| Description | Cembrene, also known as thunbergen or thumbelene, belongs to the class of organic compounds known as cembrane diterpenoids. These are diterpenoids with a structure based a cembrane skeleton, which is characterized by the presence of an isopropyl group at C-1 and by three symmetrically disposed methyl groups a the t C-4, -8 and -12 positions. Cembrene A itself has little importance as chemical entity, being a trail pheromone for termites; however, the chemical structure of cembrene is central to a very wide variety of other natural products found both in plants and in animals. Cembrenes are biosynthesized by macrocyclization of geranylgeranyl pyrophosphate. Cembrene is possibly neutral. Outside of the human body, Cembrene has been detected, but not quantified in, fats and oils and herbs and spices. This could make cembrene a potential biomarker for the consumption of these foods. Cembrene A, or sometimes neocembrene, is a natural monocyclic diterpene isolated from corals of the genus Nephthea. (1z,3e,6z,10z)-14-isopropyl-3,7,11-trimethylcyclotetradeca-1,3,6,10-tetraene is found in Larix lyallii. (1z,3e,6z,10z)-14-isopropyl-3,7,11-trimethylcyclotetradeca-1,3,6,10-tetraene was first documented in 2004 (PMID: 15620244). It is a colorless oil with a faint wax-like odor. |
