Application

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

Biochem/physiol Actions

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.
Tolfenamic acid is involved in the inhibition of prostaglandin synthesis. It also plays a role in apoptosis of head and neck cancer cells.

General description

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

The nonsteroidal anti-inflammatory drug (NSAID) tolfenamic acid (TA), previously thought to be dimorphic, is demonstrated to have at least five polymorphs. The new forms were uncovered through the emerging screening technique of polymer-induced heteronucleation (PIHn). The presence of conformational changes

Crystallization from solution involves nucleation and growth; growth conditions greatly influence self-association behaviors of solute molecules in these steps, affecting crystal packing of organic molecules. We examined the role of pre-nucleation association to provide insights into the mutual influence between
