Sulforaphane is an isothiocyanate found in cruciferous vegetables such as broccoli. It has anti-cancer activity and targets multiple pathways in cancer development. It induces chemopreventative enzymes via Keap1-Nrf2 signaling and ARE-driven gene expression and inhibits class I and II Histone Deacetylase activity. It induces the production of detoxifying enzymes such as quinone reductase and glutathione S-transferase.
