Physical and Chemical Properties | Yellow crystalline powder, soluble in methanol, ethanol, DMSO and other organic solvents, derived from Peganum harma. |
In vitro study | Harmine inhibits tau phosphorylation by DYRK1A by selected DANDYs, with an IC 50 of 190 nM. Harmine negatively regulates homologous recombination (HR) by interfering Rad51 recruitment, resulting in severe cytotoxicity in hepatoma cells. Furthermore, NHEJ inhibitor Nu7441 markedly sensitizes Hep3B cells to the anti-proliferative effects of Harmine. |
In vivo study | It is shown that brain water content is significantly increased in the TBI group. Treatment with Harmine significantly reduces the tissue water content at 1, 3 and 5 days, compared with the TBI group. Harmine treatment significantly reduces the escape latency at 3 and 5 days, compared with the TBI group. Post-TBI administration of Harmine significantly improves the motor function recovery of the rats at 1, 3 and 5 days following TBI, compared with the TBI group without Harmine treatment. The neuronal survival rate in the Harmine-treated group is significantly increased, compared with the TBI group. Administration of Harmine results in marked elevation in the expression of GLT-1, compared with the TBI group. The administration of Harmine significantly reduces the expression of caspase 3, compared with the TBI group. |

biological activity | Harmine (Telepathine) is a fluorescent harmala alkaloid belonging to the β-carboline family of compounds, it is a competitive inhibitor of the ATP binding of the kinase pocket of DYRK1A with high cell permeability, and has an IC50 value about 60-fold higher than that of dyrk2. Harmine can also inhibit monoamine oxides (MAOs) and cdc-like kinases (CLKs). The Ki value for Harmine's inhibition of 5-HT2A serotin receptor was 397 nM. |
