5-HT6 agonists

Bufotenin, also known as dimethylserotonin or as '5-hydroxy-N,N-dimethyltryptamine (5-HO-DMT'), is a serotonergic psychedelic of the tryptamine family. It is a derivative of the psychedelic dimethyltryptamine (DMT) and of the neurotransmitter serotonin (5-hydroxytryptamine; 5-HT). The compound is an alkaloid found in some species of mushrooms, plants, and toads. It is also found naturally in the human body in small amounts. Bufotenin, for instance derived from the trees Anadenanthera colubrina and Anadenanthera peregrina, has a long history of entheogenic use as a snuff in South America.

5-MeO-DMT, also known as '5-methoxy-N,N-dimethyltryptamine, as well as O-methylbufotenin or mebufotenin', is an atypical psychedelic drug, entheogen, and alkaloid of the tryptamine and 5-methoxytryptamine families. It is found naturally in a wide variety of plant species, and is also secreted by the glands of at least one toad species, the Colorado River toad (Incilius alvarius, formerly Bufo alvarius). It may occur naturally in humans as well. Like its close relatives dimethyltryptamine (DMT) and bufotenin (5-HO-DMT), it has been used as an entheogen in South America. Slang terms include five

Methylergometrine, also known as methylergonovine and sold under the brand name Methergine, is a medication of the ergoline and lysergamide groups which is used as an oxytocic in obstetrics and as an antimigraine agent in the treatment of migraine headaches. It reportedly produces psychedelic effects similar to those of lysergic acid diethylamide (LSD) at high doses.

Methysergide, sold under the brand names Deseril and Sansert, is a monoaminergic medication which is used in the prevention and treatment of migraine and cluster headaches. It has been withdrawn from the market in the United States and Canada due to safety concerns. The drug has also been found to produce psychedelic effects at high doses. It is taken orally.

5-MeO-DiPT, also known as '5-methoxy-N,N-diisopropyltryptamine and sometimes as foxy methoxy or simply foxy', is an atypical psychedelic drug of the tryptamine and 5-methoxytryptamine families. It has unique and distinct effects from other serotonergic tryptamines, including some stimulant- and entactogen-like effects, robust tactile and sexual enhancement, and only light hallucinogenic effects. The drug is usually taken orally, but may also be used by other routes.

E-6801 is a partial agonist of the 5-HT6 receptor. It enhanced recognition memory and reversed the memory deficits of scopolamine in an object recognition task in a rat model. The mechanism of memory enhancement is due to a combined modulation of cholinergic and glutamatergic neurotransmission.

E-6837 is an orally active, 5-HT6 agonist developed in an attempt to create an anti-obesity medication.

WAY-208466 is a potent and highly selective full agonist of the 5-HT6 receptor. It increases GABA levels in the cerebral cortex and tolerance does not appear to occur to this action upon chronic administration. Animal studies have shown that WAY-208466 produces antidepressant and anxiolytic effects in rodents and it may also be useful in the treatment of obsessive-compulsive disorder.

Pellotine, also known as peyotline or '''N-methylanhalonidine', is a tetrahydroisoquinoline alkaloid found in Lophophora species, in particular L. diffusa. It is the second most common alkaloid found in Lophophora williamsii'' (peyote). Pellotine is slightly sedative, and has been used by Native Americans as a constituent of peyote for sacramental purposes. It was reportedly once marketed for use as a sedative. Pellotine has been sold online.
