Ochratoxin A ,its cas register number is 5303-47-9. It also can be called Phenylalanine - ochratoxin A ; Ochratoxin alpha ; N-{[(3R)-5-Chloro-8-hydroxy-3-methyl-1-oxo-3,4-dihydro-1H-isochromen-7-yl]carbonyl}-L-phenylalanine and L-phenylalanine, N-[[(3R)-5-chloro-3,4-dihydro-8-hydroxy-3-methyl-1-oxo-1H-2-benzopyran-7-yl]carbonyl]- .It is is one of the most abundant food-contaminating mycotoxins in the world and it's a toxin produced by Aspergillus ochraceus and Penicillium verrucosum. The toxin has been found in the tissues and organs of animals, including human blood and breast milk. Human exposure occurs mainly through consumption of improperly stored food products. toxicity of Ochratoxin A (CAS NO.303-47-9) has large species- and sex-specific differences.It has been shown to be weakly mutagenic, possibly by induction of oxidative DNA damage.
Ochratoxin A (CAS NO.303-47-9) is potentially carcinogenic to humans (Group 2B) and can cause immunosuppression and immunotoxicity in animals.A number of descriptive studies have suggested a correlation between exposure to ochratoxin A and Balkan endemic nephropathy, and have found a correlation between the geographical distribution of Balkan endemic nephropathy and a high incidence of, and mortality from, urothelial urinary tract tumours.
