Sea hares, which have very high medicinal value, are shell-less and slow-moving marine mollusks that feed on various algae and are known to be a rich source of bioactive secondary metabolites, mainly terpenoids, acetogenins, macrolides, and peptides. For example, a novel triazabicyclo[3.2.1]octane aplaminal showed potent cytotoxic activity against HeLa S3 . Another compound, 24-membered macrolide aplyronine A, a potent antitumor substance, exhibited exceedingly potent antitumor activity in vivo against P388 murine leukemia, Lewis lung carcinoma, Ehrlich carcinoma, colon 26 carcinoma, and B16 melanoma . In the course of our search for biologically natural products from marine invertebrates and their derivedfungi collected from the South China Sea, we found that the EtOAc crude extract of the sea hare Aplysia pulmonicadisplayed obvious toxic activity against brine shrimp at a concentration of 100 μg/mL. As we know, there is no related report of the secondary metabolites from this...
