Abstract
The ocean is the common home of a large number of marine organisms, including plants, animals, and microorganisms. Researchers can extract thousands of important bioactive components from the oceans and use them extensively to treat and prevent diseases. In contrast, marine polysaccharide macromolecules such as alginate, carrageenan, Laminarin, fucoidan, chitosan, and hyaluronic acid have excellent physicochemical properties, good biocompatibility, and high bioactivity, which ensures their wide applications and strong therapeutic potentials in drug delivery. Drug delivery systems (DDS) based on marine polysaccharides and modified marine polysaccharide molecules have emerged as an innovative technology for controlling drug distribution on temporal, spatial, and dosage scales. They can detect and respond to external stimuli such as pH, temperature, and electric fields. These properties have led to their wide application in the design of novel drug delivery systems such as hydrogels, polymeric micelles, liposomes, microneedles, microspheres, etc. In addition, marine polysaccharide-based DDS not only have smart response properties but also can combine with the unique biological properties of the marine polysaccharide base to exert synergistic therapeutic effects. The biological activities of marine polysaccharides and the design of marine polysaccharide-based DDS are reviewed. Marine polysaccharide-based responsive DDS are expected to provide new strategies and solutions for disease treatment.

Abstract
Multiple sclerosis (MS) is a chronic neurologic disease defined by inflammation and demyelination of the central nervous system (CNS) comes with variable degrees of axonal and neuronal damage. The efficacy of β-D-Mannuronic acid (M2000) as a novel drug with immunosuppressive properties, patented (PCT/EP2017/067920), has been shown in experimental model of MS. In this study, the effects of M2000 on IL-1β, IL-17A, STAT1 and STAT3 gene expression and TLR2 and TLR4 molecules in secondary progressive MS (SPMS) patients have been evaluated. In this study, 14 SPMS patients and 14 healthy subjects (as control group) were entered from the phase 2 clinical trial (Clinical Trial identifier, IRCT2016111313739N6). The gene expression of IL-1β, IL-17A, STAT1 and STAT3 was assessed at the baseline and then measured after 6 months of therapy with M2000, by using quantitative real-time PCR method. Moreover, the expression of TLR2 and TLR4 molecules on peripheral blood mononuclear cell (PBMCs) were evaluated by flow cytometry method. The gene expression of IL-17A, STAT1 and STAT3 in MS patients decreased after six months of therapy with M2000 comparing before treatment. Also, the gene expression of IL-1β, decreased numerically after six months. Furthermore, the expression of TLR2 and TLR4 on PBMCs of the patients declined when compared to baseline. The results of this investigation revealed that M2000 could downregulate IL-17, STAT1 and STAT3 genes in SPMS patients and also reduce the expression of TLR2 and TLR4 on PBMCs. Moreover, M2000 declined numerically IL-β gene expression. This article is protected by copyright. All rights reserved.

Abstract
The preparation of bioactive polymeric molecules requires the attention of scientists as it has a potential function in biomedical applications. In the current study, functional substitution of alginate with a benzoyl group was prepared via coupling its hydroxyl group with benzoyl chloride. Fourier transform infrared spectroscopy indicated the characteristic peaks of aromatic C=C in alginate derivative at 1431 cm−1. HNMR analysis demonstrated the aromatic protons at 7.5 ppm assigned to benzoyl groups attached to alginate hydroxyl groups. Wetting analysis showed a decrease in hydrophilicity in the new alginate derivative. Differential scanning calorimetry and thermal gravimetric analysis showed that the designed aromatic alginate derivative demonstrated higher thermo-stability than alginates. The aromatic alginate derivative displayed high anti-inflammatory properties compared to alginate. Finally, the in vitro antioxidant evaluation of the aromatic alginate derivative showed a significant increase in free radical scavenging activity compared to neat alginate against DPPH (2,2-diphenyll-picrylhydrazyl) and ABTS free radicals. The obtained results proposed that the new alginate derivative could be employed for gene and drug delivery applications.

