摘要

α-半乳糖寡糖(α-GOSs)是一种在植物中发现的天然低聚糖,由于其不易消化的性质和多种生物活性而引起了人们的极大兴趣。然而,它们往往以不可分离的混合物存在,特别是长链物质。本研究利用本实验室开发的硼介导糖元传递(BMAD)方法,成功实现了半乳糖链长度不同的α-GOSs 1-6的全合成。此外,我们研究了化学合成的α-GOSs的免疫增强活性和构效关系(SAR)。结果表明,α-GOSs中半乳糖链的长度显著影响其免疫增强性能。具体来说,含有两个半乳糖单位的α-GOS 2被发现能显著促进巨噬细胞吞噬,增加IL-6、TNF-α和IL-1β等细胞因子的产生。提示α-GOS 2可作为功能性食品中的天然免疫调节剂。

Stereoselective Total Synthesis of α-Galacto-Oligosaccharides Using Boron-Mediated Aglycon Delivery and Evaluation of their Immune-Enhancing Activities.

α-Galacto-oligosaccharides (α-GOSs) are natural oligomeric saccharides found in plants that have garnered significant interest due to their indigestible nature and various biological activities. However, they often exist as inseparable mixtures, particularly long-chain substances. This study successfully achieves the total synthesis of α-GOSs 1-6, featuring different lengths of galactose chains, using the boron-mediated aglycon delivery method developed in our laboratory. Additionally, this study investigates the immune-enhancing activity and structure-activity relationships of the chemically synthesized α-GOSs. It reveals that the length of the galactose chain in the α-GOSs significantly influences their immune-enhancing properties. Specifically, α-GOS 2, which contains two galactose units, is found to markedly promote macrophage phagocytosis and increase the production of cytokines such as IL-6, TNF-α, and IL-1β. These results suggest that α-GOS 2 could serve as a natural immunomodulatory agent in functional foods.
