Keramin Minsk Players
Amfepramone, also known as diethylpropion, is a stimulant drug of the phenethylamine, amphetamine, and cathinone classes that is used as an appetite suppressant. It is used in the short-term management of obesity, along with dietary and lifestyle changes. Amfepramone is most closely chemically related to the antidepressant and smoking cessation aid bupropion (previously called amfebutamone), which has also been developed as a weight-loss medicine when in a combination product with naltrexone. Pharmacology Amfepramone itself lacks any affinity for the monoamine transporters and instead functions as a prodrug to ethcathinone. Ethcathinone (and therefore amfepramone as well) is a very weak dopaminergic and serotonergic, and is approximately 10x and 20x stronger on norepinephrine in comparison, respectively. As a result, ethcathinone and amfepramone can essentially be considered a member of the class of drugs known as norepinephrine releasing agents (NRAs). Chemistry Amfepramone c ...

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 ...

Monoamine Transporter
Monoamine transporters (MATs) are protein structures that function as integral plasma-membrane transporters to regulate concentrations of extracellular monoamine neurotransmitters. Three major classes of MATs (SERT, DAT, NET) are responsible for the reuptake of their associated amine neurotransmitters (serotonin, dopamine, norepinephrine). MATs are located just outside the synaptic cleft (peri-synaptically), transporting monoamine transmitter overflow from the synaptic cleft back to the cytoplasm of the pre-synaptic neuron. MAT regulation generally occurs through protein phosphorylation and posttranslational modification. Due to their significance in neuronal signaling, MATs are commonly associated with drugs used to treat mental disorders as well as recreational drugs. Compounds targeting MATs range from medications such as the wide variety of tricyclic antidepressants, selective serotonin reuptake inhibitors such as fluoxetine (Prozac) to stimulant medications such as methylp ...

Controlled Substances Act
The Controlled Substances Act (CSA) is the statute establishing federal government of the United States, federal drug policy of the United States, U.S. drug policy under which the manufacture, importation, possession, use, and distribution of certain substances is regulated. It was passed by the 91st United States Congress as Title II of the Comprehensive Drug Abuse Prevention and Control Act of 1970 and signed into law by President Richard Nixon. The Act also served as the national implementing legislation for the Single Convention on Narcotic Drugs. The legislation created five schedules (classifications), with varying qualifications for a substance to be included in each. Two federal agencies, the Drug Enforcement Administration (DEA) and the Food and Drug Administration (FDA), determine which substances are added to or removed from the various schedules, although the statute passed by Congress created the initial listing. Congress has sometimes scheduled other substances th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brand Names
A brand is a name, term, design, symbol or any other feature that distinguishes one seller's good or service from those of other sellers. Brands are used in business, marketing, and advertising for recognition and, importantly, to create and store value as brand equity for the object identified, to the benefit of the brand's customers, its owners and shareholders. Brand names are sometimes distinguished from generic or store brands. The practice of branding - in the original literal sense of marking by burning - is thought to have begun with the ancient Egyptians, who are known to have engaged in livestock branding as early as 2,700 BCE. Branding was used to differentiate one person's cattle from another's by means of a distinctive symbol burned into the animal's skin with a hot branding iron. If a person stole any of the cattle, anyone else who saw the symbol could deduce the actual owner. The term has been extended to mean a strategic personality for a product or company, ...

Australian Approved Name
An Australian Approved Name (AAN) is a generic drug name set by the Therapeutic Goods Administration (TGA) for use in Australia. In late 2016, the TGA changed several drug names to the corresponding international nonproprietary name (INN), or, in cases where an INN was not available (as with asparaginase), another established generic name, such as the United States Adopted Name (USAN).

