Ethylone
Ethylone, also known as 3,4-methylenedioxy-''N''-ethylcathinone (MDEC, βk-MDEA), is a recreational designer drug classified as an entactogen, stimulant, and psychedelic of the phenethylamine, amphetamine, and cathinone chemical classes. It is the β-keto analogue of MDEA ("Eve"). Ethylone has only a short history of human use and is reported to be less potent than its relative methylone. In the United States, it began to be found in cathinone products in late 2011. Very little data exists about the pharmacological properties, metabolism, and toxicity of ethylone, and although several ethylone-related deaths have been reported, the cause of death was not due to ingestion of ethylone. Pharmacokinetics Analysis of human and rat urine for the metabolites of bk-amphetamines suggested that ethylone was degraded in the following metabolic steps: # N- deethylation to the primary amine. # Reduction of the keto moiety to the respective alcohol.

Substituted Cathinone
Substituted cathinones, which include some stimulants and entactogens, are derivatives of cathinone. They feature a phenethylamine core with an alkyl group attached to the alpha carbon, and a ketone group attached to the beta carbon, along with additional substitutions. Cathinone occurs naturally in the plant khat whose leaves are chewed as a recreational drug. List of substituted cathinones The derivatives may be produced by substitutions at four locations of the cathinone molecule: * R1 = hydrogen, or any combination of one or more alkyl, alkoxy, alkylenedioxy, haloalkyl or halide substituents * R2 = hydrogen or any alkyl group * R3 = hydrogen, any alkyl group, or incorporation in a cyclic structure * R4 = hydrogen, any alkyl group, or incorporation in a cyclic structure The following table displays notable derivatives that have been reported: Legality On 2 April 2010, the Advisory Council on the Misuse of Drugs in the UK announced that a broad structure-based ba ...

Benzylone
Benzylone (also known as 3,4-Methylenedioxy-N-benzylcathinone or BMDP), is a recreational designer drug from the substituted cathinone family, with stimulant effects. It has been commonly encountered in seizures of street drug samples but appears to have relatively low potency on its own, being mainly found as a component of mixtures with other related drugs.

Racemic Mixture
In chemistry, a racemic mixture, or racemate (), is one that has equal amounts of left- and right-handed enantiomers of a chiral molecule or salt. Racemic mixtures are rare in nature, but many compounds are produced industrially as racemates. History The first known racemic mixture was racemic acid, which Louis Pasteur found to be a mixture of the two enantiomeric isomers of tartaric acid. He manually separated the crystals of a mixture by hand, starting from an aqueous solution of the sodium ammonium salt of racemate tartaric acid. Pasteur benefited from the fact that ammonium tartrate salt that gives enantiomeric crystals with distinct crystal forms (at 77 °F). Reasoning from the macroscopic scale down to the molecular, he reckoned that the molecules had to have non-superimposable mirror images. A sample with only a single enantiomer is an ''enantiomerically pure'' or ''enantiopure'' compound. Etymology From racemic acid found in grapes; from Latin ''racemus'', meani ...

Demethylation
Demethylation is the chemical process resulting in the removal of a methyl group (CH3) from a molecule. A common way of demethylation is the replacement of a methyl group by a hydrogen atom, resulting in a net loss of one carbon and two hydrogen atoms. The counterpart of demethylation is methylation. In biochemistry In biochemical systems, the process of demethylation is catalyzed by demethylases. These enzymes oxidize N-methyl groups, which occur in histones and some forms of DNA: :R2N-CH3 + O → R2N-H + CH2O One such oxidative enzyme family is the cytochrome P450. Alpha-ketoglutarate-dependent hydroxylases are active for demethylation of DNA, operating by a similar pathway. These reactions exploit the weak C-H bond adjacent to amines. In particular, 5-methylcytosines in DNA can be demethylated by TET enzymes as illustrated in the figure. TET enzymes are dioxygenases in the family of alpha-ketoglutarate-dependent hydroxylases. A TET enzyme is an alpha-ketoglut ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Designer Drugs
A designer drug is a structural or functional analog of a controlled substance that has been designed to mimic the pharmacological effects of the original drug, while avoiding classification as illegal and/or detection in standard drug tests. Designer drugs include psychoactive substances that have been designated by the European Union as new psychoactive substances (NPS) as well as analogs of performance-enhancing drugs such as designer steroids. Some of these were originally synthesized by academic or industrial researchers in an effort to discover more potent derivatives with fewer side effects, and shorter duration (and possibly also because it is easier to apply for patents for new molecules) and were later co-opted for recreational use. Other designer drugs were prepared for the first time in clandestine laboratories. Because the efficacy and safety of these substances have not been thoroughly evaluated in animal and human trials, the use of some of these drugs may result i ...

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.

5-Methylethylone
5-Methylethylone (5-methyl-βk-MDEA, 5ME) is an empathogen, stimulant and psychedelic drug of the amphetamine, phenethylamine, and cathinone chemical classes. It is structurally related to ethylone, a novel designer drug. Relatively little data exists about the pharmacological properties, metabolism, and toxicity of 5-methylethylone, though it has been sold as a designer drug. Legal status United States 5-Methylethylone is unscheduled in the United States, but it is not currently approved by the Food and Drug Administration for human consumption. The state of Vermont lists it as a regulated drug. Vermont Health Regulations See also * 5-Methyl-MDA * |
Alcohol (chemistry)
In chemistry, an alcohol is a type of organic compound that carries at least one hydroxyl () functional group bound to a saturated carbon atom. The term ''alcohol'' originally referred to the primary alcohol ethanol (ethyl alcohol), which is used as a drug and is the main alcohol present in alcoholic drinks. An important class of alcohols, of which methanol and ethanol are the simplest examples, includes all compounds which conform to the general formula . Simple monoalcohols that are the subject of this article include primary (), secondary () and tertiary () alcohols. The suffix ''-ol'' appears in the IUPAC chemical name of all substances where the hydroxyl group is the functional group with the highest priority. When a higher priority group is present in the compound, the prefix ''hydroxy-'' is used in its IUPAC name. The suffix ''-ol'' in non-IUPAC names (such as paracetamol or cholesterol) also typically indicates that the substance is an alcohol. However, some compou ...

Organic Redox Reaction
Organic reductions or organic oxidations or organic redox reactions are redox reactions that take place with organic compounds. In organic chemistry oxidations and reductions are different from ordinary redox reactions, because many reactions carry the name but do not actually involve electron transfer.March Jerry; (1985). Advanced Organic Chemistry reactions, mechanisms and structure (3rd ed.). New York: John Wiley & Sons, inc. Instead the relevant criterion for organic oxidation is gain of oxygen and/or loss of hydrogen, respectively.''Organic Redox Systems: Synthesis, Properties, and Applications'', Tohru Nishinaga 2016 Simple functional groups can be arranged in order of increasing oxidation state. The oxidation numbers are only an approximation: When methane is oxidized to carbon dioxide its oxidation number changes from −4 to +4. Classical reductions include alkene reduction to alkanes and classical oxidations include oxidation of alcohols to aldehydes. In oxidations ...
