Novel applications of Yinhua Miyanling tablets in ulcerative colitis treatment based on metabolomics and network pharmacology. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2024; 128:155366. [PMID: 38537445 DOI: 10.1016/j.phymed.2024.155366] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/19/2023] [Revised: 12/13/2023] [Accepted: 01/14/2024] [Indexed: 05/01/2024]
Abstract
BACKGROUND Yinhua Miyanling tablets (YMT), comprising 10 Chinese medicinal compounds, is a proprietary Chinese medicine used in the clinical treatment of urinary tract infections. Medicinal compounds, extracts, or certain monomeric components in YMT all show good effect on ulcerative colitis (UC). However, no evidence supporting YMT as a whole prescription for UC treatment is available. PURPOSE To evaluate the anti-UC activity of YMT and elucidate the underlying mechanisms. The objective of the study was to provide evidence for the add-on development of YMT to treat UC. METHODS First, YMT's protective effect on the intestinal barrier was evaluated using a lipopolysaccharide (LPS)-induced Caco-2 intestinal injury model. Second, the UC mouse model was established using dextran sodium sulfate (DSS) to determine YMT's influence on symptoms, inflammatory factors, intestinal barrier, and histopathological changes in the colon. Third, an integrated method combining metabolomics and network pharmacology was employed to screen core targets and key metabolic pathways with crucial roles in YMT's therapeutic effect on UC. Molecular docking was employed to identify the key targets with high affinity. Finally, western blotting was performed to validate the mechanism of YMT action against UC. RESULTS YMT enhanced the transepithelial electrical resistance value and improved the expression of proteins of the tight junctions dose-dependently in LPS-induced Caco-2 cells. UC mice treated with YMT exhibited alleviated pathological lesions of the colon tissue in the in vivo pharmacodynamic experiments. The colonic lengths tended to be normal, and the levels of inflammatory factors (TNF-α, IL-6, and iNOS) along with those of the core enzymes (MPO, MDA, and SOD) improved. YMT effectively ameliorated DSS-induced colonic mucosal injury; pathological changes along with ultrastructure damage were significantly alleviated (evidenced by a relatively intact colon tissue, recovery of epithelial damage, repaired gland, reduced infiltration of inflammatory cells and epithelial cells arranged closely with dense microvilli). Seven key targets (IL-6, TNF-α, MPO, COX-2, HK2, TPH, and CYP1A2) and four key metabolic pathways (arachidonic acid metabolism, linoleate metabolism, glycolysis, and gluconeogenesis and tyrosine biosynthesis) were identified to play vital roles in the treatment on UC using YMT. CONCLUSIONS YMT exerts beneficial therapeutic effects on UC by regulating multiple endogenous metabolites, targets, and metabolic pathways, suggestive of its potential novel application in UC treatment.

Development and Validation of a High-Performance Liquid Chromatography Method to Quantify Marker Compounds in Lysimachia vulgaris var. davurica and Its Effects in Diarrhea-Predominant Irritable Bowel Syndrome. Molecules 2024; 29:1489.

Abstract
Irritable bowel syndrome (IBS), a common gastrointestinal disorder worldwide, is characterized by chronic abdominal pain, bloating, and disordered defecation. IBS is associated with several factors, including visceral hypersensitivity, gut motility, and gut-brain interaction disorders. Because currently available pharmacological treatments cannot adequately improve symptoms and may cause adverse effects, the use of herbal therapies for managing IBS is increasing. Lysimachia vulgaris var. davurica (LV) is a medicinal plant used in traditional medicine to treat diarrhea. However, information on whether LV can effectively improve diarrhea-predominant IBS (IBS-D) remains limited. In this study, using an experimental mouse model of IBS-D, we elucidated the effects of the LV extract. The methanol extract of LV decreased fecal pellet output in the restraint stress- or 5-hydroxytryptamine (5-HT)-induced IBS mouse model and inhibited 5-HT-mediated [Ca2+]i increase in a dose-dependent manner. Furthermore, we developed and validated a high-performance liquid chromatography method using two marker compounds, namely, chlorogenic acid and rutin, for quality control analysis. Our study results suggest the feasibility of the methanol extract of LV for developing therapeutic agents to treat IBS-D by acting as a 5-HT3 receptor antagonist.

MEDICINA (KAUNAS, LITHUANIA) 2023; 59:1990. [PMID: 38004039 PMCID: PMC10673539 DOI: 10.3390/medicina59111990] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/14/2023] [Revised: 10/29/2023] [Accepted: 11/01/2023] [Indexed: 11/26/2023]
Abstract
Background and Objectives: Urtica dioica, a source of bioactive functional compounds, provides nutritional and gastrointestinal therapeutic benefits. This study attempted to investigate the prophylactic coloprotective action of an aqueous extract of Urtica dioica (AEUD) on dextran sulfate sodium (DSS)-induced ulcerative colitis (UC). Materials and Methods: Phenolic compounds, total sugar, and mineral levels were determined in AEUD. Then, AEUD at different doses (50, 100, and 200 mg/kg, BW, p.o.) and mesalazine (MESA) as a standard treatment (100 mg/kg, BW, p.o.) were given orally for 21 days. Acute colitis was induced by administering drinking water with 5% (w/v) DSS for 7 days. Body weight variation, fecal occult blood, and stool consistency were determined daily. The severity of colitis was graded according to colon length, disease activity index (DAI), histological evaluations, and biochemical alterations. Rats orally administered DSS regularly developed clinical and macroscopic signs of colitis. Results: Due to its richness in phenolic and flavonoid compounds (247.65 ± 2.69 mg EAG/g MS and 34.08 ± 0.53 mg EQt/g MS, respectively), AEUD markedly ameliorated DAI, ulcer scores, colon length shortening, colonic histopathological changes, and hematological and biochemical modifications. Taken together, AEUD treatment notably (p < 0.01) suppressed DSS-induced UC by reducing oxidative stress via lowering MDA/H2O2 production and stimulating the effect of enzyme antioxidants as well as attenuating inflammation by decreasing CRP levels by 79.5% between the DSS and DSS + AEUD-50 groups compared to the MESA group (75.6%). Conclusions: AEUD was sufficient to exert a coloprotective effect that might be influenced by its bioactive compounds' anti-inflammatory and antioxidant capabilities.

Abstract
The rising incidence of inflammatory bowel disease (IBD) has necessitated the search for safe and effective novel therapeutic strategies. Dietary flavonoids exhibited antioxidant, antiproliferative, and anticarcinogenic activities in several model systems with proven abilities to reduce inflammation and oxidative stress, thus they could be promising therapeutic agents for IBD prevention/treatment. However, understanding the role of a specific class of compounds in foods that promote health is difficult because of the chemically complex food matrices. This study aimed to utilize four maize near-isogenic lines to determine the anti-colitis effects of specific classes of flavonoids, anthocyanins and/or phlobaphenes, in a whole-food matrix. Results showed that the intake of anthocyanin and phlobaphene-enriched maize diets effectively alleviated dextran sodium sulfate (DSS)-induced colitis in mice via reducing the intestinal permeability and restoring the barrier function. Anthocyanin diets were more effective in maintaining the crypt structure and muc2 protein levels and reducing inflammation. Bacterial communities of mice consuming diets enriched with anthocyanins and phlobaphenes were more similar to the healthy control compared to the DSS control group, suggesting the role of flavonoids in modulating the gut microbiota to retrieve intestinal homeostasis. Microbiota depletion rendered these compounds ineffective against colitis. Lower serum concentrations of several phenolic acids were detected in the microbiota-depleted mice, indicating that gut microbiota plays a role in flavonoid metabolism and bioavailability.

J Adv Res 2023; 52:73-88.

