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].

- 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).
