Zhu L, Liang J. Network pharmacological prediction of the mechanism of action of Shen-Zhu-Lian-Bai Decoction in the treatment of ulcerative colitis. Sci Rep 2024; 14:14183. [PMID: 38902425 PMCID: PMC11190269 DOI: 10.1038/s41598-024-64683-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2023] [Accepted: 06/12/2024] [Indexed: 06/22/2024] Open
Abstract
The incidence of ulcerative colitis (UC) is on the rise globally. Shen-Zhu-Lian-Bai decoction (SZLBD) can relieve the clinical symptoms of UC. This study aimed to investigate the underlying molecular mechanism of SZLBD in the treatment of UC. The key treatment targets of SZLBD for UC were obtained based on the online database, and combined with the STRING database and Cytoscape 3.7.2 software, PPI network was constructed and visualized. The GEO database was utilized to validate the expression levels of core targets in UC. Metascape database GO functional annotation and KEGG pathway enrichment analysis. Molecular docking technology was used to verify the docking of core compounds with key targets. RT-qPCR and Western Blot were used to detect the expression of key targets in HCoEpiC cells for verification. After screening, 67 targets shared by SZLBD and UC were obtained. It is predicted that IL-6, IL-1B, and AKT1 might be the key targets of SZLBD in the treatment of UC. Quercetin was the main active ingredient. GEO results showed that the expression levels of IL-6, IL-1B and AKT1 were higher in the UC group compared to the control group. GO and KEGG analyses showed that these targets were related to apoptosis and inflammation. The results of molecular docking demonstrated that the AKT1 gene, a key target of quercetin, had the highest affinity of -9.2 kcal/mol. Cell experiments found that quercetin could affect the expression of IL-6, IL-1B, and AKT1. This study preliminarily explored and verified the mechanism of action of SZLBD in the treatment of UC, which provides a theoretical basis for subsequent in vivo mechanism studies.

Peng K, Xia S, Xiao S, Zhang M, Liao J, Yu Q. Kuijie decoction ameliorates ulcerative colitis by affecting intestinal barrier functions, gut microbiota, metabolic pathways and Treg/Th17 balance in mice. JOURNAL OF ETHNOPHARMACOLOGY 2024; 319:117316. [PMID: 37852335 DOI: 10.1016/j.jep.2023.117316] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/13/2023] [Revised: 10/09/2023] [Accepted: 10/11/2023] [Indexed: 10/20/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Currently, the clinical treatment is limited and difficult to achieve satisfactory results for ulcerative colitis (UC). The role of traditional Chinese medicine (TCM) in the treatment of UC is very complex. Kuijie decoction (KJD) as a classic TCM, is widely used in the clinical treatment of UC, but the mechanism of its action is still unclear. AIM OF THE STUDY This study is to investigate the protective effects of KJD on UC and the underlying mechanisms. MATERIALS AND METHODS The experimental model of UC was induced by DSS, and KJD was introduced into the model at the same time. Clinical symptoms, including the body weight, colon length and colon histopathological, were used to measure the severity of colitis. The expression of inflammatory cytokines and tight junction proteins was quantified. The effect of KJD on intestinal flora and intestinal metabolism was determined by 16S rRNA and untargeted metabolomics analysis, respectively. The proportion of Th17 cells and Tregs in the spleen was examined by flow cytometry. RESULTS Mice treated with KJD showed significantly alleviated clinical symptoms and histological damage, such as more body weight gain, lower disease activity index (DAI) score, and longer colon length. The administration of KJD also led to the down-regulation of inflammatory mediators, upregulation of the expression of ZO-1, occludin and decreased claudin-2, as well as altered microbiota composition against DSS challenges (especially an increase of Lachnospiraceae). KJD enhanced the percentage of Treg cells but decreased the proportion of Th17 cells to maintain intestinal homeostasis by improving gut microbiota metabolism. CONCLUSIONS In summary, KJD maintained intestinal epithelial homeostasis by regulating epithelial barrier function, intestinal flora, and restoring Th17/Treg balance. KJD has the potential to be a Chinese medicine treatment for UC.

