چکیده

The molecular formula of a new antimetabolite produced by Streptomyces purpurascens was determined to be C5H5N5O2 by elemental analysis, FD-MS and 13C NMR. Reduction of this antimetabolite with Raney nickel yielded guanine. The antimetabolite was distinguishable from known N-hydroxyguanines by comparison of their UV spectra. The structure of the antimetabolite was finally established to be 7-hydroxyguanine by X-ray crystallography.

Novel antitumor antibiotics, saptomycins. II. Isolation, physico-chemical properties and structure elucidation.

A complex of novel antitumor antibiotics related to the pluramycin-group was isolated from the fermentation of actinomycete, named Streptomyces sp. HP530. The producing strain mutated frequently. The products isolated from the parent strain were designated saptomycins A, B, C1, C2 and F, while those of the mutant were named saptomycins D, E, G and H. These structures were elucidated by several ...
