5-Chloro-8-hydroxy-3-methyl-1-oxoisochroman-7-carboxylic acid

(R)-Ochratoxin α is an intermediate in the synthesis of Ochratoxin A (O148490). Ochratoxins are toxic metabolites from Aspergillus ochraceus. Also they are environmental and food contaminants.

ChEBI: Ochratoxin alpha is a member of the class of isocoumarins that is 1-oxo-3,4-dihydro-2-benzopyran-7-carboxylic acid carrying additional methyl, chloro and hydroxy substituents at positions 3, 5 and 8 respectively. A non-toxic metabolite of the mycotoxin ochratoxin A. It has a role as a bacterial xenobiotic metabolite, a human urinary metabolite, a human xenobiotic metabolite and a marine xenobiotic metabolite. It is a member of isochromanes, a member of isocoumarins, an organochlorine compound, a member of phenols and a member of benzoic acids. It is a conjugate acid of an ochratoxin alpha(1-).
