Utahmycin C, a new glycosylated derivative of a rare azaanthraquinone produced by Streptomyces sp. YD248
Chemical investigation of Streptomyces sp. YD248 led to the isolation of utahmycin C (1), a new glycosylated member of the rare bacterial 1,3-dimethyl-2-azaanthraquinone family. Its structure was established by NMR spectroscopy and high-resolution mass spectrometry, revealing a β-D-glucuronic acid substituent attached...
