(1→3)-β-D-Glucans are well-established natural biological immunomodulators. However, problems inherited with the natural origin of these polysaccharides bring about significant setbacks, including batch-to-batch heterogeneity and significant differences based on the source and isolation techniques. In this study, we tried to overcome these problems by preparation of a quantitatively new set of oligo-(1→3)-β-D-glucan-based synthetic immunomodulators. Some of these non-natural oligosaccharides showed biological activities, such as stimulation of phagocytosis, modulation of gene expression, and anti-cancer activity, which were superior to natural glucans.
(1→3)-β-D-葡聚糖是成熟的天然生物免疫调节剂。然而,这些多糖的天然来源所带来的问题,包括批次间的异质性和基于来源和分离技术的显著差异,给它们的应用带来了重大阻碍。在本研究中,我们尝试通过制备一组全新的寡-(1→3)-β-D-葡聚糖类合成免疫调节剂来克服这些问题。其中一些非天然的寡糖表现出了生物活性,如刺激吞噬作用、调节基因表达和抗癌活性,这些活性优于天然葡聚糖。
