Metabolite Identification
Common NameMinaprine
DescriptionMinaprine, also known as minaprinum or cantor, belongs to the class of organic compounds known as phenylpyridazines. These are organic compounds containing a pyridazine ring substituted by a phenyl group. A study found that it acts as a reversible inhibitor of MAO-A (RIMA) in rats. Minaprine is a drug which is used for the treatment of depression. Minaprine is a very strong basic compound (based on its pKa). Minaprine is a potentially toxic compound. In a study it has also been found to weakly inhibit acetylcholinesterase in rat brain (striatum) homogenates. 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a monoamine oxidase inhibitor antidepressant drug that was used in France for the treatment of depression until it was withdrawn from the market in 1996 because it caused convulsions.

Transporters

General function:
Involved in neurotransmitter:sodium symporter activity
Specific function:
Serotonin transporter whose primary function in the central nervous system involves the regulation of serotonergic signaling via transport of serotonin molecules from the synaptic cleft back into the pre-synaptic terminal for re-utilization. Plays a key role in mediating regulation of the availability of serotonin to other receptors of serotonergic systems. Terminates the action of serotonin and recycles it in a sodium-dependent manner.
