Etifelmine
Etifelmine (INN; also known as gilutensin) is a stimulant drug. It was used for the treatment of hypotension (low blood pressure). Synthesis The base catalyzed reaction between benzophenone 19-61-9(1) and butyronitrile 09-74-0(2) gives 2- ydroxy(diphenyl)methylutanenitrile 2101-20-8(3). Catalytic hydrogenation reduces the nitrile group to a primary amine giving 1,1-diphenyl-2-ethyl-3-aminopropanol 2101-87-7(4). The tertiary hydroxyl group is dehydrated by treatment with anhydrous hydrogen chloride gas, completing the synthesis of Etifelmine (5).

Butyronitrile
Butyronitrile or butanenitrile or propyl cyanide, is a nitrile with the formula C3H7CN. This colorless liquid is miscible with most polar organic solvents. Uses Butyronitrile is mainly used as a precursor to the poultry drug amprolium.Peter Pollak, Gérard Romeder, Ferdinand Hagedorn, Heinz-Peter Gelbke "Nitriles" ''Ullmann's Encyclopedia of Industrial Chemistry'' 2002, Wiley-VCH, Weinheim. It also has recognized use in the synthesis of Etifelmine. Synthesis Butyronitrile is prepared industrially by the ammoxidation of ''n''-butanol: :C3H7CH2OH + NH3 + O2 → C3H7CN + 3 H2O Occurrence in space Butyronitrile has been detected in the Large Molecule Heimat The Large Molecule Heimat is a dense gas cloud located in the molecular cloud Sagittarius B2.

Pridefine
Pridefine (AHR-1,118) is a drug which was investigated as an antidepressant in the late 1970s and early 1980s, but was never marketed. It acts as a balanced reuptake inhibitor of serotonin, dopamine, and norepinephrine, and also has some weak releasing activity. In clinical trials pridefine was found to be as efficacious as the tricyclic antidepressants amitriptyline and imipramine in the treatment of major depressive disorder but was much more tolerable in comparison and also had an earlier onset of action. It has been shown to be effective in the treatment of alcoholism as well.

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 drug, sympathomimetic effects. Stimulants are widely used throughout the world as prescription medicines as well as without a prescription (either legally or Prohibition (drugs), illicitly) as performance-enhancing substance, performance-enhancing or recreational drug use, recreational drugs. Among narcotics, stimulants produce a noticeable crash or ''Comedown (drugs), 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 p ...

Hypotension
Hypotension is low blood pressure. Blood pressure is the force of blood pushing against the walls of the arteries as the heart pumps out blood. Blood pressure is indicated by two numbers, the systolic blood pressure (the top number) and the diastolic blood pressure (the bottom number), which are the maximum and minimum blood pressures, respectively. A systolic blood pressure of less than 90 millimeters of mercury (mmHg) or diastolic of less than 60 mmHg is generally considered to be hypotension. Different numbers apply to children. However, in practice, blood pressure is considered too low only if noticeable symptoms are present. Symptoms include dizziness or lightheadedness, confusion, feeling tired, weakness, headache, blurred vision, nausea, neck or back pain, an irregular heartbeat or feeling that the heart is skipping beats or fluttering, or fainting. Hypotension is the opposite of hypertension, which is high blood pressure. It is best understood as a physiological st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Benzophenone
Benzophenone is the organic compound with the formula (C6H5)2CO, generally abbreviated Ph2CO. It is a white solid that is soluble in organic solvents. Benzophenone is a widely used building block in organic chemistry, being the parent diarylketone. Uses Benzophenone can be used as a photo initiator in UV(Ultra-violet)-curing applications such as inks, imaging, and clear coatings in the printing industry. Benzophenone prevents ultraviolet ( UV) light from damaging scents and colors in products such as perfumes and soaps. Benzophenone can also be added to plastic packaging as a UV blocker to prevent photo-degradation of the packaging polymers or its contents. Its use allows manufacturers to package the product in clear glass or plastic (such as a PETE water bottle). Without it, opaque or dark packaging would be required. In biological applications, benzophenones have been used extensively as photophysical probes to identify and map peptide–protein interactions. Benzophenone ...

Catalytic Hydrogenation
Hydrogenation is a chemical reaction between molecular hydrogen (H2) and another compound or element, usually in the presence of a catalyst such as nickel, palladium or platinum. The process is commonly employed to reduce or saturate organic compounds. Hydrogenation typically constitutes the addition of pairs of hydrogen atoms to a molecule, often an alkene. Catalysts are required for the reaction to be usable; non-catalytic hydrogenation takes place only at very high temperatures. Hydrogenation reduces double and triple bonds in hydrocarbons. Process Hydrogenation has three components, the unsaturated substrate, the hydrogen (or hydrogen source) and, invariably, a catalyst. The reduction reaction is carried out at different temperatures and pressures depending upon the substrate and the activity of the catalyst. Related or competing reactions The same catalysts and conditions that are used for hydrogenation reactions can also lead to isomerization of the alkenes from cis to ...

2-MDP
2-MDP (U-23807A) is a dissociative anaesthetic drug which has been found to be an NMDA antagonist and produces similar effects to PCP in animals. The ''levo'' or (-) isomer is the active form of the drug. It also has stimulant effects, having only around one third the potency of amphetamine by weight, but with a long duration of action, lasting more than 24 hours from a single oral dose. Effects The therapeutic action is said to exhibit appetite suppressant and antidepressantShipley GS, Bishop MP, Gallant DM. A controlled evaluation of U-23,807A in the neurotic depressive syndrome.

Amines
In chemistry, amines (, ) are compounds and functional groups that contain a basic nitrogen atom with a lone pair. Amines are formally derivatives of ammonia (), wherein one or more hydrogen atoms have been replaced by a substituent such as an alkyl or aryl group (these may respectively be called alkylamines and arylamines; amines in which both types of substituent are attached to one nitrogen atom may be called alkylarylamines). Important amines include amino acids, biogenic amines, trimethylamine, and aniline; Inorganic derivatives of ammonia are also called amines, such as monochloramine (). The substituent is called an amino group. Compounds with a nitrogen atom attached to a carbonyl group, thus having the structure , are called amides and have different chemical properties from amines. Classification of amines Amines can be classified according to the nature and number of substituents on nitrogen. Aliphatic amines contain only H and alkyl substituents. Aromatic ...
