Fucoidan, a biologically active polysaccharide, is an efficient inhibitor of α-amylase and α-glucosidase. Anticoagulant, antitumor, antioxidant and antisteatotic activities[1].
体外研究 (In Vitro)
Fucoidan is a biologically active polysaccharide found in great abundance in brown marine algae[1]. Fucoidan extracted from A. nodosum is a more potent inhibitor of α-glucosidase, with an IC50 ranging from 0.013 to 0.047 mg/mL, than the inhibition by Fucoidan extracted from F. vesiculosus (IC50=0.049 mg/mL). Fucoidan extracted from F. vesiculosus does not inhibit α-amylase activity, while Fucoidan from A. nodosum decreases α-amylase activity by 7-100% at 5 mg/mL depending upon the algae harvest period. Fucoidan from A. nodosum inhibits α-amylase with an IC50 of 0.12-4.64 mg/mL[1]. Fucoidan is a fucose-rich sulfated polysaccharide typically found in the cell wall of marine algae but also recently isolated from terrestrial sources. Fucoidan exhibits an attractive therapeutic potential against a wide array of metabolic diseases associated with oxidative stress[2].

体内研究 (In Vivo)
Fucoidan (single injection of 25 mg/kg/body) does not inhibit tumor cell proliferation, while three-time injections of 10 mg/kg/body weight significantly reduces tumor growth and metastasis[3].
