Low Molecular Weight, 4-O-Sulfation, and Sulfation at Meta-Fucose Positively Promote the Activities of Sea Cucumber Fucoidans on Improving Insulin Resistance in HFD-Fed Mice

open access: yesMarine Drugs, 2021
Fucoidans from sea cucumber (SC-FUC) have been proven to alleviate insulin resistance in several species. However, there are few studies that clarify the relationship between their structure and bioactivity.

Are Helicobacter pylori Infection and Fucoidan Consumption Associated with Fucoidan Absorption? [PDF]

open access: yesMarine Drugs, 2020
We examined the associations of Helicobacter pylori and mozuku consumption with fucoidan absorption. Overall, 259 Japanese volunteers consumed 3 g fucoidan, and their urine samples were collected to measure fucoidan values and H. pylori titers before and 3, 6, and 9 h after fucoidan ingestion. Compared to the basal levels (3.7 ± 3.4 ng/mL), the urinary

Using pure Fucoidan and radiolabeled Fucoidan (99mTc-Fucoidan) as a new agent for inflammation diagnosis and therapy

open access: yesFood Hydrocolloids for Health, 2022
Inflammation is a phenomenon responsible for the perturbation of homeostasis in several levels, with many sources, such as infection, injury, and exposure to contaminants. The necessity of new products that are effective in treating inflammation processes as can selectively imaging an inflammation site is a global issue.

Fucoidan: Structure and Bioactivity [PDF]

open access: yesMolecules, 2008
Fucoidan refers to a type of polysaccharide which contains substantial percentages of L-fucose and sulfate ester groups, mainly derived from brown seaweed. For the past decade fucoidan has been extensively studied due to its numerous interesting biological activities. Recently the search for new drugs has raised interest in fucoidans.

Fucoidans: Pro- or antiangiogenic agents? [PDF]

open access: yesGlycobiology, 2014
Sulfated polysaccharides of brown algae (fucoidans) attract great attention due to their high and strongly diversified biological activity. This review summarizes recent data on the structural variability of these polysaccharides and reports their anti- and proangiogenic properties.

Extraction of Fucoidan from Turbinaria decurrens and the Synthesis of Fucoidan-Coated AgNPs for Anticoagulant Application [PDF]

open access: yesACS Omega, 2021
Brown seaweeds usually contain alginate as a major polymer. The second major sulfated polymer in brown seaweeds is fucoidan, which has huge potential in medicinal applications. In this study, the photosynthetic pigments from Turbinaria decurrens were first extracted using chloroform/methanol in the ratio of 1:1 (v/v), followed by fucoidan extraction ...
