| Abstract: | Two new dimeric bromopyrrole alkaloids, nakamuric acid (1) and its corresponding methyl ester (2), have been isolated from the Indopacific sponge Agelas nakamurai along with the known metabolites sceptrin (3), debromosceptrin (4), and ageliferin (5). Their structures were identified by analysis of spectral data. All compounds inhibited the growth of several Gram-positive and Gram-negative bacteria in the agar plate diffusion assay. |
