Flufenamic acid is a non-steroidal anti-inflammatory agent, inhibits cyclooxygenase (COX), activates AMPK, and also modulates ion channels, blocking chloride channels and L-type Ca²⁺ channels, modulating non-selective cation channels (NSC), activating K⁺ channels. Flufenamic acid binds to the central pocket of TEAD2 YBD and inhibits both TEAD function and TEAD-YAP-dependent processes, such as cell migration and proliferation.

In Vitro

Flufenamic acid is a non-steroidal anti-inflammatory agent, inhibits cyclooxygenase (COX), and also modulates ion channels, blocking chloride channels and L-type Ca²⁺ channels, modulating non-selective cation channels (NSC), activating K⁺ channels. Flufenamic acid inhibits a wide spectrum of TRP channels, including: C3, C7, M2, M3, M4, M5, M7, M8, V1, V3, and V4 but activates at least two TRP channels (C6 and A1)^[1]. Flufenamic acid induces AMPK activation in T84 cells, and such an effect is via a direct stimulation of calcium/calmodulin-dependent protein kinase kinase beta (CaMKKβ) activity^[2]. Moreover, Flufenamic acid (FFA; 5-50 μM) dose-dependently inhibits cAMP-dependent Cl^- secretion in intact T84 cells, suppresses CFTR-mediated apical I_Cl^-, and blocks the Ca²⁺-dependent Cl^- secretion in a dose-dependent manner with IC₅₀ of appr 10 μM and near complete inhibition at 100 μM in T84 cell monolayers, but shows no effect on Na⁺-K⁺ ATPase or NKCC in T84 cells^[3]. Ufenamat at low concentrations can promote osteogenesis of bone marrow mesenchymal stem cells (mBMMSCs) by co-culture with mouse skin mesenchymal stem cells (mSMSCs) ^[5].

In Vivo

Flufenamic acid (50 mg/kg, i.p.) has anti-inflammatory effect in a mouse model of Vibrio cholerae El Tor variant (EL)-induced diarrhea and significantly abrogates EL-induced intestinal fluid secretion and barrier disruption at 20 mg/kg. Furthermore, Flufenamic acid suppresses NF-κB nuclear translocation and expression of proinflammatory mediators and promotes AMPK phosphorylation in the EL-infected mouse intestine^[2].

Stock Solution Working Solution

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.

Protocol

Cell Assay^[3]

In brief, apical and basolateral chambers are filled symmetrically with Kreb's solutions. Thereafter, DMSO or Flufenamic acid is added into the basolateral chamber followed by apical membrane permealization by amphotericin B. After the amphotericin B-elicited I_sc is stabilized, ouabain is added into the basolateral chamber. The ouabain sensitive I_sc is used as an indicator of Na⁺-K⁺ ATPase activity^[3].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Administration^[2]

Rats^[2]
Six-week-old male ICR outbred mice (weight 30-35 g) are fasted for 24 h before anesthesia using an intraperitoneal injection of nembutal (60 mg/kg). Following abdominal incision, the ileum is ligated (appr 3-4 cm long) and inoculated with 100 µL of PBS or PBS containing V. cholerae (10⁵ CFU/loop) with or without a concomitant intraperitoneal injection of Flufenamic acid or metformin. Twelve hours post-inoculation, ileal loops are removed for weight/length ratio measurement, biochemical analysis and ultrastructural evaluation^[2].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
