Abstract
Backgrounds Ulcerative colitis (UC) is a form of chronic inflammatory bowel disease, and UC diagnosis rates continue to rise throughout the globe. The research and development of new drugs for the treatment of UC are urgent, and natural compounds are an important source. However, there is a lack of systematic summarization of natural compounds and their mechanisms for the treatment of UC. Methods We reviewed the literature in the databases below from their inception until July 2023: Web of Science, PubMed, China National Knowledge Infrastructure, and Wanfang Data, to obtain information on the relationship between natural compounds and UC. Results The results showed that 279 natural compounds treat UC through four main mechanisms, including regulating gut microbiota and metabolites (Mechanism I), protecting the intestinal mucosal barrier (Mechanism II), regulating intestinal mucosal immune response (Mechanism III), as well as regulating other mechanisms (Mechanism Ⅳ) such as cellular autophagy modulation and ferroptosis inhibition. Of these, Mechanism III is regulated by all natural compounds. The 279 natural compounds, including 62 terpenoids, 57 alkaloids, 52 flavonoids, 26 phenols, 19 phenylpropanoids, 9 steroids, 9 saponins, 8 quinonoids, 6 vitamins, and 31 others, can effectively ameliorate UC. Of these, terpenoids, alkaloids, and flavonoids have the greatest potential for treating UC. It is noteworthy to highlight that a total of 54 natural compounds exhibit their therapeutic effects by modulating Mechanisms I, II, and III. Conclusion This review serves as a comprehensive resource for the pharmaceutical industry, researchers, and clinicians seeking novel therapeutic approaches to combat UC. Harnessing the therapeutic potential of these natural compounds may significantly contribute to the improvement of the quality of life of patients with UC and promotion of disease-modifying therapies in the future.

[PMID: 39172054 PMCID: PMC11340633 DOI: 10.1002/iid3.1372] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2023] [Revised: 07/22/2024] [Accepted: 07/30/2024] [Indexed: 08/23/2024] Open
Abstract
PURPOSE The aim of this study was to explore whether MAF bZIP transcription factor B (MAFB) might alleviate ulcerative colitis (UC) in dextran sulfate sodium (DSS)-induced mice and LPS-induced IEC-6 cells. METHODS UC in vivo and in vitro model was established by using DSS and LPS, respectively. The mice body weight and disease activity index (DAI) score were recorded daily, and colon length was measured. Moreover, the permeability was evaluated utilizing a fluorescein isothiocyanate dextran (FITC-Dextran) probe. Histopathological changes of DSS-induced colitis mice was assessed utilizing H&E staining. Next, qRT-PCR was performed to detect IL-1β, IL-6, TNF-α, and IL-10 level in in vivo and in vitro. Furthermore, the level of MDA, SOD, CAT, and GSH were evaluated in colon tissues. Besides, the expressions of tight junction proteins and NF-κB pathway relative proteins were examined in colitis mice and IEC-6 cells using western blot, immunohistochemistry and immunofluorescence. RESULTS MAFB level was downregulated in DSS-induced colitis mice. Moreover, the upregulation of MAFB protected mice from DSS-induced colitis by suppressing DSS-induced inflammation, oxidative stress, and intestinal barrier impairment. We also demonstrated that the upregulation of MAFB inactivated NF-κB pathway in DSS-caused colitis mice. Subsequently, we observed that MAFB upregulation could inhibit LPS-caused epithelial barrier impairment and inflammation in IEC-6 cells. Additionally, MAFB overexpression could suppress the activation of NF-κB pathway in IEC-6 cells. CONCLUSION The upregulation of MAFB could protect against UC via the suppression of inflammation and the intestinal barrier impairment through inhibiting the NF-κB pathway.

Anthrahydroquinone‑2,6‑disulfonate attenuates PQ‑induced acute lung injury through decreasing pulmonary microvascular permeability via inhibition of the PI3K/AKT/eNOS pathway. Int J Mol Med 2024; 54:63. [PMID: 38874017 PMCID: PMC11188976 DOI: 10.3892/ijmm.2024.5387] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2024] [Accepted: 05/24/2024] [Indexed: 06/15/2024] Open
Abstract
In paraquat (PQ)‑induced acute lung injury (ALI)/ acute respiratory distress syndrome, PQ disrupts endothelial cell function and vascular integrity, which leads to increased pulmonary leakage. Anthrahydroquinone‑2,6‑disulfonate (AH2QDS) is a reducing agent that attenuates the extent of renal injury and improves survival in PQ‑intoxicated Sprague‑Dawley (SD) rats. The present study aimed to explore the beneficial role of AH2QDS in PQ‑induced ALI and its related mechanisms. A PQ‑intoxicated ALI model was established using PQ gavage in SD rats. Human pulmonary microvascular endothelial cells (HPMECs) were challenged with PQ. Superoxide dismutase, malondialdehyde, reactive oxygen species and nitric oxide (NO) fluorescence were examined to detect the level of oxidative stress in HPMECs. The levels of TNF‑α, IL‑1β and IL‑6 were assessed using an ELISA. Transwell and Cell Counting Kit‑8 assays were performed to detect the migration and proliferation of the cells. The pathological changes in lung tissues and blood vessels were examined by haematoxylin and eosin staining. Evans blue staining was used to detect pulmonary microvascular permeability. Western blotting was performed to detect target protein levels. Immunofluorescence and immunohistochemical staining were used to detect the expression levels of target proteins in HPMECs and lung tissues. AH2QDS inhibited inflammatory responses in lung tissues and HPMECs, and promoted the proliferation and migration of HPMECs. In addition, AH2QDS reduced pulmonary microvascular permeability by upregulating the levels of vascular endothelial‑cadherin, zonula occludens‑1 and CD31, thereby attenuating pathological changes in the lungs in rats. Finally, these effects may be related to the suppression of the phosphatidylinositol‑3‑kinase (PI3K)/protein kinase B (AKT)/endothelial‑type NO synthase (eNOS) signalling pathway in endothelial cells. In conclusion, AH2QDS ameliorated PQ‑induced ALI by improving alveolar endothelial barrier disruption via modulation of the PI3K/AKT/eNOS signalling pathway, which may be an effective candidate for the treatment of PQ‑induced ALI.

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.

Int Immunopharmacol 2024; 133:112110. [PMID: 38652960 DOI: 10.1016/j.intimp.2024.112110] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2023] [Revised: 03/28/2024] [Accepted: 04/16/2024] [Indexed: 04/25/2024]
Abstract
Growing evidence suggests that phosphoinositide 3-kinase (PI3K) and adenosine monophosphate-activated protein kinase (AMPK) signaling cascades are critical in ulcerative colitis (UC) pathophysiology by influencing gut mucosal inflammation. Recently, the coloprotective properties of dipeptidyl peptidase-IV (DPP-IV) inhibitors have emerged. Thus, this study assessed for the first time the potential mitigating impact of a DPP-IV inhibitor, vildagliptin (Vilda), on oxazolone (OXZ)-induced colitis in rats, targeting the role of PI3K/AKT/mTOR and AMPK/Nrf2 pathways. Thirty-two adult Albino rats were divided into four groups: control, Vilda (10 mg/kg/day orally), OXZ (300 µL of 5 % OXZ in 50 % aqueous ethanol solution introduced once into the colon via catheter), and Vilda+OXZ. Inflammatory cytokines (interleukin 13, tumor necrosis factor-α, interleukin 10), oxidative/endoplasmic reticulum stress markers (myeloperoxidase, reduced glutathione, catalase, CHOP), mitochondrial reactive oxygen species, adenosine triphosphate levels, and mitochondrial transmembrane potential were estimated. p-AMPK, p-AKT, beclin-1, and SQSTM1 levels were immunoassayed. Nrf2, PI3K, and mTOR expression levels were quantified using the real-time polymerase chain reaction. Furthermore, p-NF-ĸBp65 and LC3II immunoreactivity were evaluated. Vilda administration effectively ameliorated OXZ-induced colitis, as evidenced by the reduced Disease Activity Index, macroscopic colon damage score, colon weight/length ratio, ulcer index, and histopathological and electron microscopic changes in the colon tissues. Vilda treatment also counteracted OXZ-triggered inflammation, oxidative/endoplasmic reticulum stress, mitochondrial dysfunction, and enhanced autophagy in the colon. Vilda substantially suppressed PI3K/AKT/mTOR and activated the AMPK/Nrf2 pathway. Vilda has potent coloprotective and anti-ulcerogenic properties, primarily attributed to its antiinflammatory, antioxidant, and modulatory impact on mitochondrial dysfunction and autophagy activity. These effects were mostly mediated by suppressing PI3K/AKT/mTOR and activating AMPK/Nrf2 signaling cascades, suggesting a potential role of Vilda in UC therapy.

