Anti-inflammatory activity, catechols

The numerous health related properties of flavonoids, widely described in epidemiological studies, are mainly based on their antioxidant activities. These properties have been found to include anti-inflammatory and antiviral activities, effects on capillary fragility, inhibition of human platelet aggregation and anticancer activity. The antioxidant capacity of any flavonoid will be determined by a combination of the catechol structure in the B-ring, the 2,3-double bond in conjunction with a 4-oxo function, and the presence of both hydroxyl groups in positions 3 and 5. Due to their...
