MDMA is an empathogenic-entactogenic and serotonergic psychotropic drug used primarily for recreational, though sometimes also therapeutic, purposes.Among users of MDMA, the serotonergic effects of the drug are often of particular interest and concern: After consuming MDMA, serotonin concentrations are greatly reduced in the brain. 5-HTP is necessary for serotonin production and its ...
5-HTP is produced from the amino acid tryptophan through the action of the enzyme tryptophan hydroxylase. Tryptophan hydroxylase is one of the biopterin-dependent aromatic amino acid hydroxylases. Production of 5-HTP is the rate-limiting step in 5-HT (serotonin) synthesis. 5-HTP is normally rapidly converted to 5-HT by amino acid decarboxylase. [1]
The risk factors [110] for treatment resistant depression are: the duration of the episode of depression, severity of the episode, if bipolar, lack of improvement in symptoms within the first couple of treatment weeks, anxious or avoidant and borderline comorbidity and old age. Treatment resistant depression is best handled with a combination ...
The 5-HT 1B receptor as an example of a metabotropic serotonin receptor. Its crystallographic structure in ribbon representation. 5-HT receptors, 5-hydroxytryptamine receptors, or serotonin receptors, are a group of G protein-coupled receptor and ligand-gated ion channels found in the central and peripheral nervous systems.
[1] [2] It is the α-methylated derivative of 5-hydroxytryptophan (5-HTP), while αMS is the α-methylated analogue of serotonin. [1] [2] Along with α-methyltryptophan (α-MTP), α-Me-5-HTP has been suggested for potential therapeutic use in the treatment of conditions thought by some authors to be related to serotonin deficiency, such as ...

5,6-Dihydroxytryptamine (5,6-DHT) is a monoaminergic neurotoxin and tryptamine derivative related to serotonin (5-hydroxytryptamine) and 5,7-dihydroxytryptamine (5,7-DHT). [ 1 ] [ 2 ] [ 3 ] It is a relatively selective serotonergic neurotoxin , but also acts as a dopaminergic and noradrenergic neurotoxin at higher doses.
