substitution of the sialic acid anomeric carboxy with a sulfonamide group.

| Academic Significance and Societal Importance of the Research Achievements |
このプロジェクトで開発した化合物群は、将来の感染爆発（パンデミック）に備えた抗ウィルス薬リードとして役立つものです。そして、薬剤耐性を獲得した微生物・ウィルスにも幅広く効果を示す可能性を持っています。さらには、本化合物群の微生物生産システムも構築しました。本手法は、従来、高価値な医薬品製造のために行っていた工業化学的プロセスを代替する持続可能な手段となり得ます。