Abstract
INTRODUCTION Dietary fiber and flavonoids are promising drugs reported in the treatment of inflammatory bowel disease (IBD). However, it is unclear the interaction between dietary fiber and flavonoids in gut health. OBJECTIVE The therapeutic effect of celery, kale, and red chicory powders on colitis mice using non-group feeding cages was investigated. Further, the efficacy of whole celery, celery soluble dietary fiber (CSDF), celery insoluble dietary fiber (CIDF), celery flavonoids (CF), CSDF + CF and CIDF + CF in IBD mice model was assessed to dissect protective effect to attribute to which component(s) in such complex matrix. METHODS 3% Dextran sulfate sodium salt (DSS) was used to induce mice colitis model. Multiple molecular biological methods were employed to evaluate the severity of mice colitis and the gut microbial composition of mice. RESULTS Administration of kale and red chicory significantly restored body weight, DAI score, and colon length in colonic mice, and celery showed the weakest effects. Administration of either CSDF or CF markedly improved the histological damage, increased colonic mucus expression, and reduced colonic MPO/iNOS activities, and IL-6/IL-1β levels. However, CSDF + CF showed weaker improvement than CF or SDF in most physical and biochemical signs. Furthermore, CSDF and CF decreased intestinal g_Escherichia-Shihella and g_Clostridium_sensu_stricto_1 induced by DSS administration. Interestingly, celery flavonoid promoted g_Akkermansia proliferation both in vivo and in vitro, and which can be inhibited by CSDF. CONCLUSIONS This study revealed for the first time that CSDF can suppress the protective effect of CF on intestinal health by inhibiting g_Akkermansia, and clarified that the decreased efficacy of celery whole food on colitis was mediated by an antagonism between CSDF and CF. Moreover, this study presents for the first time that interaction between soluble dietary fiber and flavonoids in vivo can ameliorate the efficacy of dietary fiber or flavonoids when administered alone suggestive for an antagonistic effect.

Abstract
The COVID-19 pandemic caused by SARS-CoV-2 has majorly impacted public health and economies worldwide. Although several effective vaccines and drugs are now used to prevent and treat COVID-19, natural products, especially flavonoids, showed great therapeutic potential early in the pandemic and thus attracted particular attention. Quercetin, baicalein, baicalin, EGCG (epigallocatechin gallate), and luteolin are among the most studied flavonoids in this field. Flavonoids can directly or indirectly exert antiviral activities, such as the inhibition of virus invasion and the replication and inhibition of viral proteases. In addition, flavonoids can modulate the levels of interferon and proinflammatory factors. We have reviewed the previously reported relevant literature researching the pharmacological anti-SARS-CoV-2 activity of flavonoids where structures, classifications, synthetic pathways, and pharmacological effects are summarized. There is no doubt that flavonoids have great potential in the treatment of COVID-19. However, most of the current research is still in the theoretical stage. More studies are recommended to evaluate the efficacy and safety of flavonoids against SARS-CoV-2.

Combined Protective Effects of Quercetin, Rutin, and Gallic Acid against Cadmium-Induced Testicular Damages in Young-Adult Rats. Andrologia 2023.

Abstract
Cadmium (Cd) is a toxic metal that damages several tissues of animals and humans including the testis. The ameliorative effects of quercetin (QUE), rutin (RUT), and gallic acid (GAL) at 20 mg kg-1 body weight alone or in combination against testicular injury induced by Cd (24 mg kg-1 body weight) in male Wistar rats were evaluated in this study. Forty-two (42) rats were randomly grouped into six (6) groups: (1) vehicle control group, (2) Cd group, (3) RUT+Cd group, (4) GAL+Cd group, (5) QUE+Cd group, and (6) RUT+GAL+QUE+Cd group. At the end of the oral gavage of the tested chemicals, the rats were sacrificed, blood samples were collected, and testes were harvested and processed for biochemical assays. Cd exposure damaged the testis (smaller epithelium thickness and spermatogenesis index and sloughing of the epithelium); increased lipid peroxidation, glutathione S-transferase activity, and DNA fragmentation; and diminished glutathione reductase activity and serum testosterone level 40 days posttreatment. Treatment with the phenolics separately or in combination attenuated the effect of Cd on serum testosterone, glutathione reductase and glutathione S-transferase activities, lipid peroxidation, and percent fragmented DNA. The increased nitric oxide concentration in the QUE+Cd group was attenuated to control values in the combined (RUT+GAL+QUE+Cd) exposure group. Coadministration of the phenolics appears to have more substantial protective effects than their single effects against Cd-induced testicular DNA damage, glutathione S-transferase activity, and the recovery of testosterone levels and spermatogenesis index. Overall, the tested phenolics can reduce testicular damage more efficiently in their combined form than individual administration.

Abstract
Ulcerative colitis (UC) is an inflammatory bowel disease generally characterized by chronic, persistent, recurrent, and non-specific ulcers of the intestine. Its main clinical manifestations include abdominal pain, diarrhea, and bloody stools. This disease is difficult to cure and even carries the risk of canceration. It has been listed as a modern refractory disease by the World Health Organization. Though a large amount of drugs are available for the inhibition of UC, the conventional treatment such as aminosalicylic acids, glucocorticoids, immunosuppressors, and biological agents possess certain limitations and serious side effects. Therefore, it is urgently needed for safe and effective drugs of UC, and natural-derived flavonols and flavanones showed tremendous potential. The present study concentrated on the progress of natural-derived flavonols and flavanones from edible and pharmaceutical plants for the remedy of UC over the last two decades. The potential pharmaceutical of natural-derived flavonols and flavanones against UC were closely connected with the modulation of gut microflora, gut barrier function, inflammatory reactions, oxidative stress, and apoptosis. The excellent efficacy and safety of natural flavonols and flavanones make them prospective drug candidates for UC suppression.

Abstract
Faba beans are among the legumes that are of the greatest importance due to their high nutritional value. In addition to the essential nutrients that faba beans contain, they also contain bioactive compounds such as phenolics and flavonoids that are considered as potent natural antioxidants. Ulcerative colitis (UC) is an inflammatory bowel disease in which oxidative stress plays an essential role in the pathophysiology. The aim of the current study was to evaluate the antioxidant activity of faba bean seeds harvested from plants grown from seeds pre-treated with selenium, garlic husk extract and/or lemon peel extract and to evaluate their in vivo effects in a rat model of UC. 54 female rats were divided randomly into nine groups (n = 9). All groups were given the different tested treatments 14 days prior to UC induction using acetic acid (intra-rectal injection of 2 ml, 4% v/v in saline). Our results revealed that the treatment of faba bean seeds with a mixture of selenium, garlic husk extract and lemon peel extract before planting led to a significant increase in selenium, nitrogen, potassium, total protein, phenolic and flavonoid content in the harvested faba bean seeds with a subsequent enhancement of their antioxidant capacity. Consumption of such faba beans showed potential protective and therapeutic effects during experimental colitis by reducing colonic oxidative stress and increasing colonic antioxidant defense mechanisms. Further research is required to understand the mechanisms by which faba beans influence colitis, their effects on various inflammatory biomarkers and their impact on the severity of colitis in humans.

Abstract
BACKGROUND Inflammatory bowel disease (IBD) is a chronic, potentially cancerous disease with limited treatment options. Quercetin may be a novel treatment for IBD. However, its efficacy and safety are unknown. Our goal was to conduct a systematic evaluation to summarize the preclinical effects of quercetin, which may help guide future studies. METHODS The literature was drawn from three English databases (PubMed, Embase, and Web of Science), and the quality of the included literature was assessed using the SYRCLE list (10 items). The meta-analysis was performed using STATA 15.1 software. RESULTS A total of 11 animal studies with 199 animals were involved. The current meta-analysis showed that quercetin could reduce histological score (HS), Disease Activity Index (DAI), interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α), nitric oxide(NO), malondialdehyde (MDA), myeloperoxidase (MPO) activity and increase colon length (CL), weight change degree (WCD), interleukin-10 (IL-10), glutathione (GSH), superoxide dismutase (SOD) activity and catalase (CAT) activity, which may involve anti-inflammatory, anti-oxidative stress, cytoprotective, barrier protection, flora regulation. CONCLUSIONS In conclusion, preclinical evidence suggests that quercetin is an ideal agent for IBD treatment. However, the validity of the findings may be compromised by the low methodological quality and the small number of studies included. There may be some discrepancies between the results of the current analysis and the real situation. More rigorous experimental designs and more comprehensive studies are needed to test the protection of quercetin against IBD.

