Abstract

This study investigated the potential anti-inflammatory and analgesic effects of the rutin-chitooligosaccharide (R-COS) complex both in vitro and in vivo. Initially, the cytotoxicity of R-COS was assessed in RAW 264.7 cells using an MTT assay. Subsequently, an inflammatory study was conducted where R-COS demonstrated a significant reduction in various pro-inflammatory factors (nitric oxide [NO], prostaglandin E2, tumor necrosis factor-α, interleukin-6, interleukin-1, inducible nitric oxide synthase [iNOS], and cyclooxygenase [COX-2]) in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells without compromising cell viability. Furthermore, in vivo analysis showcased the protective effect of R-COS on zebrafish embryos exposed to inflammatory stress induced by LPS. R-COS exhibited inhibition against pro-inflammatory factors, specifically COX-2 and iNOS. Notably, R-COS played a modulatory role in calcitonin gene-related peptide and NO levels in zebrafish, reducing the expression of pro-inflammatory factors. Additionally, the study observed analgesic activity in zebrafish treated with R-COS, which mitigated pain-like behavior triggered by acetic acid. Overall, these findings highlight the potential of R-COS, derived from chitosan, as a promising anti-inflammatory agent with broad applications in healthcare and tissue engineering.

芦丁-壳寡糖复合物:体外和体内抗炎和镇痛性能的综合评价。
本研究对芦丁-壳寡糖(R-COS)复合物在体外和体内的潜在抗炎和镇痛作用进行了研究。最初,使用MTT法评估R-COS在RAW 264.7细胞中的细胞毒性。随后,一项炎症研究表明,在脂多糖(LPS)刺激的RAW 264.7细胞中,R-COS显著降低了各种促炎因子(一氧化氮[NO]、前列腺素E2、肿瘤坏死因子-α、白细胞介素-6、白细胞介素-1、诱导型一氧化氮合酶[iNOS]和环氧化酶[COX-2]),而不影响细胞活力。此外,体内分析显示R-COS对LPS诱导炎症应激的斑马鱼胚胎有保护作用。R-COS对促炎因子,特别是COX-2和iNOS具有抑制作用。值得注意的是,R-COS可调节斑马鱼降钙素基因相关肽和NO水平,降低促炎因子的表达。此外,该研究还观察到经R-COS处理的斑马鱼的镇痛活性,减轻了醋酸引发的类疼痛行为。总的来说,这些发现突出了壳聚糖衍生的R-COS作为一种有前途的抗炎剂在医疗保健和组织工程中具有广泛应用的潜力。
