Juvabional seem to mean " having the effect of juvabione ".
2.
Juvabione is apparently an insect hormone, presumably ( from the name ) affecting some aspect of physical maturation.
3.
The first sesquiterpene to be formed, ( E )-?-bisabolene ( formed by ( E )-?-bisabolene synthase ), can be further transformed into juvabione and todomatuic acid.
4.
Of particular interest to juvabione biosynthesis ( Scheme 1 ), dissociation of the terminal diphosphate from the FPP precursor generates the ( " E ", " E " )-farnesyl allylic cation, leading to nerolidyl diphosphate ( NPP ).
