Usage And Synthesis

Description

Harmine (343-27-1) is a selective competitive and reversible inhibitor of MAO-A (IC50?= 8 μM).1?Harmine is a potent and specific inhibitor of both the kinase activity and autophosphorylation of tyrosine during translation DYRK1A (IC50‘s: DYRKA1A = 33 nM; DYRKA1B = 166 nM; DYRK2 = 1.9 μM; DYRK4 = 80 μM).2,3?Inhibits self-renewal and promotes differentiation of glioblastoma stem-like cells (GSLC’s) possibly via inhibition of Akt phosphorylation.4?Harmine has also been shown to possess antimicrobial, antifungal, antiplasmodial, antitumor, antioxidant, antimutagenic and antigenotoxic properties.5?Inhibits osteoclast differentiation and bone resorption via downregulation of c-Fos and NFATc1 induced by RANKL.6

Chemical Properties

yellow to slightly green crystalline powder

Uses

Harmine Monohydrochloride is an anti-viral agents for the treatment of EV71 infection. It inhibits enterovirus 71 replication by targeting NF-κB pathway.

in vivo

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^[4].

IC 50

5-HT_2A Receptor: 397 nM (Ki); DYRK1A

Purification Methods

The hydrate crystallises as fluorescent crystals from water. The anhydrous salt has m 319o. [Beilstein 23/12 V 237.]
