Ochratoxin B

Ochratoxin B is an orally active secondary metabolite of Aspergillus ochraceus and non-chlorinated analog of the mycotoxin Ochratoxin A. Ochratoxin B reduces the toxic effects of Ochratoxin A. Ochratoxin B inhibits cell division. Ochratoxin B causes craniofacial malformations in Xenopus laevis embryos[1][2][3][4][5][6].
