DescriptionEnniatins are mycotoxins that appear in nature as a mixture of cyclohexadepsipeptides produced by bacteria, fungi, and plants. They may be found in contaminated cereal crops. Enniatins have various biological activities and can act as enzyme inhibitors, antifungal and antibacterial agents, and immunomodulatory substances. (5, 1)

Chemical Taxonomy
Description belongs to the class of organic compounds known as cyclic depsipeptides. These are natural or synthetic compounds having sequences of amino and hydroxy carboxylic acid residues (usually α-amino and α-hydroxy acids) connected in a ring. The residues are commonly but not necessarily regularly alternating.

Toxicity Profile
Route of ExposureOral, dermal, inhalation, and parenteral (contaminated drugs). (4)
Mechanism of ToxicityEnniatins are toxic due to their ability to act as ionophores, changing ion transport across membranes and disrupting the ionic selectivity of cell walls. In the membrane, enniatins form a dimeric structure and are able to transport monovalent ions (especially K+, Mg2+,Ca2+ and Na+) across the membranes. This effect is particularly harmful in mitochondrial membranes, resulting in the uncoupling of oxidative phosphorylation. They are also know to inhibit several enzymes, including acyl coenzyme A:cholesterol acyltransferase and cyclic nucleotide phosphodiesterase. Enniatins are cytotoxic and can cause DNA fragmentation, induce apoptosis, and disrupt the ERK signalling pathway. They can also inhibit the activity of membrane-located ATP-binding cassette (ABC) transporters, multidrug pumps which affect the bioavailability of xenobiotics and pharmaceuticals. (1, 2, 3)
