    Abstract

    Dipeptidyl-peptidase-4 is a multifunctional ectoenzyme, which is implicated with hyperglycemic pathophysiology. Therefore, dipeptidyl-peptidase-4 inhibitors could be used as an attractive therapeutic strategy in blood-glucose homeostasis to attenuate the pathophysiologies of diabetes. A sulfated galactofucan characterized as [!1)-O-4-sulfonato-a-fucopyranosyl-(2!1)-O-2-sulfonatoa-fucopyranose-(3!] along with a branch of [!1)-6-O-methylb-galactopyranosyl-(4!] unit at the C-4 position of O-2-sulfonatoa-fucopyranose, isolated from the seaweed Padina tetrastromatica, exhibited prospective attenuation property against dipeptidylpeptidase-4 (IC50 0.25 mg mL1). The studied sulfated galactofucan exhibited potential inhibitory properties against carbolytic enzymes a-amylase (IC50 0.98 mg mL1) and a-glucosidase (IC500.87 mg mL1) in comparison with the standard antidiabetic agent acarbose, along with radical scavenging activities. The seaweed-originated galactofucan could be developed as a promising natural therapeutic lead against hyperglycemic disorder.
