Common NameRoquefortine C
DescriptionRoquefortine 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. They cause a neurological disease of cattle known as "staggers syndrome". 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. Roquefortine is a very strong basic compound (based on its pKa). Roquefortine is a potentially toxic compound. Tremorgenic mycotoxins exert their toxic effects by interfering with neurotransmitter release, possibly by causing degeneration of nerve terminals. Roquefortine C also interacts with different forms of the cytochromes. Prostration, seizures, and death can also follow after absorption. 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. To control severe tremors caused by tremorgenic mycotoxins, methocarbamol should be administered. Roquefortine C is found in Penicillium roqueforti and Penicillium solitum. They cause a neurological disease of cattle known as "staggers syndrome", which is characterized by muscle tremors, hyperexcitability, convulsions and ataxia.
