Abstract
Copper-related reactive oxygen species (ROS) formation can lead to neuropathologic degradation associated with Alzheimer's disease (AD) according to amyloid cascade hypothesis. A complexing agent that can selectively chelate with copper ions and capture copper ions from the complex formed by copper ions and amyloid-β (Cu - Aβ complex) may be available in reducing ROS formation. Herein, we described applications of guluronic acid (GA), a natural oligosaccharide complexing agent obtained from enzymatic hydrolysis of brown algae, in reducing copper-related ROS formation. UV-vis absorption spectra demonstrated the coordination between GA and Cu(II). Ascorbic acid consumption and coumarin-3-carboxylic acid fluorescence assays confirmed the viability of GA in reducing ROS formation in solutions containing other metal ions and Aβ. Fluorescence kinetics, DPPH radical clearance and high resolution X - ray photoelectron spectroscopy results revealed the reductivity of GA. Human liver hepatocellular carcinoma (HepG2) cell viability demonstrated the biocompatibility of GA at concentrations lower than 320 μM. Cytotoxic results of human neuroblastoma (SH-SY5Y) cells verified that GA can inhibit copper-related ROS damage in neuronal cells. Our findings, combined with the advantages of marine drugs, make GA a promising candidate in reducing copper-related ROS formation associated with AD therapy.

Abstract
The prevention of disease and infection requires immune systems that operate effectively. This is accomplished by the elimination of infections and abnormal cells. Immune or biological therapy treats disease by either stimulating or inhibiting the immune system, dependent upon the circumstances. In plants, animals, and microbes, polysaccharides are abundant biomacromolecules. Due to the intricacy of their structure, polysaccharides may interact with and impact the immune response; hence, they play a crucial role in the treatment of several human illnesses. There is an urgent need for the identification of natural biomolecules that may prevent infection and treat chronic disease. This article addresses some of the naturally occurring polysaccharides of known therapeutic potential that have already been identified. This article also discusses extraction methods and immunological modulatory capabilities.

Abstract
INTRODUCTION Recently, the coronavirus disease 2019 (COVID-19) infection, with a vast spectrum of clinical and paraclinical symptoms has been a major health concern worldwide. Therapeutical management of COVID-19 includes antiviral and anti-inflammatory drugs. NSAIDs, as the second-line therapy, are often prescribed to relieve the symptoms of COVID-19. The α-L-guluronic acid (G2013) is a non-steroidal patented (PCT/EP2017/067920) agent with immunomodulatory properties. This study investigated the effect of G2013 on the outcome of COVID-19 in moderate to severe patients. METHODS The disease's symptoms were followed up during hospitalization and for 4 weeks postdischarge in G2013 and control groups. Paraclinical indices were tested at the time of admission and discharge. Statistical analysis was performed on clinical and paraclinical parameters and ICU admission and death rate. RESULTS The primary and secondary outcomes indicated the efficiency of G2013 on COVID-19 patients' management. There were significant differences in the duration of improvement of fever, coughing, fatigue/malaise. Also, a comparison of paraclinical indices at the time of admission and discharge showed significant change in prothrombin, D-dimer, and platelet. As the main findings of this study, G2013 significantly decreased the percentage of ICU admission (control:17 patients, G2013:1 patient) and death (control: 7 cases, G2013:0). CONCLUSION These results conclude that G2013 has sufficient potential to be considered for moderate to severe COVID-19 patients, can significantly reduce the clinical and physical complications of this disease, has a positive effect on modulating the coagulopathy process, and aids in saving lives.

Abstract
α-l-Guluronic acid (ALG; G2013) has been previously introduced as a new anti-inflammatory agent with promising therapeutic effects. Thus, in the present study, we aimed to evaluate the acute and sub-acute toxicity of ALG through intravenous (i.v.) administration in Balb/C mice. ALG was administrated i.v. to the mice with doses of 300, 600, and 1000 mg/kg of body weight to investigate acute toxicity (single dose) and with doses of 25, 50, and 100 mg/kg of body weight to sub-acute toxicity study (daily injections for a period of 28 days). The mortality rate, food and water intake, behavior, body weight, gross necropsy, hematological and biochemical parameters as well as histopathological presentations of the vital organs (kidneys, liver, lungs, spleen, and heart) were examined in treated groups and compared to the healthy controls. The results of both acute and sub-acute studies showed that i.v. administrations of ALG did not affect the investigated parameters in both sexes, indicating that the LD50 of ALG was higher than 1000 mg/kg of body weight. As no difference was observed in toxicity profiles of investigated doses, no-observed-adverse-effect-level for i.v. administration of ALG in the sub-acute study was greater than 100 mg/kg body weight in both female and male mice. According to the finding, i.v. administration of ALG did not lead to any clinical sign in abovementioned doses, suggesting that ALG was well tolerated up to 1000 mg/kg. These pre-clinical findings support the application of ALG in the future clinical trials.

