Clofuperol
Clofluperol is a neuroleptic tranquilizer of the butyrophenone class. It has the same aromatic piperidinol moiety that is present in penfluridol and fluperamide. The structure can be seen to be a sort of hybrid between that of trifluperidol and haloperidol Haloperidol, sold under the brand name Haldol among others, is a typical antipsychotic medication. Haloperidol is used in the treatment of schizophrenia, tics in Tourette syndrome, mania in bipolar disorder, delirium, agitation, acute psychos ....

Penfluridol
Penfluridol (Semap, Micefal, Longoperidol) is a highly potent, first generation diphenylbutylpiperidine antipsychotic. It was discovered at Janssen Pharmaceutica in 1968. Related to other diphenylbutylpiperidine antipsychotics, pimozide and fluspirilene, penfluridol has an extremely long elimination half-life and its effects last for many days after single oral dose. Its antipsychotic potency, in terms of dose needed to produce comparable effects, is similar to both haloperidol and pimozide. It is only slightly sedative, but often causes extrapyramidal symptoms, extrapyramidal side-effects, such as akathisia, dyskinesiae and pseudo-Parkinsonism. Penfluridol is indicated for antipsychotic treatment of chronic schizophrenia and similar psychosis, psychotic disorders, it is, however, like most typical antipsychotics, being increasingly replaced by the atypical antipsychotics. Due to its extremely long-lasting effects, it is often prescribed to be taken orally as tablets only once a we ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fluperamide
Fluperamide is a synthetic opioid structurally related to loperamide, developed as a potent antidiarrheal agent. Like loperamide, it acts primarily as a peripherally selective μ-opioid receptor agonist, effectively reducing gastrointestinal motility and fluid secretion without significant central nervous system effects due to limited blood-brain barrier penetration. Fluperamide’s pharmacological profile was designed to maximize antidiarrheal efficacy while minimizing the risk of opioid-related side effects and abuse potential, a strategy that has contributed to the development of related compounds in the phenylpiperidine class. Although fluperamide demonstrated strong antidiarrheal activity in preclinical and early clinical studies, it was ultimately not commercialized, with loperamide becoming the preferred agent in this therapeutic category due to its favorable safety and efficacy.

Neuroleptic
Antipsychotics, previously known as neuroleptics and major tranquilizers, are a class of psychotropic medication primarily used to manage psychosis (including delusions, hallucinations, paranoia or disordered thought), principally in schizophrenia but also in a range of other psychotic disorders. They are also the mainstay, together with mood stabilizers, in the treatment of bipolar disorder. Moreover, they are also used as adjuncts in the treatment of treatment-resistant major depressive disorder. The use of antipsychotics may result in many unwanted side effects such as involuntary movement disorders, gynecomastia, impotence, weight gain and metabolic syndrome. Long-term use can produce adverse effects such as tardive dyskinesia, tardive dystonia, tardive akathisia, and brain tissue volume reduction. The long term use of antipsychotics often changes the brain both structurally and chemically in a way that can be difficult or impossible to reverse. This can lead to lo ...

Tranquilizer
A sedative or tranquilliser is a substance that induces sedation by reducing irritability or excitement. They are central nervous system (CNS) depressants and interact with brain activity, causing its deceleration. Various kinds of sedatives can be distinguished, but the majority of them affect the neurotransmitter gamma-aminobutyric acid (GABA). Most sedatives produce relaxing effects by increasing GABA activity. This group is related to hypnotics. The term ''sedative'' describes drugs that serve to calm or relieve anxiety, whereas the term ''hypnotic'' describes drugs whose main purpose is to initiate, sustain, or lengthen sleep. Because these two functions frequently overlap, and because drugs in this class generally produce dose-dependent effects (ranging from anxiolysis to loss of consciousness), they are often referred to collectively as ''sedative–hypnotic'' drugs. Terminology There is some overlap between the terms "sedative" and "hypnotic". Advances in pharmacolo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Butyrophenone
Butyrophenone is an organic compound with the formula C6H5C(O)C3H7. It is a colorless liquid. The butyrophenone structure—a ketone flanked by a phenyl ring and a butyl chain—forms the basis for many other chemicals containing various substituents. Some of these butyrophenones are used to treat various psychiatric disorders such as schizophrenia, as well as acting as antiemetics. Examples of butyrophenone-derived pharmaceuticals include: * Benperidol‡‡ denotes drugs that are no longer (or were never to begin with) marketed in the United States. Some antipsychotics are not firmly placed in either first-generation or second-generation classes. (200 times more potent than chlorpromazine) * Bromperidol††indicates drugs that are no longer (or were never) marketed in English-speaking countries. * Droperidol‡, Antiemetic for postoperative nausea and vomiting * Haloperidol, the most widely used classical antipsychotic drug in this class * Lumateperone, an atypical ant ...

