Common NameBerkeleydione
DescriptionBerkeleydione is a meroterpenoid, a class of compounds that combines features of terpenes and polyketides. Its chemical structure is characterized by a complex arrangement, specifically identified as (5aS,7R,9S,11R,11aS)-methyl 9-hydroxy-1,1,5,7,9,11a-hexa-methyl-14-methyl-idene-3,8,10-trioxo-1,3,4,5a,6,7,8,9,10,11,11a,12-dodeca-hydro-7,11-methano-cycloocta-[4,5]cyclo-hepta-[1,2-c]pyran-11-carboxyl-ate, with the molecular formula C26H32O7 (PMID:26029438 ). Berkeleydione is synthesized through a biosynthetic gene cluster in the fungus Penicillium rubrum, where it acts as a key intermediate in the formation of various meroterpenoids (PMID:27602587 ). The compound has been isolated alongside other metabolites, including berkeleytrione, and its structure has been elucidated using mass spectrometry and NMR techniques (PMID:17970594 ). Notably, berkeleydione has demonstrated bioactivity by inhibiting matrix metalloproteinase-3 and caspase-1, as well as showing potential antitumor activity against non-small-cell lung cancer cell lines (PMID:15012097 ). Additionally, its biosynthetic pathway involves unique transformations, such as a retro-Claisen migration of methyl carbonate (PMID:18237180 ).