Abstract
Artemisinin, a traditional Chinese medicine with remarkable antimalarial activity. In recent years, studies demonstrated that artemisinin and its derivatives (ARTs) showed anti-inflammatory and immunoregulatory effects. ARTs have been developed and gradually applied to treat autoimmune and inflammatory diseases. However, their role in the treament of patients with autoimmune and inflammatory diseases in particular is less well recognized. This review will briefly describe the history of ARTs use in patients with autoimmune and inflammatory diseases, the theorized mechanisms of action of the agents ARTs, their efficacy in patients with autoinmmune and inflammatory diseases. Overall, ARTs have numerous beneficial effects in patients with autoimmune and inflammatory diseases, and have a good safety profile.

Abstract
Paeoniflorin (PF) is the primary component derived from Paeonia lactiflora and white peony root and has been used widely for the treatment of ulcerative colitis (UC) in China. UC primarily manifests as a chronic inflammatory response in the intestine. In the present study, a network pharmacology approach was used to explore the specific effects and underlying mechanisms of action of PF in the treatment of UC. A research strategy based on network pharmacology, combining target prediction, network construction, Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis, and molecular docking simulation was used to predict the targets of PF. A total of 288 potential targets of PF and 599 UC-related targets were identified. A total of 60 therapeutic targets of PF against UC were identified. Of these, 20 core targets were obtained by protein-protein interaction network construction. GO and KEGG pathway analyses showed that PF alleviated UC through EGFR tyrosine kinase inhibitor resistance, the IL-17 signaling pathway, and the PI3K/AKT signaling pathway. Molecular docking simulation showed that AKT1 and EGFR had good binding energy with PF. Animal-based experiments revealed that the administration of PF ameliorated the colonic pathological damage in a dextran sulfate sodium-induced mouse model, resulting in lower levels of proinflammatory cytokines including IL-1β, IL-6, and TNF-α, and higher levels of IL-10 and TGF-β. PF decreased the mRNA and protein expression levels of AKT1, EGFR, mTOR, and PI3K. These findings suggested that PF plays a therapeutic protective role in the treatment of UC by regulating the PI3K/AKT signaling pathway.

Abstract
Inflammatory Bowel Disease (IBD) is a chronic and relapsing inflammatory condition characterized by severe symptoms such as diarrhea, fatigue, and weight loss. Growing evidence underscores the direct involvement of the nuclear factor-erythroid 2-related factor 2 (NRF2) in the development and progression of IBD, along with its associated complications, including colorectal cancer. The NRF2 pathway plays a crucial role in cellular responses to oxidative stress, and dysregulation of this pathway has been implicated in IBD. Flavones, a significant subclass of flavonoids, have shown pharmacological impacts in various diseases including IBD, through the NRF2 signaling pathway. In this study, we conducted a screening of compounds with a flavone structure and identified NJK15003 as a promising NRF2 activator. NJK15003 demonstrated potent NRF2 activation, as evidenced by the upregulation of downstream proteins, promoter activation, and NRF2 nuclear translocation in IBD cellular models. Treatment with NJK15003 effectively restored the protein levels of tight junctions in cells treated with dextran sodium sulfate (DSS) and in DSS-treated mice, suggesting its potential to protect cells from barrier integrity disruption in IBD. In DSS-treated mice, the administration of NJK15003 resulted in the prevention of body weight loss, a reduction in colon length shortening, and a decrease in the disease activity index. Furthermore, NJK15003 treatment substantially alleviated inflammatory responses and apoptotic cell death in the colon of DSS-treated mice. Taken together, this study proposes the potential utility of NRF2-activating flavone compounds, exemplified by NJK15003, for the treatment of IBD.

Gao X, Lin X, Wang Q, Chen J. Artemisinins: Promising drug candidates for the treatment of autoimmune diseases. Med Res Rev 2024; 44:867-891. [PMID: 38054758 DOI: 10.1002/med.22001] [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: 09/21/2023] [Revised: 11/02/2023] [Accepted: 11/22/2023] [Indexed: 12/07/2023]
Abstract
Autoimmune diseases are characterized by the immune system's attack on one's own tissues which are highly diverse and diseases differ in severity, causing damage in virtually all human systems including connective tissue (e.g., rheumatoid arthritis), neurological system (e.g., multiple sclerosis) and digestive system (e.g., inflammatory bowel disease). Historically, treatments normally include pain-killing medication, anti-inflammatory drugs, corticosteroids, and immunosuppressant drugs. However, given the above characteristics, treatment of autoimmune diseases has always been a challenge. Artemisinin is a natural sesquiterpene lactone initially extracted and separated from Chinese medicine Artemisia annua L., which has a long history of curing malaria. Artemisinin's derivatives such as artesunate, dihydroartemisinin, artemether, artemisitene, and so forth, are a family of artemisinins with antimalarial activity. Over the past decades, accumulating evidence have indicated the promising therapeutic potential of artemisinins in autoimmune diseases. Herein, we systematically summarized the research regarding the immunoregulatory properties of artemisinins including artemisinin and its derivatives, discussing their potential therapeutic viability toward major autoimmune diseases and the underlying mechanisms. This review will provide new directions for basic research and clinical translational medicine of artemisinins.

Abstract
Dihydroartemisinin (DHA), a derivative of artemisinin which is primarily used to treat malaria in clinic, also confers protective effect on lipopolysaccharide-induced nephrotoxicity. While, the activities of DHA in cisplatin (CDDP)-caused nephrotoxicity are elusive. To investigate the role and underlying mechanism of DHA in CDDP-induced nephrotoxicity. Mice were randomly separated into four groups: normal, CDDP, and DHA (25 and 50 mg/kg were orally injected 1 h before CDDP for consecutive 10 days). All mice except the normal were single injected intraperitoneally with CDDP (22 mg/kg) for once on the 7th day. Combined with quantitative proteomics and bioinformatics analysis, the impact of DHA on renal cell apoptosis, oxidative stress, biochemical indexes, and inflammation in mice were investigated. Moreover, a human hepatocellular carcinoma cells xenograft model was established to elucidate the impact of DHA on tumor-related effects of CDDP. DHA reduced the levels of creatinine (CREA) (p < 0.01) and blood urea nitrogen (BUN) (p < 0.01), reversed CDDP-induced oxidative, inflammatory, and apoptosis indexes (p < 0.01). Mechanistically, DHA attenuated CDDP-induced inflammation by inhibiting nuclear factor κB p65 (NFκB p65) expression, and suppressed CDDP-induced renal cell apoptosis by inhibiting p63-mediated endogenous and exogenous apoptosis pathways. Additionally, DHA alone significantly decreased the tumor weight and did not destroy the antitumor effect of CDDP, and did not impact AST and ALT. In conclusion, DHA prevents CDDP-triggered nephrotoxicity via reducing inflammation, oxidative stress, and apoptosis. The mechanisms refer to inhibiting NFκB p65-regulated inflammation and alleviating p63-mediated mitochondrial endogenous and Fas death receptor exogenous apoptosis pathway.

Ameliorative effects of androstenediol against acetic acid-induced colitis in male wistar rats via inhibiting TLR4-mediated PI3K/Akt and NF-κB pathways through estrogen receptor β activation. Int Immunopharmacol 2024; 127:111414. [PMID: 38141404 DOI: 10.1016/j.intimp.2023.111414] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2023] [Revised: 12/13/2023] [Accepted: 12/16/2023] [Indexed: 12/25/2023]
Abstract
5-androstenediol (ADIOL) functions as a selective estrogen receptor β (ERβ) ligand with a protective effect against many diseases. So, we conducted a novel insight into its role in acetic acid (AA)-induced colitis and investigated its effect on TLR4-Mediated PI3K/Akt and NF-κB Pathways and the potential role of ERβ as contributing mechanisms. METHODS Rats were randomized into 5 Groups; Control, Colitis, Colitis + mesalazine (MLZ), Colitis + ADIOL, and Colitis + ADIOL + PHTPP (ER-β antagonist). The colitis was induced through a rectal enema of acetic acid (AA) on the 8th day. At the end of treatment, colons were collected for macroscopic assessment. Tissue levels of malondialdehyde (MDA), superoxide dismutase (SOD), nuclear factor kappa b (NF-κB), toll-like receptor (TLR4), and phosphorylated Protein kinase B (pAKT) were measured. Besides, Gene expression of interleukin-1beta (IL-1β), metalloproteases 9 (Mmp9), inositol 3 phosphate kinase (PI3K), Neutrophil gelatinase-associated lipocalin (NGAL), ERβ and NLRP6 were assessed. Histopathological and immunohistochemical studies were also investigated. RESULTS Compared to the untreated AA group, the disease activity index (DAI) and macroscopic assessment indicators significantly decreased with ADIOL injections. Indeed, ADIOL significantly decreased colonic tissue levels of MDA, TLR4, pAKT, and NF-κB immunostainig while increased SOD activity and β catenin immunostainig. ADIOL mitigated the high genetic expressions of IL1β, NGAL, MMP9, and PI3K while increased ERβ and NLRP6 gene expression. Also, the pathological changes detected in AA groups were markedly ameliorated with ADIOL. The specific ERβ antagonist, PHTPP, largely diminished these protective effects of ADIOL. CONCLUSION ADIOL could be beneficial against AA-induced colitis mostly through activating ERβ.

