Curr Drug Discov Technol 2021; 18:65-74. [PMID: 31657689 DOI: 10.2174/1570163816666191023103118] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2019] [Revised: 07/15/2019] [Accepted: 08/28/2019] [Indexed: 06/10/2023]
Abstract
BACKGROUND Based on the encouraging results of phase III clinical trial of β-Dmannuronic acid (M2000) (as a new anti-inflammatory drug) in patients with RA, in this study, we aimed to evaluate the effects of this drug on the expression of chemokines and their receptors in PBMCs of RA patients. METHODS PBMCs of RA patients and healthy controls were separated and the patients' cells were treated with low, moderate and high doses (5, 25 and 50 μg/mL) of M2000 and optimum dose (1 μg/mL) of diclofenac, as a control in RPMI-1640 medium. Real-time PCR was used for evaluating the mRNA expression of CXCR3, CXCR4, CCR2, CCR5 and CCL2/MCP-1. Cell surface expression of CCR2 was investigated using flow cytometry. RESULTS CCR5 mRNA expression reduced significantly, after treatment of the patients' cells with all three doses of M2000 and optimum dose of diclofenac. CXCR3 mRNA expression was downregulated significantly followed by the treatment of these cells with moderate and high doses of M2000 and optimum dose of diclofenac. CXCR4 mRNA expression declined significantly after the treatment of these cells with moderate and high doses of M2000. CCL2 mRNA expression significantly reduced only followed by the treatment of these cells with a high dose of M2000, whereas, mRNA and cell surface expressions of CCR2 diminished significantly followed by the treatment of these cells with a high dose of M2000 and optimum dose of diclofenac. CONCLUSION According to our results, M2000 through the down-regulation of chemokines and their receptors may restrict the infiltration of immune cells into the synovium.

[PMID: 32200257 DOI: 10.1016/j.biopha.2020.110094] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2020] [Revised: 03/09/2020] [Accepted: 03/09/2020] [Indexed: 01/01/2023] Open
Abstract
UVA radiation from the sun is the main external stimulus in the pathogenesis of skin photo-aging. This process is associated with cellular oxidative stress. Here we aim at showing the protective effect of d-Tetramannuronic Acid Tetrasodium Salt (M4), a natural product, against UVA (30J/cm2) irradiation-induced oxidative stress and photo-aging in HaCaT cells, and to reveal the molecular mechanism underlying the protective efficacy. M4 pretreatment significantly increased HaCaT cell viability and MMP, suppressing UVA-induced ROS generation. Moreover, M4 treatment prevented the UVA-induced photo-aging of HaCaT cells (the reduction of cell viability, mitochondria dysfunction, and SIRT1/pGC-1α deregulation). Notably, the anti-photo-aging potential of M4 was directly associated with the increased expression of MMP and SIRT1, which was followed by the up-regulation of pGC-1α, D-LOOP, and Mt-TFA, and the transcriptional activation of NRF1/NRF2. Therefore, M4 is useful for the protection of skin cells from UVA-induced photo-aging.

Abstract
This research aimed to evaluate the anti-diabetic effects of β-d-mannuronic acid (M2000) on blood glucose, insulin production, and inflammatory markers in streptozotocin-induced diabetic rats. Our data showed that the final fasting serum glucose level was significantly lower in the M2000-treated group compared to the diabetic control group (p < .05). In addition, the final fasting serum insulin level significantly increased in the M2000-treated group compared to the diabetic control group (p < .05). Our finding revealed that the serum level of hs-CRP and IL-6 decreased significantly in the M2000-treated group compared to the diabetic control group (p < .05). This study showed that M2000, as a new NSAID, was able to decrease serum glucose levels and increase serum insulin levels and this drug could significantly decrease the inflammatory markers in the M2000-treated group. Collectively, treatment with M2000 might be recommended reducing the severity of diabetes-induced inflammatory symptoms.

Abstract
OBJECTIVE This research aimed to study the anti-aging and anti-inflammatory effects of low and high doses of the β-D-mannuronic (M2000) on gene expression of enzymes involved in oxidative stress (including SOD2, GST, GPX1, CAT, iNOS, and MPO) in peripheral blood mononuclear cells (PBMCs) of healthy donors under in vitro conditions. METHODS The PBMCs were separated and the RNAs were then extracted and the cDNAs synthesized, and expression levels of the mentioned genes were detected by qRT-PCR. RESULTS Our results indicated that the high dose of this drug could significantly reduce the expression level of the SOD2 gene compared to the lipopolysaccharide (LPS) group (p < 0.0001). Moreover, it was found that the high dose of this drug could significantly decrease the expression level of the GST gene compared to the LPS group (p < 0.0001). However, no significant reductions were observed in expression levels of the CAT and GPX1 genes compared to the LPS group. Furthermore, our data revealed that the level of iNOS and MPO gene expression was significantly reduced, in both doses of M2000, respectively, compared to the LPS group (p < 0.0001). CONCLUSION This research showed that M2000 as a novel NSAID with immunosuppressive properties could modify oxidative stress through lowering expression levels of the SOD2, GST, iNOS, and MPO genes compared to the healthy expression levels, with a probable reduction of the risk of developing inflammatory diseases related to age and aging.

