PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2024; 132:155866. [PMID: 39053247 DOI: 10.1016/j.phymed.2024.155866] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/27/2023] [Revised: 07/04/2024] [Accepted: 07/08/2024] [Indexed: 07/27/2024]
Abstract
BACKGROUND Gastric ulcer (GU) is a common gastrointestinal disease with high morbidity that may be caused by various pathogenic factors. Dan-Shen-Yin (DSY), a traditional prescription, improves myocardial and gastrointestinal functions; however, its effect on GU and the underlying mechanisms requires further research. PURPOSE We aimed to evaluate the pharmacodynamics of DSY granules in GU using three different animal models and explore their potential mechanisms. METHODS DSY granules were manufactured and subjected to quality control by high-performance liquid chromatography (HPLC). Three GU models were established using ethanol, aspirin, or water immersion restraint combined with aspirin and examined using the Guth method and hematoxylin and eosin (H&E) staining. The effects of DSY granules on gastric mucosal glycoproteins and the release of defensive and aggressive factors in ethanol-induced GU were measured using periodic acid-Schiff (PAS) staining and ELISA. TUNEL staining and detection of apoptosis-related proteins were used to evaluate the role of DSY granules on apoptosis. Potential mechanisms were predicted using network pharmacology, molecular docking, and western blot to verify the related targets and pathways. RESULTS DSY granules were prepared for the first time and quality control standard was established. Pharmacodynamic evaluation indicated that DSY granules significantly reduced the GU index and gastric mucosal injury in the three GU models, and the GU inhibition rate of DSY granules was superior to omeprazole in ethanol-induced GU model (60.32 % vs. 21.96 %). Further studies in ethanol-induced GU model revealed that DSY granules increased the levels of the defensive factors (PGE2, NO, SOD, CAT, TAOC, and GSH) and decreased the levels of aggressive factors (MDA, TNF-α, and IL-1β), thereby inhibiting oxidative stress and inflammation, attenuating gastric mucosal injury. Moreover, the results of TUNEL staining and western blot showed that DSY granules suppressed apoptosis by reducing the ratios of Bax/Bcl-2 and cleaved-Caspase-3/Caspase-3. In addition, the results of network pharmacology and molecular docking suggested that the mechanisms of DSY granules against GU may be related to the Akt-related signaling pathway. Further study confirmed that DSY granules significantly reduced the ratio of p-Akt/Akt and promoted the expression of Nrf2 and NQO1, protecting the gastric mucosa. CONCLUSIONS Our results indicated that DSY granules had protective effects on GU caused by different mechanisms, especially ethanol-induced GU. DSY granules alleviated gastric mucosal damage by inhibiting oxidative stress, inflammation, and apoptosis, which may be associated with the regulation of Akt/Nrf2 signaling pathway. Therefore, DSY granules may be a promising drug for the treatment of GU.

Characterization of active alkaloids and metabolites in rats after oral administration of Zuojin Pill using UHPLC-Q-TOF-MS combined with bioinformatics and molecular docking analyses. J Pharm Biomed Anal 2024; 249:116340. [PMID: 38986349 DOI: 10.1016/j.jpba.2024.116340] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2024] [Revised: 06/18/2024] [Accepted: 07/03/2024] [Indexed: 07/12/2024]
Abstract
Zuojin Pill (ZJP), a traditional Chinese medicine prescription composed of Rhizoma Coptidis and Euodiae Fructus in the ratio of 6:1 (w/w), has been widely used for the treatment of gastric disorders. However, an in-depth understanding of in vivo metabolism and distribution profiles of protoberberine alkaloids (PBAs) and indole alkaloids (IDAs) in ZJP is lacking. In this study, a method using ultra-high performance liquid chromatography coupled with quadruple time-of-flight mass spectrometry (UHPLC-Q-TOF-MS) was developed to systematically screen the alkaloids and their metabolites in rat plasma and various tissues after oral administration of ZJP. Furthermore, bioinformatics and molecular docking analyses were conducted to elucidate the contribution of the alkaloids and metabolites enriched in the stomach to the therapeutic effect of ZJP on gastritis. A total of 33 compounds, including 7 prototype alkaloids and 26 metabolites, were chemically defined or tentatively identified in this work. The metabolic pathways of PBAs (hydroxylation, oxidation, reduction, demethylation, demethylenation, glucuronide conjugation, sulfate conjugation) and IDAs (hydroxylation, glucuronide conjugation) were revealed. Notably, 7 prototype alkaloids and 18 metabolites were detected in the stomach, indicating their propensity for gastric distribution. These alkaloids and metabolites showed strong affinities with the 7 hub targets associated with gastritis, such as CCR7, CXCR4, IL6, IFNG, CCL2, TNF, and PTPRC, and could be considered the potential active substances of ZJP for treating gastritis. In conclusion, this study clarified the gastric distribution propensity of PBAs and IDAs and their metabolites, as well as their favorable binding interactions with gastritis-related targets, which could provide essential data for the further study of the pharmacodynamic material basis and gastroprotective mechanism of ZJP.

Abstract
BACKGROUND Around the world, there is a high incidence of gastric ulcers. YS, an extract from the Chinese herb Albizzia chinensis (Osbeck) Merr, has potential therapeutic applications for gastrointestinal diseases. Here we elucidated the protective effect and underlying mechanism of action of YS on gastric ulcer in rats injured by ethanol. METHODS The ethanol-induced gastric ulcer rat model was used to assess the protective effect of YS. A pathological examination of gastric tissue was performed by H&E staining. GES-1 cells damaged by hydrogen peroxide were used to simulate oxidative damage in gastric mucosal epithelial cells. Endogenous NRF2 was knocked down using small interfering RNA. Immunoprecipitation was used to detect ubiquitination of NRF2. Co-immunoprecipitation was used to detect the NRF2-Keap1 interaction. RESULTS YS (10 and 30 mg/kg, i.g.) significantly reduced the ulcer index, decreased MDA level, and increased SOD and GSH levels in gastric tissues damaged by ethanol. YS promoted NRF2 translocation from cytoplasm to nucleus and enhanced the NQO1 and HO-1 expression levels in injured rat gastric tissue. In addition, YS regulated NQO1 and HO-1 via NRF2 in H2O2-induced oxidative injured GES-1 cells. Further studies on the underlying mechanism indicated that YS reduced the interaction between NRF2 and Keap1 and decreased ubiquitylation of NRF2, thereby increasing its stability and expression of downstream factors. NRF2 knockdown abolished the effect of YS on MDA and SOD in GES-1 cells treated with H2O2. CONCLUSION YS reduced the NRF2-Keap1 interaction, promoting NRF2 translocation into the nucleus, which increasing the transcription and translation of NQO1 and HO-1 and improved the antioxidant capacity of rat stomach.

