In Vitro
Tolfenamic Acid (GEA 6414) is a nonsteroidal antiinflammatory agent, selectively inhibits COX-2, with an IC50 of 13.49 μM (3.53 μg/mL) in LPS-treated (COX-2) canine DH82 monocyte/macrophage cells, but shows no effect on COX-1[1].
Tolfenamic Acid (GEA 6414) (100 μM) inhibits >70% of cell viability of BE3, OE33, and SKGT5. Tolfenamic Acid (GEA 6414) also acts as a potent Sp protein inhibitor, decreases Sp1 and Sp4 and suppresses c-Met expression in esophageal cancer cells BE3 and SKGT5[2].
Tolfenamic AcidTolfenamic Acid (GEA 6414) (50 μM) significantly affects gene expression in L3.6pl cells, and downregulates CENPF, KIF20A, LMNB1, MYB, SKP2, CCNE2, and DDIT3[3].

Solvente y solubilidad
In Vitro:
DMSO : ≥ 100 mg/mL (382.12 mM; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
H2O : < 0.1 mg/mL (insoluble)
* "≥" means soluble, but saturation unknown.
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, 2 years; -20°C, 1 year. When stored at -80°C, please use it within 2 years. When stored at -20°C, please use it within 1 year.

In Vivo:
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.
