Two new bromopyrrole alkaloids, dispyrin (6) and dibromoagelaspongin methyl ether (12), were isolated from the Caribbean sponge Agelas dispar, collected near the Venezuelan island La Blanquilla, and their structures were elucidated from spectroscopic data analysis. Dispyrin (6) contains a novel bromopyrrole tyramine motif that has no precedent in marine natural products chemistry and represents a notable variation from the oroidin class compounds consistently produced by species of Agelasin general. Compounds isolated from Caribbean Agelasspecies were found to possess a unique biogeographical bromination trend. |