Abstract
Multiple sclerosis (MS) is described as a chronic inflammatory, demyelinating disease of the central nervous system on an autoimmune basis, which is the most frequent reason for nontraumatic disability in youth. The efficacy and safety of β-D-nannuronic acid (M2000) as a novel immunosuppressive drug (patented PCT/EP2017/067920) has been shown in an experimental model of MS and also in a phase 2 clinical trial. The effects of M2000 on SOCS1, SOCS3, TRAF6, and SHIP1 gene expression and also serum levels of IL-6 and TNF-α in secondary progressive multiple sclerosis patients have been assessed in this study. In this study, 14 secondary progressive multiple sclerosis patients and 14 healthy subjects (as the control group) were recruited from the phase 2 clinical trial (Clinical Trial identifier, IRCT2016111313739N6). Gene expression of SOCS1, SOCS3, TRAF6, and SHIP1 was measured at baseline and after 6 months of therapy with M2000 using a quantitative real-time polymerase chain reaction method. Furthermore, the serum levels of IL-6 and TNF-α were assessed by the enzyme-linked immunosorbent assay method. Our results showed that the gene expression of SOCS1, SOCS3, and SHIP1 was increased after 6 months of therapy with M2000 in MS patients. Moreover, the serum levels of IL-6 and TNF-α of patients declined compared with baseline, but this was not statistically significant. The results of this study demonstrated that M2000, with immunosuppressive properties, could upregulate SOCS1, SOCS3, and SHIP1 genes in patients with secondary progressive multiple sclerosis.

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.

Abstract
BACKGROUND The β-D-Mannuronic acid (M2000) as a novel immunosuppressive drug, patented (PCT/EP2017/067920), has shown positive effects in experimental model of multiple sclerosis (MS). In this study, our aim was to assess efficacy and safety outcomes in MS treated patients with mannuronic acid compared to the conventional drug. METHODS In a 6-month, randomized controlled, phase II trial, we enrolled patients who had secondary progressive multiple sclerosis (SPMS), were 21-54 years of age, with a score of 1-7 on the Expanded Disability Status Scale (EDSS), and who had at least one relapse in the previous 6 months. Patients were administered orally 1000 mg/day (two 500 mg/capsule daily) of M2000. Endpoints included changes in brain magnetic resonance imaging (MRI) measures and the EDSS score, as compared to the conventional drug (interferon beta-1a, interferon beta-1b). RESULTS A total of 25 (92.5%) of the M2000 treated patients and 25 conventionally treated patients completed the study. M2000 had better performance compared to the conventional drug regarding to MRI-related measurements, however, the differences between groups were not statistically significant. M2000 decreased the disability progression over the 6-month period. The EDSS score was decreased in the M2000 treated group in the sixth month versus the conventional drug (p < 0.009). Furthermore, we did not observe any short-term side effects. CONCLUSIONS As compared with the conventional drug, mannuronic acid (M2000) improved the rate of disability progression. This clinical trial demonstrated the efficacy and safety of mannuronic acid in patients with SPMS. (Registered Clinical Trials number, IRCT2016111313739N6).

Abstract
Alginate is a natural polysaccharide present in various marine brown seaweeds. Alginate oligosaccharide (AOS) is a degradation product of alginate, which has received increasing attention due to its low molecular weight and promising biological activity. The wide-ranging biological activity of AOS is closely related to the diversity of their structures. AOS with a specific structure and distinct applications can be obtained by different methods of alginate degradation. This review focuses on recent advances in the biological activity of alginate and its derivatives, including their anti-tumor, anti-oxidative, immunoregulatory, anti-inflammatory, neuroprotective, antibacterial, hypolipidemic, antihypertensive, and hypoglycemic properties, as well as the ability to suppress obesity and promote cell proliferation and regulate plant growth. We hope that this review will provide theoretical basis and inspiration for the high-value research developments and utilization of AOS-related products.

