|Description||Endoxifen HCl, the active metabolite of Tamoxifen, ia a potent and selective estrogen receptor antagonist. Phase 2.|
Endoxifen shows anti-estrogenic effects, and decreases the E2-induced PR expression in MCF-7 cells.  Endoxifen also blocks ER-alpha transcriptional activity and inhibits estrogen-induced breast cancer cell proliferation.  In MCF7, HS 578T, and BT-549 cells, Endoxifen significantly inhibits cell proliferation.  Endoxifen also exhibits four-fold higher inhibition on PKC activity compared to tamoxifen.  Endoxifen inhibits the hERG current by preferentially interacting with the activated states of cloned hERG potassium channels with IC50 of 1.6 μM. 
|In vivo||In vivo, Endoxifen (8 mg/kg, ) inhibits growth of MCF-7 human mammary tumor xenografts in mice, showing more potency than Tamoxifen. |

* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (g) = Concentration (mol/L) × Volume (L) × 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.
Answers to questions you may have can be found in the inhibitor handling instructions. Topics include how to prepare stock solutions, how to store inhibitors, and issues that need special attention for cell-based assays and animal experiments.
