Description

Raloxifene hydrochloride (Keoxifene hydrochloride) is a second generation selective and orally active estrogen receptor modulator. Raloxifene hydrochloride produces estrogen-agonistic effects on bone and lipid metabolism and estrogen-antagonistic effects on uterine endometrium and breast tissue[1].

IC50 & Target

IC50: estrogen receptor[1]

In Vitro

Raloxifene activates TGF beta 3 promoter as a full agonist at nanomolar concentrations, and raloxifene inhibits the estrogen response element-containing vitellogenin promoter expression as a pure estrogen antagonist in transient transfection assays[1].
Raloxifene is a potent uncompetitive inhibitor of human liver aldehyde oxidase-catalyzed oxidation of phthalazine, vanillin, and nicotine-Delta1'(5')-iminium ion, exhibits Ki values of 0.87 to 1.4 nM[2].
Raloxifene is also a noncompetitive inhibitor of an aldehyde oxidase-catalyzed reduction reaction of a hydroxamic acid-containing compound, with a Ki value of 51 nM[2].
Raloxifene (0-80 μM; 48 hours) significantly decreased in mouse mammary carcinoma BJMC3879luc2 cells viability as a concentration manner in BJMC3879luc2 cells[5].

Cell Viability Assay[5]

Cell Line: BJMC3879luc2 cells 
Concentration: 0 μM, 10 μM, 20 μM, 40 μM, 80 μM
Incubation Time: 48 hours
Result: Reduced BJMC3879luc2 cell viability.
In Vivo

Raloxifene (3 mg/kg; once daily) has potent estrogenic activity on bone resorption and serum cholesterol, a lesser effect on bone formation, and minimal activity on uterine wet weight in ovariectomized (OVX) rats[3].
Raloxifene (oral administration; 0.1 mg/kg-10 mg/kg; 5 weeks) increases bone mineral density in the distal femur and proximal tibia. It reduces serum cholesteroloral with ED50 of 0.2 mg/kg in ovariectomized (OVX) rat[4].
Raloxifene (subcutaneously implanted mini-osmotic pumps; 18 or 27 mg/kg; once daily; 6 weeks) significantly suppresses tumor volumes in mice, in addition, the multiplicity of lymph node metastasis is also significantly decreased[5].

* Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month (sealed storage, away from moisture). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.5 mg/mL (4.90 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

    Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: ≥ 2.5 mg/mL (4.90 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
