Аннотация

Five new eudesmane-type sesquiterpenes – thomimarines A-E (1-5) and 12 new polyketides with “decalin” moiety – zosteropenillines A-L (6-17) were isolated from the ethylacetate extract of the fungi Penicillium thomii associated with the seagrass Zostera marina. Their structures were established based on spectroscopic methods. The absolute configurations of 1–5 and 7-10 were determined by time-dependent density functional theory (TD-DFT) calculations of ECD spectra. The absolute configuration of zosteropenilline A (6) was determined by a combination of the modified Mosher’s method, X‐ray analysis, and NOESY data. The effect of selected compounds on the viability of human drug‐resistant prostate cancer cells PC3 as well as on autophagy in these cancer cells and inhibitory effects of selected compounds on NO production in LPS‐induced RAW 264.7 murine macrophages were evaluated.
