title: Metabolic products of microorganisms. 254. Structure of the new nikkomycins pseudo-Z and pseudo-J.
abstract: Two new nikkomycins were isolated from the fermentation broth of Streptomyces tendae Tü 901/PF 53+-3. These new metabolites, nikkomycins pseudo-Z (psi-Z,1) and pseudo-J (psi-J, 2) differ from the corresponding nikkomycins Z and J by a C-glycosidic bond between C-5 of uracil and C-1' of 5-amino-5-deoxy-D-allo-furanuronic acid instead of an N-glycosidic bond. The structure elucidation was achieved by two-dimensional NMR techniques and mass spectrometry.
