Indole-3-carbinol

Indole-3-carbinol (CAS No.: 700-06-1) is a naturally occurring indole phytochemical derived from cruciferous vegetables through enzymatic hydrolysis of glucobrassinin, widely studied in cancer biology and chemoprevention research. It functions as a pleiotropic modulator of cellular signaling, acting as an inhibitor of NF-κB and Akt pathways, an agonist of the aryl hydrocarbon receptor (AhR), and an inhibitor of the E3 ubiquitin ligase WWP1, thereby influencing inflammation, cell proliferation, apoptosis, and protein turnover. In biological systems, it can undergo acid-catalyzed condensation to form bioactive derivatives such as 3,3’-diindolylmethane, which further modulate oncogene and tumor suppressor gene expression. Indole-3-carbinol exhibits activity across a range of in vitro models typically at low micromolar concentrations, with effects dependent on cellular context and experimental conditions. It is extensively utilized in mechanistic studies of carcinogenesis, hormone-responsive cancers, and xenobiotic signaling, as well as in animal models exploring dietary chemoprevention strategies. Additionally, it has been investigated in clinical research settings, including studies evaluating its potential role in preventing breast cancer in high-risk populations. The concentrations or dosing regimens employed in experimental systems vary according to study design and intended biological endpoints.
