Chemical and biological properties of rubiginone, a complex of new antibiotics with vincristine-cytotoxicity potentiating activity.
A novel complex of isotetracenone (angucyclinone) group antibiotics was discovered from the cultured broth of Streptomyces griseorubiginosus No. Q144-2. The antibiotic consisted of six related factors, designated rubiginones A1, A2, B1, B2, C1 and C2. They significantly potentiated cytotoxicity of vincristine (VCR) against VCR-resistant P388 leukemia and Moser cells.
