Summary
Norharmane (Norharman), a β-carboline alkaloid, is a potent and reversible monoamine oxidase inhibitor, with IC 50 values of 6.5 and 4.7 μM for MAO-A and MAO-B , respectively. Norharmane causes antidepressant responses. Norharmane is also a prospective anti-cancer photosensitizer. Norharmane alters polar auxin transport (PAT) by inhibiting PIN2, PIN3 and PIN7 transport proteins, thus causing a significant inhibitory effect on the growth of Arabidopsis thaliana seedlings [1] [2] [3] [4] [5] [6] .

In Vitro
Norharmane attenuates quinolinic acid formation by interferon-gamma-stimulated monocytes THP-1 cells and attenuates L-kynurenine formation, with IC
50
values of 51 μM and 43 μM, respectively

In Vivo
Norharmane (0-10 mg/kg, IP, once) shows an anxiety- and antidepressant-like behavior, and decreased locomotor activity [3] .
