Adriamycin and its derivatives are among the most efficient antimitotics used in clinical therapy. A specific cardiotoxicity places a limit on the total dose of adriamycin that may be administered. The mechanism of cardiac toxicity is complex. Data accumulated from in vitro and in vivo studies indicate a possible common cause for the inhibition of numerous enzymes and tissue degradation by a free radical mechanism: the binding of adriamycin to the inner mitochondrial membrane cardiolipin. The structure of the adriamycin-cardiolipin complex has been investigated by using physico-chemical techniques and via conformational analysis. The results open a rational way to design new structures that are less cardiotoxic., SCOPUS: re.j, info:eu-repo/semantics/published
