赭曲毒素B（一种二氢异香豆素衍生物）是被广泛研究的赭曲毒素A的非氯化类似物。该化合物是由与食物变质相关的相同种类的曲霉和青霉共同生产的。当在大鼠中施用赭曲霉毒素B时，尿液中发现了两种荧光代谢物，即4-羟基赭曲霉毒素B和曲毒素B。已显示曲毒素B应用于非洲爪蟾会诱发面部异常。该化合物在人源细胞中未显示出遗传毒性活性。赭曲毒素B已被证明可减少由赭曲毒素A引起的毒性作用。 Product Describtion: Ochratoxin B (A dihydroisocoumarin derivative) is A widely studied non-chlorinated analogue of O-trotoxin A. The compound is produced by the same species of Aspergillus and Penicillium that are associated with food spoilage. When CH aspergillus B was administered to rats, two fluorescent metabolites were found in the urine, namely, 4-hydroxyl Ra aspergillus B and trexoxin B. Tratoxin B has been shown to induce facial abnormalities in Xenopus laevis. The compound showed no genotoxic activity in human cells. Ch trotoxin B has been shown to reduce the toxic effects caused by CH trotoxin A.
