Application
Roquefortine C has been used as a standard for the quantification of roquefortine C by high-performance liquid chromatography (HPLC). It has also been used as a standard for the quantification of roquefortine C by liquid chromatography-mass spectrometry (LC−MS/MS).
Biochem/physiol Actions
Roquefortine C is a paralytic neurotoxin of a dioxopiperazine structure produced by a diverse range of fungi, most notably Penicillium species.
Roquefortine C is a paralytic neurotoxin of a dioxopiperazine structure produced by a diverse range of fungi, most notably Penicillium species. It has been found in blue cheese and in many other food products due to natural occurrence and contamination. Roquefortine C was found to be active on a wide range of organisms. It inhibits the growth of Gram-positive bacteria, and cockerels treated with roquefortine lost their righting reflex and died within 8-12 hours. Mice injected with roquefortine C experienced neurotoxic properties. Roquefortine C was also reported to inhibit cytochrome P450 as well as tubulin polymerization.
Preparation Note
Soluble in methanol (10 mg/mL), DMSO (10 mg/mL), ethyl acetate (1 mg/mL) and chloroform (1 mg/mL). DMSO solution at 10 mg/mL is stable for 3 months at −20 °C.

We have studied the role of the pga1 gene of Penicillium chrysogenum, encoding the alpha subunit of a heterotrimeric G protein, in secondary metabolite production. The dominant activating pga1(G42R) mutation caused an increase in the production of the three secondary

Two dogs developed alarming tremorgenic nervous stimulation shortly after ingesting discarded rice that had been forgotten in a refrigerator for an undetermined period and that was covered with a grey-green mould. Both dogs exhibited vomition followed by slight salivation, tremors

In vitro and in vivo studies have shown that building-associated Penicillium spores and spore extracts can induce significant inflammatory responses in lung cells and animal models of lung disease. However, because spores and spore extracts comprise mixtures of bioactive constituents

Heterotrimeric G protein signaling regulates many processes in fungi, such as development, pathogenicity, and secondary metabolite biosynthesis. For example, the Galpha subunit Pga1 from Penicillium chrysogenum regulates conidiation and secondary metabolite production in this fungus. The dominant activating allele, pga1G42R
