|Description||Toremifene Citrate is an oral selective estrogen receptor modulator (SERM), used in the treatment of advanced breast cancer.|
Toremifene (7.5 mM) causes approximately 60% of the cells to exhibit morphologic characteristics typical of cells undergoing programmed death, or apoptosis in human breast cancer cells. Toremifene (5-10 mM) results in elevated levels of TRPM-2 and TGF beta 1 mRNAs in in vitro or in vivo grown tumor cells. Toremifene causes growth inhibition of estrogen-sensitive breast cancer cells by inducing some cells to undergo apoptosis and by inhibiting other cells from entering mitosis.  Toremifene induces a dose-dependent level of adducts that is lower than that observed for TAM. Toremifene significantly enhances endogenous DNA adduct formation.  Toremifene affects the cell turnover by inhibiting mitotic activity and modifying abundant spontaneous apoptosis in DMBA-induced rat mammary carcinoma. 
|In vivo||Toremifene, at the highest tested dose, increases the incidence of hepatocellular carcinomas in the DEN-initiated groups to a level one-third that observed with Tamoxifen administration to DEN-initiated rats. Toremifene increases the incidence of hypernephromas in previously DEN-initiated rats.  Toremifene results in aneuploidy in 50% of the cells examined and compared with the 85% level induced by Tamoxifen in female Sprague-Dawley rats. |

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.
