Gamma-Hydroxyvaleric Acid
γ-Hydroxyvaleric acid (GHV), also known as 4-methyl-GHB, is a designer drug related to γ-hydroxybutyric acid (GHB). It is sometimes seen on the grey market as a legal alternative to GHB, but with lower potency and higher toxicity, properties which have tended to limit its recreational use. γ-Valerolactone (GVL) acts as a prodrug to GHV, analogously to how γ-butyrolactone (GBL) is a prodrug to GHB.

Designer Drug
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 ...

γ-hydroxybutyric Acid
''gamma''-Hydroxybutyric acid (or γ-hydroxybutyric acid (GHB), also known as 4-hydroxybutanoic acid) is a naturally occurring neurotransmitter and a depressant drug. It is a precursor to GABA, glutamate, and glycine in certain brain areas. It acts on the GHB receptor and is a weak agonist at the GABAB receptor. GHB has been used in the medical setting as a general anesthetic and as treatment for cataplexy, narcolepsy, and alcoholism. It is also used illegally as an intoxicant, as an athletic-performance enhancer, as a date-rape drug, and as a recreational drug. It is commonly used in the form of a salt, such as sodium γ-hydroxybutyrate (NaGHB, sodium oxybate, or Xyrem) or potassium γ-hydroxybutyrate (KGHB, potassium oxybate). GHB is also produced as a result of fermentation, and is found in small quantities in some beers and wines, beef, and small citrus fruits. Succinic semialdehyde dehydrogenase deficiency is a disease that causes GHB to accumulate in the blood. Medic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grey Market
A grey market or dark market (sometimes confused with the similar term " parallel market") is the trade of a commodity through distribution channels that are not authorized by the original manufacturer or trade mark proprietor. Grey market products (grey goods) are products traded outside the authorized manufacturer's channel. Etymology Manufacturers of computers, telecom, and technology equipment often sell these products through distributors. Most distribution agreements require the distributor to resell the products strictly to end users. However, some distributors choose to resell products to other resellers. In the late 1980s, manufacturers labelled the resold products as the "grey market". The legality of selling "grey market" products depends on a number of factors. Courts in the United States and in the EU make a number of assessments, including an examination of the physical and non-physical differences between the "grey market" and authorized products to determin ...

Legal
Law is a set of rules that are created and are enforceable by social or governmental institutions to regulate behavior,Robertson, ''Crimes against humanity'', 90. with its precise definition a matter of longstanding debate. It has been variously described as a science and as the art of justice. State-enforced laws can be made by a group legislature or by a single legislator, resulting in statutes; by the executive through decrees and regulations; or established by judges through precedent, usually in common law jurisdictions. Private individuals may create legally binding contracts, including arbitration agreements that adopt alternative ways of resolving disputes to standard court litigation. The creation of laws themselves may be influenced by a constitution, written or tacit, and the rights encoded therein. The law shapes politics, economics, history and society in various ways and serves as a mediator of relations between people. Legal systems vary between jurisdictions ...

γ-Valerolactone
γ-Valerolactone (GVL) is an organic compound with the chemical formula, formula C5H8O2. This colourless liquid is one of the more common lactones. GVL is chiral but is usually used as the racemate. It is readily obtained from cellulosic biomass and is a potential fuel and green solvent. GVL behaves as a prodrug to gamma-Hydroxyvaleric acid, γ-hydroxyvaleric acid (GHV), a drug with similar effects to those of gamma-Hydroxybutyric acid, γ-hydroxybutyric acid (GHB), albeit with less potency in comparison. Because GHB is controlled in many parts of the world, while GVL is not, GVL has gained popularity as a legal substitute for GHB. Synthesis GVL is produced from levulinic acid, which is obtained from hexoses. In a typical process, cellulosic biomasses, such as corn stover, sawgrass, or wood, is hydrolysed into glucose and other sugars using acid catalysts. The resulting glucose can then be dehydrated via hydroxymethylfurfural to yield formic acid and levulinic acid, which cycl ...