Abstract
The discovery of hematologic improvement and bone marrow modification by the drug β-D mannuronic acid (M2000) during treatment of rheumatoid arthritis in phase 1/2/3 clinical trials prompted us to design a new trial to target hematologic deficits in myelodysplastic syndromes (MDS). In this open-label, randomized phase 2 clinical trial, the potential effect and tolerability of drug M2000 was assessed in patients with low- and intermediate-1-risk MDS. The primary efficacy end point was hematologic improvement after 12 weeks of β-D-mannuronic acid therapy. Among 34 enrolled patients, half received their conventional therapy plus β-D-mannuronic acid, and the other half received only conventional drugs. In the conventional + β-D mannuronic acid treatment group, hematologic improvement and development of transfusion independence and/or reduction in transfusion requirements were seen in 12 patients (92.3%) and 1 patient (7.7%), respectively. Moreover, 5 patients (38.5%), 2 patients (15.4%), and 1 patient (7.7%) in the β-D-mannuronic acid-treated group showed hematologic improvement of the major parameters of erythroid, neutrophil, and platelet responses, respectively, based on the International Working Group criteria), whereas in the conventional treatment group as control, no hematologic improvements including erythroid, neutrophil, and platelet response was seen. In this trial, the addition of β-D mannuronic acid to conventional treatment showed promising results in MDS patients with low and intermediate-1 risk with effects on hematologic improvements without significant adverse effect.

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.

Effect of β-D-Mannuronic Acid (M2000) on Oxidative Stress Enzymes' Gene Using Healthy Donor Peripheral Blood Mononuclear Cells for Evaluating the Anti-Aging Property. Curr Drug Discov Technol 2019; 16:265-271. [PMID: 29766814 DOI: 10.2174/1570163815666180515122834] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2018] [Revised: 05/07/2018] [Accepted: 05/07/2018] [Indexed: 12/14/2022]
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 The oral administration of drug β-D-mannuronic acid (M2000) showed a potent therapeutic effect in phase I/II study in rheumatoid arthritis (RA) patients. Here, our aim is to assess the efficacy and safety of this new drug in RA patients under a multinational, randomized placebo-controlled phase III clinical trial. METHOD Patients (n = 288) with active disease at baseline and inadequate response to conventional drugs were randomly allocated to three groups; (1) receiving mannuronic acid at a dose of two capsules (500 mg) per day orally for 12 weeks, (2) placebo-controlled, and (3) conventional. The primary endpoints were the America College of Rheumatology 20 response (ACR20), 28-joint disease activity score (DAS28) and Modified Health Assessment Questionnaire-Disability Index (M-HAQ-DI). In addition, the participants were followed-up for safety assessment. RESULTS In this phase III trial, after 12 weeks of treatment, there was a significant reduction in ACR20 between mannuronic-treated patients compared to placebo and conventional groups. Moreover, there was a similar significant improvement for DAS28 following mannuronic therapy. The statistical analysis showed a significant reduction in the swollen and tender joint count in mannuronic-treated patients compared with the placebo group. On the other side, mannuronic acid showed no-to-very low adverse events in comparison to placebo. CONCLUSION The results of this multinational, phase III clinical trial provided a potent evidence base for the use of β-D-mannuronic acid as a new highly safe and efficient drug in the treatment of RA.

