Cembrene A, or sometimes neocembrene, is a natural monocyclic diterpene isolated from corals of the genus Nephthea. [1] It is a colorless oil with a faint wax-like odor.
Cembrene A itself has little importance as a chemical entity, being a trail pheromone for termites; [2] however, the chemical structure of cembrene is central to a very wide variety of other natural products found both in plants and in animals. [3]
Cembrenes are biosynthesized by macrocyclization of geranylgeranyl pyrophosphate. [3]
