Etilamfetamine
Etilamfetamine, also known as ''N''-ethylamphetamine and formerly sold under the brand names Apetinil and Adiparthrol, is a stimulant drug of the substituted amphetamine, amphetamine family. It was invented in the early 20th century and was subsequently used as an anorectic or appetite suppressant in the 1950s, but was not as commonly used as other amphetamines such as amphetamine, methamphetamine, and benzphetamine, and was largely discontinued once newer drugs such as phenmetrazine were introduced. Pharmacology Pharmacodynamics Monoamine releasing agent Ethylamphetamine is a potency (pharmacology), potent dopamine releasing agent (DRA) ''in vitro'', with an of 88.5nM. This is about 10-fold lower than the of dextroamphetamine. The values of ethylamphetamine for induction of norepinephrine and serotonin release were not reported. However, the values of its dextrorotatory enantiomer dextroethylamphetamine have been reported and were 44.1nM, 28.8nM, and 333nM for norepinep ...

Appetite Suppressant
An anorectic is a drug that reduces appetite, resulting in lower food consumption, leading to weight loss. These substances work by affecting the central nervous system or certain neurotransmitters to create a feeling of fullness or reduce the desire to eat. The understanding of anorexiant effects is crucial in the development of interventions for weight management, eating disorders, and related health concerns. The anorexiant effect can be induced through diverse mechanisms, ranging from hormonal regulation to neural signaling. Ghrelin, leptin, and peptide YY are among the hormones involved in appetite control. Additionally, neurotransmitters such as serotonin and dopamine in the central nervous system contribute significantly to the regulation of food intake. By contrast, an appetite stimulant is referred to as orexigenic. The term is (from the Ancient Greek language, Greek and ), and such drugs are also known as anorexigenic, anorexiant, or appetite suppressant. History Us ...

Substituted Amphetamine
Substituted amphetamines, or simply amphetamines, are a chemical class, class of compounds based upon the amphetamine structure; it includes all derivative (chemistry), derivative compounds which are formed by replacing, or substitution reaction, 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, Empathogen-entactogen, empathogens, and hallucinogens, among others. Examples of substituted amphetamines are amphetamine (itself), methamphetamine, ephedrine, cathinone, phentermine, mephentermine, tranylcypromine, bupropion, methoxyphenamine, selegiline, amfepramone, amfepramone (diethylpropion), pyrovalerone, MDMA (ecstasy), and 2,5-dimethoxy-4-methylamphetamine, DOM (STP). Some of amphetamine's substituted Derivative (chemistry), derivatives occur in nature, for example in the leaves of ''Ephedra (genus), Ephedra'' and khat plants. Amphetamine w ...

Diário Oficial Da União
The ''Diário Oficial da União'' (literally ''Official Diary of the Union''), abbreviated DOU, is the government gazette, official gazette of the Federal Government of Brazil, Federal Government of Brazil. It is published since 1 October 1862 and was created via the Imperial Decree 1,177 of its 9 September as the ''Official Journal of the Empire of Brazil''. Its current name was adopted after Brazil became a federal republic, and the "Union" came into being as the legal personality of the new federal government. The official journal is published by the Imprensa Nacional, Brazilian National Press. Though the journal has been published since 1862, it had many predecessors, as follows: # Gazeta do Rio de Janeiro (10/9/1808 – 29.12.1821) # Gazeta do Rio (1/1/1822 – 31/12/1822) # Diário do Governo (2/1/1823 – 28/6/1833) # Diário Fluminense (21/5/1824 – 24/4/1831) # Correio Oficial (1/7/1833 – 30/6/1836) e (2/1/1830 – 30/12/1840) # Without proper journal (31/12/1840 – ...

Norepinephrine
Norepinephrine (NE), also called noradrenaline (NA) or noradrenalin, is an organic compound, organic chemical in the catecholamine family that functions in the brain and human body, body as a hormone, neurotransmitter and neuromodulator. The name "noradrenaline" (from Latin '':wikt:ad-, ad'', "near", and '':wikt:ren, ren'', "kidney") is more commonly used in the United Kingdom and the rest of the world, whereas "norepinephrine" (from Ancient Greek :wikt:ἐπί, ἐπῐ́ (''epí''), "upon", and :wikt:νεφρός, νεφρός (''nephrós''), "kidney") is usually preferred in the United States. "Norepinephrine" is also the international nonproprietary name given to norepinephrine (drug), 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, rise ...

Dopamine Releasing Agent
A dopamine releasing agent (DRA) is a type of drug which induces the release of dopamine in the Body (biology), body and/or brain. No binding selectivity, selective DRAs are currently known. However, non-selective DRAs, including norepinephrine–dopamine releasing agents (NDRAs) like amphetamine and methamphetamine, serotonin–norepinephrine–dopamine releasing agents (SNDRAs) like MDMA and mephedrone, and serotonin–dopamine releasing agents (SDRAs) like 5-chloro-αMT and BK-NM-AMT, are known. A closely related type of drug is a dopamine reuptake inhibitor (DRI). In contrast to the case of DRAs, many selective DRIs are known. Examples of selective DRIs include amineptine, modafinil, and vanoxerine. Selectivity No binding selectivity, selective and robust DRAs are currently known. The lack of known selective DRAs is related to the fact that it has proven extremely difficult to separate dopamine transporter (DAT) affinity (pharmacology), affinity from norepinephrine transpo ...

