Abstract
Background & objectives To examine β-D-mannuronic acid (M2000) effects on L-selectin shedding and leucocyte function-associated antigen-1 (LFA-1) expression as mechanisms of action of this drug in patients with ankylosing spondylitis (AS). Methods To investigate the molecular consequences of β-D-mannuronic acid on L-selectin shedding, flow cytometry method was used. Furthermore, the effect of it on LFA-1 gene expression was analyzed by using quantitative real time (qRT)-PCR technique. Results The LFA-1 expression in patients with AS was higher than controls (P=0.046). The LFA-1 expression after 12 wk therapy with β-D-mannuronic acid was meaningfully decreased (P=0.01). After 12 wk treatment with β-D-mannuronic acid, the frequency of CD62L-expressing CD4+ T cells in patients with AS, was not considerably altered, compared to the patients before therapy (P=0.5). Furthermore, after 12 wk therapy with β-D-mannuronic acid, L-selectin expression levels on CD4+ T-cells in patients with AS, were not remarkably changed, compared to the expression levels of these in patients before treatment (P=0.2). Interpretation & conclusions The results of this study for the first time showed that β-D-mannuronic acid can affect events of adhesion cascade in patients with AS. Moreover, β-D-mannuronic acid presented as an acceptable benefit to AS patients and could aid in the process of disease management.

Abstract
Aim: The importance of chronic inflammation during the progression of prostate cancer (PCa) is well-known. M2000 (β-d-mannuronic acid) is a novel anti-inflammatory drug. According to its potential capacity for the inhibition of molecules involved in creating conditions of inflammation, it is reasonable to assess the anti-inflammatory role of M2000 in PCa cells.Methods: MTT assay was performed to determine the cytotoxicity of M2000 in PC3 cells. Correspondingly, these cells were cultured and then treated with low (25 µg/ml) and high (50 µg/ml) doses of M2000 as optimal doses. Thereafter, real-time RT-PCR, flow cytometry analysis, and zymography were performed to evaluate the expressions of MYD-88, NF-kB, IL-8, COX-2, MMP-2, and MMP-9 molecules. Results: Of note, the M2000 at the concentration of ≤200 μg/ml had no cytotoxicity effect on the cells. MYD-88 gene expression was significantly down-regulated at both low and high doses in the M2000-treated cells compared to the control (p = .017 and p = .001, respectively). The expression of the NF-kB was also reduced at both the gene and protein levels (all p values were <.001). The expression of IL-8 and COX-2 genes was also down-regulated in the high dose of M2000 (p<.001, p = .001, respectively). The decreased expression of the MMP-9 gene was observed at both doses (both p values were <.001).Conclusion: Inhibitory effects of M2000 on the activity of MMPs in the LPS/M2000-treated cells were evident, but not in the M2000-treated cells. M2000 as a new anti-inflammatory drug appears to constitute a potential agent for down-regulation of inflammatory molecules in the PCa cells.

Abstract
A water-soluble polysaccharide (LCP-05) was isolated from the flowers of Leucosceptrum canum Smith. LCP-05 was an acidic polysaccharide with a molecular weight of approximately 8.9 kDa. Monosaccharide composition analysis indicated that LCP-05 was composed of Man, Rha, GlcA, GalA, Glc, Gal and Ara in a molar ratio of 0.83:1.68:0.33:2.15:1.00:1.45:1.22. The framework of LCP-05 was speculated to be a branched rhamnogalacturonan with the backbone consisting of α-1,2,4-linked Rhap and α-1,4-linked GalAp, and bearing branches at the O-4 position of the Rha residues. The side chains are terminated primarily with the Araf and Glcp residues. LCP-05 was found to be able to significantly induce the production of NO, IL-6, and TNF-α in RAW 264.7 cells, and to induce RAW 264.7 cell's suppressive effect on both cell growth and cell migration of 4 T1 mammary breast cancer cells.

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.

The drug has shown a punchy effect on many molecules which participate either in physiologic or in pathogenic activities in animal models and human. This new drug not only revealed the anti-inflammatory and immunosuppressive properties but also based on the results of various investigations, β-D-Mannuronic Acid showed the antidiabetic, cardioprotective and anti-tumoral effects. CONCLUSION β-D-Mannuronic Acid (M2000) as a novel immunosuppressive drug with NSAID properties along with antidiabetic, cardioprotective and anti-tumoral efficacy showed great tolerability and safety profile. In addition, it has no or mild adverse events compared with many other medicines, therefore this medicament could be considered as a landmark in pharmacology and represent turn point in the treatment of different diseases based on the experimental and in vitro studies explained and clinical and related studies proved.
