(+)-Ledene Chemical Properties,Uses,Production
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.
