11(13)-Dehydroivaxillin is a sesquiterpene compound used in biochemical research to study anti-inflammatory pathways, potential cancer-fighting properties, and antimicrobial activity. It shows activity in inhibiting certain pro-inflammatory cytokines, prostaglandins, and signaling pathways involved in inflammation. Preliminary studies have demonstrated cytotoxic effects on specific tumor cell lines in vitro and antimicrobial effects against certain microbes, particularly pathogenic fungi. It is investigated for its role in modulating immune responses and as a lead compound in developing novel therapeutics for inflammatory diseases (e.g., rheumatoid arthritis, dermatitis), oncology, and new antimicrobials. Not used in commercial or clinical applications at this stage.
