SL-164, also known as dicloqualone or DCQ, is an analogue of methaqualone developed in the late 1960s by a team at Sumitomo. [1] SL-164 has similar sedative, hypnotic and anticonvulsant properties to the parent compound, but was never marketed for clinical use. [2]

Thailand's Psychotropic Substances Act is a law designed to regulate certain mind-altering drugs. According to the Office of the Narcotics Control Board, "The Act directly resulted from the Convention on Psychotropic Substances 1971 of which Thailand is a party." The Act divides psychotropic drugs into four Schedules. Offenses involving Schedule I and II drugs carry heavier penalties than those involving Schedule III and IV drugs. Note that this statute does not regulate most opioids, cocaine, or some amphetamines. The vast majority of narcotic painkillers, along with cocaine and most amphetamines are regulated under the Narcotics Act.

<i>Controlled Drugs and Substances Act</i> Canadian federal drug regulation act

The Controlled Drugs and Substances Act is Canada's federal drug control statute. Passed in 1996 under Prime Minister Jean Chrétien's government, it repeals the Narcotic Control Act and Parts III and IV of the Food and Drugs Act, and establishes eight Schedules of controlled substances and two Classes of precursors. It provides that "The Governor in Council may, by order, amend any of Schedules I to VIII by adding to them or deleting from them any item or portion of an item, where the Governor in Council deems the amendment to be necessary in the public interest."

Quinazoline is an organic compound with the formula C8H6N2. It is an aromatic heterocycle with a bicyclic structure consisting of two fused six-membered aromatic rings, a benzene ring and a pyrimidine ring. It is a light yellow crystalline solid that is soluble in water. Also known as 1,3-diazanaphthalene, quinazoline received its name from being an aza derivative of quinoline. Though the parent quinazoline molecule is rarely mentioned by itself in technical literature, substituted derivatives have been synthesized for medicinal purposes such as antimalarial and anticancer agents. Quinazoline is a planar molecule. It is isomeric with the other diazanaphthalenes of the benzodiazine subgroup: cinnoline, quinoxaline, and phthalazine. Over 200 biologically active quinazoline and quinoline alkaloids are identified.

<span class="mw-page-title-main">Diproqualone</span> Chemical compound

Diproqualone is a quinazolinone class GABAergic and is an analogue of methaqualone developed in the late 1950s by a team at Nogentaise de Produits Chimique. It was marketed primarily in France and some other European countries. It has sedative, anxiolytic, antihistamine and analgesic properties, resulting from its agonist activity at the β subtype of the GABAa receptor, antagonist activity at all histamine receptors, inhibition of the cyclooxygenase-1 enzyme, and possibly its agonist activity at both the sigma-1 receptor and sigma-2 receptor. Diproqualone is used primarily for treating inflammatory pain associated with osteoarthritis and rheumatoid arthritis and more rarely, for treating insomnia, anxiety and neuralgia.

<span class="mw-page-title-main">Etaqualone</span> Chemical compound

Etaqualone is a quinazolinone-class GABAergic and is an analogue of methaqualone that was developed in the 1960s and marketed mainly in France and some other European countries. It has sedative, hypnotic, muscle relaxant and central nervous system depressant properties resulting from its agonist activity at the β-subtype of the GABAA receptor, and was used for the treatment of insomnia.

<span class="mw-page-title-main">Methylmethaqualone</span> Chemical compound

Methylmethaqualone (MMQ) is a quinazolinone and an analogue of methaqualone that has similar sedative and hypnotic properties to its parent compound and is around 3 times as potent in animal models. Methylmethaqualone differs from methaqualone by 4-methylation on the phenyl ring. It was made illegal in Germany in 1999 and listed by the DEA as a "drug of forensic interest" at about the same time, but little other information is available. It would appear that this compound was sold on the black market in Germany as a designer drug analogue of methaqualone.

