Methamnetamine
Methamnetamine (also known as methylnaphetamine, MNA, MNT and PAL-1046) is a triple monoamine releasing agent and ''N''-methyl analog of the non-neurotoxic experimental drug naphthylaminopropane and the naphthalene analog of methamphetamine. It has been sold online as a designer drug. It acts as a releasing agent of serotonin, norepinephrine, and dopamine, with EC50 values of 13 nM, 34 nM, and 10 nM, respectively. Legal status Methamnetamine is illegal in Japan.

2-MAPB
2-MAPB is a recreational designer drug with empathogenic effects. As with other related substituted benzofuran derivatives such as 6-APB and 5-MAPB, 2-MAPB is a monoamine releaser with some selectivity for serotonin release, generally similar in pharmacological profile to MDMA but with greater activity as a directly acting agonist of 5-HT2 receptor subtypes and somewhat greater toxicity. 2-MAPB has been isolated from post-mortem toxicology screens in several drug-related fatal adverse reactions but generally only as a component of combinations of drugs, making it difficult to determine how much it contributed to the deaths. It is illegal in Japan.

Naphthylaminopropane
Naphthylaminopropane (PAL-287) is an experimental drug under investigation as of 2007 for the treatment of alcohol and stimulant addiction. Naphthylisopropylamine acts as a non-neurotoxic releasing agent of serotonin, norepinephrine, and dopamine, with EC50 values of 3.4 nM, 11.1 nM, and 12.6 nM, respectively. It also has affinity for the 5-HT2A, 5-HT2B, and 5-HT2C receptors (EC50 values = 466 nM, 40 nM, and 2.3 nM, respectively), and acts as a full agonist at 5-HT2B and as a partial agonist at 5-HT2C, while its affinity for 5-HT2A is probably too low to be significant. In animal studies, naphthylisopropylamine was shown to reduce cocaine self-administration, yet produced relatively weak stimulant effects when administered alone, being a (much) lesser stimulant than d-amphetamine for comparison. Further research is now being conducted in primates to see if it will be a useful substitute for treating drug addiction in humans as well. An important observation is that in behavi ...

Releasing Agent
A monoamine releasing agent (MRA), or simply monoamine releaser, is a drug that induces the synapse, release of a monoamine neurotransmitter from the synapse, presynaptic neuron into the synapse, leading to an increase in the extracellular concentrations of the neurotransmitter. Many drugs induce their effects in the body and/or brain via the release of monoamine neurotransmitters, e.g., trace amines, many substituted amphetamines, and related compounds. Types of MRAs MRAS can be classified by the monoamines they mainly release, although these drugs lie on a spectrum. * Selective for one neurotransmitter ** Serotonin releasing agent (SRA) ** Norepinephrine releasing agent (NRA) ** Dopamine releasing agent (DRA) * Non-selective, releasing two or more neurotransmitters ** Norepinephrine–dopamine releasing agent (NDRA) ** Serotonin–norepinephrine releasing agent (SNRA) ** Serotonin–dopamine releasing agent (SDRA) ** Serotonin–norepinephrine–dopamine releasing agent (SNDR ...

BMAPN
BMAPN (βk-methamnetamine) is a substituted cathinone derivative with stimulant effects. It inhibits dopamine reuptake and has rewarding and reinforcing properties in animal studies. It is banned under drug analogue legislation in a number of jurisdictions. The drug was at one point marketed under the name NRG-3, although only a minority of samples of substances sold under this name have been found to actually contain BMAPN, with most such samples containing mixtures of other cathinone derivatives. See also * βk-Ephenidine * Methamnetamine * Methylnaphthidate HDMP-28 or methylnaphthidate is a piperidine based stimulant drug, closely related to methylphenidate, but with the benzene ring replaced by naphthalene.

Serotonin Receptor Agonists
Serotonin () or 5-hydroxytryptamine (5-HT) is a monoamine neurotransmitter. Its biological function is complex and multifaceted, modulating mood, cognition, reward, learning, memory, and numerous physiological processes such as vomiting and vasoconstriction. Approximately 90% of the serotonin that the body produces is in the intestinal tract. Biochemically, the indoleamine molecule derives from the amino acid tryptophan, via the (rate-limiting) hydroxylation of the 5 position on the ring (forming the intermediate 5-hydroxytryptophan), and then decarboxylation to produce serotonin. Serotonin is primarily found in the enteric nervous system located in the gastrointestinal tract (GI tract). However, it is also produced in the central nervous system (CNS), specifically in the raphe nuclei located in the brainstem, Merkel cells located in the skin, pulmonary neuroendocrine cells and taste receptor cells in the tongue. Additionally, serotonin is stored in blood platelets and is rel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Designer Drugs
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 ...

Methamphetamines
Methamphetamine (contracted from ) is a potent central nervous system (CNS) stimulant that is mainly used as a recreational drug and less commonly as a second-line treatment for attention deficit hyperactivity disorder and obesity. Methamphetamine was discovered in 1893 and exists as two enantiomers: levo-methamphetamine and dextro-methamphetamine. ''Methamphetamine'' properly refers to a specific chemical substance, the racemic free base, which is an equal mixture of levomethamphetamine and dextromethamphetamine in their pure amine forms. It is rarely prescribed over concerns involving human neurotoxicity and potential for recreational use as an aphrodisiac and euphoriant, among other concerns, as well as the availability of safer substitute drugs with comparable treatment efficacy such as Adderall and Vyvanse. Dextromethamphetamine is a stronger CNS stimulant than levomethamphetamine. Both racemic methamphetamine and dextromethamphetamine are illicitly trafficked and sol ...

2β-Propanoyl-3β-(2-naphthyl)-tropane
2β-Propanoyl-3β-(2-naphthyl)-tropane or WF-23 (Wake Forest-23, named after the university where it was first created) is a cocaine analogue. It is several hundred times more potent than cocaine at being a serotonin-norepinephrine-dopamine reuptake inhibitor. As can be seen on PubMed, these acyl substituted phenyltropanes are highly potent MAT inhibitors and also have a very long half-life, spanning perhaps at least a few days; as the half-life of the dopamine transporter in rats was found to be 2-3 days under normal conditions (with agonists, antagonists, and transporter inhibitors altering the half-life), it may be that WF-23 largely or mostly binds to its transporters until they are degraded.

A cocaine analogue is an (usually) artificial construct of a novel chemical compound from (often the starting point of natural) cocaine's molecular structure, with the result product suf ...

Naphyrone
Naphyrone, also known as O-2482 and naphthylpyrovalerone, is a substituted cathinone drug derived from pyrovalerone that acts as a triple reuptake inhibitor, producing stimulant effects and has been reported as a novel designer drug. No safety or toxicity data is available on the drug. The drug has been marketed under the name NRG-1, although only a minority of samples of substances sold under this name have been found to actually contain naphyrone, and even samples that proved to contain genuine β-naphyrone were in some cases also found to contain the 1-naphthyl isomer α-naphyrone in varying proportions, further confusing the reported effects profile. Use in the United Kingdom Naphyrone emerged as a new legal high in the United Kingdom only months after the ban of similar drug mephedrone (which was also a cathinone derivative). Until July 2010 the substance was not controlled by the Misuse of Drugs Act 1971 and was therefore not illegal for someone to possess. The Medi ...
