Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Shaoyao Gancao Fuzi Decoction (SGFD), has been employed for thousands of years in the treatment of rheumatoid arthritis (RA) with remarkable clinical efficacy. However, the material basis underlying the effectiveness of SGFD still remains unclear. AIM OF THE REVIEW This study aims to elucidate the material basis of SGFD through the application of network pharmacology and biological affinity ultrafiltration. RESULTS UPLC-Q-TOF-MS/MS was employed to characterize the components in SGFD, the identified 145 chemical components were mainly categorized into alkaloids, flavonoids, triterpenoids, and monoterpenoids according to the structures. Network pharmacology method was utilized to identify potential targets and signaling pathways of SGFD in the RA treatment, and the anti-inflammatory and anti-RA effects of SGFD were validated through in vivo and in vitro experiments. Moreover, as the significant node in the pharmacology network, TNF-α, a classical therapeutic target in RA, was subsequent employed to screen the interacting compounds in SGFD via affinity ultrafiltration screening method, 6 active molecules (i.e.,glycyrrhizic acid, paeoniflorin, formononetin, isoliquiritigenin, benzoyl mesaconitine, and glycyrrhetinic acid) were exhibited significant interactions. Finally, the significant anti-inflammatory and anti-TNF-α effects of these compounds were validated at the cellular level. CONCLUSIONS In conclusion, this study comprehensively elucidates the pharmacodynamic material basis of SGFD, offering a practical reference model for the systematic investigation of traditional Chinese medicine formulas.

Abstract
T helper (Th) 17 cells highly contribute to the immunopathology of rheumatoid arthritis. Morin, a natural flavonoid, owns well anti-arthritic action but unclear effect on Th17 differentiation. This study tried to solve this issue and explore the mechanisms in view of cellular metabolism. Naïve CD4+ T cells were treated with anti-CD3/CD28 along with Th17-inducing cytokines. Morin was shown to block Th17 differentiation without affecting cell viability even when Foxp3 was dampened. The mechanisms were ascribed to the limited fatty acid synthesis by restricting FASN transcription, as indicated by metabolomics analysis, nile red staining, detection of triglycerides, FASN overexpression, and addition of palmitic acid. Moreover, morin had slight effect on cell apoptosis and protein palmitoylation during Th17 differentiation, but blocked the binding of RORγt to promoter and CNS2 region of Il17a gene. Oleic acid rescued the inhibition of morin on RORγt function, and Th17-inducing cytokines could not induce RORγt function in SCD1-defficient cells, suggesting that oleic acid but not palmitic acid was the direct effector in the action of morin. Then, PPARγ was identified as the target of morin, and GW9662 or PPARγ CRISPR/Cas9 KO plasmid weakened its above-mentioned effects. The transrepression of FASN by morin was owing to physical interaction between PPARγ and Sp1, and the importance of Sp1 in Th17 differentiation was confirmed by siSp1. Finally, the effects and mechanisms for morin-dampened Th17 responses were confirmed in collagen-induced arthritis (CIA) mice. Collectively, morin inhibited Th17 differentiation and alleviated CIA by limiting fatty acid synthesis subsequent to PPARγ activation.

Therapeutic targeting of Ras/Raf/MAPK pathway by natural products: A systematic and mechanistic approach for neurodegeneration. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2023; 115:154821. [PMID: 37119761 DOI: 10.1016/j.phymed.2023.154821] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/26/2022] [Revised: 04/03/2023] [Accepted: 04/11/2023] [Indexed: 05/21/2023]
Abstract
BACKGROUND Multiple dysregulated pathways are behind the pathogenesis of neurodegenerative diseases (NDDs); however, the crucial targets are still unknown. Oxidative stress, apoptosis, autophagy, and inflammation are the most dominant pathways that strongly influence neurodegeneration. In this way, targeting the Ras/Raf/mitogen-activated protein kinases (MAPKs) pathway appears to be a developing strategy for combating NDDs like Parkinson's disease, Alzheimer's disease, stroke, aging, and other NDDs. Accordingly, plant secondary metabolites have shown promising potentials for the simultaneous modulation of the Ras/Raf/MAPKs pathway and play an essential role in NDDs. MAPKs include p38 MAPK, extracellular signal-regulated kinase 1/2 (ERK 1/2), and c-Jun N-terminal kinase (JNK), which are important molecular players in neurodegeneration. Ras/Raf, which is located the upstream of MAPK pathway influences the initiation and progression of neurodegeneration and is regulated by natural products. PURPOSE Thus, the present study aimed to investigate the neuroprotective roles of plant- and marine-derived secondary metabolites against several NDDs through the modulation of the Ras/Raf/MAPK signaling pathway. STUDY DESIGN AND METHODS A systematic and comprehensive review was performed to highlight the modulatory roles of natural products on the Ras/Raf/MAPK signaling pathway in NDDs, according to the PRISMA guideline, using scholarly electronic databases, including PubMed, Scopus, and Web of Sciences. Associated reference lists were also searched for the literature review. RESULTS From a total of 1495 results, finally 107 articles were included in the present study. The results show that several natural compounds such as alkaloid, phenolic, terpenoids, and nanoformulation were shown to have modulatory effects on the Ras/Raf/MAPKs pathway. CONCLUSION Natural products are promising multi-targeted agents with on NDDs through Ras/Raf/MAPKs pathway. Nevertheless, additional and complementary studies are necessary to check its efficacy and potential side effects.

Bone-derived MSCs encapsulated in alginate hydrogel prevent collagen-induced arthritis in mice through the activation of adenosine A 2A/2B receptors in tolerogenic dendritic cells. Acta Pharm Sin B 2023; 13:2778-2794. [PMID: 37425054 PMCID: PMC10326293 DOI: 10.1016/j.apsb.2023.04.003] [Citation(s) in RCA: 8] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2023] [Revised: 03/21/2023] [Accepted: 03/27/2023] [Indexed: 07/11/2023] Open
Abstract
Tolerogenic dendritic cells (tolDCs) facilitate the suppression of autoimmune responses by differentiating regulatory T cells (Treg). The dysfunction of immunotolerance results in the development of autoimmune diseases, such as rheumatoid arthritis (RA). As multipotent progenitor cells, mesenchymal stem cells (MSCs), can regulate dendritic cells (DCs) to restore their immunosuppressive function and prevent disease development. However, the underlying mechanisms of MSCs in regulating DCs still need to be better defined. Simultaneously, the delivery system for MSCs also influences their function. Herein, MSCs are encapsulated in alginate hydrogel to improve cell survival and retention in situ, maximizing efficacy in vivo. The three-dimensional co-culture of encapsulated MSCs with DCs demonstrates that MSCs can inhibit the maturation of DCs and the secretion of pro-inflammatory cytokines. In the collagen-induced arthritis (CIA) mice model, alginate hydrogel encapsulated MSCs induce a significantly higher expression of CD39+CD73+ on MSCs. These enzymes hydrolyze ATP to adenosine and activate A2A/2B receptors on immature DCs, further promoting the phenotypic transformation of DCs to tolDCs and regulating naïve T cells to Tregs. Therefore, encapsulated MSCs obviously alleviate the inflammatory response and prevent CIA progression. This finding clarifies the mechanism of MSCs-DCs crosstalk in eliciting the immunosuppression effect and provides insights into hydrogel-promoted stem cell therapy for autoimmune diseases.

