N-Methylserotonin
''N''-Methylserotonin is a tryptamine alkaloid. Chemically, it is a derivative of serotonin in which a methyl group resides at its alkyl amine. It is also called ''N''ω-methylserotonin (''N''ω-methyl-5-hydroxytryptamine) to distinguish it from tryptamine-derived compounds in which a methyl group is bonded to the nitrogen atom of the indole group. ''N''-Methylserotonin is found in plants, animals, and fungi. These include the plants, '' Actaea racemosa'' (black cohosh) and ''Zanthoxylum piperitum'', the Green and Golden Bell Frog, ''Litoria aurea'', and ''Amanita'' mushrooms. The compound binds to several serotonin receptors, including the 5-HT7 and 5-HT1A receptors, with high affinity ( IC50 ≤ 2 nM) and selectivity, and displays agonist activity; besides its direct interaction with the serotonin receptors, ''N''-methylserotonin also acts as a selective serotonin reuptake inhibitor. Legal Status United States ''N''-Methylserotonin is not scheduled at the federal level ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zanthoxylum Piperitum
''Zanthoxylum piperitum'', also known as Japanese pepper or Japanese prickly-ash is a deciduous aromatic spiny shrub or small tree of the citrus and rue family Rutaceae, native to Japan and Korea. It is called sanshō () in Japan and chopi () in Korea. Both the leaves and fruits (peppercorns) are used as an aromatic and flavoring in these countries. It is closely related to the Chinese Szechuan peppers, which come from plants of the same genus. Names "Japanese pepper" ''Z. piperitum'' is called in Japan, but the corresponding cognate term in Korean, ''sancho'' () refers to a different species, or '' Z. schinifolium'' known as ''inuzanshō'' or "dog sansho" in Japan. In Korea, ''Z. piperitum'' is called ''chopi'' (), with the English common name given as "Korean pepper" by Korean sources. However, in several regional dialects, notably Gyeongsang dialect, it is also called ''sancho'' or ''jepi'' (). "Japanese prickly-ash" has been used as the standard American common name. ...

5-HT7 Agonists
The 5-HT7 receptor is a member of the GPCR superfamily of cell surface receptors and is activated by the neurotransmitter serotonin (5-hydroxytryptamine, 5-HT) The 5-HT7 receptor is coupled to Gs (stimulates the production of the intracellular signaling molecule cAMP) and is expressed in a variety of human tissues, particularly in the brain, the gastrointestinal tract, and in various blood vessels. This receptor has been a drug development target for the treatment of several clinical disorders. The 5-HT7 receptor is encoded by the ''HTR7'' gene, which in humans is transcribed into 3 different splice variants. Function When the 5-HT7 receptor is activated by serotonin, it sets off a cascade of events starting with release of the stimulatory G protein Gs from the GPCR complex. Gs in turn activates adenylate cyclase which increases intracellular levels of the second messenger cAMP. The 5-HT7 receptor plays a role in smooth muscle relaxation within the vasculature and in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tryptamine
Tryptamine is an indolamine metabolite of the essential amino acid, tryptophan. The chemical structure is defined by an indole ─ a fused benzene and pyrrole ring, and a 2-aminoethyl group at the second carbon (third aromatic atom, with the first one being the heterocyclic nitrogen). The structure of tryptamine is a shared feature of certain aminergic neuromodulators including melatonin, serotonin, bufotenin and psychedelic derivatives such as dimethyltryptamine (DMT), psilocybin, psilocin and others. Tryptamine has been shown to activate trace amine-associated receptors expressed in the mammalian brain, and regulates the activity of dopaminergic, serotonergic and glutamatergic systems. In the human gut, symbiotic bacteria convert dietary tryptophan to tryptamine, which activates 5-HT4 receptors and regulates gastrointestinal motility. Multiple tryptamine-derived drugs have been developed to treat migraines, while trace amine-associated receptors are being explored as a ...

Serotonin Receptors
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. They mediate both excitatory and inhibitory neurotransmission. The serotonin receptors are activated by the neurotransmitter serotonin, which acts as their natural ligand. The serotonin receptors modulate the release of many neurotransmitters, including glutamate, GABA, dopamine, epinephrine / norepinephrine, and acetylcholine, as well as many hormones, including oxytocin, prolactin, vasopressin, cortisol, corticotropin, and substance P, among others. Serotonin receptors influence various biological and neurological processes such as aggression, anxiety, appetite, cognition, learning, memory, mood, nausea, sleep, and thermoregulation. They are the target of a variety of pharmaceutical and recreational drugs, including many antidepressants, antipsychotics, anorectics, antiemetics, gast ...

