Description

Fumonisin B2 is from Fusarium moniliforme Fumonisin B2 is a fumonisin mycotoxin produced by the fungi Fusarium verticillioides and Fusarium moniliforme. It is a structural analog of fumonisin B1. Fumonisin B2 is more cytotoxic than fumonisin B1. Fumonisin B2 inhibits sphingosine acyltransferase. Fumonisin B2 belongs to the family of Monoterpenes. These are compounds contaning a chain of two isoprene units.

Chemical Taxonomy

Description

belongs to the class of organic compounds known as fumonisins. These are diesters of propane-1,2,3-tricarboxylic acid (TCA) and similar long-chain aminopolyol backbones (for FB1: 2S-amino-12S,16R-dimethyl-3S,5R,10R,14S,15R-pentahydroxyeicosane). Structurally, fumonisins resemble the sphingoid bases sphinganine (SA) and sphingosine (SO) to which TCA groups have been added at the C-14 and C-15 positions.

Toxicity Profile

Route of Exposure

Oral, dermal, inhalation, and parenteral (contaminated drugs). (4)

Mechanism of Toxicity

Fumonisins are similar in structure to the long-chain base backbones of sphingolipids, allowing it to inhibit of the biosynthesis of sphingosine and more complex sphingolipids by inhibiting the enzyme ceramide synthase. This causes the accumulation of sphinganine, sphingosine, and possibly also sphingosine 1-phosphate in cells and tissues, leading to apoptosis. (1, 6, 2, 3)

Metabolism

Toxicity Values

Not Available

Lethal Dose

Not Available

Carcinogenicity (IARC Classification)

2B, possibly carcinogenic to humans. (5)

Uses/Sources

Fumonisin B2 is a fumonisin mycotoxin produced by the fungi Fusarium verticillioides and Fusarium moniliforme. Fumonisin B2 and other fumonisins frequently contaminate maize and other crops. (7)

Minimum Risk Level

Not Available

Health Effects

Fumonisins are hepatotoxic and nephrotoxic, causing increased apoptosis followed by regenerative cell proliferation. Leukopenia, sepsis, bone marrow suppression, hemosiderosis, and multiple hemorrhages have all been reported. Contact with skin and eyes can cause coagulation necrosis. Angina, tachycardia, and hypotension may occur. Animals studies have also shown disturbed sphingolipid metabolism and cardiovascular dysfunction. (1, 6)

Symptoms

Anorexia, vomiting and diarrhea, which may be bloody, may occur. Shortness of breath, pulmonary hemorrhage, headache, and vertigo are other symptoms. (1)

Treatment

There are no known antidotes to trichothecene mycotoxins. Treatments are directed at supporting hemopoietic abnormalities, gastrointestinal damage, and skin damage. Condiser activated charcoal if absorbed orally. Proceed with decontamination of the exposed region in case of eye or dermal contact. Administer oxygen and assist ventilation as required. Treat bronchospasm with inhaled beta2 agonist and oral or parenteral corticosteroids. (1)