Abstract
SQSTM1/p62 sequesters intracellular aberrant proteins and mediates their selective autophagic degradation. p62 oligomerization posttranslational modification enhances its sequestration function and positively regulates the KEAP1-NRF2 redox pathway. However, the regulation of p62 covalent oligomerization has yet been poorly characterized. Here, we identified a natural small-molecule sesquiterpene, Iso-seco-tanapartholide (IST) modified p62 cysteine residues, which induced p62 to form crosslinked oligomers between TBS and TBS or TBS and PB1 domains in a covalently non-disulfide-linked manner. Using LC-MS/MS analysis and complementary approaches, we revealed that Cys residues of p62 were necessary for IST-induced covalent oligomer. This oligomerization promoted p62 recruitment of KEAP1 for degradation by autophagosomes and released NRF2 to the nucleus to activate the expression of downstream genes with anti-oxidant and anti-inflammatory capacities. Accordingly, IST-mediated p62/NRF2 activation conferred protection from oxidative and inflammatory destruction of rheumatoid arthritis in vitro and in vivo. In contrast, p62-knockdown cells displayed a reduced anti-oxidant response and increased pro-inflammatory cytokine secretion in response to TNF-α stimulation. Hence, our findings uncover an unrecognized role of IST in the regulation of p62 oligomerization and provide a new strategy for the treatment of rheumatoid arthritis.

Abstract
OBJECTIVE Rheumatoid arthritis (RA) is a chronic autoimmune inflammatory disorder of the synovial joints. Celastrol (Cel) is a quinone-methylated triterpenoid extracted from Tripterygium wilfordii Hook F (TwHF) that has been proven to be effective in treating RA. However, the underlying molecular mechanism of celastrol in the treatment of RA remains unknown. This study explored the protective effect of celastrol against RA and the specific mechanisms of celastrol in vitro and in vivo. METHODS A chicken type II collagen (CII)-induced arthritis (CIA) mouse model was used to explore the anti-arthritic effects of celastrol, and paw swelling degree, the poly-arthritis index score and serum cytokine levels were determined. Pathological morphology was observed using hematoxylin and eosin (H&E) staining. The influences of celastrol on the proliferation of tumor necrosis factor-α (TNF-α)-induced fibroblast-like synoviocytes (FLSs) were tested by Cell Counting Kit-8 (CCK-8) assays and5-ethynyl-2'-deoxyuridine (EdU) staining assays. The level of autophagy was detected by transmission electron microscopy (TEM). Furthermore, the PI3K/AKT/mTOR pathway and the status of autophagy in the CIA model and FLSs were also detected by western blot and immunofluorescence staining. RESULTS The results showed that celastrol decreased arthritis severity and inhibited TNF-α-induced FLSs proliferation. Additionally, celastrol decreased the secretion of pro-inflammatory cytokines. Moreover, celastrol increased autophagosome levels and LC3B protein expression in TNF-α-treated FLSs. Furthermore, celastrol increased the protein expression of LC3-II and Beclin-1 and decreased the phosphorylation degree of mTOR and AKT. CONCLUSION In conclusion, our findings confirmed that celastrol ameliorates RA via the up-regulation of autophagy by inhibiting the PI3K/AKT/mTOR axis.

Abstract
Heilaohu, the roots of Kadsura coccinea, has been used in Tujia ethnomedicine to treat rheumatic arthritis (RA). Heilaohuacid G (1), a new 3,4-seco-lanostane type triterpenoid isolated from the ethanol extract of Heilaohu, whose structure was determined using HR-ESI-MS data, NMR spectroscopic analyses, and ECD calculations. In this study, our purpose is to elucidate the mechanisms of Heilaohuacid G in the treatment of RA by inhibited proliferation of rheumatoid arthritis-fibroblastoid synovial (RA-FLS) cells and inhibited the inflammatory reactions in LPS-induced RA-FLS and RAW 264.7 cell lines via inhibiting NF-κB pathway. The biological activity screening experiments indicated that Heilaohuacid G significantly inhibited proliferation of RA-FLS cells with IC50 value of 8.16 ± 0.47 μM. CCK-8 assay, ELISA, flow cytometry assay, and Western blot were used to measure the changes of cell viability, apoptosis, and the release of inflammatory cytokines. Heilaohuacid G was found not only induced RA-FLS cell apoptosis, but also inhibited the inflammatory reactions in LPS-induced RA-FLS and RAW 264.7 cell lines via inhibiting NF-κB pathway. Furthermore, Heilaohuacid G (p.o.) at doses of 3.0, 6.0, and 12.0 mg/kg and the ethanol extracts of Heilaohu (p.o.) at doses of 200, 400, and 800 mg/kg both were confirmed antiinflammatory effects on xylene-induced ear mice edema model.

Metabolomics combined with network pharmacology to study the mechanism of Shentong Zhuyu decoction in the treatment of rheumatoid arthritis. JOURNAL OF ETHNOPHARMACOLOGY 2022; 285:114846. [PMID: 34826542 DOI: 10.1016/j.jep.2021.114846] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/11/2021] [Revised: 10/16/2021] [Accepted: 11/14/2021] [Indexed: 06/13/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Shentong Zhuyu decoction (STZYD) was first recorded in the classic of "Yilin Gaicuo" written by Wang Qingren, and recognized by the Chinese National Administration of Traditional Chinese Medicine as one of the 100 classic formulas. The formula has been widely used in the treatment of rheumatoid arthritis (RA) with significant clinical effects. However, its mechanism of action is not completely clear. AIM OF THE STUDY This study aimed to explore the mechanism of STZYD in the treatment of RA by network pharmacology and metabolomics. MATERIALS AND METHODS The effects of STZYD anti-RA were investigated by paw swelling, arthritis score, cytokine level, histopathological and micro-CT analysis in adjuvant-induced arthritis (AIA) rats. The chemical constituents of STZYD and absorbed constituents in AIA rat serum were analyzed by UPLC-Q-Exactive MS/MS. Based on the characterized chemical components, the network pharmacology was used to find potential targets and signaling pathways of STZYD in RA treatment. Meanwhile, the predicted pathway was determined by the Western blot (WB). Subsequently, non-targeted metabolomics of serum was performed to analyze metabolic profiles, potential biomarkers, and metabolic pathways of STZYD in the treatment of RA based on LC-MS technology. RESULTS STZYD significantly alleviated RA symptoms by improving paw redness and swelling, bone and cartilage damage, synovial hyperplasia, and infiltration of inflammatory cells, and decreased the generation of pro-inflammatory cytokines IL-1β, IL-6, IL-17A and TNF-α in AIA rats. Totally, 59 chemical components of STZYD and 24 serum migrant ingredients were identified. A total of 655 genes of potential bioactive components in STZYD and 1025 related genes of RA were obtained. TNF signaling pathway was considered to one of the main signaling pathways of STZYD anti-RA by KEGG analysis, including a wide range intracellular signaling pathways. NF-κB signaling pathway regulates inflammation and immunity in the TNF signaling pathway. STZYD markedly inhibited the expression of NF-κB signaling pathway. Ten potential biomarkers were found in metabolomics based on LC-MS technology. Alanine, aspartate and glutamate metabolism, arachidonic acid metabolism are the most related pathways of STZYD anti-RA. CONCLUSION The study based on serum pharmacochemistry, network pharmacology and metabolomics indicated that STZYD can improve RA through regulating inflammation and immunity related pathways, and provided a new possibility for treatment of RA.

