Abstract
Phenol-sulfuric acid method is one of the most common methods applied to the analysis of total sugar content during polysaccharides study. However, it was found that the results obtained from the phenol-sulfuric acid method was generally lower than the real total sugar content, especially when acidic monosaccharides were contained in the polysaccharides samples. Therefore, the present study focused to unveil the proposed problem. Based on the optimization of colorimetric conditions, such as optimal wave length of absorption, linearity range, color reaction time and temperature, it indicated that the phenol-sulfuric acid method was a convenient and accurate way for the total sugar content analysis. In addition, the color-rendering capabilities of 10 common monosaccharides were systematically analyzed to obtain a relative correction factor for each monosaccharide relative to glucose, which was proved to be the main reason for the deviation in the detection of total sugar content. Moreover, the key points during the application of phenol-sulfuric acid method were suggested. This study provides a scientific theoretical basis and a reliable experimental research method for the accurate determination of total sugar content by the phenol-sulfuric acid method, and which will also promote the application of this convenient method in the polysaccharides study.

Quantitative determination of dextran sulfate and pentosan polysulfate and their binding with protamine using chronopotentiometry with polyion-selective electrodes. Anal Chim Acta 2021; 1149:338208. [PMID: 33551060 DOI: 10.1016/j.aca.2021.338208] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2020] [Revised: 12/21/2020] [Accepted: 01/06/2021] [Indexed: 11/18/2022]
Abstract
We report for the first time a chronopotentiometric measurement of polyanions based on localized ion depletion at the sample/membrane interface at a characteristic transition time τ, using polymer membrane polyanion-selective electrodes. Chronopotentiometric transduction of polyions based on the measurement of transition time has analytically more attractive applications compared to the controlled-current reversible pulsed chronopotentiometric transduction based on electromotive force (emf) measurement. This is because traditional polyion-selective electrodes based on emf measurement intrinsically give nonlinear (sigmoidal) calibration curves. While these can be used for indirect determination of polyions via polyanion-polycation titrations, they are not convenient for direct quantitation. However, under chronopotentiometric measurement based on the measurement of transition time, the square root of the transition time τ is linearly related to the concentration of the polyion according to the Sand equation and can be used for a direct calibration-free rapid determination. In this work, we have measured the concentrations of dextran sulfate (DS) and pentosan polysulfate (PPS) using polyanion selective electrodes under chronopotentiometric method where the transition time was measured and controlled-current pulsed chronopotentiometric transductions, where the phase boundary potential (emf) was measured. In addition, the protamine-DS and the protamine-PPS binding ratios have been determined using both transductions. The protamine-PPS binding ratio was determined to be 1.51:1 by the titration method and 1.54:1 by chronopotentiometry. The protamine-DS binding ratio was determined to be 1.37:1 by the titration method and 1.41:1 by chronopotentiometry, showing excellent agreement between the two methods. These simple measurement methods of binding ratios between polysaccharides and polypeptides may become important tools for screening safer and more reliable antidotes for the newer and safer anticoagulants such as Low Molecular Weight Heparins(LMWHs) and also to determine the dosages of antidotes needed to neutralize the anticoagulant activity.

Abstract
Fucoidans are marine sulfated biopolysaccharides that have heterogenous and complicated chemical structures. Various sugar monomers, glycosidic linkages, molecular masses, branching sites, and sulfate ester pattern and content are involved within their backbones. Additionally, sources, downstream processes, and geographical and seasonal factors show potential effects on fucoidan structural characteristics. These characteristics are documented to be highly related to fucoidan potential activities. Therefore, numerous chemical qualitative and quantitative determinations and structural elucidation methods are conducted to characterize fucoidans regarding their physicochemical and chemical features. Characterization of fucoidan polymers is considered a bottleneck for further biological and industrial applications. Consequently, the obtained results may be related to different activities, which could be improved afterward by further functional modifications. The current article highlights the different spectrometric and nonspectrometric methods applied for the characterization of native fucoidans, including degree of purity, sugar monomeric composition, sulfation pattern and content, molecular mass, and glycosidic linkages.

Abstract
Fucoidans are a group of homo-and hetero-polysaccharides, which necessarily contains residues of sulfated α-L-fucose. Fucoidans are found only in brown algae. These polysaccharides exhibit a wide spectrum of biological activity and have a great therapeutic potential. Enzymes capable of catalyzing the degradation of fucoidans are absent in the mammalian enzyme system. The question arises: is the transformation of fucoidan in mammals, particularly in human possible? Studies in vivo (in situ) and in vitro have demonstrated that high molecular weight fucoidans are absorbed across rat intestinal epithelial cells, accumulated by liver macrophages, and characterized by low levels in blood and urine. Using the example of the Okinawa Prefecture (Japan) residents, it was shown that Cladosiphon okamuranus alga is digested and the fucoidan contained in this alga is absorbed in the human body.

Abstract
A fucoidan derived from marine brown algae has great potential in biomedical filed. Herein, the fucoidan was successfully isolated and purified by using chitosan microspheres, resulting in the sulfate fucoidan (CF) with degree of sulfation (DS) of 0.94. CF was identified to be highly branched, consisting of fucose (77.4%) and galactose (13.9%), etc., supported by the results of GCMS and light scattering with the structure-sensitive parameter of 0.98 in 0.15 M aqueous NaNO3. The individual CF and its desulfated derivative chains adopted sphere-like conformation in water, observed by atomic force microscopy. CF exhibited higher antiangiogenesis than the desulfated one and strong antileukemia activities through inhibiting cell proliferation and inducing cell apoptosis via cell cycle arrest at G1 phase in vitro. This work provided important information that ester sulfate groups of polysaccharide played an important role in the enhancing of bioactivities of fucoidan, and put forward to a potential drug to treat acute myelocytic leukemia (AML) and tumors.

Abstract
Fucus vesiculosus L., known as bladderwrack, belongs to the brown seaweeds, which are widely distributed throughout northern Russia, Atlantic shores of Europe, the Baltic Sea, Greenland, the Azores, the Canary Islands, and shores of the Pacific Ocean. Fucoidan is a major fucose-rich sulfated polysaccharide found in Fucus (F.) vesiculosus. The pharmacokinetic profiling of active compounds is essential for drug development and approval. The aim of the study was to evaluate the pharmacokinetics and tissue distribution of fucoidan in rats after a single-dose oral administration. Fucoidan was isolated from F. vesiculosus. The method of measuring anti-activated factor X (anti-Xa) activity by amidolytic assay was used to analyze the plasma and tissue concentrations of fucoidan. The tissue distribution of fucoidan after intragastric administration to the rats was characterized, and it exhibited considerable heterogeneity. Fucoidan preferentially accumulates in the kidneys (AUC0–t = 10.74 µg·h/g; Cmax = 1.23 µg/g after 5 h), spleen (AUC0–t = 6.89 µg·h/g; Cmax = 0.78 µg/g after 3 h), and liver (AUC0–t = 3.26 µg·h/g; Cmax = 0.53 µg/g after 2 h) and shows a relatively long absorption time and extended circulation in the blood, with a mean residence time (MRT) = 6.79 h. The outcome of this study provides additional scientific data for traditional use of fucoidan-containing plants and offers tangible support for the continued development of new effective pharmaceuticals using fucoidan.
