2,3,4',5-Tetrahydroxystilbene-2-O-β-d-glucoside attenuates atherosclerotic progression by inhibiting inflammation via downregulation of TNF receptor-associated factor 6 expression.
    European review for medical and pharmacological sciences, 2023, Volume: 27, Issue:10

    Atherosclerosis (As) is an inflammatory disease, and 2,3,4',5-tetrahydroxystilbene-2-O-β-d-glucoside (TSG) has been shown to suppress inflammation. However, it is still unclear if TSG alleviates As by inhibiting inflammation.. Quantitative real-time polymerase chain reaction (qRT-PCR) was performed to assess the mRNA levels of tumor necrosis factor (TNF) receptor-associated factor 6 (TRAF6), TNF-α and interleukin-6 (IL-6) in lipoprotein E knockout (ApoE -/-) mice with As. Hematoxylin-eosin (H&E) staining was performed to examine the atherosclerotic plaques in the aortic sinus. QRT-PCR and western blotting were used to measure the expression levels of TRAF6, TNF-α, and IL-6 in human umbilical vein endothelial cells (HUVECs), and enzyme-linked immunosorbent assays (ELISAs) were performed to monitor the levels of TNF-α and IL-6 in serum and cell culture medium.. TSG inhibited subendothelial plaques formation in the aortic sinus and inhibited the levels of total cholesterol (TCHO), low-density lipoprotein (LDL), TRAF6, TNF-α and IL-6 in AS mice in a dose-dependent manner. Moreover, TSG attenuated the oxidatively modified LDL (ox-LDL)-induced increases in TRAF6, TNF-α and IL-6 expression, whereas TRAF6 overexpression reversed the TSG-induced decreases in TRAF6, TNF-α, and IL-6 expression in HUVECs.. TSG attenuates atherosclerotic progression by inhibiting inflammation via the downregulation of TRAF6 in ApoE-/- mice and HUVECs.

2,3,5,4'‑Tetrahydroxystilbene‑2‑O‑β‑D‑glucoside inhibits septic serum‑induced inflammatory injury via interfering with the ROS‑MAPK‑NF‑κB signaling pathway in pulmonary aortic endothelial cells.
    International journal of molecular medicine, 2018, Volume: 41, Issue:3

    Sepsis is characterized by injury to the microvasculature and the microvascular endothelial cells, leading to barrier dysfunction. However, the specific role of injury in septic endothelial barrier dysfunction remains to be elucidated. In the present study, it was hypothesized that endothelial cell inflammatory injury is likely required for barrier dysfunction under septic conditions in vitro. 2,3,5,4'‑Tetrahydroxystilbene‑2‑O‑β‑D‑glucoside (TSG), a compound extracted from Chinese herbs, is able to inhibit the inflammatory injury of septic‑serum in endothelial cells. In the present study, cell viability was assayed by CCK‑8 method; mRNA and protein expression was identified by RT‑qPCR, western blot or Elisa, respectively and the production of reactive oxygen species was observed by a fluorescence microscope. The present study indicated that septic serum significantly decreased the cell viability of pulmonary aortic endothelial cells (PAECs) following co‑cultivation for 6 h, which occurred in a time‑dependent manner. TSG notably increased the viability of PAECs in a time‑ and concentration‑dependent manner. Further investigations revealed that septic serum increased the secretion of interleukin (IL)‑1β, IL‑6 and C‑reactive protein in PAECs, whereas pretreatment with TSG significantly decreased the secretion of these inflammatory factors. These data indicated that septic serum increased inflammatory injury to the PAECs, and TSG decreased this injury via the reactive oxygen species‑mitogen‑activated protein kinase‑nuclear factor‑κB signaling pathway.