Abstract
Hydrogen Sulfide (H2S) mediates biological effects in a variety of ways. Due to its strong reducing potential, H2S has been recognized to have an important role in oxidative stress induced hypoxia. It has been reported that H2S production and miRNA can mutually regulate each other. H2S is produced by the catalytic activity of cystathionine-β-synthase (CBS), which is under the regulation of miRNAs. In this study, we used target gene prediction software, and identified miR-203 as a potential regulator of CBS. We verified this finding using an oxygen and glucose deprivation (OGD) hypoxia cell model in SH-SY5Y cells and pMIR-REPORT™ luciferase miRNA expression reporter vector. Furthermore, transfecting SH-SY5Y cells with miRNA agomir (agonist) and antagomir (antagonist) by lipofectamin RNAiMAX, we further validated miR-203 as a direct regulator of CBS. We also found that miR-203 protects from cell injury by regulating lipid peroxidation, cell apoptosis, and mitochondrial membrane potential. These findings suggest that while over-expression of miR-203 can aggravate OGD induced cell injury, inhibition of miR-203 can protect against OGD induced cell injury. Based on our data and that of others, we propose that miR-203 may regulate oxidative stress induced cell injury by regulating CBS expression and adjusting the levels of H2S production.

Abstract
Rheumatoid arthritis (RA) is a highly disabling autoimmune disorder, characterized by the proliferation of Fibroblast-like Synoviocytes (FLSs). Icariin is a prenylated flavonol glycoside extracted from the medical plant Epimedium, which can inhibit the proliferation and migration of FLSs. However, the potential mechanism of icariin to alleviate RA remains unclear. In this study, icariin inhibited the migration and proliferation of FLSs in a concentration-dependent manner, by inducing G2/M phase arrest and apoptosis. Icariin reduced the mitochondrial transmembrane potential, upregulated cytosolic cytochrome c and increased the level of intracellular reactive oxygen species (ROS). In conclusion, icariin inhibited the proliferation of FLSs by interfering with the cell cycle process and inducing cell apoptosis, suggesting its potential use for the treatment of RA.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Lamiophlomisrotata (Benth.) Kudo. has been used to treat trauma bleeding, rheumatism, yellow water disease in traditional Chinese medicine. AIM The aim of this work was to evaluate the anti-rheumatoid arthritis (RA) activities and underlying mechanisms of the total iridoid glucosides (TIG) from Lamiophlomisrotata (Benth.) Kudo. METHODS The chemical constituents of TIG was analyzed by high-performance liquid chromatography (HPLC) with seven reference compounds (penstemonoside, chlorotuberside, shanzhiside methyl ester, phloyoside, 7-epliamalbide, phlorigidoside C and lamalbide). The anti-rheumatoid arthritis effects of TIG were investigated by arthritis indexes and paw swelling degrees, as well as histopathological and Micro-CT analysis in adjuvant-induced arthritis (AIA) rats. The impacts of TIG on the level of inflammatory cytokines (IL-1β, TNF-α, IL-6, IFN-γ, IL-17 and IL-10), and the regulation of OPG/RANKL/NF-κB pathways were determined by the ELISA and western blot, respectively. RESULTS TIG significantly reduced the arthritis indexes and paws swelling in AIA rats, attenuated the inflammation and bone destruction in joint tissues, reduced the generation of pro-inflammatory cytokines IL-1β, TNF-α, IL-6, IFN-γ and IL-17, as well as increased the generation of anti-inflammatory cytokine IL-10 in serum. Moreover, TIG markedly inhibited the expression of p-IKK-α, p-IκB and p-p65, and decreased the ratio of OPG/RANKL in the synovial tissues. CONCLUSION TIG possessed significant anti-RA activities on adjuvant-induced arthritis, which might be ascribed to the regulation of inflammatory cytokines IL-1β, TNF-α, IL-6, IFN-γ IL-17 and IL-10, as well as inhibition of OPG/RANKL/NF-κB signaling pathways.

Abstract
BACKGROUND TLRs are some of the actively pursued drug-targets in immune disorders. Owing to a recent surge in the cognizance of TLR structural biology and signalling pathways, numerous therapeutic modulators, ranging from low-molecular-weight organic compounds to polypeptides and nucleic acid agents have been developed. METHODS A penetratin-conjugated small peptide (TIP3), derived from the core β-sheet of TIRAP, was evaluated in vitro by monitoring the TLR-mediated cytokine induction and quantifying the protein expression using western blot. The therapeutic potential of TIP3 was further evaluated in TLR-dependent in vivo disease models. FINDINGS TIP3 blocks the TLR4-mediated cytokine production through both the MyD88- and TRIF-dependent pathways. A similar inhibitory-effect was exhibited for TLR3 but not on other TLRs. A profound therapeutic effect was observed in vivo, where TIP3 successfully alleviated the inflammatory response in mice model of collagen-induced arthritis and ameliorated the disease symptoms in psoriasis and SLE models. INTERPRETATION Our data suggest that TIP3 may be a potential lead candidate for the development of effective therapeutics against TLR-mediated autoimmune disorders.

Abstract
Leonurine, also named SCM-198, which was extracted from Herba leonuri, displayed a protective effect on various cardiovascular and brain diseases, like ischemic stroke. Ischemic stroke which is the leading cause of morbidity and mortality, ultimately caused irreversible neuron damage. This study is aimed at exploring the possible therapeutic potential of SCM-198 in the protection against postischemic neuronal injury and possible underlying mechanisms. A transient middle cerebral artery occlusion (tMCAO) rat model was utilized to measure the protective effect of SCM-198 on neurons. TEM was used to determine neuron ultrastructural changes. The brain slices were stained with Nissl staining solution for Nissl bodies. Fluoro-Jade B (FJB) was used for staining the degenerating neurons. In the oxygen-glucose deprivation and re-oxygenation (OGD/R) model of bEnd.3 cells treated with SCM-198 (0.1, 1, 10 μM). Then, the bEnd.3 cells were cocultured with SH-SY5Y cells. Cell viability, MDA level, CAT activity, and apoptosis were examined to evaluate the cytotoxicity of these treatments. Western blot and immunofluorescent assays were used to examine the expression of protein related to the p-STAT3/NOX4/Bcl-2 signaling pathway. Coimmunoprecipitation was performed to determine the interaction between p-STAT3 and NOX4. In the transient middle cerebral artery occlusion (tMCAO) rat model, we found that treatment with SCM-198 could ameliorate neuron morphology and reduce the degenerating cell and neuron loss. In the in vitro model of bEnd.3 cell oxygen-glucose deprivation and reoxygenation (OGD/R), treatment with SCM-198 restored the activity of catalase (CAT), improved the expression of Cu-Zn superoxide dismutase (SOD1), and decreased the malondialdehyde (MDA) production. SCM-198 treatment prevented OGD/R-induced cell apoptosis as indicated by increased cell viability and decreased the number of TUNEL-positive cells, accompanied with upregulation of Bcl-2 and Bcl-xl protein and downregulation Bax protein. The results were consistent with SH-SY5Y cells which coculture with bEnd.3 cells. The forthcoming study revealed that SCM-198 activated the p-STAT3/NOX4/Bcl-2 signaling pathway. All the data indicated that SCM-198 protected against oxidative stress and neuronal damage in in vivo and in vitro injury models via the p-STAT3/NOX4/Bcl-2 signaling pathway. Our results suggested that SCM-198 could be the potential drug for neuroprotective effect through stabilizing endothelial cell function.

