摘要:

生物碱是吴茱萸中一类主要活性成分, 具有抗肿瘤、抗炎、镇痛和抗菌作用。本文报道吴茱萸中六个主要成分吴茱萸碱、吴茱萸次碱、去氢吴茱萸碱、吴茱萸卡品碱、二氢吴茱萸卡品碱和1-甲基-2-十一烷基-4-(1 H)-喹诺酮潜在的抗炎作用。在人结肠腺癌细胞和RAW264.7巨噬细胞共培养体系中, 当以2 μg/mL脂多糖诱导RAW264.7巨噬细胞产生炎症反应时, 吴茱萸碱、吴茱萸次碱和去氢吴茱萸碱明显下调促炎性细胞因子(Il-6, Il-1βTnf-α)和炎性介质, 诸如环氧化酶-2(Cox-2)和诱导型一氧化氮合酶(iNos)的mRNA表达; 与模型组比较, 给药组跨上皮电阻增高, 紧密连接渗透率降低。总之, 受试化合物具有抗炎活性, 此结果为进一步研究吴茱萸的抗炎机制奠定了基础。

Abstract:

Alkaloids are the main active constituents of the nearly ripe fruits of Euodia rutaecarpa (Juss.) Benth., which possesses antitumor, anti-inflammatory, analgesic and antimicrobial activities. In this study, we aimed to assess the potential anti-inflammatory effects of six main components, evodiamine, rutaecarpine, dehydroevodiamine, evocarpine, dihydroevocarpine and 1-methyl-2-undecyl-4-(1H)-quinolone, in the nearly ripe fruits of E. rutaecarpa. In the co-culture system consisting of the human colorectal adenocarcinoma (Caco-2) cells and RAW264.7 macrophages, inflammation was induced in RAW264.7 cells with 2 μg/mL lipopolysaccharide. The results indicated that evodiamine, rutaecarpine, and dehydroevodiamine significantly down-regulated the mRNA expressions of pro-inflammatory cytokines (Il-6, Il-1β and Tnf-α) and inflammatory mediators, such as cyclooxygenase-2 (Cox-2) and inducible nitric oxide synthase (iNos). Besides, the drug administration group showed a higher transepithelial electrical resistance and a lower tight junction permeability compared with the model group. Taken together, the tested compounds possessed anti-inflammatory effects. Our findings laid the foundation for further research on the anti-inflammatory mechanism of the nearly ripe fruits of E. rutaecarpa.