Abstract
BACKGROUND Gastric mucosal injury is a chronic and progressive stomach disease that can be caused by nonsteroidal anti-inflammatory drugs (NSAIDs). Therefore, there is an urgent need to find safe and effective drugs to prevent gastric mucosal injury due to NSAIDs. Cinnamaldehyde (CA) is a bioactive compound extracted from the rhizome of cinnamon and has various pharmacological functions, including anti-inflammatory, analgesic, antiapoptotic, and antioxidant activities. However, the potential pharmacological effect of CA on gastric mucosal injury remains unknown. PURPOSE The aim of this study was to investigate the protective effects of CA on aspirin-induced gastric mucosal injury and to explore its mechanism of action METHODS: The effect of CA on gastric mucosal injury was investigated in vitro and in vivo, in vitro mouse model of gastric mucosal injury induced by aspirin, in vitro model of GES-1 cell injury by aspirin and Erastin. The mechanism of action of CA was determined using Transcriptomics and bioinformatics. RESULTS CA exerted its protective effects against gastric mucosal injury by modulating the downstream targets, including mTOR, GSK3β, and NRF2, via the PI3K/AKT signaling pathway to inhibit autophagy, apoptosis, and ferroptosis in the gastric epithelial cells. Further cellular experiments confirmed that the PI3K/AKT pathway was a key target for CA against gastric mucosal injury. CONCLUSION This study provides the first evidence of CA, an active compound in cinnamon, possessing therapeutic potential in preventing and treating gastric mucosal injury, with its mechanism involving the regulation of apoptosis, autophagy, and ferroptosis in gastric epithelial cells mediated by the PI3K/AKT signaling pathway.

Abstract
Cinnamomum cassia (cassia) is a tropical aromatic evergreen tree of the Lauraceae family well known for its fragrance and spicy flavor and widely used in Asian traditional medicine. It has recently garnered attention for its diverse potential health benefits, including anti-inflammatory, anti-cancer, and anti-diabetic properties. However, the gastroprotective effect of C. cassia, particularly against ethanol-induced gastric damage, remains unclear. We investigated the potential gastroprotective property of C. cassia and the underlying mechanisms of action in a rat model of ethanol-induced gastric injury. To assess its effectiveness, rats were fed C. cassia for a 14-day period prior to inducing gastric damage by oral administration of ethanol. Our results indicated that pre-treatment with C. cassia mitigated ethanol-induced gastric mucosal lesions and bleeding. Reduced gastric acid secretion and expression of acid secretion-linked receptors were also observed. Additionally, pretreatment with C. cassia led to decreased levels of inflammatory factors, including TNF-α, p-p65, and IκBα. Notably, C. cassia upregulated the expressions of HO1 and HSP90, with particular emphasis on the enhanced expression of PAS and MUC, the crucial gastric mucosa defense molecules. These findings suggest that C. cassia has protective effects on the gastric mucosa and can effectively reduce oxidative stress and inflammation.

Abstract
Cellular senescence plays a very important role in the ageing of organisms and age-related diseases that increase with age, a process that involves physiological, structural, biochemical and molecular changes in cells. In recent years, it has been found that the active ingredients of herbs and their natural products can prevent and control cellular senescence by affecting telomerase activity, oxidative stress response, autophagy, mitochondrial disorders, DNA damage, inflammatory response, metabolism, intestinal flora, and other factors. In this paper, we review the research information on the prevention and control of cellular senescence in Chinese herbal medicine through computer searches of PubMed, Web of Science, Science Direct and CNKI databases.

Abstract
CONTEXT Xiaojianzhong decoction (XJZD), classically prescribed in Chinese medicine, has protective and healing effects on gastric mucosal injury. However, the exact mechanism behind this effect remains unclear. OBJECTIVE To investigate the effect of XJZD on gastric mucosal injury and explore its underlying mechanisms. MATERIALS AND METHODS C57BL/6 mice were randomized into six groups (n = 10): the control group receiving sterile water, the model (aspirin 300 mg/kg), the XJZD high-dose (12 g/kg), XJZD medium-dose (6 g/kg), XJZD low-dose (3 g/kg) and omeprazole (20 mg/kg) groups, by gavage daily for 14 days. The area of gastric mucosal injury, mucosal injury index and degree of histopathological damage were analysed. Gastric mucosal epithelial cell apoptosis was detected. Epithelial cell autophagy was observed. The expression levels of tight junction proteins and proteins related to apoptosis, autophagy and the pentose phosphate pathway were analysed. RESULTS The results showed that after treatment with XJZD (12, 6 and 3 g/kg), the mucosal injury area was reduced (83.4%, 22.6% and 11.3%), the expression level of ZO-1 and occludin was up-regulated, the apoptosis rate of epithelial cells was reduced (40.8%, 25.4% and 8.7%), the expression of autophagy-related proteins LC3 and Beclin1 was decreased and the expression of p62 was increased, the PI3K/AKT/mTOR/ULK1(ser757) signalling pathway was activated, and the AMPK/ULK1(ser317) signalling pathway was inhibited. In addition, XJZD can antagonize the imbalance of redox homeostasis caused by aspirin and protect the gastric mucosa. DISCUSSION AND CONCLUSIONS XJZD protects against aspirin-induced gastric mucosal injury, implying it to be a potential therapeutic agent.

Abstract
Objective Chronic non-atrophic gastritis (CNAG) is a common clinical gastrointestinal disease with a long and recurrent course. In China, Wuzhuyu decoction (WZYD) has been used for centuries to treat gastrointestinal disorders. To unravel the efficacy and mechanism of WZYD for CNAG, a clinical study was conducted. And metabolomics was used to explore the mechanism of WZYD for CNAG patients. Methods Twenty patients in total were recruited in this study (Nos. ChiCTR2200062296) and the protocol was approved by the Ethics Committee (Approval number: KY-2022-2-6-1) and complied with the Declaration of Helsinki. The formula granule of WZYD were assessed by UHPLC-QQQ-TOF to discern the main potential active compounds. The endoscopy evaluation and histopathological changes were detected as effective indicators. Serum samples from patients were used for metabolomics. Inflammatory factors in patients' serum were determined by ELISA. Metabolomics revealed a series of differential metabolites and signaling pathways. Results WZYD was capable to prevent CNAG by ameliorating score of endoscopy evaluation including erosion, hemorrhage, as well as chronic inflammation and active chronic inflammation score after treatment were decreased. The results indicated that 10 core metabolic components were associated with the treatment of WZYD. Moreover, these metabolic components proved that pyrimidine metabolism and thiamine metabolism were critically responsible for CNAG. In addition, WZYD treatment effectively reduced serum levels of TNF-α, IL-10, and COX-2. Conclusion Altogether, WZYD can effectively alleviate CNAG by inhibiting inflammation and regulating related metabolic processes, which might be the molecular mechanism of WZYD treatment of CNAG. More studies are warranted to be conducted in this area. Trial Registration ChiCTR, ChiCTR2200062296. Registered 1 August 2022, https://www.chictr.org.cn/com/25/showprojen.aspx?proj=174027.

