Sesquiterpene molecule from Haminoea cymbalum

April 15, 2001
From: Brett Baker

I need to know the molecular formula and structure of the biosynthetic precursor that will produce the chemical agent, "kumepaloxane" which is discharged by the Haminoea cymbalum slug.
Can anyone help?

Dear Brett,
I only know of the original reference:
Poiner, A. Paul, V.J. & Scheuer, P.J. (1989) Kumepaloxane, a rearranged trisnor sesquiterpene from the bubble-shell Haminoea cymbalum. Tetrahedron, 45(3): 617-22

The molecule is perhaps an antifeedant chemical produced by the slug, which makes the slug distasteful to predators.
Best wishes,
Bill Rudman
