| In Vitro | In vitroactivity: Bazedoxifene is a third generation selective estrogen receptor modulator (SERM). Bazedoxifene does not stimulate ERα mediated transcriptional activity and acts as an antagonist to estradiol in cultured breast cancer (bMCF-7) cells. Similar results are seen in other cell lines including CHO (ovarian), HepG2 (hepatic) or GTI-7 (neuronal) with bazedoxifene having no ERα agonist activity and acting as an antagonist to estradiol action. Bazedoxifene does not stimulate proliferation of MCF-7 cells but did inhibit 17β-estradiol-induced proliferation with IC50 of 0.19 nM. Kinase Assay: Test compounds are initially solubilized in DMSO and the final concentration of DMSO in the binding assay is ≤ 1%. Eight dilutions of each test compound are used as an unlabelled competitor for [3H]17β-estradiol. Typically, a set of compound dilutions would be tested simultaneously on human, rat and mouse ER-α and ER-β. The results are plotted as measured DPM vs. concentration of test compound. For dose-response curve fitting, a four parameter logistic model on the transformed, weighted data are fit and the IC50 is defined as the concentration of compound decreasing maximum [3H]estradiol binding by 50%. For active compounds, the IC50 is determined at least three times. It should be noted that IC50 values are not direct measures of a ligand’s affinity for the receptor. Rather, they can only be compared as relative values, in this case to 17β-estradiol. Cell Assay: For the proliferation assay, cells are plated at 20,000 cells/well in a 24-well plate in DMEM/F12 (50:50) (phenol red-free) with 10% charcoal/dextran-treated FBS and 1 × GlutaMAX-1. After overnight incubation, the medium is aspirated and treatments in DMEM/F12 (50:50) (phenol red-free) with 2% charcoal/dextran-treated FBS and 1 × GlutaMAX-1 are added to the wells. Each plate has a vehicle (baseline proliferation) and treatments. Treatments included 10 pM 17β-estradiol determined to be the EC80 for 17β-estradiol and 17β-estradiol in combination with six concentrations of BZA. Treatments from d 1 are renewed on d 3 and d 6 by aspirating medium from wells and replacing with fresh medium and treatments. On d 7, cells are detached from the plate using trypsin-EDTA and counted using a Multisizer II. |

| In Vivo | In an immature rat model, bazedoxifene increases uterine wet weight 35% at a dose of 0.5 mg/kg compared to an 85% increase with raloxifene at the same dose and a 300% increase in uterine weight with ethinyl estradiol at a dose of 10 μg/kg. Ovarectomized rats treated with 0.3 mg/d bazedoxifene displayed maintenance of bone mass and bone strength similar to effects seen with 2 μg/d ethinyl estradiol, 3 mg/d raloxifene, or sham operated animals. |
