Background

Acolbifene is a selective estrogen receptor modulator (SERM). It inhibits transcriptional activity of estrogen receptor α (ERα) and ERβ induced by estradiol . It binds to ERs in cytosol from human breast cancer and non-cancerous uterine cells (Kis = 0.047 and 0.042 nM, respectively) and to ERs in cytosol from rat uterine cells (IC50 = 0.44 nM) but not to progesterone or androgen receptors in cytosol from rat uterine and ventral prostate cells (IC50s = 22,500 and >10,000 nM, respectively). Acolbifene inhibits E2-stimulated proliferation of T47D, ZR-75-1, and MCF-7 breast cancer cells (IC50s = 0.146, 0.75, and 0.321 nM, respectively) but not basal proliferation. Acolbifene (50 μg per day) inhibits tumor growth stimulated by estrone in a ZR-75-1 human breast cancer xenograft model in ovariectomized mice. It also inhibits E1-stimulated endometrial epithelium thickening in vivo in ovariectomized mice when administered at a dose of 50 μg per day.

Calculation results:

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
3. All of the above co-solvents are available for purchase on the GlpBio website.
