Expected Taxonomic Range: Gossypium

Summary:
Lacinilene C is a cotton terpenoid derived from cadinene, which is also a precursor for gossypol biosynthesis. 8-hydroxylation of cadinene leads to gossypol, whereas 7-hydroxylation leads to lacinilene. 7-hydroxylated cadinanes, such as 2,7-dihydroxycadalene and lacinilene C, are phytoalexins induced to accumulate in the foliar tissues after bacteria attack. Inhalation of lacinilene C 7-methyl ether from cotton processing dust was thought to be the cause of chronic respiration distress seen in some fiber mill workers.

The occurrence of the lacinilenes in an optically active form indicates that they are formed enzymatically in vivo. They can also be formed non-enzymatically by in vitro auto-oxidation of 2,7-dihydroxycadalene [Stipanovic81].