Gastroprotective 2-(2-phenylethyl)chromone-sesquiterpene hybrids from the resinous wood of Aquilaria sinensis (Lour.) Gilg. Bioorg Chem 2023; 133:106396. [PMID: 36758274 DOI: 10.1016/j.bioorg.2023.106396] [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: 12/06/2022] [Revised: 01/16/2023] [Accepted: 01/26/2023] [Indexed: 01/31/2023]
Abstract
Six previously unprecedented 2-(2-phenylethyl)chromone-sesquiterpene hybrids, aquisinenins A-F (1 - 6), were isolated from the resinous wood of Aquilaria sinensis by a LC-MS-guided fractionation procedure. Their structures were determined by extensive spectroscopic analysis (1D and 2D NMR, UV, IR, and HRMS) and experimental and computed ECD data. Compounds 1 - 6 were rare dimeric 2-(2-phenylethyl)chromone-sesquiterpene derivatives featuring 5,6,7,8-tetrahydro-2-(2-phenylethyl)chromone hybridized with different sesquiterpene (eudesmane/guaiane type) moieties via ester bond. Furthermore, all the isolated compounds were evaluated for their protective effects on taurocholic acid (TCA)-induced GES-1 cell injury. The most effective aquisinenin F (6) was used to elucidate the involved mechanism on protection against TCA-induced gastric mucosal damage. Our results indicated that 6 protected against gastric mucosal cell insult by downregulation of the ER stress triggered by TCA.

Untargeted serum and liver metabolomics analyses reveal the gastroprotective effect of polysaccharide from Evodiae fructus on ethanol-induced gastric ulcer in mice. Int J Biol Macromol 2023; 232:123481. [PMID: 36731690 DOI: 10.1016/j.ijbiomac.2023.123481] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2022] [Revised: 01/20/2023] [Accepted: 01/26/2023] [Indexed: 01/31/2023]
Abstract
This study aimed at investigating the gastroprotective effect of Evodiae fructus polysaccharide (EFP) against ethanol-induced gastric ulcer in mice. Biochemical indexes along with untargeted serum and liver metabolomics were determined. Results showed that pre-treatment of EFP alleviated ethanol-induced gastric ulcer in mice. EFP lessened oxidative stress and inflammation levels of stomachs, showing as increments of SOD and GSH-Px activities, GSH content and IL-10 level, and reductions of MDA and IL-6 levels. Meanwhile, EFP activated the Keap1/Nrf2/HO-1 signaling pathway through increasing Nrf2 and HO-1 protein expressions, and decreasing Keap1 protein expression. Serum and liver metabolomics analyses indicated that 10 metabolic potential biomarkers were identified among normal control, ulcer control and 200 mg/kg·bw of EFP groups, which were related to 5 enriched metabolic pathways including vitamin B6 metabolism, nicotinate and nicotinamide metabolism, pentose phosphate pathway, bile secretion and ascorbate and aldarate metabolism. Further pearson's correlation analysis indicated that there were some positive and negative correlations between the biomarkers and the biochemical indexes. It could be concluded that the gastroprotection of EFP might be related to anti-oxidative stress, anti-inflammation, activation of Keap1/Nrf2/HO-1 signaling pathway and alteration of metabolic pathways. This study supports the potential application of EFP in preventing ethanol-induced gastric ulcer.

A Network Pharmacology Method Combined with Molecular Docking Verification to Explore the Therapeutic Mechanisms Underlying Simiao Pill Herbal Medicine against Hyperuricemia. BIOMED RESEARCH INTERNATIONAL 2023; 2023:2507683. [PMID: 36817858 PMCID: PMC9935928 DOI: 10.1155/2023/2507683] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 09/07/2022] [Revised: 10/17/2022] [Accepted: 10/19/2022] [Indexed: 02/11/2023]
Abstract
Objective Hyperuricemia (HUA) is a common metabolic disease caused by disordered purine metabolism. We aim to reveal the mechanisms underlying the anti-HUA function of Simiao pill and provide therapeutic targets. Methods Simiao pill-related targets were obtained using Herbal Ingredients' Targets (HIT), Traditional Chinese Medicine Systems Pharmacology (TCMSP), and Traditional Chinese Medicine Integrated Database (TCMID). HUA-associated targets were retrieved from GeneCards, DisGeNET, and Therapeutic Targets Database (TTD). Protein-protein interaction (PPI) network was constructed using the Search Tool for the Retrieval of Interacting Genes/Proteins (STRING) database, ggraph and igraph R packages. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses were performed using ClusterProfiler. The top 10 core targets were identified through cytoHubba. Molecular docking was conducted using PyMOL and AutoDock high-performance liquid chromatograph (HPLC) analysis was performed to identify effective compounds of Simiao pill. Results Simiao pill-HUA target network contained 80 targets. The key targets were mainly involved in inflammatory responses. Insulin (INS), tumor necrosis factor (TNF), interleukin-6 (IL6), interleukin 1 beta (IL1B), vascular endothelial growth factor A (VEGFA), leptin (LEP), signal transducer and activator of transcription 3 (STAT3), C-C motif chemokine ligand 2 (CCL2), interleukin-10 (IL10), and toll like receptor 4 (TLR4) were the top 10 targets in the PPI network. GO analysis demonstrated the main implication of the targets in molecular responses, production, and metabolism. KEGG analysis revealed that Simiao pill might mitigate HUA through advanced glycation end-product- (AGE-) receptor for AGE- (RAGE-) and hypoxia-inducible factor-1- (HIF-1-) associated pathways. IL1B, IL6, IL10, TLR4, and TNF were finally determined as the promising targets of Simiao pill treating HUA. Through molecular docking and HPLC analysis, luteolin, quercetin, rutaecarpine, baicalin, and atractylenolide I were the main active compounds. Conclusions Simiao pill can mitigate HUA by restraining inflammation, mediating AGE-RAGE- and HIF-1-related pathways, and targeting IL1B, IL6, IL10, TLR4, and TNF.

