What is alternariol monomethyl ether?
The Uses of alternariol monomethyl ether
Alternariol Monomethyl Ether is a mycotoxins found in subsistence farmed maize. Also, it is a natural mycotoxin isolated from the fermentation broth of Trichoderma sp. Jing-8 with phytotoxic, antibacterial and antioxidant activities. Also, it is derived from 3,5-Dimethoxyiodobenzene (D460640), which is an intermediate for the synthesis of glucuronide conjugates of trans-Resveratrol.
Definition
ChEBI: Djalonensone is a benzochromenone that is alternariol in which the hydroxy group at position 9 has been converted into the corresponding methyl ether. A natural product found in Chaetomium globosum as well as being one of the two most important compounds belonging to the group of Altenaria mycotoxins. It has a role as an antifungal agent, a fungal metabolite and a mycotoxin. It is a benzochromenone and an aromatic ether. It is functionally related to an alternariol.
General Description
Alternariol-9-methyl ether (AME) is a mycotoxin produced by fungus Alternaria and a major plant pathogen found in a wide variety of fruits and cereals products.
