Viqualine
Viqualine (INN) (developmental code name PK-5078) is an antidepressant and anxiolytic drug that was never marketed. It acts as a potent and selective serotonin releasing agent and serotonin reuptake inhibitor. In addition, viqualine displaces diazepam from the GABAA receptor and produces benzodiazepine-like effects, indicating that it is also a positive allosteric modulator of the benzodiazepine site of the GABAA receptor. The drug has mainly been researched as a potential treatment for alcoholism.

Indalpine
Indalpine (INN, BAN; brand name Upstène; developmental code name LM-5008) is a selective serotonin reuptake inhibitor (SSRI) class drug that was briefly marketed. It was discovered in 1977 by the pharmacologists Le Fur and Uzan at Pharmuka, a small French pharmaceutical firm, who credit Baron Shopsin and his colleagues at NYU-Bellevue/NYU School of Medicine in New York with providing the basis for their work. They were particularly influenced by the series of "synthesis inhibitor studies" carried out by Shopsin's team during the early to mid 1970s, and in particular, the clinical report by Shopsin et al. (1976) relating to PCPA's rapid reversal of antidepressant response to tranylcypromine in depressed patients. This led to an understanding of the role of the monoamine neurotransmitter serotonin (5-hydroxytryptamine, or 5HT) in the therapeutic effects of the available tricyclic and MAOI class antidepressants. The studies led to widespread recognition of a serotonin hypothesis ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Piperidines
Piperidine is an organic compound with the molecular formula (CH2)5NH. This heterocyclic amine consists of a six-membered ring containing five methylene bridges (–CH2–) and one amine bridge (–NH–). It is a colorless liquid with an odor described as objectionable, and typical of amines. The name comes from the genus name '' Piper'', which is the Latin word for pepper. Although piperidine is a common organic compound, it is best known as a representative structure element within many pharmaceuticals and alkaloids, such as natural-occurring solenopsins. Production Piperidine was first reported in 1850 by the Scottish chemist Thomas Anderson and again, independently, in 1852 by the French chemist Auguste Cahours, who named it. Both of them obtained piperidine by reacting piperine with nitric acid. Industrially, piperidine is produced by the hydrogenation of pyridine, usually over a molybdenum disulfide catalyst: : C5H5N + 3 H2 → C5H10NH Pyridine can also be redu ...

Phenol Ethers
Phenol (also called carbolic acid) is an aromatic organic compound with the molecular formula . It is a white crystalline solid that is volatile. The molecule consists of a phenyl group () bonded to a hydroxy group (). Mildly acidic, it requires careful handling because it can cause chemical burns. Phenol was first extracted from coal tar, but today is produced on a large scale (about 7 billion kg/year) from petroleum-derived feedstocks. It is an important industrial commodity as a precursor to many materials and useful compounds. It is primarily used to synthesize plastics and related materials. Phenol and its chemical derivatives are essential for production of polycarbonates, epoxies, Bakelite, nylon, detergents, herbicides such as phenoxy herbicides, and numerous pharmaceutical drugs. Properties Phenol is an organic compound appreciably soluble in water, with about 84.2 g dissolving in 1000 mL (0.895 M). Homogeneous mixtures of phenol and water at ...

GABAA Receptor Positive Allosteric Modulators
In pharmacology, GABAA receptor positive allosteric modulators are positive allosteric modulator (PAM) molecules that increase the activity of the GABAA receptor protein in the vertebrate central nervous system. GABA is a major inhibitory neurotransmitter in the central nervous system. Upon binding, it triggers the GABAA receptor to open its chloride channel to allow chloride ions into the neuron, making the cell hyperpolarized and less likely to fire. GABAA PAMs increase the effect of GABA by making the channel open more frequently or for longer periods. However, they have no effect if GABA or another agonist is not present. Unlike GABAA receptor agonists, GABAA PAMs do not bind at the same active site as the γ-Aminobutyric acid (GABA) neurotransmitter molecule: they affect the receptor by binding at a different site on the protein. This is called allosteric modulation. In psychopharmacology, GABAA receptor PAMs used as drugs have mainly sedative and anxiolytic ef ...

Anxiolytics
An anxiolytic (; also antipanic or antianxiety agent) is a medication or other intervention that reduces anxiety. This effect is in contrast to anxiogenic agents which increase anxiety. Anxiolytic medications are used for the treatment of anxiety disorders and their related psychological and physical symptoms. Nature of anxiety Anxiety is a naturally-occurring emotion and an innate response of the body to the environmental stimuli. Mild to moderate anxiety would increase level of performance. However, when anxiety levels exceed the tolerability of a person, anxiety disorders may occur. People with anxiety disorders can exhibit fear responses such as defensive behaviors, high levels of alertness and negative emotions, without external stimuli which induce anxiety within an individual. Those with anxiety disorders are also often found to have concurrent psychological disorders, most commonly depression. Anxiety disorders are divided into 6 types in clinical recognition. They are a ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

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 antidepr ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Pipequaline
Pipequaline (INN) (developmental code name PK-8165) is an anxiolytic drug that was never marketed. It possesses a novel chemical structure that is not closely related to other drugs of this type. The drug has a similar pharmacological profile to the benzodiazepine family of drugs, but with mainly anxiolytic properties and very little sedative, amnestic or anticonvulsant effects, and so is classified as a nonbenzodiazepine anxiolytic. Pipequaline acts as a non-selective GABAA receptor partial agonist In pharmacology, partial agonists are drugs that bind to and activate a given receptor, but have only partial efficacy at the receptor relative to a full agonist. They may also be considered ligands which display both agonistic and antagonis .... While its profile of anxiolytic effects without sedation would appear to have potential medical applications, pipequaline has never been developed for medical use and is currently only used in scientific research.

Alcoholism
Alcoholism is, broadly, any drinking of alcohol that results in significant mental or physical health problems. Because there is disagreement on the definition of the word ''alcoholism'', it is not a recognized diagnostic entity. Predominant diagnostic classifications are alcohol use disorder ( DSM-5) or alcohol dependence (ICD-11); these are defined in their respective sources. Excessive alcohol use can damage all organ systems, but it particularly affects the brain, heart, liver, pancreas and immune system. Alcoholism can result in mental illness, delirium tremens, Wernicke–Korsakoff syndrome, irregular heartbeat, an impaired immune response, liver cirrhosis and increased cancer risk. Drinking during pregnancy can result in fetal alcohol spectrum disorders. Women are generally more sensitive than men to the harmful effects of alcohol, primarily due to their smaller body weight, lower capacity to metabolize alcohol, and higher proportion of body fat.

Positive Allosteric Modulator
In pharmacology and biochemistry, allosteric modulators are a group of substances that bind to a receptor to change that receptor's response to stimulus. Some of them, like benzodiazepines, are drugs. The site that an allosteric modulator binds to (i.e., an ''allosteric site'') is not the same one to which an endogenous agonist of the receptor would bind (i.e., an ''orthosteric site''). Modulators and agonists can both be called receptor ligands. Allosteric modulators can be 1 of 3 types either: positive, negative or neutral. Positive types increase the response of the receptor by increasing the probability that an agonist will bind to a receptor (i.e. affinity), increasing its ability to activate the receptor (i.e. efficacy), or both. Negative types decrease the agonist affinity and/or efficacy. Neutral types don't affect agonist activity but can stop other modulators from binding to an allosteric site. Some modulators also work as allosteric agonists. The term "allosteric" deriv ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