Abstract
BACKGROUND Gastric mucosal injury caused by ethanol is a common gastrointestinal disease. Quinoa (Chenopodium quinoa Willd.), as a nutrient-rich grain, plays a significant role in preventing and treating gastric mucosal damage. The present study aimed to explore the protective effect of quinoa on alcohol-induced gastric mucosal damage and its possible mechanism. RESULTS The ethanol-induced gastric mucosal injury rat model was used for in vivo experiments and H2 O2 -induced GES-1 cells for in vitro experiments to elucidate the protective effect of quinoa. The results show that quinoa water extract can increase the superoxide dismutase level and decrease the malondialdehyde level in vitro and in vivo. Furthermore, quinoa also reduced the bleeding point and bleeding area in rats with ethanol-induced gastric mucosal injury and improved gastric histopathological changes. H2 O2 significantly increased the levels of inflammatory factors in GES-1 cells, which were markedly ameliorated by quinoa water extract. Likewise, quinoa water extract regulated the protein expression levels of Nrf2, Keap1, HO-1, p-IKK, and p-NF-κB through Nrf2 and nuclear factor-κB signaling pathways, reducing the production of oxidative stress and inflammation, thereby repairing the damaged gastric mucosa. CONCLUSION The findings of this study demonstrated that quinoa shows protective effect against ethanol-induced gastric mucosal injury through its anti-inflammatory and anti-oxidant effects. We propose that our research will provide a reference for quinoa as a functional food. © 2022 Society of Chemical Industry.

Abstract
Capsaicin (CAP) is an alkaloid isolated from pepper fruit, which possesses various pharmacological activities including antioxidant, anti-inflammatory, antibacterial and gastric mucosa protection. However, its inherent poor aqueous solubility and strong irritation impede the further clinical application. In our study, acyclic cucurbit[n]urils (ACBs, M1, M2 and M3) were rationally utilized to prepare a series of CAP inclusion complexes to improve the bioavailability and reduce stimulation. Their properties and inclusion behaviors were further investigated by multiple characterization methods, the data indicated that the inclusion complexes of ACBs/CAP were formed by a stoichiometric ratio of 2:1 with strong binding interaction. After complexation, the solubility of CAP was significantly increased by 12,076 times and its antioxidant activity also increased. Moreover, the anti-inflammatory activity and the ability to prevent gastric mucosal injury were both significantly improved, and the inhibition rate of nitric oxide (NO) and interleukin-1β (IL-1β) has been effectively improved while cytotoxicity against human normal hepatocytes cell (LO2), human lung fibroblasts cell (HLF) and the human gastric mucosal cell (GES-1) was greatly attenuated. Confocal laser scanning microscope (CLSM) images indicated that the complexes could be efficiently internalized by GES-1 cells and primarily located in cytoplasm. In vivo model of mouse, our complexes exhibited excellent biosafety. In summary, our study may provide a promising new strategy for the further clinical application of CAP.

Abstract
As a common disease of the digestive system, chronic gastritis is inflammation of the gastric mucosa caused by various factors. Helicobacter pylori (H. pylori) is one of the main causes of chronic gastritis, which can lead to gastric mucosal damage and gland atrophy, thereby promoting gastrocarcinogenesis. Oxidative stress and the inflammatory response are important mechanisms of H. pylori-induced gastritis. 6'-O-Galloylpaeoniflorin (GPF) is a substance isolated from peony root with antioxidant and anti-inflammatory activities. However, its role and mechanism in the pathogenesis of H. pylori-induced chronic gastritis remain unclear. This study explored the effects of GPF on H. pylori-induced gastric mucosal oxidative stress and inflammation using flow cytometry, western blotting, real-time quantitative PCR, and immunohistochemistry. We found that H. pylori infection increased oxidative stress and expression of inflammatory cytokines in vitro and in vivo and that these outcomes were inhibited by GPF. Furthermore, GPF activated nuclear factor erythroid-related factor-2 (Nrf2) and its downstream target genes in H. pylori-infected GES-1 cells and mice. The anti-inflammatory and antioxidant effects of GPF on H. pylori-infected cells were attenuated by an Nrf2 inhibitor. Taken together, these data suggest that GPF reduces H. pylori-induced gastric mucosa injury by activating Nrf2 signaling and that GPF is a potential candidate for the treatment of H. pylori-associated gastritis.

Front Pharmacol 2022; 13:898680. [PMID: 35899115 PMCID: PMC9310101 DOI: 10.3389/fphar.2022.898680] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2022] [Accepted: 06/03/2022] [Indexed: 11/13/2022] Open
Abstract
Objective: Chronic nonatrophic gastritis (CNG) is the most common digestive disease. In China, Zuojin pill (ZJP) is considered an effective medicine formula for CNG. However, its efficacy and mechanism have never been explored. In order to understand how and why ZJP demonstrates therapeutic effect on CNG, a clinical trial was conducted. Metabolomics was used to explore its deep mechanism. Methods: A total of 14 patients with CNG were recruited from October 2020 to March 2021 (ChiCTR2000040549). The endoscopy and histopathological changes were evaluated as efficacy. Serum samples were prepared and detected by performing widely targeted metabolome using UPLC. Multivariate statistical analysis was conducted to identify potential differential metabolites and signaling pathways. Last, the signal-related inflammatory factors containing COX-2, IL-4, and IL-17 were confirmed via immunohistochemical staining and enzyme-linked immunosorbent assay. Results: ZJP was able to alleviate several indexes of mucosal injury under endoscopy and histology. Erosion and bile reflux, but not red plaques and hemorrhage, were downregulated by ZJP. In addition, it could remarkably alleviate active chronic inflammation. A total of 14 potential metabolites, namely, hypoxanthine, adipic acid, D-ribono-1,4-lactone, L-sepiapterin, imidazoleacetic acid, sebacate, ADP-ribose, 4-hydroxybenzyl alcohol, 11,12-EET, 15-OxoETE, 12-OxoETE, (±)8-HETE, glycyrrhizinate, and DL-aminopimelic acid, were discriminated by metabolomics. Moreover, certain amino acid metabolism got significance during the disease progress and treatment. The related inflammatory factors including COX-2, IL-4, and IL-17 were inhibited by ZJP in both mucosa and serum. Conclusion: All these results indicated that ZJP partially acts as an inflammatory suppressor to regulate comprehensive metabolism disorders. This might be an important mechanism of ZJP in the treatment of CNG.

Abstract
The oral administration of a single formulation loaded with more than one natural medicine to treat chronic diseases has advantages such as convenience, effectiveness, and economy. Here, using biomaterials approved by the drug administration, we fabricated supramolecular nanovectors containing dual natural medicines to prevent gastric mucosal lesions. Nanovectors exhibited superior intestinal absorption and bioavailability, which might be due to their high dispersion, good muco-adhesiveness, blood-lymph circulation transport, lipid sensing, and protective effects. Molecular docking results clarified the possible mechanisms in aspects of efflux pump (p-glycoprotein and multidrug resistance protein 1) inhibition effects, metabolic enzyme (cytochrome P450 3A4/1A2) blocking effects, serum albumin deposit effects, and dual drug interaction effects. Nanovectors decreased ethanol-induced gastric mucosal lesions by lowering the gastric ulcer index, preventing oxidative damage, decreasing interleukin-6, tumor necrosis factor-α and malondialdehyde, increasing glutathione, superoxide dismutase, and prostaglandin E2 levels. The interactions of inhibitor of nuclear factor-κB or κB kinase-related proteins and dual drugs or nanovector components were simulated computationally to provide an understanding of the gastro-protective action mechanism. In all, industrializable supramolecular nanovectors could effectively co-deliver dual natural medicines via the oral route by improving the pharmacokinetic behavior and exerting protective efficacy of the gastric mucosa by decreasing the oxidative stress and inflammatory level.

