| Common Name | neocembrene |
|---|
| 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. neocembrene is found in Alligator sinensis, Cedrela odorata, Commiphora wightii, Garcinia paucinervis, Cubitermes ugandensis, Perilla frutescens, Sarcophyton trocheliophorum and Sinularia flexibilis. neocembrene 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). |
