Metabolite Identification
Common NameBrevianamide Q
DescriptionBrevianamide Q is a diketopiperazine, a class of cyclic dipeptides characterized by a unique structural framework consisting of two amino acids linked by peptide bonds and featuring a diketone moiety. Chemical analysis of metabolites from fungal strains has identified brevianamide Q among other compounds, indicating its presence in various fungal species (PMID:39860162 ). Notably, an enzymatic mechanism study revealed that the enzyme AspE facilitates the hydroxylation of brevianamide Q through a novel stereoinversion process, which involves hydrogen atom abstraction followed by a water nucleophilic attack on the iminium cation intermediate (PMID:36750406 ). This transformation is significant as it highlights the complex biochemical pathways that brevianamide Q participates in, contributing to the diverse metabolic profiles of fungi. Additionally, the compound has been isolated alongside other diketopiperazines and metabolites from marine-derived fungi, suggesting its role in the broader context of fungal secondary metabolism and potential ecological interactions.
