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: ≥ 2.08 mg/mL (4.30 mM); Clear solution
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 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: ≥ 2.08 mg/mL (4.30 mM); Clear solution
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 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.

Protocole
Bone marrow (BM) cells are flushed from femurs of BALB/c mice using sterile CM. Freshly harvested (BM) cells (0.5×106) are differentiated in the presence of 20 ng/mL recombinant mouse GM-CSF, ±PGE2 (10 nM), at 37°C, for 8 d. CM C fresh GM-CSF ± PGE2 is changed on days 3 and 6. After in vitro differentiation, cells are analyzed by flow cytometry. For certain experiments, CT26, 4T1 cell supernatants, and/or EP1 (SC-57089), EP2 (ER-880696), EP3 (L-798106), or EP4 (E7046) antagonists at 1 mM, are added to the BM cells. To assess the effect of differentiated BM cells on T cell proliferation, mouse BM cells differentiated are co-cultured for 72 hours with anti-CD3/CD28 Dynabeadsstimulated and CFSE (1 mM)-stained T cells. T cell proliferation is assessed by CFSE dilution using flow cytometry.
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
For the tumor isograft efficacy studies, 6-week old female BALB/c mice are implanted with cancer cells: 1×105 CT26 or 4T1 cells or 8×105 H22 cells per mouse s.c., or 1×105 EMT6 cells in the mammary fat pad. C57BL/6 mice are implanted s.c. with 1×106 Pan02 cells per mouse, and A/J mice are implanted s.c. with 2-3 mm3 SAI/N tumor fragments. To investigate the role of T cells in the anti-tumor response, 6 week old female nude mice (which lack T cells) are injected s.c. with 1×105 CT26 cells. When tumors reach approximately 50-100 mm3, tumor-bearing mice are randomly assigned to vehicle or treatment groups, and treatment regimens begin. E7046 is administered per oral (p.o.) as a 100 or 150 mg/kg suspension in 0.5% MC, daily for 21 d (QDx21). For the combination studies, E7777 is administered intravenously (i.v.) at 2.5 mg/mouse in saline, as 2 to 3 doses injected one week apart (Q7Dx2-3). Tumor volumes and body weights are recorded 2-3 times a week. For comparison with current immunotherapies, in addition to vehicle control and E7046 C E7777 groups, mice are assigned to anti-PD1 antibodies or anti-mouse PD-1 C antimouse CTLA4 antibodies treatment groups. Anti-PD-1 and anti-CTLA-4 antibodies (1 mg/mL), are administered i.p. in 100 mL, 3 times 4 d apart (Q4Dx3) for a total of 300 mg each. Isotype controls are administered i.p. at 1 mg/mL to the control group. For the CD4CT and CD8CT lymphocyte depletion, antimouse CD4 or anti-mouse CD8 antibodies or their isotype controls are administered in 100 mL, i.p. at 2.5 mg/mL every 4 days, for a total of 4 injections per mouse (1 mg).
