TCB-2
TCB-2 is a hallucinogen discovered in 2006 by Thomas McLean working in the lab of David Nichols at Purdue University. It is a conformationally-restricted derivative of the phenethylamine 2C-B, also a hallucinogen, and acts as a potent agonist for the 5-HT2A and 5-HT2C receptors with a Ki of 0.26 nM at the human 5-HT2A receptor. In drug-substitution experiments in rats, TCB-2 was found to be of similar potency to both LSD and Bromo-DragonFLY, ranking it among the most potent phenethylamine hallucinogens yet discovered. This high potency and selectivity has made TCB-2 useful for distinguishing 5-HT2A mediated responses from those produced by other similar receptors. TCB-2 has similar but not identical effects in animals to related phenethylamine hallucinogens such as DOI, and has been used for studying how the function of the 5-HT2A receptor differs from that of other serotonin receptors in a number of animal models, such as studies of cocaine addiction and neuropathic pain. ...

2CBCB-NBOMe
2CBCB-NBOMe (NBOMe-TCB-2) is a compound indirectly derived from the phenethylamine series of hallucinogens, which was discovered in 2007 at Purdue University as part of the ongoing research program of the team led by David Nichols focusing on the mapping of the specific amino acid residues responsible for ligand binding to the 5HT2A receptor. 2CBCB-NBOMe acts as a potent and selective agonist for the 5-HT2A and 5-HT2C receptors, with a Ki of 0.27 nM at the human 5-HT2A receptor, a similar potency to other agonists such as TCB-2 TCB-2 is a hallucinogen discovered in 2006 by Thomas McLean working in the lab of David Nichols at Purdue University.

2,5-Dimethoxy-4-iodoamphetamine
2,5-Dimethoxy-4-iodoamphetamine (DOI) is a psychedelic drug and a substituted amphetamine. Unlike many other substituted amphetamines, however, it is not primarily a stimulant. DOI has a stereocenter In stereochemistry, a stereocenter of a molecule is an atom (center), axis or plane that is the focus of stereoisomerism; that is, when having at least three different groups bound to the stereocenter, interchanging any two different groups cr ... and ''R''-(−)-DOI is the more active stereoisomer. In neuroscience research, 125I, [125I]-''R''-(−)-DOI is used as a radioligand and indicator of the presence of 5-HT2A receptor, 5-HT2A serotonin receptors. DOI's effects have been compared to LSD, although there are differences that experienced users can distinguish. Besides the longer duration, the trip tends to be more energetic than an LSD trip, with more body load and a different subjective visual experience. The after effects include residual stimulation and difficulty sleepin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jimscaline
Jimscaline (C-(4,5,6-trimethoxyindan-1-yl)methanamine) is a conformationally-restricted derivative of the cactus-derived hallucinogen mescaline, which was discovered in 2006 by a team at Purdue University led by David E. Nichols. It acts as a potent agonist for the 5-HT2A and 5-HT2C receptors with the more active (''R'')-enantiomer having a Ki of 69 nM at the human 5-HT2A receptor, and around three times the potency of mescaline in drug-substitution experiments in animals. This discovery that the side chain of the phenethylamine hallucinogens could be constrained to give chiral ligands with increased activity then led to the later development of the super-potent benzocyclobutene derivative TCB-2.

5-HT2A Receptor
The 5-HT2A receptor is a subtype of the 5-HT2 receptor that belongs to the serotonin receptor family and is a G protein-coupled receptor (GPCR). The 5-HT2A receptor is a cell surface receptor, but has several intracellular locations. 5-HT is short for 5-hydroxy-tryptamine or serotonin. This is the main excitatory receptor subtype among the GPCRs for serotonin, although 5-HT2A may also have an inhibitory effect on certain areas such as the visual cortex and the orbitofrontal cortex. This receptor was first noted for its importance as a target of serotonergic psychedelic drugs such as LSD and psilocybin mushrooms. Later it came back to prominence because it was also found to be mediating, at least partly, the action of many antipsychotic drugs, especially the atypical ones. Downregulation of post-synaptic 5-HT2A receptor is an adaptive process provoked by chronic administration of selective serotonin reuptake inhibitors (SSRIs) and atypical antipsychotics.

