Toloxatone is a reversible monoamine oxidase A inhibitor (MAOI) and antidepressant.
Toloxatone is a reversible monoamine oxidase A inhibitor (MAOI) and antidepressant. Toloxatone belongs to the aryloxazolidinones, a relatively new class of reversible monoamine oxidase A inhibitors (MAOI). Studies show that derivatives such as 3-aryloxazolidin-2-one (oxazolidinones), which are regularly used to treat gram positive infections, represent a new class of reversible as well as irreversible inhibitors for MAO-A and MAO-B enzymes that are able to inhibit protein synthesis and also used for neurodegenerative-type pathologies.

Preparation Note

Toloxatone is soluble in DMSO at a concentration that is greater than 10 mg/ml.

Cholinesterase (ChE) and monoamine oxidase (MAO) inhibitors have been attracted as candidate treatments for Alzheimer's disease (AD). Fifteen khellactone-type coumarins from the roots of Peucedanum japonicum Thunberg were tested for acetylcholinesterase (AChE), butyrylcholinesterase (BChE), and MAO inhibitory activities.
