Minaprine

 ( Acetylcholinesterase Inhibitors ) 

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oxidase inhibitor antidepressant drug that was used in France for the treatment of major depression until it was withdrawn drug from the market in 1996 because it caused .

A study found that it acts as a reversible inhibitor of MAO-A (RIMA) in rats. It has also been found to weakly enzyme inhibitor acetylcholinesterase in rat brain (striatum) homogenates.

It has demonstrated significant antibiotic activity against M. chelonae and M. abscessus in tests with antibiotic resistant bacteria.

Synthesis The first synthesis of minaprine was disclosed in patents published in 1979.

The final step is the reaction between a chloro-substituted pyridazine and the primary amine group of a morpholine derivative. The required pyridazine can be made by the reaction of acetophenone and pyruvic acid, followed by ring formation using hydrazine, giving a pyrazidinone. Treatment of this with phosphoryl chloride converts it to the required chloro derivative.
