ChEBI: Niflumic acid is an aromatic carboxylic acid and a member of pyridines. | [Manufacturing Process]
Niflumic acid is prepared as follows: Nicotinic acid, m-trifluoromethylaniline,
and potassium iodide are intimately mixed and heated on an oil bath at
140°C. The mixture melts to give a dark red liquid. The temperature of the oil
bath is allowed to fall to 100°C and is maintained at this temperature for an
hour and a half. The mixture puffs up and forms a yellow crystalline mass.
After cooling to ordinary temperature, this mass is ground up in a mortar and
extracted several times with small volumes of ether to remove excess mtrifluoromethylaniline. The residue is then washed twice with 10 ml of distilled
water to remove m-trifluoromethylaniline hydrochloride and potassium iodide,
and finally twice with 10 ml of 95% alcohol to remove colored resinous
contaminants. After drying at 100°C, 2-(m-trifluoromethylanilino)nicotinic acid
is obtained as pale yellow needles (from 70% ethanol) melting at 204°C
(Kofler block). | [Therapeutic Function]
Antiinflammatory | [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. | [Synthesis]
Niflumic acid, 2-3-(trifluoromethyl)anilino nicotinic acid (3.2.21), is synthesized either by the reaction of 2-chloronicotinic acid with 3-trifluoromethylaniline
[84¨C86], or 2-aminonicotinic acid with 1-bromo-3-trifluoromethylbenzene [87].
