Amitifadine
Amitifadine (developmental code names DOV-21,947, EB-1010) is a serotonin–norepinephrine–dopamine reuptake inhibitor (SNDRI) or so-called triple reuptake inhibitor (TRI) which is or was being developed by Euthymics Bioscience It was under development for the treatment of major depressive disorder, but in May 2013, it was reported that the drug failed to show superior efficacy to placebo in a phase IIb/ IIIa clinical trial. It was suggested that this may have been due to the drug being underdosed. In September 2017, development of amitifadine for the treatment of major depressive disorder was finally officially discontinued. As of September 2017, it is still listed as being under development for the treatment of alcoholism and smoking withdrawal. Pharmacology Ki values for SERT, NET, and DAT of amitifadine are 99 nM, 262 nM, and 213 nM. The IC50 values for serotonin, norepinephrine and dopamine uptake are 12, 23 and 96 nM, respectively Amitifadine reduces the duration o ...

Serotonin–norepinephrine–dopamine Reuptake Inhibitor
A serotonin–norepinephrine–dopamine reuptake inhibitor (SNDRI), also known as a triple reuptake inhibitor (TRI), is a type of drug that acts as a combined reuptake inhibitor of the monoamine neurotransmitters serotonin, norepinephrine, and dopamine. It does this by concomitantly inhibiting the serotonin transporter (SERT), norepinephrine transporter (NET), and dopamine transporter (DAT), respectively. Inhibition of the reuptake of these neurotransmitters increases their extracellular concentrations and, therefore, results in an increase in serotonergic, adrenergic, and dopaminergic neurotransmission. SNDRIs were developed as potential antidepressants and treatments for other disorders, such as obesity, cocaine addiction, attention-deficit hyperactivity disorder (ADHD), and chronic pain. They are an extension of selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs) whereby the addition of dopaminergic action is thought ...

Dopamine
Dopamine (DA, a contraction of 3,4-dihydroxyphenethylamine) is a neuromodulatory molecule that plays several important roles in cells. It is an organic compound, organic chemical of the catecholamine and phenethylamine families. Dopamine constitutes about 80% of the catecholamine content in the brain. It is an amine synthesized by removing a carboxyl group from a molecule of its precursor (chemistry), precursor chemical, L-DOPA, which is biosynthesis, synthesized in the brain and kidneys. Dopamine is also synthesized in plants and most animals. In the brain, dopamine functions as a neurotransmitter—a chemical released by neurons (nerve cells) to send signals to other nerve cells. Neurotransmitters are synthesized in specific regions of the brain, but affect many regions systemically. The brain includes several distinct dopaminergic pathway, dopamine pathways, one of which plays a major role in the motivational component of reward system, reward-motivated behavior.

Chloroarenes
In organic chemistry, an aryl halide (also known as haloarene) is an aromatic compound in which one or more hydrogen atoms, directly bonded to an aromatic ring are replaced by a halide. The haloarene are different from haloalkanes because they exhibit many differences in methods of preparation and properties. The most important members are the aryl chlorides, but the class of compounds is so broad that there are many derivatives and applications. Preparation The two main preparatory routes to aryl halides are direct halogenation and via diazonium salts. Direct halogenation In the Friedel-Crafts halogenation, Lewis acids serve as catalysts. Many metal chlorides are used, examples include iron(III) chloride or aluminium chloride. The most important aryl halide, chlorobenzene is produced by this route. Monochlorination of benzene is always accompanied by formation of the dichlorobenzene derivatives. Arenes with electron donating groups react with halogens even in the absence of ...

Antidepressants
Antidepressants are a class of medication used to treat major depressive disorder, anxiety disorders, chronic pain conditions, and to help manage addictions. Common side-effects of antidepressants include dry mouth, weight gain, dizziness, headaches, sexual dysfunction, and emotional blunting. There is a slight increased risk of suicidal thinking and behavior when taken by children, adolescents, and young adults. Discontinuation syndrome may occur after stopping any antidepressant which resembles recurrent depression. Some research regarding the effectiveness of antidepressants for depression in adults has found benefits, whilst other research has not. Evidence of benefit in children and adolescents is unclear. The twenty-one most commonly prescribed antidepressant medications are more effective than placebo for the short-term (acute) treatments of adults with major depressive disorder. There is debate in the medical community about how much of the observed effects of antidepre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bicifadine
Bicifadine (DOV-220,075) is a serotonin-norepinephrine-dopamine reuptake inhibitor (SNDRI) discovered at American Cyanamid as an analgesic drug candidate, and licensed to DOV Pharmaceutical in 1998 after American Cyanamid was acquired by Wyeth. In January 2007, Dov licensed the rights to bicifadine to XTL Biopharmaceuticals after bicifadine failed in a Phase III clinical trial for chronic lower back pain. XTL ran a PhaseIIb clinical trial for pain caused by diabetic neuropathy, which failed in 2008; XTL terminated the agreement in 2010.

Enantiomer
In chemistry, an enantiomer ( /ɪˈnænti.əmər, ɛ-, -oʊ-/ ''ih-NAN-tee-ə-mər''; from Ancient Greek ἐνάντιος ''(enántios)'' 'opposite', and μέρος ''(méros)'' 'part') – also called optical isomer, antipode, or optical antipode – is one of two stereoisomers that are non-superposable onto their own mirror image. Enantiomers are much like one's right and left hands, when looking at the same face, they cannot be superposed onto each other. No amount of reorientation will allow the four unique groups on the chiral carbon (see Chirality (chemistry)) to line up exactly. The number of stereoisomers a molecule has can be determined by the number of chiral carbons it has. Stereoisomers include both enantiomers and diastereomers. Diastereomers, like enantiomers, share the same molecular formula and are non-superposable onto each other however, they are not mirror images of each other. A molecule with chirality rotates plane-polarized light. A mixture of equals a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tail Suspension Test
The tail suspension test (TST) is an experimental method used in scientific research to measure stress in rodents. It is based on the observation that if a mouse is subjected to short term inescapable stress then the mouse will become immobile. It is used to measure the effectiveness of antidepressant-like agents but there is significant controversy over its interpretation and usefulness. History The TST was introduced in 1985 due to the popularity of a similar test called the forced swim test (FST). However this test only recently became popular in the 2000s where data has shown that animals do show a change in behavior when injected with antidepressants. TST is more reliable when done in conjunction with other depression models such as FST, learned helplessness, anhedonia models and olfactory bulbectomy. Modeling depression Depression is a complex multi-faceted disorder with symptoms that can have multiple causes such as psychological, behavioral, and genetics. Since ...

Minimum Effective Dose
In pharmacology, an effective dose (ED) or effective concentration (EC) is a dose or concentration of a drug that produces a biological response. The term effective dose is used when measurements are taken ''in vivo,'' while the term effective concentration is used when the measurements are taken ''in vitro''. It has been stated that any substance can be toxic at a high enough dose. This concept was exemplified in 2007 when a California woman died of water intoxication in a contest sanctioned by a radio station. The line between efficacy and toxicity is dependent upon the particular patient, although the dose administered by a physician should fall into the predetermined therapeutic window of the drug. The importance of determining the therapeutic range of a drug cannot be overstated. This is generally defined by the range between the minimum effective dose (MED) and the maximum tolerated dose (MTD). The MED is defined as the lowest dose level of a pharmaceutical product that ...
