More than 4, varieties of flavonoids have been identified. All of them are phenyl-benzopyrones of low molecular weight with a basic structure formed by two benzene rings united through a heterocyclic pyrane or pyrone. Besides their relevance in plants, flavonoids are important for human health. Their antioxidant capacity confers a therapeutic potential in cardiovascular diseases, gastric or duodenal ulcers, cancer or hepatic pathologies. Also important are their antiviral and anti-allergic actions, as well as their anti-thrombotic and anti-inflammatory properties. Prostaglandins and nitric oxide biosynthesis is involved in inflammation, and isoforms of inducible nitric oxide synthase iNOS and of cyclooxygenase COX-2 are responsible for the production of a great amount of these mediators. It has been demonstrated that flavonoids are able to inhibit both enzymes, as well as other mediators of the inflammatory process such as reactive C protein or adhesion molecules. Modulation of the cascade of molecular events leading to the overexpression of those mediators include inhibition of transcription factors such as nuclear factor kappa B and AP-1, through the inhibition of protein kinases involved in signal transduction.

Thus, it has been reported that quercetin does not reduce NF-kappaB activation in the renal cortex of rats with established chronic glomerular disease,42 and that while diverse flavonoids downregulate iNOS expression in RAW Effects on adhesion molecules Endothelial dysfunction has an enormous importance in the inflammatory processes, and involves changes in the expression of endothelial adhesion molecules, such as ICAM-1, VCAM-1 and E-selectin, among others,58,59 able to trigger the inflammatory process by stimulating the migration and adhesion of leukocytes and originating tissue damage.


Flavonoids, in addition to his capacity to inhibit in vitro lipoprotein oxidation and to their antithrombotic effects, seem to also exert their beneficial action in cardiovascular diseases by modulating monocyte adhesion during the atherosclerotic inflammatory. Organisms have developed a variety of antioxidant defense systems as protection from ROS.

Aglycons and glucosides are absorbed in the small intestine, but they are transformed quickly into methylated, sulfated or glucuronic acidconjugated derivative.

Bacteria of the colon play an important role in the metabolism and absorption of flavonoids and the derivatives do not necessarily present the same biological activity than the original compounds.

Whatever it is the case, the data nowadays available make clear the potential utility that have dietary flavonoids or new flavonoid-based agents for the possible treatment of inflammatory diseases. References 1.
