Fumonisin B2
Based on 1 Customer Validation
Fumonisin B2 is a selective ceramide synthase inhibitor and carcinogenic mycotoxin with toxicity comparable to that of Fumonisin B1 (HY-N6719). Fumonisin B2 inhibits de novo sphingolipid biosynthesis by blocking the amide bond formation between fatty acids and dihydrosphingosine, which leads to a massive intracellular accumulation of free dihydrosphingosine, altered sphingosine levels, subsequent inhibition of cell proliferation, and induction of cell death. Fumonisin B2 is used to investigate the pathogenesis of diseases associated with Fusarium verticillioides contamination, including equine leukoencephalomalacia, porcine pulmonary edema syndrome, human esophageal cancer, and rat hepatocellular carcinoma.

Biological Activity
Sphingosine N-acyltransferase[2]
Fumonisin B2 (10-35 μM; 3-5 days) exerts a proliferation-inhibiting effect on LLC-PK1 cells; the cells first exhibit fibroblast-like morphological changes, and this effect is reversible after drug removal[1].
Fumonisin B2 (5 μM; 1 h) binds to lactic acid bacteria (e.g., Lactobacillus paraplantarum CNRZ 1885, Streptococcus thermophilus RAR1) under acidic conditions, with a stronger binding capacity than Fumonisin B1[2].
Fumonisin B2 (7 days of culture; 50 minutes of extraction) is exclusively produced by Aspergillus niger strains NRRL 3122, NRRL 328, NRRL 3 and NRRL 326, with the highest yield observed on Czapek yeast autolysate agar supplemented with 5% NaCl, and no toxin production is detected on malt extract agar[3].

Animal Model:42-48-day-old male Sprague-Dawley rats ( 149.1±0.8 g to 181.9±1.3 g)[4]
-
Dosage:0.75 mg/kg
-
Administration:Intraperitoneal injection; once daily; for 2, 4, or 6 days.
-
Result:Showed a significant decrease in body weight only on the last 2 days of the 6-day study.
Significantly reduced the food consumption on the second to last day of the 4-day study and the last 2 days of the 6-day study.
Significantly elevated the serum biochemical parameters including alanine aminotransferase (ALT), creatinine, total protein, IgM, calcium, and magnesium on day 6.
Increased the number of vacuolated bone marrow cells consistently at all time points.
Resulted histopathological changes included single cell necrosis in the liver and kidneys, cytoplasmic vacuolation in the adrenal cortex, and mild to moderate lymphocytolysis in the thymic cortex after 4 and 6 days of exposure.
In the liver, significantly upregulated mRNA expression of p21 and cyclin E genes, while significantly downregulated mRNA expression of p27 and cyclin D1 genes.
There were no significant changes in the protein levels of p27, cyclin E, cyclin D1, and proliferating cell nuclear antigen (PCNA) compared to the control group.