An Artemisia ordosica extract: Effects on growth performance, immune, and inflammatory response in lipopolysaccharide-challenged broilers. Front Vet Sci 2022; 9:980690. [PMID: 36157186 PMCID: PMC9500547 DOI: 10.3389/fvets.2022.980690] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2022] [Accepted: 08/22/2022] [Indexed: 11/13/2022] Open
Abstract
Artemisia ordosica has been applied as a traditional Chinese/Mongolian medicine for treating csertain inflammatory ailments. This study was conducted to investigate the effect of Artemisia ordosica alcohol extract (AOAE) supplemented in diets on growth performance, immune, and inflammatory response in lipopolysaccharide (LPS)-challenged broilers. A total of 240 one-day-old Arbor Acre male broilers were randomly allotted into 5 groups with 6 replicates (n = 8), which were basal diet group (CON), LPS-challenge and basal diet group (LPS), LPS-challenge and the basal diet added with low (500 mg/kg), middle (750 mg/kg), and high (1,000 mg/kg) dose of AOAE groups (AOAE-L, AOAE-M, and AOAE-H), respectively. On d 16, 18, 20, 22, 24, 26, and 28, all broilers were injected intra-abdominally either with LPS or an equivalent amount of saline. Results showed that dietary AOAE alleviated the LPS-induced decrease in average daily gain and average daily feed intake in the broilers (P < 0.05). Dietary AOAE supplementation reversed the increased spleen index and the decreased bursa index in LPS-challenged broilers (P < 0.05). Moreover, feeding AOAE could mitigate the elevation of IL-1β in serum, liver, and spleen, IL-2 in serum and liver, IL-6 in serum and spleen, and the decrease of IgG in spleen, IgM in serum, liver, and spleen, and IL-4 in serum of the LPS-challenged broilers (P < 0.05). This study also showed that AOAE supplementation alleviated the increase of mRNA expression of TLR4, MyD88, TRAF6, NF-κB p65, NF-κB p50, IL-1β, and IL-6, and the decrease of gene expression of IκBα and PPARγ in liver and/or spleen of broilers challenged by LPS (P < 0.05). We speculated that AOAE administration could effectively alleviate LPS-induced inflammation via decreasing over-production of proinflammatory cytokines, ultimately relieving the growth inhibition of broilers caused by LPS. In conclusion, 1,000 mg/kg AOAE has a strong capacity to enhance immunity and inhibit inflammation, and can be used as a potential novel feed additive with applications in treating inflammation-related diseases and bacterial infection in broilers.

Suitability of Banana and Plantain Fruits in Modulating Neurodegenerative Diseases: Implicating the In Vitro and In Vivo Evidence from Neuroactive Narratives of Constituent Biomolecules. Foods 2022; 11:foods11152263. [PMID: 35954031 PMCID: PMC9367880 DOI: 10.3390/foods11152263] [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: 11/20/2021] [Revised: 12/12/2021] [Accepted: 12/14/2021] [Indexed: 12/04/2022] Open
Abstract
Active principles in plant-based foods, especially staple fruits, such as bananas and plantains, possess inter-related anti-inflammatory, anti-apoptotic, antioxidative, and neuromodulatory activities. Neurodegenerative diseases affect the functionality of the central and peripheral nervous system, with attendant cognitive deficits being hallmarks of these conditions. The dietary constitution of a wide range of bioactive compounds identified in this review further iterates the significance of the banana and plantain in compromising, halting, or preventing the pathological mechanisms of neurological disorders. The neuroprotective mechanisms of these biomolecules have been identified by using protein expression regulation and specific gene/pathway targeting, such as the nuclear and tumor necrosis factors, extracellular signal-regulated and mitogen-activated protein kinases, activator protein-1, and the glial fibrillary acidic protein. This review establishes the potential double-edged neuro-pharmacological fingerprints of banana and plantain fruits in their traditionally consumed pulp and less utilized peel component for human nutrition.

Abstract
Oxidative stress is considered the main etiologic factor involved in inflammatory bowel disease (IBD). Integration of nanocarriers for natural therapeutic agents with antioxidant and anti-inflammatory potential is a novel promising candidate for curing IBD. Herein, the colonic antioxidant and anti-inflammatory effects of different concentrations of quercetin nanoparticles (QT-NPs) were evaluated using a dextran sulfate sodium (DSS)-induced colitis model. Following colitis induction, the efficacy and mechanistic actions of QT-NPs were evaluated by assessing lesion severity, molecular aids controlling oxidative stress and inflammatory response, and histopathological and immunohistochemistry examination of colonic tissues. Administration of QT-NPs, especially at higher concentrations, significantly reduced the disease activity index and values of fecal calprotectin marker compared to the colitic group. Colonic oxidant/antioxidant status (ROS, H2O2, MDA, SOD, CAT, GPX and TAC) was restored after treatment with higher concentrations of QT-NPs. Moreover, QT-NPs at levels of 20 mg/kg and, to a lesser extent, 15 mg/kg reduced Nrf2 and HO-1 gene expression, which was in line with decreasing the expression of iNOS and COX2 in colonic tissues. Higher concentrations of QT-NPs greatly downregulated pro-inflammatory cytokines; upregulated genes encoding occludin, MUC-2 and JAM; and restored the healthy architectures of colonic tissues. Taken together, these data suggest that QT-NPs could be a promising alternative to current IBD treatments.

Abstract
Autoimmune diseases are caused by the overactivity of the immune system towards self-constituents. Risk factors of autoimmune diseases are multiple and include genetic, epigenetic, environmental, and psychological. Autoimmune chronic inflammatory bowel diseases, including celiac and inflammatory diseases (Crohn's disease and ulcerative colitis), constitute a significant health problem worldwide. Besides the complexity of the symptoms of these diseases, their treatments have only been palliative. Numerous investigations showed that natural phytochemicals could be promising strategies to fight against these autoimmune diseases. In this respect, plant-derived natural compounds such as flavonoids, phenolic acids, and terpenoids exhibited significant effects against three autoimmune diseases affecting the intestine, particularly bowel diseases. This review focuses on the role of natural compounds obtained from medicinal plants in modulating inflammatory auto-immune diseases of the intestine. It covers the most recent literature related to the effect of these natural compounds in the treatment and prevention of auto-immune diseases of the intestine.

Abstract
Amaranthus species are widely cultivated as dietary crops and are promising sources of phytochemical compounds with antioxidant properties. To explore Amaranthus as a potential medical resource, 289 accessions (nine species) were cultivated, and their agricultural characteristics, total phenolic content (TPC), rutin contents, and antioxidant activities [2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2′-azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS)] were studied. Wide variations in agricultural traits, phytochemical contents, and antioxidant activities were observed between the accessions and across species. The effects of agricultural traits were evaluated, and the results indicated that yellow-flowered amaranth genotypes could be important because of their high values of TPC, rutin contents, DPPH, and ABTS. In addition, leaf length, days until 50% flowering, days until 50% heading and days until maturity, showed positive correlations with TPC, rutin contents, DPPH, and ABTS. The whole dataset was subjected to principal component analysis, and distinctive aggregation was observed across the Amaranthus species. In total, 289 accessions were clustered into three groups, and seven genotypes were determined as being good medical resources due to their high phytochemical content and antioxidant activities. Our findings provide important information for the development of new varieties with high phytochemical contents and high levels of antioxidant activity.

Abstract
TLR4/NF-κB is a key inflammatory signaling transduction pathway, closely involved in cell differentiation, proliferation, apoptosis, and pro-inflammatory response. Toll like receptor 4 (TLR4), the first mammalian TLR to be characterized, is the innate immune receptor that plays a key role in inflammatory signal transductions. Nuclear factor kappa B (NF-κB), the TLR4 downstream, is the key to accounting for the expression of multiple genes involved in inflammatory responses, such as pro-inflammatory cytokines. Inflammatory bowel disease (IBD) in humans is a chronic inflammatory disease with high incidence and prevalence worldwide. Targeting the TLR4/NF-κB signaling pathway might be an effective strategy to alleviate intestinal inflammation. Polyphenol phytochemicals have shown noticeable alleviative effects by acting on the TLR4/NF-κB signaling pathway in intestinal inflammation. This review summarizes the pharmacological effects of more than 20 kinds of polyphenols on intestinal inflammation via targeting the TLR4/NF-κB signaling pathway. We expected that polyphenol phytochemicals targeting the TLR4/NF-κB signaling pathway might be an effective approach to treat IBD in future clinical research applications.