Abstract
The present study was conducted to investigate the protective action of Salvia officinalis flowers aqueous extract (SOFAE) against combined gastro-intestinal (GI) disorders-induced by ethanol and castor oil administration in rats. Adult male Wistar rats were divided into seven groups of ten each and various doses of SOFAE (50, 100, and 200 mg kg−1, b.w., p.o.) and sulfasalazine (100 mg kg−1, b.w., p.o.) were daily administrated during 15 days. After, animals were intoxicated with a single oral administration of ethanol (4 g kg−1, b.w., p. o.) and castor oil (5 mL kg−1, b.w., p.o.). We found that SOFAE contains several phytoactive compounds with a strong ABTS scavenging ability. In vivo, we showed that SOFAE protected against EtOH/CO-induced macroscopic and histological alterations in GI tract accompanied by intestinal fluid accumulation and gastric juice decrease. SOFAE significantly counteracted lipoperoxydation increase and reversed the depletion of both enzymatic and non-enzymatic antioxidants. More importantly, SOFAE significantly reduced the levels of inflammatory markers (CRP and ALP) in plasma and mucosal GI tract. In conclusion, our data clearly indicate that the SOFAE exerted a potential protective effect against EtOH-induced peptic ulcer combined with CO-induced diarrhea in rats. These effects could be associated with its antioxidant and anti-inflammatory properties.

Efficacy and Safety of Zuojin Pill for the Treatment of Chronic Nonatrophic Gastritis: A Randomized Active-Controlled Clinical Trial. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2022; 2022:2266023. [PMID: 35432566 PMCID: PMC9010182 DOI: 10.1155/2022/2266023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/03/2022] [Accepted: 03/25/2022] [Indexed: 11/17/2022]
Abstract
Objective Zuojin pill (ZJP) is used as the classical prescription for a wide variety of digestive diseases. However, there is a lack of direct evidence for its use in the treatment of chronic nonatrophic gastritis (CNG). In particular, there is a lack of rigorous trials of randomized controlled designs. In this study, a randomized active-controlled clinical trial was performed to verify the efficacy and safety of ZJP in detail. Methods Patients with CNG were divided into the ZJP group and the Marzulene-S granule group. Patients were enrolled from September 2019 to February 2021 (ChiCTR2000040549). Endoscopy and histology scores were evaluated as the primary outcome measure. The Helicobacter pylori positive rate and the disappearance rate of symptoms were also measured to reflect the outcomes. Finally, adverse events were also calculated as the index of safety. Results A total of 68 eligible patients were enrolled in this trial and randomly divided into two groups with baseline comparability. ZJP was able to improve the red plaques as well as bile reflux scores compared with Marzulene-S granule (P=0.043 and P=0.019, respectively). Moreover, it also remarkably alleviated the active chronic inflammation score (P=0.043). However, there was no difference between the Helicobacter pylori positivity rate (P=0.752). The symptom scores of abdominal distension (P=0.004), belching (P=0.010), and loss of appetite (P=0.019) were alleviated by ZJP, but nausea and vomiting were not (P=0.616). ZJP can also be considered safe with no obvious adverse effects. Conclusion ZJP might decrease mucosal injury and alleviate symptoms in CNG. In addition, more large-scale clinical trials should be carried out to further confirm its clinical efficacy and safety.

Abstract
Rutaecarpine (RUT) is an alkaloid isolated from Tetradium ruticarpum, which has been reported to protect against several inflammatory diseases. However, to the best of our knowledge, the role of RUT in acute lung injury (ALI) and the specific molecular mechanism remain unknown. In the present study, an in vitro model of ALI was established in BEAS-2B cells by lipopolysaccharide (LPS) administration. Cell viability following RUT treatment with or without LPS stimulation was evaluated using a Cell Counting Kit-8 assay. The inflammatory response and oxidative stress were detected using ELISA kits and commercially available kits, respectively. TUNEL assay and western blotting were performed to assess cell apoptosis. The expression levels of endoplasmic reticulum (ER) stress-related proteins and AMP-activated protein kinase (AMPK)/sirtuin 1 (SIRT1) signaling pathway-related proteins were measured by western blotting. The results revealed that RUT markedly improved cell viability after LPS treatment in a dose-dependent manner. In addition, RUT inhibited the LPS-induced inflammatory response and oxidative stress in BEAS-2B cells, and suppressed the LPS-induced apoptosis of BEAS-2B cells. Mechanistically, RUT alleviated ER stress by inhibiting the production of CHOP, glucose-regulated protein-78, caspase-12 and activating transcription factor 6. Additionally, western blotting demonstrated that RUT activated the phosphorylation of AMPK and SIRT1, which indicated the involvement of the AMPK/SIRT1 signaling pathway in the protective effect of RUT against LPS-induced lung injury. In conclusion, these results demonstrated that RUT mitigated LPS-induced lung cell injury by inhibiting ER stress via the activation of the AMPK/SIRT1 signaling pathway.

JOURNAL OF ETHNOPHARMACOLOGY 2022; 285:114855. [PMID: 34808298 DOI: 10.1016/j.jep.2021.114855] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/29/2021] [Revised: 11/05/2021] [Accepted: 11/17/2021] [Indexed: 06/13/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Zuojin pill (ZJP), a classical Chinese medicine formula, has been widely applied in Chinese clinical practice for the treatment of gastric injury such as acute gastric lesion, acute gastric mucosal injury, chronic unpredictable mild stress, gastroesophageal reflux disease, etc, thereby exerting anti-chronic atrophic gastritis (CAG) effects in traditional Chinese herbal medicine. AIM OF THE STUDY This study was aimed to explore the therapeutic effects and molecular mechanisms of ZJP on Helicobacter pylori (H. pylori)-induced CAG based on the comprehensive approaches. MATERIALS AND METHODS Sprague-Dawley rats were infected with H. pylori for 8 weeks to establish CAG model. Then, rats in the ZJP groups received doses of 0.63, 1.26, and 2.52 g/kg ZJP for 4 weeks. Therapeutic effects of ZJP on serum indices and the histopathology of the gastric were analyzed in vivo. Moreover, GES-1 cells were infected with H. pylori to establish gastric epithelial cell injury model in vitro. Cell viability and gastric epithelial cell morphology were detected by a high-content screening (HCS) assay. Furthermore, the relative mRNA and protein expression of JMJD2B/COX-2/VEGF axis and HMGB1/NF-κB signaling pathway in vivo and in vitro were determined by RT-PCR and Western Blotting, respectively. RESULTS The results showed that the therapeutic effects of ZJP on CAG rats were presented in down-regulation serum biochemical indices and alleviating histological damage of gastric tissue. ZJP could dose-dependently decrease the serum IL-6, MCP-1, PGE2, TNF-α, and VEGF level and significantly improved gastric tissue inflammatory lesions. Besides, ZJP has an effect on increasing cell proliferation of GES-1 cells, ameliorating H. pylori-induced gastric epithelial cell damage. It was found that ZJP has a down-regulating effect on inflammatory reaction and could inhibit the relative mRNA and protein expression of JMJD2B/COX-2/VEGF axis and HMGB1/NF-κB signaling pathway in vivo and in vitro, including JMJD2B, COX-2, VEGF, VEGFR1, and VEGFR2, which in turn reduced the damage of gastric mucosal cells. CONCLUSIONS The results suggested that ZJP exerts therapeutic effects on H. pylori-induced CAG by inhibiting the JMJD2B/COX-2/VEGF axis and HMGB1/NF-κB signaling pathway. These findings deeply explained why ZJP could be used to treat CAG clinically and clarified its pharmacological effect and potential mechanism in the treatment of CAG.

