4C-B
4C-B (also known as 4C-DOB or DOB-B) is a lesser-known psychedelic drug which is related to 2C-B and DOB. It is a reasonably potent 5-HT2A receptor partial agonist with a Ki of 7.6nM, but has relatively low efficacy (15% relative to 5-HT). It is briefly mentioned in Alexander Shulgin's book PiHKAL (Phenethylamines i Have Known And Loved) but was never tested by him, however it has subsequently been tested by other researchers and was found to be active in a dose range of 50-80mg with a duration of around 8 hours, though with generally milder effects than 2C-B or DOB.

2,5-Dimethoxy-4-bromoamphetamine
Dimethoxybromoamphetamine (DOB), also known as brolamfetamine (INN) and bromo-DMA, is a psychedelic drug and substituted amphetamine of the phenethylamine class of compounds. DOB was first synthesized by Alexander Shulgin in 1967. Its synthesis and effects are documented in Shulgin's book '' PiHKAL: A Chemical Love Story''. Chemistry The full name of the chemical is 2,5-dimethoxy-4-bromoamphetamine. DOB has a stereocenter and ''R''-(–)-DOB is the eutomer. This is an important finding as it is suggestive that it is targeting different receptors relative to most other phenethylamines (e.g. MDMA) where the ''R''-isomer serves as the distomer. The toxicity of DOB is not fully known, although high doses may cause serious vasoconstriction of the extremities. DOB is one of the most potent compounds in PiHKAL; while the active dose is similar to that of DOI, another psychedelic amphetamine, DOB has been shown to have a higher efficacy in triggering downstream effects mediated by 5-HT2 ...

4C-T-2
2,5-Dimethoxy-4-ethylthio-α-ethylphenethylamine (4C-T-2) is a synthetic drug of the phenethylamine chemical class. It is the α- ethylated analogue of 2C-T-2. Pharmacology Binding profile 4C-T-2 has affinity (Ki) for the 5-HT1A (5,339 nM), 5-HT1E (9,879 nM), 5-HT2A (274.1 nM), 5-HT2B (58.1 nM), 5-HT2C (468.6 nM), 5-HT5A (1,587 nM), 5-HT7 (3,829), D3 (1,273 nM), β2-adrenergic (124.9 nM), I1 (946.5 nM), and σ1 (514 nM) receptors. The activity of 4C-T-2 at these sites has not been assayed, with the exception of the 5-HT2A and 5-HT2C receptors where it acts as a partial agonist.

Ariadne (psychedelic)
Ariadne (also known as 4C-D, 4C-DOM, α-Et-2C-D, BL-3912, or dimoxamine) is a lesser-known psychedelic drug. It is a homologue of 2C-D and DOM. Ariadne was first synthesized by Alexander Shulgin. In his book '' PiHKAL'', Shulgin reported testing Ariadne up to a dose of 32 mg, and reported that it produces psychedelia at a bare threshold. Very little data exists about the pharmacological properties, metabolism, and toxicity of Ariadne in humans apart from Shulgin's limited testing. Shulgin reported that the drug was tested by Bristol Laboratories as an antidepressant, in an anecdote where he was explaining how human testing is invaluable (compared to animal testing) on drugs that change the state of the mind. He said, "Before they launched into a full multi-clinic study to determine if it's going to be worth the animal studies or not, every person on the board of directors took it." In an animal study, Ariadne was shown to produce stimulus generalization in rats trained ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ZC-B
ZC-B (3-(4-bromo-2,5-dimethoxyphenyl)azetidine) is a phenethylamine derivative which acts as a serotonin receptor agonist selective for the 5-HT2 subtypes, with an EC50 of 1.6nM at 5-HT2A, vs 5.8nM at 5-HT2C. It is related to psychedelic phenethylamine derivatives such as 2C-B, but with the ethylamine side chain replaced by an azetidine ring.

Psychedelics, Dissociatives And Deliriants
Hallucinogens are a large, diverse class of psychoactive drugs that can produce altered states of consciousness characterized by major alterations in thought, mood, and perception as well as other changes. Most hallucinogens can be categorized as either being psychedelics, dissociatives, or deliriants. However, certain hallucinogens such as Fly agaric as well as other gabaergic hallucinogenics are more often considered to technically be hypnotics, therefore indicating another separate subcategory of drugs which can substantially alter visual perception. Etymology The word ''hallucinogen'' is derived from the word ''hallucination''. The term ''hallucinate'' dates back to around 1595–1605, and is derived from the Latin ''hallūcinātus'', the past participle of ''(h)allūcināri'', meaning "to wander in the mind." Characteristics Leo Hollister gave five criteria for classifying a drug as hallucinogenic.Glennon RA. Classical drugs: an introductory overview. In Lin GC and Gle ...

