Tesofensine
Tesofensine (NS2330) is a serotonin-noradrenaline-dopamine reuptake inhibitor, serotonin–noradrenaline–dopamine reuptake inhibitor from the phenyltropane family of drugs, which is being developed for the treatment of obesity. Tesofensine was originally developed by a Danish biotechnology company, NeuroSearch, who transferred the rights to Saniona in 2014. As of 2019, tesofensine has been discontinued for the treatment of Alzheimer's and Parkinson's disease but is in Phases of clinical research, phase III clinical trial for obesity. History Tesofensine was originally investigated for the treatment of Alzheimer's disease and Parkinson's disease, and was subsequently dropped from development for these applications after early trial results showed limited efficacy for treatment of these diseases. However, weight loss was consistently reported as an adverse event in the original studies, especially in overweight or Obesity, obese patients. Therefore, it was decided to pursue d ...

Dopamine Transporter
The dopamine transporter (DAT, also sodium-dependent dopamine transporter) is a membrane-spanning protein coded for in humans by the ''SLC6A3'' gene (also known as ''DAT1''), that pumps the neurotransmitter dopamine out of the synaptic cleft back into cytosol. In the cytosol, other transporters sequester the dopamine into Vesicle (biology and chemistry), vesicles for storage and later release. Dopamine reuptake via DAT provides the primary mechanism through which dopamine is cleared from synapses, although there may be an exception in the prefrontal cortex, where evidence points to a possibly larger role of the norepinephrine transporter. DAT is implicated in a number of dopamine-related disorders, including ADHD, attention deficit hyperactivity disorder, bipolar disorder, clinical depression, eating disorders, and substance use disorders. The gene that encodes the DAT protein is located on chromosome 5, consists of 15 coding exons, and is roughly 64 base pair#Length measuremen ...

Cholinergic
Cholinergic agents are compounds which mimic the action of acetylcholine and/or butyrylcholine. In general, the word " choline" describes the various quaternary ammonium salts containing the ''N'',''N'',''N''-trimethylethanolammonium cation. Found in most animal tissues, choline is a primary component of the neurotransmitter acetylcholine and functions with inositol as a basic constituent of lecithin. Choline also prevents fat deposits in the liver and facilitates the movement of fats into cells. The parasympathetic nervous system, which uses acetylcholine almost exclusively to send its messages, is said to be almost entirely cholinergic. Neuromuscular junctions, preganglionic neurons of the sympathetic nervous system, the basal forebrain, and brain stem complexes are also cholinergic, as are the receptor for the merocrine sweat glands. In neuroscience and related fields, the term cholinergic is used in these related contexts: * A substance (or ligand) is cholinergic if ...

Experimental Anti-obesity Drugs
An experiment is a procedure carried out to support or refute a hypothesis, or determine the efficacy or likelihood of something previously untried. Experiments provide insight into cause-and-effect by demonstrating what outcome occurs when a particular factor is manipulated. Experiments vary greatly in goal and scale but always rely on repeatable procedure and logical analysis of the results. There also exist natural experimental studies. A child may carry out basic experiments to understand how things fall to the ground, while teams of scientists may take years of systematic investigation to advance their understanding of a phenomenon. Experiments and other types of hands-on activities are very important to student learning in the science classroom. Experiments can raise test scores and help a student become more engaged and interested in the material they are learning, especially when used over time. Experiments can vary from personal and informal natural comparisons (e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anorectics
An anorectic is a drug that reduces appetite, resulting in lower food consumption, leading to weight loss. These substances work by affecting the central nervous system or certain neurotransmitters to create a feeling of fullness or reduce the desire to eat. The understanding of anorexiant effects is crucial in the development of interventions for weight management, eating disorders, and related health concerns. The anorexiant effect can be induced through diverse mechanisms, ranging from hormonal regulation to neural signaling. Ghrelin, leptin, and peptide YY are among the hormones involved in appetite control. Additionally, neurotransmitters such as serotonin and dopamine in the central nervous system contribute significantly to the regulation of food intake. By contrast, an appetite stimulant is referred to as orexigenic. The term is (from the Greek and ), and such drugs are also known as anorexigenic, anorexiant, or appetite suppressant.

