DOXORUBICIN

Description

Background Information:

Doxorubicin hyrdrochloride is an anthracycline antibiotic with
antineoplastic activity. Doxorubicin, isolated from the bacterium
Streptomyces peucetius var. caesius, is the hydroxylated congener of
daunorubicin. Doxorubicin intercalates between base pairs in the DNA
helix, thereby preventing DNA replication and ultimately inhibiting
protein synthesis. Additionally, doxorubicin inhibits topoisomerase II
which results in an increased and stabilized cleavable enzyme-DNA linked
complex during DNA replication and subsequently prevents the ligation
of the nucleotide strand after double-strand breakage. Doxorubicin also
forms oxygen free radicals resulting in cytotoxicity secondary to lipid
peroxidation of cell membrane lipids; the formation of oxygen free
radicals also contributes to the toxicity of the anthracycline
antibiotics, namely the cardiac and cutaneous vascular effects.
