Chemical structure of verruculogen

Verruculogen is a mycotoxin produced by certain species of fungi, particularly those belonging to the genus Aspergillus. It is a member of the indole alkaloid family and is known for its neurotoxic effects.

Chemical Structure and Properties

Verruculogen is characterized by a complex chemical structure that includes an indole moiety. The molecular formula of verruculogen is C27H33N3O6, and it has a molecular weight of 495.57 g/mol. The structure of verruculogen includes several epoxide groups, which are believed to contribute to its biological activity.

Biosynthesis

The biosynthesis of verruculogen involves a series of enzymatic reactions that occur within the fungal organism. It is synthesized from tryptophan, a common precursor for many indole alkaloids. The biosynthetic pathway includes the formation of several intermediate compounds before the final product, verruculogen, is produced.

Toxicity

Verruculogen is known for its neurotoxic effects, which can lead to tremors and other neurological symptoms in animals. It acts by inhibiting the gamma-aminobutyric acid (GABA) receptor, which is crucial for neurotransmission in the central nervous system. This inhibition can lead to uncontrolled neuronal firing and subsequent neurological symptoms.

Occurrence

Verruculogen is primarily produced by Aspergillus species, including Aspergillus fumigatus and Aspergillus nidulans. These fungi are commonly found in soil and decaying organic matter. They can also contaminate food and feed, posing a risk to human health and animal health.

Detection and Analysis

The detection of verruculogen in food and feed is important for ensuring safety. Analytical methods such as high-performance liquid chromatography (HPLC) and mass spectrometry (MS) are commonly used to identify and quantify verruculogen in samples. These methods provide sensitive and accurate measurements of verruculogen concentrations.