The Protective Effects of 2,3,5,4'-Tetrahydroxystilbene-2-
    International journal of molecular sciences, 2018, Dec-12, Volume: 19, Issue:12

    Asthma is an inflammatory disease caused by an imbalance of Th1 and Th2 cells. In general, asthma is characterized by a stronger Th2 response. Most conventional asthma treatment focuses on improving airway flow or suppression of airway inflammation. To reduce the side effects of currently used asthma medicines, we have conducted studies on natural products that have no side effects. 2,3,5,4'-tetrahydroxystilbene-2-O-β-d-glucoside (TSG), the main compound of

2,3,4',5-tetrahydroxystilbene-2-O-β-d-glucoside exerts anti-inflammatory effects on lipopolysaccharide-stimulated microglia by inhibiting NF-κB and activating AMPK/Nrf2 pathways.
    Food and chemical toxicology : an international journal published for the British Industrial Biological Research Association, 2016, Volume: 97

    2,3,4',5-Tetrahydroxystilbene-2-O-β-d-glucoside (THSG) affects neuroinflammation-related neurodegenerative diseases and inhibits neuroinflammatory mediators. However, the detailed impacts and underlying mechanisms of THSG on neuroinflammatory responses are still unclear. The aim of this study was to investigate the anti-neuroinflammatory mechanism of THSG via AMPK/Nrf2 signaling pathways. This study showed that THSG attenuated LPS-induced iNOS, COX-2, TNF-α, and IL-6 activation in microglia. Furthermore, it was observed that activation of IκBα and NF-κB was significantly increased upon LPS stimulation, and suppressed by THSG treatment in a dose-dependent manner. The expression of HO-1 and NQO1, as well as Nrf2 activation, was induced by THSG in microglia. The promoter activity of ARE and HO-1 also increased in a dose-dependent manner following THSG treatment. Nrf2/HO-1/NQO1 has anti-inflammatory properties; the knock-down of Nrf2/HO-1/NQO1 by specific siRNA prevented the THSG-mediated inhibition of iNOS and COX-2 promoter activity. Consistent with this concept, the phosphorylation of LKB1, CaMKII, and AMPK were elevated after THSG treatment. The blockade of AMPK by a pharmacological inhibitor prevented THSG-induced HO-1 and NQO1 expression. The anti-inflammatory properties of THSG were also reversed by treatment with an AMPK inhibitor. In conclusion, we demonstrated that THSG attenuates the LPS-induced neuroinflammatory response mediated by AMPK/Nrf2 signaling pathways.

Naturally Occurring Stilbenoid TSG Reverses Non-Alcoholic Fatty Liver Diseases via Gut-Liver Axis.
    PloS one, 2015, Volume: 10, Issue:10

    The gut-liver axis is largely involved in the development of non-alcoholic fatty liver disease (NAFLD). We investigated whether 2, 3, 5, 4'-tetrahydroxy-stilbene-2-O-β-D-glucoside (TSG) could reverse NAFLD induced by a high-fat diet (HFD) and whether it did so via the gut-liver axis. Results showed that TSG could reduce the accumulation of FFA and it did so by reducing the expression of L-FABP and FATP4. TSG regulated gut microbiota balanced and increased the protein expression of ZO-1 and occludin, which could improve the function of the intestinal mucosal barrier and reduce serum LPS content by about 25%. TSG reduced TL4 levels by 56% and NF-κB expression by 23% relative to the NAFLD model group. This suggests that prevention of NAFLD by TSG in HFD-fed rats is mediated by modulation of the gut microbiota and TLR4/NF-κB pathway, which may alleviate chronic low-grade inflammation by reducing the exogenous antigen load on the host.

Tetrahydroxystilbene glucoside attenuates neuroinflammation through the inhibition of microglia activation.
    Oxidative medicine and cellular longevity, 2013, Volume: 2013

    Neuroinflammation is closely implicated in the pathogenesis of neurological diseases. The hallmark of neuroinflammation is the microglia activation. Upon activation, microglia are capable of producing various proinflammatory factors and the accumulation of these factors contribute to the neuronal damage. Therefore, inhibition of microglia-mediated neuroinflammation might hold potential therapy for neurological disorders. 2,3,5,4'-Tetrahydroxystilbene-2-O-β-D-glucoside (TSG), an active component extracted from Polygonum multiflorum, is reported to be beneficial for human health with a great number of pharmacological properties including antioxidant, free radical-scavenging, anti-inflammation, antilipemia, and cardioprotective effects. Recently, TSG-mediated neuroprotective effects have been well demonstrated. However, the neuroprotective actions of TSG on microglia-induced neuroinflammation are not known. In the present study, microglia BV2 cell lines were applied to investigate the anti-neuroinflammatory effects of TSG. Results showed that TSG reduced LPS-induced microglia-derived release of proinflammatory factors such as TNFα, IL-1β, and NO. Moreover, TSG attenuated LPS-induced NADPH oxidase activation and subsequent reactive oxygen species (ROS) production. Further studies indicated that TSG inhibited LPS-induced NF-κB signaling pathway activation. Together, TSG exerted neuroprotection against microglia-mediated neuroinflammation, suggesting that TSG might present a promising benefit for neurological disorders treatment.