Prodrug
A prodrug is a medication or compound that, after intake, is metabolized (i.e., converted within the body) into a pharmacologically active drug. Instead of administering a drug directly, a corresponding prodrug can be used to improve how the drug is absorbed, distributed, metabolized, and excreted (ADME). Prodrugs are often designed to improve bioavailability when a drug itself is poorly absorbed from the gastrointestinal tract. A prodrug may be used to improve how selectively the drug interacts with cells or processes that are not its intended target. This reduces adverse or unintended effects of a drug, especially important in treatments like chemotherapy, which can have severe unintended and undesirable side effects. History Many herbal extracts historically used in medicine contain glycosides (sugar derivatives) of the active agent, which are hydrolyzed in the intestines to release the active and more bioavailable aglycone. For example, salicin is a β-D-glucopyranosid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1,4-Butanediol
1,4-Butanediol, colloquially known as BD or BDO, is a primary alcohol, and an organic compound, with the formula HOCH2CH2CH2CH2OH. It is a colorless viscous liquid. It is one of four stable isomers of butanediol. Synthesis In industrial synthesis, acetylene reacts with two equivalents of formaldehyde to form 1,4-butynediol. Hydrogenation of 1,4-butynediol gives 1,4-butanediol. It is also manufactured on an industrial scale from maleic anhydride in the Davy process, which is first converted to the methyl maleate ester, then hydrogenated. Other routes are from butadiene, allyl acetate and succinic acid. A biological route to BD has been commercialized that uses a genetically modified organism. The biosynthesis proceeds via 4-hydroxybutyrate. Industrial use 1,4-Butanediol is used industrially as a solvent and in the manufacture of some types of plastics, elastic fibers and polyurethanes. In organic chemistry, 1,4-butanediol is used for the synthesis of γ-butyrolacto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aceburic Acid
Aceburic acid (INN), also known as 4-acetoxybutanoic acid or 4-hydroxybutyric acid acetate, is drug described as an analgesic which was never marketed. It is the acetyl ester of gamma-hydroxybutyrate (GHB, which is 4-hydroxybutanoic acid), and based on its structural relation to GHB, is likely to behave as a prodrug to it.

Valerenic Acid
Valerenic acid is a sesquiterpenoid constituent of the essential oil of the valerian plant. Valerian is used as a herbal sedative which may be helpful in the treatment of insomnia. Valerenic acid may be at least partly responsible for valerian's sedative effects, in addition to the other valerenic acids hydroxyvalerenic acid and acetoxyvalerenic acid. Valerian supplements are often standardized to contain a particular amount of valerenic acid by weight (often 0.8%). Valerenic acid acts as a subtype-selective GABAA receptor positive allosteric modulator via a binding site in the transmembrane domain at the β+α− interface. At receptors expressed in Xenopus oocytes (frog eggs) it was shown that only assemblies incorporating β2 or β3 subunits were stimulated by valerenic acid. A study in mice demonstrated that a single amino acid substitution (N265M) in the β3 subunit severely decreases the anxiolytic effect. Modulation of ion channel action was not significantly dep ...

Valeric Acid
Valeric acid or pentanoic acid is a straight-chain alkyl carboxylic acid with the chemical formula . Like other low-molecular-weight carboxylic acids, it has an unpleasant odor. It is found in the perennial flowering plant ''Valeriana officinalis'', from which it gets its name. Its primary use is in the synthesis of its esters. Salts and esters of valeric acid are known as valerates or pentanoates. Volatile esters of valeric acid tend to have pleasant odors and are used in perfumes and cosmetics. Several, including ethyl valerate and pentyl valerate are used as food additives because of their fruity flavors. History Valeric acid is a minor constituent of the perennial flowering plant valerian (''Valeriana officinalis''), from which it gets its name. The dried root of this plant has been used medicinally since antiquity. The related isovaleric acid shares its unpleasant odor and their chemical identity was investigated by oxidation of the components of fusel alcohol, which in ...

Hydroxy Acids
α-Hydroxy acids, or alpha hydroxy acids (AHAs), are a class of chemical compounds that consist of a carboxylic acid with a hydroxyl group substituent on the adjacent (alpha) carbon. Prominent examples are glycolic acid, lactic acid, mandelic acid and citric acid. Although these compounds are related to the ordinary carboxylic acids and are therefore weak acids, their chemical structure allows for the formation of an internal hydrogen bond between the hydrogen at the hydroxyl group and one of the oxygen atoms of the carboxylic group. The net effect is an increase in acidity. For example, the pKa of lactic acid is 3.86, while that of the unsubstituted propionic acid is 4.87; a full pKa unit difference means that lactic acid is ten times stronger than propionic acid. Industrial applications Feed additives 2-Hydroxy-4-(methylthio)butyric acid is produced commercially as a racemic mixture to substitute for methionine in animal feed. In nature, the same compound is an interm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
