N-Benzyltryptamine
''N''-Benzyltryptamine, also known as T-NB or NB-T, is a serotonin receptor modulator of the tryptamine family. It is the ''N''-benzyl derivative of tryptamine. The drug shows affinity for the serotonin 5-HT2 receptors. Its affinities (Ki) were 245nM for the serotonin 5-HT2A receptor, 100nM for the serotonin 5-HT2B receptor, and 186nM for the serotonin 5-HT2C receptor. In terms of activational activities, specifically calcium mobilization, ''N''-benzyltryptamine's () values were 162nM (62%) at the serotonin 5-HT2A receptor and 50nM (121%) at the serotonin 5-HT2C receptor. At the serotonin 5-HT2A receptor, it had higher affinity than tryptamine, but lower activational potency in comparison. In other studies, at the rat serotonin 5-HT2A receptor, ''N''-benzyltryptamine's was 407nM and its was 26%. The drug has been reported to produce serotonergic psychedelic-like effects in early studies in animals. This included hyperthermia and behavioral changes in the open field test. ...

25-NB
The 25-NB (25''x''-NB''x'') series, or NBOMe series, also known as the ''N''-benzylphenethylamines, is a family of serotonergic psychedelics. They are substituted phenethylamines and were derived from the 2C family. The most commonly encountered NBOMe drugs are 25I-NBOMe, 25B-NBOMe, and 25C-NBOMe. The NBOMe drugs act as selective agonists of the serotonin 5-HT2 receptors. The 25-NB family is unique relative to other classes of psychedelics in that they are, generally speaking, extremely potent and quite selective for the 5-HT2 receptors. Use of NBOMe series drugs has caused many deaths and hospitalisations since the drugs popularisation in the 2010s. This is primarily due to their high potency, unpredictable pharmacokinetics, and sellers passing off the compounds in the series as LSD. Use The 25-NB drugs are inactive orally and instead are typically used sublingually, buccally, by insufflation, or sometimes via inhalation. They are typically employed at doses in the ra ...

Substituted Tryptamine
Substituted tryptamines, or simply tryptamines, also known as serotonin analogues (i.e., 5-hydroxytryptamine analogues), are organic compounds which may be thought of as being derived from tryptamine itself. The molecular structures of all tryptamines contain an indole ring, joined to an amino group, amino (NH2) group via an ethyl (−CH2–CH2−) side chain, sidechain. In substituted tryptamines, the indole ring, sidechain, and/or amino group are modified by substituting another group for one of the hydrogen (H) atoms. Well-known tryptamines include serotonin, an important neurotransmitter, and melatonin, a hormone involved in regulating the sleep-wake cycle. Tryptamine alkaloids are found in fungi, plants and animals; and sometimes used by humans for the neurological or psychotropic effects of the substance. Prominent examples of tryptamine alkaloids include psilocybin (from "psilocybin mushrooms") and dimethyltryptamine, DMT. In South America, dimethyltryptamine is obtained f ...

