Femoxetine
Femoxetine (INN; tentative brand name Malexil; developmental code name FG-4963) is a drug related to paroxetine that was being developed as an antidepressant by Danish pharmaceutical company Ferrosan in 1975 before acquisition of the company by Novo Nordisk. It acts as a selective serotonin reuptake inhibitor (SSRI). Development was halted to focus attention on paroxetine instead, as femoxetine could not be administered as a daily pill. Both femoxetine and paroxetine were invented in the 1970s. Jørgen Anders Christensen's name is on the patents and Jorgen Buus-Lassen's name is on the pharmacology paper. After Ferrosan's acquisition, femoxetine died from neglect. In a separate patent, Ferrosan stated that Femoxetine could be used as an appetite suppressant, using ten times the dosage than for paroxetine, 300 - 400mg daily. Femoxetine has the same stereochemical properties as Nocaine, another agent with a similar structure claimed to have been synthesized using arecoline as t ...

Nocaine
(+)-CPCA (nocaine, 3α-carbomethoxy-4β-(4-chlorophenyl)-''N''-methylpiperidine aka CTDP 31,446 ) is a stimulant drug similar in structure to pethidine (an opioid that possesses NDRI actions) and to RTI-31, but nocaine is lacking the two-carbon bridge of RTI-31's tropane skeleton. This compound was first developed as a substitute agent for cocaine. Since this time many substituted phenylpiperidine derivatives have been discovered, hybridizing the basic nocaine structure with that of other similar molecules such as methylphenidate, meperidine and modafinil to create a large family of derivatives with a range of activity profiles and potential applications. This is a significant field of research with much work ongoing, and dozens of novel compounds have been developed although none have yet come to market. The nocaine family includes a diverse assortment of piperidine based cocaine mimics. The parent compound nocaine was developed in an attempt to develop a substitute drug fo ...

Selective Serotonin Reuptake Inhibitor
Selective serotonin reuptake inhibitors (SSRIs) are a class of drugs that are typically used as antidepressants in the treatment of major depressive disorder, anxiety disorders, and other psychological conditions. SSRIs increase the extracellular level of the neurotransmitter serotonin by limiting its reabsorption (reuptake) into the presynaptic cell. They have varying degrees of selectivity for the other monoamine transporters, with pure SSRIs having strong affinity for the serotonin transporter and only weak affinity for the norepinephrine and dopamine transporters. SSRIs are the most widely prescribed antidepressants in many countries. The efficacy of SSRIs in mild or moderate cases of depression has been disputed and may or may not be outweighed by side effects, especially in adolescent populations. Medical uses The main indication for SSRIs is major depressive disorder; however, they are frequently prescribed for anxiety disorders, such as social anxiety disorder, ge ...

Serotonin Transporter
The serotonin transporter (SERT or 5-HTT) also known as the sodium-dependent serotonin transporter and solute carrier family 6 member 4 is a protein that in humans is encoded by the SLC6A4 gene. SERT is a type of monoamine transporter protein that transports the neurotransmitter serotonin from the synaptic cleft back to the presynaptic neuron, in a process known as serotonin reuptake. This transport of serotonin by the SERT protein terminates the action of serotonin and recycles it in a sodium-dependent manner. Many antidepressant medications of the SSRI and tricyclic antidepressant classes work by binding to SERT and thus reducing serotonin reuptake. It is a member of the sodium:neurotransmitter symporter family. A repeat length polymorphism in the promoter of this gene has been shown to affect the rate of serotonin uptake and may play a role in sudden infant death syndrome, aggressive behavior in Alzheimer disease patients, post-traumatic stress disorder and depression-suscepti ...

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 phenol to ...

