Dexrazoxane presumably exerts its cardioprotective effects by either binding free or loosely bound iron, or iron complexed to doxorubicin, thus preventing or reducing site-specific oxygen radical production that damages cellular components. Dexrazoxane specifically abolishes the DNA damage signal gamma-H2AX induced by doxorubicin, but not camptothecin or hydrogen peroxide, in H9C2 cardiomyocytes. Dexrazoxane also induces rapid degradation of Top2beta, which paralleles the reduction of doxorubicin-induced DNA damage. Dexrazoxane antagonizes doxorubicin-induced DNA damage through its interference with Top2beta, which could implicate Top2beta in doxorubicin cardiotoxicity. Dexrazoxane is hydrolyzed to its active form intracellularly and binds iron to prevent the formation of superhydroxide radicals, thus preventing mitochondrial destruction. 体内研究:Dexrazoxane combined with doxorubicin, daunorubicin, or idarubicin reduces the tissue lesions in B6D2F1 mice (expressed as area under the curve of wound size times duration) by 96%, 70%, and 87%, respectively. Dexrazoxane combined with doxorubicin, daunorubicin, or idarubicin results in a statistically significant reduction in the fraction of mice with wounds as well as the duration of wounds. 产品信息订购:
