Biological Activity of Plantagoside

Description

1. Plantagoside is a potent inhibitor of the Maillard reaction, it also can inhibit the formation of advanced glycation end products in proteins in physiological conditions and inhibit protein cross-linking glycation. 2. Plantagoside has potential therapeutic applications in the prevention of diabetic complications. 3. Plantagoside is a specific non-competitive inhibitor for jack bean alpha-mannosidase (IC50 at 5 microM). 4. Plantagoside suppresses antibody response to sheep red blood cells and concanavalin A induced lymphocyte proliferation which was measured by [3H]thymidine incorporation.

Potent protein glycation inhibition of plantagoside in Plantago major seeds.[Pubmed:24895551]

Biomed Res Int. 2014;2014:208539.

Plantagoside (5,7,4',5'-tetrahydroxyflavanone-3'-O-glucoside) and its aglycone (5,7,3',4',5'-pentahydroxyflavanone), isolated from a 50% ethanol extract of Plantago major seeds (Plantaginaceae), were established to be potent inhibitors of the Maillard reaction. These compounds also inhibited the formation of advanced glycation end products in proteins in physiological conditions and inhibited protein cross-linking glycation. These results indicate that P. major seeds have potential therapeutic applications in the prevention of diabetic complications.

Plantagoside, a novel alpha-mannosidase inhibitor isolated from the seeds of Plantago asiatica, suppresses immune response.[Pubmed:2610694]

Biochem Biophys Res Commun. 1989 Dec 29;165(3):1292-8.

A hot-water extract from the seed of Plantago asiatica showed a potent inhibitory activity against jack bean alpha-mannosidase, and a flavanone glucoside, Plantagoside, was isolated as the inhibitor. Plantagoside was a specific inhibitor for jack bean alpha-mannosidase (IC50 at 5 microM) and appeared to be a non-competitive inhibitor of the enzyme. Whereas, negligible or weak inhibitory activities were observed for beta-mannosidase, beta-glucosidase, and sialidase tested. Plantagoside also inhibited alpha-mannosidase activities in mouse liver lysosomal and microsomal fractions, and the enzyme inhibitory activity in microsomal fraction was enhanced in the presence of glucosidase inhibitor, castanospermine. Plantagoside suppressed antibody response to sheep red blood cells and concanavalin A induced lymphocyte proliferation which was measured by [3H]thymidine incorporation.
