Juvabione is the methyl ester of todomatuic acid, both of which are sesquiterpenes (C15) found in the wood of true firs of the genus Abies. They exist as part of a mixture of sesquiterpenes based on the bisabolane scaffold. Sesquiterpenes of this family, known as insect juvenile hormone analogues (IJHA) can mimic juvenile activity in order to inihibit insect reproduction and growth. These compounds can form the second line of defense against insect induced trauma and fungal pathogens.
