説明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.
使用Sterigmatocystin is a carcinogenic mycotoxin that is struturally related to Aflatoxin. Sterigmatocystin has been shown to inhibit RNA synthesis in rat liver nuclei.
純化方法It crystallises from amyl acetate, Me2CO or EtOH and sublimes in vacuo. It has UV max at 208, 235, 249 and 329nm (log 4.28, 4.39, 4.44 and 4.12). [UV: Bullock et al. J Chem Soc 4179, 1962, UV, IR: Holker & Mulheirn J Chem Soc, Chem Commun 1576, 1576 1968, Birkinshaw & Hammady Biochem J 65 162 1957.] This mycotoxin induces bone marrow changes in mice [Curry et al. Mutation Res 137 111 1984]. [Beilstein 19/10 V 575.]
定義ChEBI: An organic heteropentacyclic compound whose skeleton comprises a xanthene ring system ortho-fused to a dihydrofuranofuran moiety. The parent of the class of sterigmatocystins.
