Metabolite Identification
Common NameAlternariol-9-methyl ether
DescriptionAlternariol methyl ether, also known as AME, belongs to the class of organic compounds known as coumarins and derivatives. These are polycyclic aromatic compounds containing a 1-benzopyran moiety with a ketone group at the C2 carbon atom (1-benzopyran-2-one). Alternariol methyl ether is metabolized by microsomes in the liver, preferentially at aromatic positions. It is also demethylated to alternariol. Alternariol methyl ether is an altertoxin, which is a mycotoxin of Alternaria fungi. It has demonstrated DNA-damaging activities such as single-strand and double-strand DNA breaks, DNA-intercalating, and DNA cross-linking, as well as induction of DNA repair synthesis and inhibition of DNA replication. Alternariol methyl ether has been shown to have genotoxic and mutagenic properties. Alternariol methyl ether is an extremely weak basic (essentially neutral) compound (based on its pKa). Alternariol methyl ether is a potentially toxic compound. Studies have shown altertoxins to be toxic, genotoxic, mutagenic, and carcinogenic. These effects are thought to be at least partially due to its ability to bind to the DNA minor groove with high affinity, which inhibits the activity of DNA-acting enzymes such as topoisomerase. The products of aromatic hydroxylation are either catechols or hydroquinones, which may form reactive semiquinones and quinones or undergo redox cycling.