Abstract
Given multiple treatment strategies for prostate cancer, its mortality rate is still high; therefore, novel treatment strategies seem necessary. G2013 or α-L-guluronic acid is a new patented drug with immunomodulatory and anti-inflammatory properties. This study aimed to evaluate the property of G2013 on inflammatory molecules involved in tumorigenesis of prostate cancer. MTT assay was used to assess the effect of the drug on the proliferation of PC-3 cells. Expression of interleukin 8 (IL-8), Nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB), myeloid differentiation factor 88 (MYD-88), cyclooxygenase 2 (COX-2), matrix metalloproteinase-2 (MMP-2), and MMP-9 genes were studied in the PC-3 cells treated with 25 (low dose) or 50 (high dose) µg/mL of G2013 for 24 h using quantitative real-time polymerase chain reaction (qRT-PCR) technique. Protein expression of NF-κB and protein activities of MMP-2 and MMP-9 were assayed using flow cytometry and gelatin zymography, respectively. The expression of COX-2 (p = 0.007 at low dose), MMP-2 (p = 0.023 at low dose, p = 0.002 at high dose), NF-κB (p = 0.004 at low dose) and IL-8 (p < 0.0001 in both doses) genes, NF-κB protein (p < 0.0001 in both doses), and MMP-2 activity (p < 0.0001 in both doses) were significantly reduced in the presence of G2013 as compared to the control group. Cancer cell proliferation was also inhibited under 10-500 µg/mL G2013 treatment. Our results revealed that G2013 has the potential to inhibit PC-3 cell proliferation and reduce the expression of tumour-promoting mediators, COX-2, MMP-2, NF-κB, and IL-8 involved in the progression and metastasis of prostate cancer.

Abstract
BACKGROUND Nonalcoholic Steatohepatitis (NASH) results from the accumulation of fatty acids in the liver. The elevated production of pro-inflammatory factors is the reason for the hyper inflammation in NASH. The α-L-Guluronic acid (G2013), a new member of NSAID family, is a plant-originated agent with immunomodulatory properties. The current study investigated the effects of G2013 on inflammatory factors in PBMCs of NASH patients. METHODS PBMCs of 14 NASH patients and 14 healthy controls were isolated and cultured. The patient's cells were treated with low (5 µg/mL) and moderate (25 µg/mL) doses of G2013 alongside the diclofenac optimum dose (3 µg/mL). The expression and secretion levels of variables were assessed by real-time PCR and ELISA, respectively. RESULTS Findings indicated that the expression levels of TLR4 and NF-κB, as well as the secretion levels of TNF-α and IL-6 cytokines, were significantly elevated in NASH patients compared to healthy individuals. The expression levels of TLR4 and NF-κB were strikingly downregulated in treated cells of patients in both low and moderate doses of G2013. A considerable reduction was obtained in the secretion level of IL-6 using both low and moderate doses of G2013 and in the secretion level of TNF-α using the moderate dose of G2013. CONCLUSION The results indicated that G2013 could meaningfully decrease the expression and secretion levels of evaluated factors (TLR4, NF-κB, TNF-α, and IL-6) in PMBCs of NASH cases. Since there is no effective treatment for NASH patients, we hope that G2013 would be a promising immunomodulatory agent in reducing inflammation and improvement of patients.

