| Description | ISOABIENOL belongs to the class of organic compounds known as diterpenoids. These are terpene compounds formed by four isoprene units. (1r,2r,4as,8as)-2,5,5,8a-tetramethyl-1-(3-methylidenepent-4-en-1-yl)-hexahydro-1h-naphthalen-2-ol is found in Helichrysum cephaloideum, Pinus nigra, Pinus sylvestris, Sagittaria trifolia, Smallanthus fruticosus and Jungermannia infusca. (1r,2r,4as,8as)-2,5,5,8a-tetramethyl-1-(3-methylidenepent-4-en-1-yl)-hexahydro-1h-naphthalen-2-ol was first documented in 2011 (PMID: 21425694). ISOABIENOL is an extremely weak basic (essentially neutral) compound (based on its pKa) (PMID: 22129092) (PMID: 29304384) (PMID: 21315393). |
