β-Estradiol 17-acetate
Based on 1 publication(s) in Google Scholar
β-Estradiol 17-acetate (1,3,5(10)-Estratriene-3,17β-diol 17-acetate) is a long-acting endogenous estrogen precursor and also a cell viability and proliferation enhancer. β-Estradiol 17-acetate promotes the adhesion and proliferation of freshly isolated and revived female-derived human brain microvascular endothelial cells, and reverses the decreased viability of revived male-derived human brain microvascular endothelial cells. β-Estradiol 17-acetate exerts the microvascular protective effect of estrogen, enabling non-tumor human brain microvascular endothelial cells to be cultured in vitro for 2 months after cryopreservation. β-Estradiol 17-acetate is biotransformed into β-estradiol via hydrolase action in the in vitro skin of humans, hairless dogs, rats and hairless mice.

Biological Activity
β-Estradiol 17-acetate (10 nM; 22 d) potently enhances the adhesion and proliferation capacities of hBMEC derived from postmenopausal female patients, and significantly increases the cell density of hBMEC derived from male patients[1].
β-Estradiol 17-acetate (10 nM; 33 d) maintains the viability and sustained proliferative capacity of hBMEC derived from postmenopausal female patients, whereas withdrawal of this hormone causes irreversible loss of cell adhesion and proliferative capacity[1].
β-Estradiol 17-acetate (10 nM; 32 d) restores the viability, adhesion and proliferation capacities of cryopreserved-thawed GM-derived hBMECs, and the adverse effects caused by hormone withdrawal are fully reversed upon re-administration of this substance[1].

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: ≥ 1.88 mg/mL (5.98 mM); Suspended solution
This protocol yields a suspended solution of ≥ 1.88 mg/mL (saturation unknown). Suspended solution can be used for oral and intraperitoneal injection.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (18.8 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: ≥ 1.88 mg/mL (5.98 mM); Clear solution
