Sterigmatocystin

Sterigmatocystin is a mycotoxin that has been found in Aspergillus. It is lethal to rats (LD50 = 60 mg/kg) and chick embryos (LD50s = 5-7 µg/embryo). Sterigmatocystin (100 and 1,000 ppb in drinking water) induces gastritis, as well as intestinal polyp formation and metaplasia in aged Mongolian gerbils. It induces formation of lung and liver adenomas and malignant lymphomas in newborn mice.Formal Name: (3aR,12cS)-3a,12c-dihydro-8-hydroxy-6-methoxy-7H-furo[3',2':4,5]furo[2,3-c]xanthen-7-one.
