| Common Name | cembrene A |
|---|
| Description | Neocembrene 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. Thus, neocembrene is considered to be an isoprenoid lipid molecule. cembrene A was first documented in 2016 (PMID: 27641747). Neocembrene is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral (PMID: 32810428) (PMID: 32529331) (PMID: 30388767). |
