Amfepramone
Amfepramone, also known as diethylpropion, is a stimulant drug of the substituted phenethylamine, phenethylamine, substituted amphetamine, amphetamine, and substituted cathinone, cathinone chemical class, 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 (pharmacology), 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Substituted Amphetamine
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 ...

Stimulant
Stimulants (also often referred to as psychostimulants or colloquially as uppers) is an overarching term that covers many drugs including those that increase activity of the central nervous system and the body, drugs that are pleasurable and invigorating, or drugs that have sympathomimetic effects. Stimulants are widely used throughout the world as prescription medicines as well as without a prescription (either legally or illicitly) as performance-enhancing or recreational drugs. Among narcotics, stimulants produce a noticeable crash or '' comedown'' at the end of their effects. The most frequently prescribed stimulants as of 2013 were lisdexamfetamine (Vyvanse), methylphenidate (Ritalin), and amphetamine (Adderall). It was estimated in 2015 that the percentage of the world population that had used cocaine during a year was 0.4%. For the category "amphetamines and prescription stimulants" (with "amphetamines" including amphetamine and methamphetamine) the value was 0.7% ...

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'', m ...

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-gluco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Controlled Substances Act
The Controlled Substances Act (CSA) is the statute establishing federal 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 through legislation such as the Hillory J. Farias and Samantha Reid Date- ...

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 comp ...

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, inclu ... [...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 ...

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 an ...

Propiophenone
Propiophenone (shorthand: benzoylethane or BzEt) is an aryl ketone. It is a colorless, sweet-smelling liquid that is insoluble in water, but miscible with organic solvents. It is used in the preparation of other compounds. Production Propiophenone can be prepared by Friedel–Crafts reaction of propanoyl chloride and benzene. It is also prepared commercially by ketonization of benzoic acid and propionic acid over calcium acetate and alumina at 450–550 °C: :C6H5CO2H + CH3CH2CO2H → C6H5C(O)CH2CH3 + CO2 + H2O Ludwig Claisen Rainer Ludwig Claisen (; 14 January 1851 – 5 January 1930) was a German chemist best known for his work with condensations of carbonyls and sigmatropic rearrangements.

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 ...
