Alcalóides alquilpiridínicos de esponjas marinhas

Abstract: Recebido em 8/3/96; aceito em 29/8/96 ALKYLPYRIDINE ALKALOIDS FROM MARINE SPONGES. 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).Keywords: marine sponges; alkylpyridine alkaloids. REVISÃO INTRODUÇÃOEspon… Show more

“…Sponges of the order Haplosclerida, such as those belonging to genera Callyspongia, Haliclona, Niphates and Pachychalina, are a remarkable source of bioactive alkylpyridine and alkylpiperidine alkaloids (reviewed in Andersen et al, 1996;Almeida et al, 1997;Berlinck, 2007). In our screening, sponges of these four genera yielded active crude extracts in several of the bioassays, some of them with a high activity level.…”

“…Comprehensive reviews of this structural class of secondary metabolites have appeared in 1996, 2 1997, 3 and 2000. 4,5 Not only are these alkaloids considered chemotaxonomic markers of Haplosclerid sponges, 2,3 but many of them present potent biological activities.…”

“…[4][5][6][7][8][9][10] Marine sponges are a prolific source of a huge variety of secondary metabolites. [11][12][13][14][15] Sponges of the order Verongida, and the family Aplysinidae, characterized by the absence of terpenes and the production of steroids, produce a wide diversity of bromotyrosine-containing metabolites with interesting biological properties. 16 The richest sources of biogenetically, tyrosine--derived bromo-containing amines, are members of the Verongida order, and the genus Aplysina.…”
