Description
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-
Uses
An alternaria mycotoxin and genotoxin, found in common edible crops. It inhibits the activity of various DNA-topoisomerases, increasing he rate of DNA strand breaks.
Definition
ChEBI: A benzochromenone that is 6H-benzo[c]chromen-6-one which is substituted by a methyl group at position 1 and by hydroxy groups at positions 3, 7, and 9. It is the most important mycotoxin produced by the black mould Alt rnaria species, which are the most common mycoflora infecting small grain cereals worldwide.
General Description
Alternariol belongs to the dibenzo-pyrones chemical group. It is a mycotoxin present in indoor air, soil and plants.