Abstract
This study was sought to investigate the chemical composition and antibacterial and antiulcerative colitis (UC) effects of essential oil from Pruni Semen (PSEO). A GC-MS assay showed that the major compounds in PSEO were products of amygdalin hydrolysis, which possessed great antibacterial and anti-inflammatory potential. In vitro antibacterial experiments demonstrated that PSEO treatment inhibited activity of four kinds of intestinal pathogens probably by disrupting the cell wall. Further in vivo studies showed that PSEO administration significantly improved physiological indexes, attenuated histopathological characteristics, and inhibited proinflammatory cytokine production in dextran sulfate sodium (DSS)-induced UC mice. Network pharmacology and molecular docking results predicted that PSEO might prevent UC via regulating the PI3K/AKT pathway. Western blotting and immunofluorescence assays were further conducted for verification, and the results evidenced that PSEO intervention significantly regulated the PI3K/AKT pathway and the expression of its downstream proteins in DSS-induced mice. PSEO might provide a new dietary strategy for UC treatment.

Abstract
IMPORTANCE Infectious bronchitis virus (IBV) is an acute and highly infectious viral disease that seriously endangered the development of the chicken industry. However, due to the limited effectiveness of commercial vaccines, there is an urgent need to develop safe and effective anti-IBV drugs. Forsythoside A (FTA) is a natural ingredient with wide pharmacological and biological activities, and it has been shown to have antiviral effects against IBV. However, the antiviral mechanism of FTA is still unclear. In this study, we demonstrated that FTA can inhibit cell apoptosis and autophagy induced by IBV infection by regulating the PI3K/AKT/NF-κB signaling pathway. This finding is important for exploring the role and mechanism of FTA in anti-IBV infection, indicating that FTA can be further studied as an anti-IBV drug.

Abstract
Ulcerative colitis (UC) is one of the most common subtypes of inflammatory bowel disease (IBD) that affects the colon and is characterized by severe intestinal inflammation. Canagliflozin is a widely used antihyperglycemic agent, a sodium-glucose cotransporter-2 (SGLT2) inhibitor that enhances urinary glucose excretion. This study aims to provide insights into the potential benefits of canagliflozin as a treatment for UC by addressing possible cellular signals. Acetic acid (AA; 4% v/v) was administered intrarectally to induce colitis. Canagliflozin is given orally at a dose of 10 mg/kg/day. Canagliflozin attenuates inflammation in AA-induced colitis, evidenced by significant and dose-dependently downregulation of p38 MAPK, NF-κB-p65, IKK, IRF3, and NADPH-oxidase as well as colonic levels of IL-6 and IL-1β and MPO enzymatic activity. Canagliflozin mitigates colonic oxidative stress by decreasing MDA content and restoring SOD enzymatic activities and GSH levels mediated by co-activating of Nrf2, PPARγ, and SIRT1 pathways. Moreover, an in-silico study confirmed that canagliflozin was specific to all target proteins in this study. Canagliflozin's binding affinity with its target proteins indicates and confirms its effectiveness in regulating these pathways. Also, network pharmacology analysis supported that canagliflozin potently attenuates UC via a multi-target and multi-pathway approach.

Abstract
Ulcerative Colitis (UC) is a major type of chronic inflammatory bowel disease of the colonic mucosa and exhibits progressive morbidity. The incidence and prevalence of UC is increasing worldwide. The global burden of UC, which can substantially reduce quality of life, is clearly increasing. These data highlight the need for research into prevention of UC and innovations in health-care systems to manage this complex and costly disease. Glucagon-like peptide-1 (GLP-1), a new antidiabetic drug, is used to treat Type 2 Diabetes Mellitus (T2DM). Accumulating evidence suggests that GLP-1 has additional roles other than glucose-lowering effects. Despite the abundance of GLP-1 research, studies in UC have been less consistent, especially body weight; for example, body weight, colon length, colon injury score, intestinal microbiota, remain to be studied further. To date, the molecular mechanism of the protective effect of GLP-1 on UC remains obscure. The effect of GLP-1 was studied by using a dextran sulfate sodium (DSS)-induced colitic mice and lipopolysaccharide (LPS) treated RAW264.7 cells (macrophage cell line) under in vivo and in vitro conditions, respectively. Our results indicate that GLP-1 significantly relieves ulcerative colitis as it represses the production of proinflammatory mediators. In addition, GLP-1 blocks the activation of the protein kinase B (AKT)/nuclear factor-κB (NF-κB), and mitogen-activated protein kinase (MAPK) signaling pathways. GLP-1 also alleviates DSS-induced injury to the intestinal mucosa and dysbiosis of gut microbiota. Altogether, GLP-1 has protection effect on ulcerative colitis. Thus, GLP-1 can be considered as a potential therapeutic candidate for the treatment of UC.

Abstract
Rebamipide is a quinolone derivative that has been commonly used for the treatment of gastric and duodenal ulcers. However, the molecular mechanisms of rebamipide against acetic acid-evoked colitis have not been adequately examined. Hence, the current study aimed to investigate the ameliorative effect of rebamipide in a rat model of acetic acid-evoked ulcerative colitis and the linked mechanisms pertaining to SIRT1/FoxO3a/Nrf2 and PI3K/AKT pathways. Herein, colitis was induced by the intrarectal administration of 3% acetic acid solution in saline (v/v) while rebamipide was administered by oral gavage (100 mg/kg/day) for seven days before the colonic insult. The colonic injury was examined by macroscopical and microscopical examination. The current findings demonstrated that rebamipide significantly improved the colonic injury by lowering the colonic disease activity index and macroscopic mucosal injury score. Moreover, it mitigated the histopathological aberrations and microscopical damage score. The favorable outcomes of rebamipide were driven by combating inflammation evidenced by dampening the colonic expression of NF-κBp65 and the pro-inflammatory markers CRP, TNF-α, and IL-6. In the same context, rebamipide curtailed the colonic pro-inflammatory PI3K/AKT pathway as seen by downregulating the immunostaining of PI3K and p-AKT(Ser473) signals. In tandem, rebamipide combated the colonic pro-oxidant events and augmented the antioxidant milieu by significantly diminishing the colonic TBARS and replenishing GSH, SOD, GST, GPx, and CAT. In the same regard, rebamipide stimulated the colonic upstream SIRT1/FoxO3a/Nrf2 axis by upregulating the expression of SIRT1, FoxO3a, and Nrf2, alongside downregulating Keap-1 gene expression. These antioxidant actions were accompanied by upregulation of the protein expression of the cytoprotective signal PPAR-γ in the colons of rats. In conclusion, the present findings suggest that the promising ameliorative features of rebamipide against experimental colitis were driven by combating the colonic inflammatory and oxidative responses. In perspective, augmentation of colonic SIRT1/FoxO3a/Nrf2 and inhibition of PI3K/AKT pathways were engaged in the observed favorable outcomes.

Abstract
Artemisinin, an antimalarial traditional Chinese herb, is isolated from Artemisia annua. L, and has shown fewer side effects. Several pieces of evidence have demonstrated that artemisinin and its derivatives exhibited therapeutic effects on diseases like malaria, cancer, immune disorders, and inflammatory diseases. Additionally, the antimalarial drugs demonstrated antioxidant and anti-inflammatory activities, regulating the immune system and autophagy and modulating glycolipid metabolism properties, suggesting an alternative for managing kidney disease. This review assessed the pharmacological activities of artemisinin. It summarized the critical outcomes and probable mechanism of artemisinins in treating kidney diseases, including inflammatory, oxidative stress, autophagy, mitochondrial homeostasis, endoplasmic reticulum stress, glycolipid metabolism, insulin resistance, diabetic nephropathy, lupus nephritis, membranous nephropathy, IgA nephropathy, and acute kidney injury, suggesting the therapeutic potential of artemisinin and its derivatives in managing kidney diseases, especially the podocyte-associated kidney diseases.

