Metabolite Identification
Common Name8-Hydroxyhyperforin 8,1-hemiacetal
DescriptionSquamolinone belongs to the class of organic compounds known as annonaceous acetogenins. These are waxy derivatives of fatty acids (usually C32 or C34), containing a terminal carboxylic acid combined with a 2-propanol unit at the C-2 position to form a methyl- substituted alpha,beta-unsaturated-gamma-lactone. One of their interesting structural features is a single, adjacent, or nonadjacent tetrahydrofuran (THF) or tetrahydropyran (THP) system with one or two flanking hydroxyl group(s) at the center of a long hydrocarbon chain. Squamolinone is an extremely weak basic (essentially neutral) compound (based on its pKa).
