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]
[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 ...
All 5-HT 1D receptors are coupled to inhibition of adenylate cyclase. 5-HT 1B and 5-HT 1D receptors have been difficult to distinguish on a pharmacological basis. After cloning two distinct genes for 5-HT 1B and 5-HT 1D receptors, a better insight into distribution and expression in different tissues was gained, except in brain tissue where ...
Serotonin (/ ˌ s ɛr ə ˈ t oʊ n ɪ n, ˌ s ɪər ə-/) [6] [7] [8] or 5-hydroxytryptamine (5-HT) is a monoamine neurotransmitter.Its biological function is complex, touching on diverse functions including mood, cognition, reward, learning, memory, and numerous physiological processes such as vomiting and vasoconstriction.
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.

5-Hydroxyindoleacetaldehyde (5-HIAL), also known as 5-hydroxytryptaldehyde or as serotonin aldehyde, is an inactive metabolite and metabolic intermediate of the monoamine neurotransmitter serotonin (5-hydroxytryptamine; 5-HT). [2] [3] [1] 5-HIAL is formed from serotonin by oxidative deamination via monoamine oxidase (MAO).
