Pruvanserin
Pruvanserin (EMD-281,014, LY-2,422,347) is a selective 5-HT2A receptor antagonist which was under development by Eli Lilly and Company for the treatment of insomnia. It was in phase II clinical trials in 2008 but appears to have been discontinued as it is no longer in the company's development pipeline. In addition to its sleep-improving properties, pruvanserin has also been shown to have antidepressant, anxiolytic, and working memory-enhancing effects in animal studies.

Glemanserin
Glemanserin (International Nonproprietary Name, INN) (developmental code name MDL-11,939) is a drug which acts as a potency (pharmacology), potent and binding selectivity, selective 5-HT2A receptor, 5-HT2A receptor receptor antagonist, antagonist. The first truly selective 5-HT2A ligand to be discovered, glemanserin resulted in the development of the widely used and even more potent and selective 5-HT2A receptor antagonist volinanserin (MDL-100,907), which is a fluorinated structural analog, analogue. Though it was largely superseded in scientific research by volinanserin, glemanserin was investigated clinical trial, clinically for the treatment of generalized anxiety disorder. However, it was ultimately found to be ineffective and was not marketed.

Lenperone
Lenperone (Elanone-V) is a typical antipsychotic of the butyrophenone chemical class. It was first reported as an anti-emetic in 1974, and its use in treatment of acute schizophrenia was reported in 1975. Related early antipsychotic agents include declenperone and milenperone. Lenperone was never approved by the FDA for use in humans in the United States, but prior to 1989 it was approved for use in veterinary medicine for sedation. Synthesis The alkylation between 2-(3-chloropropyl)-2-(4-fluorophenyl)-1,3-dioxolane 308-94-9(1) and 4-(4-fluorobenzoyl)piperidine 6346-57-7(2) gives 2-(p-fluorophenyl)-2--1,3-dioxolaneCID:20318874(3). Deprotection of the ketal function completes the synthesis of lenperone (4).

Roluperidone
Roluperidone (former developmental code names MIN-101, CYR-101, MT-210) is a 5-HT2A and σ2 receptor antagonist under development by Minerva Neurosciences for the treatment of schizophrenia. One of its metabolites also has some affinity for the H1 receptor. Pre-clinical findings provide evidence of the effect of roluperidone on Brain-Derived Neurotrophic Factor (“BDNF”), which has been associated with neurogenesis, neuroplasticity, neuroprotection, synapse regulation, learning and memory. As of May 2018, the drug was in phase III clinical trials. In May 2020, the shares of Minerva Neurosciences plummeted 67% after the trial "failed to meet its primary endpoint of reduction in negative symptoms, and key secondary endpoints of improvement in personal and social performance measurements." However, in August of 2022 Minerva submitted a New Drug Application (NDA) to the Food and Drug Administration (FDA) for the approval of roluperidone for the treatment of schizophrenia. The ...

Hydrochloride
In chemistry, a hydrochloride is an acid salt resulting, or regarded as resulting, from the reaction of hydrochloric acid with an organic base (e.g. an amine). An alternative name is chlorhydrate, which comes from French. An archaic alternative name is muriate, derived from hydrochloric acid's ancient name: muriatic acid. Uses Converting amines into their hydrochlorides is a common way to improve their water solubility, which can be desirable for substances used in medications. The European Pharmacopoeia lists more than 200 hydrochlorides as active ingredients in medications. These hydrochlorides, compared to free bases, may more readily dissolve in the gastrointestinal tract and be absorbed into the bloodstream more quickly. Additionally, many hydrochlorides of amines have a longer shelf-life than their respective free bases. Amine hydrochlorides represent latent forms of a more reactive free base. In this regard, formation of an amine hydrochloride confers protection. This eff ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aromatic Nitriles
In chemistry, aromaticity is a chemical property of cyclic ( ring-shaped), ''typically'' planar (flat) molecular structures with pi bonds in resonance (those containing delocalized electrons) that gives increased stability compared to saturated compounds having single bonds, and other geometric or connective non-cyclic arrangements with the same set of atoms. Aromatic rings are very stable and do not break apart easily. Organic compounds that are not aromatic are classified as aliphatic compounds—they might be cyclic, but only aromatic rings have enhanced stability. The term ''aromaticity'' with this meaning is historically related to the concept of having an aroma, but is a distinct property from that meaning. Since the most common aromatic compounds are derivatives of benzene (an aromatic hydrocarbon common in petroleum and its distillates), the word ''aromatic'' occasionally refers informally to benzene derivatives, and so it was first defined. Nevertheless, many non- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indoles
Indole is an aromatic heterocyclic organic compound with the formula C8 H7 N. It has a bicyclic structure, consisting of a six-membered benzene ring fused to a five-membered pyrrole ring. Indole is widely distributed in the natural environment and can be produced by a variety of bacteria. As an intercellular signal molecule, indole regulates various aspects of bacterial physiology, including spore formation, plasmid stability, resistance to drugs, biofilm formation, and virulence. The amino acid tryptophan is an indole derivative and the precursor of the neurotransmitter serotonin. General properties and occurrence Indole is a solid at room temperature. It occurs naturally in human feces and has an intense fecal odor. At very low concentrations, however, it has a flowery smell, and is a constituent of many perfumes. It also occurs in coal tar. The corresponding substituent is called indolyl. Indole undergoes electrophilic substitution, mainly at position 3 (see diagram i ...

