Estramustine
Based on 1 publication(s) in Google Scholar
Estramustine, an estradiol analog, is an orally active antimicrotubule chemotherapy agent. Estramustine depolymerises microtubules by binding to microtubule associated proteins (MAPs) and/or to tubulin. Estramustine can interfere mitosis, trigger cell death and induce apoptosis, which can be used for the research of cancer like prostate cancer.

Estramustine (1 µg/mL, 48 h) suppresses PC3 cell growth[1]. Estramustine (2 µg/mL, 48 h) elevates phosphatidylserine eversion amount on PC3 cells and induces PC3 cell apoptosis through reducing miR-31[1]. Estramustine (0-40 µM, 24-72 h) inhibits cell proliferation and tubulin cytoskeleton in RAW 264.7 cells[2]. Estramustine (10 µM, 24 h) inhibits TGF-β-induced RAW 264.7 cell migration, as well as TGF-β-induced uPA production by inhibiting Smad3 activation[2].

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.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (5.68 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (5.68 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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.
