Nat Prod Res 2023:1-7. [PMID: 37820042 DOI: 10.1080/14786419.2023.2269591] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2023] [Accepted: 10/01/2023] [Indexed: 10/13/2023]
Abstract
A series of C21 steroidal glycosides were isolated from the root bark of Periploca sepium, including a new compound, perisepiumoside A1 (1), and six known compounds (2-7). Their structures were elucidated by analysis of HR-ESI-MS, and 1D and 2D NMR spectroscopic data. All these compounds were tested for their NO production inhibitory activity in LPS-stimulated RAW 264.7 cells. Results showed that these C21 steroidal glycosides could remarkably inhibit NO production, particularly 1 and 2 with IC50 values of 30.81 ± 0.18 μM and 44.39 ± 0.21 μM, respectively. In addition, the cytotoxicity of these compounds was measured on A549, MCF-7, and HeLa cancer cell lines. Among them, compounds 1 and 7 displayed cytotoxicity against the A549 cell line with IC50 values of 28.41 ± 0.12 μM and 39.06 ± 0.05 μM, respectively.

Int J Rheum Dis 2023; 26:613-624. [PMID: 36680325 DOI: 10.1111/1756-185x.14560] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2022] [Revised: 12/14/2022] [Accepted: 12/24/2022] [Indexed: 01/22/2023]
Abstract
Rheumatoid arthritis (RA) is a persistent systemic autoimmune disease, having all the hallmarks of joint swelling, joint tenderness, and progressive joint destruction, with synovitis and pannus formation as the basic pathological changes. T-lymphocyte infiltration is the key to its pathogenesis. During the growth of RA, the share of regulatory T (Treg) cells decreases, while the percentage of T helper type 17 (Th17) cells increases, giving rise to an imbalance of Th17/Treg cells. Modern medicine has made great advances in the treatment of RA and the selection of available drugs, but there are also the disadvantages of gastrointestinal reaction, high price, and low patient compliance. Therapy of RA remains a problem. Traditional Chinese medicine (TCM) has RA therapy developments, both in experimental research and clinical research, and its advantages of lasting effects and less detrimental reactions and fewer adverse effects are accepted by most patients. Numerous clinical and experimental studies have been performed in TCM on regulating Th17/Treg balance. However, the detailed mechanism of TCM intervention in Th17/Treg equilibrium in preventing and treating RA has not been discovered. In this article, the theory of regulating Th17/Treg cell equilibrium in RA is described from the perspectives of single Chinese medicine, active components of Chinese medicine, Chinese medicine compounds, and other therapies of TCM. It was found that TCM can regulate Th17/Treg cell balance and inhibit immunoreaction by intervening in cytokines, transcription factors, and signal pathways. It enables us to comprehensively and deeply understand the mechanism of TCM intervening in Th17/Treg balance in RA; provides direction for clinical therapy of RA; and offers new thoughts for understanding the pathogenesis of RA.

Abstract
A sensitive and specific ultra-performance liquid chromatographic-tandem mass spectrometric method was developed and validated to simultaneously determine periplocin, periplocymarin (PM), periplogenin (PG), periplocoside M (PSM) and periplocoside N (PSN) in rat plasma. Acetonitrile was employed to precipitate plasma with appropriate sensitivity and acceptable matrix effects. Chromatographic separation was performed using a Waters HSS T3 column with a gradient elution using water and acetonitrile both containing 0.1% formic acid and 0.1 mm ammonium formate within 8 min. Detection was performed in positive ionization mode using multiple reaction monitoring. The method was fully validated in terms of selectivity, linearity, accuracy, precision, recovery, matrix effects and stability. Using this method, the concentrations of periplocin, PM, PG, PSM and PSN were established after oral administration of Cortex Periplocae extract to rats, and the pharmacokinetic characteristics of periplocin, PM, PG, PSM and PSN were assessed. Generally, PM, PG, PSM and PSN were eliminated slowly and their half-lives were all >8 h. In addition, the systemic exposure of PSM showed significant differences between genders with more than 10 times higher area under the concentration-time curve in female rats than in male rats. The findings of this study provide useful information for further research on Cortex Periplocae.