In Vitro
''In vitro'' (meaning ''in glass'', or ''in the glass'') Research, studies are performed with Cell (biology), cells or biological molecules outside their normal biological context. Colloquially called "test-tube experiments", these studies in biology and its subdisciplines are traditionally done in labware such as test tubes, flasks, Petri dishes, and microtiter plates. Studies conducted using components of an organism that have been isolated from their usual biological surroundings permit a more detailed or more convenient analysis than can be done with whole organisms; however, results obtained from ''in vitro'' experiments may not fully or accurately predict the effects on a whole organism. In contrast to ''in vitro'' experiments, ''in vivo'' studies are those conducted in living organisms, including humans, known as clinical trials, and whole plants. Definition ''In vitro'' (Latin language, Latin for "in glass"; often not italicized in English usage) studies are conducted ...

Dextroamphetamine
Dextroamphetamine (international nonproprietary name, INN: dexamfetamine) is a potent central nervous system (CNS) stimulant and enantiomer of amphetamine that is used in the treatment of attention deficit hyperactivity disorder (ADHD) and narcolepsy. It is also used illicitly to enhance Nootropic, cognitive and athletic Performance-enhancing substance, performance, and recreationally as an aphrodisiac and euphoriant. Dextroamphetamine is generally regarded as the prototype drug, prototypical stimulant. The amphetamine molecule exists as two enantiomers, levoamphetamine and dextroamphetamine. Dextroamphetamine is the Levorotation and dextrorotation, dextrorotatory, or 'right-handed', enantiomer and exhibits more pronounced effects on the central nervous system than levoamphetamine. Pharmaceutical dextroamphetamine sulfate is available as both a brand name and generic drug in a variety of dosage forms. Dextroamphetamine is sometimes prescribed as the inactive prodrug lisdexamfet ...

Serotonin
Serotonin (), also known as 5-hydroxytryptamine (5-HT), is a monoamine neurotransmitter with a wide range of functions in both the central nervous system (CNS) and also peripheral tissues. It is involved in mood, cognition, reward, learning, memory, and physiological processes such as vomiting and vasoconstriction. In the CNS, serotonin regulates mood, appetite, and sleep. Most of the body's serotonin—about 90%—is synthesized in the gastrointestinal tract by enterochromaffin cells, where it regulates intestinal movements. It is also produced in smaller amounts in the brainstem's raphe nuclei, the skin's Merkel cells, pulmonary neuroendocrine cells, and taste receptor cells of the tongue. Once secreted, serotonin is taken up by platelets in the blood, which release it during clotting to promote vasoconstriction and platelet aggregation. Around 8% of the body's serotonin is stored in platelets, and 1–2% is found in the CNS. Serotonin acts as both a vasoconstrictor and vas ...

Phenmetrazine
Phenmetrazine, sold under the brand name Preludin among others, is a stimulant drug first chemical synthesis, synthesized in 1952 and originally used as an appetite suppressant, but withdrawn drug, withdrawn from the market in the 1980s due to widespread drug misuse, misuse. It was initially replaced by its structural analog, analogue phendimetrazine (under the brand name Prelu-2) which functions as a prodrug to phenmetrazine, but now it is rarely prescribed, due to concerns of misuse and drug addiction, addiction. Chemically, phenmetrazine is a substituted amphetamine containing a morpholine ring (chemistry), ring or a substituted phenylmorpholine. Medical uses Phenmetrazine has been used as an appetite suppressant for purposes of weight loss. It was used therapeutically for this indication at a dosage of 25mg two or three times per day (or 50–75mg/day total) in adults. Phenmetrazine has been found to produce similar weight loss to dextroamphetamine in people with obesity. I ...

Dextrorotatory
Optical rotation, also known as polarization rotation or circular birefringence, is the rotation of the orientation of the plane of polarization about the optical axis of linearly polarized light as it travels through certain materials. Circular birefringence and circular dichroism are the manifestations of optical activity. Optical activity occurs only in chiral materials, those lacking microscopic mirror symmetry. Unlike other sources of birefringence which alter a beam's state of polarization, optical activity can be observed in fluids. This can include gases or solutions of chiral molecules such as sugars, molecules with helical secondary structure such as some proteins, and also chiral liquid crystals. It can also be observed in chiral solids such as certain crystals with a rotation between adjacent crystal planes (such as quartz) or metamaterials. When looking at the source of light, the rotation of the plane of polarization may be either to the right (dextrorotatory o ...

Enantiomer
In chemistry, an enantiomer (Help:IPA/English, /ɪˈnænti.əmər, ɛ-, -oʊ-/ Help:Pronunciation respelling key, ''ih-NAN-tee-ə-mər''), also known as an optical isomer, antipode, or optical antipode, is one of a pair of molecular entities which are mirror images of each other and non-superposable. Enantiomer molecules are like right and left hands: one cannot be superposed onto the other without first being converted to its mirror image. It is solely a relationship of chirality (chemistry), chirality and the permanent three-dimensional relationships among molecules or other chemical structures: no amount of re-orientation of a molecule as a whole or conformational isomerism, conformational change converts one chemical into its enantiomer. Chemical structures with chirality rotate plane-polarized light. A mixture of equal amounts of each enantiomer, a ''racemic mixture'' or a ''racemate'', does not rotate light. Stereoisomers include both enantiomers and diastereomers. Diaste ...