Dexanabinol
Dexanabinol (HU-211 or ETS2101) is a synthetic cannabinoid derivative in development by e-Therapeutics plc. It is the "unnatural" enantiomer of the potent cannabinoid agonist HU-210. Unlike other cannabinoid derivatives, HU-211 does not act as a cannabinoid receptor agonist, but instead as an NMDA antagonist. It therefore does not produce cannabis-like effects, but is anticonvulsant and neuroprotective, and is widely used in scientific research as well as currently being studied for applications such as treating head injury, stroke, or cancer. It was shown to be safe in clinical trials and is currently undergoing Phase I trials for the treatment of brain cancer and advanced solid tumors. Clinical trials Dexanabinol has been studied in IV administration and oral dosing. e-Therapeutics is evaluating the compound in clinical trials for brain and solid cancers. Phase II studies are planned based on the results of the current trials. A phase 1b study for hepatocellular carcin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indatraline
Indatraline hydrochloride (Lu 19-005) is an antidepressive agent and non-selective monoamine transporter inhibitor that blocks the reuptake of dopamine, norepinephrine, and serotonin with similar efficacy to cocaine. This compound may be used to treat cocaine addictions as its effects have a slower onset and a longer duration than those of cocaine. Indatraline has been shown to block the action of methamphetamine and MDMA in laboratory experiments. Methylation Indatraline is ''N''-alkylated at the amino group, making it possible to slow the onset of action, so that it is not until ''N''-demethylation occurs that the molecules become active. ''N''-methylindatraline has a longer duration than indatraline because norindatraline is inactive, whereas demethylating ''N''-methylindatraline does not terminate the actions of the parent compound. Effects of ''N''-dimethylindatraline start about 20–30 minutes after administration; it takes a longer time for this chemical to absorb into ...

Phencyclidine
Phencyclidine or phenylcyclohexyl piperidine (PCP), also known in its use as a street drug as angel dust among other names, is a dissociative anesthetic mainly used recreationally for its significant mind-altering effects. PCP may cause hallucinations, distorted perceptions of sounds, and psychotic behavior. As a recreational drug, it is typically smoked, but may be taken by mouth, snorted, or injected. It may also be mixed with cannabis or tobacco. Adverse effects may include paranoia, addiction, and an increased risk of suicide, as well as seizures and coma in cases of overdose. Flashbacks may occur despite stopping usage. Chemically, PCP is a member of the arylcyclohexylamine class. PCP works primarily as an NMDA receptor antagonist. PCP is most commonly used in the US. While usage peaked in the US in the 1970s, between 2005 and 2011, an increase in visits to emergency departments as a result of the drug occurred. As of 2022, in the US, about 0.7% of 12th-grade ...

Hyperforin
Hyperforin is a phytochemical produced by some of the members of the plant genus ''Hypericum'', notably ''Hypericum perforatum'' (St John's wort). Hyperforin may be involved in the pharmacology, pharmacological effects of St. John's wort, specifically in its antidepressant effects. Meta-analysis, Meta-analyses of Clinical trial, clinical trials suggest that ''H. perforatum'' is as effective as Selective serotonin reuptake inhibitor, SSRIs for treating mild to moderate Depression (mood), depression and is better tolerated, although findings are limited by short study durations. Hyperforin is found in significant amounts only in ''H. perforatum'', where it accumulates as a probable Plant defense against herbivory, plant defense compound, with modern Carbon dioxide, CO₂ extraction methods used to isolate it from mixtures containing related compounds like adhyperforin. Occurrence Hyperforin has only been found in significant amounts in ''Hypericum perforatum'' with other related s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Open-label Trial
An open-label trial, or open trial, is a type of clinical trial in which information is not withheld from trial participants. In particular, both the researchers and participants know which treatment is being administered. This contrasts with a double-blinded trial, where information is withheld both from the researchers and the participants to reduce bias. Open-label trials may be appropriate for comparing two similar treatments to determine which is most effective, such as a comparison of different prescription anticoagulants, or possible relief from symptoms of some disorders when a placebo is given. An open-label trial may still be randomized. Open-label trials may also be uncontrolled (without a placebo group), with all participants receiving the same treatment.

Placebo-controlled Studies
Placebo-controlled studies are a way of testing a medical therapy in which, in addition to a group of subjects that receives the treatment to be evaluated, a separate control group receives a sham "placebo" treatment which is specifically designed to have no real effect. Placebos are most commonly used in blinded trials, where subjects do not know whether they are receiving real or placebo treatment. Often, there is also a further "natural history" group that does not receive any treatment at all. The purpose of the placebo group is to account for the placebo effect, that is, effects from treatment that do not depend on the treatment itself. Such factors include knowing one is receiving a treatment, attention from health care professionals, and the expectations of a treatment's effectiveness by those running the research study. Without a placebo group to compare against, it is not possible to know whether the treatment itself had any effect. Patients frequently show improvement ...
