Polycitone B and Prepolycitrin A: Two Novel Alkaloids from the Marine Ascidian Polycitor africanus
Two novel compounds, polycitone B (4) and prepolycitrin A (3), were isolated from the marine ascidian Polycitor africanus. The structures of these new dibromotyrosine metabolites were established mainly on the basis of NMR spectroscopic data. Isolation of compound 3 supports the earlier suggestion t...

| description | Two novel compounds, polycitone B (4) and prepolycitrin A (3), were isolated from the marine ascidian Polycitor africanus. The structures of these new dibromotyrosine metabolites were established mainly on the basis of NMR spectroscopic data. Isolation of compound 3 supports the earlier suggestion that it is the bioprecursor of polycitrin A (2). |
