Product Description

Endoxifen HCl (Z-Endoxifen; N-Desmethyl-4-hydroxytamoxifen), the hydrochloride salt of endoxifen which is an active metabolite of Tamoxifen, is a potent and selective estrogen receptor antagonist/SERM with potential anticancer activity. It has been found to be effective in patients that have failed previous hormonal therapies. 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.

Biological Activity I Assay Protocols (From Reference)
ln Vitro

In vitro activity: 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


Cell Assay: MCF7 and Ishikawa cells are grown in 10% triple charcoal-stripped serum-containing medium for 3 d. The cells are then plated at a density of 2,000 cells per well in 96-well tissue culture plates and treated as indicated every 48 h. Cell proliferation assays are conducted 8 days after the first treatment using a CellTiter-Glo Luminescent Cell Viability kit according to the manufacturers protocol.

ln Vivo
In vivo, Endoxifen (8 mg/kg, ) inhibits growth of MCF-7 human mammary tumor xenografts in mice, showing more potency than Tamoxifen.
Animal Protocol
Dissolved in water; 8 mg/kg; Oral gavage
Mice bearing MCF-7 human mammary tumor xenografts

Solubility Data
Solubility (In Vitro)
DMSO: 74 mg/mL (180.5 mM)
Water:<1 mg/mL
Ethanol: 74 mg/mL (180.5 mM)
Solubility (In Vivo)
Solubility in Formulation 1: 2.5 mg/mL (6.10 mM) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), suspension solution; with sonication.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL.
Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution.

Solubility in Formulation 2: 2.5 mg/mL (6.10 mM) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), suspension solution; with ultrasonication.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution.

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

Calculator

Molarity Calculator allows you to calculate the mass, volume, and/or concentration required for a solution, as detailed below:

  • Calculate the Mass of a compound required to prepare a solution of known volume and concentration
  • Calculate the Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Calculate the Concentration of a solution resulting from a known mass of compound in a specific volume
An example of molarity calculation using the molarity calculator is shown below:
What is the mass of compound required to make a 10 mM stock solution in 5 ml of DMSO given that the molecular weight of the compound is 350.26 g/mol?
  • Enter 350.26 in the Molecular Weight (MW) box
  • Enter 10 in the Concentration box and choose the correct unit (mM)
  • Enter 5 in the Volume box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
  • Enter 25 into the Volume (End) box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 62.5 μL (0.1 ml) appears in the Volume (Start) box
