Indoprofen is a nonsteroidal anti-inflammatory drug (NSAID). It was withdrawn worldwide in the 1980s after postmarketing reports of severe gastrointestinal bleeding.[1]

A 2004 study using high-throughput screening found indoprofen to increase production of the survival of motor neuron protein, suggesting it may provide insight into treatments for spinal muscular atrophies.[1][2]

Synthesis

[edit | edit source]

The isoindolone ring system forms the nucleus for this profen NSAID.

The nitro group in 2-(4-nitrophenyl)propionic acid (1) is reduced using iron and hydrochloric acid to give 2-(4-aminophenyl)propionic acid (2). Reaction with phthalic anhydride then gives the phthalimide (4). Treatment with zinc in acetic acid yields indoprofen after reduction of one of the amide groups.[3][4][5]
