Potent And Potentially Non-Cardiotoxic Anthracyclines: Their Synthesis, Biological Evaluation, And Comparison Of Hydrozone-Mediated Reductions, Jerrett Holdaway

Boise State University Theses and Dissertations

After nearly half a century since medical approval, the anthracycline doxorubicin (DOX) remains one of the most potent and clinically useful anticancer agents. In spite of its long history, however, the cytotoxic mechanisms of DOX have been debated and remain controversial. Several well-supported mechanisms will be discussed, such as the potential to intercalate DNA and induce apoptosis through topoisomerase poisoning, free radical formation, and DNA cross-linking. While DOX has substantial medical importance, it is plagued by a life-threatening dose-dependent cardiotoxic side effect associated with several structural groups. A number of modifications to DOX have been accomplished to attempt to remove …
