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.
Phenelzine, sold under the brand name Nardil among others, is a non-selective and irreversible monoamine oxidase inhibitor (MAOI) of the hydrazine family which is primarily used as an antidepressant and anxiolytic to treat depression and anxiety. Along with tranylcypromine and isocarboxazid, phenelzine is one of the few non-selective and irreversible MAOIs still in widespread clinical use.
Phenethylamine (PEA) is an organic compound, natural monoamine alkaloid, and trace amine, which acts as a central nervous system stimulant in humans. In the brain, phenethylamine regulates monoamine neurotransmission by binding to trace amine-associated receptor 1 (TAAR1) and inhibiting vesicular monoamine transporter 2 (VMAT2) in monoamine neurons. To a lesser extent, it also acts as a neurotransmitter in the human central nervous system. In mammals, phenethylamine is produced from the amino acid L-phenylalanine by the enzyme aromatic L-amino acid decarboxylase via enzymatic decarboxylation. In addition to its presence in mammals, phenethylamine is found in many other organisms and foods, such as chocolate, especially after microbial fermentation.
Thiophene is a heterocyclic compound with the formula C4H4S. Consisting of a planar five-membered ring, it is aromatic as indicated by its extensive substitution reactions. It is a colorless liquid with a benzene-like odor. In most of its reactions, it resembles benzene. Compounds analogous to thiophene include furan (C4H4O), selenophene (C4H4Se) and pyrrole (C4H4NH), which each vary by the heteroatom in the ring.
Phentermine, sold under the brand name Adipex-P among others, is a medication used together with diet and exercise to treat obesity. It is available by itself or as the combination phentermine/topiramate. Phentermine is taken by mouth.
Pargyline, sold under the brand name Eutonyl among others, is a monoamine oxidase inhibitor (MAOI) medication which has been used to treat hypertension but is no longer marketed. It has also been studied as an antidepressant, but was never licensed for use in the treatment of depression. The drug is taken by mouth.
Naphthylaminopropane, also known as naphthylisopropylamine (NIPA), is an experimental drug of the amphetamine and naphthylaminopropane families that was under investigation for the treatment of alcohol and stimulant addiction.
α,N-Dimethyltryptamine (α,N-DMT; developmental code names SK&F-7024, Ro 3-1715), also known as N-methyl-α-methyltryptamine (N-methyl-αMT), is a lesser-known substituted tryptamine and psychoactive drug. It is the α,N-dimethyl positional isomer of N,N-dimethyltryptamine (N,N-DMT).
1-Phenyl-2-propylaminopentane (PPAP), also known as α,N-dipropylphenethylamine (DPPEA) and by the developmental code name MK-306, is an experimental drug related to selegiline which acts as a catecholaminergic activity enhancer (CAE).
Pheniprazine, formerly sold under the brand names Catron and Cavodil, is an irreversible and non-selective monoamine oxidase inhibitor (MAOI) of the hydrazine group that was used as an antidepressant to treat depression in the 1960s. It was also used in the treatment of angina pectoris and schizophrenia. Pheniprazine has been largely discontinued due to toxicity concerns such as jaundice, amblyopia, and optic neuritis.
para-Chloroamphetamine (PCA), also known as 4-chloroamphetamine (4-CA), is a serotonin–norepinephrine–dopamine releasing agent (SNDRA) and serotonergic neurotoxin of the amphetamine family. It is used in scientific research in the study of the serotonin system, as a serotonin releasing agent (SRA) at lower doses to produce serotonergic effects, and as a serotonergic neurotoxin at higher doses to produce long-lasting depletions of serotonin.
MDAI, also known as 5,6-methylenedioxy-2-aminoindane, is an entactogen drug of the 2-aminoindane group which is related to MDMA and produces similar subjective effects.
3-Fluoroamphetamine is a stimulant drug from the amphetamine family which acts as a monoamine releaser with similar potency to methamphetamine but more selectivity for dopamine and norepinephrine release over serotonin. It is self-administered by mice to a similar extent to related drugs such as 4-fluoroamphetamine and 3-methylamphetamine.
Methiopropamine (MPA), also known as N-methylthiopropamine, is an organic compound structurally related to methamphetamine. Originally reported in 1942, the molecule consists of a thiophene group with an alkyl amine substituent at the 2-position. It appeared for public sale in the United Kingdom in December 2010 as a "research chemical" or "legal high", recently branded as Blow. It has limited popularity as a recreational stimulant.
Tetrindole was a drug candidate that functions by reversibly inhibiting monoamine oxidase A; it was first synthesized in Moscow in the early 1990s. Tetrindole is similar in its chemical structure to pirlindole (Pyrazidol), and metralindole.
G-130 is a drug with stimulant and anorectic effects, related to phenmetrazine.
3,4-Dichloroamphetamine (3,4-DCA), is an amphetamine derived drug invented by Eli Lilly in the 1960s, which has a number of pharmacological actions. It acts as a highly potent and selective serotonin releasing agent (SSRA) and binds to the serotonin transporter with high affinity, but also acts as a selective serotonergic neurotoxin in a similar manner to the related para-chloroamphetamine (PCA), though with slightly lower potency. It is also a monoamine oxidase inhibitor (MAOI), as well as a very potent inhibitor of the enzyme phenylethanolamine N-methyl transferase which normally functions to transform noradrenaline into adrenaline in the body.
α-Pyrrolidinopentiothiophenone is a synthetic stimulant of the cathinone and thiopropamine (thiophenylpropylamine) families that has been sold online as a designer drug. It is an analogue of α-PVP where the phenyl ring has been replaced by thiophene.
The pharmacology of selegiline pertains to the pharmacodynamic and pharmacokinetic properties of the antiparkinsonian and antidepressant selegiline (L-deprenyl). Selegiline is available in a few different forms, including oral tablets and capsules, orally disintegrating tablets (ODTs), and transdermal patches. These forms have differing pharmacological properties.
α-Propylphenethylamine, also known as 1-phenyl-2-aminopentane, is a stimulant drug of the phenethylamine and amphetamine families. It is the analogue of the β-phenethylamine (PEA) derivatives amphetamine and phenylisobutylamine in which the α-alkyl chain has been further lengthened to be a propyl group.
