(+)-Ledene Chemical Properties,Usage,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.