Proteomic analysis for anti-atherosclerotic effect of tetrahydroxystilbene glucoside in rats.
    Biomedicine & pharmacotherapy = Biomedecine & pharmacotherapie, 2013, Volume: 67, Issue:2

    2,3,5,4'-tetrahydroxystilbene-2-O-β-D-glucoside (TSG) extracted from Polygonum multiflorum (a traditional Chinese medicinal herb) has been proved to exhibit significant anti-atherosclerotic activity. In this study, we firstly used proteomic analyses to investigate the molecular events occurring in the atherosclerotic rats after TSG treatment. Aortic samples were collected from the atherosclerotic rat group and the TSG-treated group, and its proteome was analyzed by two-dimensional gel electrophoresis (2-DE). Proteins showing significant changes in expression were identified and analyzed by matrix-assisted desorption/ionization time of flight mass spectrometry (MALDI-TOF-MS). As a result, 21 protein spots were found with significant differential expression after the treatment with TSG. A total of 18 spots were identified by database searching, and 17 spots matched with known proteins. Among these proteins (11 proteins up-regulated and six proteins down-regulated), five proteins were mainly involved in inflammation, cholesterol transport, cell apoptosis and adhesion. TSG treatment enhanced the expression of HSP 70, lipocortin 1 and Apo A-I, and inhibited the expression of calreticulin, vimentin. Furthermore, we randomly selected four proteins and confirmed the results of proteomic analysis by RT-PCR and western blotting. In conclusion, TSG treatment suppresses atherosclerosis by altering the expression of different proteins. Calreticulin, vimentin, HSP 70, lipocortin 1, and Apo A-I, are key proteins that may be novel molecular targets responsible for atherogenesis suppression induced by TSG treatment.

2,3,4',5-Tetrahydroxystilbene-2-O-beta-D-glucoside suppresses matrix metalloproteinase expression and inflammation in atherosclerotic rats.
    Clinical and experimental pharmacology & physiology, 2008, Volume: 35, Issue:3

    1. In coronary artery disease, the typical atheromatous plaque consists of a lipid core containing various inflammatory cells and a fibrous cap composed mostly of extracellular matrix. Both matrix metalloproteinases (MMPs) and inflammation are involved in the initiation of atherosclerotic plaques and plaque instability. 2. 2,3,4 cent,5-Tetrahydroxystilbene-2-O-beta-D-glucoside (TSG) reduces the blood lipid content and prevents the atherosclerotic process, but the mechanism of action of TSG is unclear. The purpose of the present study was to test whether TSG can suppress MMP activation and inflammation in atherosclerotic rats. 3. Sixty male Sprague-Dawley rats were randomly divided into six groups. Atherosclerosis was induced by feeding rats a hyperlipidaemic diet; TSG (120, 60 or 30 mg/kg per day) was administered by oral gavage. After 12 weeks of treatment, rats were killed (ethyl carbamate 1200 mg/kg) and serum lipids, C-reactive protein (CRP), interleukin (IL)-6 and tumour necrosis factor (TNF)-alpha were measured. Haematoxylin-eosin (H&E) staining was used to examine histopathological changes in the aorta. The mRNA and protein expression of MMPs were assayed by reverse transcription-polymerase chain reaction, immunohistochemistry and western blotting. Simvastatin (2 mg/kg per day) was administered as a positive control, whereas the vehicle (0.9% NaCl) group served as the untreated control. 4. In the present study, TSG significantly and dose-dependently attenuated the hyperlipidaemic diet-induced alterations in serum lipid profile and increases in CRP, IL-6 and TNF-a levels. In addition, TSG normalized the structure of the aortic wall and suppressed the expression of MMP-2 and MMP-9 at both the mRNA and protein level in the rat aortic wall. 5. In summary, TSG suppresses the expression of MMP-2 and MMP-9 and inhibits inflammation in the diet-induced atherosclerotic rats.
