Albidopyrone, a new α-pyrone-containing metabolite from marine-derived Streptomyces sp. NTK 227

摘要

Albidopyrone, a new α-pyrone-containing secondary metabolite, was produced by Streptomyces sp. NTK 227, a strain isolated from Atlantic Ocean sediment and found to be a member of the Streptomyces albidoflavus 16S rRNA gene clade. The structure of the compound was determined by MS and NMR spectroscopy, and found to have a moderate inhibitory activity against protein-tyrosin phosphatase B.