Abstract
BACKGROUND Genkwanin is a flavone isolated from the traditional Chinese herb Daphne genkwa. Our previous work proved that four flavonoids (including genkwanin) isolated from D. genkwa (FFD) significantly improved the symptoms of arthritis in rat models. Recent studies have revealed that genkwanin exhibited anti-inflammatory and immunomodulatory activities, both of which were closely related to the pathology of rheumatoid arthritis (RA). Therefore, studying the anti-RA effects and mechanisms of genkwanin may give us insight into FFD's therapeutic effects on RA. PURPOSE This study aimed to investigate the anti-rheumatoid arthritis activity of genkwanin on adjuvant-induced arthritis (AIA) model in rats and explore the underlying mechanisms. METHODS The anti-rheumatoid arthritis activity of genkwanin was evaluated on AIA rat model by determining the paw swelling degrees and arthritis index scores, along with histopathological analysis of joint tissues. The serum cytokine levels were measured by ELISA method, and serum NO levels were measured by Griess method. The expression and phosphorylation levels of proteins in JAK/STAT and NF-κB signaling pathways were determined by western blot analysis and immunohistochemistry analysis. RESULTS Genkwanin significantly decreased the paw swelling and arthritis index in AIA rats and also decreased the inflammation and bone destruction in joint tissues. The serum TNF-α, IL-6, and NO concentrations were markedly reduced while the IL-10 concentration was markedly increased with the treatment of genkwanin. Genkwanin inhibited the activation of JAK/STAT and NF-κB signaling pathways in synovial tissues of AIA rats. CONCLUSION Genkwanin exerted anti-rheumatoid arthritis effects on AIA rats through inhibiting the activation of JAK/STAT and NF-κB signaling pathways. The results obtained in this work lead us to suggest that Genkwanin could play a crucial role on the previously demonstrated anti-rheumatoid arthritis activity of flavonoid extract of D. genkwa (namely FFD).

Abstract
Rheumatoid arthritis (RA) is characterized by chronic inflammatory synovitis resulting in progressive joint destruction. Persistent synovial inflammation is induced by activation of various inflammatory cells. G-protein-coupled bile acid receptor 1 (TGR5) is a G-protein-coupled receptor activated by various bile acids, which has been reported to act as a key adaptor in regulating various signaling pathways involved in inflammatory responses and a diverse array of physiological processes, including bile acid synthesis, lipid and carbohydrate metabolism, carcinogenesis, immunity and inflammation. In the present study, TGR5 expression was detected in RA peripheral blood mononuclear cells (PBMCs), and its association with clinical disease activity, histological synovitis severity and radiological joint destruction was analyzed. Subsequently, the role and potential underlying mechanisms of TGR5 in the PBMCs of patients with RA and mice with collagen II-induced arthritis (CIA) were investigated. PBMCs were obtained from 50 patients with RA and 40 healthy controls (HCs). The mRNA and protein expression levels of TGR5 were detected in PBMCs via reverse transcription-quantitative polymerase chain reaction (RT-qPCR) and immunofluorescence staining, respectively. Additionally, the levels of proinflammatory cytokines were analyzed by RT-qPCR and enzyme-linked immunosorbent assay (ELISA). The activation of nuclear factor-κB (NF-κB) and IκB kinase a was determined via western blot analysis. The anti-arthritic and anti-inflammatory effects of LCA on mice with CIA were then investigated. The arthritis score was assessed, and the protein levels of proinflammatory cytokines in the plasma of mice were detected via ELISA. TGR5 mRNA expression was significantly downregulated in the PBMCs of patients with RA compared with in those of the HCs (0.53±0.58 for patients vs. 1.49±0.83 for HCs; P<0.001); similar findings were observed at the protein level. The mRNA expression levels of TGR5 in the PBMCs of patients with RA with a high 28-Joint Disease Activity Score (DAS28) were significantly decreased compared with in patients with a low DAS28 (0.81±0.65 for low score vs. 0.35±0.46 for high score; P=0.002). Furthermore, TGR5 expression was significantly correlated with the levels of C-reactive protein (r=−0.429; P=0.002) and the DAS28 (r=−0.383; P=0.006). RT-qPCR and ELISA analyses indicated that lithocholic acid (LCA, 10 mg/kg/day) attenuated lipopolysaccharide-induced proinflammatory cytokine production via inhibition of NF-κB activity in the PBMCs of patients with RA. In addition, the arthritis score was significantly decreased in LCA-treated CIA mice compared with in non-treated CIA mice. The increased production of tumor necrosis factor-α, interleukin (IL)-1β, IL-6 and IL-8 was significantly reduced in the plasma of LCA-treated CIA mice compared with the control. In conclusion, TGR5 may contribute to the inflammation of PBMCs in patients with RA and mice with CIA.

Abstract
Objectives: The discovery of alternative and well-tolerated anti-arthritic drugs, especially from natural products, is becoming an area of active research. Pedunculoside (PE) is a novel triterpene saponin extracted from the dried bark of Ilex rotunda Thunb. Limited published papers have reported its pharmacological properties, including anti-inflammatory, anti-myocardial ischaemia, anti-liver injury, and hypocholesterolaemic activities. However, the effect of PE on rheumatoid arthritis (RA) remains unknown. Here, we investigated the anti-arthritic effect of PE in both in vitro and in vivo models. Method: The inhibitory effects of PE on proliferation, migration, and production of inflammatory mediators in primary fibroblast-like synoviocytes (FLSs) were examined by a 5-ethynyl-2'-deoxyuridine incorporation assay, wound-healing assay, and real-time polymerase chain reaction, respectively. Cellular signalling mechanisms were analysed by Western blot. The in vivo studies were performed using a collagen-induced arthritis (CIA) rat model. Multiple methods, including arthritis scoring, enzyme-linked immunoassay, radiography, and histopathological assessment, were used to evaluate the therapeutic effects of PE on CIA rats. Results: The in vitro studies revealed that PE significantly inhibited proliferation and migration of FLSs. PE also decreased the production of pro-inflammatory cytokines, including interleukin-1β (IL-1β), IL-6, IL-8, and tumour necrosis factor-α (TNF-α). Western blot results suggested that PE suppressed TNF-α-stimulated activation of p38 and extracellular signal-regulated kinase. The in vivo studies showed that PE treatment significantly inhibited synovial inflammation and bone destruction in CIA rats. Conclusion: These results demonstrate that PE exerts an inhibitory role in FLSs and CIA rats, and therefore may have therapeutic value for the treatment of RA.

A cell-penetrating peptide blocks Toll-like receptor-mediated downstream signaling and ameliorates autoimmune and inflammatory diseases in mice. Exp Mol Med 2019; 51:1-19. [PMID: 31028244 PMCID: PMC6486608 DOI: 10.1038/s12276-019-0244-0] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2019] [Accepted: 02/11/2019] [Indexed: 12/15/2022] Open
Abstract
Toll-like receptors (TLRs) recognize pathogen/damage-associated molecular patterns and initiate inflammatory signaling cascades. Occasionally, overexpression of TLRs leads to the onset of numerous inflammatory diseases, necessitating the development of selective inhibitors to allow a protective yet balanced immune response. Here, we demonstrate that a novel peptide (TIP1) derived from Toll/interleukin-1 receptor (TIR) domain-containing adapter protein inhibited multiple TLR signaling pathways (MyD88-dependent and MyD88-independent) in murine and human cell lines. TIP1 also inhibited NLRP3-mediated IL-1β secretion, as we validated at both the protein and mRNA levels. Biophysical experiments confirmed that TIP1 specifically binds to the BB loop of the TLR4-TIR domain. Animal studies revealed that TIP1 inhibited the secretion of lipopolysaccharide (LPS)-induced proinflammatory cytokines in collagen-induced arthritis (CIA) and kaolin/carrageenan-induced arthritis (K/C) rodent models. TIP1 also rescued animals from sepsis and from LPS-induced kidney/liver damage. Importantly, TIP1 ameliorated the symptoms of rheumatoid arthritis in CIA and K/C rodent models, suggesting that TIP1 has therapeutic potential for the treatment of TLR-mediated autoimmune/inflammatory diseases.

