Abstmct Two new compounds, 5,6-dehydmaglajne-3 (9) and Isopulo'upone (lo), have been isolated and characterwd. along with the already known muhmone-B ('I), from Navanax tnermls and Us prey Bulla gouldtuna. firmly estabbshlng on a cbenucal basts the predator -prey relauonshlp between tb~s pau of cepbakp&an oplstbobrancbs Tbe pecubanty of the metabohtes and theu stn~ctural analogy wth other compounds Isolated from other cephalaspldean molluscs awgn a taxonomlc relevance for them

Opisthohranchs are manne molluscs which, being scarcely protected by the shell, have been object of many chermcal studies dnected to mvesngate their defensive strategies 3 The major attentton has been devoted to nudrbranchs which, be.mg completely devoid of shell, are considered the most evolute opisthobranchs On the contrary, only a few papers have reported chemical studies on the shelled cephalaqdeans even though chemical commumcatton seems to play an important role for some species belongmg to this order 4-8 The study on the
