生物活性

製品説明 Dexrazoxane HCl is an intracellular iron chelator, which decreases the formation of superoxide radicals, used as a cardioprotective agent; also an inhibitor of topoisomerase II
in vitro

Dexrazoxane (10 mM), known clinically to limit anthracycline cardiac toxicity, prevents daunorubicin-induced myocyte apoptosis, but not necrosis induced by higher anthracycline concentrations in rat cardiac myocytes. [1] 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. [2] 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. [3] Dexrazoxane is hydrolyzed to its active form intracellularly and binds iron to prevent the formation of superhydroxide radicals, thus preventing mitochondrial destruction. [4]
in vivo

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. [5]
