Biological Activity

bazedoxifene hcl is a novel, non-steroidal and indole-based estrogen receptor modulator (serm). the ic50 value of bazedoxifene against erα and erβ is 23 nm and 89 nm, respectively [1,2].the estrogen receptor (er) contains two subtypes, erα and erβ. ers are widely expressed in different tissue types such as kidney, brain, bone, heart, prostate, and endothelial cells. estrogen and the ers have been involved in most cancers such as breast cancer,ovarian cancer,colon cancer,prostate cancer, and endometrial cancer [3].

in vitro

bazedoxifene is a selective serm currently in development for osteoporosis prevention and treatment. bazedoxifene was the third generation serm. in cultured breast cancer (bmcf-7) cells, bazedoxifenedidn’t stimulate erα mediated transcriptional activity and acted as an antagonist to estradiol. similar results were also 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 [2].bazedoxifene didn’t stimulate proliferation of mcf-7 cells but inhibited 17β-estradiol-induced proliferation with an ic50 value of 0.19 nm [4].

in vivo

in an immature rat model, bazedoxifene increased 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. in an immature rat uterine model, bazedoxifene (0.5 and 5.0 mg/kg) was associated with less increase in uterine wet weight than either ethinyl estradiol (10 μg/kg) or raloxifene (0.5 and 5.0 mg/kg) [4].