Biomaterials 2021; 278:121160. [PMID: 34653934 DOI: 10.1016/j.biomaterials.2021.121160] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2021] [Revised: 09/22/2021] [Accepted: 09/27/2021] [Indexed: 12/18/2022]
Abstract
Interleukin-4 (IL4), a Th2-type cytokine that can drive M2 macrophage polarization, is expected to be used as an anti-inflammatory therapy agent as M2 polarization of macrophages can ameliorate chronic inflammation. However, several problems, such as the low effectiveness and side effects, have hampered the clinical application. To safely and effectively use IL4, an efficient delivery of IL4 to target cells, macrophages, is necessary. Small extracellular vesicles (sEVs) are promising candidates as macrophage delivery carriers because they are efficiently recognized by macrophages. In addition, considering the property of IL4 signaling, for which the internalization of IL4 receptor into the cellular compartment is important, and sEV uptake mechanism by macrophages, sEVs are expected to amplify IL4 signaling. In this study, we developed IL4-carrying sEVs (IL4-sEVs) by genetically engineering sEV-producing cells. We investigated the bioactivity of IL4-sEVs using RAW264.7 macrophages and their potential for therapeutic application to the treatment of an inflammatory disease using collagen-induced arthritis model mice. IL4-sEVs exhibited stronger anti-inflammatory effects on M1-polarized macrophages through M2 polarization of macrophages than those of soluble IL4 proteins. Moreover, IL4-sEVs exhibited more effective therapeutic effects on rheumatoid arthritis than those of IL4. These results indicate that IL4-carrying sEVs are promising anti-inflammatory therapeutics.

Abstract
Regulatory T cells (Tregs) represent a distinct subpopulation of CD4+ T lymphocytes that promote immune tolerance and maintain immune system homeostasis. The dysfunction of Tregs is tightly associated with rheumatoid arthritis (RA). Although the complex pathogenic processes of RA remain unclear, studies on Tregs in RA have achieved substantial progress not only in fundamental research but also in clinical application. This review discusses the current knowledge of the characterizations, functions, and molecular mechanisms of Tregs in the pathogenesis of RA, and potential therapies for these disorders are also involved.

Abstract
BACKGROUND The present study aimed to determine the functional role of miR-206 in T helper 17 (Th17)/regulatory T (Treg) cell differentiation during the development of osteoarthritis (OA). METHODS Patients with OA and healthy controls were recruited for investigating the association between miR-206 and Th17/Treg ratio. Transfection experiments were conducted in CD4+ T cells to verify the mechanism of miR-206 on the balance of Treg/Th17. OA model was constructed to detect the clinical score, histopathological changes and Treg/Th17 ratio. OA model was induced in rats to verify the effect of miR-206 inhibition on Th17/Treg immunoregulation. RESULTS High expression of miR-206 was positively correlated with peripheral Th17/Treg imbalance in patients with OA. The interactions between miR-206 and the 3' untranslated regions (3'-UTR) of suppressor of cytokine signaling-3 (SOCS3) and fork head transcriptional factor 3 (Foxp3) were confirmed by luciferase reporter assays. MiR-206 disturbed the Th17/Treg balance by targeting SOCS3 and Foxp3. In vivo assay demonstrated that antagomiR directed against miR-206 restored Th17/Treg balance during the development of OA. CONCLUSION MiR-206 contributed to the progression of OA by modulating Th17/Treg imbalance, suggesting that miR-206 inhibition might be a promising therapeutic strategy for the treatment of OA.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Periploca sepium Bunge (P. sepium) is used in traditional Chinese medicine (TCM) for the treatment of autoimmune diseases, particularly rheumatoid arthritis. Periploca sepium periplosides (PePs), isolated from the root bark of P. sepium, characterized as the cardiac glycosides-free pregnane glycosides fraction, is expected to possess therapeutic potential on inflammatory arthritis. AIM OF THE STUDY The current study is designed to evaluate the anti-nociceptive, anti-inflammatory and anti-arthritic activities effects of the PePs. MATERIALS AND METHODS The anti-nociceptive activity of PePs was examined in the writhing test and hot-plate test in mice. The anti-inflammatory activity of PePs was determined by the 2, 4-dinitro-1-fluorobenzene (DNFB)-induced ear edema model and the carrageenan induced paw edema model in mice. The anti-arthritic activity of PePs was investigated by evaluating the joint inflammation and arthritis pathology in rat adjuvant induced arthritis (AIA) and murine collagen induced arthritis (CIA). Phytohaemagglutinin M (PHA-M) -elicited human peripheral blood mononuclear cells (PBMCs) were further applied to assess the suppressive activity of PePs on IFN-γ and IL-17 production. RESULTS PePs treatment markedly decreased the acetic acid-induced visceral nociceptive response and increased the hot-plate pain threshold. Further, oral administration of PePs exhibited anti-inflammatory activity by decreasing DNFB-induced ear edema in mice and carrageenan-induced paw edema in rats. Moreover, oral treatment of PePs ameliorated joint swelling and attenuated bone erosion in rodent arthritis, and the therapeutic benefits were partially attributed to the suppression of proinflammatory cytokines such IFN-γ and IL-17. Moreover, PePs suppressed the proliferation as well as IFN-γ and IL-17 secretion in PHA-M-elicited human PBMCs in a concentration dependent manner. CONCLUSIONS Taken together, our results justified the traditional use of Periploca sepium Bunge for the treatment of diseases associated with inflammation and pain.

