Fumonisin B1 is a mycotoxin produced from Fusarium moniliforme. Fumonisin B1 is a potent inhibitor of sphingosine N-acyltransferase (ceramide synthase) and disrupts de novo sphingolipid biosynthesis. Fumonisin B1 is the most abundant and toxic fumonisin[1][2]. IC50 & Target: Sphingosine N-acyltransferase[2] In Vitro: Fumonisin B1 alters the gene expression and signal transduction pathways in monkey kidney cells[3].
Fumonisin B1 increases the initial disruption of sphingolipid metabolism and the accumulation of sphinganine in LLC-PK1 kidney cells, causes DNA damage of apoptotic type in rat astrocytes[3].
