Minaprine (INN, USAN, BAN) (brand names Brantur, Cantor) is a monoamine oxidase inhibitor antidepressant drug that was used in France for the treatment of depression until it was withdrawn from the market in 1996 because it caused convulsions.[1]

A study found that it acts as a reversible inhibitor of MAO-A (RIMA) in rats.[2] In a study it has also been found to weakly inhibit acetylcholinesterase in rat brain (striatum) homogenates.[3]
