General description

  • Harmane is a potent tremor-producing β-carboline alkaloid and neurotoxin.
  • It is major representative of heterocyclic aromatic amines, a group of mutagenic and carcinogenic substances which are formed in meat from the precursors creatine, creatinine, amino acids and sugars during the heating at high temperatures.
  • Blood harmane concentration is elevated in essential tremor, late-life neurological disease.

Application

  • Harmane was used in trace level determination of harmane by planar chromatography coupled with (tandem) mass spectrometry.
  • It was used to study interactions of norharman and harman with DNA.
  • It may be used as matrix for analysis of cyclodextrins and for sulfated oligosaccharides in combination with DHB as co-matrix.

Biochem/physiol Actions

I1 imidazoline binding site agonist.

Preparation Note

Harmane dissolves in methanol at a concentration of 50mg/ml to form a clear, colourless to yellow solution.

Greater prefrontal cortex and anterior cingulate cortex monoamine oxidase A (MAO-A) binding is associated with depressed mood. Substances in cigarette smoke, such as harman, inhibit MAO-A, and cigarette withdrawal is associated with depressed mood. Dysphoria during cigarette withdrawal predicts relapse.

A new alkaloid, 5-bromo-8-methoxy-1-methyl-beta-carboline (1), has been isolated from the New Zealand marine bryozoan Pterocella Vesiculosa. Structural elucidation was achieved through NMR spectroscopic and mass spectrometric analysis, and a single-crystal X-ray diffraction analysis of 1 was performed. The biological activity
