dc.description.abstract | A bisquinolizidine alkaloid, petrosin (1) and a series of bis-1-oxaquinolizidine, xestospongins (2–9), were obtained from the ethyl acetate extract of the sponge Oceanapia sp. Petrosin was obtained along with xestospongin- C, D, E, F, G, H, I and J having di-hetro atom rings, from the ethyl acetate extract of the sponge. The compounds exhibited moderate to high activities against some microorganisms and clinical isolates. The structures of the alkaloids were elucidated by NMR and ESIMS spectroscopic data. The structure of petrosin was confirmed by an X-ray diffraction study. | |
