Flavonoïdes et Polyphénols

<p>Applications Isovitexin is known as a flavones, a class of flavonoids. Isovitexin have been studied for their antiradical activities in the process of metabolisms. Isovitexin have also been studied for beneficial effcts against atherosclerosis, osteoporosis and certain cancers.<br>References Cermak, R., et al.: Expert. Opin. Drug. Metab.

<p>Applications A natural phenolic compound. Potent anti-tumor agent having anti-inflammatory and antioxidant properties. Induces apoptosis in cancer cells and inhibits phorbol ester-induced protein kinase C (PKC) activity. Reported to inhibit production of inflammatory cytokines by peripheral blood monocytes and alveolar macrophages. Potent inhibitor of EGFR tyrosine kinase and IκB kinase. Inhibits inducible nitric oxide synthase (iNOS), cycloxygenase and lipoxygenase. Easily penetrates into the cytoplasm of cells, accumulating in membranous structures such as plasma membrane, endoplasmic reticulum and nuclear envelope.Curcumin is currently being examined as a possible therapeutic for the treatment of Alzheimers disease. Neuroprotective. Dyes and metabolites.<br>References Srinivasan, et al.: J. Pharm.

<p>Applications A major component of green coffee the extracts of which promote weight loss in overweight and obese people. Chlorogenic Acid is an important intermediate in lignin biosynthesis. Chlorogenic Acid is an antioxidant and an inhibitor of the tumor promoting activity of phorbol ester. It has protective effect against streptozotocin-nicotinamide generated oxidative stress induced diabetes and may also protect against cardiovascular disease.<br>References Chem. and Eng.

<p>Stability Light Sensitive<br>Applications Minor constituent of wine, correlated with serum lipid reduction and inhibition of platelet aggregation. Resveratrol is a specific inhibitor of COX-1, and it also inhibits the hydroperoxidase activity of COX-1. It has been shown to inhibit events associated with tumor initiation, promotion and progression.<br>References Powell, R.G., et al.: Phytochemistry, 35, 335 (1994), Jeandet, P., et al.: J.

<p>Stability Light Sensitive<br>Applications Bisdemethoxycurcumin is one of the three major forms of curcuminoids found in the rhizomes of turmeric. Bisdemethoxycurcumin displays antioxidant, anti-inflammatory as well as chemotherapeutic activity. Bisdemethoxycurcumin acts as an inhibitor of human pancreatic α-amylase, a target for type-2 diabetes .<br>References Ponnusamy, S. et al.: Food Chem., 135, 2638 (2012); Hung, C.-M. et al.: J. Agric.

<p>Stability Hygroscopic<br>Applications Digallic Acid is an intermolecular ester of Gallic acid (G188900), a phenolic acid with antioxidant activity. Gallic acid was found to protect human cells against oxidative damage and showed cytotoxicity against cancer cells. Gallic Acid and its esters also show antiviral and antifungal activities.<br>References Yen, G. et al.: Food Chem., 79, 307 (2002); Chen, C. et al.: Mol. Nutrit.
