Flufenamic acid is a non-steroidal anti-inflammatory agent, inhibits cyclooxygenase (COX), and also modulates ion channels, blocking chloride channels and L-type Ca 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). 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. Moreover, Flufenamic acid (FFA; 5-50 μM) dose-dependently inhibits cAMP-dependent Cl secretion in intact T84 cells, suppresses CFTR-mediated apical ICl, and blocks the Ca-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.