5-HT2A Antagonists
The 5-HT2A receptor is a subtype of the 5-HT2 receptor that belongs to the serotonin receptor family and is a G protein-coupled receptor (GPCR). The 5-HT2A receptor is a cell surface receptor, but has several intracellular locations. 5-HT is short for 5-hydroxy-tryptamine or serotonin. This is the main excitatory receptor subtype among the GPCRs for serotonin, although 5-HT2A may also have an inhibitory effect on certain areas such as the visual cortex and the orbitofrontal cortex. This receptor was first noted for its importance as a target of serotonergic psychedelic drugs such as LSD and psilocybin mushrooms. Later it came back to prominence because it was also found to be mediating, at least partly, the action of many antipsychotic drugs, especially the atypical ones. Downregulation of post-synaptic 5-HT2A receptor is an adaptive process provoked by chronic administration of selective serotonin reuptake inhibitors (SSRIs) and atypical antipsychotics. Suicidal and otherwise ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ziprasidone
Ziprasidone, sold under the brand name Geodon among others, is an atypical antipsychotic used to treat schizophrenia and bipolar disorder. It may be used by mouth and by injection into a muscle (IM). The IM form may be used for acute agitation in people with schizophrenia. Common side effects include dizziness, drowsiness, dry mouth, and twitches. Although it can also cause weight gain, the risk is much lower than for other atypical antipsychotics. How it works is not entirely clear but is believed to involve effects on serotonin and dopamine in the brain. Ziprasidone was approved for medical use in the United States in 2001. The pills are made up of the hydrochloride salt, ziprasidone hydrochloride. The intramuscular form is the mesylate, ziprasidone mesylate trihydrate, and is provided as a lyophilized powder. In 2020, it was the 282nd most commonly prescribed medication in the United States, with more than 1million prescriptions. Medical uses Ziprasidone is approved by ...

Pimavanserin
Pimavanserin (ACP-103; BVF-036), sold under the brand name Nuplazid, is an atypical antipsychotic which is approved for the treatment of Parkinson's disease psychosis and is also being studied for the treatment of Alzheimer’s disease psychosis, schizophrenia, agitation, and major depressive disorder. Unlike other antipsychotics, pimavanserin is not a dopamine receptor antagonist. Pharmacology Pharmacodynamics Pimavanserin acts as an inverse agonist and antagonist at serotonin 5-HT2A receptors with high binding affinity ( Ki 0.087 nM) and at serotonin 5-HT2C receptors with lower binding affinity (Ki 0.44 nM). Pimavanserin shows low binding to σ1 receptors (Ki 120 nM) and has no appreciable affinity (Ki >300 nM) to serotonin 5-HT2B, dopamine (including D2), muscarinic acetylcholine, histamine, or adrenergic receptors, or to calcium channels. Pimavanserin has a unique mechanism of action relative to other antipsychotics, behaving as a selective inv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