Br J Pharmacol 2019; 176:400-415. [PMID: 30414381 PMCID: PMC6329622 DOI: 10.1111/bph.14537] [Citation(s) in RCA: 38] [Impact Index Per Article: 7.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2017] [Revised: 08/16/2018] [Accepted: 08/22/2018] [Indexed: 12/19/2022] Open
Abstract
BACKGROUND AND PURPOSE Ischaemic stroke is a leading cause of death and long-term disability. Promising neuroprotective compounds are urgently needed to overcome clinical therapeutic limitations. Neuroprotective agents are limited to single-target agents, which further limit their clinical effectiveness. Due to the brain's particular energy requirements, the energy micro-environment, centred in mitochondria, is a new research hotspot in the complex pathology of ischaemic stroke. Here, we studied the effects of neferine (Nef), a bis-benzylisoquinoline alkaloid extracted from the seed embryo of Nelumbo nucifera Gaertn, on ischaemic stroke and its underlying mitochondrial protective mechanisms. EXPERIMENTAL APPROACH Rats with permanent middle cerebral artery occlusion (pMCAO)-induced focal cerebral ischaemia and tert-butyl hydroperoxide (t-BHP)-injured PC12 cells were used to investigate the neuroprotective effects of Nef, particularly with regard to energy micro-environment regulation by mitochondria and its mechanism in vivo and in vitro. KEY RESULTS Nef protected t-BHP-injured PC12 cells in vitro and ameliorated neurological score, infarct volume, regional cerebral blood flow, cerebral microstructure and oxidant-related enzyme deficits in pMCAO rats in vivo. Nef also prevented mitochondrial dysfunction both in vivo and in vitro. The underlying mechanism of the mitochondrial protective effect of Nef might be attributed to the increased translocation of Nrf2 to the nucleus. Furthermore, the translocation of Nrf2 to nucleus was also decreased by sequestosome 1 (p62) knockdown. CONCLUSIONS AND IMPLICATIONS Our results demonstrated that Nef might have therapeutic potential for ischaemic stroke and may exert its protective role through mitochondrial protection. This protection might be attributed to the modulation of Nrf2 signalling.

Abstract
Dihydromyricetin (DMY), the main flavonoid of Ampelopsis grossedentata, has potent anti-inflammatory activity. However, the effect of DMY on chronic autoimmune arthritis remains undefined. In this study, we investigated the therapeutic effects of DMY on collagen-induced arthritis (CIA). Wistar rats were immunized with bovine type II collagen to establish CIA and were then administered DMY intraperitoneally (5, 25, and 50 mg/kg) every other day for 5 weeks. Paw swelling, clinical scoring, and histologic analysis were assessed to determine the therapeutic effects of DMY on the development of arthritis in CIA rats. The results showed that treatment with DMY significantly reduced erythema and swelling in the paws of CIA rats. Pathologic analysis of the knee joints and peripheral blood cytokine assay results confirmed the antiarthritic effects of DMY on synovitis and inflammation. Fibroblast-like synoviocytes (FLSs) were isolated from the synovium of CIA rats and treated with 10 ng/ml interleukin (IL)-1β DMY significantly inhibited the proliferation, migration, and inflammation of IL-1β-induced FLSs, whereas it significantly increased IL-1β-induced FLS apoptosis in a dose-dependent manner (6.25-25 μM). Moreover, DMY suppressed phosphorylation of IκB kinase (IKK) and inhibitor of NF-κB α and subsequently reduced the IL-1β-induced nucleus translocation of NF-κB in FLSs. Through a molecular docking assay, we demonstrated that DMY could directly bind to the Thr9 and Asp88 residues in IKKα and the Asp95, Asn142, and Gln167 residues in IKKβ These findings demonstrate that DMY could alleviate inflammation in CIA rats and attenuate IL-1β-induced activities in FLSs through suppression of NF-κB signaling.

Abstract
A series of azocompounds containing methyl salicylate 4a–k and 1-naphthyl moiety 6–8 was synthesized and tested as anticancer agents. Nitrosation of methyl 5-amino-2-hydroxybenzoate or 1-aminonaphthalene by using NaNO2 in the presence of HCl afforded diazonium salt derivatives 2 and 5, which were treated with substituted imino or substituted amino derivatives, to give the corresponding substituted amino-pent-2-en-3-yl-diazenylbenzoate 4a–k or 2-substituted-1-(naphthalen-1-yl)diazene derivatives 6a–h, 7a,b, and 8a,b. All the synthesized compounds were elucidated by elemental analysis and spectroscopic evidence.

Abstract
Imbalance of Treg/Th17 and chronic synovitis characterized by the recruitment and infiltration of inflammatory cells are the typical features of rheumatoid arthritis (RA). IL-6 promotes the differentiation and function of Th17 cells, which contributes to the imbalance of Treg/Th17 and aggravates lymphocytic infiltration in joints. DC32, a dihydroartemisinin derivative, was found to have anti-inflammatory and immunosuppressive activities in previous study. The aim of this study is to evaluate the effects and mechanisms of DC32 in immunodeficiency and inflammatory infiltration of RA. In vivo, the antirheumatic effect of DC32 was evaluated in a collagen-induced arthritis (CIA) mouse model in DBA/1 mice. The percentages of Treg and Th17 and transcription of IL-6 in the spleen were assayed. In vitro, a coculture system of ConA-activated lymphocytes and fibroblast-like synoviocytes (FLSs) from rat with adjuvant arthritis (AA) was established. The effects and mechanisms of DC32 on synovitis were investigated. It was shown that DC32 inhibited footpad swelling and lymphocytic infiltration in mice with CIA and significantly restored the Treg/Th17 balance by reducing the transcription of IL-6 in splenocytes. DC32 significantly inhibited the lymphocyte-induced invasion and migration of FLSs by decreasing the secretion of MMPs (MMP-2, MMP-3) in vitro. DC32 also reduced the transcription of chemokines (CXCL12, CX3CL1) and IL-6 in FLSs, as well as IL-6 levels in the supernatant. These results demonstrated that DC32 may attenuate RA by restoring Treg/Th17 balance and inhibiting lymphocytic infiltration through downregulation of the expression and transcription of IL-6. This study supports the potential of DC32 to down-regulate IL-6 for the treatment of RA and other related autoimmune diseases.

Abstract
Jatrorrhizine hydrochloride (JH), an active component isolated from the traditional Chinese herb Coptis chinensis, has been reported to have antimicrobial, antitumor, antihypercholesterolemic, and neuroprotective activities. However, its antirheumatoid arthritis (RA) property remains unknown. In this study, a collagen-induced arthritis (CIA) rat model was used to evaluate the therapeutic effects of JH on RA by using arthritis score, radiological evaluation, and histopathological assessment. The in vitro effects of JH on proliferation, migration, and production of inflammatory mediators in RA-derived fibroblast-like synoviocyte MH7A cells were determined by the EdU incorporation assay, wound healing assay, real-time PCR, and ELISA, respectively. The in vivo studies showed that JH treatment significantly prevented the progression and development of RA in CIA rats through anti-inflammation and suppressing bone destruction. The in vitro studies revealed that JH could effectively attenuate the destructive phenotypes of MH7A cells, including inhibiting proliferation, migration, and production of inflammatory mediators. Further mechanistic analysis demonstrated that JH suppressed tumor necrosis factor alpha (TNFα)-stimulated activations of nuclear factor of kappaB (NF-κB) and mitogen-activated protein kinases (MAPKs) (ERK and p38) leading to the downregulation of proinflammatory cytokines, which might be beneficial to the antiproliferative and antimigratory activities of FLS cells. Collectively, our results demonstrated that JH has a great potential to be developed into a novel therapeutic agent for treating RA.

