General description

Norharmane is an alkaloid widely present in living organisms and can also be chemically synthesized. It is a β-carboline derivative composed of indole and pyridine.

Application

Norharmane has been used:
  • as a β-carboline to study its effect on nigrostriatal dopamine (DA) neurons
  • as an internal standard in gas chromatography-mass spectrometry (GC-MS) analyses using Conidiobulus coronatus filtrates
  • as a β-carboline-3-carboxylic acid N-methylamide (CMA) analog to study its binding ability with Mcm2-7 (minichromosome maintenance)

Biochem/physiol Actions

Norharmane and its derivative exhibit anti-cancer properties. It acts as a monoamine oxidase (MAO) inhibitor and might benefit Parkinson′s disease (PD). High levels of β-carboline in plasma are found in PD.
Inhibitor of indoleamine 2,3-dioxygenase (IDO).
