摘要 以脂多糖(LPS)诱导的小鼠巨噬细胞RAW264.7为体外炎症模型,以促炎症细胞因子白介素-1β(IL-1β)、肿瘤坏死因子-α(TNF-α)、白介素-6(IL-6)和炎症介质NO为指标,考察低聚半乳糖(GOS)的体外抗炎活性,并从聚合度的角度探究GOS抗炎活性的构效关系。结果表明,GOS能显著降低促炎症细胞因子(IL-1β,IL-6,TNF-α)和炎症介质NO的分泌,表现出良好的体外抗炎活性。不同聚合度的GOS在调控促炎症细胞因子与炎症介质分泌能力上差异显著,较高聚合度的GOS表现出更强的体外抗炎活性。 Inflammatory mediator(NO)and proinflammatory factors(IL-1β、TNF-αand IL-6)were utilized to evaluate the anti-inflammatory activity of galactooligosaccharide(GOS)in vitro by LPS-induced RAW264.7 macrophages.Moreover,the structure-activity relationship of this bio-activity was also explored from the perspective of the degree of polymerizations.The results showed that GOS could significantly reduce the secretion of inflammatory mediator(NO)and proinflammatory factors(IL-1β、TNF-αand IL-6),implying that GOS had the excellent anti-inflammatory capacity.Besides,the in vitro anti-inflammatory activities of GOS with different degrees of polymerization indicated that there are significant differences in the ability to regulate the secretion of proinflammatory cytokines and inflammatory mediators.In conclusion,GOS with higher degree of polymerization showed stronger anti-inflammatory activity in vitro.
