藥理
Antineoplastic Agent, Anthracycline; Topoisomerase II Inhibitor
Doxorubicin inhibits DNA and RNA synthesis by intercalation between DNA base pairs by inhibition of topoisomerase II and by steric obstruction. Doxorubicin is also a powerful iron chelator; the iron-doxorubicin complex can bind DNA and cell membranes and produce free radicals that immediately cleave the DNA and cell membranes.
