Indeloxazine
Indeloxazine ( INN; trade names Elen and Noin) is an antidepressant and cerebral activator that was marketed in Japan and South Korea by Yamanouchi Pharmaceutical Co., Ltd for the treatment of psychiatric symptoms associated with cerebrovascular diseases, namely depression resulting from stroke, emotional disturbance, and avolition. It was marketed from 1988 to 1998, when it was removed from the market reportedly for lack of effectiveness. Indeloxazine acts as a serotonin releasing agent, norepinephrine reuptake inhibitor, and NMDA receptor antagonist. It has been found to enhance acetylcholine release in the rat forebrain through activation of the 5-HT4 receptor via its action as a serotonin releasing agent. The drug has been found to possess nootropic, neuroprotective, anticonvulsant, and antidepressant-like effects in animal model An animal model (short for animal disease model) is a living, non-human, often genetic-engineered animal used during the research and inves ...

Serotonin Releasing Agent
A serotonin releasing agent (SRA) is a type of drug that induces the release of serotonin into the neuronal synaptic cleft. A selective serotonin releasing agent (SSRA) is an SRA with less significant or no efficacy in producing neurotransmitter efflux at other types of monoamine neurons, including dopamine and norepinephrine neurons. SRAs, for instance fenfluramine, dexfenfluramine, and chlorphentermine, have been used clinically as appetite suppressants. However, these SRAs were withdrawn from the market due to toxicity in the 1990s and no SRAs were available or employable for clinical study for many years. In any case, a low-dose formulation was reintroduced for treatment of Dravet syndrome in 2020 and this allowed clinical and research use of SRAs in humans once again. Aside from use as appetite suppressants, SSRAs have been proposed as novel antidepressants and anxiolytics, with the potential for a faster onset of action and superior effectiveness relative to the selectiv ...

Norepinephrine Reuptake Inhibitors
A norepinephrine reuptake inhibitor (NRI, NERI) or noradrenaline reuptake inhibitor or adrenergic reuptake inhibitor (ARI), is a type of drug that acts as a reuptake inhibitor for the neurotransmitters norepinephrine (noradrenaline) and epinephrine (adrenaline) by blocking the drug action, action of the norepinephrine transporter (NET). This in turn leads to increased extracellular concentrations of norepinephrine and epinephrine and therefore can increase adrenergic neurotransmission. Medical use NRIs are commonly used in the treatment of conditions like attention-deficit hyperactivity disorder, ADHD and narcolepsy due to their psychostimulant effects and in obesity due to their appetite suppressant effects. They are also frequently used as antidepressants for the treatment of major depressive disorder, Anxiety Disorder, anxiety and panic disorder. Additionally, many substance use disorder, addictive substances such as cocaine and methylphenidate possess NRI activity, though ...

Nootropics
Nootropics ( or ) (colloquially brain supplements, smart drugs, cognitive enhancers, memory enhancers, or brain boosters) are chemical substances which purportedly improve cognitive functions, such as attention, memory, wakefulness, and self-control. In the United States, nootropics can be over-the-counter drugs and commonly advertised with unproven claims of effectiveness for improving cognition. The Federal Trade Commission and FDA have warned manufacturers and consumers about possible advertising fraud and marketing scams concerning nootropic supplements. Nootropics include both prescription drugs and dietary supplements marketed to enhance brain function, but while FDA-approved drugs have proven benefits and oversight, many dietary supplements lack evidence, may contain unapproved or hidden drugs, and pose safety and regulatory risks.Nootropics: Drugs vs Dietary Supplements for Brain Health.