Abstract
Neuroinflammatory reactions mediated by microglia and astrocytes have been shown to play a key role in early progression of Alzheimer’s disease (AD). Increased evidences have demonstrated that neurons exacerbate local inflammatory reactions by producing inflammatory mediators and act as an important participant in the pathogenesis of AD. Methyl salicylate lactoside (MSL) is an isolated natural product that is part of a class of novel non-steroidal anti-inflammatory drugs (NSAID). In our previous studies, we demonstrated that MSL exhibited therapeutic effects on arthritis-induced mice and suppressed the activation of glial cells. In the current study, we investigated the effects of MSL on cognitive function and neuronal protection induced by amyloid-beta peptides (Aβ) and explored potential underlying mechanisms involved. Amyloid precursor protein (APP) and presenilin 1 (PS1) double transgenic mice were used to evaluate the effects of MSL through behavioral testing and neuronal degenerative changes. In addition, copper-injured APP Swedish mutation overexpressing SH-SY5Y cells were used to determine the transduction of cyclooxygenase (COX) and mitogen-activated protein kinase (MAPK) pathways. Our results indicated that at an early stage, MSL treatment ameliorated cognitive impairment and neurodegeneration in APP/PS1 mice. Moreover, in an in vitro AD model, MSL treatment protected injured cells by increasing cell viability, improving mitochondrial dysfunction, and decreasing oxidative damage. In addition, MSL inhibited the phosphorylated level of c-Jun N-terminal kinase (JNK) and p38 MAPK, and suppressed the expression of COX-1/2. As a novel NSAIDs and used for the treatment in early stage of AD, MSL clearly demonstrated cognitive preservation by protecting neurons via a pleiotropic anti-inflammatory effect in the context of AD-associated deficits. Therefore, early treatment of anti-inflammatory therapy may be an effective strategy for treating AD.

[PMID: 29425654 DOI: 10.1016/j.phymed.2017.10.016] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/17/2017] [Revised: 09/08/2017] [Accepted: 10/24/2017] [Indexed: 06/08/2023]
Abstract
BACKGROUND Blocking the formation and invasive growth of pannus and its secretion of inflammatory cytokines and MMPs is important for treating rheumatoid arthritis. HYPOTHESIS/PURPOSE Anti-arthritic activity of Aralia continentalis Kitag., an oriental herbal medicine, and the underlying mechanisms involved were investigated. STUDY DESIGN Anti-inflammatory and anti-nocicpetive activities of the ethanolic extract (50% v/v) of Aralia continentalis Kitag. harvested from Imsil, Korea (ACI) were investigated in IL-1β-stimulated human fibroblast-like synoviocyte (FLS) cells and rodent models of collagen-induced polyarthritis and carrageenan-induced acute paw pain. METHODS In IL-1β-stimulated FLS cells derived from rheumatoid arthritis patients, the anti-inflammatory activity of ACI was examined by analyzing the expression levels of inflammatory mediators such as TNF-α, IL-6, IL-8, MMP-1, MMP-3, MMP-13, PGE2, and COX-2 using ELISA and RT-PCR analysis. The anti-arthritic activity of ACI was investigated by measuring body weight, squeaking score, paw volume, and arthritis index in collagen-induced polyarthritis mice. The anti-nociceptive activity of ACI was examined in the paw-pressure test and Tail-flick latency test in rats. RESULTS The ethanolic extract (50% v/v) of ACI reduced the levels of TNF-α, IL-6, IL-8, MMP-1, and MMP-13 secreted by IL-1β-stimulated FLS cells, whereas MMP-3, COX-2, and PGE2 were not significantly affected. ACI inhibited the migration of NF-κB into the nucleus through the inhibition of ERK- and JNK-dependent MAP kinase pathways in IL-1β-stimulated FLS cells. In collagen-induced polyarthritis mice, oral administration of ACI extract (200 mg/kg) significantly alleviated arthritic behaviors. Histological observations of arthritic mouse knees were consistent with their behaviors. The anti-arthritic and anti-inflammatory activities of 200 mg/kg ACI extract were comparable to those of 10 mg/kg prednisolone when administered to mice. However, ACI administration did not significantly affect carrageenan-induced hyperalgesia or thermal nociception in rats. CONCLUSION These results suggest that the ethanolic extract of ACI have significant anti-inflammatory and anti-arthritic effects in a rodent arthritis model and in IL-1β-stimulated FLS cells. Thus, ACI may be a useful candidate for developing pharmaceuticals or dietary supplements for the treatment of inflammatory arthritis.

Abstract
Background: Tamarixinin A, a natural tannin isolated from Myricaria bracteata, has been confirmed to have moderate anti-inflammatory effects in vitro and in vivo. However, how it effects rheumatoid arthritis (RA) is still unknown. Therefore, the aim of this study is to investigate the therapeutic effects of tamarixinin A on experimental RA, and explore the underlying mechanism. Methods: The anti-arthritic effects of tamarixinin A were evaluated on collagen-induced arthritis (CIA) mice and adjuvant-induced arthritis (AIA) rats. The hind paw thickness, inflammatory cytokine levels in serum, and histopathological assessments were determined. The arthritis score was evaluated. Activation of p38 and p65 in AIA rats was also determined. The anti-inflammatory effect in vitro was also tested in LPS induced macrophages, and its related anti-inflammatory signaling pathways were explored. Results: Treatment with tamarixinin A significantly suppressed the progression and development of RA in CIA mice and AIA rats. Both in CIA mice and AIA rats, arthritis scores decreased, paw swelling and thickness were reduced, and joint destruction was alleviated. In AIA rats, tamarixinin A significantly inhibited the expression of p38, p-p38 and p65. In addition, tamarixinin A inhibited the production of pro-inflammatory mediators, the phosphorylation of p38, ERK, JNK and p65, as well as the nuclear translocation of p38 in LPS- induced macrophages. Conclusion: Tamarixinin A is a potential effective candidate compound for human RA treatment, which executes anti-arthritic effects potentially through down-regulating MAPK and NF-κB signal pathway activation.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Bergenin, an active constituent of the plants of the genus Bergenia, was reported to have anti-inflammatory effects in the treatment of chronic bronchitis and chronic gastritis clinically. However, its therapeutic effect on lipopolysaccharide (LPS)-induced acute lung injury (ALI) and its potential mechanisms of actions were still unknown. AIM OF THIS STUDY To evaluate the effect of bergenin on murine model of acute lung injury induced by LPS and also to explore its potential mechanisms. MATERIALS AND METHODS Half an hour and 12h after an intranasal inhalation of LPS, male BALB/c mice were treated with bergenin (50,100 and 200mg/kg) or dexamethasone (DEX, 5mg/kg) by gavage. Twenty-four hours after LPS exposure, the lung wet/dry ratio, histological changes, myeloperoxidase (MPO) in lung tissues, inflammatory cells (in BALF) and cytokines (in BALF and serum) were detected. Meanwhile, the protein expression of MyD88 and the phosphorylation of NF-κB p65 in lung tissue were analyzed using immunoblot analysis. Moreover, the nuclear translocation and the phosphorylation of NF-κB p65 in Raw264.7 cells were also analyzed. The viability of Raw264.7 cells was determined by MTT assay. RESULTS Results showed that bergenin significantly decreased pulmonary edema, improved histological changes and reduced MPO activity in lung tissues. Moreover, bergenin obviously decreased inflammatory cells, IL-1β and IL-6 production in BALF, as well as IL-1β, TNF-α and IL-6 production in serum of LPS-induced ALI mice. Furthermore, bergenin markedly inhibited LPS-induced NF-κB p65 phosphorylation, as well as the expression of MyD88 but not the expression of NF-κB p65 in lung tissues. Additionally, bergenin also significantly inhibited the nuclear translocation and the phosphorylation of NF-κB p65 stimulated by LPS in Raw264.7 cells. CONCLUSIONS These findings suggested that bergenin had a therapeutic effect on LPS-induced ALI by inhibiting NF-κB activition.

