Lamellarins O and P: New Aromatic Metabolites From the Australian Marine Sponge Dendrilla cactos
Australian Journal of Chemistry
47(10) 1919 - 1924
A specimen of Dendrilla cactos collected during trawling operations in Bass Strait, Australia, has yielded two new alkaloids, lamellarin-O (17) and lamellarin-P (18). Both these metabolites are examples of the lamellarin structure class, previously reported from tunicates and a mollusc; however, in these examples the pyrrole ring system is not fused to adjacent aromatic rings. The structures of (17) and (18) were secured by spectroscopic analysis and partial synthesis.