Gong S, Lv R, Fan Y, Shi Y, Zhang M. The potential mechanism of Bletilla striata in the treatment of ulcerative colitis determined through network pharmacology, molecular docking, and in vivo experimental verification. NAUNYN-SCHMIEDEBERG'S ARCHIVES OF PHARMACOLOGY 2022; 396:983-1000. [PMID: 36576506 PMCID: PMC9795151 DOI: 10.1007/s00210-022-02370-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 08/14/2022] [Accepted: 12/16/2022] [Indexed: 12/29/2022]
Abstract
Ulcerative colitis (UC) is a chronic nonspecific intestinal inflammatory disease, which belongs to a subtype of inflammatory bowel disease, but still lacks effective drug treatment. Bletilla striata (B. striata) is one of the most valuable traditional Chinese medicines (TCMs) in China, can stop bleeding, can promote wound healing, and can regulate immunity. Based on data mining, B. striata was found to be a common TCM for the treatment of UC, but the exact therapeutic mechanism is not yet known. This study aims to explore the potential mechanisms of B. striata in the treatment of UC using network pharmacology, molecular docking techniques, and in vivo experimental research. We extracted the active ingredients and targets of B. striata from the Traditional Chinese Medicine Systems Pharmacology (TCMSP) database and analysis platform. We retrieved and screened the corresponding UC-related target genes in multiple databases. Subsequently, we constructed an herb-ingredient-target-disease-network, generated a protein-protein interaction network, performed Gene Ontology enrichment analysis, and performed Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis to identify potential treatment mechanisms. After screening for key active ingredients and target genes, we performed molecular docking using AutoDock Vina software to select the best binding target for molecular docking and validate the binding activity. The UC model was established in mice, and the results of network pharmacology and molecular docking were verified by in vivo experiments. In all, 5 compounds were obtained from the TCMSP database, and 74 UC-related pathogenic genes were obtained from GeneCards, DisGeNET, OMIM, TTD, and DrugBank. After KEGG enrichment analysis, pathways in cancer, the phosphatidylinositol 3-kinase (PI3K)/AKT signalling pathway, and metabolic pathways were identified as the top three signalling pathways associated with UC treatment. The results of molecular docking showed that the active components of B. striata have good binding activities to the pivotal targets epidermal growth factor receptor (EGFR) and PIK3CA. In a dextran sulphate sodium-induced colitis model, we found that B. striata can alleviate the symptoms of UC, decrease the secretion of the inflammatory cytokines interleukin-6 and tumour necrosis factor-α, and downregulate the expression levels of EGFR, PIK3CA, and p-AKT. In conclusion, the treatment of UC with B. striata may alleviate the inflammatory response of the colon, and B. striata mainly inhibits the EGFR/PI3K/AKT signalling pathways.

Abstract
Quercetin, a flavonoid that is present in vegetables and fruits, has been found to have anti-inflammatory effects. However, the mechanism by which it inhibits colitis is uncertain. This study aimed to explore the effect and pharmacological mechanism of quercetin on dextran sodium sulfate (DSS)-induced ulcerative colitis (UC). Mice were given a 4% (w/v) DSS solution to drink for 7 days, followed by regular water for the following 5 days. Pharmacological mechanisms were predicted by network pharmacology. High-throughput 16S rDNA sequencing was performed to detect changes in the intestinal microbiota composition. Enzyme-linked immunosorbent assay and western blotting were performed to examine the anti-inflammatory role of quercetin in the colon. Quercetin attenuated DSS-induced body weight loss, colon length shortening, and pathological damage to the colon. Quercetin administration modulated the composition of the intestinal microbiota in DSS-induced mice and inhibited the growth of harmful bacteria. Network pharmacology revealed that quercetin target genes were enriched in inflammatory and neoplastic processes. Quercetin dramatically inhibited the expression of phosphorylated protein kinase B (AKT) and phosphatidylinositol 3-kinase (PI3K). Quercetin has a role in the treatment of UC, with pharmacological mechanisms that involve regulation of the intestinal microbiota, re-establishment of healthy microbiomes that favor mucosal healing, and the inhibition of PI3K/AKT signaling.

Integrated systematic pharmacology analysis and experimental validation to reveal the mechanism of action of Semen aesculi on inflammatory bowel diseases. JOURNAL OF ETHNOPHARMACOLOGY 2022; 298:115627. [PMID: 35985613 DOI: 10.1016/j.jep.2022.115627] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/06/2022] [Revised: 07/02/2022] [Accepted: 08/06/2022] [Indexed: 06/15/2023]
Abstract
BACKGROUND AND ETHNOPHARMACOLOGICAL RELEVANCE Semen aesculi (SA), a traditional Chinese herb, has been used in the treatment of gastrointestinal disease for thousands of years. The escin was the main components of SA. A growing number of research showed that escin has a wide range of pharmacological activities in intestinal barrier dysfunction. AIM OF THE STUDY Inflammatory bowel diseases (IBD) are an idiopathic disease of the intestinal tract with the hallmark features of mucosal inflammation and loss of barrier function. The theory of traditional Chinese medicine (TCM) suggests that SA plays a potential role in protecting the gastrointestinal diseases. The present study aimed to explore the effects of SA on the intestinal barrier under existing inflammatory conditions and elucidate underlying mechanisms. MATERIALS AND METHODS The bioactive components of SA and their predicted biological targets were combined to develop a compound target pathway network. It is used to predict the bioactive components, molecular targets, and molecular pathways of SA in improving IBD. The ingredients of SA were extracted by decoction either in water and ethanol and separated into four fractions (AE, EE, PEE and PCE). The effects of extractions were evaluated in the lipopolysaccharide (LPS)-induced RAW264.7 macrophages cell model, LPS-induced intestinal barrier injury model and imodium-induced constipation model. The high-performance liquid chromatography (HPLC) analysis was performed to identify the bioactive components. RESULTS The compound-target pathway network was identified with 10 bioactive compounds, 166 IBD-related targets, and 52 IBD-related pathways. In LPS-induced RAW264.7 cells, PEE and PCE significantly decreased nitric oxide (NO) production and TNF-α level. In mice, PEE and PCE administration improved intestinal barrier damage, increased intestinal motility, reduced levels of TNF-α and diamine oxidase (DAO). Furthermore, PEE and PCE administration not only decreased expression of p-Akt, p-IκBα, nuclear p-p65, and TNF-α level, but also increased expression of the zonula occludin-1 (ZO-1) in LPS-induced intestinal barrier injury model. The escin content of AE, EE, PEE and PCE gradually increased with an increase of the bioactivity. CONCLUSIONS Escin was the main bioactive components of SA. The effects of SA on IBD were mediated by repairing the intestinal barrier and promoting intestinal motility. The mechanism of action of SA is related to inhibiting the Akt/NF-κB signaling pathway in intestinal tissue, at least, in part. Our results provide a scientific basis for further exploring the mechanisms involved in the beneficial effects of SA in IBD.

Dihydroartemisinin Attenuated Intervertebral Disc Degeneration via Inhibiting PI3K/AKT and NF-κB Signaling Pathways. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2022; 2022:8672969. [PMID: 36120596 PMCID: PMC9481359 DOI: 10.1155/2022/8672969] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/22/2022] [Accepted: 08/13/2022] [Indexed: 11/24/2022]
Abstract
Intervertebral disc degeneration (IDD) is the leading cause of low back pain (LBP). However, effective therapeutic drugs for IDD remain to be further explored. Inflammatory cytokines play a pivotal role in the onset and progression of IDD. Dihydroartemisinin (DHA) has been well reported to have powerful anti-inflammatory effects, but whether DHA could ameliorate the development of IDD remained unclear. In this study, the effects of DHA on extracellular matrix (ECM) metabolism and cellular senescence were firstly investigated in nucleus pulposus cells (NPCs) under tumor necrosis factor alpha (TNFα)-induced inflammation. Meanwhile, AKT agonist sc-79 was used to determine whether DHA exerted its actions through regulating PI3K/AKT and NF-κB signaling pathways. Next, the therapeutic effects of DHA were tested in a puncture-induced rat IDD model. Finally, we detected the activation of PI3K/AKT and NF-κB signaling pathways in clinical degenerative nucleus pulposus specimens. We demonstrated that DHA ameliorated the imbalance between anabolism and catabolism of extracellular matrix and alleviated NPCs senescence induced by TNFα in vitro. Further, we illustrated that DHA mitigated the IDD progression in a puncture-induced rat model. Mechanistically, DHA inhibited the activation of PI3K/AKT and NF-κB signaling pathways induced by TNFα, which was undermined by AKT agonist sc-79. Molecular docking predicted that DHA bound to the PI3K directly. Intriguingly, we also verified the activation of PI3K/AKT and NF-κB signaling pathways in clinical degenerative nucleus pulposus specimens, suggesting that DHA may qualify itself as a promising drug for mitigating IDD.

