MedKoo CAT#: 100090

CAS#: 9041-93-4 (sulfate)

Description: Bleomycin sulfate is a mixture of the sulfate salts of basic glycopeptide antineoplastic antibiotics isolated from Streptomyces verticillus. Bleomycin sulfate forms complexes with iron that reduce molecular oxygen to superoxide and hydroxyl radicals which cause single- and double-stranded breaks in DNA; these reactive oxygen species also induce lipid peroxidation, carbohydrate oxidation, and alterations in prostaglandin synthesis and degradation.

Additional Information

Bleomycin is a glycopeptide antibiotic produced by the bacterium Streptomyces verticillus. Bleomycin refers to a family of structurally related compounds. When used as an anticancer agent, the chemotherapeutical forms are primarily bleomycin A2 and B2. The drug is used in the treatment of Hodgkin's lymphoma (as a component of the ABVD and BEACOPP regimen), squamous cell carcinomas, and testicular cancer, as well as in the treatment of plantar warts  and as a means of effecting pleurodesis.  The mechanism of action involves breaking DNA. Bleomycin is on the World Health Organization's List of Essential Medicines that are needed for a basic health system.
Mechanism of Action
Although the exact mechanism of action of BLENOXANE is unknown, available evidence indicates that the main mode of action is the inhibition of DNA synthesis with some evidence of lesser inhibition of RNA and protein synthesis. Bleomycin is known to cause single, and to a lesser extent, double-stranded breaks in DNA. In in vitro and in vivo experiments, bleomycin has been shown to cause cell cycle arrest in G2 and in mitosis. When administered into the pleural cavity in the treatment of malignant pleural effusion, BLENOXANE acts as a sclerosing agent.
