N. Lindquist et al., Corydendramines A and B, defensive natural products of the marine hydroid Corydendrium parasiticum, J NAT PROD, 63(9), 2000, pp. 1290-1291
Two novel piperidinol metabolites, corydendramines A (1) and B (2), have be
en isolated from the marine hydroid Corydendrium parasiticum. The structure
s of these compounds, which deter feeding by a potential hydroid predator,
were determined by interpretation of their spectral data.