Abstract
Artesunate is a widely used drug in clinical treatment of malaria. The aim of this study was to investigate the therapeutic mechanism of artesunate on malaria using an integrated strategy of network pharmacology and serum metabolomics. The mice models of malaria were established using 2 × 107 red blood cells infected with Plasmodium berghei ANKA injection. Giemsa and hematoxylin-eosin (HE) staining were used to evaluate the efficacy of artesunate on malaria. Next, network pharmacology analysis was applied to identify target genes. Then, a metabolomics strategy has been developed to find the possible significant serum metabolites and metabolic pathways induced by artesunate. Additionally, two parts of the results were integrated to confirm each other. Giemsa and HE staining results showed that artesunate significantly inhibited the proliferation of Plasmodium and reduced liver and spleen inflammation. Based on metabolomics, 18 differential endogenous metabolites were identified as potential biomarkers related to the artesunate for treating malaria. These metabolites were mainly involved in the relevant pathways of biosynthesis of unsaturated fatty acids; aminoacyl-tRNA biosynthesis; valine, leucine, and isoleucine biosynthesis; and phenylalanine, tyrosine, and tryptophan biosynthesis. The results of the network pharmacology analysis showed 125 potential target genes related to the treatment of malaria with artesunate. The functional enrichment was mainly associated with lipid and atherosclerosis; pathways of prostate cancer and proteoglycans in cancer; and PI3K-Akt, apoptosis, NF-κB, Th17 cell, and AGE-RAGE signaling pathways. These findings were partly consistent with the findings of the metabolism. Our results further suggested that artesunate could correct the inflammatory response caused by malaria through Th17 cell and NF-κB pathways. Meanwhile, our work revealed that cholesterol needed by Plasmodium berghei came directly from serum. Cholesterol and palmitic acid may be essential in the growth and reproduction of Plasmodium berghei. In summary, artesunate may have an effect on anti-malarial properties through multiple targets.

Abstract
Background Artemisinin and its derivatives have potential antidiabetic effects. There is no evaluation of reported studies in the literature on the treatment of diabetic nephropathy (DN), one of the commonest diabetic microangiopathies, with artemisinins. Here, we aimed to evaluate preclinical evidence for the efficacy and possible mechanisms of artemisinins in reducing diabetic renal injury. Methods We conducted an electronic literature search in fourteen databases from their inception to November 2021. All animal studies assessing the efficacy and safety of artemisinins in DN were included, regardless of publication or language. Overall, 178 articles were screened according to predefined inclusion and exclusion criteria. Finally, 18 eligible articles were included in this systematic review. The SYstematic Review Center for Laboratory animal Experimentation (SYRCLE) risk-of-bias tool was used to assess the risk of bias in the included studies. The primary outcomes were kidney function, proteinuria, and renal pathology. Secondary endpoints included changes in fasting plasma glucose (FPG) levels, body weight, and relevant mechanisms. Results Of the 18 included articles involving 418 animal models of DN, 1, 2, 6, and 9 used dihydroartemisinin, artemether, artesunate, and artemisinin, respectively. Overall, artemisinins reduced indicators of renal function, including blood urea nitrogen (P < 0.00001), serum creatinine (P < 0.00001), and kidney index (P = 0.0001) compared with control group treatment. Measurements of proteinuria (P < 0.00001), microalbuminuria (P < 0.05), and protein excretion (P = 0.0002) suggested that treatment with artemisinins reduced protein loss in animals with DN. Artemisinins may lower blood glucose levels (P = 0.01), but there is a risk of weight gain (P < 0.00001). Possible mechanisms of action of artemisinins include delaying renal fibrosis, reducing oxidative stress, and exerting antiapoptotic and anti-inflammatory effects. Conclusion Available evidence suggests that artemisinins may be protective against renal injury secondary to diabetes in preclinical studies; however, high-quality and long-term trials are needed to reliably determine the balance of benefits and harms.

Abstract
Qingre Jiedu (QJ) recipe exerted significant cardioprotective efficacy against heart failure (HF), which is a growing health concern that continues to endanger patients' lives. To investigate the protective properties and mechanism of the QJ recipe, we established hydrogen peroxide (H2O2)-induced H9C2 cells and HF rats. The predicted targets and significant pathways of QJ against HF were collected and screened based on network pharmacology from key ingredients and validated by in vivo and in vitro experiments. The decoction of QJ (0.823 g/kg/day) was intragastrically administered for four weeks. QJ (400 μg/mL) was cultured with H2O2 stimulated in the H9C2 cells. A total of 31 effective active compounds were screened in QJ and covered 277 targets, of which 85 were shared with HF-related targets. In vivo, the QJ recipe remarkably protected heart function and reduced serum IL-1, IL-6, PIIINP, and CIV levels. Furthermore, QJ downregulated the key proteins mediating inflammatory responses (p-IKKα/β, p-NFκB, and IL-6) and cardiac fibrosis (STAT3 and MMP-9). In vitro, QJ protected the cardiomyocytes against H2O2-stimulated reactive oxygen species (ROS) production and upregulated PI3K and AKT expressions. Further experiments demonstrate that PI3K inhibitor LY294002 remarkably compromised the effects of QJ. In conclusion, our findings indicate that QJ could exert a cardioprotective effect and inhibit fibrosis and inflammation in HF rats via the PI3K-AKT signaling pathway.

Abstract
BACKGROUND Artemisinin (ART) is an anti-malaria natural compound with a moderate anticancer action. As a metabolite of ART, dihydroartemisinin (DHA) may have stronger anti-colorectal cancer (CRC) bioactivities. However, the effects of DHA and ART on CRC chemoprevention, including adaptive immune regulation, have not been systematically evaluated and compared. METHODS Coupled with a newly-established HPLC analytical method, enteric microbiome biotransformation was conducted to identify if the DHA is a gut microbial metabolite of ART. The anti-CRC potential of these compounds was compared using two different human CRC cell lines for cell cycle arrest, apoptotic induction, and anti-inflammation activities. Naive CD4+ T cells were also obtained for testing the compounds on the differentiation of Treg, Th1 and Th17. RESULTS Using compound extraction and analytical methods, we observed for the first time that ART completely converted into its metabolites by gut microbiome within 24 h, but no DHA was detected. Although ART did not obviously influence cancer cell growth in the concentration tested, DHA very significantly inhibited the cancer cell growth at relatively low concentrations. DHA included G2/M cell cycle arrest via upregulation of cyclin A and apoptosis. Both ART and DHA downregulated the pro-inflammatory cytokine expression. The DHA significantly promoted Treg cell proliferation, while both ART and DHA inhibited Th1 and Th17 cell differentiation. CONCLUSIONS As a metabolite of ART, DHA possessed stronger anti-CRC activities. The DHA significantly inhibited cell growth via cell cycle arrest, apoptosis induction and anti-inflammation actions. The adaptive immune regulation is a related mechanism of actions for the observed effects.

Front Endocrinol (Lausanne) 2022; 13:891922. [PMID: 35663306 PMCID: PMC9157422 DOI: 10.3389/fendo.2022.891922] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/08/2022] [Accepted: 03/31/2022] [Indexed: 11/13/2022] Open
Abstract
Graves' ophthalmopathy (GO) is a common orbital disease that threatens visual function and appearance. Orbital fibroblasts (OFs) are considered key target and effector cells in GO. In addition, hyaluronan (HA) production, inflammation, and orbital fibrosis are intimately linked to the pathogenesis of GO. In this study, we explored the therapeutic effects of dihydroartemisinin (DHA), an antimalarial drug, on GO-derived, primary OFs. CCK8 and EdU assays were applied to evaluate the antiproliferative effect of DHA on OFs. Wound healing assays were conducted to assess OF migration capacity, while qRT-PCR, western blotting, ELISA, and immunofluorescence were used to determine the expression of fibrosis-related and pro-inflammatory markers in these cells. Moreover, RNA sequencing was conducted to identify differentially expressed genes (DEGs) in DHA-treated OFs, and Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis of DEGs was performed to explore potential mechanisms mediating the antifibrotic effect of DHA on GO-derived OFs. Results showed that DHA dose-dependently inhibited OF proliferation and downregulated, at the mRNA and protein levels, TGF-β1-induced expression of fibrosis markers, including alpha smooth muscle actin (α-SMA) and connective tissue growth factor (CTGF). Furthermore, DHA inhibited TGF-β1 induced phosphorylation of extracellular signal-regulated protein kinase 1/2 (ERK1/2) and signal transducer and activator of transcription 3 (STAT3), which suggested that DHA exerted antifibrotic effects via suppression of the ERK and STAT3 signaling pathways. In addition, DHA suppressed the expression of pro-inflammatory cytokines and chemokines, including IL-6, IL-8, CXCL-1, MCP-1, and ICAM-1, and attenuated HA production induced by IL-1β in GO-derived OFs. In conclusion, our study provides first-time evidence that DHA may significantly alleviate pathogenic manifestations of GO by inhibiting proliferation, fibrosis- and inflammation-related gene expression, and HA production in OFs. These data suggest that DHA may be a promising candidate drug for treatment of GO.

