Cyclopyrrolone
Cyclopyrrolones are a family of hypnotic and anxiolytic nonbenzodiazepine drugs with similar pharmacological profiles to the benzodiazepine derivatives. Although cyclopyrrolones are chemically unrelated to benzodiazepines, they function via the benzodiazepine receptor of neurotransmitter GABA. The best-known cyclopyrrolone derivatives are zopiclone (Imovane) and its active single-enantiomer component, eszopiclone (Lunesta), which are used to treat insomnia, and have a known potential for abuse. Other cyclopyrrolones include: * Pagoclone – anxiolytic * Pazinaclone – anxiolytic * Suproclone – anxiolytic * Suriclone Suriclone (Suril) is a sedative and anxiolytic drug in the cyclopyrrolone family of drugs.

Zopiclone
Zopiclone, sold under the brand name Imovane among others, is a nonbenzodiazepine used to treat insomnia, difficulty sleeping. Zopiclone is molecularly distinct from benzodiazepine drugs and is classed as a cyclopyrrolone. However, zopiclone increases the normal transmission of the neurotransmitter gamma-aminobutyric acid (GABA) in the central nervous system, via modulating GABAA receptor, GABAA receptors similarly to the way benzodiazepine drugs do. Zopiclone is a sedative. It works by causing a depression or tranquilization of the central nervous system. After prolonged use, the body can become accustomed to the effects of zopiclone. When the dose is then reduced or the drug is abruptly stopped, withdrawal symptoms may result. These can include a range of symptoms similar to those of benzodiazepine withdrawal. Although withdrawal symptoms from therapeutic doses of zopiclone and its isomers (i.e., eszopiclone) do not typically present with convulsions and are therefore not cons ...

Suriclone
Suriclone (Suril) is a sedative and anxiolytic drug in the cyclopyrrolone family of drugs. Other cyclopyrrolone drugs include zopiclone and pagoclone. Suriclone has a very similar pharmacological profile to the benzodiazepine family of drugs including sedative and anxiolytic properties but with less amnestic effects, and its chemical structure A chemical structure determination includes a chemist's specifying the molecular geometry and, when feasible and necessary, the electronic structure of the target molecule or other solid. Molecular geometry refers to the spatial arrangement of at ... is quite different from that of the benzodiazepine drugs. The mechanism of action by which suriclone produces its sedative and anxiolytic effects is by modulating GABAA receptors, although suriclone is more subtype-selective than most benzodiazepines.

Pazinaclone
Pazinaclone (DN-2327) is a sedative and anxiolytic drug in the cyclopyrrolone family of drugs. Some other cyclopyrrolone drugs include zopiclone and eszopiclone. Pazinaclone has a very similar pharmacological profile to the benzodiazepines including sedative and anxiolytic properties, but with less amnestic effects, and at low doses it is a relatively selective anxiolytic, with sedative effects only appearing at higher doses. Pazinaclone produces its sedative and anxiolytic effects by acting as a partial agonist at GABAA benzodiazepine receptors, although pazinaclone is more subtype-selective than most benzodiazepines. Synthesis Reaction of 2-amino-7-chloro-1,8-naphthyridine with phthalic anhydride leads to the corresponding phthalimide. Selective reduction of one of the imide carbonyl groups in essence converts that to an aldehyde. Condensation with ''tert''-butyl(triphenylphosphoranylidene)acetate gives the Wittig product. The carboxylic acid is then treated with diethyl cy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Suproclone
Suproclone is a sedative and anxiolytic drug in the cyclopyrrolone family of drugs, developed by the French pharmaceutical company Rhône-Poulenc. Other cyclopyrrolone drugs include zopiclone, pagoclone and suriclone. Suproclone is very similar in structure to the related drug suriclone Suriclone (Suril) is a sedative and anxiolytic drug in the cyclopyrrolone family of drugs. Other cyclopyrrolone drugs include zopiclone and pagoclone. Suriclone has a very similar pharmacological profile to the benzodiazepine family of drugs inc ..., but little information has been published about it specifically. However it can be expected that the mechanism of action by which suproclone produces its sedative and anxiolytic effects is by modulating benzodiazepine receptors (resulting in an increased response to endogenous GABA), in a similar manner to other drugs of this class.

