摘要: 多糖药物是一类安全有效的天然药物,具有抗肿瘤、免疫调节、抗氧化等广泛的药理活性,目前受到越来越多的关注。然而,由于多糖本身的相对分子质量大,大部分没有紫外吸收和荧光基团,使得多糖的定性和定量分析均比较困难。此外,内源性的糖类物质也可能对生物样品中的多糖测定造成一定干扰,因此,多糖药物的体内代谢及PK/PD关键技术一直是研究热点。本文综合近年来发表的相关文献,对多糖药物的生物学活性、药代动力学特征进行综述,提出肠道菌可能是影响多糖药物代谢及药效的潜在“器官”,并对肠道菌介导的多糖药物体内代谢及PK/PD关键技术研究提出思考,以期为多糖药物的药代、药效及分子机制的研究提供更多可参考的科学思路。

Abstract: Polysaccharide drugs are a type of safe and effective natural drug with a wide range of pharmacological activity such as anti-tumor, immunomodulation, and oxidation, and polysaccharide drugs are currently more concerned. However, since the molecular weight of the polysaccharide is quite large, most of which do not have ultraviolet absorption and fluorescent groups, which makes the qualitative and quantitative analysis of polysaccharides are relatively difficult. In addition, endogenous sugar substances may also cause certain interference to polysaccharide assay in biological samples, and therefore, in vivo metabolism and PK/PD key technologies in polysaccharide drugs have been research hotspots. This paper summarizes the relevant literature published in recent years, reviewing the biological activity and pharmacokinetics of polysaccharide drugs, proposing gut bacteria may be potential "organ" affecting metabolism and efficacy of polysaccharide drugs, and providing thoughts on gut bacteria mediating polysaccharide drugs in vivo and key technology research of PK/PD, in order to provide more scientific ideas for pharmacokinetics, pharmacological research and molecular mechanisms of polysaccharide drugs.

Key words: polysaccharide drugs, biological activity, pharmacokinetic characteristics, PK/PD, gut bacteria
