sterigmatocystyna

Sterigmatocystin is a mycotoxin produced by certain species of fungi, notably *Aspergillus versicolor*. It is a structurally related compound to aflatoxins, another group of potent mycotoxins. Sterigmatocystin is a difuranocoumarin, meaning it contains two furan rings fused to a coumarin core.

The production of sterigmatocystin by fungi is often associated with stored grains, fruits, and other agricultural products, particularly under conditions of high humidity and temperature. While not as acutely toxic as aflatoxins, sterigmatocystin is a significant concern due to its known mutagenic and carcinogenic properties. Studies have indicated that it can induce DNA damage and is considered a potential carcinogen in animal models, primarily affecting the liver.

The presence of sterigmatocystin in food and feed can pose a risk to human and animal health. Monitoring and control strategies are important in agricultural settings to minimize the growth of toxigenic fungi and prevent contamination. Research continues to explore the precise mechanisms of its toxicity and to develop effective methods for its detection and detoxification.
