Alternariol

Mycotoxin. Phytotoxin. Shows cytotoxic, teratogenic, mutagenic and genotoxic properties by DNA intercalation. Induces several types of DNA damage, including oxidative DNA damage, single-stranded DNA breaks (SSB) and double-strand, through AOH-induced ROS production and interaction with DNA topoisomerase. Inhibits the activity of topoisomerase IIalpha in mammalian cells. Induces cell growth arrest in G2/M phase. GSK-3beta inhibitor (sub-µM IC50 values). Antiviral activity (herpes simplex). Hepatitis C NS3-4A protease inhibitor. Induces cytochrome P450 1A1 expression and apoptosis in mouse hepatoma cells.