Int J Mol Med 2016; 39:307-316. [PMID: 28035365 PMCID: PMC5358712 DOI: 10.3892/ijmm.2016.2843] [Citation(s) in RCA: 35] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2016] [Accepted: 11/20/2016] [Indexed: 12/29/2022] Open
Abstract
The induction of apoptosis-resistant rheumatoid synovial tissue cells has been related to constitutively active Janus kinase/signal transducers and activators of transcription (JAK/STAT) signaling in rheumatoid arthritis (RA). The excessive proliferation and inherent resistance to apoptosis of fibroblast-like synoviocytes (FLS) is an important mechanism by which RA originates. However, the effects of matrine on FLS in RA is unclear. The present study aimed to investigate the mechanism of action of matrine in a rat model of collagen-induced arthritis (CIA). The CIA model was established using bovine type II collagen. FLS were isolated from control and CIA rats, cultured in vitro, and confirmed to harbor fibroblast-like characteristics. After treatment of FLS with varying concentrations of matrine, the JAK2 inhibitor AG490, or a combination of both drugs, cell proliferation, apoptosis rate, expression of apoptotic markers and the activation of the JAK/STAT pathway were assessed. Additionally, CIA rats were administered either matrine or methotrexate by oral gavage to examine the effects of therapeutic intervention on arthritis pathogenesis. The arthritis index (AI) was measured and ankle joint structure was analyzed histologically to determine the severity of CIA. Furthermore, expression levels of apoptotic markers and members of the JAK/STAT family were also examined in vivo. Compared with the CIA group, matrine reduced AI and improved ankle pathology. Matrine also inhibited FLS proliferation, induced G0/G1 cell cycle arrest, and increased the rate of apoptosis in vitro. The effects of matrine on apoptosis induction were further confirmed by observations that Bcl-2 levels were decreased, whereas Bax and caspase-3 levels were increased in the matrine-treated synovial tissues and FLS. Finally, matrine treatment also diminished the phosphorylation, and hence activation of JAK2, STAT1 and STAT3. Our results suggest that matrine induces the apop-tosis of FLS from rats with CIA by inhibiting activation of the JAK/STAT signaling pathway.

A betulinic acid derivative SH479 inhibits collagen-induced arthritis by modulating T cell differentiation and cytokine balance. Biochem Pharmacol 2016; 126:69-78.

Abstract
The ideal therapeutic drug for rheumatoid arthritis (RA) should not only inhibit inflammation, but also prevent articular joint damage and particularly inhibit osteoclastogenesis. Betulinic acid (BA) is a natural pentacyclic triterpene that has displayed moderate anti-inflammatory and anti-osteoclastogenesis activities in various experimental systems, suggesting that BA or its derivatives could have an inhibitory effect on RA. In this study, we screened BA derivatives and found a heterocyclic ring-fused BA derivative, SH479, which had greater inhibitory effect than BA on Th17 differentiation. Moreover, we investigated the immune regulatory activity and potential therapeutic effects of SH479 in an experimental model of rheumatoid arthritis, the collagen-induced arthritis (CIA) mouse model. SH479 significantly inhibited Th1 and Th17 polarization, antigen-specific T cell proliferation and splenic lymphocyte-induced osteoclastogenesis. Furthermore, it diminished arthritis scores as well as bone destruction and cartilage depletion in the CIA mouse model. The protective effect of SH479 was accompanied by decreased levels of pro-inflammatory cytokines IL-17 and IFN-γ, together with enhanced anti-inflammatory cytokine expression including IL-10 and IL-4, as well as elevated CD4+ Foxp3+ cell number. At the molecular level, our results indicated that SH479 alleviated CIA through regulation of CD4+ T cell subtypes by JAK-STAT pathways. In conclusion, this study demonstrates that SH479 has therapeutic potential for rheumatoid arthritis through an anti-inflammatory effect by shifting a pathogenic Th17/Th1 response to a Th2/Treg phenotype, and also through an additional articular bone protection effect.

Abstract
In this study, a new series of 16 methyl salicylate derivatives bearing a piperazine moiety were synthesized and characterized. The in vivo anti-inflammatory activities of target compounds were investigated against xylol-induced ear edema and carrageenan-induced paw edema in mice. The results showed that all synthesized compounds exhibited potent anti-inflammatory activities. Especially, the anti-inflammatory activities of compounds M15 and M16 were higher than that of aspirin and even equal to that of indomethacin at the same dose. In addition, the in vitro cytotoxicity activities and anti-inflammatory activities of four target compounds were performed in RAW264.7 macrophages, and compound M16 was found to significantly inhibit the release of lipopolysaccharide (LPS)-induced interleukin (IL)-6 and tumor necrosis factor (TNF)-α in a dose-dependent manner. In addition, compound M16 was found to attenuate LPS induced cyclooxygenase (COX)-2 up-regulation. The current preliminary study may provide information for the development of new and safe anti-inflammatory agents.

Abstract
Secondary lymphedema is a common complication of cancer treatment characterized by chronic limb swelling with interstitial inflammation. The rodent hindlimb is a widely used model for the evaluation of novel lymphedema treatments. However, the assessment of limb volume in small animals is challenging. Recently, high-resolution three-dimensional (3D) imaging modalities have been introduced for rodent limb volumetry. In the present study we evaluated the validity of microcomputed tomography (μCT), magnetic resonance imaging (MRI) and ultrasound in comparison to conventional measuring techniques. For this purpose, acute lymphedema was induced in the mouse hindlimb by a modified popliteal lymphadenectomy. The 4-week course of this type of lymphedema was first assessed in 6 animals. In additional 12 animals, limb volumes were analyzed by μCT, 9.4 T MRI and 30 MHz ultrasound as well as by planimetry, circumferential length and paw thickness measurements. Interobserver correlation was high for all modalities, in particular for μCT analysis (r = 0.975, p < 0.001). Importantly, caliper-measured paw thickness correlated well with μCT (r = 0.861), MRI (r = 0.821) and ultrasound (r = 0.800). Because the assessment of paw thickness represents a time- and cost-effective approach, it may be ideally suited for the quantification of rodent hindlimb lymphedema.

Abstract
Systemic lupus erythematosus (SLE), with a high incidence rate and insufficient therapy worldwide, is a complex disease involving multiple organs characterized primarily by inflammation due to deposition of immunocomplexes formed by production of autoantibodies. The mechanism of SLE remains unclear, and the disease still cannot be cured. We used pristane to induce SLE in female BALB/c mice. Methyl salicylate 2-O-β-d-lactoside (MSL; 200, 400, and 800 mg/kg) was orally administered 45 days after pristane injection for 4.5 months. The results showed that MSL antagonized the increasing levels of multiple types of antibodies and cytokines in lupus mice. MSL was found to suppress joint swelling and have potent inhibitory effect on arthritis-like symptoms. MSL also significantly decreased the spleen index and expression of inflammatory markers in the lupus mice. MSL protected the kidneys of lupus mice from injury through inhibiting the expression of inflammatory cytokines and reducing the IgG and C3 immunocomplex deposits. Further Western blot assays revealed that the downregulation of the intracellular inflammatory signals of NFκB and JAK/STAT3 might be the potential molecular mechanisms of the pharmacological activity of MSL against SLE in vivo. These findings may demonstrate that MSL has the potential to be a useful and highly effective treatment for SLE.

