Abstract:
The structures of the new anthraquinone antitumor antibiotic DC92-B and its photodegradation product DC92-D were determined by their spectral studies. DC92-B and D are pluramycin antibiotics, related to hedamycin which possess a characteristic ring F and a side chain containing a cis-epoxide and terminal dimethyl.
