Article abstract of DOI:10.1016/S0040-4020(01)91443-7

From the aqueous extracts of the New Caledonian sponge, Pseudaxinyssa cantharella, nine pyrrolic metabolites have been isolated.Four are new: dibromocantharelline 8, odiline 22 and compounds 18 and 24.The structures of 8, 22 and 18 were determined from spectral data and that of 8 was comfirmed by X-ray studies.A fifth, 17, had been prepared previously but is isolated for the first time from a natural source.The last four are known but are isolated for the first time from the genus Pseudaxinyssa: oroidine 1, compounds 2 and 3, and (+)-dibromophakelline 4, the enantiomer of a known compound: its structure was comfirmed by X-ray diffraction.
