Multiple Defensive Roles for Bromopyrrole Alkaloids from Caribbean Agelas Sponges
Previous studies have indicated that Caribbean reef sponges of the common genus Agelas are chemically defended from fish predators by brominated pyrrole alkaloids: Agelas clathrodes and A. wiedenmayeri by 4,5-dibromopyrrole-2-carboxylic acid (1) and oroidin (2), A. conifera by sceptrin (3). In this study, we expand our understanding of chemical defense in this sponge genus to include an extensi...
متن کاملMonobromoisophakellin, a new bromopyrrole alkaloid from the Caribbean sponge Agelas sp.
A detailed analysis of the chemical constituents of a Caribbean specimen of Agelas sp. was carried out. Four brominated compounds (1-4) were isolated and one of them was identified as a new bromopyrrole metabolite, monobromoisophakellin (1). The structure of 1 was determined using spectroscopic methods. All compounds were tested for their antifeedant activity against the Caribbean reef fish Tha...
متن کاملSventrin, a new bromopyrrole alkaloid from the Caribbean sponge Agelas sventres.
A detailed analysis of the secondary metabolites of a specimen of Agelas sventres was carried out here for the first time. The chemistry of Agelas sponges is dominated by bromopyrrole derivatives. Besides three known bromopyrrole metabolites, a new compound, sventrin (1), was isolated and its structure identified using spectroscopic methods. Sventrin (1) was shown to be a feeding deterrent comp...
متن کاملNew antifeedant bromopyrrole alkaloid from the Caribbean sponge Stylissa caribica.
In this first report on the chemistry of the sponge Stylissa caribica, two known bromopyrrole metabolites and a new compound, N-methyldibromoisophakellin (1), were isolated and identified. The structure of 1 was determined using spectroscopic methods and the computer program COCON. N-Methyldibromoisophakellin (1) was shown to be the only secondary metabolite in Stylissa caribica that, at its na...
متن کاملBromotyrosine-derived alkaloids from the Caribbean sponge Aplysina lacunosa
Three new bromotyrosine-derived alkaloids 14-debromo-11-deoxyfistularin-3 (1), aplysinin A (2), and aplysinin B (3), together with 15 known compounds (4-18) were isolated from the sponge Aplysina lacunosa collected from Stirrup Cay, Bahamas. The structures of the isolated compounds were identified on the basis of MS and NMR data analysis. The (13)C NMR assignment of spirocyclohexadienylisoxazol...