Muscarinic Antagonists
A muscarinic receptor antagonist (MRA) is a type of anticholinergic agent that blocks the activity of the muscarinic acetylcholine receptor. The muscarinic receptor is a protein involved in the transmission of signals through certain parts of the nervous system, and muscarinic receptor antagonists work to prevent this transmission from occurring. Notably, muscarinic antagonists reduce the activation of the parasympathetic nervous system. The normal function of the parasympathetic system is often summarised as "rest-and-digest", and includes slowing of the heart, an increased rate of digestion, narrowing of the airways, promotion of urination, and sexual arousal. Muscarinic antagonists counter this parasympathetic "rest-and-digest" response, and also work elsewhere in both the central and peripheral nervous systems. Drugs with muscarinic antagonist activity are widely used in medicine, in the treatment of low heart rate, overactive bladder, respiratory problems such as asthma and ...

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] |
Zimelidine
Zimelidine (INN, BAN) (brand names Zimeldine, Normud, Zelmid) was one of the first selective serotonin reuptake inhibitor (SSRI) antidepressants to be marketed. It is a pyridylallylamine, and is structurally different from other antidepressants. Zimelidine was developed in the late 1970s and early 1980s by Arvid Carlsson, who was then working for the Swedish company Astra AB. It was discovered following a search for drugs with structures similar to brompheniramine (it is a derivative of brompheniramine), an antihistamine with antidepressant activity. Zimelidine was first sold in 1982. While zimelidine had a very favorable safety profile, within a year and a half of its introduction, rare case reports of Guillain–Barré syndrome emerged that appeared to be caused by the drug, prompting its manufacturer to withdraw it from the market. After its withdrawal, it was succeeded by fluvoxamine and fluoxetine (derived from the antihistamine diphenhydramine) in that order, and the o ...

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] |
Alaproclate
Alaproclate (developmental code name GEA-654) is a drug that was being developed as an antidepressant by the Swedish pharmaceutical company Astra AB (now AstraZeneca) in the 1970s. It acts as a selective serotonin reuptake inhibitor (SSRI), and along with zimelidine and indalpine, was one of the first of its kind. Development was discontinued due to the observation of liver complications in rodent studies. In addition to its SSRI properties, alaproclate has been found to act as a non-competitive NMDA receptor antagonist, but does not have discriminative stimulus properties similar to phencyclidine.

Viloxazine
Viloxazine, sold under the brand name Qelbree and formerly as Vivalan among others, is a noradrenergic medication which is used in the treatment of attention deficit hyperactivity disorder (ADHD) in children and adults. It was marketed for almost 30years as an antidepressant for the treatment of depression before being discontinued and subsequently repurposed as a treatment for ADHD. Viloxazine is taken by mouth. It was used as an antidepressant in an immediate-release form and is used in ADHD in an extended-release form. Side effects of viloxazine include insomnia, headache, somnolence, fatigue (medical), fatigue, nausea, vomiting, decreased appetite, dry mouth, constipation, irritability, increased heart rate, and increased blood pressure. Rarely, the medication may cause suicidal ideation, suicidal thoughts and suicidal behavior, behaviors. It can also activate mania or hypomania in people with bipolar disorder.

ORL1
The nociceptin opioid peptide receptor (NOP), also known as the nociceptin/orphanin FQ (N/OFQ) receptor or kappa-type 3 opioid receptor, is a protein that in humans is encoded by the ''OPRL1'' (opioid receptor-like 1) gene. The nociceptin receptor is a member of the opioid subfamily of G protein-coupled receptors whose natural ligand is the 17 amino acid neuropeptide known as nociceptin (N/OFQ). This receptor is involved in the regulation of numerous brain activities, particularly instinctive and emotional behaviors. Antagonists targeting NOP are under investigation for their role as treatments for depression and Parkinson's disease, whereas NOP agonists have been shown to act as powerful, non-addictive painkillers in non-human primates. Although NOP shares high sequence identity (~60%) with the ‘classical’ opioid receptors μ-OP (MOP), κ-OP (KOP), and δ-OP (DOP), it possesses little or no affinity for opioid peptides or morphine-like compounds. Likewise, classical opioid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