Abstract
Psoriasis is a common chronic immune-mediated disease that often has a serious negative impact on the physical and mental health of patients. Dihydroartemisinin (DHA) is a drug with anti-fibrotic and anti-inflammatory effects that may be involved in the autoimmune regulation of immune diseases. However, the effects of DHA on psoriasis have not been reported comprehensively. Therefore, the aim of this study was to investigate the effect of DHA on abnormal proliferation and inflammation of epidermal keratinocyte cells in psoriasis and its mechanism of action. IL-17A-induced human epidermal keratin-forming cells (HaCaT) were used as a model. And after induction exposure to different concentrations of DHA, CCK-8, EDU staining, wound healing and Western blotting were performed to assess cell viability, proliferation, migration, differentiation and inflammatory factors, respectively. Subsequently, agonists of fibroblast growth factor receptor 1 (FGFR1) were added and the above experiments were repeated. The results showed that DHA obviously inhibited IL-17A-induced hyperproliferation, migration and expression of inflammatory factors in HaCaT cells. Furthermore, FGFR1 was highly expressed in IL-17A-induced HaCaT cells, and DHA inhibited its expression. However, the inhibitory effect of DHA on IL-17A-induced HaCaT cells was reversed after the addition of FGFR1 agonist. In conclusion, DHA could inhibit IL-17A-induced hyperproliferation and inflammation of keratinocytes by targeting FGFR1, which also provided a new target for the treatment of psoriasis.

Abstract
Morphine tolerance poses a great challenge for clinicians, whose pathogenesis has a close connection with microglial activation and neuroinflammation. Dihydroartemisinin (DHA) that derives from artemisinin, may serve as a potential anti-inflammatory drug. In this study, the effects as well as the underlying mechanism of DHA on suppressing microglial activation and neuroinflammation were explored. The microglial cell line BV-2 cells were induced by morphine and treated with DHA or minocycline. With the application of CCK-8, the cell viability was detected. Western blot was employed to assess the expressions of Ki67, IBa-1, and TLR4 and quantitative real-time PCR (qRT-PCR) was adopted to evaluate miRNA-16 (miR-16) expression. With the adoption of ELISA kits and qRT-PCR, the release of inflammatory cytokines was evaluated. Besides, luciferase reporter assay was applied to testify the binding relationship between miR-16 and TLR4. NF-κB expression was measured by immunofluorescence. DHA reduced cell viability and decreased protein expression of Ki67 and IBa-1 in morphine-induced BV-2 cells. Additionally, DHA contributed to the declined release of pro-inflammatory cytokines. miR-16 was down-regulated by morphine but was up-regulated by DHA concentration-dependently in BV-2 cells. The inhibition of miR-16 partly abolished the inhibitory effects of DHA on morphine-induced microglial activation and neuroinflammation. Moreover, TLR4 was found to be bound to miR-16, and the inhibitory effect of DHA on TLR4/NF-κB was partly reversed by miR-16 inhibition. In conclusion, DHA remarkably suppressed microglial activation and neuroinflammation through regulating miR-16-mediated TLR4/NF-κB signaling. This study may provide a new solution to improve clinical analgesic efficacy of morphine.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Aloe vera (L.) Burm. f. (Aloe vera) is a medicinal herb that used in Traditional Chinese Medicine (TCM) practice for the treatment of gastrointestinal diseases such as constipation and colitis. Recent studies also reported its beneficial effect in mitigating ulcerative colitis (UC). Nevertheless, the underlying mechanisms of Aloe vera against UC remain largely unknown. AIM OF THE STUDY This study aimed to explore a relation between the therapeutical effects of Aloe vera in UC and colonic mucus secretion, and further investigate the underlying pathways through which Aloe vera regulates colon mucus as well as preliminarily studied the main active constitute of Aloe vera to alleviate UC. MATERIALS AND METHODS UPLC-MS/MS were employed to analyze the Aloe vera extract. The rat models of UC were induced by free subjected to fresh 3% dextran sulfate sodium (DSS) solution for 8 days and then accessed to tap water for 2 days. Aloe vera extract (18 mg/kg and 72 mg/kg) or 5-ASA (400 mg/kg) was administered orally from day 1-10. At the end of experiment, rats were sacrificed and the colon tissues were harvested for analysis. UC symptoms was evaluated by disease activity index (DAI), colon length and H&E staining. The Alcian blue stain were determined colon mucus layer. Myeloperoxidase (MPO) activity, mucin and inflammatory cytokines in colon tissues were determined by ELISA. The expression of related proteins on PI3K/AKT and PKC/ERK signaling pathway was analyzed by Western blot. We then evaluated the effects of three main components of Aloe vera (Aloe-emodin, aloin A and B) on mucin secretion and cytokine expression in vitro by ELISA. RESULTS Oral supplement with Aloe vera extract resulted in a significantly decreased DSS-induced UC symptoms, including decreased DAI, prevention of the colon length shortening, and alleviation of the pathological changes occurring in colon. The expression of colonic pro-inflammatory mediators, including IL-6, IL-1β and TNF-α were suppressed, yet the expression of IL-10 was up-regulated by Aloe vera treatment. Moreover, Aloe vera significantly up-regulated the expressions of mucin proteins (e.g., MUC2 and MUC5AC) and increased the thickness of mucus layer in the colon. Further, we revealed that Aloe vera significantly upregulated p-PKC and p-ERK expression and downregulated p-PI3K and p-AKT expression. Finally, we discovered that treat with aloin A markedly decreased IL-6 levels and increased MUC2 expression in LPS-stimulated LS174T cell. CONCLUSION These results support that Aloe vera improved UC by enhancing colon mucus barrier functions in addition to reducing inflammation. Moreover, aloin A might be a main active components of Aloe vera to ameliorate UC.

Abstract
Dihydroartemisinin (DHA) has been globally recognized for its efficacy and safety in the clinical treatment of malaria for decades. Recently, it has been found that DHA inhibits malignant tumor growth and regulates immune system function in addition to anti-malaria. In parasites and tumors, DHA causes severe oxidative stress by inducing excessive reactive oxygen species production. DHA also kills tumor cells by inducing programmed cell death, blocking cell cycle and enhancing anti-tumor immunity. In addition, DHA inhibits inflammation by reducing the inflammatory cells infiltration and suppressing the production of pro-inflammatory cytokines. Further, genomics, proteomics, metabolomics and network pharmacology of DHA therapy provide the basis for elucidating the pharmacological effects of DHA. This review provides a summary of the recent research progress of DHA in anti-tumor, inhibition of inflammatory diseases and the relevant pharmacological mechanisms. With further research of DHA, it is likely that DHA will become an alternative therapy in the clinical treatment of malignant tumors and inflammatory diseases.

Abstract
Artemisinin and its derivatives (ARTs) are known as conventional antimalarial drugs with clinical safety and efficacy. Youyou Tu was awarded a Nobel Prize in Physiology and Medicine due to her discovery of artemisinin and its therapeutic effects on malaria. Apart from antimalarial effects, mounting evidence has demonstrated that ARTs exert therapeutic effects on inflammation and autoimmune disorders because of their anti-inflammatory and immunoregulatory properties. In this aspect, tremendous progress has been made during the past five to seven years. Therefore, the present review summarizes recent studies that have explored the anti-inflammatory and immunomodulatory effects of ARTs on autoimmune diseases and transplant rejection. In this review, we also discuss the cellular and molecular mechanisms underlying the immunomodulatory effects of ARTs. Recent preclinical studies will help lay the groundwork for clinical trials using ARTs to treat various immune-based disorders, especially autoimmune diseases.