Network Pharmacology and Molecular Docking Analysis on Pharmacological Mechanisms of Astragalus membranaceus in the Treatment of Gastric Ulcer. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2022; 2022:9007396. [PMID: 35140802 PMCID: PMC8820867 DOI: 10.1155/2022/9007396] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/09/2021] [Revised: 12/09/2021] [Accepted: 01/12/2022] [Indexed: 12/18/2022]
Abstract
BACKGROUND Astragalus membranaceus (AM, family: Leguminosae) exerts significant therapeutic effect on gastric ulcer (GU); however, there are scarce studies on its molecular mechanism against GU. This study aims to explore the key ingredients, key targets, and potential mechanisms of AM in the treatment of GU by utilizing network pharmacology and molecular docking. METHODS Several public databases were used to predict the targets of AM and GU, respectively, and the drug and disease targets were intersected to obtain the common targets. Next, the key ingredients and key targets were identified by constructing ingredient-target network and protein-protein-interaction (PPI) network. Gene Ontology biological processes (GOBP) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis were carried out on the common targets in order to ascertain the biological processes and signaling pathways involved. Finally, molecular docking was conducted to verify the binding affinity between the key ingredients and key targets. RESULTS A total of 552 predicted targets were obtained from 23 screened active ingredients, of which 203 targets were the common targets with GU. Quercetin, kaempferol, and isorhamnetin were identified as the key ingredients by constructing ingredient-target network, and TP53, AKT1, VEGFA, IL6, TNF, CASP3, and EGFR were selected as the key targets by constructing PPI network. GOBP and KEGG pathway enrichment analysis suggested that the therapeutic effect of AM on GU involved multiple biological processes and signaling pathways related to inflammation, oxidative stress, apoptosis, cell proliferation, and angiogenesis. Molecular docking validation demonstrated that all key ingredients had good binding affinity with the key targets. CONCLUSION This study revealed the key ingredients, key targets, and potential mechanisms of AM against GU, and these data may provide some crucial references for subsequent research and development of drugs for treating GU.

Extract Against Ethanol-Induced Gastric Ulcer in Mice by Suppressing Apoptosis-Related Pathways. Front Pharmacol 2022; 12:798421.

Abstract
Although Periplaneta americana L. and its modern preparation, Kangfuxin liquid, have been extensively applied for ulcerative diseases in gastrointestinal tract (e.g., gastric ulcer (GU) and ulcerative colitis, the effective components and potential mechanisms) remain unclear. In accordance with the accumulating research evidences, the relieving/exacerbating of GU is noticeably correlated to focal tissue programmed cell death. Herein, gastro-protective effects of the effective Periplaneta americana L. extract (PAE) fraction were assessed in vitro and in vivo, involving in programmed cell death-related signaling channels. To screen the effective PAE fraction exerting gastroprotective effects, several PAE fractions were gained based on a wide range of ethanol solution concentration, and they were assessed on ethanol-induced ulcer mice. Based on HPLC investigation with the use of nucleosides, the chemical composition of screened effective PAE, extracted by 20% ethanol, was analyzed in terms of quality control. Based on CCK-8 assay, the protective effects on GES-1 cells, impaired by ethanol, of PAE were assessed. After 3 days pre-treatment with PAE (200, 400, 800 mg/kg), the gastric lesions were assessed by tissue morphology, and periodic acid-schiff (PAS) staining, as well as hematoxylin and eosin (H&E) based histopathology-related investigation. The levels for inflammation cytokines (IL1-β, TNF-α, IL-18, PGE2, and IL-6), antioxidant indices (SOD and MDA) were examined via ELISA. In the meantime, based on Western Blotting assay, the expression levels of some programmed cell death-related protein targets (NLRP3, caspase-1, NF-κB p65, MyD88, and TLR4) were analyzed. As revealed from the results, PAE is capable of alleviating gastric mucosa impairment, suppressing the inflammatory cytokines, and down-regulating the MyD88/NF-κB channels. Accordingly, 20% ethanol extract of Periplaneta americana L. would contribute its gastroprotective effects, thereby providing the evidence that its anti-GU mechanisms correlated with inhibiting programmed cell death channel.

Abstract
Acute gastric injury caused by ethanol is a frequent disorder of the gastrointestinal tract. In this study, we investigated the potential gastroprotective effects of Tricholoma matsutake-derived peptides against ethanol-triggered acute gastric injury and the associated mechanisms. Peptides SDLKHFPF and SDIKHFPF significantly attenuated the ethanol-induced decrease in GES-1 cell survival (82.39 ± 1.93 and 80.10 ± 1.08% vs 56.58 ± 1.86%), inhibited GES-1 cell apoptosis, and alleviated the ethanol-induced gastric mucosal injury (64.76 ± 3.98 and 49.29 ± 3.25%), ulcer index (3.33 ± 0.47 and 4.67 ± 0.47 vs 6.67 ± 0.47), and histopathological changes in mice. Peptide treatment inhibited the phosphorylation and nuclear translocation of nuclear factor kappa B (NF-κB), the secretion of tumor necrosis factor-α, interleukin-6, and endothelin-1. In addition, T. matsutake peptide pretreatment increased growth factor secretion, upregulated B-cell lymphoma-2, downregulated Bcl-2-associated X (Bax), and cleaved cysteinyl aspartate specific proteinase 3, thereby promoting gastric cell survival. These findings strongly suggest that T. matsutake peptides attenuate ethanol-induced inflammatory responses and apoptosis by suppressing NF-κB signaling activation, thereby enhancing gastric epithelial barrier functions.