5-MeO-T-NBOMe
5-MeO-T-NBOMe, also known as 5MT-NBOMe or NBOMe-5-MeO-T, is a psychedelic of the tryptamine family related to the 25-NB (NBOMe) drugs. It has been sold online as a designer drug. Pharmacology 5-MeO-T-NBOMe is a serotonin 5-HT2 receptor agonist and produces the head-twitch response in rodents. However, compared to 25I-NBOMe, the drug is much less potent in producing the head-twitch response (~10-fold) and produces a much weaker maximal response (~25%). 5-MeO-T-NBOMe is many times less potent than comparable phenethylamines such as 25C-NBOMe, but is still a reasonably potent and effective partial agonist for the 5-HT2 family of serotonin receptors. A number of related compounds have also been developed, and in contrast to the phenethylamine counterparts the ''meta''-substituted benzyl derivatives are in many cases more potent than the ''ortho''-substituted benzyl compounds. History 5-MeO-T-NBOMe was described by David E. Nichols and colleagues in 2015. See also * Substituted t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Serotonin Receptor Modulator
5-HT receptors, 5-hydroxytryptamine receptors, or serotonin receptors, are a group of G protein-coupled receptor and ligand-gated ion channels found in multiple tissues including the central and peripheral nervous systems. They mediate both excitatory and inhibitory neurotransmission. The serotonin (i.e., 5-hydroxytryptamine, hence "5-HT") 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, includin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hyperthermia
Hyperthermia, also known as overheating, is a condition in which an individual's body temperature is elevated beyond normal due to failed thermoregulation. The person's body produces or absorbs more heat than it dissipates. When extreme temperature elevation occurs, it becomes a medical emergency requiring immediate treatment to prevent disability or death. Almost half a million deaths are recorded every year from hyperthermia. The most common causes include heat stroke and adverse reactions to drugs. Heat stroke is an acute temperature elevation caused by exposure to excessive heat, or combination of heat and humidity, that overwhelms the heat-regulating mechanisms of the body. The latter is a relatively rare side effect of many drugs, particularly those that affect the central nervous system. Malignant hyperthermia is a rare complication of some types of general anesthesia. Hyperthermia can also be caused by a traumatic brain injury. Hyperthermia differs from feve ...

5-HT2C Agonists
Serotonin (), also known as 5-hydroxytryptamine (5-HT), is a monoamine neurotransmitter with a wide range of functions in both the central nervous system (CNS) and also peripheral tissues. It is involved in mood, cognition, reward, learning, memory, and physiological processes such as vomiting and vasoconstriction. In the CNS, serotonin regulates mood, appetite, and sleep. Most of the body's serotonin—about 90%—is synthesized in the gastrointestinal tract by enterochromaffin cells, where it regulates intestinal movements. It is also produced in smaller amounts in the brainstem's raphe nuclei, the skin's Merkel cells, pulmonary neuroendocrine cells, and taste receptor cells of the tongue. Once secreted, serotonin is taken up by platelets in the blood, which release it during clotting to promote vasoconstriction and platelet aggregation. Around 8% of the body's serotonin is stored in platelets, and 1–2% is found in the CNS. Serotonin acts as both a vasoconstrictor and v ...

25B-NB
25B-NB, also known as ''N''-benzyl-4-bromo-2,5-dimethoxyphenethylamine (''N''-benzyl-2C-B or NB-2C-B), is a recreational designer drug from the 25-NB subgroup of the substituted phenethylamine family, with psychedelic effects. It has a binding affinity (Ki) of 16 nM at the serotonin receptor 5-HT2A and 90 nM at 5-HT2C and reportedly has a potency in between that of 2C-B and 25B-NBOMe (NBOMe-2C-B). 25B-NB was first synthesized and described by Richard Glennon and colleagues in 1994. It was the first drug of the 25-NB family to be developed. Subsequently, modification of 25B-NB led to the development of the more well-known 25-NB family drugs such as 25I-NBOMe. See also * ''N''-Ethyl-2C-B * 25B-NBF * 25B-NBOH 25B-NBOH (2C-B-NBOH, NBOH-2C-B) is a derivative of the phenethylamine derived hallucinogen 2C-B which has been sold as a designer drug.

Chemical Derivative
In chemistry, a derivative is a compound that is derived from a similar compound by a chemical reaction. In the past, derivative also meant a compound that ''can be imagined to'' arise from another compound, if one atom or group of atoms is replaced with another atom or group of atoms, but modern chemical language now uses the term structural analog for this meaning, thus eliminating ambiguity. The term "structural analogue" is common in organic chemistry. In biochemistry, the word is used for compounds that at least theoretically can be formed from the precursor compound. Chemical derivatives may be used to facilitate analysis. For example, melting point (MP) analysis can assist in identification of many organic compounds. A crystalline derivative may be prepared, such as a semicarbazone or 2,4-dinitrophenylhydrazone (derived from aldehydes or ketones), as a simple way of verifying the identity of the original compound, assuming that a table of derivative MP values is availa ...
