Effects of catechins, resveratrol, silymarin components and some of their conjugates on xanthine oxidase‐catalyzed xanthine and 6‐mercaptopurine oxidation

Journal of the Science of Food and Agriculture, Volume 105, Issue 5, Page 2765-2776, 30 March 2025.
Abstract BACKGROUND Over the past two decades, the global incidence of gout has markedly increased, affecting people worldwide. Considering the side effects of xanthine oxidase (XO) inhibitor drugs (e.g. allopurinol and febuxostat) used in the treatment of hyperuricemia and gout, the potential application of phytochemicals has been widely studied.

Pyruvate Kinase M2 Mediates Apigenin‐Induced Energy Crisis and Apoptosis in Colon Cancer Cells

Food Frontiers, Volume 7, Issue 4, July 2026.
Apigenin, a dietary flavonoid with low toxicity, induces profound bioenergetic collapse in colon cancer cells by downregulating PKM2. This metabolic crisis, characterized by suppressed glycolysis and mitochondrial dysfunction, ultimately triggers robust apoptosis.