Abstract
Activation of hepatic stellate cells (HSCs) is a central event in the pathogenesis of liver fibrosis and is often accompanied by the disappearance of lipid droplets (LDs). Although interference with LD metabolism can effectively reverse the activation of HSCs, there is currently no effective therapy for liver fibrosis. Our previous evidence indicates that long non-coding RNA (lncRNA)-H19 plays an essential role in LD metabolism of HSC. In this study, we investigated the potential molecular mechanism of dihydroartemisinin (DHA) inhibits LD metabolism and liver fibrosis by regulating H19-AMPK pathway. We found that DHA restores LDs content in activated HSCs via reducing the transcription of H19 driven by hypoxia inducible factor 1 subunit alpha (HIF1α) and inhibiting the lipid oxidation signal mediated by AMP-activated protein kinase (AMPK) phosphorylation. In vivo experiments, we have proved that DHA reduced the deposition of extracellular matrix (ECM) and reduce the level of liver fibrosis in CCl4-induced liver fibrosis of mice. In summary, our results emphasize the importance of H19 in liver fibrosis and the potential of DHA to regulate H19 to treat liver fibrosis, providing a new direction for the prevention and treatment of liver fibrosis.

Abstract
The sesquiterpene lactone artemisinin from Artemisia annua L. is well established for malaria therapy, but its bioactivity spectrum is much broader. In this review, we give a comprehensive and timely overview of the literature regarding the immunosuppressive activity of artemisinin-type compounds toward inflammatory and autoimmune diseases. Numerous receptor-coupled signaling pathways are inhibited by artemisinins, including the receptors for interleukin-1 (IL-1), tumor necrosis factor-α (TNF-α), β3-integrin, or RANKL, toll-like receptors and growth factor receptors. Among the receptor-coupled signal transducers are extracellular signal-regulated protein kinase (ERK), c-Jun N-terminal kinase (JNK), phosphatidylinositol-4,5-bisphosphate 3-kinase (PI3K), AKT serine/threonine kinase (AKT), mitogen-activated protein kinase (MAPK)/extracellular signal regulated kinase (ERK) kinase (MEK), phospholipase C γ1 (PLCγ), and others. All these receptors and signal transduction molecules are known to contribute to the inhibition of the transcription factor nuclear factor κ B (NF-κB). Artemisinins may inhibit NF-κB by silencing these upstream pathways and/or by direct binding to NF-κB. Numerous NF-κB-regulated downstream genes are downregulated by artemisinin and its derivatives, for example, cytokines, chemokines, and immune receptors, which regulate immune cell differentiation, apoptosis genes, proliferation-regulating genes, signal transducers, and genes involved in antioxidant stress response. In addition to the prominent role of NF-κB, other transcription factors are also inhibited by artemisinins (mammalian target of rapamycin [mTOR], activating protein 1 [AP1]/FBJ murine osteosarcoma viral oncogene homologue [FOS]/JUN oncogenic transcription factor [JUN]), hypoxia-induced factor 1α (HIF-1α), nuclear factor of activated T cells c1 (NF-ATC1), Signal transducers and activators of transcription (STAT), NF E2-related factor-2 (NRF-2), retinoic-acid-receptor-related orphan nuclear receptor γ (ROR-γt), and forkhead box P-3 (FOXP-3). Many in vivo experiments in disease-relevant animal models demonstrate therapeutic efficacy of artemisinin-type drugs against rheumatic diseases (rheumatoid arthritis, osteoarthritis, lupus erythematosus, arthrosis, and gout), lung diseases (asthma, acute lung injury, and pulmonary fibrosis), neurological diseases (autoimmune encephalitis, Alzheimer's disease, and myasthenia gravis), skin diseases (dermatitis, rosacea, and psoriasis), inflammatory bowel disease, and other inflammatory and autoimmune diseases. Randomized clinical trials should be conducted in the future to translate the plethora of preclinical results into clinical practice.

Abstract
Although tumor necrosis factor-α (TNF-α) is a known major inflammatory mediator in inflammatory bowel disease (IBD) and has various effects on intestinal epithelial cell (IEC) homeostasis, the changes in IECs in the early inflammatory state induced during short-time treatment (24 h) with TNF-α remain unclear. In this study, we investigated TNF-α-induced alterations in IECs in the early inflammatory state using mouse jejunal organoids (enteroids). Of the inflammatory cytokines, i.e., TNF-α, IL-1β, IL-6, and IL-17, only TNF-α markedly increased the mRNA level of macrophage inflammatory protein 2 (MIP-2; the mouse homologue of interleukin-8), which is induced in the early stages of inflammation. TNF-α stimulation (3 h and 6 h) decreased the mRNA level of the stem cell markers leucine-rich repeat-containing G-protein-coupled receptor 5 (Lgr5) and polycomb group ring finger 4 and the progenitor cell marker prominin-1, which is also known as CD133. In addition, TNF-α treatment (24 h) decreased the number of Lgr5-positive cells and enteroid proliferation. TNF-α stimulation at 3 h and 6 h also decreased the mRNA level of chromogranin A and mucin 2, which are respective markers of enteroendocrine and goblet cells. Moreover, enteroids treated with TNF-α (24 h) not only decreased the integrity of tight junctions and cytoskeletal components but also increased intercellular permeability in an influx test with fluorescent dextran, indicating disrupted intestinal barrier function. Taken together, our findings indicate that short-time treatment with TNF-α promotes the inflammatory response and decreases intestinal stem cell activity and barrier function.

Abstract
Colitis-associated colorectal cancer (CAC) develops from chronic intestinal inflammation. Dihydroartemisinin (DHA) is an antimalarial drug exhibiting anti-inflammatory and anti-tumor effects. Nonetheless, the therapeutic effects of DHA on CAC remain unestablished. Methods: Mice were challenged with azoxymethane (AOM) and dextran sulfate sodium (DSS) to establish CAC models. DHA was administered via oral gavage in different stages of CAC models. Colon and tumor tissues were obtained from the AOM/DSS models to investigate inflammatory responses and tumor development. Inflammatory cytokines in the murine models were detected through qRT-PCR and ELISA. Toll-like receptor 4 (TLR4) signaling-related proteins were detected by western blot. Macrophage infiltration was measured using immunostaining analysis, and apoptosis in the colon cancer cells was detected by flow cytometry and western blot. Results: DHA inhibited inflammatory responses in the early stage of the AOM/DSS model and subsequent tumor formation. In the early stage, DHA reversed macrophage infiltration in colon mucosa and decreased the expression of pro-inflammatory cytokines. DHA inhibited the activation of macrophage by suppressing the TLR4 signal pathway. In the late stage of CAC, DHA inhibited tumor growth by enhancing cell cycle arrest and apoptosis in tumor cells. Administration of DHA during the whole period of the AOM/DSS model generated an addictive effect based on the inhibition of inflammation and tumor growth, thereby improving the therapeutic effect of DHA on CAC. Conclusion: Our study indicated that DHA could be a potent agent in managing the initiation and development of CAC without obvious side effects, warranting further clinical translation of DHA for CAC treatment.

Abstract
Ulcerative colitis (UC) is a form of inflammatory bowel disease, which manifests as irritation or swelling and sores in the large intestine in a relapsing and remitting manner. In a dextran sulfate sodium sulfate (DSS)-induced UC model in female mice, we found that the levels of cyclic guanosine monophosphate (cGMP) are reduced, while the expression of phosphodiesterase 9A (PDE9A) is highest among all phosphodiesterase (PDEs). Since PDE9 has the highest affinity toward cGMP, we evaluated the selective PDE9 inhibitor PF-04447943 (PF) as a potential candidate for UC treatment. PF has been extensively studies in cognitive function and in sickle cell disease, but not in models for inflammatory bowel disease (IBD). Therefore, we used female C57BL/6 mice treated with 3% DSS alone or co-treated with PF or sulfasalazine (SASP) to study the body weight, colon length, histopathology, and measure superoxide dismutase (SOD), malondialdehyde (MDA), and cGMP level, as well as cytokines such as tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), interleukin-17 (IL-17), interleukin-12/23 (IL-12/23), interleukin-10 (IL-10), and pathways including nuclear factor kappa B (NF-κB), signal transducer and activator of transcription 3 (STAT3), and inflammasome activation. In addition, the number of dendritic cells (DC) and regulatory T cells (Treg cell) was assessed in the spleen, lymph node, and colon using flow cytometry. DSS reduced the number of goblet cells, decreased colon lengths and body weights, all of them were attenuated by PF treatment. It also suppressed the elevated level of inflammatory cytokines and increased level the anti-inflammatory cytokine, IL-10. PF treatment also reduced the DSS-induced inflammation by suppressing oxidative stress, NF-κB, STAT3, and inflammasome activation, by upregulating nuclear factor erythroid 2-related factor 2 (Nrf-2) and its downstream proteins via extracellular signal-regulated kinase (ERK) phosphorylation. Importantly, PF reversed imbalance in Treg/T helper 17 cells (Th17) cells ratio, possibly by regulating dendritic cells and Treg developmental process. In summary, this study shows the protective effect of a PDE9A inhibitor in ulcerative colitis by suppressing oxidative stress and inflammation as well as reversing the Treg/Th17 cells imbalance.

