Biological Activity
Ki: 27.4 nM (ERα), 15.4 nM (ERβ)[1]
(R)-Equol is an agonist of both ERα and ERβ with Kis of 27.4 and 15.4 nM, respectively[1]. (R)-Equol induces a dose-dependent inhibitory effect on the invasive capacity of MDA-MB-231 cells that is significant at the highest concentration tested (50 μM). Following 48-h exposure to (R)-Equol, invasion is reduced by 62% (p=0.009, versus untreated cells) with 50 μM (R)-Equol. Matrix metalloproteinase-2 (MMP-2) expression is significantly down-regulated following treatment with 50 μM (R)-Equol (p=0.035)[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: 50% PEG400 50% Saline
Solubility: 10 mg/mL (41.28 mM); Clear solution; Need ultrasonic
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (10.32 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 (10.32 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.

Working solution concentration: 0.22 mg/mL
Method for preparing stock solution: mg drug dissolved in μL DMSO. Stock solution concentration: mg/mL.
1. Take μL DMSO stock solution;
2. Add μL .
μL , mix evenly;
3. Then add μL Tween 80, mix evenly;
4. Then add μL
Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
Protocol
Cell viability is determined using the well-established MTT assay. Cells are seeded (1.25×105 cells/mL) in 96-well plates in experimental medium (100 μL/well) and incubated for 48 h at 37°C in a 95 % air/5 % CO2 humidified atmosphere. Medium is then replaced with fresh medium containing (R)-Equol (R-equol) (2.5, 10 or 50 μM) or DMSO only as a control. Following 48-h incubation, cell viability is assessed[2].

To investigate the chemopreventive effects of dietary (R)-Equol against chemically induced mammary cancer, female Sprague-Dawley rats bred in-house are fed a soy-free AIN-93G diet from birth to 35 days of age, then separated into different groups. Group 1 (Control group, n=40) continues on this diet, whereas the other group of animals are fed the AIN-93G diet supplemented with 250 mg/kg of (R)-Equol (Group 3, n=41) beginning on day 35 until killing on day 190[3].