Abstract
Rheumatoid arthritis (RA) is an autoimmune disease characterized by chronic inflammation and T cell hyper-activation. Emerging evidence has shown that the stimulation of immunoglobulin D (IgD) induces T cell activation and may contribute to disease pathogenesis. In this study, the sIgD concentrations were positively associated with disease activity score in 28 joints (DAS28) and anti-cyclic citrullinated peptide (anti-CCP) in RA. We demonstrated that IgD-Fc-Ig (composed of human IgD Fc domain and IgG1 Fc domain, obtained through prokaryotic protein expression and chromatography purification) effectively inhibited the activation and proliferation of T cells in healthy controls and PBMCs in RA patients stimulated by IgD, recovered the Th17/Treg cell subset balance, and downregulated p-Lck and p-ZAP70 expression. Moreover, in vivo, IgD-Fc-Ig decreased the swollen joint counts and arthritis indices in mice with collagen-induced arthritis (CIA), and ameliorated histopathological changes in joint and spleen tissue. It also downregulated thymocyte proliferation and reduced the percentage of helper T cells (Th) and CD154+ T cells, reversed the imbalance of Th1/Th2 and Th17/Treg cell subsets, reduced cytokine and chemokine levels, and inhibited p-Lck and p-ZAP70 expression. Our data suggest that IgD-Fc-Ig fusion protein regulates T cell activity in RA. These findings have potential implications for IgD-targeted strategies to treat IgD-associated RA.

Cinnamtannin D1 attenuates autoimmune arthritis by regulating the balance of Th17 and treg cells through inhibition of aryl hydrocarbon receptor expression. Pharmacol Res 2019; 151:104513. [PMID: 31706010 DOI: 10.1016/j.phrs.2019.104513] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/27/2019] [Revised: 09/20/2019] [Accepted: 10/23/2019] [Indexed: 12/19/2022]
Abstract
The suppression of the abnormal systemic immune response constitutes a primary strategy for treatment of rheumatoid arthritis (RA); toward this end, the identification of natural compounds with immunosuppressive activity represents a promising strategy for RA drug discovery. Cinnamtannin D1 (CTD-1), a polyphenolic compound isolated from Cinnamomum tamala, was previously reported to possess good immunosuppressive activity. However, the beneficial effect of CTD-1 on RA is currently unknown. The aim of this study was to evaluate the anti-arthritic effect of CTD-1 in collagen-induced arthritis (CIA) mice and clarify the underlying mechanisms. CTD-1 treatment significantly alleviated the severity of CIA mice, affording reduced clinical scores and paw swelling, along with reduced inflammatory cell infiltration and cartilage damage in the joints; in addition, the serum levels of IL-17, IL-6, and IL-1β were decreased whereas those of TGF-β and IL-10 were increased. CTD-1-treated mice exhibited lower frequency of Th17 cells and higher frequency of Treg cells compared to those in untreated mice, indicating that the balance of Th17/Treg cells may serve as the target for CTD-1. Consistent with this, in ex vivo assays, CTD-1 inhibited Th17 cell differentiation through the downregulation of phospho-STAT3/RORγt, whereas it promoted Treg differentiation by upregulating phospho-STAT5/Foxp3 in response to the stimulation of collagen type II. Moreover, in an in vitro naïve CD4+ T cell differentiation assay, CTD-1 directly inhibited Th17 cell differentiation and promoted Treg differentiation, suggesting that CTD-1 regulated the balance of Th17 and Treg cells to inhibit excessive immune response. Furthermore, the regulation effect of CTD-1 on Th17 and Treg cells was dependent on Ahr expression, as this effect was abolished when Ahr was knocked down and was impaired when Ahr was overexpressed. Together, our results indicated that CTD-1 treatment benefits CIA mice by regulating Th17 and Treg differentiation through the inhibition of AHR expression, and suggested a potential application of CTD-1 toward RA treatment.

Abstract
Rheumatoid arthritis (RA) is a systemic disease characterized by autoimmunity, joint inflammation, and cartilage destruction, which affects 0.5-1% of the population. Many compounds from herbal medicines show the potentials to treat RA. On this basis, the compounds with good pharmacokinetic behaviors and drug-likeness properties will be further studied and developed. Therefore, the herbal compounds with anti-RA activities were reviewed in this paper, and the cheminformatics tools were used to predict their drug-likeness properties and pharmacokinetic parameters. A total of 90 herbal compounds were analyzed, which were reported to be effective on RA models through anti-inflammation, chondroprotection, immunoregulation, antiangiogenesis, and antioxidation. Most of the herbal compounds have good drug-likeness properties. Most of the compounds can be an alternative and valuable source for anti-RA drug discovery.

