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).

Actions biochimiques/physiologiques

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.

Notes préparatoires

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

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

The syntheses of isoroquefortine C and a related heterocycle were achieved by implementation of both intra- and intermolecular vinyl amidation reactions. These accomplishments represent a significant advance in the use of these strategies in the generation of complex molecules.
