General description

Tolfenamic acid is a fenamate and is made up of a monocarboxylate diphenylamine nucleus.

Application

Tolfenamic acid has been used in Arabidopsis bud assay for activity comparison with quinazolinedione derivatives (QADD) based compounds.

Biochem/physiol Actions

Tolfenamic acid is involved in the inhibition of prostaglandin synthesis. It also plays a role in apoptosis of head and neck cancer cells.
Non-steroidal anti-inflammatory agent. Interferes with synthesis of β-amyloid precursor protein, and thus Aβ peptides, by promoting degradation of an essential transcription factor.
