| | (+)-Ledene Usage And Synthesis |
| Description | (+)-Ledene, also called leden or viridiflorene, is an organic compound that belongs to the group of 5, 10-cycloaromadendrane sesquiterpenoids. These compounds are derived from the aromadendrane skeleton through a cyclization reaction between carbon atoms 5 and 10. (+)-Ledene is mainly found in saliva and is considered to have low solubility in water and a relatively neutral nature. In cellular environments, (+)-ledene is predominantly present in the cell membrane (predicted based on logP) and cytoplasm. | | Uses | (+)-Ledene is an essential oil that is synthesized by viridiflorene synthase. It has been studied as an antioxidant, antimicrobial, antibiofilm and to treat various cancers. | | Definition | ChEBI: Viridiflorene is a carbotricyclic sesquiterpene obtained from several natural sources, including Australian Tea Tree oil (Melaleuca alternifolia.) It is a sesquiterpene and a carbotricyclic compound. | | General Description | (+)-Ledene is a naturally occurring sesquiterpene that can be prepared from (+)-aromadendrene via isomerization. | | References | [1] DUC N.
