稀有糖的研究进展

Research Progress in Rare Sugars

自然界中含量极少的稀有糖在膳食、保健、医药等领域发挥着重要的生理功能。本文简述了几种常见稀有糖的抗癌、清除自由基、神经保护等生物活性,并主要列举了3种成熟的稀有糖合成策略,包括关环转换合成法、两步合成法、Izumoring合成法。同时,对稀有糖的研究与应用前景加以展望。

Rare sugars are defined as monosaccharides and their derivatives rarely exist in nature.They play an important role in the field of food,health and medicine.In this paper,bioactivities such as anticancer,scavenging free radical and neuroprotective function of several rare sugars are described.Meanwhile,three major synthesis strategies such as ring-closing metathesis,twostep synthesis and Izumoring synthesis,for rare sugars were also introduced.In addition,current research and application perspectives of rare sugars were also proposed.
