Biological Activity
20-HEDE (WIT 002)[1].
ω-hydroxylation activity toward arachidonic acid is high in A549 cells, thus, A549 cells are treated with HET0016 or WIT 002 in the invasion assays, and both of them significantly decrease invasion[2]. WIT 002 inhibits proliferation of 786-O and 769-P renal adenocarcinoma cells, but HET0016 and WIT 002 fail to inhibit proliferation of normal renal epithelial cells RPTC[2][3].

Solvent & Solubility
DMSO : 100 mg/mL (308.17 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month. When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

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 (7.70 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 (7.70 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.

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
Human NSCLC cell lines (e.g A549) are seeded onto the upper well of the chamber. Subsequently, serum-free medium with HET0016 (10 μM), WIT002 (10 μM), WIT003 (0.01, 0.1, 1 μM), or ethanol as a control is added to the upper chamber, while the lower well is filled to the top (500 μL) with RPMI-1640 containing 5% fetal calf serum (FCS) as a chemoattractant. Cells are allowed to migrate for 5 h. Cells that have invaded to the bottom surface of the filter are counted with an ocular micrometer in a blinded manner, counting a minimum of 10 high-powered fields (HPF) [2]. Human renal cell adenocarcinoma lines (RPTC) 786-O or 769-P cells are plated and next day (0 hrs) transferred to serum-free medium containing either EGF or ET-1. Cells are exposed either to 10 μM WIT002 or vehicle. Cell counting is performed at the day of transfer to serum free medium (0 hrs) and 24, 48 and 72 hrs thereafter. Medium is changed to fresh containing mitogens and drugs every 24 hrs. Data presented are characteristic experiment from at least two separate experiments, each performed in triplicate[3].

Mice[3]
Experiments are carried out on 6-week immunodefficient athymic nude mice weighing 20-26 g. Animals are acclimated for 1 week prior to injection with renal cell carcinoma. Immediately before each implantation, the cells are trypsinized, counted and resuspended in 10% serum containing RPMI media. The concentration of cells is adjusted to 40 millions/mL and 4 million cells/animal are injected subcutaneously. The cells are allowed to grow for 7-15 days until the size of the tumors reach approximately 0.1 cm3. The mice then receive daily subcutaneous injection (s.c.) injections of WIT 002 (10 mg/kg/day in 200 μL) in an isotonic NaPO4 buffer (pH 9.0) or vehicle (0.1 M NaPO4 solution pH 9.0). The diameter of the tumor is measured on every 3-4 days for 2 weeks using precision calibers. At the end of the experiment the mice are euthanized with CO2 and the tumors were excised to confirm the diameter measurements[3].
