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].

While three injections of 10 mg/kg/body weight of fumoidan dramatically diminish tumor development and metastasis, a single injection of 25 mg/kg/body does not prevent the proliferation of tumor cells[3].

| Animal Protocol |
Animal/Disease Models: Mice[3]
Doses: 10-400 mg/kg Route of Administration: intraperitoneal (ip) injection; followed by total-body irradiation Experimental Results: The mice injected with 100 mg/kg demonstrated the best survival rate at 30 days post-irradiation. |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation:：Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
