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. The intense UV spectrum and strong fluorescence makes chromomycin a useful stain for DNA.
Chromomycin A3 is soluble in ethanol, methanol, DMF and DMSO.
