Bleomycin complex (as sulfate salts)
Blenoxane; Blexane; Bleo

Bleomycin is a complex of 11 glycopeptide antitumor antibiotics originally isolated from Streptomyces verticillus in 1972. The dominant components of the complex are bleomycin A2 and B2 and typically represent >90% of the total weight with the remainder comprising the minor analogues. Bleomycins have found clinical application in the treatment of a range of tumors. Bleomycins act by intercalation of DNA and RNA. In the presence of oxygen and metal ions, notably copper and iron, bleomycins form a pseudo- enzyme that induces DNA cleavage.

Solubility: Soluble in water, methanol with moderate ethanol solubility
