Description | Squamocin, also known as annonin I, 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. annonin i is found in Annona atemoya, Annona cherimola, Annona emarginata, Annona glabra, Annona neosericea, Annona purpurea, Annona reticulata, Annona squamosa, Asimina triloba, Goniothalamus cardiopetalus, Annona mucosa, Uvaria chamae and Uvaria dulcis. It was first documented in 2020 (PMID: 33235438). Based on a literature review a significant number of articles have been published on Squamocin (PMID: 34119221) (PMID: 33563198) (PMID: 32761515) (PMID: 32536722). |