Abstract
Hydroxylated polyphenols, also called flavonoids, are richly present in vegetables, fruits, cereals, nuts, herbs, seeds, stems, and flowers of numerous plants. They possess numerous medicinal properties such as antioxidant, anti-cancer, anti-microbial, neuroprotective, and anti-inflammation. Studies show that flavonoids activate antioxidant pathways that render an anti-inflammatory effect. They inhibit the secretions of enzymes such as lysozymes and β-glucuronidase and inhibit the secretion of arachidonic acid, which reduces inflammatory reactions. Flavonoids such as quercetin, genistein, apigenin, kaempferol, and epigallocatechin 3-gallate modulate the expression and activation of a cytokine such as interleukin-1beta (IL-1β), Tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), and interleukin-8 (IL-8); regulate the gene expression of many pro-inflammatory molecules such s nuclear factor kappa-light chain enhancer of activated B cells (NF-κB), activator protein-1 (AP-1), intercellular adhesion molecule-1 (ICAM), vascular cell adhesion molecule-1 (VCAM), and E-selectins; and also inhibits inducible nitric oxide (NO) synthase, cyclooxygenase-2, and lipoxygenase, which are pro-inflammatory enzymes. Understanding the anti-inflammatory action of flavonoids provides better treatment options, including coronavirus disease 2019 (COVID-19)-induced inflammation, inflammatory bowel disease, obstructive pulmonary disorder, arthritis, Alzheimer’s disease, cardiovascular disease, atherosclerosis, and cancer. This review highlights the sources, biochemical activities, and role of flavonoids in enhancing human health.

Abstract
Secoisolariciresinol diglucoside (SDG) has a strong anti-inflammatory effect, which depends partly on the participation of gut microbiota. We studied the effect of SDG on colonic inflammation caused by a common poor diet, high-fat diet (HFD), and the regulation of gut microbiota as well as its metabolites. Considering the difference of sources, prices, and possible bioactivity, we compared the effects of a single compound and the extract of SDG on colon inflammation. The results displayed that both the single compound and the extract ameliorated morphologic damage of the colon and improved intestinal barrier integrity. In addition, SDG suppressed the mRNA expressions of inflammatory cytokines in the colon, and the inhibitory effect of a single compound was stronger than that of the extract. The results of 16S rRNA sequencing showed that SDG altered the diversity and composition of gut microbiota, particularly the abundance of inflammation-related bacteria, and the effect of the extract was greater than that of a single compound. The analysis of short-chain fatty acids (SCFAs) manifested the improved concentration with the intervention of SDG. These results confirmed that SDG, including a single compound and extract, exerted protective effects against colon inflammation, which might be partly explained by the gut microbiome. Our research could provide a positive nutritional intervention for chronic intestinal inflammation.

Abstract
Abstract
Objectives Ulcerative colitis is a global disease with increasing incidence and worldwide prevalence. So this study was undertaken to observe antiulcerative colitis activity of ethanolic extract of seeds of Nelumbo nucifera plant on dextran sodium sulfate (DSS)-induced ulcerative colitis in rats.
Materials and Methods The effect of ethanolic extract of N. nucifera seed (EENNS) was studied on DSS-induced ulcerative colitis in albino Wistar rats for 11 days. Disease pathogenesis was assessed by evaluation of disease activity index (DAI) including the following parameters: change in body weight, stool constituency, rectal bleeding in animals. Estimation of myeloperoxide (MPO), nitric oxide (NO), and antioxidant parameters like malondialdehyde (MDA), superoxide dismutase (SOD), and catalase level was performed in colon homogenate of animals. TNF-α (tumor necrosis factor- α) level was measured in colon homogenate using rat TNF-α ELISA kit.
Statistical Analysis Significant differences (mean ± standard error of the mean) were detected using one-way analysis of variance followed by post-test using Graphpad prism 7.0 for multiple comparisons.
Results EENNS (400 mg/kg) significantly improved the disease progression, body weight, and colon length of the animals as compared with the disease control group. Animal treated with EENNS (400 mg/kg) showed significantly improved colon mucosal damage index (1.66 ± 0.21) and DAI (11.66 ± 4.01) as compared with the disease control group. A higher level of SOD and catalase and a lower level of MDA were observed in animals treated with EENNS (400 mg/kg) as compared with the disease control group. Animals treated with EENNS (400 mg/kg) significantly decreased in NO and MPO levels as compared with the disease control group. A lower level of TNF-α (561.94 ± 14.84) was observed in EENNS (400 mg/kg)-treated animals as compared with the disease control group (736.92 ± 15.3). These observations were comparable to those of the standard control group. Histopathological data showed that EENNS (400 mg/kg) has shown reversal of tissue inflammation as compared with the disease group and evidence of less cell infiltration of lymphocytes and monocytes with normal structures of goblet cell and crypts as compared with the disease group.
Conclusions EENNS (400 mg/kg) is endowed with severity of the ulcerative colitis produced by DSS. EENNS showed a protective effect against DSS-induced ulcerative colitis which may be due to its antioxidant and anti-inflammatory activity.

Abstract
The purpose of the current study was to investigate the effect of dietary dihydroquercetin (DHQ) supplementation on dextran sodium sulfate (DSS)-induced colitis in mice. Mice were given DHQ supplementation (3 g kg-1) throughout the study, starting 14 days prior to DSS treatment for 1 week followed by 2 days without DSS. The results showed that dietary DHQ supplementation restored DSS-induced disease activity index (DAI), colon length and histopathology scores of the colon tissue. Additionally, supplementation with DHQ reduced the pro-inflammatory cytokine levels, and enhanced the level of IL-10 in the serum. qPCR results indicated that DHQ supplementation significantly downregulated IL-1β, IL-6, and TNF-α, and upregulated IL-10 gene mRNA expression. Western blot results proved that DHQ supplementation upregulated ZO-1 and occludin levels. Using amplicon sequencing technology, 16S rRNA sequencing results showed that DHQ supplementation increased the fecal Firmicutes/Bacteroidetes ratio and the relative abundance of Lactobacillus and Dubosiella, and decreased the relative abundance of Bacteroidetes. Additionally, DHQ supplementation restored the decreased fecal acetic acid and butyric acid concentrations in DSS-induced colitis mice. Besides, Spearman's correlation analysis showed that Dubosiella was positively correlated with the butyric acid level and Bacteroidetes was positively correlated with the mRNA expression of IL-1β and IL-6. Both Lactobacillus and Dubosiella showed a negative correlation with the mRNA expression of IL-1β, IL-6, and TNF-α, and Dubosiella was positively correlated with IL-10. In summary, it was found that DHQ supplementation alleviated DSS-induced colitis which may be potentially associated with altered fecal microbiota communities in mice.

[PMID: 34950252 PMCID: PMC8648878 DOI: 10.1007/s13167-021-00257-y] [Citation(s) in RCA: 33] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2021] [Accepted: 09/22/2021] [Indexed: 12/15/2022]
Abstract
AbstractInflammation is an essential pillar of the immune defense. On the other hand, chronic inflammation is considered a hallmark of cancer initiation and progression. Chronic inflammation demonstrates a potential to induce complex changes at molecular, cellular, and organ levels including but not restricted to the stagnation and impairment of healing processes, uncontrolled production of aggressive ROS/RNS, triggered DNA mutations and damage, compromised efficacy of the DNA repair machinery, significantly upregulated cytokine/chemokine release and associated patho-physiologic protein synthesis, activated signaling pathways involved in carcinogenesis and tumor progression, abnormal tissue remodeling, and created pre-metastatic niches, among others. The anti-inflammatory activities of flavonoids demonstrate clinically relevant potential as preventive and therapeutic agents to improve individual outcomes in diseases linked to the low-grade systemic and chronic inflammation, including cancers. To this end, flavonoids are potent modulators of pro-inflammatory gene expression being, therefore, of great interest as agents selectively suppressing molecular targets within pro-inflammatory pathways. This paper provides in-depth analysis of anti-inflammatory properties of flavonoids, highlights corresponding mechanisms and targeted molecular pathways, and proposes potential treatment models for multi-level cancer prevention in the framework of predictive, preventive, and personalized medicine (PPPM / 3PM). To this end, individualized profiling and patient stratification are essential for implementing targeted anti-inflammatory approaches. Most prominent examples are presented for the proposed application of flavonoid-conducted anti-inflammatory treatments in overall cancer management.

