Benzylbutylbarbiturate
Benzylbutylbarbiturate (5-benzyl-5-''n''-butylbarbituric acid) is a rare example of a barbiturate designer drug, possibly the only such compound encountered in recent years. It was confiscated by police in Japan in 2000, and presumably was a product of clandestine manufacture as this compound has never previously been sold as a legal pharmaceutical. As with all designer drugs, this compound was produced in an attempt to circumvent drug laws prohibiting the use of most known barbiturate drugs, however as the drug laws in many jurisdictions (including Japan) prohibit "any 5,5-disubstituted derivative of barbituric acid", this compound was deemed to be already illegal, despite being a novel compound which had not previously been encountered. This compound was known from the scientific literature and so was not a new chemical entity A new chemical entity (NCE) is, according to the U.S. Food and Drug Administration, a novel, small, chemical molecule drug that is undergoing clinical tr ...

Barbiturate
Barbiturates are a class of depressant drugs that are chemically derived from barbituric acid. They are effective when used medically as anxiolytics, hypnotics, and anticonvulsants, but have physical and psychological addiction potential as well as overdose potential among other possible adverse effects. They have been used recreationally for their anxiolytic and sedative effects, and are thus controlled in most countries due to the risks associated with such use. Barbiturates have largely been replaced by benzodiazepines and nonbenzodiazepines ("Z-drugs") in routine medical practice, particularly in the treatment of anxiety disorders and insomnia, because of the significantly lower risk of overdose, and the lack of an antidote for barbiturate overdose. Despite this, barbiturates are still in use for various purposes: in general anesthesia, epilepsy, treatment of acute migraines or cluster headaches, acute tension headaches, euthanasia, capital punishment, and assisted suicid ...

Designer Drug
A designer drug is a structural or functional analog of a controlled substance that has been designed to mimic the pharmacological effects of the original drug, while avoiding classification as illegal and/or detection in standard drug tests. Designer drugs include psychoactive substances that have been designated by the European Union as new psychoactive substances (NPS) as well as analogs of performance-enhancing drugs such as designer steroids. Some of these were originally synthesized by academic or industrial researchers in an effort to discover more potent derivatives with fewer side effects, and shorter duration (and possibly also because it is easier to apply for patents for new molecules) and were later co-opted for recreational use. Other designer drugs were prepared for the first time in clandestine laboratories. Because the efficacy and safety of these substances have not been thoroughly evaluated in animal and human trials, the use of some of these drugs may result i ...

New Chemical Entity
A new chemical entity (NCE) is, according to the U.S. Food and Drug Administration, a novel, small, chemical molecule drug that is undergoing clinical trials or has received a first approval (not a new use) by the FDA in any other application submitted under section 505(b) of the Federal Food, Drug, and Cosmetic Act. A new molecular entity (NME) is a broader term that emcompasses both an NCE or an NBE (New Biological Entity). Definition An active moiety is a molecule or ion, excluding those appended portions of the molecule that cause the drug to be an ester, salt (including a salt with hydrogen or coordination bonds), or other noncovalent derivative (such as a complex, chelate, or clathrate) of the molecule, responsible for the physiological or pharmacological action of the drug substance. An NCE is a molecule developed by the innovator company in the early drug discovery stage, which after undergoing clinical trials could translate into a drug that could be a treatment for some ...

GABAA Receptor Positive Allosteric Modulators
In pharmacology, GABAA receptor positive allosteric modulators are positive allosteric modulator (PAM) molecules that increase the activity of the GABAA receptor protein in the vertebrate central nervous system. GABA is a major inhibitory neurotransmitter in the central nervous system. Upon binding, it triggers the GABAA receptor to open its chloride channel to allow chloride ions into the neuron, making the cell hyperpolarized and less likely to fire. GABAA PAMs increase the effect of GABA by making the channel open more frequently or for longer periods. However, they have no effect if GABA or another agonist is not present. Unlike GABAA receptor agonists, GABAA PAMs do not bind at the same active site as the γ-Aminobutyric acid (GABA) neurotransmitter molecule: they affect the receptor by binding at a different site on the protein. This is called allosteric modulation. In psychopharmacology, GABAA receptor PAMs used as drugs have mainly sedative and anxiolytic effects. ...
