Two new metabolites including a new aszonalenin analogue (1c) and a new meroditerpene (3) were isolated, together with aszonalenin (1a), acetylaszonalenin (1b), 13-oxofumitremorgin B (2), aszonapyrone A (4b) and helvolic acid, from the culture of the soil fungus Neosartorya fischeri (KUFC 6344). While the ethyl acetate extract of the culture of the diseased coral-derived fungus Neosartorya laciniosa (KUFC 7896) furnished aszonapyrone B (4a), aszonapyrone A (4b), tryptoquivaline L and 3′-(4-oxoquinazolin-3-yl) spiro[1H-indole-3,5′-oxolane]-2,2′-dione, the ethyl acetate extract of the culture of the marine sponge-associated fungus Neosartorya tsunodae (KUFC 9213) yielded a new analogue of chevalone C (5) and helvolic acid. The structures of the new compounds were established based on 1D and 2D NMR spectral analysis as well as HR-ESIMS. Compounds 1a–c, 2, 3, 4a, 4b and 5 were evaluated for their in vitro growth inhibitory activity on the MCF-7 (breast adenocarcinoma), NCI-H460 (non-small cell lung cancer) and A375-C5 (melanoma) cell lines by the protein binding dye SRB method. 相似文献

Chemical investigation of a collection of the fungus Neosartorya glabra from Thailand furnished sartoryglabins A-C (1a, 1b and 2) which are analogs of the reverse prenylated indole alkaloids known as (-) ardeemins. Structures of these compounds were established by NMR spectrometry and an X-ray analysis. Sartoryglabins A-C were evaluated for their in vitro growth inhibitory activity on three human tumor cell lines: MCF-7 (breast adenocarcinoma), NCI-H460 (non-small cell lung cancer) and A375-C5 (melanoma). All the compounds exhibited strong to moderate activity against the MCF-7 cell line but weak or no activity against the NCI-H460 and A375-C5 cell lines. Sartoryglabin B was found to exhibit selectivity towards the MCF-7 cell line. 相似文献