(Euphorbiaceae): An overview of its botanical diversity, traditional uses, phytochemistry, pharmacological effects and perspectives towards developing its plant-based products. JOURNAL OF ETHNOPHARMACOLOGY 2021; 277:114244. [PMID: 34052354 DOI: 10.1016/j.jep.2021.114244] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/06/2021] [Revised: 05/05/2021] [Accepted: 05/24/2021] [Indexed: 06/12/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Codiaeum variegatum also called miracle shrub, is a plant species constituted of more than 300 cultivars which are mostly used as indoor plants for decoration. However, some of these varieties are used by indigenous populations for the treatment of diarrhoea, stomach ache, external wounds, intestinal worms and ulcers. AIM OF THE STUDY This study describes an overview of the botanical diversity, medicinal uses, phytochemical composition of C. variegatum. Then it critically discusses its pharmacological activities versus toxic potential and new perspectives are suggested for the development of its plant-based products. MATERIALS AND METHODS A bibliographic assessment of publications on C. variegatum indexed in Google Scholar, PubMed, Science Direct, Scopus, Springer Link, and Web of Science online databases was conducted from 1970 to 2020, and 89 relevant articles related to the botanical diversity (17), traditional uses (22), phytochemical analysis (11), pharmacological activity (31) and toxicity profile (18) of C. variegatum were selected for this review. RESULTS Most commonly, it was found that aqueous leaf extracts or decoctions of C. variegatum are used in traditional medicine to treat amoebic dysentery and stomach ache while a bath with root decoction or sap is applied in small quantities on skin related infections. A total of 14 identified and 24 non-identified varieties of C. variegatum were reported for pharmacological activity, and prominent research topics include the anti-amoebic, antimicrobial, antiviral and cytotoxic activities. Alkaloids (3), terpenoids (5) and phenolics (15) were the major compounds identified, and a new antiviral cyanoglucoside was isolated from the sap of C. variegatum. Toxic substances (5-deoxyingenol and phorbol esters) were found in some varieties used as ornamental plants, but the Mollucanum variety used in traditional medicine was found to be safe. CONCLUSION The present review revealed that the native variety of C. variegatum (cv. Mollucanum) can be used to treat amoebic dysentery. Alkaloids, terpenoids and phenolic compounds have been characterized in this plant species while other classes of phytochemicals are not yet investigated. The development of new cultivars recommends an in-depth toxicological study before any use. No clinical trial has been reported to date, and further studies are needed to evaluate other claimed medicinal uses. Due to its efficacy and safety, the Mollucanum variety is most likely suitable for the development of a medicine against amoebiasis, which will surely lay the foundation for clinical studies.

Abstract
A large body of emerging evidence has revealed the role of p38/MK2 and PI3K/Akt/GSK3β cascades in the orchestrating process of colitis. Rutin, a bioflavonoid present in many fruits and vegetables, has been recognized to offer therapeutic attributes in acute colitis. However, its role in chronic colitic condition has not yet been delineated in reference to p38/MK2 and PI3K/Akt/GSK3β signalling. The present investigation assessed the efficacy and underlying molecular mechanism of rutin in alleviating DSS-induced chronic colitis. The analysis of signalling pathways demonstrated the robust activation of PI3K/Akt/GSK3β/MAPKs/NF-κB and p38/MK2 in DSS-induced colitis in animals, which was efficiently alleviated following the rutin treatment. In silico studies indicated its target specificity with these pathways. Rutin administration markedly improved the disease activity score, colon length, goblet cell loss and compromised colon epithelial integrity in colitic mice. Decreased expression of oxi-inflammatory markers such as IgM, IgE, iNOS, ICAM-1, HO-1 and Th1/IL-10 cytokines ratios after treatment suggests its efficacy in regulating effector, regulatory and B cell homeostasis. Additionally, rutin demonstrated its role in restoring epithelial integrity by modulating the transcript levels of tight junction proteins, mucus-secreting proteins, epithelial cell proliferation and apoptosis. Treg expansion revealed that rutin supplementation also exhibits an immune regulatory potential and suppresses inflammatory aggravation mediated by adaptive immune responses. Overall, results indicate that the modulation of p38/MK2 and PI3K/Akt/GSK3β/NF-κB pathways by rutin represents a novel therapeutic approach in chronic colitis that help to curb dysregulated intestinal integrity, cytokine ratio and splenic Tregs.

Abstract
Inflammatory bowel disease (IBD) is a chronic and idiopathic inflammatory disorder affecting the gastrointestinal tract. The pharmacological treatments used currently for its treatment lack efficacy, so new therapeutic strategies should be developed. In this context, flavonoids loaded in biopolymeric nanoparticles can be considered as novel promising candidates. The aim of the present study was to evaluate the intestinal anti-inflammatory effects of quercetin when is administered loaded in silk fibroin nanoparticles (QSFN) in the dextran sulphate sodium experimental model of mouse colitis, which displays some similarities to human IBD. Previously characterized quercetin-loaded silk fibroin nanoparticles (QSFN). QSFN showed a reversible aggregation profile induced by the acidification of the solution but did not affect the loaded quercetin. Daily administration of QSFN significantly reduced disease activity index values compared to the control colitic group. This beneficial effect was not only corroborated by the histological examination of the colonic specimens but also the improvement of the colonic expression of the different proinflammatory cytokines (Tnf-α, Il-1β, Il-6, Mcp-1, Icam-1, Nlrp3 and iNOS). Therefore, these data suggest that QSFN could be a promising alternative to current treatments as a drug delivery system for IBD treatment.

Abstract
Autoimmune diseases are a worldwide health problem with growing rates of morbidity, and are characterized by breakdown and dysregulation of the immune system. Although their etiology and pathogenesis remain unclear, the application of dietary supplements is gradually increasing in patients with autoimmune diseases, mainly due to their positive effects, relatively safety, and low cost. Quercetin is a natural flavonoid that is widely present in fruits, herbs, and vegetables. It has been shown to have a wide range of beneficial effects and biological activities, including anti-inflammation, anti-oxidation, and neuroprotection. In several recent studies quercetin has reportedly attenuated rheumatoid arthritis, inflammatory bowel disease, multiple sclerosis, and systemic lupus erythematosus in humans or animal models. This review summarizes the evidence for the pharmacological application of quercetin for autoimmune diseases, which supports the view that quercetin may be useful for their prevention and treatment.

Abstract
The Mediterranean diet is a central element of a healthy lifestyle, where polyphenols play a key role due to their anti-oxidant properties, and for some of them, as nutripharmacological compounds capable of preventing a number of diseases, including cancer. Due to the high prevalence of intestinal cancer (ranking second in causing morbidity and mortality), this review is focused on the beneficial effects of selected dietary phytophenols, largely present in Mediterranean cooking: apigenin, curcumin, epigallocatechin gallate, quercetin-rutine, and resveratrol. The role of the Mediterranean diet in the prevention of colorectal cancer and future perspectives are discussed in terms of food polyphenol content, the effectiveness, the plasma level, and the importance of other factors, such as the polyphenol metabolites and the influence of the microbiome. Perspectives are discussed in terms of microbiome-dependency of the brain-second brain axis. The emergence of polyphenol formulations may strengthen the efficiency of the Mediterranean diet in the prevention of cancer.

Abstract
A disturbed interaction between the gut microbiota and the mucosal immune system plays a pivotal role in the development of inflammatory bowel disease (IBD). Various compounds that are produced by the gut microbiota, from its metabolism of diverse dietary sources, have been found to possess anti-inflammatory and anti-oxidative properties in in vitro and in vivo models relevant to IBD. These gut microbiota-derived metabolites may have similar, or more potent gut homeostasis-promoting effects compared to the widely-studied short-chain fatty acids (SCFAs). Available data suggest that mainly members of the Firmicutes are responsible for producing metabolites with the aforementioned effects, a phylum that is generally underrepresented in the microbiota of IBD patients. Further efforts aiming at characterizing such metabolites and examining their properties may help to develop novel modulatory microbiome therapies to treat or prevent IBD.

Abstract
Red yeast rice (RYR), a traditional Chinese fermented food, has the effect of lowering blood lipid and cholesterol, but little information is available about whether RYR can inhibit pathogenic bacterial infection in vivo. The present study explored the effect of RYR on Salmonella enterica-induced intestinal inflammation and gut microbiota dysbiosis in mice as well as the underlying anti-inflammatory mechanism. Results showed that RYR can alleviate S. enterica infection in vivo and Monascus pigments are the main functional components. The analysis of microbiota, gene expression profile and serological immunology revealed that RYR can regulate the intestinal flora and increase the relative abundance of beneficial bacteria such as Lactobacillus and Akkermansia. Meanwhile, RYR is also found to regulate the expression of pro-inflammatory factors and tight junction-related genes to inhibit the NO and NF-κB-mediated inflammatory response and maintain the integrity of the intestinal barrier. This study provides a new dietary intervention strategy for the prevention of pathogenic bacterial infection.