Abstract
Rheumatoid arthritis (RA) is an autoimmune disease which is lack of effective therapies. Abnormal activation, proliferation, and differentiation of T lymphocytes are closely related to RA. Mesenchymal stem cells (MSCs) can be used for RA treatment due to their immunoregulatory effects. However, the specific molecular mechanisms have not been fully elucidated and the therapeutic effect has been inconsistent. This study investigated the immunomodulatory effect of human umbilical cord MSCs (hUCMSCs) on T lymphocytes in collagen-induced arthritis (CIA) rats and RA patients to clarify the possible mechanism of hUCMSCs in RA treatment. The effects of hUCMSCs on arthritis index, radiological and synovial pathological changes, T lymphocyte proliferation and apoptosis, RORγt and Foxp3 expression, Th17 and Treg cell ratios, and IL-17 and TGF-β levels were assessed in CIA rats. Further, we verified the effect of hUCMSCs in RA patients, and compared the effect of hUCMSCs with that of hUCMSC derived extracellular vesicles (EVs). The results showed that hUCMSCs inhibited the proliferation and promoted apoptosis in T lymphocytes, downregulated RORγt mRNA and protein expression, decreased Th17 cell ratio, upregulated Foxp3 mRNA and protein expression, and increased Treg cell ratio in the spleen. Furthermore, they downregulated RORγt and Foxp3 expression in the joints, and inhibited IL-17 and promoted TGF-β expression in the serum, thereby improving arthritis, delaying radiological progression, and inhibiting synovial hyperplasia in CIA rats. In vitro the effects of hUCMSCs and EVs were consistent with those in vivo. Therefore, hUCMSCs may be expected to serve as a new therapy for RA.

Abstract
Klebsiella pneumoniae causes severe infections including pneumonia and sepsis and treatments are complicated by increased levels of antibiotic resistance. We have identified a flavonoid kaempferol-3-O-glucorhamnoside derived from the plant Thesium chinense Turcz that possessed potent anti-inflammatory effects in K. pneumoniae infected mice. Administration of kaempferol-3-O-glucorhamnoside before bacterial challenge effectively suppressed expression of the major inflammatory cytokines TNF-α, IL-6, IL-1β and PGE2 and ameliorated lung edema. In addition, administration of this compound to cultured RAW macrophages or Balb/c mice resulted in the suppression of NFκB and MAP kinase phosphorylation indicating an inhibitory effect on inflammation in vitro and in vivo. Kaempferol-3-O-glucorhamnoside also decreased ROS levels and overall oxidative stress in lungs and in cultured cells generated by K. pneumoniae exposure. Taken together, kaempferol-3-O-glucorhamnoside is a potent anti-inflammatory in vitro and in vivo and is a promising therapeutic agent for treating K. pneumoniae infections in the clinic.

Abstract
The Yi Shen Juan Bi Pill (YSJB), a traditional Chinese compound herbal drug, has been used as an anti-rheumatic drug in clinical practice. Cartilage and bone destruction of inflamed joints is the hallmark of rheumatoid arthritis (RA). Our previous study suggested that YSJB had a protective effect on joint damage in collagen-induced (CIA) rats. However, the role and the mechanism of YSJB in inflammation-induced bone loss are unavailable. The current study aimed to further evaluate the effect of YSJB on the joint destruction and the systemic bone loss, and to clarify the potential mechanism. CIA model was generated by using collagen II and incomplete Freund's adjuvant in Sprague-Dawley rats. After 4 weeks treatment, arthritic index, tissue pathology, micro-computed tomography scanning (μ-CT), and bone mineral density (BMD) analysis were performed. YSJB decreased arthritic scores and bone destruction; improved the BMD of lumbar vertebrae and bone volume fraction of inflamed joints. Moreover, YSJB significantly decreased the production of serum bone resorption markers, including Tartrate-Resistant Acid Phosphatase (TRACP), N-terminal telopeptide of type I collagen and C-terminal telopeptide of type I collagen. Meanwhile, it increased the level of serum bone formation marker type I collagen N-terminal propeptide. These results revealed that YSJB ameliorated bone destruction and reduced bone loss induced by arthritis. We have previously showed that Tregs inhibited osteoclast differentiation and bone resorption in vitro. Furthermore, others suggested that abnormality of Th1, Th17 may contribute to bone destruction. Here, we showed YSJB significantly up-regulated the percentage of Tregs, while also down-regulated the percentage of Th1 and Th17 cells. Our findings provide the evidence that YSJB ameliorates the severity of disease and joint degradation, and reduces systemic bone loss induced by arthritis. We propose YSJB modulates the balance of T cell phenotype, which affects the activation and differentiation of osteoclasts.
