Application

Niflumic acid has been used:
  • as a chloride channel blocker in mouse olfactory epithelium for odor-induced electroolfactograms (EOGs) measurements, to test its analgesic effect on rat dorsal root ganglion neurons post γ-aminobutyric acid induction
  • as a calcium-activated chloride channel (CaCC) inhibitor in C2C12 myoblasts and also to test its effect on volume-regulated anion channel (VRAC)
  • as an inhibitor of voltage-dependent potassium channel in human embryonic kidney (HEK 293) phoenix cells

Biochem/physiol Actions

Niflumic acid (NFA), a γ-aminobutyric acid type A receptor (GABAARs) antagonist is a non-steroidal anti-inflammatory drug (NSAID) and it belongs to the fenamate class. It is also a blocker of chloride ion channel and a calcium-activated chloride channel (CaCC) inhibitor. NFA possesses anti-inflammatory property and is useful in treating rheumatic disorders. It is also an inhibitor of N-methyl-D-aspartate receptor and glycine receptor. NFA also inhibits enzymes associated with the prostaglandins synthesis.
Selective cyclooxygenase-2 (COX-2) inhibitor.
