4-Hydroxy-5-methoxytryptamine
4-Hydroxy-5-methoxytryptamine is a serotonergic neurotoxin of the tryptamine family. It is structurally related to the monoamine neurotransmitter serotonin. The drug is also a monoamine [reuptake inhibitor]. Its analogue 4,5-dihydroxytryptamine is also a serotonergic neurotoxin. Rapid auto-oxidation of 4-HO-5-MeO-T and 4,5-DHT prevents them from being used as serotonergic neurotoxins in scientific research.