JOURNAL OF ETHNOPHARMACOLOGY 2024; 319:117211. [PMID: 37739100 DOI: 10.1016/j.jep.2023.117211] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/17/2023] [Revised: 09/05/2023] [Accepted: 09/20/2023] [Indexed: 09/24/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Portulaca oleracea L. (PO), popularly known as purslane, has been documented in ethnopharmacology in various countries and regions. Traditional application records indicated that PO might be used extensively to treat the common cold, dysentery, urinary tract infections, coughing, eye infections, skin problems, gynecological diseases, and pediatric illnesses. AIM OF THE REVIEW This paper includes a systematic review of the traditional usage, phytochemicals, pharmacological activity, and potential uses of PO to provide an overview of the research for further exploitation of PO resources. MATERIALS AND METHODS This article uses "Portulaca oleracea L." and "purslane" as the keywords and collects relevant information on PO from different databases, including PubMed, Web of Science, Springer, Science Direct, ACS, Wiley, CNKI, Baidu Scholar, Google Scholar, and ancient meteria medica. RESULTS PO is a member of the Portulacaceae family and is grown worldwide. Traditional Chinese medicine believes that purslane has the effect of improving eyesight, eliminating evil qi, quenching thirst, purgation, diuresis, hemostasis, regulating qi, promoting hair growth, detoxifying, and avoiding epidemic qi. Recent phytochemical investigations have shown that PO is a rich source of flavonoids, homoisoflavonoids, alkaloids, organic acids, esters, lignans, terpenoids, catecholamines, sterols, and cerebrosides. The purslane extracts or compounds have exhibited numerous biological activities such as anti-inflammatory, immunomodulatory, antimicrobial, antiviral, antioxidant, anticancer, renoprotective, hepatoprotective, gastroprotective, metabolic, muscle relaxant, anti-asthmatic and anti-osteoporosis properties. The significant omega-3 fatty acids, vital amino acids, minerals, and vitamins found in purslane also provide nutritional benefits. Purslane as a food/feed additive in the food industry and animal husbandry has caused concern. Its global wide distribution and tolerance to abiotic stress characteristics make it in the future sustainable development of agriculture a certain position. CONCLUSIONS Based on traditional usage, phytochemicals, and pharmacological activity, PO is a potential medicinal and edible plant with diverse pharmacological effects. Due to purslane's various advantages, it may have vast application potential in the food and pharmaceutical industries and animal husbandry.

Abstract
Portulaca oleracea L. (purslane) is a vegetable that contains a variety of active compounds with nutritional properties and has the potential to treat ulcerative colitis (UC). However, the mechanisms underlying the effects of Portulaca oleracea L. polysaccharide (POP) in alleviating UC remain unclear. In this study, we prepared an aqueous extract of purslane and separated a fraction with molecular weight >10 kDa using membrane separation. This fraction was used to isolate POP. The effect of POP on gut microbiota and colon transcriptome in dextran sulfate sodium-induced UC model mice was evaluated. POP treatment reduced inflammation and oxidative stress imbalance in UC mice. In addition, POP improved the intestinal barrier and regulated intestinal homeostasis. Importantly, POP was found to regulate gut microbiota, maintain the levels of retinol and short-chain fatty acids in the gut, promote the proliferation and differentiation of B cells in the colon, and increase the expression of immunoglobulin A. These results provide novel insights into the role of POP in regulating intestinal homeostasis, which should guide further development of POP as a functional food.

