A. Spinella et al., PREDATOR PREY RELATIONSHIP BETWEEN NAVANAX-INERMIS AND BULLA-GOULDIANA - A CHEMICAL APPROACH, Tetrahedron, 49(15), 1993, pp. 3203-3210
Two new compounds, 5,6-dehydroaglajne-3 (9) and isopulo'upone (10), ha
ve been isolated and characterized, along with the already known niuhi
none-B (7), from Navanax inermis and its prey Bulla gouldiana, firmly
establishing on a chemical basis the predator - prey relationship betw
een this pair of cephalaspidean opisthobranchs. The peculiarity of the
metabolites and their structural analogy with other compounds isolate
d from other cephalaspidean molluscs assign a taxonomic relevance for
them.
