|Description||Dexrazoxane HCl (ICRF-187, ADR-529) is an intracellular iron chelator, which decreases the formation of superoxide radicals, used as a cardioprotective agent; also an inhibitor of topoisomerase II|
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.  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. 
|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. |

1.Please make sure the liquid is clear before adding the next solvent.
2.Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
