Fenamic acid
Based on 1 Customer Validation
Fenamic acid (N-Phenylanthranilic acid, NPAA) is an orally active chloride channel blocker. Fenamic acid is the basic constituent of non-steroidal anti-inflammatory agents (NSAIA), and derives into mefenamic, tofenacin, flufenac acid and melofenac acid. Fenamic acid also acts as antibacterial and analgesic agent-.

Biological Activity
Chloride Channel[1]
Fenamic acid (N-Phenylanthranilic acid, NPAA) (2.5 mM; 3 h) inhibits Cl- transportation and blocks 36C1- uptake and efflux in endothelial cells[1][2].
Fenamic acid exhibits selectivity to AKR1B10 (the tumor-marker) over human AR, and inhibits AKR1B10 with IC50s of 0.76 μM (Flufenamic acid), 1.6 μM (Mefenamic acid), 9.89 μM (Meclofenamic acid), respectively[4].
Fenamic acid (4-16 μg/mL; 72 h) inhibits 50% of Neisseria gonorrhoeae with an MIC50 value from 4 to 16 μg/mL (tolfenamic acid, flufenamic acid, and meclofenamic acid) in a low frequency of resistance[5].
Fenamic acid (2-8 μg/mL; 8 h) reduces the expression of the porinflammatory cytokines (IL-8, IL-6 and IL-?) by infected endocervical cells without (>128 μg/mL; 24 h) inhibition towards commensal Lactobacillus spp. belonging healthy female genital microbiota[5].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Fenamic acid (N-Phenylanthranilic acid, NPAA) (350-700 mg/kg/day; o.p.; 4 d, 8 d, and 15 d) causes renal papillary necrosis and increases urinary renal papillary antigen-1 (RPA-1) in rats[3].
Fenamic acid (20 g/0.2 mL; i.p.) shows inhibitory effect against the abdominal constriction induced by acetic acid in mice[6].

-
Animal Model:Male Wistar Hannover rats (8-10 weeks old; weighting 220-270 g)[3]
-
Dosage:50, 350, or up to 700 mg/kg
-
Administration:Oral gavage; once daily; 7 days or 14 days
-
Result:Increased absolute paired kidney weights (13.8% at 350 mg/kg and 21.2% at 700/500 mg/kg) and relative to body weight (10.5% at 350 mg/kg/day and 20.3% at 700/500 mg/kg/day).
Caused minimal papillary necrosis of tip with necrosis, hemorrhage, and inflammation of collecting ducts.
-
Animal Model:Male NMRI mice (weighting 20-25 g); abdominal constriction model (writhing test), induced by acetic acid[6]
-
Dosage:100 g/mL, each mice injected with 20 mL
-
Administration:Intraperitoneal injection; once
-
Result:Showed anti-nociceptive activity and inhibited the abdominal constriction with the maximal inhibition of 96.3% (Mefenamic acid).

Solvent & Solubility
DMSO : 125 mg/mL (586.20 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
H2O : < 0.1 mg/mL (insoluble)
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 (protect from light). 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: ≥ 4.17 mg/mL (19.56 mM); Clear solution
This protocol yields a clear solution of ≥ 4.17 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (41.7 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.