Abstract
Increased 5-hydroxytryptamine may be associated with the development and progression of inflammatory bowel disease. In this study, we examined the suppressive effect of flavonoids on the increased intra- and extracellular 5-hydroxytryptamine levels in rat mast RBL-2H3 cells, known to produce 5-hydroxytryptamine by the phorbol 12-myristate 13-acetate stimulation. Among the flavonoids examined, luteolin and quercetin significantly reduced the cellular 5-hydroxytryptamine concentration. Gene and protein expression analyses revealed that luteolin significantly suppressed cellular tryptophan hydroxylase 1 expression induced by phorbol 12-myristate 13-acetate stimulation. Mitogen-activated protein kinase/extracellular signal-regulated kinase signaling was also suppressed by luteolin, suggesting that this pathway is one of targets of 5-hydroxytryptamine modulation by luteolin. An in vivo experimental colitis model was prepared by administering 2.5% dextran sodium sulfate in drinking water to C57BL/6 mice for seven days. The ingestion of 0.1% dietary luteolin suppressed the increasing 5-hydroxytryptamine in the colorectal mucosa. In conclusion, luteolin possesses a suppressive effect on extensive 5-hydroxytryptamine formation in both experimental RBL-2H3 cells and colitis models.

Abstract
Inflammatory bowel diseases (IBD) are illnesses characterized by chronic intestinal inflammation and microbial dysbiosis that have emerged as a public health challenge worldwide. It comprises two main conditions: Crohn's disease and ulcerative colitis. Currently, conventional therapy to treat IBD are not free from side effects, such as liver and kidney toxicity, drug resistance, and allergic reactions. In view of this, there is growing research for alternative and complementary therapies that, in addition to acting in the prevention or the control of the disease, do not compromise the quality of life and health of individuals. In this sense, a growing body of evidence has confirmed the benefits of natural phenolic compounds in intestinal health. Phenolic compounds or polyphenols are molecules widely distributed throughout the plant kingdom (flowers, vegetables, leaves, and fruits), including plant materials remaining of the handling and food industrial processing, referred to in the scientific literature as by-products, food waste, or bagasse. Since by-products are low-cost, abundant, easily accessible, safe, and rich in bioactive compounds, it becomes an exciting option to extract, concentrate or isolate phenolic compounds to be posteriorly applied in the therapeutic approach of IBD. In this article, we have reviewed the main phenolic compounds present in various plants and by-products that have shown beneficial and/or promising effects in experimental pre-clinical, clinical, and in vitro research with IBD. In addition, we have mentioned and suggested several plants and by-products originated and produced in Latin America that could be part of future research as good sources of specific phenolic compounds to be applied in the prevention and development of alternative treatments for IBD. This review may offer a valuable reference for studies related to IBD administering phenolic compounds from natural, cheap, and easily accessible raw and undervalued materials.

Wu B, Chang H, Marini R, Chopra S, Reddivari L. Characterization of Maize Near-Isogenic Lines With Enhanced Flavonoid Expression to Be Used as Tools in Diet-Health Complexity. FRONTIERS IN PLANT SCIENCE 2021; 11:619598. [PMID: 33584759 PMCID: PMC7874058 DOI: 10.3389/fpls.2020.619598] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 10/20/2020] [Accepted: 12/21/2020] [Indexed: 06/12/2023]
Abstract
Increasing incidence of chronic diseases in the 21st century has emphasized the importance of developing crops with enhanced nutritional value. Plant-based diets are associated with reduced incidence of many chronic diseases. The growing population and increased food demand have prioritized the development of high-yielding commercial crop varieties at the expense of natural flavors as well as health-benefiting compounds including polyphenols. Flavonoids are a large subfamily of polyphenols abundant in the plant kingdom with known health-promoting effects, making them a promising trait to be re-introduced into elite lines. Given the vast array of flavonoids and the complexity of plant food metabolome interactions, it is difficult to identify with certainty the specific class(es) of flavonoids in the food matrix that are anti-inflammatory. To address this, we have developed four maize near-isogenic lines (NILs); a line that lacked both anthocyanins and phlobaphenes, a second NIL containing phlobaphenes, a third line had anthocyanins, and a fourth line that contained both anthocyanins and phlobaphenes. The phytochemical profiles and the antioxidant potential of the NILs were characterized. The accumulation of anthocyanins and phlobaphenes contributed significantly to antioxidant capacity compared to maize lines that lacked one or both of the compounds (p < 0.05). Pilot study showed that intake of flavonoid-rich maize diets were able to alleviate experimental colitis in mice. These NILs offer novel materials combining anthocyanins and phlobaphenes and can be used as powerful tools to investigate the disease-preventive effects of specific flavonoid compound in diet/feeding experiments.

Anti-inflammatory and bioavailability studies on dietary 3,5,4'-trihydroxy-6,7-methylenedioxyflavone-O-glycosides and their aglycone from indigo leaves in a murine model of inflammatory bowel disease. J Pharm Biomed Anal 2020; 193:113716.

Abstract
Persicaria tinctoria (Aiton) Spach, also called Polygonum tinctorium Lour., (family Polygonaceae) for indigo plant has been traditionally useful as a medicinal or edible plant with a variety of biological activities. Of these, much attention has been paid to their anti-inflammatory activities. We have recently demonstrated that indigo leaves contain high levels of flavonol O-glycosides with 3,5,4'-trihydroxy-6,7-methylenedioxyflavone (TMF) as an aglycone. In this study, we attempted to evaluate anti-inflammatory activities of TMF-O-glycosides and free TMF prepared from indigo leaves after extraction with hot water. Free TMF was found to appreciably down-regulate the gene expression of pro-inflammatory cytokines including interleukin (IL)-1β, IL-6, inducible nitric oxide, and tumor necrosis factor-α in cultured macrophage cells stimulated with lipopolysaccharide while up-regulating the expression of anti-inflammatory IL-10. However, no study has been conducted regarding in vivo anti-inflammatory activities of TMF-O-glycosides and free TMF until now. Here, we assessed in vivo anti-inflammatory effects of these dietary compounds on ulcerative colitis in a murine model of inflammatory bowel disease by the induction with dextran sulfate sodium (DSS). Histological evaluation revealed that both TMF-O-glycosides and free TMF effectively protected against DSS-induced ulcerative colitis. The analysis of digested products by liquid chromatography and mass spectrometry led us to detect free TMF as a predominant metabolite in the feces of mice fed with TMF-O-glycosides. Moreover, free TMF was later detected as glucuronyl conjugates of TMF in the liver of mice fed with both fractions. These results indicate the effective digestion of TMF-O-glycosides and the subsequent absorption of free TMF in the gut of mice for exerting anti-inflammatory effects. Taken together, our findings suggest that dietary TMF-O-glycosides could be promising natural sources for the utilization as herbal medicine and nutraceuticals to expect in vivo anti-inflammatory activities.

Abstract
A response surface methodology was used to study the conditions for a maximum recovery of phenolics from processing kiwi fruit residues. Ethanolic extracts were prepared with different conditions of pH (2, 5, 10), temperature (30, 50 and 70 ºC) and time (10, 20, 30 min). Total phenolics, total flavonoids content and antioxidant activities by 2,2-diphenyl-1-picrylhydrazyl scavenging capacity and ferric reducing antioxidant power were determined. Samples from optimal extraction condition were injected HPLC-DAD system to access the phenolic profile and content. The best extraction conditions were pH solvent of 2, 70 ºC of temperature and 20 min of extraction. Ten phenolics were identified: caffeic acid and its derivatives, chlorogenic acid and ferulic acid, (+)-catechin, (-)-epicatechin), rutin and quercitrin. These phenolics often reported as having important antioxidant, anti-inflammatory, antiaging and anticancer activities, turn this residues and excellent source of bioactive compounds to be used in agro-food, cosmetics or phytochemical industries.

Abstract
Sesamol, a liposoluble lignan extract, has already been proved to possess potent anti-inflammatory properties, and it could also regulate gut dysfunction. The purpose of the present research is to explore the protective effect of sesamol on colitis mice. In the current research, sesamol treatment (100 mg/kg bodyweight/day) for 6 weeks inhibited the dextran sulphate sodium (DSS)-induced bodyweight loss of mice. Transmission electron microscopy and hematoxylin and eosin staining results showed that the DSS-induced histopathological changes of mice were also recovered by sesamol supplementation. In addition, DSS-induced inflammatory responses were inhibited by sesamol supplementation via the NF-κB signaling pathway in mice colon. Moreover, sesamol treatment prevented gut barrier damages by enhancing the expression of tight junction proteins (occludin, claudin-1, and ZO-1) and recovering the loss of gut mucus layer. Furthermore, sesamol supplementation also increased the short-chain fatty acid (SCFAs) contents of acetate, propionate, and butyrate. Furthermore, sesamol supplementation changed the gut microbiome structure by enhancing the relative abundance of Coprococcuscus, Butyricicoccus, Odoribacter, and AF12 in colitis mice. In conclusion, sesamol could effectively ameliorate DSS-induced colitis by promoting gut microecology.

