Quercetin and Cancer Chemoprevention [PDF]
Evidence-Based Complementary and Alternative Medicine, 2011 Several molecules present in the diet, including flavonoids, can inhibit the growth of cancer cells with an ability to act as “chemopreventers”. Their cancer‐preventive effects have been attributed to various mechanisms, including the induction of cell‐cycle arrest and/or apoptosis as well as the antioxidant functions.

The role of quercetin in plants [PDF]
Plant Physiology and Biochemistry, 2021 Flavonoids are a special category of hydroxylated phenolic compounds having an aromatic ring structure. Quercetin is a special subclass of flavonoid. It is a bioactive natural compound built upon the flavon structure nC6(ring A)-C3(ring C)-C6(ring B). Quercetin facilitates several plant physiological processes, such as seed germination, pollen growth ...

Deconjugation Kinetics of Glucuronidated Phase II Flavonoid Metabolites by B-glucuronidase from Neutrophils [PDF]
, 2010 Flavonoids are inactivated by phase II metabolism and occur in the body as glucuronides. Mammalian ß-glucuronidase released from neutrophils at inflammatory sites may be able to deconjugate and thus activate flavonoid glucuronides.
