Description

Elacestrant (RAD1901) is an orally available and selective estrogen receptor degrader (SERD) with IC50s of 48 and 870 nM for ERα and ERβ, respectively. Elacestrant also can inhibit growth of ER+ breast cancer cell lines in vitro and in vivo[1][2].

In Vitro

Elacestrant (RAD1901; 0.5 nM-10 µM; 48 h) exhibits dose-dependent inhibition of ERα expression, with a EC50 of 0.6 nM in MCF-7 cells[1].
Elacestrant (0-1 µM; 48 h) inhibits proliferation of Estradiol (E2)-stimulated MCF-7 cells in a dose-dependent manner, with an EC50 of 4 pM[1].
Elacestrant (0-1 µM; 24 or 48 h) results in a dose-dependent and marked decrease in estrogen receptor protein expression in MCF7, T47D, and HCC1428 cells[2].
Elacestrant (0.01, 0.1, 1.0 µM) decreases expression of progesterone receptor (PGR, PR; an ER target gene), in both MCF7 and T47D cell lines[2].

Cell Proliferation Assay[1]

Cell Line: ER-positive MCF-7 cells (Estradiol (E2)-stimulated)[1]
Concentration: 0-1 µM
Incubation Time: 48 h
Result: Showed antiproliferative activity on cells.

Western Blot Analysis[1]

Cell Line: MCF-7 cells
Concentration: 0.5 nM-10 µM
Incubation Time: 48 h
Result: Inhibited ERα expression (EC50 of 0.6 nM) in a dose-dependent manner.

Western Blot Analysis[2]

Cell Line: MCF7, T47D, and HCC1428 cells
Concentration: 0-1 µM
Incubation Time: 24 or 48 h
Result: Decreased the expression of estrogen receptor protein.
In Vivo

Elacestrant (0.3-120 mg/kg; p.o.; single daily for 40 days) antagonizes E2-mediated uterine stimulation in a dose-dependent manner in vivo[1].
Elacestrant (30, 60 mg/kg; p.o.; single daily for 4 weeks) induces complete tumor growth inhibition in mice[2].
Tumor growth inhibition is maintained for 4 weeks after Elacestrant withdrawal[2].

* Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month (sealed storage, away from moisture and light). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 4 mg/mL (8.72 mM); Clear solution

    This protocol yields a clear solution of ≥ 4 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (40.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

    Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: ≥ 4 mg/mL (8.72 mM); Clear solution

    This protocol yields a clear solution of ≥ 4 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (40.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
