Metabolite Identification
Common NameDesmethylsulochrin
DescriptionDesmethylsulochrin is a secondary metabolite belonging to the class of benzophenones. It is produced through the enzymatic cleavage of the anthraquinone questin, facilitated by the atypical cofactor-free dioxygenase GedK, which cleaves the C-10-C-4a bond to yield desmethylsulochrin (PMID:34586791 ). This compound has been detected in various studies utilizing ultra-high performance liquid chromatography coupled with mass spectrometry, where it was identified alongside other metabolites such as mevinolinic acid and butyrolactone I (PMID:26603760 ). Additionally, desmethylsulochrin's formation was confirmed in the cell-free extract of Aspergillus terreus, a known producer of (+)-geodin, where enzyme activity catalyzed the ring cleavage of questin (PMID:3182756 ). The identification of desmethylsulochrin was achieved through high-resolution mass spectroscopy and chemical carrier dilution analysis, further supporting its characterization within the metabolic pathways of certain fungal species (PMID:3182756 ). The biosynthesis of desmethylsulochrin highlights its potential significance in the ecological and biological roles of fungi, particularly in the context of secondary metabolite production.