2CB-Ind
2CB-Ind is a conformationally-restricted derivative of the phenethylamine hallucinogen 2C-B, discovered in 1974 by Alexander Shulgin. It acts as a moderately potent and selective agonist for the 5-HT2A and 5-HT2C receptors, but unlike the corresponding benzocyclobutene derivative TCB-2 which is considerably more potent than the parent compound 2C-B, 2CB-Ind is several times weaker, with racemic 2CB-Ind having a Ki of 47nM at the human 5-HT2A receptor, only slightly more potent than the mescaline analogue (R)- jimscaline.

Serotonin
Serotonin () or 5-hydroxytryptamine (5-HT) is a monoamine neurotransmitter. Its biological function is complex and multifaceted, modulating mood, cognition, reward, learning, memory, and numerous physiological processes such as vomiting and vasoconstriction. Approximately 90% of the serotonin that the body produces is in the intestinal tract. Biochemically, the indoleamine molecule derives from the amino acid tryptophan, via the (rate-limiting) Tryptophan hydroxylase, hydroxylation of the 5 position on the ring (forming the intermediate 5-Hydroxytryptophan, 5-hydroxytryptophan), and then Aromatic L-amino acid decarboxylase, decarboxylation to produce serotonin. Serotonin is primarily found in the enteric nervous system located in the human gastrointestinal tract, gastrointestinal tract (GI tract). However, it is also produced in the central nervous system (CNS), specifically in the raphe nuclei located in the brainstem, Merkel cells located in the skin, Neuroendocrine cell#Pulmo ...

Phenol Ethers
Phenol (also called carbolic acid) is an aromatic organic compound with the molecular formula . It is a white crystalline solid that is volatile. The molecule consists of a phenyl group () bonded to a hydroxy group (). Mildly acidic, it requires careful handling because it can cause chemical burns. Phenol was first extracted from coal tar, but today is produced on a large scale (about 7 billion kg/year) from petroleum-derived feedstocks. It is an important industrial commodity as a precursor to many materials and useful compounds. It is primarily used to synthesize plastics and related materials. Phenol and its chemical derivatives are essential for production of polycarbonates, epoxies, Bakelite, nylon, detergents, herbicides such as phenoxy herbicides, and numerous pharmaceutical drugs. Properties Phenol is an organic compound appreciably soluble in water, with about 84.2 g dissolving in 1000 mL (0.895 M). Homogeneous mixtures of phenol and wat ...

Psychedelic Phenethylamines
Psychedelics are a subclass of hallucinogenic drugs whose primary effect is to trigger non-ordinary states of consciousness (known as psychedelic experiences or "trips").Pollan, Michael (2018). ''How to Change Your Mind: What the New Science of Psychedelics Teaches Us About Consciousness, Dying, Addiction, Depression, and Transcendence'' Sometimes, they are called classic hallucinogens, serotonergic hallucinogens, or serotonergic psychedelics, and the term ''psychedelics'' is used more broadly to include all hallucinogens; this article uses the narrower definition of ''psychedelics''. Psychedelics cause specific psychological, visual, and auditory changes, and often a substantially altered state of consciousness.Leary, Timothy; Metzner, Ralph (1964). ''The Psychedelic Experience: A Manual Based on The Tibetan Book of the Dead'' Psychedelic states are often compared to meditative, psychodynamic or transcendental types of alterations of mind.

S33005
S33005 is a serotonin–norepinephrine reuptake inhibitor (SNRI) that was under development by Servier for the treatment of depression and related disorders. It is structurally related to venlafaxine but has a more complex molecular structure. Venlafaxine appears to be a sigma modulator, but it is not known if S33005 shares this activity. Synthesis "The 1-cyano-benzocyclobutenes used as starting material are obtained, for example, by subjecting a β- rthohalogeno-phenyl propionitrile to intramolecular condensation in the presence of potassium amide, or by brominating a benzocyclobutene in position 1 with ''N''-bromosuccinimide, followed by exchange of the bromine atom for a cyano group by means of sodium cyanide."