Vildagliptin attenuates acetic acid-induced colitis in rats via targeting PI3K/Akt/NFκB, Nrf2 and CREB signaling pathways and the expression of lncRNA IFNG-AS1 and miR-146a. Int Immunopharmacol 2021; 92:107354.

Abstract
Inflammatory processes, including ulcerative colitis (UC), are associated with the increase in synthesis and release of pro-inflammatory cytokines. The release of these cytokines is regulated by phosphatidylinositol-3-kinase (PI3K)/protein kinase B (Akt)/nuclear factor-kappa B (NFκB) and cAMP response element-binding protein (CREB) signaling pathways as well as over expression of microRNA 146a (miR-146a) and long non-coding RNA interferon gamma antisense 1 (lncRNA IFNG-AS1). Vildagliptin (Vilda), a dipeptidyl peptidase IV (DPP-IV) inhibitor, has an anti-inflammatory, antioxidant and anti-apoptotic effects which were established in various models. However, its possible protective effect in UC has not been clarified. Hence, the current study aimed to explore the possible prophylactic effect of different doses of Vilda against acetic acid (AA)-induced colitis in rats. Forty-eight adult Wistar rats were divided into six groups: control, Vilda (10 mg/kg/day; p.o.), AA, AA + Vilda (5 mg/kg/day; p.o.), AA + Vilda (10 mg/kg/day; p.o.) and AA + sulfasalazine (Sulfa) (100 mg/kg/day; p.o.).Low- and high-dose Vilda showed significant improvement in the disease activity index (DAI) and macroscopic assessment markers. Vilda has markedly inhibited the expression of lncRNA IFNG-AS1 and miR-146a, as well as PI3K/Akt/NFκB pathway, while activated CREB and nuclear factor erythroid 2-related factor 2 (Nrf2) signaling pathways, and this was reflected in alleviated oxidative stress, inflammation and apoptosis. Such outcomes were more prominent with the high-dose Vilda versus low-dose Vilda and Sulfa. Moreover, the histological examination showed almost intact histological features in Vilda-treated groups when compared to AA group treated with saline. In conclusion, Vilda can be regarded as a new promising therapeutic alternative against UC.

Abstract
Background: Radix Sophorae flavescentis (Kushen), a Chinese herb, is widely used in the treatment of ulcerative colitis (UC) with damp-heat accumulation syndrome (DHAS) according to traditional Chinese medicine (TCM) theory. Objective: The aim of this study was to illuminate the clinical efficacy and potential mechanisms of Kushen-based TCM formulations in the treatment of UC with DHAS. Materials and Methods: A systematic literature search was performed in the PubMed, EMBASE, Chinese Biomedical Literature database, China National Knowledge Infrastructure database, Chongqing VIP Information database, and Wanfang database for articles published between January 2000 and July 2020 on randomized controlled trials (RCTs) that used Kushen-based TCM formulations in the treatment of UC with DHAS. A network pharmacology approach was conducted to detect the potential pathways of Kushen against UC with DHAS. Results: Eight RCTs with a total of 983 subjects were included in the meta-analysis. Compared with the control subjects (5-aminosalicylic acid therapy), those who received Kushen-based TCM formulations for the treatment of UC showed a significantly higher clinical remission rate (RR = 1.20, 95% CI: [1.04, 1.38], p = 0.02) and lower incidence of adverse events (RR = 0.63, 95% CI [0.39, 1.01], p = 0.06). A component-target-pathway network was constructed, indicating five main components (quercetin, luteolin, matrine, formononetin, and phaseolin), three major targets (Interleukin-6, Myc proto-oncogene protein, and G1/S-specific cyclin-D1) and one key potential therapeutic pathway (PI3K-Akt signaling) of Kushen against UC with DHAS. Conclusion: Kushen-based TCM formulations provide good efficacy and possess great potential in the treatment of UC. Large-scale and high-quality clinical trials and experimental verification should be considered for further confirmation of the efficacy of Kushen-based formulations.

Dihydroartemisinin prevents dextran sodium sulphate-induced colitisthrough inhibition of the activation of NLRP3 inflammasome and p38 MAPK signaling. Int Immunopharmacol 2020; 88:106949.

Abstract
Dihydroartemisinin (DHA), a sesquiterpene lactone derived from artemisinin, has been reported to possess anti-inflammation and anti-cancer activities. But its underlying protective mechanisms on dextran sodium sulphate (DSS)-induced colitis remain rarely reported. We applied a network pharmacology approach to predict the collective targets of DHA and acute colitis. GO and KEGG analyses were performed to investigate the enriched biological functions and signaling pathways of the collective targets. Furthermore, a DSS-induced colitis model was established to observe the protective effects of DHA. 83 common targets of DHA and acute colitis were identified and predominantly involved in several inflammation-related signaling pathways in colitis such as NOD-like receptor and MAPK signaling pathways. Additionally, DHA in vivo improved the clinical symptoms, reduced the production of pro-inflammatory factors IL-1β, IL-6 and TNF-α, and suppressed the formation of NLRP3 inflammasome. Moreover, DHA inhibited the phosphorylation of NF-κB p65 and p38 MAPK, but upregulated PPARγ and Ki-67 levels compared to the DSS group. Additionally, we found that DHA suppressed p38 activator-induced pro-inflammatory response, and p38 inhibitor attenuated the clinical symptoms and reduced the expression levels of pro-inflammatory mediators and NLRP3 while up-regulated the expression levels of PPARγ and Ki-67. Molecular docking analysis further verified the binding mode towards the DHA and p38 MAPK. In conclusion, DHA could protect DSS-induced colitis via suppressing the activation of NLRP3 inflammasome and p38 MAPK signaling.

Abstract
Inflammation and the proliferation of vascular smooth muscle cells (VSMCs) are seen to play critical roles in the development of vascular complications induced by diabetes and hyperglycemia. Dihydroartemisinin (DHA) has been identified as a semi-synthetic derivative of artemisinin that exhibits broad protective effects. However, the effect of DHA on high glucose (HG)-induced inflammation and proliferation of VSMCs remains unknown. Therefore, this study aims to show that DHA significantly inhibited the proliferation of VSMCs and that expression of the inflammatory cytokines IL-1β and TNF-α was induced by HG in a dose-dependent manner. Additionally, we were able to determine that KLF15 played a critical role in HG-induced VSMC proliferation and inflammation, confirming its protective effects observed after DHA treatment in the HG-induced inflammatory response of VSMCs. DHA was observed to directly depress the HG-induced expression of miR-376b-3p, which targeted the 3'-UTR of KLF15 and inhibited its expression. These results suggested that DHA plays a protective role in HG-induced VSMC proliferation and associated inflammation by inhibiting the miR-376b-3p/KLF15 axis. Our findings provide new evidence of the mechanisms of DHA and its critical role in treating the pathogenesis of diabetic vascular complications.

Low-dose interleukin-2 alleviates dextran sodium sulfate-induced colitis in mice by recovering intestinal integrity and inhibiting AKT-dependent pathways. Theranostics 2020; 10:5048-5063.

Abstract
Several phase 1/2 clinical trials showed that low-dose interleukin-2 (IL-2) treatment is a safe and effective strategy for the treatment of chronic graft-versus-host disease, hepatitis C virus-induced vasculitis, and type 1 diabetes. Ulcerative colitis (UC) is a chronic inflammatory condition of the colon that lacks satisfactory treatment. In this study, we aimed to determine the effects of low-dose IL-2 as a therapeutic for UC on dextran sulfate sodium (DSS)-induced colitis. Methods: Mice with DSS-induced colitis were intraperitoneally injected with low-dose IL-2. Survival, body weight, disease activity index, colon length, histopathological score, myeloperoxidase activity and inflammatory cytokine levels as well as intestinal barrier integrity were examined. Differential gene expression after low-dose IL-2 treatment was analyzed by RNA-sequencing. Results: Low-dose IL-2 significantly improved the symptoms of DSS-induced colitis in mice and attenuated pro-inflammatory cytokine production and immune cell infiltration. The most effective dose range of IL-2 was 16K-32K IU/day. Importantly, low-dose IL-2 was effective in ameliorating the disruption of epithelial barrier integrity in DSS-induced colitis tissues by restoring tight junction proteins and mucin production and suppressing apoptosis. The colon tissue of DSS-induced mice exposed to low-dose IL-2 mimic gene expression patterns in the colons of control mice. Furthermore, we identified the crucial role of the PI3K-AKT pathway in exerting the therapeutic effect of low-dose IL-2. Conclusions: The results of our study suggest that low-dose IL-2 has therapeutic effects on DSS-induced colitis and potential clinical value in treating UC.
