Ochratoxin A

(2S)-2-{[(3R)-5-chloro-8-hydroxy-3-methyl-1-oxo-3,4-dihydro-1H-2-benzopyran-7-carbonyl]amino}-3-phenylpropanoic acid

C20H18ClNO6 (403.0823)


Ochratoxin A is found in barley. Mycotoxin. Ochratoxin A is produced by Aspergillus melleus, Aspergillus sulphureus and Penicillium viridicatum.Potential contaminant of foodstuffs, especially cereals. Ochratoxin A is found in stored grain products in UK (1997).Ochratoxin A, a toxin produced by Aspergillus ochraceus and Penicillium verrucosum, is one of the most abundant food-contaminating mycotoxins in the world. Human exposure occurs mainly through consumption of improperly stored food products, particularly contaminated grain and pork products, as well as coffee, wine grapes and dried grapes. The toxin has been found in the tissues and organs of animals, including human blood and breast milk. Ochratoxin A toxicity has large species- and sex-specific differences Mycotoxin.

Ochratoxin A

NCGC00162403-05_C20H18ClNO6_L-Phenylalanine, N-[[(3R)-5-chloro-3,4-dihydro-8-hydroxy-3-methyl-1-oxo-1H-2-benzopyran-7-yl]carbonyl]-

C20H18ClNO6 (403.0823)


A phenylalanine derivative resulting from the formal condensation of the amino group of L-phenylalanine with the carboxy group of (3R)-5-chloro-8-hydroxy-3-methyl-1-oxo-3,4-dihydro-1H-2-benzopyran-7-carboxylic acid (ochratoxin alpha). It is among the most widely occurring food-contaminating mycotoxins, produced by Aspergillus ochraceus, Aspergillus carbonarius and Penicillium verrucosum.