Abstract
OBJECTIVE This investigation evaluates the pro-apoptotic and anti-inflammatory effects of β-D-mannuronic acid [M2000] compared to diclofenac, based on gene expression involved in apoptosis and inflammation process [including Bcl2, NFκB, IL-8 and Cd49d] in Peripheral Blood Mononuclear Cells [PBMCs] of healthy donors under exvivo conditions. MATERIALS The venous blood samples of twelve healthy volunteers with aged 25-60 years were collected in heparinized tubes. The healthy volunteers were selected from no smoking group and without using illicit drugs and suffering from diabetes. The PBMCs were separated and divided into untreated and treated groups. METHODS The PBMCs of each sample were cultured in 5 wells of culture plate, so that the first well consisted of 2×106 cells exposed by LPS-EB [1μg/ml] to stimulate PBMCs and absence of M2000 [untreated well]. The second, third, fourth and fifth wells containing 2×106 cells/well and LPS-EB, after 4 hours incubation at 37ºC, received 5, 25 and 50 μg/well of M2000 and 5 μg/well of diclofenac, respectively as treated group. RESULTS The PBMCs were separated and RNAs were then extracted and cDNAs synthesized and gene expression levels were assessed by qRT-PCR. Furthermore, we studied whether M2000 is able to facilitate apoptosis in PBMCs. Our findings represent that the high dose of M2000 could significantly decrease the expression level of NFκB gene compared to untreated group (p < 0.0002). On the other hand, no significant change was observed in treated cells with diclofenac. All doses of M2000 could significantly augment apoptosis compared to untreated group [p < 0.0001]. Additionally, we observed the same apoptotic effects between the medium dose of M2000 and diclofenac. Besides, no significant reduction was shown in expression levels of IL8, Bcl2 and Cd49d genes in all doses of M2000 and diclofenac compared to untreated group. This experiment demonstrates M2000 as a new effective NSAID with immunosuppressive characteristics capable of stimulating apoptosis through lowering expression levels of NFκB gene, which might be probably considered as an appropriate drug for reducing the risk of developing inflammatory diseases and cancer.

Abstract
BACKGROUND Following the potent efficacy of β-D-mannuronic acid (M2000) in phase I/II trial in ankylosing spondylitis patients, the present clinical trial was conducted to evaluate the efficacy, safety, and tolerability of this novel drug in rheumatoid arthritis (RA) patients who had inadequate response to conventional therapy. METHOD The study was a 12-week randomized, controlled, phase I/II clinical trial with two treatment arms: M2000 and conventional treatment. Patients who had RA according to the modified American College of Rheumatology (ACR) criteria, with active disease at baseline also inadequate response to conventional therapy, were enrolled in this study. M2000 was administrated at a dose of two capsules (500 mg) per day orally during a period of 12 weeks. The primary endpoint was the proportion of patients fulfilling the ACR 20% improvement criteria after 12 weeks of M2000 therapy. Moreover, the patients were also followed up for safety. RESULTS There were no statistically significant differences between treatment and conventional groups at baseline characteristics. The ACR20 response rate was significantly higher among M2000-treated patients than conventional-treated control, so that 74% of patients in treatment group showed an ACR20 response after 12 weeks of M2000 therapy (74 versus 16%; P = 0.011). 10% of M2000-treated patients and 57.1% of conventional-treated patient's adverse events occurred during this study. CONCLUSION Treatment with M2000 in combination with conventional therapy showed a significantly superior efficacy along with a high safety profile compared to conventional-treated patients. Thereby, M2000 might be suggested as a suitable option in the treatment of RA.

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 The anti-aging property of β-D-mannuronic acid (M2000) as a novel non-steroidal anti-inflammatory and immunosuppressive agent was investigated on several determinants relative to the oxidative stress in an animal model. METHODS Sprague-Dawley rats were used for evaluating the safety and efficacy properties of M2000 on some oxidative stress enzymes, including the following: mitochondrial superoxide dismutase (SOD2), catalase (CAT), glutathione peroxidase (GPX1), glutathione S-transferase (GST), myeloperoxidase (MPO), and inducible nitric oxide synthase (iNOS) gene expression by real-time PCR. Malondialdehyde (MDA), carbonyl protein (PCO) (the lipid and protein oxidation marker, respectively), and total antioxidant capacity (TAC) were tested in serum by biochemical analysis. In addition, cortisol as a steroid hormone was surveyed by chemiluminescence immunoassay after 12 weeks of M2000 consumption. The rats were sacrificed 3 months after daily oral administration of M2000. RESULTS Our findings revealed the favorable effects of M2000 on several antioxidant enzyme and gene expression, including SOD2, CAT, GPX1, and GST; however, our results were not statistically significant. Moreover, there was no significant difference in MDA and PCO as lipid and protein oxidation markers, TAC, and cortisol compared with the control group following M2000 consumption. A slight weight increase in the M2000-treated group was also observed. CONCLUSIONS Our data showed the anti-aging property of M2000 as a novel designed non-steroidal anti-inflammatory drug (NSAID) with immunosuppressive property on various oxidative stress determinants.