Eszopiclone
Eszopiclone, sold under the brand-name Lunesta among others such as Night Calm in Egypt, is a medication used in the treatment of insomnia. Evidence supports slight to moderate benefit up to six months. It is taken orally. Common side effects include headache, dry mouth, nausea, and dizziness. Severe side effects may include suicidal thoughts, unhealthy non-medical use, hallucinations, and angioedema. Greater care is recommended in those with liver problems and older people. Rapid decreasing of the dose may result in withdrawal. Eszopiclone is classified as a nonbenzodiazepine sedative hypnotic and as a cyclopyrrolone. It is the S-stereoisomer of zopiclone. It works by interacting with the GABA receptors. Approved for medical use in the United States in 2004, eszopiclone is available as generic medication. In 2020, it was the 232nd most commonly prescribed medication in the United States, with more than 1million prescriptions. Eszopiclone is not sold in the European Union, as o ...

Pagoclone
Pagoclone is an anxiolytic agent from the cyclopyrrolone family, related to better-known drugs such as the sleeping medication zopiclone. It was synthesized by a French team working for Rhone-Poulenc & Rorer S.A. Pagoclone belongs to the class of nonbenzodiazepines, which have similar effects to the older benzodiazepine group, but with quite different chemical structures. It was never commercialised. It binds with roughly equivalent high affinity (0.7–9.1 nM) to the benzodiazepine binding site of human GABAA receptors containing either an α1, α2, α3 or α5 subunit. It is a partial agonist at α1-, α2- and α5-containing GABAA receptors and a full agonist at receptors containing an α3 subunit. In rats 5′-hydroxypagoclone was identified as a major metabolite. This metabolite has a considerably greater efficacy at the α1 subtype than the parent compound and was shown to have significant anxiolytic-like activity and to produce sedation. In contrast to zopiclone, pagoclone p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anxiolytic
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nonbenzodiazepine
Nonbenzodiazepines (), sometimes referred to colloquially as Z-drugs (as many of their names begin with the letter "z"), are a class of psychoactive drugs that are very benzodiazepine-like in nature. They are used in the treatment of sleep problems, and for their anxiolytic effects. Nonbenzodiazepine pharmacodynamics are almost entirely the same as benzodiazepine drugs and therefore exhibit similar benefits, side-effects, and risks. However, nonbenzodiazepines have dissimilar or entirely different chemical structures and are therefore unrelated to benzodiazepines on a molecular level. Classes Currently, the major chemical classes of nonbenzodiazepines are: Imidazopyridines * Alpidem * Necopidem * Saripidem * Zolpidem (Ambien, Ambien CR, Intermezzo, Zolpimist, Edluar, Ivadal, Sanval, Stilnox, etc.) Pyrazolopyrimidines * Divaplon * Fasiplon * Indiplon * Lorediplon * Ocinaplon * Panadiplon * Taniplon * Zaleplon (Sonata, Starnoc, Andante) Cyclopyrrolones * Eszopiclone (Lunesta, V ...

Benzodiazepine
Benzodiazepines (BZD, BDZ, BZs), sometimes called "benzos", are a class of depressant drugs whose core chemical structure is the fusion of a benzene ring and a diazepine ring. They are prescribed to treat conditions such as anxiety disorders, insomnia, and seizures. The first benzodiazepine, chlordiazepoxide (Librium), was discovered accidentally by Leo Sternbach in 1955 and was made available in 1960 by Hoffmann–La Roche, who soon followed with diazepam (Valium) in 1963. By 1977, benzodiazepines were the most prescribed medications globally; the introduction of selective serotonin reuptake inhibitors (SSRIs), among other factors, decreased rates of prescription, but they remain frequently used worldwide. Benzodiazepines are depressants that enhance the effect of the neurotransmitter gamma-aminobutyric acid (GABA) at the GABAA receptor, resulting in sedative, hypnotic ( sleep-inducing), anxiolytic (anti-anxiety), anticonvulsant, and muscle relaxant properties.

GABAA Receptor
The GABAA receptor (GABAAR) is an ionotropic receptor and ligand-gated ion channel. Its endogenous ligand is γ-aminobutyric acid (GABA), the major inhibitory neurotransmitter in the central nervous system. Upon opening, the GABAA receptor on the postsynaptic cell is selectively permeable to chloride ions (Cl−) and, to a lesser extent, bicarbonate ions (HCO3−). Depending on the membrane potential and the ionic concentration difference, this can result in ionic fluxes across the pore. If the membrane potential is higher than the equilibrium potential (also known as the reversal potential) for chloride ions, when the receptor is activated Cl− will flow into the cell. This causes an inhibitory effect on neurotransmission by diminishing the chance of a successful action potential occurring at the postsynaptic cell. The reversal potential of the GABAA-mediated inhibitory postsynaptic potential (IPSP) in normal solution is −70 mV, contrasting the GABAB IPSP (-100 mV). T ...
