Otenaproxesul (100 μM) inhibits human melanoma cell proliferation by inhibiting pro-survival pathways associated with NF-B and Akt activation[2].
Otenaproxesul (100 μM) induces apoptosis of human melanoma cells[2].
Otenaproxesul (100 M) causes inhibition of IkB degradation and of NF-kB nuclear translocation as demonstrated by a reduction in band intensity of the p65 subunit in A375 cells[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Line:A375 cells.
-
Concentration:100 μM.
-
Incubation Time:24, 48 and 72 h.
-
Result:Caused an inhibition of cell proliferation by 38.2%, 63.2% and 66%, respectively (P < 0.001).
Otenaproxesul (orally, 43 μmol/kg) inhibits growth of melanoma tumors in vivo and reduce plasma levels of melanoma-associated chemokines[2].
Otenaproxesul (orally, 16 mg/kg) results in significant inhibition of bone defect and other histological characteristics (such as flatness of the gingival epithelium, chronic inflammatory cell infiltration and loss of connective tissue in the gingival papillae). Otenaproxesul inhibits the increase of gingival IL-1β and IL-6 secondary to periodontitis, but IL-10 is unaffected[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: ≥ 2.5 mg/mL (6.84 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.