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.

Abstract
OBJECTIVE To evaluate the efficacy, safety and tolerability of β-d-mannuronic acid (M2000) in the treatment of ankylosing spondylitis (AS). METHODS The study was a 12-week randomized, double-blind, placebo-controlled, phase I/II clinical trial with 3 treatment arms: placebo, β-d-mannuronic acid and naproxen. Patients who had AS according to the modified New York criteria, with active disease at baseline were eligible for study. Primary outcome measure was the Assessment of SpondyloArthritis international Society (ASAS) 20 response rate at week 12. RESULTS Of the 85 randomized patients, 27 were allocated to receive placebo, 28 naproxen, and 30 β-d-mannuronic acid. There were no statistically significant differences between treatment groups at baseline. Of the patients receiving β-d-mannuronic acid, 57.7% achieved an ASAS20 response at week 12, compared with 59% of the patients in the naproxen group (P>0.05) and 19% of the patients in the placebo group (P=0.007). In comparison with patients receiving placebo over the 12-week treatment period, those receiving β-d-mannuronic acid and naproxen demonstrated statistically significantly greater improvement in all secondary endpoints. Interestingly, β-d-mannuronic acid reduced some parameters associated with inflammation more effectively than naproxen and placebo. The incidence of gastrointestinal and other adverse events were higher on naproxen than on β-d-mannuronic acid and placebo. CONCLUSION The present study demonstrated similar efficacy, but with a more favorable safety profile for β-d-mannuronic acid than naproxen and, therefore, suggest that β-d-mannuronic acid is suitable for the management of AS.

Abstract
Ankylosing spondylitis (AS) is a chronic inflammatory rheumatic disease characterized by the inflammation of sacroiliac joints and axial skeleton. A combination of genetic, environmental and immunological factors are involved in AS's pathogenesis. TLRs are type I transmembrane glycoproteins that play a crucial role in the innate immune responses against invading pathogens. Observational studies have demonstrated a possible association between TLR dysregulation and AS. The β-d-mannuronic acid (M2000), as a novel NSAID with immunosuppressive property, has shown an inhibitory effect on Toll-like receptor (TLR) 2, 4 signaling in HEK293 cells. In the present study, we investigated the gene expression of Myd88, IKB-alpha, NF-kB and MAPK14 (genes of the TLR/NF-kB Signaling Pathway) in AS patients in comparison to healthy subjects and also the effect of β-d-mannuronic acid on disease activity and mRNA expression of these molecules in affected patients. We showed for the first time that the gene expression level of Myd88, IKB-alpha, NF-kB and MAPK14 was higher in AS patients in comparison to healthy subjects. Moreover we confirmed that the β-d-mannuronic acid not just reduced significantly the disease activity of AS individuals compared to placebo, but also it could significantly decrease the expression level of genes associated with TLR/NF-kB Signaling Pathway in treated patients with M2000. These results may provide a new therapeutic approach to attenuate inflammatory responses in AS patients, (Identified; IRCT 2013062213739N1).