Abstract
Phenolic compounds that are present in amaranth crops have gained a lot of interest from researchers due to their health benefits potential. Therefore, the aim of this study was to investigate phenolic compounds present in different plant parts of Amaranthuscruentus using liquid chromatography-electrospray ionization quadrupole time-of-flight mass spectrometry. Moreover, data were analyzed by one-way analysis of variance of the statistical analysis software, whereas commercial statistical package version 4.02 was used for principal component analysis. A total of 21 phenolic compounds were detected and eight were not identified. Caffeoylsaccharic acid isomer, coumaoryl saccharic acid, tryptophan, feruloyl-d-saccharic acid isomer a, b, and c, caffeoyl isocitrate, quercetin 3-O-rhamnosyl-rhamnosyl-glucoside, feruloyl isocitrate, hyperoside, kaempferol rutinoside, and alkaloid compounds were mostly detected in tender and mature leaves. Generally, rutin content was higher (p < 0.05) in most vegetative parts of the amaranth plant, thus, late maturity leaves, tender leaves, and mature leaves, respectively. Lower quantities of rutin were observed in tender grains, flowers, and mature grains. It can be concluded that amaranth contains phenolic compounds, predominantly in the vegetative parts, which makes it to be a promising source of phenolic compounds beneficial to human health.

Abstract
Inflammation is a physiological response to different pathological, cellular or vascular damages due to physical, chemical or mechanical trauma. It is characterized by pain, redness, heat and swelling. Current natural drugs are carefully chosen as a novel therapeutic strategy for the management of inflammatory diseases. Different phytochemical constituents are present in natural products. These phytochemicals have high efficacy both in vivo and in vitro. Among them, flavonoids occur in many foods, vegetables and herbal medicines and are considered as the most active constituent, having the ability to attenuate inflammation. Kaempferol is a polyphenol that is richly found in fruits, vegetables and herbal medicines. It is also found in plant-derived beverages. Kaempferol is used in the management of various ailments but there is no available review article that can summarize all the natural sources and biological activities specifically focusing on the anti-inflammatory effect of kaempferol. Therefore, this article is aimed at providing a brief updated review of the literature regarding the anti-inflammatory effect of kaempferol and its possible molecular mechanisms of action. Furthermore, the review provides the available updated literature regarding the natural sources, chemistry, biosynthesis, oral absorption, metabolism, bioavailability and therapeutic effect of kaempferol.

Abstract
Ulcerative colitis (UC) is an inflammatory bowel disease with increasing incidence in the world, especially in developing countries. Although knowledge of its pathogenesis has progressed over the last years, some details require clarification. Studies have highlighted the role of microbial dysbiosis and immune dysfunction as essential factors that may initiate the typical high-grade inflammatory outcome. In order to better understand the immunopathophysiological aspects of UC, experimental murine models are valuable tools. Some of the most commonly used chemicals to induce colitis are trinitrobenzene sulfonic acid, oxazolone and dextran sodium sulfate. These may also be used to investigate new ways of preventing or treating UC and therefore improving targeting in human studies. The use of functional foods or bioactive compounds from plants may constitute an innovative direction towards the future of alternative medicine. Considering the above, this review focused on updated information regarding the 1. gut microbiota and immunopathogenesis of UC; 2. the most utilized animal models of the disease and their relevance; and 3. experimental application of natural products, not yet tested in clinical trials.

Abstract
Inflammatory bowel disease (IBD) refers to a group of disorders characterized by chronic inflammation of the gastrointestinal (GI) tract. The elevated levels of nitric oxide (NO) in serum and affected tissues; mainly synthesized by the inducible nitric oxide synthase (iNOS) enzyme; can exacerbate GI inflammation and is one of the major biomarkers of GI inflammation. Various natural and synthetic agents are able to ameliorate GI inflammation and decrease iNOS expression to the extent comparable with some IBD drugs. Thereby, the purpose of this study was to gather a list of natural or synthetic mediators capable of modulating IBD through the NO pathway. Electronic databases including Google Scholar and PubMed were searched from 1980 to May 2018. We found that polyphenols and particularly flavonoids are able to markedly attenuate NO production and iNOS expression through the nuclear factor κB (NF-κB) and JAK/STAT signaling pathways. Prebiotics and probiotics can also alter the GI microbiota and reduce NO expression in IBD models through a broad array of mechanisms. A number of synthetic molecules have been found to suppress NO expression either dependent on the NF-κB signaling pathway (i.e., dexamethasone, pioglitazone, tropisetron) or independent from this pathway (i.e., nicotine, prednisolone, celecoxib, β-adrenoceptor antagonists). Co-administration of natural and synthetic agents can affect the tissue level of NO and may improve IBD symptoms mainly by modulating the Toll like receptor-4 and NF-κB signaling pathways.

Abstract
The gastrointestinal tract is exposed to pro-oxidants from food, host immune factors, and microbial pathogens, which may induce oxidative damage. Oxidative stress has been shown to play an important role in the onset of inflammatory bowel disease. This study aimed to use a novel model to evaluate the effects of a screened natural component and explore its possible mechanism. An in vitro oxidative stress Caco2 cell model induced by H2O2 was established using a real-time cellular analysis system and verified by addition of glutathione (GSH). A variety of plant components were chosen for the screening. Quercetin was the most effective phytochemical to alleviate the decreased cell index caused by H2O2 among the tested plant components. Furthermore, quercetin ameliorated dextran sulfate sodium salt (DSS)-induced colitis and further increased the serum GSH. The mechanism of quercetin protection was explored in Caco2. Reversed H2O2-induced cell damage and decreased reactive oxygen species and apoptosis ratio were observed in quercetin-treated cells. Also, quercetin increased expression of the glutamate-cysteine ligase catalytic subunit (GCLC), the first rate-limiting enzyme of glutathione synthesis, and increased intracellular GSH concentration under H2O2 treatment. This effect was abolished by the GCLC inhibitor buthionine sulfoximine. These results indicated that quercetin can improve cell proliferation and increase intracellular GSH concentrations by upregulating transcription of GCLC to eliminate excessive reactive oxygen species (ROS). Increased extracellular H2O2 concentration induced by quercetin under oxidative stress was related to the inhibition of AQP3 and upregulation of NOX1/2, which may contribute to the observed protective effects of quercetin. Moreover, the novel H2O2-induced oxidative stress cell model based on the real-time cellular analysis system was an effective model to screen natural products to deal with intestinal oxidative damage and help accelerate the discovery of new drugs for inflammatory bowel disease (IBD).

Abstract
Inflammatory bowel disease (IBD) is characterized by severe mucosal damage in the intestine and a deregulated immune response. Natural products derived from plants that are rich in bioactive compounds are used by many patients with IBD. Xique-xique (Pilosocereus gounellei) is a cactus of the Caatinga family that has been used by the local population for food and medicinal purposes. The intestinal anti-inflammatory effect of xique-xique cladode juice was evaluated in the present study. A dose of 5 mL kg-1 had a protective effect on intestinal inflammation, with an improvement in macroscopic damage, and a decrease in pro-inflammatory markers and oxidative stress, in addition to preserving the colonic tissue. Immunohistochemical analysis revealed the downregulation of IL-17, NF-κB, and iNOS, and upregulation of SOCs-1, ZO-1, and MUC-2. These protective effects could be attributed to the phenolic compounds as well as the fibers present in xique-xique juice. Further studies are needed before suggesting the use of xique-xique juice as a new alternative for treating IBD.

