Description générale

Alternariol belongs to the dibenzo-pyrones chemical group. It is a mycotoxin present in indoor air, soil and plants.

Application

Alternariol from Alternaria sp. may be used as a calibration standard in reverse phase high-performance liquid chromatography (HPLC) and UV-spectrum analysis. It may also be used to spike wholemeal wheat flour for wet baking studies

Actions biochimiques/physiologiques

Alternaria mycotoxins are generally associated with undried food grains post-harvest. The disease caused by Alternaria mycotoxin results in a discolored halo in fruits and spotting in leaves. Alternariol (AOH) is cytotoxic and fetotoxic to microbes and mammalian cells. AOH displays inhibitory effect on cell proliferation and has estrogenic functionality.

The stability of the Alternaria mycotoxins alternariol, alternariol monomethyl ether, and altenuene upon bread baking was investigated by model experiments using a spiked wholemeal wheat flour matrix. For alternariol and alternariol monomethyl ether, but not for altenuene, degradation products, formed

The mycotoxin alternariol (AOH), a frequent contaminant in fruit and cereal products, is known to induce DNA damage with subsequent cell cycle arrest. Here we elucidated the effects of AOH on stages of cell cycle progression using the RAW 264.7

Altertoxin II (ATX II) is one of the several mycotoxins produced by Alternaria fungi. It has a perylene quinone structure and is highly mutagenic in Ames Salmonella typhimurium, but its mutagenicity in mammalian cells has not been studied before. Here

Alternariol (AOH), a mycotoxin produced by Alternaria sp, is often found as a contaminant in fruit and cereal products. Here we employed the murine macrophage cell line RAW 264.7 to test the hypothesis that AOH causes toxicity as a response
