Metabolite Identification
Common NameOryzalexin S
DescriptionOryzalexin S belongs to the class of organic compounds known as stemarane diterpenoids. These are diterpenoids with a structure characterized by a stemarane skeleton. Some characteristics include the bicyclic system C/D that is constituted by a bicyclo[3.2.1]octane fused to the bicyclic A/B system in a different fashion with respect to other tetracyclic diterpenes possessing the bicyclo[3.2.1]octane system. Moreover, the two contiguous quaternary carbon atoms, C(9) and C(10), are present, the former being a spirocyclic atom. Oxygenation can happen at positions C(2), C(7), C(13), C(17), C(18), and C(19). Oryzalexin S is an extremely weak basic (essentially neutral) compound (based on its pKa).