<i>N</i>-Methylphenethylamine Chemical compound

N-Methylphenethylamine (NMPEA) is a naturally occurring trace amine neuromodulator in humans that is derived from the trace amine, phenethylamine (PEA). It has been detected in human urine and is produced by phenylethanolamine N-methyltransferase with phenethylamine as a substrate, which significantly increases PEA's effects. PEA breaks down into phenylacetaldehyde which is further broken down into phenylacetic acid by monoamine oxidase. When this is inhibited by monoamine oxidase inhibitors, it allows more of the PEA to be metabolized into nymphetamine (NMPEA) and not wasted on the weaker inactive metabolites.

<span class="mw-page-title-main">GABA receptor agonist</span>

A GABA receptor agonist is a drug that is an agonist for one or more of the GABA receptors, producing typically sedative effects, and may also cause other effects such as anxiolytic, anticonvulsant, and muscle relaxant effects. There are three receptors of the gamma-aminobutyric acid. The two receptors GABA-α and GABA-ρ are ion channels that are permeable to chloride ions which reduces neuronal excitability. The GABA-β receptor belongs to the class of G-Protein coupled receptors that inhibit adenylyl cyclase, therefore leading to decreased cyclic adenosine monophosphate (cAMP). GABA-α and GABA-ρ receptors produce sedative and hypnotic effects and have anti-convulsion properties. GABA-β receptors also produce sedative effects. Furthermore, they lead to changes in gene transcription.

Metabotropic glutamate receptor 2 (mGluR2) is a protein that, in humans, is encoded by the GRM2 gene. mGluR2 is a G protein-coupled receptor (GPCR) that couples with the Gi alpha subunit. The receptor functions as an autoreceptor for glutamate, that upon activation, inhibits the emptying of vesicular contents at the presynaptic terminal of glutamatergic neurons.

ABT-724 is a drug which acts as a dopamine agonist, and is selective for the D4 subtype. It was developed as a possible drug for the treatment of erectile dysfunction, although poor oral bioavailability means alternative drugs such as ABT-670 may be more likely to be developed commercially. Nonetheless, it continues to be used in scientific research into the function of the D4 receptor.

<span class="mw-page-title-main">Tiamenidine</span> Chemical compound

Tiamenidine (BAN, USAN, INN, also known as thiamenidine, Hoe 440) is an imidazoline compound that shares many of the pharmacological properties of clonidine. It is a centrally-acting α2 adrenergic receptor agonist (IC50 = 9.1 nM). It also acts as an α1-adrenergic receptor agonist to a far lesser extent (IC50 = 4.85 μM). In hypertensive volunteers, like clonidine, it significantly increased sinus node recovery time and lowered cardiac output. It was marketed (as tiamenidine hydrochloride) by Sanofi-Aventis under the brand name Sundralen for the management of essential hypertension.

<span class="mw-page-title-main">O-1269</span> Chemical compound

O-1269 is a drug that is a diarylpyrazole derivative, related to potent cannabinoid antagonist drugs such as rimonabant and surinabant. However O-1269 and several related drugs were unexpectedly found to act as full or partial agonists at the cannabinoid receptors rather than antagonists, and so produce the usual effects expected of cannabinoid agonists in animal tests, such as sedation and analgesic effects. The N-heptyl homolog O-1270 and the N-propyl homolog O-1399 also act as cannabinoid agonists with similar potency in vivo, despite weaker binding affinity at cannabinoid receptors compared to the pentyl homolog O-1269. Agonist-like and atypical cannabinoid activity has also been observed with a number of related compounds.

<i>N</i>-Methylserotonin Chemical compound

N-Methylserotonin is a tryptamine alkaloid. Chemically, it is a derivative of serotonin in which a methyl group resides at its alkyl amine. It is also called Nω-methylserotonin (Nω-methyl-5-hydroxytryptamine) to distinguish it from tryptamine-derived compounds in which a methyl group is bonded to the nitrogen atom of the indole group.
