Nocardamin glucuronide, a new member of the ferrioxamine siderophores isolated from the ascamycin-producing strain Streptomyces sp. 80H647

A new siderophore glucuronide, nocardamin glucuronide (1), was isolated together with nocardamin (2) by applying the one strain-many compounds (OSMAC) approach to the ascamycin-producing strain, Streptomyces sp. 80H647, and performing multivariate analysis using mass spectral data. Structure elucidation was accomplished by a combination of NMR and MS analyses. The absolute configuration of the glucuronic acid moiety was found to be β-D-GlcA by...
