α-Methyltryptamine is a psychedelic, stimulant, and entactogen drug of the tryptamine family. It was originally developed as an antidepressant at Upjohn in the 1960s, and was used briefly as an antidepressant in the Soviet Union under the brand name Indopan or Indopane before being discontinued.
Phenmetrazine, sold under the brand name Preludin among others, is a stimulant drug first synthesized in 1952 and originally used as an appetite suppressant, but withdrawn from the market in the 1980s due to widespread misuse. It was initially replaced by its analogue phendimetrazine which functions as a prodrug to phenmetrazine, but now it is rarely prescribed, due to concerns of misuse and addiction. Chemically, phenmetrazine is a substituted amphetamine containing a morpholine ring or a substituted phenylmorpholine.
Methedrone is a recreational drug of the cathinone chemical class. Chemically, methedrone is closely related to para-methoxymethamphetamine (PMMA), methylone and mephedrone. Methedrone received media attention in 2009 after the death of two young Swedish men. In both cases toxicology analysis showed methedrone was the only drug present in both men during the time of their overdose and subsequent deaths.
4-Benzylpiperidine is a drug and research chemical used in scientific studies. It has been encountered as a designer drug.
α-Pyrrolidinopentiophenone (α-PVP), also known as α-pyrrolidinovalerophenone, O-2387, β-keto-prolintane, prolintanone, or desmethylpyrovalerone, is a synthetic stimulant of the cathinone class developed in the 1960s that has been sold as a designer drug and often consumed for recreational reasons. α-PVP is chemically related to pyrovalerone and is the ketone analog of prolintane.
Substituted cathinones, or simply cathinones, which include some stimulants and entactogens, are derivatives of cathinone. They feature a phenethylamine core with an alkyl group attached to the alpha carbon, and a ketone group attached to the beta carbon, along with additional substitutions. Cathinone occurs naturally in the plant khat whose leaves are chewed as a recreational drug.
G-130 is a drug with stimulant and anorectic effects, related to phenmetrazine.
4,4'-Dimethylaminorex, sometimes referred to by the street name "Serotoni", is a psychostimulant and entactogen designer drug related to aminorex, 4-methylaminorex, and pemoline. It was first detected in the Netherlands in December 2012, and has been sold as a designer drug around Europe since mid-2013.
3-Fluorophenmetrazine is a phenylmorpholine-based stimulant and fluorinated analogue of phenmetrazine that has been sold online as a designer drug.
α-Pyrrolidinohexiophenone is a synthetic stimulant drug of the cathinone class developed in the 1960s which has been reported as a novel designer drug.
Substituted phenylmorpholines, or substituted phenmetrazines alternatively, are chemical derivatives of 2-phenylmorpholine or of the psychostimulant drug phenmetrazine. Most such compounds act as releasers of monoamine neurotransmitters, and have stimulant effects. Some also act as agonists at serotonin receptors, and compounds with an N-propyl substitution act as dopamine receptor agonists. A number of derivatives from this class have been investigated for medical applications, such as for use as anorectics or medications for the treatment of ADHD. Some compounds have also become subject to illicit use as designer drugs.
Mexedrone is a stimulant and an entactogen drug of the cathinone class that has been sold online as a designer drug. It is the alpha-methoxy derivative of Mephedrone.
N-Ethylhexedrone (also known as α-ethylaminocaprophenone, N-ethylnorhexedrone, hexen, and NEH) is a stimulant of the cathinone class that acts as a norepinephrine–dopamine reuptake inhibitor (NDRI) with IC50 values of 0.0978 and 0.0467 μM, respectively. N-Ethylhexedrone was first mentioned in a series of patents by Boehringer Ingelheim in the 1960s which led to the development of the better-known drug methylenedioxypyrovalerone (MDPV). Since the mid-2010s, N-ethylhexedrone has been sold online as a designer drug. In 2018, N-ethylhexedrone was the second most common drug of the cathinone class to be identified in Drug Enforcement Administration seizures.
5-MBPB is an amphetamine and phenylisobutylamine derivative which is structurally related to MDMA and has been sold as a designer drug. It can be described as the benzofuran-5-yl analogue of MBDB or the butanamine homologue of 5-MAPB, and is also a structural isomer of 5-EAPB and 6-EAPB. Anecdotal reports suggest this compound has been sold as a designer drug in various European countries since early 2015, but the first definitive identification was made in December 2015 by a forensic laboratory in Slovenia.
2-Phenyl-3,5-dimethylmorpholine is a drug with stimulant and anorectic effects, related to phenmetrazine. Based on what is known from other phenylmorpholines with similar structure, it likely acts as a norepinephrine-dopamine releasing agent and may produce effects similar or slightly different to phenmetrazine.
α-Pyrrolidinoisohexanophenone is a stimulant drug of the cathinone class that has been sold online as a designer drug. It acts as a potent norepinephrine-dopamine reuptake inhibitor (NDRI). In July 2016 α-PHiP was first identified as a designer drug when it was reported to the EMCDDA by a forensic laboratory in Slovenia. It is a positional isomer of pyrovalerone, with the methyl group shifted from the 4-position of the aromatic ring to the 4-position of the acyl chain. Similarly to other cathinones, use of α-PiHP can result in compulsive redosing, addiction, anxiety, paranoia, and psychosis.
TH-PVP is a substituted cathinone derivative which has been sold as a designer drug. It was first identified by a forensic laboratory in Hungary in 2015, but has subsequently been found in numerous other countries around the world including Spain, Belgium, Poland, Turkey and Brazil.
3-Chlorophenmetrazine is a recreational designer drug with stimulant effects. It is a substituted phenylmorpholine derivative, closely related to better known drugs such as phenmetrazine and 3-fluorophenmetrazine. It has been shown to act as a monoamine releaser with some preference for dopamine and noradrenaline release over serotonin.
2-Phenylmorpholine is the parent compound of the substituted phenylmorpholine class of compounds. Examples of 2-phenylmorpholine derivatives include phenmetrazine (3-methyl-2-phenylmorpholine), phendimetrazine ( -3,4-dimethyl-2-phenylmorpholine), and pseudophenmetrazine ( -3-methyl-2-phenylmorpholine), which are monoamine releasing agents (MRAs) and psychostimulants. 2-Phenylmorpholine itself is a potent norepinephrine–dopamine releasing agent (NDRA) and hence may act as a stimulant similarly.
