Alcalóides alquilpiridínicos de esponjas marinhas Alkylpyridine alkaloids from marine sponges

Abstract

The chemistry of alkylpyridine alkaloids originating from marine sponges is comprehensively reviewed, with emphasis on their natural occurrence, methods for their isolation, spectroscopic characterization, biological activities e chemical synthesis. A likely chemotaxonomic role is suggested, as markers for sponges of the Order Haplosclerida (Demospongiae).
