Diindolylmethane

**Semantic type:** Organic Chemical|Pharmacologic Substance

**Definition:** A phytonutrient and plant indole found in cruciferous vegetables including broccoli, Brussels sprouts, cabbage, cauliflower and kale, with potential anti-androgenic and antineoplastic activities. As a dimer of indole-3-carbinol, diindolylmethane (DIM) promotes beneficial estrogen metabolism in both sexes by reducing the levels of 16-hydroxy estrogen metabolites and increasing the formation of 2-hydroxy estrogen metabolites, resulting in increased antioxidant activity. Although this agent induces apoptosis in tumor cells in vitro, the exact mechanism by which DIM exhibits its antineoplastic activity in vivo is unknown.
