| TITLE: | Research progress on the mechanisms of Tibetan medicine Gentianopsis paludosa and its chemical components against ulcerative colitis and associated fibrosis |
| 摘要: | 溃疡性结肠炎(UC)是一种慢性、复发性的肠道炎症性疾病,肠纤维化是其严重的并发症和潜在的恶变危险因素。湿生扁蕾是藏医治疗湿热泻痢等胃肠疾病的常用药物之一,其化学成分复杂,包括呫吨酮类、黄酮类、萜类及其他活性组分,具有清热利湿、解毒等功效。本文综述了湿生扁蕾在抗UC及相关纤维化方面的药效物质基础与作用机制研究进展,发现其提取物(如水提取物、乙酸乙酯提取物)及活性成分(如1-羟基-3,7,8-三甲氧基呫吨酮、熊果酸、獐牙菜苦苷、木犀草素)可能通过调控核因子κB、B细胞淋巴瘤-2/B细胞淋巴瘤-2相关X蛋白、转化生长因子β1/Smad等相关信号通路,从抑制炎症因子、抗氧化应激、抑制细胞凋亡、调节肠道菌群及其代谢产物、保护肠道黏膜屏障、调节免疫、抑制上皮-间质转化7个方面,发挥抗UC及相关纤维化的作用。 |
| ABSTRACT: | Ulcerative colitis (UC) is a chronic and relapsing inflammatory disease of the intestine. Intestinal fibrosis represents a severe co mplication and a potential risk factor for malignant transformation. Gentianopsis paludosa is one of the traditional Tibetan medicines commonly used for treating gastrointestinal disorders such as damp-heat diarrhea and dysentery. Its chemical composition is complex, encompassing xanthones, flavonoids, terpenoids, and other bioactive components, and it exhibits properties such as clearing heat, eliminating dampness, and detoxifying. This article reviews the research progress on the pharmacodynamic material basis and mechanisms of G. paludosa against UC and associated fibrosis. Findings suggest that its extracts (e.g., aqueous extract, ethyl acetate extract) and active constituents (e.g., 1-hydroxy-3,7,8-trimethoxyxanthone, ursolic acid, swertiamarin, luteolin) may inhibit inflammatory cytokines, combat oxidative stress, suppress cell apoptosis, regulate intestinal microbiota and their metabolites, protect the intestinal mucosal barrier, modulate immune responses, and inhibit epithelial-mesenchymal transition, through modulating relevant signaling pathways, such as nuclear factor-kappa B, B-cell lymphoma-2 (Bcl-2)/Bcl-2-associated X protein, and transforming growth factor-β 1 /Smad, thus exerting therapeutic effects against UC and its related fibrosis via these seven aspects. |
