Tesofensine
Tesofensine (NS2330) is a 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 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 obese patients. Therefore, it was decided to pursue development of tesofensine for the treatment of obesity. Tesofensine primarily acts as an ...

Antiobesity Drugs
Anti-obesity medication or weight loss medications are pharmacological agents that reduce or control weight. These medications alter one of the fundamental processes of the human body, weight regulation, by altering either appetite, or absorption of calories. The main treatment modalities for overweight and individuals with obesity remain dieting (healthy diet and caloric restriction) and physical exercise. In the United States orlistat (Xenical) and semaglutide (Wegovy) are currently approved by the FDA for long-term use. Xenical reduces intestinal fat absorption by inhibiting pancreatic lipase; Wegovy is a GLP-1 analogue, a class of drugs that is relatively recent and which has promise as an effective anti-obesity measure. Because of potential side effects, and limited evidence of small benefits in weight reduction for children and adolescents with obesity, it is recommended that anti-obesity medications only be prescribed for obesity where it is hoped that the benefits of ...

Neurotransmission
Neurotransmission (Latin: ''transmissio'' "passage, crossing" from ''transmittere'' "send, let through") is the process by which signaling molecules called neurotransmitters are released by the axon terminal of a neuron (the presynaptic neuron), and bind to and react with the receptors on the dendrites of another neuron (the postsynaptic neuron) a short distance away. A similar process occurs in retrograde neurotransmission, where the dendrites of the postsynaptic neuron release retrograde neurotransmitters (e.g., endocannabinoids; synthesized in response to a rise in intracellular calcium levels) that signal through receptors that are located on the axon terminal of the presynaptic neuron, mainly at GABAergic and glutamatergic synapses. Neurotransmission is regulated by several different factors: the availability and rate-of-synthesis of the neurotransmitter, the release of that neurotransmitter, the baseline activity of the postsynaptic cell, the number of available postsynapti ...

Anorectics
An anorectic or anorexic is a drug which reduces appetite, resulting in lower food consumption, leading to weight loss. By contrast, an appetite stimulant is referred to as orexigenic. The term is (from the Greek ''ἀν-'' (an-) = "without" and ''ὄρεξις'' (órexis) = "appetite"), and such drugs are also known as anorexigenic, anorexiant, or appetite suppressant. History Used on a short-term basis clinically to treat obesity, some appetite suppressants are also available over-the-counter. Most common natural appetite suppressants are based on ''Hoodia'', a genus of 13 species in the flowering plant family Apocynaceae, under the subfamily Asclepiadoideae. Several appetite suppressants are based on a mix of natural ingredients, mostly using green tea as its basis, in combination with other plant extracts such as fucoxanthin, found naturally in seaweed. Drugs of this class are frequently stimulants of the phenethylamine family, related to amphetamine. The German and Finnish ...

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 has NMDA antagonist effects. 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 carci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indatraline
Indatraline (Lu 19-005) is a non- selective monoamine transporter inhibitor shown to block the reuptake of dopamine, norepinephrine, and serotonin, with effects similar to those of cocaine. The effects have been shown to have a slower onset and longer duration than cocaine, suggesting that the compound may, along with similar compounds, be used for the treatment of cocaine addiction. LU 19-005 has been shown to block the action of methamphetamine and MDMA in laboratory experiments. Superposition should make it possible to see there is at least a fundamental relationship between the pharmacophore of indatraline and various phenyltropanes. Methylation If indatraline is ''N''-alkylated at the amino group, it is 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 much longer duration than indatraline because norindatraline is inactive, whereas demethylating ''N''-methylindatraline doe ...

Phencyclidine
Phencyclidine or phenylcyclohexyl piperidine (PCP), also known 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 violent 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 seizures, coma, addiction, and an increased risk of suicide. Flashbacks may occur despite stopping usage. Chemically, PCP is a member of the arylcyclohexylamine class, and pharmacologically, it is a dissociative anesthetic. PCP works primarily as an NMDA receptor antagonist. PCP is most commonly used in the United States. 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 2017 in the United States, about 1% of people in Twelfth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 pharmacological effects of St. John's wort, specifically in its antidepressant effects. Occurrence Hyperforin has only been found in significant amounts in ''Hypericum perforatum'' with other related species such as '' Hypericum calycinum'' containing lower levels of the phytochemical. It accumulates in oil glands, pistils, and fruits, probably as a plant defensive compound. The first natural extractions were done with ethanol and afforded a 7:1 yield of crude extract to phytochemical however, this technique produced a mixture of hyperforin and adhyperforin. The extraction technique has since been modernized using lipophilic liquid CO2 extraction to afford a 3:1 crude to phytochemical extraction which is then further purified away from adhyperforin. This CO2 extraction is rather tricky still because t ... [...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 Clinical trials are prospective biomedical or behavioral research studies on human participants designed to answer specific questions about biomedical or behavioral interventions, including new treatments (such as novel vaccines, drugs, dieta ...), with all parti ...

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 e ...