5-HT1A Agonists
The serotonin 1A receptor (or 5-HT1A receptor) is a subtype of serotonin receptor, or 5-HT receptor, that binds serotonin, also known as 5-HT, a neurotransmitter. 5-HT1A is expressed in the brain, spleen, and neonatal kidney. It is a G protein-coupled receptor (GPCR), coupled to the Gi protein, and its activation in the brain mediates hyperpolarisation and reduction of firing rate of the postsynaptic neuron. In humans, the serotonin 1A receptor is encoded by the HTR1A gene. Distribution The 5-HT1A receptor is the most widespread of all the 5-HT receptors. In the central nervous system, 5-HT1A receptors exist in the cerebral cortex, hippocampus, septum, amygdala, and raphe nucleus in high densities, while low amounts also exist in the basal ganglia and thalamus. The 5-HT1A receptors in the raphe nucleus are largely somatodendritic autoreceptors, whereas those in other areas such as the hippocampus are postsynaptic receptors.

Controlled Substance
A controlled substance is generally a drug or chemical whose manufacture, possession and use is regulated by a government, such as illicitly used drugs or prescription medications that are designated by law. Some treaties, notably the Single Convention on Narcotic Drugs, the Convention on Psychotropic Substances, and the United Nations Convention Against Illicit Traffic in Narcotic Drugs and Psychotropic Substances, provide internationally agreed-upon "schedules" of controlled substances, which have been incorporated into national laws; however, national laws usually significantly expand on these international conventions. Some precursor chemicals used for the production of illegal drugs are also controlled substances in many countries, even though they may lack the pharmacological effects of the drugs themselves. Substances are classified according to schedules and consist primarily of potentially psychoactive substances and anabolic steroids. The controlled substances do not ...

Federal Analog Act
The Federal Analogue Act, , is a section of the United States Controlled Substances Act passed in 1986 which allows any chemical "substantially similar" to a controlled substance listed in Controlled Substances Act#Schedule I controlled substances, Schedule I or Controlled Substances Act#Schedule II controlled substances, II to be treated as if it were listed in Schedule I, but only if intended for human consumption. These similar substances are often called designer drugs. The law's constitutionality has been questioned by now Supreme Court Justice Neil Gorsuch; its broad reach has been used to successfully prosecute possession of chemicals openly sold as dietary supplements and naturally contained in foods such as chocolate. Definition (32) *(A) Except as provided in subparagraph (C), the term ''controlled substance analogue'' means a substance - **(i) the chemical structure of which is substantially similar to the chemical structure of a controlled substance in schedule I or I ...

Bufotenin
Bufotenin (5-HO-DMT, bufotenine) is a tryptamine derivative - more specifically, a DMT derivative - related to the neurotransmitter serotonin. It is an alkaloid found in some species of toads (especially the skin), mushrooms and plants. The name bufotenin originates from the toad genus ''Bufo'', which includes several species of psychoactive toads, most notably ''Incilius alvarius'', that secrete bufotoxins from their parotoid glands. Bufotenin is similar in chemical structure to the psychedelics psilocin (4-HO-DMT), 5-MeO-DMT, and DMT, chemicals which also occur in some of the same fungus, plant, and animal species as bufotenin. Nomenclature Bufotenin (bufotenine) is also known by the chemical names 5-hydroxy-''N'',''N''-dimethyltryptamine (5-HO-DMT), ''N'',''N''-dimethyl-5-hydroxytryptamine, dimethyl serotonin, and mappine. History Bufotenin was isolated from toad skin, and named by the Austrian chemist Handovsky at the University of Prague during World War I. The struct ...

Selective Serotonin Reuptake Inhibitor
Selective serotonin reuptake inhibitors (SSRIs) are a class of drugs that are typically used as antidepressants in the treatment of major depressive disorder, anxiety disorders, and other psychological conditions. SSRIs increase the extracellular level of the neurotransmitter serotonin by limiting its reabsorption (reuptake) into the presynaptic cell. They have varying degrees of selectivity for the other monoamine transporters, with pure SSRIs having strong affinity for the serotonin transporter and only weak affinity for the norepinephrine and dopamine transporters. SSRIs are the most widely prescribed antidepressants in many countries. The efficacy of SSRIs in mild or moderate cases of depression has been disputed and may or may not be outweighed by side effects, especially in adolescent populations. Medical uses The main indication for SSRIs is major depressive disorder; however, they are frequently prescribed for anxiety disorders, such as social anxiety disorder, ge ...
