| 摘要 | Chemical investigation of an endophytic Streptomyces strain led to the isolation of naphthomycin congeners 1-4. Compound 1 contains a unique phenalene scaffold with a bridged oxetane ring, which was confirmed to be a result of an intramolecular [2 + 2] cycloaddition between the olefin and the ketone in the known compound 4 by chemical conversion. 2 features an unprecedented acenaphthene moiety in the ansamycin class of polyketides. Possible biosynthetic pathways are proposed for 1-3. Compounds 1-3 were tested for cytotoxicity against selected human cancer cell lines and they showed moderate activity, with IC50 values ranging from 10.6 mu M to 32.5 mu M. |