2C-B
2C-B (4-Bromo-2,5-dimethoxyphenethylamine) is a psychedelic drug of the 2C family. It was first synthesized by Alexander Shulgin in 1974. In Shulgin's book '' PiHKAL'', the dosage range is listed as 12–24 mg. As a recreational drug, 2C-B is sold as a white powder sometimes pressed in tablets or gel caps. It is also referred to by a number of street names. The drug is usually taken orally, but can also be insufflated or vaporized. While being primarily a psychedelic it is also a mild entactogen. History 2C-B was synthesized from 2,5-dimethoxybenzaldehyde by Alexander Shulgin in 1974. It first saw use among the psychiatric community as an aid during therapy. 2C-B was first sold commercially as a purported aphrodisiac under the trade name "Erox", which was manufactured by the German pharmaceutical company Drittewelle. For several years, it was available as tablets in Dutch smart shops under the name "Nexus" and "B-Dub". Patterns of use 2C-B first became popularized in the ...

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.

Partial Agonist
In pharmacology, partial agonists are drugs that bind to and activate a given receptor, but have only partial efficacy at the receptor relative to a full agonist. They may also be considered ligands which display both agonistic and antagonistic effects—when both a full agonist and partial agonist are present, the partial agonist actually acts as a competitive antagonist , competing with the full agonist for receptor occupancy and producing a net decrease in the receptor activation observed with the full agonist alone. Clinically, partial agonists can be used to activate receptors to give a desired submaximal response when inadequate amounts of the endogenous ligand are present, or they can reduce the overstimulation of receptors when excess amounts of the endogenous ligand are present. Some currently common drugs that have been classed as partial agonists at particular receptors include buspirone, aripiprazole, buprenorphine, nalmefene and norclozapine. Examples of ligands acti ...

Alexander Shulgin
Alexander Theodore "Sasha" Shulgin (June 17, 1925 – June 2, 2014) was an American medicinal chemist, biochemist, organic chemist, pharmacologist, psychopharmacologist, and author. He is credited with introducing 3,4-methylenedioxymethamphetamine (MDMA, commonly known as "ecstasy") to psychologists in the late 1970s for psychopharmaceutical use and for the discovery, synthesis and personal bioassay of over 230 psychoactive compounds for their psychedelic and entactogenic potential. In 1991 and 1997, he and his wife Ann Shulgin compiled the books '' PiHKAL'' and ''TiHKAL'' (standing for ''Phenethylamines'' and ''Tryptamines I Have Known And Loved''), from notebooks that extensively described their work and personal experiences with these two classes of psychoactive drugs. Shulgin performed seminal work into the descriptive synthesis of many of these compounds. Some of Shulgin's noteworthy discoveries include compounds of the 2C* family (such as 2C-B) and compounds of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phenethylamine
Phenethylamine (PEA) is an organic compound, natural monoamine alkaloid, and trace amine, which acts as a central nervous system stimulant in humans. In the brain, phenethylamine regulates monoamine neurotransmission by binding to trace amine-associated receptor 1 (TAAR1) and inhibiting vesicular monoamine transporter 2 (VMAT2) in monoamine neurons. To a lesser extent, it also acts as a neurotransmitter in the human central nervous system. In mammals, phenethylamine is produced from the amino acid L-phenylalanine by the enzyme aromatic L-amino acid decarboxylase via enzymatic decarboxylation. In addition to its presence in mammals, phenethylamine is found in many other organisms and foods, such as chocolate, especially after microbial fermentation. Phenethylamine is sold as a dietary supplement for purported mood and weight loss-related therapeutic benefits; however, in orally ingested phenethylamine, a significant amount is metabolized in the small intestine by monoami ...

Substituted Amphetamines
Substituted amphetamines are a class of compounds based upon the amphetamine structure; it includes all derivative compounds which are formed by replacing, or substituting, one or more hydrogen atoms in the amphetamine core structure with substituents. The compounds in this class span a variety of pharmacological subclasses, including stimulants, empathogens, and hallucinogens, among others. Examples of substituted amphetamines are amphetamine (itself), methamphetamine, ephedrine, cathinone, phentermine, mephentermine, bupropion, methoxyphenamine, selegiline, amfepramone (diethylpropion), pyrovalerone, MDMA (ecstasy), and DOM (STP). Some of amphetamine's substituted derivatives occur in nature, for example in the leaves of ''Ephedra'' and khat plants. Amphetamine was first produced at the end of the 19th century. By the 1930s, amphetamine and some of its derivative compounds found use as decongestants in the symptomatic treatment of colds and also occasionally as psychoac ...