[PMID: 26936538 DOI: 10.3892/mmr.2016.4923] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2015] [Accepted: 01/14/2016] [Indexed: 11/06/2022] Open
Abstract
The aim of the current study was to investigate the effects of Astragaloside‑IV (AS‑IV) on inflammatory mediators in synoviocytes and collagen‑induced arthritic rats. Synoviocytes were stimulated with lipopolysaccharides (LPS) and Sprague‑Dawley rats were injected with type II collagen. AS‑IV was administered to the LPS‑stimulated synoviocytes and collagen‑induced arthritis (CIA) rats. The inflammation of LPS‑stimulated synoviocytes and CIA rats was assessed using enzyme‑linked immunosorbent assays and western blotting. Using Cell Counting Kit‑8 analysis, it was demonstrated that AS‑IV (5, 20 and 50 mg/ml) inhibited the LPS‑stimulated synoviocytes proliferation in a dose‑dependent manner. AS‑IV significantly inhibited the LPS‑stimulated inflammatory response, as indicated by the expression levels of TNF‑α, IL‑1β, IL‑6 and IL‑8. In addition, treatment with AS‑IV significantly reduced the LPS‑stimulated cyclooxygenase (COX)‑1, COX‑2, high mobility group box 1 protein (HMGB1) and intercellular adhesion molecule 1 overexpression, and intranuclear nuclear factor (NF)‑κBp65 subunit accumulation and activation of c‑Jun N‑terminal kinase (JNK)1/2 and p38. Similar to the protective effects of AS‑IV on LPS‑stimulated synoviocytes, AS‑IV treatment significantly reduced the expression levels of tumor necrosis factor α, interleukin (IL)‑1β, IL‑6 and IL‑8 expression levels, and attenuated intranuclear NF‑κBp65 subunit accumulation and overexpression of COX‑2 and inducible nitric oxide synthase in CIA rats. In conclusion, the results of the present study demonstrated for the first time, to the best of our knowledge, that AS‑IV protects synoviocytes against LPS‑ and collagen‑induced inflammatory responses through inhibition of the HMGB1‑dependent JNK1/2‑ and p38‑activated NF‑κB/COX‑2 pathway.

Abstract
Neocryptotanshinone (NCTS) is a natural product isolated from traditional Chinese herb Salvia miltiorrhiza Bunge. In this study, we investigated its anti-inflammatory effects in lipopolysaccharide (LPS)-stimulated mouse macrophage (RAW264.7) cells. MTT results showed that NCTS partly reversed LPS-induced cytotoxicity. Real-time PCR results showed that NCTS suppressed LPS-induced mRNA expression of inflammatory cytokines, including tumor necrosis factor α (TNFα), interleukin-6 (IL-6) and interleukin-1β (IL-1β). Moreover, NCTS could decrease LPS-induced nitric oxide (NO) production. Western blotting results showed that NCTS could down-regulate LPS-induced expression of inducible nitric oxide synthase (iNOS), p-IκBα, p-IKKβ and p-NF-κB p65 without affecting cyclooxygenase-2 (COX-2). In addition, NCTS inhibited LPS-induced p-NF-κB p65 nuclear translocation. In conclusion, these data demonstrated that NCTS showed anti-inflammatory effect by suppression of NF-κB and iNOS signaling pathways.

Abstract
Twelve hydrolyzable tannins were obtained from the twigs of Myricaria bracteata, including two new hellinoyl-type dimers, bracteatinins D1 (1) and D2 (2); a new hellinoyl-type trimer, bracteatinin T1 (3); two known monomers, nilotinin M4 (4) and 1,3-di-O-galloyl-4,6-O-(aS)-hexahydroxydiphenoyl-β-d-glucose (5); six known dimers, tamarixinin A (6), nilotinin D8 (7), hirtellins A (10), B (9), and E (8), and isohirtellin C (11); and a known trimer, hirtellin T3 (12). The structures of the tannins were elucidated by spectroscopic data analysis and comparisons to known tannins. All compounds were evaluated as free radical scavengers using 1,1-diphenyl-2-picrylhydrazyl and hydroxy radicals and compared to the activity of BHT and Trolox. Compound 6 showed a significant anti-inflammatory effect on croton oil-induced ear edema in mice (200 mg/kg, inhibition rate 69.8%) and on collagen-induced arthritis in DBA/1 mice (20 mg/kg, inhibition rate 46.0% at day 57).

Abstract
Methyl salicylate-2-O-β-d-lactoside (MSL) is a natural salicylate derivative from the traditional Chinese medicine of Gaultheria yunnanensis (Franch.) Rehder (G. yunnanensis). As a non-steroidal anti-inflammatory drug (NSAID), MSL exerts a significant anti-arthritis effect but hardly has any gastrointestinal toxicity. In this paper, the pharmacokinetics, distribution, excretion and identification of MSL and its metabolites are described following rat oral and intravenous administration. The biological samples were quantified by UPLC-MS/MS and the metabolites in urine and feces were identified by using Q-TOF-MS. These results will support future investigations leading to clinical development of this drug.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Methyl salicylate-2-O-β-d-lactoside (MSL) is one of the main active components isolated from Gaultheria yunnanensis, which is a traditional Chinese medicine used to treat arthritis and various aches and pains. Pharmacological researches showed that MSL had various effective activities in both in vivo and in vitro experiments. However, the pharmacokinetics features and oral bioavailability of MSL in primates were not studied up to now. AIM To study the pharmacokinetics of different doses of MSL in rhesus monkeys and investigate the absolute bioavailability of MSL after oral administration. MATERIALS AND METHODS Male and female rhesus monkeys were either orally administrated with MSL 200, 400 and 800 mg/kg or received an intravenous dose of 20mg/kg randomly. The levels of MSL and salicylic acid (SA) in plasma were simultaneous measured by a simple, sensitive and reproducible high performance liquid chromatography method. RESULTS Mean peak plasma concentration values for groups treated with 200, 400 and 800 mg/kg doses ranged from 48.79 to 171.83 μg/mL after single-dose oral administration of MSL, and mean area under the concentration-time curve values ranged from 195.16 to 1107.76 μg/mL h. Poor linearity of the kinetics of SA after oral administration of MSL was observed in the regression analysis of the Cmax-dose plot (r(2)=0.812), CL-dose plot (r(2)=0.225) and AUC(0-t)-dose plot (r(2)=0.938). Absolute bioavailability of MSL was assessed to be 118.89 ± 57.50, 213.54 ± 58.98 and 168.72 ± 76.58%, respectively. CONCLUSIONS Bioavailability of MSL after oral administration in rhesus monkeys was measured for the first time. Pharmacokinetics parameters did not appear to be dose proportional among the three oral doses of treatments, and MSL showed an apparent absolute bioavailability in excess of 100% in rhesus monkeys based on the present study. In addition, a rapid, sensitive and reliable HPLC method was established and demonstrated for the research of traditional Chinese medicine in this study.

Abstract
Methyl salicylate 2-O-β-D-lactoside (MSL) is a derivative of natural salicylate isolated from Gaultheria yunnanensis (Franch.) Rehder, which is widely used for treating rheumatoid arthritis (RA), swelling and pain. The aim of the present study was to investigate the effect of MSL on the progression of adjuvant-induced arthritis (AIA) in rat in vivo and explore the anti-inflammatory effects and mechanism of MSL in lipopolysaccharide (LPS)-treated murine macrophages RAW264.7 cells in vitro. Our results showed that MSL significantly inhibited the arthritis progression in AIA rats, decreasing the right hind paw swelling and ankle diameter, attenuating histopathological changes and suppressing the plasma levels of TNF-α and IL-1β in AIA rats. Besides, MSL had potent anti-inflammatory effects on the LPS-activated RAW264.7. MSL dose-dependently inhibited the activity of COX-1, and COX-2. Moreover, MSL prominently inhibited LPS-induced activation of MAPK in RAW264.7 cells by blocking phosphorylation of p38 and ERK. Our study suggests that MSL may be effective in the treatment of inflammatory diseases by inhibiting the pro-inflammatory cytokine production and regulating the MAPK signal pathway.
