Ospemifene
Based on 3 publication(s) in Google Scholar
Ospemifene (FC-1271a) is an orally active and non-estrogenic selective estrogen receptor modulator (SERM) with Ki values of 380 and 410 nM for estrogen receptor α (ERα) and ERβ, respectively. Ospemifene inhibits caspase-3 activity. Ospemifene inhibits neuronal degeneration, prevents bone loss, and increases vaginal weight and vaginal epithelial height. Ospemifene has anticancer activity against breast cancer.

Ospemifene (100 pM-30 μM) binds with essentially comparable affinity to the ER-α and ER-β isoforms and effectively antagonize ERE-mediated transactivation in MCF-7 cells[1].
Ospemifene (0.1 nM-10 μM) does not significantly promote the growth of MCF-7 cells[3].
Ospemifene (0.1-10 μM; 4-6 days) inhibits the growth of MCF-7 cells and has no significant effect on the growth of MDA-MB-231 cells[4].
Ospemifene (0.1-10 μM; posttreatment) decreases hypoxia- and ischemia- induced LDH release, caspase-3 activity, neuronal cell degeneration in primary neocortical cell cultures subjected to hypoxia and/or ischemia[5].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Ospemifene (1-10 mg/kg; p.o.; 4 weeks) can prevent bone loss, maintain the trabecular bone volume of the distal femur, prevent the decrease of bone strength in ovariectomized rats[3].
Ospemifene (10-100 mg/kg; p.o.; once daily; 7 days) inhibits the growth of MCF-7 tumors in the athymic, ovariectomized mouse model with MCF-7 human tumor xenografts[4].
Ospemifene (5-50 mg/kg; p.o.; daily) effectively prevents breast cancer in the MTag.Tg transgenic mouse model[6].

Prevented the OVX-induced increase in serum cholesterol in a dose-dependent manner.
Had no significant effect on uterine wet weight or morphology at 0.1 or 1 mg/kg.
Had a slightly estrogenic effect at 10 mg/kg.
-
Animal Model:Female Sprague Dawley rats, DMBA (HY-W011845)-induced breast carcinoma model[3]
-
Dosage:10 mg/kg, 50 mg/kg
-
Administration:Orally, 4 weeks
-
Result:Reduced the number of breast tumors.
Reduced the number of growing tumors, increased the number of dormant or regressing tumors, and even caused some tumors to disappear.
-
Animal Model:Female athymic nude mice (8-12 weeks old; nu/nu-BALB/cABom), MCF-7 cell-transplanted tumor model after OVX and estrogen supplementation[3]
-
Dosage:1 mg/kg, 10 mg/kg, 50 mg/kg
-
Administration:Oral gavage (p.o.), 48 days
-

Had no effect at 1 mg/kg and resulted in slower tumor regression at 10 or 50 mg/kg.