Abstract
Rheumatoid arthritis (RA) is the most common form of chronic inflammatory arthritis characterized by pain, swelling and destruction of joints, with a resultant disability. Disease-modifying anti-rheumatic drugs (DMARDs) and biological drugs can interfere with the disease process. In this study, the effect of β-d-mannuronic acid (M2000) as a novel non-steroidal anti-inflammatory drug (NSAID) with immunosuppressive and anti-inflammatory effects together with antioxidant effects was evaluated on IL17, RORγt, IL4 and GATA3 gene expression in 12 RA patients. Previously, M2000 driven from sodium alginate (natural product; patented, DEU: 102016113018.4) has shown a notable efficacy in experimental models of multiple sclerosis, RA and nephrotic syndrome. This study was performed on 12 patients with RA who had an inadequate response to conventional treatments. During this trial, patients were permitted to continue the conventional therapy excluding NSAIDs. M2000 was administered orally at a dose of 500 mg twice daily for 12 weeks. The peripheral blood mononuclear cells (PBMCs) were collected before and after treatment to evaluate the expression levels of IL4, GATA3, IL17 and RORγt. The gene expression results showed that M2000 has a potent efficacy, so that it could not only significantly decrease IL17 and RORγt levels but also increase IL4 and GATA3 levels after 12 weeks of treatment. Moreover, the gene expression results were in accordance with the clinical and preclinical assessments. In conclusion, M2000 as a natural novel agent has therapeutic and immunosuppressive properties on RA patients (identifier: IRCT2014011213739N2).

Abstract
Metastasis is the main cause of death in breast cancer patients. Inflammatory processes following crosstalk between tumor cells and tumor microenvironment play an important role in progression and metastasis of cancer. Hence, targeting of these interactions may represent a novel promising strategy for breast cancer therapy. So, we investigated the effects of β-D mannuronic acid (BDM), a new antiinflammatory agent, on 4T1 breast cancer cell line both in vitro and in vivo. Proliferation assays revealed low-cytotoxic effect of BDM on 4T1 cells. However, BDM reduced activity of MMP-2, MMP-9 and significantly decreased the adhesion of 4T1 cells to extracellular matrix (ECM) in a dose-dependent manner. The in vivo results demonstrated that BDM strongly inhibits tumor growth and increases lifespan as compared with control mice. The decrease in tumor mass was associated with decreased metastasis, recruitment, and frequency of inflammatory cells in tumor tissue. Our preclinical findings demonstrated that BDM therapy not only prevents formation of chronic inflammatory response but also inhibits crosstalk between tumor cells and their microenvironment, which is associated with reduction of tumor growth and metastasis arrest. Our data imply the use of BDM therapy in future clinical trials to open a new horizon for breast cancer therapy.

Abstract
The d-mannuronic acid (M2000) is a novel nonsteroidal anti-inflammatory drug that has immunosuppressive effects together with antioxidant property. M2000 has shown a notable efficacy in experimental models of multiple sclerosis, rheumatoid arthritis, and nephrotic syndrome. In this work, the effect of M2000 on the treatment of Alzheimer's disease (AD) was performed by Morris water maze experiment, and the immunological assessments were carried out by Western blot, apoptosis (procaspase-3, Bax/Bcl2, P53), enzymatic (superoxide dismutase [SOD]), and nonenzymatic oxidative stress (malondialdehyde [MDA]) tests. We found that pretreatment of AD in the rat model by M2000 had a potent efficacy on rat behavior and also it led to a significant inhibition of amyloid plaque production. Moreover, our data showed that M2000 can reduce the amount of Bax/Bcl2, P53, MDA, and SOD, as well as it normalized the level of procaspase-3. Our results suggest M2000 is a potential therapeutic agent for the treatment of AD.

