Concomitant Effect of Quercetin- and Magnesium-Doped Calcium Silicate on the Osteogenic and Antibacterial Activity of Scaffolds for Bone Regeneration

open access: yesAntibiotics, 2021
Quercetin is a bioflavonoid which has a broad spectrum of biological activity. Due to its lower chemical stability, it is usually encapsulated, or a metal–quercetin complex is formed to enhance its biological activity at a lower concentration.

Quercetin and Cancer Chemoprevention [PDF]

open access: yesEvidence-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.