Abstract
In this study, deer suet fat was used as a raw material to study the effects of aqueous enzymatic extraction of deer oil on its components, followed by studies into the potential protective activity, and related molecular mechanisms of deer oil on ethanol-induced acute gastric mucosal injury in rats. The results show that aqueous enzymatic extraction of deer oil not only has a high extraction yield and has a small effect on the content of active ingredients. Deer oil can reduce total stomach injury. Without affecting the blood lipid level, it can reduce the oxidative stress, which is manifested by reducing the content of myeloperoxidase (MPO) and enhancing the activity level of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px). It also enhances the expression of defense factors prostaglandin (E2), epidermal growth factor (EGF), and somatostatin (SS), it inhibits apoptosis evidenced by the enhanced of Bcl-2 and decreased expression of cleavage of caspase-3 and Bax. At the same time, it reduces inflammation, which is manifested by reducing the expression of IL-1β, interleukin 6 (IL-6), and tumor necrosis factor alpha (TNF-α) gastric tissue pro-inflammatory cytokines, and enhancing the expression of anti-inflammatory factors IL-4 and IL-10, and inhibiting the mitogen-activated protein kinase/nuclear factor kappa B (MAPK/NF-κB) signaling pathway in gastric tissue.

The Gastroprotective Effect of Naringenin against Ethanol-Induced Gastric Ulcers in Mice through Inhibiting Oxidative and Inflammatory Responses. Int J Mol Sci 2021; 22:ijms222111985. [PMID: 34769415 PMCID: PMC8584376 DOI: 10.3390/ijms222111985] [Citation(s) in RCA: 20] [Impact Index Per Article: 6.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2021] [Revised: 10/29/2021] [Accepted: 11/03/2021] [Indexed: 01/28/2023] Open
Abstract
Naringenin is a major flavanone found in grapes, tangelos, blood oranges, lemons, pummelo, and tangerines. It is known to have anti-inflammatory, antioxidant, anticancer, antimutagenic, antifibrogenic, and antiatherogenic pharmacological properties. This study aims to investigate the anti-inflammatory effects of naringenin in ethanol-induced gastric damage in vivo and ethanol-stimulated KATO III cells in vitro. Our results showed that pretreatment with naringenin significantly protected mice from ethanol-induced hemorrhagic damage, epithelial cell loss, and edema with leucocytes. It reduced gastric ulcers (GU) by suppressing ethanol-induced nuclear factor-κB (NF-κB) activity and decreasing the levels of nitric oxide (NO), malondialdehyde (MDA), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), interleukin-8 (IL-8), and myeloperoxidase (MPO). In addition, pretreatment with naringenin might inhibit the secretion of TNF-α, IL-6, and IL-8, as well as the proteins cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS) via the suppression of NF-κB and mitogen-activated protein kinase (MAPK) signaling in ethanol-stimulated stomach epithelial KATO III cells. Together, the results of this study highlight the gastroprotective effect of naringenin in GU of mice by inhibiting gastric secretion and acidity, reducing inflammation and oxidative stress, suppressing NF-κB activity, and restoring the histological architecture. These findings suggested that naringenin has therapeutic potential in the alleviation of ethanol-induced GU.

Sesamin Protects against and Ameliorates Rat Intestinal Ischemia/Reperfusion Injury with Involvement of Activating Nrf2/HO-1/NQO1 Signaling Pathway. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2021; 2021:5147069. [PMID: 34630849 PMCID: PMC8494576 DOI: 10.1155/2021/5147069] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/07/2021] [Revised: 08/06/2021] [Accepted: 08/11/2021] [Indexed: 02/06/2023]
Abstract
Intestinal ischemia-reperfusion (I/R) may induce cell/tissue injuries, leading to multiple organ failure. Based on our preexperiments, we proposed that sesamin could protect against and ameliorate intestinal I/R injuries and related disorders with involvement of activating Nrf2 signaling pathway. This proposal was evaluated using SD intestinal I/R injury rats in vivo and hypoxia/reoxygenation- (H/R-) injured rat small intestinal crypt epithelial cell line (IEC-6 cells) in vitro. Sesamin significantly alleviated I/R-induced intestinal histopathological injuries and significantly reduced serum biochemical indicators ALT and AST, alleviating I/R-induced intestinal injury in rats. Sesamin also significantly reversed I/R-increased TNF-α, IL-6, IL-1β, and MPO activity in serum and MDA in tissues and I/R-decreased GSH in tissues and SOD in both tissues and IEC-6 cells, indicating its anti-inflammatory and antioxidative stress effects. Further, sesamin significantly decreased TUNEL-positive cells, downregulated the increased Bax and caspase-3 protein expression, upregulated the decreased protein expression of Bcl-2 in I/R-injured intestinal tissues, and significantly reversed H/R-reduced IEC-6 cell viability as well as reduced the number of apoptotic cells among H/R-injured IEC-6 cell, showing antiapoptotic effects. Activation of Nrf2 is known to ameliorate tissue/cell injuries. Consistent with sesamin-induced ameliorations of both intestinal I/R injuries and H/R injuries, transfection of Nrf2 cDNA significantly upregulated the expression of Nrf2, HO-1, and NQO1, respectively. On the contrary, either Nrf2 inhibitor (ML385) or Nrf2 siRNA transfection significantly decreased the expression of these proteins. Our results suggest that activation of the Nrf2/HO-1/NQO1 signaling pathway is involved in sesamin-induced anti-inflammatory, antioxidative, and antiapoptotic effects in protection against and amelioration of intestinal I/R injuries.

Identification of evodiamine and rutecarpine as novel TMEM16A inhibitors and their inhibitory effects on peristalsis in isolated Guinea-pig ileum. Eur J Pharmacol 2021; 908:174340. [PMID: 34265294 DOI: 10.1016/j.ejphar.2021.174340] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2021] [Revised: 06/29/2021] [Accepted: 07/11/2021] [Indexed: 12/22/2022]
Abstract
The transmembrane member 16A (TMEM16A)-encoded Ca2+-activated Cl- channel (CaCC) is expressed in interstitial cells of Cajal (ICCs) and involved in the generation of the slow-wave currents of gastrointestinal (GI) smooth muscles. TMEM16A modulators have been shown to positively or negatively regulate the contraction of gastrointestinal smooth muscle. Therefore, targeting the pharmacological modulation of TMEM16A may represent a novel treatment approach for gastrointestinal dysfunctions such as constipation and diarrhoea. In this study, evodiamine and rutecarpine were extracted from the traditional Chinese medicine Evodia rutaecarpa and identified as novel TMEM16A inhibitors with comparable inhibitory effects. Their effects on intestinal peristalsis were examined. Whole-cell patch clamp results show that evodiamine and rutecarpine inhibited TMEM16A Cl- currents in CHO cells. The half-maximal inhibition values (IC50) of evodiamine and rutecarpine on TMEM16A Cl- currents were 11.8 ± 1.3 μΜ and 9.2 ± 0.4 μM, and the maximal effect values (Emax) were 95.8 ± 5.1% and 99.1 ± 1.6%, respectively. The Lys384, Thr385, and Met524 in TMEM16A are critical for evodiamine and rutecarpine's inhibitory effects. Further functional studies show that both evodiamine and rutecarpine can significantly suppress the peristalsis in isolated guinea-pig ileum. These findings demonstrate that evodiamine and rutecarpine are new TMEM16A inhibitors and support the regulation effect of TMEM16A modulators on gastrointestinal motility.

