Outline of Final Research Achievements

We have developed the new glyco-compound to inhibit biosynthesis of cancer-related fucosylation. This compound suppressed invasiveness in the liver cancer cell lines. We also revealed molecular structure of GnT-V which is the glycosyltransferase to enhance cancer metastasis. This proved the unique character for GnT-V. For Alzheimer’s disease, we have identified GnT-III as the glycosyltransferase related to disease state, and performed screening study to discover compounds to inhibit GnT-III. In COPD study, we have produced more effective keratan sulfate disaccharide L4 polymer by chemosynthesis. This L4 polymer suppressed inflammatory response of immune cells by the stronger binding to C-type lectins.

Academic Significance and Societal Importance of the Research Achievements

本研究にて開発された新規糖化合物は、肝がん細胞の浸潤能を抑制するため、新規がん治療薬の候補として期待される。また糖鎖合成酵素GnT-Vの酵素機能の特異性を明らかにしたことにより、がんの転移におけるGnT-Vのより詳細な機能の解明が期待される。また糖鎖合成酵素GnT-IIIがアルツハイマー病に関連することを明らかにしたことは、その病態を理解する上で学術的意義が高い。また、ケラタン硫酸二糖L4の抗炎症性作用を明らかにしたことにより、COPDを含め、炎症性疾患の治療薬としての応用が期待される。
