Fumonisin B1 is a mycotoxin found in the fungus Fusarium moniliforme. This toxin can also be obtained from corn infected with the same fungus. Fumonisin B1 shares similarities with sphingosine and okadaic acid (OA).

Application: Fumonisin B1 from Fusarium moniliforme has been used: as a standard in the analysis of mycotoxins in caecal content obtained from adult pigs, in the study of the effect of fumonisin B1 on the metabolism of prion protein (PrP) isoforms and the synthesis of scrapie prion protein PrPSc, and in the study of the toxic effects of fumonisin B1 on explants obtained from pig jejunum.
Biochem Physiol Actions: Fumonisin B1 is a fungal metabolite that acts as a hepatocarcinogen and causes hepatotoxicity in rats. In horses, Fumonisin B1 causes leukoencephalitis, and in pigs, it causes pulmonary edema syndrome. In China and southern parts of Africa, Fumonisin B1 is linked with high incidence of esophageal cancer in humans. Fumonisin B1 acts as an inhibitor of sphingosine N-acyltransferase enzyme.
