Common Namepreaustinoid A
DescriptionPreaustinoid A is a meroterpene, a chemical class that combines both terpenoid and non-terpenoid components, characterized by its complex tetracyclic structure featuring a bicyclo[3.3.1]nonane core. The systematic name for preaustinoid A is methyl 15-hydr-oxy-2,6,6,10,13,15-hexa-methyl-17-methyl-ene-7,14,16-trioxotetra-cyclo-[11.3.1.0(2,11).0(5,10)]hepta-decane-1-car-box-yl-ate, with a molecular formula of C(26)H(36)O(6). Its synthesis involves intricate pathways, including epoxypolyene cyclization, as demonstrated in the total synthesis of berkeleyone A and preaustinoid A (PMID:39445483 ). In biological contexts, preaustinoid A serves as a substrate for fungal Fe(II)/αKG oxygenases, such as AusE from Aspergillus nidulans and PrhA from Penicillium brasilianum, which catalyze divergent rearrangement reactions to produce compounds like austinol and paraherquonin (PMID:29317628 ). Additionally, it has been isolated alongside other metabolites from various fungi, highlighting its role in the biosynthetic pathways of bioactive compounds (PMID:28648623 , PMID:21581839 ).