Trifluperidol
Trifluperidol is a typical antipsychotic of the butyrophenone chemical class. It has general properties similar to those of haloperidol, but is considerably more potent by weight, and causes relatively more severe side effects, especially tardive dyskinesia and other extrapyramidal effects. It is used in the treatment of psychoses including mania and schizophrenia. It was discovered at Janssen Pharmaceutica in 1959. Synthesis The Grignard reaction between 1-benzyl-4-piperidone 612-20-2(1) and 3-bromobenzotrifluoride 01-78-5(2) gives 1-benzyl-4-(3-(trifluoromethyl)phenyl)piperidin-4-olCID:12718203(3). 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.

Haloperidol
Haloperidol, sold under the brand name Haldol among others, is a typical antipsychotic medication. Haloperidol is used in the treatment of schizophrenia, tics in Tourette syndrome, mania in bipolar disorder, delirium, agitation, acute psychosis, and hallucinations from alcohol withdrawal. It may be used by mouth or injection into a muscle or a vein. Haloperidol typically works within 30 to 60 minutes. A long-acting formulation may be used as an injection every four weeks for people with schizophrenia or related illnesses, who either forget or refuse to take the medication by mouth. Haloperidol may result in movement disorders such as tardive dyskinesia, and akathisia, both of which may be permanent. Neuroleptic malignant syndrome and QT interval prolongation may occur, the latter particularly with IV administration. In older people with psychosis due to dementia it results in an increased risk of death. When taken during pregnancy it may result in problems in the infant. I ...

Tertiary Alcohols
In chemistry, an alcohol (), is a type of organic compound that carries at least one hydroxyl () functional group bound to a Saturated and unsaturated compounds, saturated carbon atom. Alcohols range from the simple, like methanol and ethanol, to complex, like sugar alcohols and cholesterol. The presence of an OH group strongly modifies the properties of Hydrocarbon, hydrocarbons, conferring Hydrophile, hydrophilic (water-loving) properties. The OH group provides a site at which many reactions can occur. History The flammable nature of the exhalations of wine was already known to ancient natural philosophers such as Aristotle (384–322 BCE), Theophrastus (–287 BCE), and Pliny the Elder (23/24–79 CE). However, this did not immediately lead to the isolation of alcohol, even despite the development of more advanced distillation techniques in second- and third-century Roman Egypt. An important recognition, first found in one of the writings attributed to Jabir ibn Hayyan, JÄ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The informal use of the term ''formula'' in science refers to the general construct of a relationship betwe ... . The naming of is group is derived from the methyl group (which has the formula ), by replacing each hydrogen atom by a fluorine atom. Some common examples are trifluoromethane , 1,1,1-trifluoroethane , and hexafluoroacetone . Compounds with this group are a subclass of the organofluorines. Properties The trifluoromethyl group has a significant electronegativity that is often described as being intermediate between the electronegativities of fluorine and chlorine. For this reason, trifluoromethyl-substituted compounds are often strong acids, such as trifluoromethanesulfonic acid and trifluoroacetic acid. Conversely, the trifluoromethyl group lowers the basicity of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Typical Antipsychotics
Typical antipsychotics (also known as major tranquilizers, and first generation antipsychotics) are a class of antipsychotic drugs first developed in the 1950s and used to treat psychosis (in particular, schizophrenia). Typical antipsychotics may also be used for the treatment of acute mania, agitation, and other conditions. The first typical antipsychotics to come into medical use were the phenothiazines, namely chlorpromazine which was discovered serendipitously. Another prominent grouping of antipsychotics are the butyrophenones, an example of which is haloperidol. The newer, second-generation antipsychotics, also known as atypical antipsychotics, have largely supplanted the use of typical antipsychotics as first-line agents due to the higher risk of movement disorders with typical antipsychotics. Both generations of medication tend to block receptors in the brain's dopamine pathways, but atypicals at the time of marketing were claimed to differ from typical antipsychoti ...
