Abstract
A new sex-aggregation pheromone, sobralene, produced by the sand fly Lutzomyia longipalpis from Sobral (Ceará State, Brazil) is shown to have the novel 6,12-membered ring-fused diterpene structure 3. It is proposed that sobralene is a likely shunt metabolite of the taxadiene synthase-catalysed cyclisation of geranygeranyl diphosphate.

The sand fly species complex Lutzomyia longipalpis is the main carrier of the Protist parasite Leishmania infantum, the causative agent of American visceral leishmaniasis (AVL), a potentially fatal human disease in South and Central America.[1,2]
We have examined the NMR spectroscopic data for the sex-aggregation pheromone produced by the 2-spot L. longipalpis population from Sobral, Brazil
Summary
A new sex-aggregation pheromone and likely shunt metabolite of the taxadiene synthase cascade, produced by a member of the sand fly Lutzomyia longipalpis species complex. A new sex-aggregation pheromone, sobralene, produced by the sand fly Lutzomyia longipalpis from Sobral (Ceará State, Brazil) is shown to have the novel 6,12-membered ring-fused diterpene structure 3.
