Chromomycin A3 is the major component of the chromomycin complex of the aureolic acid class, isolated from several Streptomyces species and first reported in 1960. Chromomycin A3 exhibits a broad biological profile as an antibacterial, antifungal and antitumor agent. It binds reversibly to GC-specific DNA ligand in the minor groove which inhibits transcription, DNA gyrase and topoisomerase II. The intense UV spectrum and strong fluorescence makes chromomycin a useful stain for DNA. Source: Chromomycin A3 from Stretomyces griseus.
