Alternariol is a mycotoxin, a toxic secondary fungal metabolite, produced by Alternaria molds. It is cytotoxic, fetotoxic, teratogenic, mutagenic, and genotoxic. It induces cytochrome P450 1A1 expression and apoptosis in mouse hepatoma cells (20-40 μM). Alternariol, whose synthesis is inhibited by light, naturally occurs on fruits, vegetables, and cereals, such as apples, tomatoes, and wheat.
