The new styrylpyrone derivative, viz. 4-methoxy-3-methylgoniothalamin (1), and the known compound sulochrin were isolated from the marine-derived fungi Penicillium glabrum and P. implicatum. The structure of compound 1 was determined by X-ray diffraction, 2D NMR spectroscopy, and high-resolution mass spectrometry. It was shown for the first
time that sulochrin increases expression of the protein Hsp70. 相似文献

The fatty-acid composition of seven strains of marine mycelial fungi was studied. GC and GC—MS showed that marine fungi of
the genus Penicillium synthesized fatty-acid mixtures of saturated and unsaturated acids of similar compositions with different percent contents.
Fatty-acid profiles of fungi associated with holothuria Chiridota ochotensis were characterized for the first time. Producers of branched 15:0 and dichloro- and cyclopropane-containing acids were observed.

1,8-Dihydroxy-6-methoxy-3-methyl-9,10-anthracenedione (physcion, 1), 3,4-dihydro-3,6,9-trihydroxy-8-methoxy-3-methyl-1(2H)-anthraceneone (asperflavin, 2), and 2,5-dihydroxy-3-(3-methyl-2-butenyl)-6-[(1E)-1-heptenyl]-benzaldehyde (tetrahydroauroglaucin, 3) were shown to be the main pigments of the marine isolate of the fungus Eurotium repens. In addition to the pigments, the fungal metabolites included the diketopiperazine alkaloid echinulin (4). The structures of the compounds were identified using NMR spectroscopy and mass spectrometry. The cytotoxic activity of
1–3 toward sex cells of the sea urchin Strongylocentrotus intermedius was determined.