Abstract
Porcine epidemic diarrhea virus (PEDV) belongs to the coronavirus family and the coronavirus genus, causing contact enteric infection in pigs. It is one of the most serious diseases that threatens the pig industry. However, there is currently no specific drug to prevent and treat the disease, indicating that we need to be vigilant about the spread of the disease and the development of anti-PEDV drugs. The dried aerial parts of the plant Portulaca oleracea in the family Portulacaceous, whose decoction can be used to treat acute enteritis, dysentery, diarrhea, and other diseases. This study explored the potential mechanism of water extract of Portulaca oleracea (WEPO) in PEDV-induced pyroptosis in Vero cells. PEDV decreased the viability of Vero cells in a dose- and time-dependent manner, causing cell damage, upregulating the level of intracellular Nlrp3, and inhibiting the level of Gasdermin D (GSDMD) and the activation of Caspase-1. WEPO can inhibit PEDV-induced pyroptosis, reduce the elevation of inflammatory factors caused by infection, and exhibit a dose-dependent effect. Knockdown of Caspase-1 and GSDMD separately can induce the production of the inflammatory factor IL-1β to significantly decrease and increase, respectively. These results suggest that WEPO can inhibit cell pyroptosis caused by PEDV and that the Caspase-1 and GSDMD pathways play an important role in this process.

Aqueous Extract on DSS-Induced Ulcerative Colitis in Mice. Antioxidants (Basel) 2023; 12:1400. [PMID: 37507939 PMCID: PMC10376347 DOI: 10.3390/antiox12071400] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2023] [Revised: 06/29/2023] [Accepted: 07/06/2023] [Indexed: 07/30/2023] Open
Abstract
Purslane, a common wild vegetable, contains active substances with various biological functions. However, its effects have been under-investigated in ulcerative colitis (UC). Therefore, this study investigated the therapeutic effects of purslane macromolecular (POEM) and small molecular extracts (POES) on dextran sulfate sodium (DSS)-induced UC in mice. Membrane separation was used to obtain extracts of different molecular weights, and their compositional differences were compared using liquid chromatography-mass spectrometry (LC/MS). POEM contained more proteins and polysaccharides, whereas POES contained more organic acids and alkaloids. These differences in composition were directly responsible for the different degrees of remission of the alleviated UC in model mice. POEM may alleviate UC by regulating the antioxidant capacity and the gut microbiota, whereas the major alleviatory effect of POES was primarily related to the regulation of antioxidant capacity. The POEM and POES effects identified in this study provide a theoretical basis for the development of purslane as a functional food.

Abstract
Multiple in vitro and in vivo model investigations have suggested a broad spectrum of potential mechanisms by which plant/macrofungi-derived non-starch polysaccharides may play a role in the treatment of inflammatory bowel disease (IBD). This article reviews the in vivo and in vitro evidence of different plant-derived polysaccharides for IBD therapy. Their underlying mechanisms, particularly the molecular mechanisms associated with protective effects in the treatment and prevention of IDB, have been well summarized, including anti-inflammatory, epithelial barrier repair, and the regulation of intestinal flora. Emerging studies have observed the potent role of probiotics in IBD, particularly its ability to modulate gut microbiota, a well-known key factor for IBD. In summary, plant/macrofungi-derived polysaccharides have the potential to be a promising agent for the adjuvant treatment and prevention of IBD and will contribute to the design of well-designed clinical intervention trials that will ultimately improve the therapy of IBD.

Abstract
Ulcerative colitis (UC) is an inflammatory bowel disease that is persistent and nonspecific. There are several medications available for the treatment of UC. However, conventional UC medications have substantial adverse effects, low clinical effectiveness, and a high recurrence rate. Therefore, it is critical to discover new medicines that are both safe and effective for UC patients. Natural polysaccharides offer a wide range of pharmacological benefits, including anti-inflammatory, anti-virus, anti-tumor, anti-aging, immune enhancement, and gut flora regulation. In the therapy of UC, natural polysaccharides can modulate inflammatory factors, the immune system, and intestinal flora, and preserve the intestinal mucosa. It demonstrates a good curative effect and is of safety to use, thereby being a potential treatment for UC patients. This paper covers the structure, the pharmacological effects on UC, and the mechanisms of natural polysaccharides. Finally, limitations, challenges, and perspectives are discussed. It is hoped that the findings of this publication will inspire more natural polysaccharides research and provide a theoretical foundation for the creation of new UC medications.

