Common Nameatrochrysone
Descriptionatrochrysone is a polyketide, specifically a member of the (pre-)anthraquinone chemical class, widely recognized for its role as a biosynthetic precursor in various natural compounds. Its chemical structure is characterized by a tricyclic framework, which is synthesized through the action of polyketide synthases (PKS). The biosynthetic pathway involves the methylation of atrochrysone to form its 6-O-methyl ether, torosachrysone, by the O-methyltransferase CoOMT1, followed by regioselective homocoupling to phlegmacin, catalyzed by the enzyme CoUPO1 (PMID:38963262 ). Additionally, the enzyme CoPKS1 predominantly produces atrochrysone carboxylic acid, while CoPKS4 exhibits both hepta- and octaketide synthase activities (PMID:36507600 ). This compound has been identified in fungi, particularly in mushrooms of the genus Cortinarius, which are known to produce atrochrysone-derived pigments (PMID:35218274 ). Furthermore, the efficient heterologous production of atrochrysone carboxylic acid-related polyketides has been achieved in Aspergillus oryzae, utilizing enhanced malonyl-CoA supply (PMID:31776294 ). Overall, atrochrysone plays a crucial role in the complex biosynthetic pathways leading to diverse bioactive compounds.
