Ethoxyquin (EQ) does not block Paclitaxel’s (PTX’s) ability to induce cell death in 4 different breast cancer cell lines. Results demonstrate that only when Hsp90 level is down regulated is neuroprotec-tion provided by Ethoxyquin (EQ) no longer seen[2]. It is found that Ethoxyquin provides neuroprotection with a best efficacy range from 30 to 300 nM. It is interesting to note that higher (μM) concentrations of Ethoxyquin do not provide further neuroprotection and in fact at these higher concentrations Ethoxyquin loses its neuroprotective effects[3].

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: ≥ 3.5 mg/mL (16.11 mM); Clear solution
This protocol yields a clear solution of ≥ 3.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (35.0 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: ≥ 3.5 mg/mL (16.11 mM); Clear solution

Protocol
To evaluate the impact of Ethoxyquin (EQ) on Paclitaxel’s (PTX’s) ability to kill breast cancer cells, conditions for culturing 4 cancer cell lines and measuring the ATP levels are optimized for the 96-well plate format. Briefly, 1,500 cells/well in media are plated in 96-well plates for 24 hours. Constant concentrations of PTX with or without Ethoxyquin are added to the wells for another 24 hours. Cellular ATP levels are measured using kit according tomanufacturer ’s protocol[2].

Briefly, DRGs are harvested from embryonic day 14.5 rats according to standard protocols, then cells are plated onto collagen-coated glass coverslips and allowed to extend neurites for 24 hours in media (Neurobasal medium, 50 mM pencillin-streptomycin (PS), 0.2% FBS, 0.5 mM glutamine, 1×B-27 supplement, 0.2% glucose,10 ng/mL glial cell line-derived neurotrophic factor). Ethoxyquin (EQ) or vehicle control is added to the wells for another 24-hour incubation. DRG cells are fixed with 4% paraformaldehyde and stained with anti-βIII-tubulin antibody to delineate the axons. Axon lengths are measured in multiple fields using a random sampling method[2].

To examine the effect of Ethoxyquin (EQ) on Paclitaxel’s (PTX’s) ability to reduce tumor burden in vivo, a mouse model in which breast cancer cell line SUM-159 (3×106 tumor cells suspended in phosphate-buffered saline in a final volume of 0.15 mL) is injected subcutaneously into adult male nude mice. When the tumor size reaches 5 mm in diameter, the animals are randomly assigned to PTX or PTX with Ethoxyquin groups. Ethoxyquin is given by intraperitoneal administration on a daily basis for 3 weeks. At the end of 3 weeks, animals are euthanized and tumor size and weight are measured (n=5 per group)[2].
