摘要

A bioassay-guided fractionation of the crude methanol extract of the myxobacterium Hyalangium minutum, strain NOCB-2(T) (DSM 14724(T)), led to the isolation of hyaladione (1), a novel S-methyl cyclohexadiene-dione. The structure of 1 was established by HRESIMS, NMR, and IR spectroscopy as well as X-ray crystallography. Compound 1 was active against growing mammalian cell lines, with IC50 values ranging from 1.23 to 3.93 mu M, in addition to a broad spectrum of antibacterial and antifungal activities, including inhibition of pathogenic methicillin-resistant Staphylococcus aureus and Pseudomonas aeruginosa with an MIC of 0.83 and 8.5 mu g mL(-1), respectively.