Abstract
Scope To investigate the role of endoplasmic reticulum stress (ERS)‐induced autophagy in inflammatory bowel disease (IBD) and the intervention mechanism of Portulaca oleracea L. (POL) extract, a medicinal herb with anti‐inflammatory, antioxidant, immune‐regulating, and antitumor properties, in vitro and in vivo. Methods and Results An IL‐10‐deficient mouse model is used for in vivo experiments; a thapsigargin (Tg)‐stimulated ERS model of human colonic mucosal epithelial cells (HIECs) is used for in vitro experiments. The levels of ERS‐autophagy‐related proteins are examined by immunofluorescence and Western blot. Cellular ultrastructure is assessed with transmission electron microscopy. POL extract promotes a healing effect on colitis by regulating ERS‐autophagy through the protein kinase R‐like endoplasmic reticulum kinase (PERK)‐eukaryotic initiation factor 2α (eIF2α)/Beclin1‐microtubule‐associated protein light chain 3II (LC3II) pathway. Conclusion Overall, the results of this study further confirm the anti‐inflammatory mechanism and protective effect of POL extract and provide a new research avenue for the clinical treatment of IBD.

Abstract
Inflammatory bowel disease (IBD) is a chronic inflammatory disease impairing the gastrointestinal tract, and its incidence and prevalence have been increasing over time worldwide. IBD greatly reduces peoples' quality of life and results in several life-threatening complications, including polyp, toxic colonic dilatation, intestinal perforation, gastrointestinal bleeding, and cancerization. The current therapies for IBD mainly include drugs for noncritical patients and operation for critical patients. However, continuous use of these drugs causes serious side effects and increased drug resistance, and the demand of effective and affordable drugs with minimal side effects for IBD sufferers is urgent. Natural-derived polysaccharides are becoming a research hotspot for their therapeutic effects on IBD. This study focuses on the research progress of various natural polysaccharides from plants, seaweeds, and mushrooms for the treatment of IBD during recent 20 years. Regulation of oxidative stress, inflammatory status, gut microbiota, and immune system and protection of the intestinal epithelial barrier function are the underlying mechanisms for the natural-derived polysaccharides to treat IBD. The excellent efficacy and safety of polysaccharides make them promising candidates for IBD therapy.

New Class of Anti-Inflammatory Therapeutics Based on Gold (III) Complexes in Intestinal Inflammation-Proof of Concept Based on In Vitro and In Vivo Studies. Int J Mol Sci 2021; 22:ijms22063121. [PMID: 33803793 PMCID: PMC8003307 DOI: 10.3390/ijms22063121] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2021] [Revised: 03/13/2021] [Accepted: 03/15/2021] [Indexed: 02/06/2023] Open
Abstract
Inflammatory bowel diseases (IBD) are at the top of the worldwide rankings for gastrointestinal diseases as regards occurrence, yet efficient and side-effect-free treatments are currently unavailable. In the current study, we proposed a new concept for anti-inflammatory treatment based on gold (III) complexes. A new gold (III) complex TGS 121 was designed and screened in the in vitro studies using a mouse macrophage cell line, RAW264.7, and in vivo, in the dextran sulphate sodium (DSS)-induced mouse model of colitis. Physicochemical studies showed that TGS 121 was highly water-soluble; it was stable in water, blood, and lymph, and impervious to sunlight. In lipopolysaccharide (LPS)-stimulated RAW264.7 cells, the complex showed a potent anti-inflammatory profile, as evidenced in neutral red uptake and Griess tests. In the DSS-induced mouse model of colitis, the complex administered in two doses (1.68 μg/kg, intragastrically, and 16.8 μg/kg, intragastrically, once daily) produced a significant (* p < 0.05) anti-inflammatory effect, as shown by macroscopic score. The mechanism of action of TGS 121 was related to the enzymatic and non-enzymatic antioxidant system; moreover, TGS 121 induced changes in the tight junction complexes expression in the intestinal wall. This is the first study proving that gold (III) complexes may have therapeutic potential in the treatment of IBD.
