Penitrem A
Chemical compound
Penitrem A (tremortin) is an indole-diterpenoid mycotoxin produced by certain species of Aspergillus, Claviceps, and Penicillium, which can be found growing on various plant species such as ryegrass.[1] Penitrem A is one of many secondary metabolites following the synthesis of paxilline in Penicillium crostosum.[2] Penitrem A poisoning in humans and animals usually occurs through the consumption of contaminated foods by mycotoxin-producing species, which is then distributed through the body by the bloodstream.[2] It bypasses the blood-brain barrier to exert its toxicological effects on the central nervous system.[2] In humans, penitrem A poisoning has been associated with severe tremors, hyperthermia, nausea/vomiting, diplopia, and bloody diarrhea.[2] In animals, symptoms of penitrem A poisoning has been associated with symptoms ranging from tremors, seizures, and hyperthermia to ataxia and nystagmus.[2]
Roquefortine C has been commonly detected in documented cases of penitrem A poisoning, making it a possible biomarker for diagnoses.[3]
