Roquefortine C, a cyclopeptide derived from the diketopiperazine cyclo(Trp-dehydroHis), is a secondary metabolite produced by several Penicillium species, especially by Penicillium roqueforti, which is used as starter culture for blue cheese production. Although roquefortine C is frequently detected in the products, it obviously has an insignificant toxicity to humans after ingestion. However, intoxications in dogs and cattle have been reported. Its bacteriostatic activities against Gram-positive bacteria lead to Roquefortine C potential use in antibiotics, but its development as a drug has been stopped due to its neurotoxic effects in mice. Roquefortine C activates P-gp and inhibits P450-3A and other haemoproteins. Roquefortine C can serve as a sensitive biomarker for penitrem A intoxication.

In Vitro Use Guide

The MIC of roquefortine C for gram-positive organisms were about 80 ug/mL cells on the average. The sensitive bacterium Corynebacterium flaccumfaciens was chosen for characterizing the antimicrobial action of the mycotoxin. Addition of low roquefortine C concentrations at the beginning of bacterial growth resulted in prolongation of both the lag and logarithmic phases. High toxin concentrations (100 ug/mL cells) added to growing cells caused prolongation of logarithmic growth and decreased maximum cell density.