The Effect of Dietary Quercetin on the Glutathione Redox System and Small Intestinal Functionality of Weaned Piglets. Antioxidants (Basel) 2019; 8:antiox8080312. [PMID: 31426309 PMCID: PMC6720349 DOI: 10.3390/antiox8080312] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2019] [Revised: 08/08/2019] [Accepted: 08/11/2019] [Indexed: 12/11/2022] Open
Abstract
Quercetin has been shown to alleviate mucosal damage and modulate the glutathione (GSH) redox system in the colon of rodents. In the current study, we assessed whether quercetin was able to mitigate small intestinal dysfunction in weaned pigs. Here, 224 weaned piglets were fed a diet containing quercetin at either 0, 100, 300, or 900 mg/kg diet until d14 post-weaning, followed by a common basal diet until d42. Eight animals per treatment were sampled at d5 and d14 post-weaning. In these animals, the small intestinal histomorphology, barrier function, and protein abundance of occludin, caspase-3, and proliferating cell nuclear antigen were assessed. None of these parameters were affected, and neither did quercetin improve performance up to d42 post-weaning. The GSH redox system was evaluated in blood, small intestinal mucosa, and liver. Quercetin did not affect the glutathione peroxidase, glutathione reductase, and glutamate–cysteine ligase activity in these tissues. In contrast, the hepatic glutathione transferase (GST) activity was significantly increased by quercetin supplementation at d5 post-weaning of 100, 300, and 900 mg/kg. Importantly, d5 was characterized by a more oxidized GSH redox status. To conclude, dietary quercetin had little effect on the small intestine, but did upregulate hepatic GST in the occurrence of redox disturbance.

Abstract
Colorectal cancer (CRC) is one of the leading causes of mortality among men and women. Chemo-resistance, adverse effects and disease recurrence are major challenges in the development of effective cancer therapeutics. Substantial literature on this subject highlights that populations consuming diets rich in fibers, fruits and vegetables have a significantly reduced incidence rate of CRC. This chemo-preventive effect is primarily associated with the presence of phytochemicals in the dietary components. Plant-derived chemical agents act as a prominent source of novel compounds for drug discovery. Phytochemicals have been the focus of an increasing number of studies due to their ability to modulate carcinogenic processes through the alteration of multiple cancer cell survival pathways. Despite promising results from experimental studies, only a limited number of phytochemicals have entered into clinical trials. The purpose of the current review is to compile previously published pre-clinical and clinical evidence of phytochemicals in cases of CRC. A PubMed, Google Scholar and Science Direct search was performed for relevant articles published between 2008-2018 using the following key terms: 'Phytochemicals with colorectal cancers', 'apoptosis', 'cell cycle', 'reactive oxygen species' and 'clinical anticancer activities'. The present review may aid in identifying the most investigated phytochemicals in CRC cells, and due to the limited number of studies that make it from the laboratory bench to clinical trial stage, may provide a novel foundation for future research.

Abstract
Inflammatory bowel disease (IBD), with its major manifestations being Crohn's disease and ulcerative colitis, belongs to the gastrointestinal inflammatory disorders, whose main therapeutic approach is represented by synthetic anti-inflammatory drugs. However, they are often accompanied by many side effects that shifted the interest of the scientific community towards natural products. In this context, several studies asserted the anti-IBD effects of Citrus fruits and their flavonoids, thus the aim of the present review is to provide robust evidence favouring their role in the prevention and treatment of IBD. Key mechanisms relate to their anti-inflammatory and antioxidant properties, as well as their ability to modulate gut microbiota. All the findings collected in this review, lay the foundations for further studies in human with the aim of evaluating the concrete applicability as a novel preventive and therapeutic approach of Citrus fruits and their flavonoids.[Figure: see text].

Abstract
Gastrointestinal tract is the second largest organ in the body that mainly functions in nutrients and minerals intake through the intestinal barrier. Intestinal permeability maintains the circulation of minerals and nutrients from digested foods. Life and all the metabolic processes depend either directly or indirectly on proper functioning of GI tract. Compromised intestinal permeability and related disorders are common among all the patients with inflammatory bowel disease (IBD), which is a collective term of inflammatory diseases including Crohn's disease and ulcerative colitis. Many synthetic drugs are currently in use to treat IBD such as 5-aminosalicylic acid corticosteroids. However, they all have some drawbacks as long-term use result in many complications. These problems encourage us to look out for alternative medicine. Numerous in vitro and in vivo experiments showed that the plant-derived secondary metabolites including phenolic compounds, glucosinolates, alkaloids, terpenoids, oligosaccharides, and quinones could reduce permeability, ameliorate-related dysfunctions with promising results. In addition, many of them could modulate enzymatic activity, suppress the inflammatory transcriptional factors, ease oxidative stress, and reduce pro-inflammatory cytokines secretion. In this review, we summarized the phytochemicals, which were proven potent in treating increased intestinal permeability and related complication along with their mechanism of action.

Abstract
Inflammation has been reported to be intimately linked to the development or worsening of several non-infectious diseases. A number of chronic conditions such as cancer, diabetes, cardiovascular disorders, autoimmune diseases, and neurodegenerative disorders emerge as a result of tissue injury and genomic changes induced by constant low-grade inflammation in and around the affected tissue or organ. The existing therapies for most of these chronic conditions sometimes leave more debilitating effects than the disease itself, warranting the advent of safer, less toxic, and more cost-effective therapeutic alternatives for the patients. For centuries, flavonoids and their preparations have been used to treat various human illnesses, and their continual use has persevered throughout the ages. This review focuses on the anti-inflammatory actions of flavonoids against chronic illnesses such as cancer, diabetes, cardiovascular diseases, and neuroinflammation with a special focus on apigenin, a relatively less toxic and non-mutagenic flavonoid with remarkable pharmacodynamics. Additionally, inflammation in the central nervous system (CNS) due to diseases such as multiple sclerosis (MS) gives ready access to circulating lymphocytes, monocytes/macrophages, and dendritic cells (DCs), causing edema, further inflammation, and demyelination. As the dearth of safe anti-inflammatory therapies is dire in the case of CNS-related disorders, we reviewed the neuroprotective actions of apigenin and other flavonoids. Existing epidemiological and pre-clinical studies present considerable evidence in favor of developing apigenin as a natural alternative therapy against chronic inflammatory conditions.

Abstract
Rutin, also known as vitamin P or rutoside, has been explored for many pharmacological activities. Apples, tea leaves, and many other plants contain rutin as one of the active constituents. Haematological, immunological indices and the expression of inflammatory cytokine genes in spleen tissue were assessed to investigate the influence of different levels of dietary rutin supplement (0.25, 0.5, or 1 g/kg diet) on the immune response of broilers. After 6 weeks, rutin-fed chickens showed an increase in the haematological indices, including the number of blood lymphocytes. Similarly, serum total protein and globulin were also elevated. By contrast, serum cholesterol, triglycerides and liver enzymes were lower in the experimental birds than in the control birds. Moreover, compared with the control birds, there was no significant change in the bilirubin concentration, either total or direct, and kidney-function indices in response to rutin supplementation in the experimental birds. Among the immune parameters examined, lysozyme activity, nitric oxide concentrations, and immunologlobulin M (IgM) production were significantly higher in rutin-fed birds than in the control birds; however, there was no significant effect of rutin at any concentration on the IgG and IgA concentrations and lymphoid organ weight. Of the cytokine-encoding genes studied, the genes encoding interleukin-6, nuclear-factor kappa B, and tumour-necrosis factor-α were upregulated in the spleen of the experimental birds, while the expression of interferon gamma-encoding gene was unaffected in the experimental birds. Here, rutin promoted the immune strength in birds mainly at 1 g/kg diet, suggesting that rutin is a promising feed additive for broilers.

Abstract
BACKGROUND Cardiovascular disease and its related deaths are increasing in the modern world. Therefore, there is a need to identify a plant based nutraceutical supplement with potent activity. HYPOTHESIS/PURPOSE Reportedly, the protective effect of the rutin in hypoxia-induced cardiomyocytes is due to the activation of molecular networks related to programmed cell death. STUDY DESIGN-METHODS Phytochemical methods and advanced analytical methods were employed to isolate natural products from Spermococe hispida their effects in cardiomyocyets. RESULTS We reports herein that CoCl2-induced hypoxic condition significantly decreased cell viability as evidenced by MTT assay and cell cycle analysis. Western blot studies revealed an up-regulation of HIF-1α, BAX and caspase and down-regulation of BCl-2 expression, followed by modulation of Akt, p-Akt, p38 and p-p38. The oxidative abnormalities were ameliorated by rutin pretreatment, as deduced by the reduced CoCl2-induced cytotoxicity, MDA concentration and LDH activity and the enhanced levels of GSH and SOD in a dose-dependent manner. Rutin protects H9c2 cells from CoCl2-induced hypoxic damage by mitigating oxidative stress and preserving cell viability by modulating the antiapoptotic proteins. CONCLUSION The overall findings reinforce the cardioprotective action of rutin, a potential source of antioxidant of natural origin, which may help in mitigating the progress of oxidative stress in hypoxic conditions such as myocardial infarction and stroke.
