Tryptoline (also known as a tetrahydronorharmane), a metabolite of tryptamine, is an inhibitor of the reuptake of serotonin. Some in vitro experiments have shown that tryptoline prevents the lipid peroxidation induced by hydrogen peroxide and thus this compound can be further investigated as a neuroprotective agent.

Curator's Comment: Tetrahydro-beta-carboline (tryptoline) was more potent inhibitor than its 1-methylderivative, tetrahydroharmane (methtryptoline) or norharmane (beta-carboline) for the serotonin (5-HT) uptake in rat brain synaptosomes.