Agarwood Alcohol Extract Protects against Gastric Ulcer by Inhibiting Oxidation and Inflammation. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2021; 2021:9944685. [PMID: 34580595 PMCID: PMC8464430 DOI: 10.1155/2021/9944685] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/24/2021] [Revised: 08/20/2021] [Accepted: 08/23/2021] [Indexed: 11/30/2022]
Abstract
Background Agarwood has been used for centuries, especially for treatment of gastrointestinal diseases. Earlier studies of our laboratory suggested that agarwood alcohol extracts (AAEs) provided gastric mucosal protection. This study aims to investigate the ameliorative effect of AAEs on ethanol-induced gastric ulcers and its mechanism. Methods Mice were given agarwood induced by the whole-tree agarwood-inducing technique alcohol extract (WTAAE, 0.71, 1.42, and 2.84 g/kg), wild agarwood induced by axe wounds alcohol extract (WAAE, 2.84 g/kg), and burning-chisel-drilling agarwood alcohol extract (FBAAE, 2.84 g/kg) orally, respectively. After 7 days' pretreatment with AAEs, the gastric ulcers were induced by absolute ethanol. The ulcer index, gastric histopathology, biochemical parameters, and inflammatory proteins were evaluated. Results Pharmacological results showed AAEs (1.42 and 2.84 g/kg) reduced the gastric occurrence and ulcer inhibition rates up to more than 60%. AAEs decreased the level of nitric oxide (NO) and increased glutathione (GSH) and superoxide dismutase (SOD) levels. Besides, AAEs decreased the levels of interleukin-1β (IL-1β) and interleukin-6 (IL-6), but the interleukin-10 (IL-10) was upregulated. The expressions of nuclear factor kappa B (NF-κB) and phosphorylated protein 38 (p-P38) were inhibited. The effect of WTAAE was better than that of FBAAE and similar to that of WAAE at the dose of 2.84 g/kg. Conclusions These results demonstrate that agarwood alleviates the occurrence and development of gastric ulcers via inhibiting oxidation and inflammation.

Syzygium samarangense leaf extract mitigates indomethacin-induced gastropathy via the NF-κB signaling pathway in rats. Biomed Pharmacother 2021; 139:111675. [PMID: 33965725 DOI: 10.1016/j.biopha.2021.111675] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2021] [Revised: 04/23/2021] [Accepted: 04/26/2021] [Indexed: 12/24/2022] Open
Abstract
We previously profiled the chemical composition of wax apple, Syzygium samarangense, leaf extract using HR-LC-MS/MS and reported its antioxidant, hepatoprotective and antitrypanosomal activities. The plant is widely used in traditional medicine to cure several ailments like bronchitis, asthma, diabetes, fever, pathogenic infections, gut spasms, as well as renal diseases. However, neither the gastroprotective effects nor the underlying mechanisms were explored. Here, we investigated the gastroprotective potential of the leaf extract on indomethacin-induced gastric ulcer in rats and explored the involved mechanism(s) of action. Administration of indomethacin significantly increased the ulcer index, mucosal injury, the gastric levels of the inflammatory markers nuclear factor kabba B-p65(NF-κB p65), myeloperoxidase (MPO), interleukin-6 (IL-6), tumor necrosis factor alpha (TNF-α), lipid peroxidation product, malondialdehyde (MDA) and Caspase-3 expression. It reduced the gastric levels of the endogenous antioxidants glutathione as well peroxidase (GPx), reduced glutathione (GSH) and the gastric mucosal protective factors, mucus secretion and goblet cells. Pretreatment with the leaf extract displayed a prominent decrease in the ulcer index, inflammatory cell infiltration, inflammatory markers, MDA, protein expression of Caspase-3 and a significant increase in the gastric levels of the endogenous antioxidants, mucus content and goblet cell proliferation when compared to the indomethacin group. The individual secondary metabolites of the extract exhibited low binding energy when docked into the prostaglandin receptors EP3 and EP4. This study revealed the gastroprotective effect of S. samarangense on indomethacin-induced gastric ulcer in rats. The gastroprotective effects might be attributed to cytoprotective, antioxidant, anti-inflammatory and antiapoptotic activities with a possible potential of activating EP3 and EP4 receptors. In conclusion, S. samarangense has a promising potential in the prevention of NSAIDs-induced ulcers.

Mechanism of rutaecarpine on ethanol-induced acute gastric ulcer using integrated metabolomics and network pharmacology. Biomed Pharmacother 2021; 138:111490. [PMID: 33773465 DOI: 10.1016/j.biopha.2021.111490] [Citation(s) in RCA: 20] [Impact Index Per Article: 6.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2021] [Revised: 02/22/2021] [Accepted: 03/09/2021] [Indexed: 11/15/2022] Open
Abstract
This study was aimed to explore the mechanism of rutaecarpine (RUT) on ethanol-induced gastric ulcer (GU) in mice by integrated approaches. At first, the efficacy was determined through the macroscopic and microscopic state of stomach tissue and the expression levels of GU-related factors. Then, the serum metabolomics method based on UPLC-Q-TOF/MS was used to explore the specific metabolites and metabolic pathways. Finally, the upstream key protein targets of these specific metabolites were analyzed by network pharmacology and verified by PCR to explore the potential mechanism. RUT alleviated the histological and pathological damage of gastric tissue caused by ethanol, and could remarkably ameliorate the level of GU-related factors. Subsequently, a total of 7 potential metabolites involved in 9 metabolic pathways were identified by metabolomics analysis. Then, a 'component-targets-metabolites' interaction network was constructed, and therefore 4 key target proteins (PLA2G1B, PDE5A, MIF and SRC) that may regulate the specific metabolites were obtained. This case was further verified by the results of PCR. ALL the above results strongly demonstrated that RUT exerted a gastroprotective effect against GU. And it is the first time to combine metabolomics combined with network pharmacology to elucidate the mechanism of RUT on GU, which may be related to the regulation of energy metabolism, oxidative stress, and inflammation, and these pathways may be regulated through the upstream protein PLA2G1B, PDE5A, MIF and SRC.