Abstract
Ankylosing spondylitis (AS) is a chronic autoimmune arthritis disease with a genetic background, affecting the skeletal axis, sacroiliac, and peripheral joints. Nonsteroidal anti-inflammatory drugs (NSAIDs) are the first-line treatment for AS to alleviate the inflammation and pain. Despite the beneficial effect, their use is accompanied by a wide variety of possible side effects in the gastrointestinal and kidneys. The α-l-guluronic acid (G2013) is a new nonsteroidal anti-inflammatory patented (PCT/EP2017/067920) drug, which has shown its anti-inflammatory properties in the previous investigations. The present study revealed the oral administration effect of G2013 on COX-1 and COX-2 gene expression in AS patients. The blood samples of twelve 18-45 years old patients suffering AS and BASDAI >4, and BASFI >4, before and after 12 weeks of treatment with G2013 and 12 blood samples of healthy volunteers were collected and the effect of G2013 on the gene expression of COX-1 and COX-2 enzymes were assessed by Real-Time PCR. The results indicate that G2013 is able to reduce the gene expression level of COX-1 and COX-2 enzymes in treated AS patients compared to healthy control. Statistically significant differences were not observed between the treatment and the healthy control groups. According to the findings, G2013 might be categorized and introduced as a novel NSAID for the treatment of AS.

Abstract
The α-L-guluronic acid (G2013), is a novel immunosuppressive drug (PCT/EP2017/067920). One of the most popular ideas in designing drugs for multiple sclerosis (MS) is to restrict the main inflammation-related lymphocytes and cytokines. The foremost problems with conventional drugs are their side effects and low efficacy. In order to rectify these problems, we examined the effect of two doses of G2013 on the gene expression of IFN-γ, IL-17, IL-22, T-bet, RORC, and AHR, in MS patients PBMCs. RNA was extracted from peripheral blood mononuclear cell (PBMC) of 12 relapsing-remitting MS patients and 12 healthy volunteers and the effect of two doses of G2013 on the gene expression of IFN-γ, IL-17, IL-22, T-bet, RORC, and AHR, were assessed by real-time PCR. Overall, the results show that G2013 is able to significantly reduce the gene expression of IL-22, AHR, RORC, and T-bet. Collectively, G2013 might be considered and studied as a new drug of possible use to MS patients due to its immunosuppressive property on some of the main inflammatory cytokine and transcription factors.

Abstract
Aim: Rheumatoid arthritis (RA) is a prevalent inflammatory, autoimmune diseases characterized by inflammation and destruction of joints. Disease-modifying anti-rheumatic drugs (DMARDs) and biological drugs can have modulatory interference in disease process. In this study, the effect of Guluronic Acid (G2013) as a novel non-steroidal anti-inflammatory drug (NSAID) with immunomodulatory effects was evaluated on IL-17, RORγt, IL-4 and GATA-3 gene expression in RA patients.Methods: Fourteen patients with RA who had an inadequate response to conventional treatments were included in this clinical trial. During this trial, patients were permitted to continue the conventional therapy excluding NSAIDs. G2013 was administered orally at dose of 500 mg twice daily for 12 weeks. The peripheral blood mononuclear cells (PBMCs) were collected before and after treatment to evaluate the gene expression levels of IL-4, GATA-3, IL-17 and RORγt.Results: Primary and secondary efficacy endpoints and Disease Activity Score (DAS) 28 showed an improvement after 12 weeks of treatment. G2013 has a potent efficacy on gene expression of these molecules, so that it could decrease IL-17 and RORγt levels and increase IL-4 and GATA-3 levels after 12 weeks of treatment. Reduction of IL-17 was statistically non-significant whereas for its transcription factor (RORγt) was statistically significant. Moreover, the gene expression results were in accordance with the clinical and preclinical assessments.Conclusion: G2013 as a natural novel drug showed a significant increase on IL-4 and GATA-3 and a significant decrease on RORγt gene expression after 12 weeks oral administration of this drug in RA patients.

Abstract
BACKGROUND This study aimed to investigate the effects of guluronic acid (G2013) on blood sugar, insulin, and gene expression profile of oxLDL receptors (SR-A, CD36, LOX-1, and CD68) in the experimental model of diabetes. METHODS 18 Sprague Dawley rats were randomly assigned to three groups of healthy control, diabetic control, and G2013 group. Diabetes was induced through intraperitoneal (IP) injection of 60 mg/kg streptozotocin. The subjects were IP treated with 25 mg/kg of G2013 per day for 28 days. The body weight, food intake, fasting blood glucose and insulin were measured. In addition, the expression of mentioned genes was investigated through quantitative real-time PCR. RESULTS The data showed that the final weight increased significantly in the G2013-treated subjects compared to the diabetic control (p < 0.05). The results indicated that final food intake significantly reduced in the G2013-treated subjects compared to the diabetic control (p < 0.05). The study findings also suggested that the final fasting blood glucose significantly reduced in the G2013-treated group, whereas the final fasting serum insulin level significantly increased in this group compared to the diabetic control (p < 0.05). Moreover, the gene expression levels of SR-A, CD36, LOX-1, and CD68 in the G2013 group significantly reduced compared to the diabetic control (p < 0.05). CONCLUSION This study showed that G2013, could reduce blood glucose and increase insulin levels and reduce the gene expression level of oxLDL receptors. In addition, it may probably play an important role in reducing the severity of diabetes-induced inflammatory symptoms.

