摘要
Four novel cyclopentenone derivatives (1-4), characterising a cyclopentenone ring conjugated with a 1,8-dioxadecalin, were isolated from rare actinobacterial strain Actinoalloteichus nanshanensis sp. nov. NEAU 119. The structures of these compounds were elucidated on the basis of extensive spectroscopic analysis. Bioassays indicated that compounds 1-4 showed low cytotoxicities against human leukaemia cell line K562 and human renal carcinoma cell line ACHN. To the best of our knowledge, this is the first example of isolation of C-11 cyclopentenones from actinomycetes.
