Five new prenylated indole alkaloids, 17-hydroxynotoamide D (1), 17-O-ethylnotoamide M (2), 10-O-acetylsclerotiamide (3), 10-O-ethylsclerotiamide (4), and 10-O-ethylnotoamide R (5) were isolated from a co-culture of marine-derived fungi Aspergillus sulphureus KMM 4640 and Isaria felina KMM 4639. The structures of 1−5 were determined by detailed analysis of spectroscopic data and by comparison with related known compounds. The absolute configurations of 1−5 were determined by time-dependent densi...

Four new indole-diterpene alkaloids asperindoles A–D (1–4) and the known p-terphenyl derivative 3″-hydroxyterphenyllin (5) were isolated from the marine-derived strain of the fungus Aspergillus sp., associated with an unidentified colonial ascidian. The structures of 1–5 were established by 2D NMR and HRESIMS data. The absolute configurations of all stereocenters of 1–4 were determined by the combination of ROESY data, coupling constants analysis, and biogenetic considerations. Asperindoles C an...

Abstract Seven new triterpene glycosides, erylosides F 8 ( 1 ), V 1 ( 2 ), V 2 ( 3 ), V 3 ( 4 ), W ( 5 ), W 1 ( 6 ) and W 2 ( 7 ), were isolated from a Carribean sponge Erylus goffrilleri collected from the Carribean Sea near the Arrecife-Seco reef (Cuba). Structures of the glycosides were determined using 1 H and 13 C NMR spectroscopy, including 2D NMR procedures ( 1 H– 1 H COSY, 1 H– 13 С HMBC, 1 H– 13 С HSQC and NOESY) and HR ESI mass spectrometry. Erylosides 1 and 4 have 14-carboxy-24,25-dim...

Twelve new polyketides, zosteropenillines A–L (1–12), together with known polyketide pallidopenilline A (13), were isolated from the ethylacetate extract of the fungus Penicillium thomii associated with the seagrass Zostera marina. Their structures were established based on spectroscopic methods. The absolute configuration of zosteropenilline A (1) as 4R, 5S, 8S, 9R, 10R, and 13S was determined by a combination of the modified Mosher’s method, X‐ray analysis, and NOESY data. Absolute configurati...
Eleven new polyketides, pallidopenillines 1–11, were isolated from the alga-derived fungus Penicillium thomii. The structures of these compounds were established based on spectroscopic methods. The absolute configuration of pallidopenilline A (1) as 4R, 5S, 8S, 9R, 10R, 13R was established using a combination of the modified Mosher’s method, X-ray analysis, and NOESY data. The absolute configurations of 2–5 were determined by time-dependent density functional theory calculations of the ECD spect...

Abstract Two new sesterterpenoids, terretonins H ( 1 ) and I ( 2 ), together with two known compounds, strobilactone A ( 3 ) and cerebroside D ( 4 ), were isolated from the lipophilic extract of the marine-derived fungus Aspergillus ustus KMM 4664. The structures of compounds 1 and 2 were determined based on spectroscopic methods and confirmed by X-ray crystallographic analysis of terretonin H. All compounds were tested for cytotoxic and embryotoxic effects using sperm and developing embryos of ...
