A central nervous system stimulant and potent monoamine oxidase inhibitor obtained from Peganum harmala (family Zygophyllaceae) and Banisteria caapi (family Malpighaceae); psychic effects resemble those of LSD, but sedative and depressive qualities may predominate over hallucinatory manifestations.

What's more, when harmine was given in combination with a second drug - normally used to boost bone-growth - 40 times more beta cells formed a day.
Keeping in view the attractive chemistry, pharmacological significance and therapeutic prospective of harmine series of bases - the [beta]-carboline alkaloids, various O-alkyl (2-18) and bromo derivatives (19-20) of harmol (1) have been prepared as a part of programme towards obtaining compounds possessing significant pharmacological activity in the present studies.
The harmaline is a methoxyharmalol and a dihydroharmine; it constitutes 2/3 of the total alkaloids of the seed; it would be twice as toxic as the harmine (Figure 5) [28].
We recently reported that administration of a single oral dose of ayahuasca (dose: 2.2 mL/kg; alkaloid content in the sample: 0.8 mg/mL DMT, 0.21 mg/mL harmine, no harmaline was detected, and THH was not analyzed due to a lack of analytical requirements) in an open-label trial to 17 patients with treatment-resistant major depressive disorder (MDD) was associated with significant decreases in depression symptoms assessed with the Hamilton Rating Scale for Depression (HAM-D) and the Montgomery-Asberg Depression Rating Scale (MADRS) from 80 minutes to day 21 (10,11).
In the aromatic region, vasicine, vasicinone, harmaline, and harmine were identified in the methanol extracts of P.
206) A very recent study published by the Beckley/Sant Pau Research Programme even claims that when two of the more prominent alkaloids found in Ayahuasca, harmine and tetrahydroharmine, were placed into a petri dish with hippocampal brain cells, the cells developed into neurons at a surprisingly rapid rate (Ketler, 2017).
Harmine, tetrahydroharmine and harmaline are potent inhibitors of peripheral type-A monoamine oxidase (MAO-A).
Ayahuasca is a vegetable beverage cooked on fire, a lightly dense liquid for oral administration that is native to the Amazon forest; it contains, at least, two kinds of plants: the Banisteriopsis caapi vine (a source of harmine and harmaline, with a monoamine oxidase inhibiting action -IMAO) and the Psychotria viridis bush (rich in DMT).
The centroid of ligands harmine (HRM) in 2Z5X and 1,4-diphenyl-2-butene (1PB) in 1OJ9 was set as the center of active site.

A small molecule harmine induced the expression of PPAR without affecting the expression of C/EBP[beta] through Wnt signaling pathway [27].
