4-methyl-2,5-dimethoxyamphetamine
2,5-Dimethoxy-4-methylamphetamine (DOM; known as STP, standing for "Serenity, Tranquility and Peace") is a psychedelic and a substituted amphetamine. It was first synthesized by Alexander Shulgin, and later reported in his book '' PiHKAL: A Chemical Love Story''. DOM is classified as a Schedule I substance in the United States, and is similarly controlled in other parts of the world. Internationally, it is a Schedule I drug under the Convention on Psychotropic Substances. It is generally taken orally. History STP was first synthesized and tested in 1963 by Alexander Shulgin, who was investigating the effect of 4-position substitutions on psychedelic amphetamines. In mid-1967, tablets containing 20 mg (later 10 mg) of STP were widely distributed in the Haight-Ashbury District of San Francisco under the name of STP, having been manufactured by underground chemists Owsley Stanley and Tim Scully. This short-lived appearance of STP on the black market proved disastrous ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Controlled Drugs And Substances Act
The ''Controlled Drugs and Substances Act'' (french: Loi réglementant certaines drogues et autres substances) (the ''Act'') is Canada's federal drug control statute. Passed in 1996 under Prime Minister Jean Chrétien's government, it repeals the ''Narcotic Control Act'' and Parts III and IV of the ''Food and Drugs Act'', and establishes eight Schedules of controlled substances and two Classes of precursors. It provides that "The Governor in Council may, by order, amend any of Schedules I to VIII by adding to them or deleting from them any item or portion of an item, where the Governor in Council deems the amendment to be necessary in the public interest." The ''Act'' serves as the implementing legislation for 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. Amendments to the act In November 2007, the Justice Minister Rob Nicholson intr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Science (journal)
''Science'', also widely referred to as ''Science Magazine'', is the peer-reviewed academic journal of the American Association for the Advancement of Science (AAAS) and one of the world's top academic journals. It was first published in 1880, is currently circulated weekly and has a subscriber base of around 130,000.

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 to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Psi-DOM
Ψ-DOM, or 2,6-dimethoxy-4-methylamphetamine, is a hallucinogenic, psychedelic drug and a structural isomer of the better-known hallucinogen DOM. Ψ-DOM was first reported by Alexander Shulgin in his book '' PiHKAL''. Ψ-DOM has similar effects to DOM, but is only around one third to one half the potency, with an active dose reported to be between 15-25 milligrams. The effects of Ψ-DOM last for around six to eight hours. The activity of Ψ-DOM (and Ψ-2C-T-4) demonstrates that the two methoxy groups on the psychedelic phenethylamines are not strictly limited to the 2,5-positions on the phenyl ring. Indeed, any of the 2Cx or DOx series of drugs could alternatively be made as the 2,6-isomer and would still be expected to show similar activity, although slightly less potent. In theory this would vastly expand the range of different hallucinogens that could be derived from this family of drugs. The 2,6-isomer of another similar drug 2C-D-FLY (see 2C-B-FLY) has also been made by Dav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Journal Of Pharmacology And Experimental Therapeutics
The ''Journal of Pharmacology and Experimental Therapeutics'' (a.k.a. JPET) is a peer-reviewed scientific journal covering pharmacology. It has been published since 1909 by the American Society for Pharmacology and Experimental Therapeutics (ASPET). The journal publishes mainly original research articles, and accepts papers covering all aspects of the interactions of chemicals with biological systems. John Jacob Abel founded ASPET in December 1908 when he invited 18 pharmacologists to his laboratory in order to organize a new society. At the end of the meeting Abel announced the establishment of JPET. According to the ''Journal Citation Reports'', the journal received a 2021 impact factor of 4.4. Further readingPharm. Exp.

5-HT
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) hydroxylation of the 5 position on the ring (forming the intermediate 5-hydroxytryptophan), and then decarboxylation to produce serotonin. Serotonin is primarily found in the enteric nervous system located in the 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, pulmonary neuroendocrine cells and taste receptor cells in the tongue. Additionally, serotonin is stored in blood platelets and is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Enantiomer
In chemistry, an enantiomer ( /ɪˈnænti.əmər, ɛ-, -oʊ-/ ''ih-NAN-tee-ə-mər''; from Ancient Greek ἐνάντιος ''(enántios)'' 'opposite', and μέρος ''(méros)'' 'part') – also called optical isomer, antipode, or optical antipode – is one of two stereoisomers that are non-superposable onto their own mirror image. Enantiomers are much like one's right and left hands, when looking at the same face, they cannot be superposed onto each other. No amount of reorientation will allow the four unique groups on the chiral carbon (see Chirality (chemistry)) to line up exactly. The number of stereoisomers a molecule has can be determined by the number of chiral carbons it has. Stereoisomers include both enantiomers and diastereomers. Diastereomers, like enantiomers, share the same molecular formula and are non-superposable onto each other however, they are not mirror images of each other. A molecule with chirality rotates plane-polarized light. A mixture of equals a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chirality (chemistry)
In chemistry, a molecule or ion is called chiral () if it cannot be superposed on its mirror image by any combination of rotation (geometry), rotations, translation (geometry), translations, and some Conformational isomerism, conformational changes. This geometric property is called chirality (). The terms are derived from Ancient Greek χείρ (''cheir'') 'hand'; which is the canonical example of an object with this property. A chiral molecule or ion exists in two stereoisomers that are mirror images of each other, called enantiomers; they are often distinguished as either "right-handed" or "left-handed" by their absolute configuration or some other criterion. The two enantiomers have the same chemical properties, except when reacting with other chiral compounds. They also have the same physics, physical properties, except that they often have opposite optical activity, optical activities. A homogeneous mixture of the two enantiomers in equal parts is said to be racemic mixtu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
5-HT2
The 5-HT2 receptors are a subfamily of 5-HT receptors that bind the endogenous neurotransmitter serotonin (5-hydroxytryptamine, 5-HT). The 5-HT2 subfamily consists of three G protein-coupled receptors (GPCRs) which are coupled to Gq/G11 and mediate excitatory In neuroscience, an excitatory postsynaptic potential (EPSP) is a postsynaptic potential that makes the postsynaptic neuron more likely to fire an action potential.

Agonist
An agonist is a chemical that activates a receptor to produce a biological response. Receptors are cellular proteins whose activation causes the cell to modify what it is currently doing. In contrast, an antagonist blocks the action of the agonist, while an inverse agonist causes an action opposite to that of the agonist. Etymology From the Greek αγωνιστής (agōnistēs), contestant; champion; rival < αγων (agōn), contest, combat; exertion, struggle < αγω (agō), I lead, lead towards, conduct; drive Types of agonists can be activated by either endogenous agonists (such as |
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 ...