Abstract
INTRODUCTION Inhibition of Toll-like receptors (TLRs) signaling plays a crucial role in suppressing the inflammation and available data presenting G2013 as an immunomodulatory agent, therefore, we designed this study to answer whether G2013 can affect the signaling pathway of TLR2 and TLR4. METHODS Cytotoxicity study of G2013 was performed by MTT assay. HEK293 TLR2 and HEK293 TLR4 cell lines were cultured and treated with low dose (5µg/ml) and high dose (25µg/ml) of G2013 for 24 hours. Gene expressions of MyD88, Tollip, and NF-κB were defined by quantitative real-time PCR. RESULTS The cytotoxicity assay showed that the concentrations lesser than 125μg/ml of G3012 had no apparent cytotoxicity, however, the concentrations of 5µg/ml and 25µg/ml could suppress the mRNA expression of MyD88, Tollip and NF-κB in HEK293 TLR2 and HEK293 TLR4 cell lines. CONCLUSION in our study, we verified the linkage between the immunosuppressive property of G2013 and TLR2, TLR4 signaling cascade; but so far, the specific target of G2013 and its molecular mechanism has not been detected yet. We recommend further studies on other Patten Recognition Receptors (PRRs)and other mechanisms of inflammation like oxidative stress to be conducted in the future.

Abstract
BACKGROUND The non-steroidal anti-inflammatory drugs (NSAIDs) play crucial role in the controlling of inflammatory diseases. Due to the vast side effects of NSAIDs, its use is limited. G2013 or α-L-Guluronic Acid is a new NSAID with immunomodulatory features. OBJECTIVES Considering the leading role of TLRs in inflammatory responses, in this study, we aimed to evaluate G2013 cytotoxicity and its effect on the expression of TLR2 and TLR4 molecules. METHODS HEK293-TLR2 and HEK293-TLR4 cells were cultured and seeded on 96-well cell plate, and MTT assay was performed for detecting the viability of the cells after treatment with different concentrations of G2013. HT29 cells were grown and treated with low and high doses of G2013. After total RNA extraction and cDNA synthesis, quantitative real-time PCR were performed to assess the TLR2 and TLR4 mRNA synthesis. RESULTS We found that concentrations of ≤125 µg/ml of G2013 had no apparent cytotoxicity effect on the HEK293-TLR2 and -TLR4 cells. Our results indicated that after G2013 treatment (5 µg/ml) in HT29 cells, TLR2 and TLR4 mRNA expression decreased significantly compared with the untreated control group (p=0.02 and p=0.001 respectively). CONCLUSION The results of this study revealed that G2013 can down regulate the TLR2 and TLR4 gene expression and exerts its inhibitory effect. Our findings are parallel to our previous finding which showed G2013 ability to down regulate the signaling pathway of TLRs. However, further studies are needed to identify the molecular mechanism of G2013.

Abstract
The innate immune response in the central nervous system (CNS) is implicated as both beneficial and detrimental to health. Integral to this process are microglia, the resident immune cells of the CNS. Microglia express a wide variety of pattern-recognition receptors, such as Toll-like receptors, that detect changes in the neural environment. The activation of microglia and the subsequent proinflammatory response has become increasingly relevant to synucleinopathies, including Parkinson's disease the second most prevalent neurodegenerative disease. Within these diseases there is evidence of the accumulation of endogenous α-synuclein that stimulates an inflammatory response from microglia via the Toll-like receptors. There have been recent developments in both new and old pharmacological agents designed to target microglia and curtail the inflammatory environment. This review will aim to delineate the process of microglia-mediated inflammation and new therapeutic avenues to manage the response.