Abstract
BACKGROUND Impaired expression and function of microRNAs (miRNAs) are involved in the pathogenesis of many autoimmune and inflammatory diseases. Moreover, there is a close relationship between TLRs and miRNAs and impairment in regulating their expression which can play a vital role in the immunopathogenesis of many inflammatory reactions. This research aimed to study the pharmaceutical effects of M2000 (β-d-mannuronic acid) on the expression of miR-146a and its two target molecules (IRAK1 and TRAF6), and the transcription factor NF-κB in the HEK-Blue hTLR2 cell line. METHODS The cytotoxicity of M2000 was assessed by the MTT assay, and the qRT-PCR technique was employed in the presence and absence of M2000 treatment to measure gene-expression levels of miR-146a, IRAK1, TRAF6, and NF-κB. RESULTS MTT assay indicated that M2000 (before the concentration of 500μg/ml) had no cytotoxic effect on HEK-Blue hTLR2 cells. Our results showed that M2000 at low and high doses (5 and 25μg/well) could significantly reduce gene expression levels of miR-146a (p<0.01). Furthermore, it was found that this medication at two different doses could considerably decrease IRAK1 and TRAF6 gene expression (p<0.001). Moreover, this study revealed that expression level of NF-κB also significantly declined at these two doses (p<0.01). CONCLUSIONS This study for the first time shows that M2000 as a novel NSAID with immunosuppressive properties is able to modify TLR signaling through suppressing the adaptor molecules IRAK1 and TRAF6, the transcription factor NF-κB and miR-146a as a new therapeutic approach.

Abstract
CONTEXT β-d-Mannuronic acid (M2000) has shown its therapeutic effects with the greatest tolerability and efficacy in various experimental models such as experimental autoimmune encephalomyelitis (EAE), adjuvant induced arthritis (AIA), nephrotic syndrome, and acute glomerulonephritis. Despite pharmacological effects of β-D-mannuronic acid, there have been no systematic toxicological studies on its safety so far. OBJECTIVE The study was designed to determine the acute and subchronic toxicity of β-D-mannuronic acid, an anti-inflammatory agent, in healthy male NMRI mice and Wistar rats, respectively. MATERIALS AND METHODS For the acute toxicity study, the animals received orally five different single doses of β-D-mannuronic acid and were kept under observation for 14 d. In the subchronic study, 24 Wistar male rats were divided into four groups and were treated orally (gavage) once daily with test substance preparation at dose levels of 0, 50, 250, and 1250 mg/kg body weight for at least 63 consecutive days (9 weeks). Mortality, clinical signs, body weight changes, hematological and biochemical parameters, gross findings, organ weights, and histopathological determinations were monitored during the study. RESULTS The results of acute toxicity indicated that the LD50 of β-D-mannuronic acid is 4.6 g/kg. We found no mortality and no abnormality in clinical signs, body weight, relative organ weights, or necropsy in any of the animals in the subchronic study. Additionally, the results showed no significant difference in hematological, biochemical, and histopathological parameters in rats. CONCLUSIONS Our results suggest that β-D-mannuronic acid is relatively safe when administered orally in animals.

Skimmin, a Coumarin from Hydrangea paniculata, Slows down the Progression of Membranous Glomerulonephritis by Anti-Inflammatory Effects and Inhibiting Immune Complex Deposition. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2013; 2013:819296.

Abstract
Skimmin is one of the major pharmacologically active molecules present in Hydrangea paniculata, a medical herb used in the traditional Chinese medicine as an anti-inflammatory agent. In the current study, we attempted to investigate its renoprotective activity and underlying mechanisms in a rat model of membranous glomerulonephritis induced by cationic bovine serum albumin (c-BSA). Sprague-Dawley (SD) rats were divided into five groups, including normal control, model control, Mycophenolate Mofetil-treated group, and two skimming-treated groups (15 mg/kg and 30 mg/kg). Our research showed that treatment with skimmin significantly reduced the levels of blood urea nitrogen (BUN), urinary albumin excretion (UAE), and serum creatinine (Scr) as compared with model control after experimental induction of membranous glomerulonephritis (P < 0.01). Moreover, glomerular hypercellularity, tubulointerstitial injury, and glomerular deposition of IgG were less intense after skimmin treatment. By immunochemistry analysis, we demonstrated that skimmin could significantly inhibit interleukin-1 β (IL1 β ) and IL-6 expression (P < 0.05), reduce the loss of nephrin and podocin, and suppress the infiltration of renal interstitium by CD3-positive T cell and CD20-positive B cell. These results suggest that treatment with skimmin can significantly improve renal function and suppress the IgG deposition as well as the development of glomerular lesions in a rat model of membranous glomerulonephritis.
