In vitro and in vivo hypoglycemic effects of brown algal fucoidans
Abstract
The inhibition of α-glucosidase is an effective therapeutic approach for type 2 diabetes mellitus that involves decreasing postprandial hyperglycemia. In the present study, the α-glucosidase and α-amylase inhibitory effects of 11 fucoidans extracted from different brown seaweeds were evaluated. Although no significant α-amylase inhibition was observed, fucoidan from Fucus vesiculosus (FvF) showed the highest α-glucosidase inhibitory activity, with an IC50 value of 67.9 μg/mL. In addition, FvF at a concentration of 200 μg/mL displayed very mild cytotoxicity to IEC-6 cells as indicated by the MTT assay. An in vivo study indicated that FvF decreased the fasting blood glucose and hemoglobin A1c (HbA1c) levels of db/db mice, with minimal effect on their weight. Therefore, our present in vitro and in vivo studies demonstrated that FvF could be a promising α-glucosidase inhibitor for the treatment of type 2 diabetes mellitus.

“Algae are considered as a good source of dietary fibers because of the presence of non-digestible polysaccharides in the algal cell wall (Figure 3) [11]. It has been shown that they possess activities, like antioxidant [12], hypoglycemic [13], antiviral [14,15], antitumor [16], and anti-inflammatory due to the presence of fucoidan and laminarin [17].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
