| online analysis of xestodecalactones a-c, novel bioactive metabolites from the fungus penicillium cf. montanense and their subsequent isolation from the sponge xestospongia exigua. | fungal isolates of penicillium cf. montanense were obtained from the marine sponge xestospongia exiguacollected from the bali sea, indonesia. culture filtrates of the fungi yielded three novel decalactone metabolites, xestodecalactones a, b, and c (1, 2a, and 2b), consisting of 10-membered macrolides with a fused 1,3-dihydroxybenzene ring. online hplc-nmr, esi-ms/ms, and -cd spectra were acquired, and the structures of the new compounds were established and confirmed on the basis of offline nmr ... | 2002 | 12444683 |
