Abstract

Three new minor components, the pyridoacridine alkaloids 1-hydroxy-deoxyamphimedine (1), 3-hydroxy-deoxyamphimedine (2), debromopetrosamine (3), and three known compounds, amphimedine (4), neoamphimedine (5) and deoxyamphimedine (6), have been isolated from the sponge Xestospongia cf. carbonaria, collected in Palau. Structures were assigned on the basis of extensive 1D and 2D NMR studies as well as analysis by HRESIMS. Compounds 16 were evaluated in a zebrafish phenotype-based assay. Amphimedine (4) was the only compound that caused a phenotype in zebrafish embryos at 30 µM. No phenotype other than death was observed for compounds 13, 5, 6.
Keywords: pyridoacridine alkaloids; Xestospongia cf. carbonaria; zebrafish pyridoacridine alkaloids; Xestospongia cf. carbonaria; zebrafish