British Approved Name
A British Approved Name (BAN) is the official, non-proprietary, or generic name given to a pharmaceutical substance, as defined in the British Pharmacopoeia (BP). The BAN is also the official name used in some countries around the world, because starting in 1953, proposed new names were evaluated by a panel of experts from WHO in conjunction with the BP commission to ensure naming consistency worldwide (an effort leading to the International Nonproprietary Name system). There is also a British Approved Name (Modified) (BANM). Combination preparations BANs are unique in that names are assigned for combination preparations as well as single-drug preparations. For example, the BAN Co-amoxiclav is assigned to preparations containing amoxicillin and clavulanic acid. Most other pharmacopoeias simply refer to combination products by both ingredients in the preparation, in this example "amoxicillin with clavulanic acid". The prefix of "co-" is used for many combination drugs, including ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diethylamine
Diethylamine is an organic compound with the formula (CH3CH2)2NH. It is a secondary amine. It is a flammable, weakly alkaline liquid that is miscible with most solvents. It is a colorless liquid, but commercial samples often appear brown due to impurities. It has a strong ammonia-like odor. Production and uses Diethylamine is made by the alumina-catalyzed reaction of ethanol and ammonia. It is obtained together with ethylamine and triethylamine. Annual production of three ethylamines was estimated in 2000 to be 80,000,000 kg. It is used in the production of corrosion inhibitor ''N'',''N''- diethylaminoethanol, by reaction with ethylene oxide. It is also a precursor to a wide variety of other commercial products. Diethylamine is also sometimes used in the illicit production of LSD. Supramolecular structure Diethylamine is the smallest and simplest molecule that features a supramolecular helix as its lowest energy aggregate. Other similarly sized hydrogen-bonding In c ...

Bromination
In chemistry, halogenation is a chemical reaction that entails the introduction of one or more halogens into a compound. Halide-containing compounds are pervasive, making this type of transformation important, e.g. in the production of polymers, drugs. This kind of conversion is in fact so common that a comprehensive overview is challenging. This article mainly deals with halogenation using elemental halogens (F2, Cl2, Br2, I2). Halides are also commonly introduced using salts of the halides and halogen acids. Many specialized reagents exist for and introducing halogens into diverse substrates, e.g. thionyl chloride. Organic chemistry Several pathways exist for the halogenation of organic compounds, including free radical halogenation, ketone halogenation, electrophilic halogenation, and halogen addition reaction. The nature of the substrate determines the pathway. The facility of halogenation is influenced by the halogen. Fluorine and chlorine are more electrophilic and are m ...

Norepinephrine Releasing Agent
A norepinephrine releasing agent (NRA), also known as an adrenergic releasing agent, is a catecholaminergic type of drug that induces the release of norepinephrine (noradrenaline) and epinephrine (adrenaline) from the pre-synaptic neuron into the synapse. This in turn leads to increased extracellular concentrations of norepinephrine and epinephrine therefore an increase in adrenergic neurotransmission. A closely related type of drug is a norepinephrine reuptake inhibitor (NRI). Another class of drugs that stimulates adrenergic activity is the adrenergic receptor agonist class. Uses and examples NRAs are used for a variety of clinical indications including the following: * For the treatment of attention deficit hyperactivity disorder (ADHD) — e.g., amphetamine, methamphetamine, pemoline * As anorectics in the treatment of obesity — e.g., amphetamine, phentermine, benzphetamine, phenmetrazine, aminorex * As wakefulness-promoting agents in the treatment of narcolepsy ...

Norepinephrine
Norepinephrine (NE), also called noradrenaline (NA) or noradrenalin, is an organic chemical in the catecholamine family that functions in the brain and body as both a hormone and neurotransmitter. The name "noradrenaline" (from Latin '' ad'', "near", and '' ren'', "kidney") is more commonly used in the United Kingdom, whereas "norepinephrine" (from Ancient Greek ἐπῐ́ (''epí''), "upon", and νεφρός (''nephrós''), "kidney") is usually preferred in the United States. "Norepinephrine" is also the international nonproprietary name given to the drug. Regardless of which name is used for the substance itself, parts of the body that produce or are affected by it are referred to as noradrenergic. The general function of norepinephrine is to mobilize the brain and body for action. Norepinephrine release is lowest during sleep, rises during wakefulness, and reaches much higher levels during situations of stress or danger, in the so-called fight-or-flight response. In the ...

Serotonergic
Serotonergic () or serotoninergic () means "pertaining to or affecting serotonin". Serotonin is a neurotransmitter. A synapse is serotonergic if it uses serotonin as its neurotransmitter. A serotonergic neuron ''produces'' serotonin. A substance is serotonergic if it produces its effects via interactions with the serotonin system, such as by stimulating or blocking neurotransmission. A serotonergic or serotoninergic agent is any chemical that modifies the effects of serotonin in the body. Some different types of serotonergics drugs include the following: * Serotonin receptor agonists and antagonists * Serotonin reuptake inhibitors * Serotonin releasing agent A serotonin releasing agent (SRA) is a type of drug that induces the release of serotonin into the neuronal synaptic cleft. A selective serotonin releasing agent (SSRA) is an SRA with less significant or no efficacy in producing neurotransmitter e ...s See also References Parasympathetic nervous system Neurochemistr ...
