Chemical Taxonomy
Description belongs to the class of organic compounds known as pyrroloindoles. Pyrroloindoles are compounds containing a pyrroloindole moiety, which is a tricyclic heterocycle which consists of a pyrrole ring fused to an indole. Pyrrole is 5-membered ring consisting of four carbon atoms and one nitrogen atom. Indole is a bicyclic compound consisting of a six-membered benzene ring fused to a five-membered nitrogen-containing pyrrole ring.

Toxicity Profile
Route of ExposureOral, dermal, inhalation, and parenteral (contaminated drugs). (9)
Mechanism of ToxicityTremorgenic mycotoxins exert their toxic effects by interfering with neurotransmitter release, possibly by causing degeneration of nerve terminals. They are thought to inhibit gamma-aminobutyric acid (GABA) receptors, both pre- and postsynaptic, as well as inhibit transmitter breakdown at the GABA-T receptors. This would initially increase neurotransmitter levels, potentiating the GABA-induced chloride current, then lead to decreased levels of neurotransmitter in the synapse. Roquefortine C also interacts with different forms of the cytochromes. (4, 6)
MetabolismNot Available
Toxicity ValuesLD50: 15-20 mg/kg (Intraperitoneal, Mouse) (5)
Lethal DoseNot Available
Carcinogenicity (IARC Classification)No indication of carcinogenicity to humans (not listed by IARC).
Uses/SourcesRoquefortine C is a tremorgenic mycotoxin produced primarily by Penicillium roquefortii, but also by other Penicillium species. Penicillium roquefortii is used in the production of Roquefort and similar types of blue cheese, and has also been found growing in corn silage and mixed grains. Penicillium elaborated mycotoxins are well recognized as contaminants of many foods. These toxins, including mycophenolic acid (MPA), roquefortine (ROQ), penicillic acid (PA) and patulin (PAT) are reported to be toxic to several mammalian species. (2, 7)
Minimum Risk LevelNot Available
Health EffectsTremorgenic mycotoxins affect central nervous system activity. They cause a neurological disease of cattle known as "staggers syndrome". In severe cases roquefortine C can cause respiratory tract irritation, which can progress to ARDS/acute lung injury. Irritation or burns of the esophagus or gastrointestinal tract are also possible. Prostration, seizures, and death can also follow after absorption. (1, 5, 6)
SymptomsTremorgenic mycotoxins affect central nervous system activity, inducing neurologic symptoms including mental confusion, paralysis, tremors, seizures, and death. They cause a neurological disease of cattle known as "staggers syndrome", which is characterized by muscle tremors, hyperexcitability, convulsions and ataxia. Roquefortine C may also cause irritation of the eyes, skin, and respiratory tract. (1, 6)
TreatmentTo control severe tremors caused by tremorgenic mycotoxins, methocarbamol should be administered. Generalized seizures may be treated with diazepam followed by methocarbamol or a barbiturate such as pentobarbital sodium. Gastric lavage should be performed and activated charcoal administered to limit further absorption of toxins. (3)
