Ascofuranone

Ascofuranone is a secondary metabolite originally isolated from fungal cultures and characterized as an isoprenoid antibiotic. It strongly inhibits trypanosome alternative oxidase (TAO), a mitochondrial enzyme essential for the respiratory metabolism of Trypanosoma species. By blocking TAO, ascofuranone disrupts parasite energy production and demonstrates significant trypanocidal activity in animal models. In addition to its antiparasitic activity, ascofuranone has been reported to suppress epithelial-mesenchymal transition (EMT) and cell migration in cancer models via modulation of ERK, AKT/mTOR, and c-Myc signaling pathways. These properties position ascofuranone as a promising lead compound for antiparasitic and anticancer drug development.
