Mechanisms of tremor induction by harmine

European Journal of Pharmacology, 1974
Abstract Various agents known to modify cerebral serotoninergic, dopaminergic and cholinergic function were used to investigate the possible relationship between these transmitter systems and the induction and modulation of harmine tremor. The results indicate a non-involvement of cerebral cholinergic function and a possible involvement of cerebral ...

Harmine Action in Rats with Lymphostatic Encephalopathy

Pharmacology, 1977
In rats with lymphostatic encephalopathy the duration of harmine tremor was lengthened, and the brain concentrations of harmine decreased more slowly than in sham-operated controls. The tremor began simultaneously in both rat groups at coinciding brain concentrations of harmine.

Untersuchungen zur Biosynthese des Harmins

Archiv der Pharmazie, 1968
AbstractMit Hilfe markierter Vorstufen wurde die Biosynthese des Harmins (I) in Peganum harmala untersucht. Durch Fütterung von Tryptophan‐(β‐14C‐15Nβ) konnte gezeigt werden, das die Seitenkette mit Ausnahme der Carboxylgruppe spezifisch in das β‐Carbolin‐System eingebaut wird. Das gleiche Ergebnis wurde mit Tryptamin‐(β‐14C‐15N) erzielt.

DNA binding properties of 9-substituted harmine derivatives

Biochemical and Biophysical Research Communications, 2005
The beta-carboline alkaloids have been characterized as a group of potential antitumor agents. The underlying mechanisms of harmine and its derivatives were investigated by DNA binding assay and Topoisomerase (Topo) inhibition assay. Meanwhile, the DNA photocleavage potential of these compounds and their cytotoxicity were also examined by DNA ...
