?
LY255283 (10 μM, 7 days) significantly suppresses the invasiveness of highly aggressive 253 J-BV bladder cancer cells[4].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Cell Line:253 J-BV cells.
-
Concentration:5 or 10 μM.
-
Incubation Time:7 days.
-
Result:Inhibition of BLT2 signaling attenuates aggressive migration by 253 J-BV cells.
? LY255283 (2.5 mg/kg, ip) inhibits transitional cell carcinoma metastasis in mice models. The result suggests that a BLT2–Nox–ROS–NF–κB cascade plays a critical role in bladder cancer invasion and metastasis[4].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Animal Model:Mice (253 J-BV cells injected)[4].
-
Dosage:2.5 mg/kg.
-
Administration:IP injected 3 and 5 days after injection of cells.
-
Result:By 12 weeks after injection, in mice treated with LY255283 only 0-3 nodules formed per lung, and histological analysis confirmed that the number of micrometastatic lesions was markedly reduced.

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 (6.94 mM); Suspended solution; Need ultrasonic
This protocol yields a suspended solution of 2.5 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.
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 (6.94 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.
