|Description||Raloxifene is an estrogen antagonist, which inhibits human cytosolic aldehyde oxidase-catalyzed phthalazine oxidation activity with IC50 of 5.7 nM.|
|Features||Raloxifene is as effective as tamoxifen in reducing the incidence of breast cancer in postmenopausal women at increased risk.|
Raloxifene, has been demonstrated as a potent uncompetitive inhibitor of human liver aldehyde oxidase-catalyzed oxidation of phthalazine, vanillin, and nicotine-Delta1'(5')-iminium ion, with Ki values of 0.87 nM, 1.2 nM and 1.4 nM. Raloxifene has also been shown to be a noncompetitive inhibitor of an aldehyde oxidase-catalyzed reduction reaction of a hydroxamic acid-containing compound, with a Ki of 51 nM.  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. 
|In vivo||Raloxifene restores both bone mineral density and TGF beta 3 messenger RNA expression in the femur to levels measured in intact rats.  Raloxifene (0.1 mg/kg-10 mg/kg, orally for 5 weeks) increases bone mineral density in the distal femur and proximal tibia in ovariectomized (OVX) rat. Raloxifene reduces serum cholesteroloral with ED50 of 0.2 mg/kg in ovariectomized (OVX) rat. Raloxifene diverges dramatically from estrogen in its lack of significant estrogenic effects on uterine tissue.  Raloxifene prevents cancellous osteopenia as well as the changes in radial bone growth, bone resorption, and blood cholesterol, but is less effective in reducing cancellous bone formation and does not prevent uterine atrophy in ovariectomized (OVX) rats.  Raloxifene (3 mg/kg/day) 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. |
|In vitro||DMSO||100 mg/mL (196.06 mM)|
|In vivo||Add solvents to the product individually and in order(Data is from Selleck tests instead of citations):
For best results, use promptly after mixing.
* 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.
|Synonyms||LY156758 (Keoxifene) HCl|
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.