Abstract
BACKGROUND/OBJECTIVES Anti-inflammatory agents play a crucial role in controlling inflammatory diseases such as Inflammatory Bowel Disease (IBD) but their use is restricted due to their vast side effects. M2000 (β-D-mannuronic acid) is a new immunomodulatory drug. According to the capacity of M2000 in suppressing some molecules involved in Toll Like Receptors (TLRs) signaling and reducing oxidative stress we hypothesize that, this molecule may have a potential role in decreasing inflammatory responses in IBD. The aim of this study was to evaluate the cytotoxicity of M2000 and its effect on the gene expression of TLR2 and TLR4. METHODS HEK293 cell line was grown and divided into 96-well cell plate and MTT assay was performed. HT29 cells were cultured and treated with low and high doses of M2000. Total RNA was extracted and cDNA synthesized and quantitative real-time PCR was done to quantify the TLR2 and TLR4 mRNA expression. RESULTS We found that M2000 at the concentration of ≤ 1000µg/ml had no obvious cytotoxicity effect on the HEK293 cells. Also, low and high doses of M2000 could significantly down-regulate both TLR2 and TLR4 mRNA expression. Moreover, a significant reduction in gene expression of TLR2 and TLR4 in an inflammatory condition resulted in high doses of M2000 in the presence of LPS. CONCLUSION Our study which was conducted in colonic epithelial cell model, shows that M2000 can be considered as a new anti-inflammatory agent in IBD. However, more comprehensive experimental and clinical studies are required to recognize the molecular mechanism of M2000 and also its safety and efficacy.

Abstract
CONTEXT The investigations have shown that patients with diabetes have the elevated levels of glucose and oxLDL. These two play an important role in increased expression levels of oxLDL scavenger receptors on the surface of macrophages and endothelial cells that leads to deposition of oxLDL and macrophages in vascular walls. OBJECTIVE The present study intends to show the effects of β-d-mannuronic acid (M2000) on the expression profile of ox-LDL scavenger receptors (including SR-A, LOX-1, CD36, and CD68) in an experimental model of diabetes. MATERIALS AND METHODS Eighteen Sprague-Dawley rats were randomly divided into three 6-member groups of the healthy control, diabetic control, and treated rats by M2000. Diabetes was induced in rats by intraperitoneal (IP) administration of 60 mg/kg streptozotocin. The treated rats were given daily intraperitoneal injections of M2000 with a dose of 25 mg/kg for 28 days and at the end of the 28th day, their aortas were removed. The qRT-PCR technique was then used to evaluate the expression levels of the proposed gene. RESULTS The gene expression levels of the SR-A, LOX-1, CD36, and CD68 significantly declined in the diabetic group that received M2000 compared with untreated diabetic rats. CONCLUSIONS The M2000, as a novel NSAID is able to modify by lowering the gene expression levels of SR-A, LOX-1, CD36, and CD68 in treated rats compared to the untreated diabetic group, which may play an important role in preventing the complications that could lead to a cardioprotective efficacy.

Abstract
BACKGROUND To explore the effects of β-d-mannuronic acid (M2000) on levels of Th17, regulatory T (Treg) cells and their related cytokines in patients with ankylosing spondylitis (AS). METHODS 30 AS patients and 15 age and sex-matched healthy individuals were enrolled in this study. The frequencies of Th17 and Treg cells and serum levels of related cytokines were measured by flow cytometry analysis and ELISA respectively, before (baseline) and 3 months after M2000 therapy. RESULTS Significantly higher baseline Th17 cells and serum IL-17, TNF-α and IL-6 were observed in AS patients than in normal controls, whereas baseline levels of Treg cells and serum IL-10 were not significantly different between AS patients and healthy controls. After M2000 therapy, frequencies of Th17 and serum levels of IL-17 and IL-6 significantly decreased in AS patients. The frequencies of Treg cells and serum level of IL-10 were not significantly changed, in comparison to before therapy. Moreover, the correlation analysis showed that frequencies of Th17 and levels of IL-17, TNF-α and IL-6 were positively correlated with Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) and Bath Ankylosing Spondylitis Functional Index (BASFI) scores, whereas Treg cells were revealed to be negatively correlated with BASDAI and BASFI scores. CONCLUSIONS It can be concluded that the oral administration of M2000 as a novel NSAID with the immunosuppressive property that down-regulates Th17 and Th17-related cytokines and facilitates the correction of the Th17/Treg imbalance can be effective in the process of AS treatment.
