Ketamine is a dissociative anesthetic used medically for induction and maintenance of anesthesia. It is also used as a treatment for depression and in pain management. Ketamine is an NMDA receptor antagonist which accounts for most of its psychoactive effects.
Lipoic acid (LA), also known as α-lipoic acid, alpha-lipoic acid (ALA) and thioctic acid, is an organosulfur compound derived from caprylic acid (octanoic acid). ALA, which is made in animals normally, is essential for aerobic metabolism. It is also available as a dietary supplement or pharmaceutical drug in some countries. Lipoate is the conjugate base of lipoic acid, and the most prevalent form of LA under physiological conditions. Only the (R)-(+)-enantiomer (RLA) exists in nature. RLA is an essential cofactor of many processes.
Aniracetam, also known as N-anisoyl-2-pyrrolidinone, is a racetam which is sold in Europe as a prescription drug. It is not approved by the Food and Drug Administration for use in the United States as a prescription medication or dietary supplement. Despite the FDA's lack of approval, the drug is readily available over-the-counter in misbranded dietary supplements.
α-Pyrrolidinopropiophenone (α-PPP), is a stimulant drug. It is similar in structure to the appetite suppressant diethylpropion and has analogous effects in animals. Little is known about this compound, but it has been detected by laboratories in Germany as an ingredient in "ecstasy" tablets seized by law enforcement authorities. This drug has been found to produce stimulant effects in animals and produces highly stimulating effects in humans, based on the experiences of the individuals who have tried it. Most of the individuals who have tried it prefer α-PVP to it, but prefer this drug over α-PVT. It is said to lack euphoria compared to α-PVP.
4'-Methoxy-α-pyrrolidinopropiophenone (MOPPP) is a stimulant designer drug of the pyrrolidinophenone class. It has the potential to produce euphoria, an effect shared with other classical stimulants.
An enantiopure drug is a pharmaceutical that is available in one specific enantiomeric form. Most biological molecules are present in only one of many chiral forms, so different enantiomers of a chiral drug molecule bind differently to target receptors. Chirality can be observed when the geometric properties of an object is not superimposable with its mirror image. Two forms of a molecule are formed from a chiral carbon, these two forms are called enantiomers. One enantiomer of a drug may have a desired beneficial effect while the other may cause serious and undesired side effects, or sometimes even beneficial but entirely different effects. The desired enantiomer is known as an eutomer while the undesired enantiomer is known as the distomer. When equal amounts of both enantiomers are found in a mixture, the mixture is known as a racemic mixture. If a mixture for a drug does not have a 1:1 ratio of its enantiomers it is a candidate for an enantiopure drug. Advances in industrial chemical processes have made it economical for pharmaceutical manufacturers to take drugs that were originally marketed as a racemic mixture and market the individual enantiomers, either by specifically manufacturing the desired enantiomer or by resolving a racemic mixture. On a case-by-case basis, the U.S. Food and Drug Administration (FDA) has allowed single enantiomers of certain drugs to be marketed under a different name than the racemic mixture. Also case-by-case, the United States Patent Office has granted patents for single enantiomers of certain drugs. The regulatory review for marketing approval and for patenting is independent, and differs country by country.
Arylcyclohexylamines, also known as arylcyclohexamines or arylcyclohexanamines, are a chemical class of pharmaceutical, designer, and experimental drugs.
PCPr is an arylcyclohexylamine dissociative anesthetic drug with hallucinogenic and stimulant effects. It is around the same potency as phencyclidine, although slightly less potent than the ethyl homologue eticyclidine, and has reportedly been sold as a designer drug in Germany and other European countries since the late 1990s.
Methoxetamine, abbreviated as MXE, is a dissociative hallucinogen that has been sold as a designer drug. It differs from many dissociatives such as ketamine and phencyclidine (PCP) that were developed as pharmaceutical drugs for use as general anesthetics in that it was designed specifically to increase the antidepressant effects of ketamine.
N-Desalkylflurazepam is a benzodiazepine analog and an active metabolite of several other benzodiazepine drugs including flurazepam, flutoprazepam, fludiazepam, midazolam, flutazolam, quazepam, and ethyl loflazepate. It is long-acting, prone to accumulation, and binds unselectively to the various benzodiazepine receptor subtypes. It has been sold as a designer drug from 2016 onward.
Methoxyketamine or 2-MeO-2-deschloroketamine is a designer drug of the arylcyclohexylamine class first reported in 1963. It is an analog of ketamine in which the chlorine atom has been replaced with a methoxy group. Its synthesis by rearrangement of an amino ketone has been reported. As an arylcyclohexylamine, methoxyketamine most likely functions as an NMDA receptor antagonist. It produces sedative, hallucinogenic, and anesthetic effects, but with a lower potency than ketamine itself.
Hydroxybupropion, or 6-hydroxybupropion, is the major active metabolite of the antidepressant and smoking cessation drug bupropion. It is formed from bupropion by the liver enzyme CYP2B6 during first-pass metabolism. With oral bupropion treatment, hydroxybupropion is present in plasma at area under the curve concentrations that are as many as 16 to 20 times greater than those of bupropion itself, demonstrating extensive conversion of bupropion into hydroxybupropion in humans. As such, hydroxybupropion is likely to play a very important role in the effects of oral bupropion, which could accurately be thought of as functioning largely as a prodrug to hydroxybupropion.
Norketamine, or N-desmethylketamine, is the major active metabolite of ketamine, which is formed mainly by CYP3A4. Similarly to ketamine, norketamine acts as a noncompetitive NMDA receptor antagonist, but is about 3–5 times less potent as an anesthetic in comparison.
3-Hydroxyphencyclidine (3-HO-PCP) is a dissociative of the arylcyclohexylamine class related to phencyclidine (PCP) that has been sold online as a designer drug.
2-Fluorodeschloroketamine is a dissociative anesthetic related to ketamine. Its sale and use as a designer drug has been reported in various countries. It is an analogue of ketamine where the chlorine group has been replaced by fluorine. Due to its recent emergence, the pharmacological specifics of the compound are mostly unclear, but effects are reported to be similar to its parent compound, ketamine.
2-Oxo-PCE is a dissociative anesthetic of the arylcyclohexylamine class that is closely related to deschloroketamine and eticyclidine, and has been sold online as a designer drug.
N-t-BOC-MDMA is a chemical compound which can be both a synthetic precursor to, or a prodrug of the empathogenic drug MDMA. It was first identified in Australia in 2015 as a seizure by customs, and has subsequently been found in China, the Netherlands and other European countries. Originally it was thought to be intended as a non-illegal form of MDMA which could be easily converted into the prohibited final product after importation, however one seizure by police found N-t-BOC-MDMA in the process of being pressed into pills, and experiments with simulated gastric fluid confirmed that it can be broken down to MDMA by human stomach acid. Similar N-protected compounds such as N-t-BOC-methamphetamine, N-p-tosyl-methamphetamine, N-t-BOC-ketamine, N-t-BOC-norketamine, and N-methoxycarbonyl-MDA have also been encountered by law enforcement.
Chiral inversion is the process of conversion of one enantiomer of a chiral molecule to its mirror-image version with no other change in the molecule.
Fluorexetamine is a recreational designer drug from the arylcyclohexylamine family, with dissociative effects. It has reportedly been sold over the internet since around 2017, though has remained relatively uncommon.
2F-NENDCK is a recreational designer drug from the arylcyclohexylamine family, with dissociative effects.