NMDA Receptor Antagonists
NMDA receptor antagonists are a class of drugs that work to antagonize, or inhibit the action of, the ''N''-Methyl-D-aspartate receptor ( NMDAR). They are commonly used as anesthetics for humans and animals; the state of anesthesia they induce is referred to as dissociative anesthesia. Several synthetic opioids function additionally as NMDAR-antagonists, such as pethidine, levorphanol, methadone, dextropropoxyphene, tramadol, and ketobemidone. Some NMDA receptor antagonists, such as ketamine, dextromethorphan (DXM), phencyclidine (PCP), methoxetamine (MXE), and nitrous oxide (N2O), are sometimes used as recreational drugs, for their dissociative, hallucinogenic, and euphoriant properties. When used recreationally, they are classified as dissociative drugs. Uses and effects NMDA receptor antagonists induce a state called dissociative anesthesia, marked by catalepsy, amnesia, and analgesia. Ketamine is a favored anesthetic for emergency patients with unknown ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Morpholines
Morpholine is an organic chemical compound having the chemical formula O( C H2CH2)2 NH. This heterocycle features both amine and ether functional groups. Because of the amine, morpholine is a base; its conjugate acid is called morpholinium. For example, treating morpholine with hydrochloric acid generates the salt morpholinium chloride. It is a colorless liquid with a weak, ammonia- or fish-like odor. The naming of morpholine is attributed to Ludwig Knorr, who incorrectly believed it to be part of the structure of morphine. Production Morpholine is often produced industrially by the dehydration of diethanolamine with concentrated sulfuric acid. Alternatively, it can be made from bis(2-chloroethyl)ether in a reaction with ammonia, by which also ammonium chloride is formed. Morpholine is also produced industrially from diethylene glycol and ammonia, under high temperature and pressure, in the presence of hydrogen and a suitable catalyst. Uses Industrial applications Morpholin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indenes
Indene is an aromatic, polycyclic hydrocarbon with chemical formula . It is composed of a benzene ring fused with a cyclopentene ring. This flammable liquid is colorless although samples often are pale yellow. The principal industrial use of indene is in the production of indene/ coumarone thermoplastic resins. Substituted indenes and their closely related indane derivatives are important structural motifs found in many natural products and biologically active molecules, such as sulindac. Isolation Indene occurs naturally in coal-tar fractions boiling around 175–185 °C. It can be obtained by heating this fraction with sodium to precipitate solid "sodio-indene". This step exploits indene's weak acidity evidenced by its deprotonation by sodium to give the indenyl derivative. The sodio-indene is converted back to indene by steam distillation. Reactivity Indene readily polymerises. Oxidation of indene with acid dichromate yields homophthalic acid (''o''-carboxylphenyl ...

Animal Model
An animal model (short for animal disease model) is a living, non-human, often genetic-engineered animal used during the research and investigation of human disease, for the purpose of better understanding the disease process without the risk of harming a human. Although biological activity in an animal model does not ensure an effect in humans, many drugs, treatments and cures for human diseases are developed in part with the guidance of animal models. Animal models representing specific taxonomic groups in the research and study of developmental processes are also referred to as model organisms. There are three main types of animal models: Homologous, Isomorphic and Predictive. Homologous animals have the same causes, symptoms and treatment options as would humans who have the same disease. Isomorphic animals share the same symptoms and treatments, only. Predictive models are similar to a particular human disease in only a couple of aspects. However, these are useful in isolating ...

Anticonvulsant
Anticonvulsants (also known as antiepileptic drugs, antiseizure drugs, or anti-seizure medications (ASM)) are a diverse group of pharmacological agents used in the treatment of epileptic seizures. Anticonvulsants are also used in the treatment of bipolar disorder and borderline personality disorder, since many seem to act as mood stabilizers, and for the treatment of neuropathic pain. Anticonvulsants suppress the uncontrolled and excessive firing of neurons during seizures and in doing so can also prevent the spread of the seizure within the brain. Conventional antiepileptic drugs have diverse mechanisms of action but many block sodium channels or enhance γ-aminobutyric acid ( GABA) function. Several antiepileptic drugs have multiple or uncertain mechanisms of action. Next to voltage-gated sodium channels and components of the GABA system, their targets include GABAA receptors, the GABA transporter type 1, and GABA transaminase. Additional targets include voltage-gate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
