Isoflavonoids and Epigenetic Modulation: Therapeutic Insights for Cancer Treatment
Chemistry &Biodiversity, Volume 23, Issue 2, February 2026.Venn diagram illustrating the epigenetic roles of three phytochemical groups—flavonoids, isoflavonoids, and pterocarpans. ABSTRACT Isolavonoides represent the second largest subgroup of flavonoids and have an influence on critical molecular pathways and restore cellular homeostasis, through the reprogramming of epigenetic regulatory mechanisms.
