2-Fluoromethcathinone
2-Fluoromethcathinone (2-FMC), also known as 2-flephedrone, is a psychostimulant and designer drug of the cathinone family. It acts as a dopamine and norepinephrine releasing agent (NDRA). Pharmacology The drug has an for dopamine release of 48.7nM and induces 85% release of norepinephrine at a concentration of 10μM. For comparison, the values of methcathinone are 49.9nM for dopamine release and 22.4nM for norepinephrine release and it induces 100% release of norepinephrine at a concentration of 10μM. Hence, compared to methcathinone, 2-FMC appears to be relatively more selective or efficacious for induction of dopamine release over norepinephrine release. It is notable in this regard that selective dopamine releasing agents are largely unknown.

Substituted Cathinone
Substituted cathinones, or simply cathinones, which include some stimulants and Empathogen-entactogen, entactogens, are chemical derivative, derivatives of cathinone. They feature a substituted phenethylamine, phenethylamine core with an alkyl functional group, group attached to the alpha and beta carbon, alpha carbon, and a ketone group attached to the alpha and beta carbon, beta carbon, along with additional Substitution reaction, substitutions. Cathinone occurs naturally in the plant khat whose leaves are chewed as a recreational drug. Substituted cathinones act as monoamine releasing agents and/or monoamine reuptake inhibitors, including of norepinephrine, dopamine, and/or serotonin. In contrast to substituted amphetamines, most substituted cathinones do not act as agonists of the human trace amine-associated receptor 1 (TAAR1). This may potentiate their stimulating and drug addiction, addictive effects. In addition, β-keto-substituted phenethylamines, such as βk-2C-B, app ...

3-Methoxymethcathinone
3-Methoxymethcathinone (3-MeOMC), also known as ''meta''-methoxymethcathinone (''m''-MeOMC), is a designer drug of the substituted cathinone family described as a stimulant. Similarly to other cathinones, it acts as a monoamine releasing agent, including of serotonin, dopamine, and norepinephrine. However, in contrast to cathinones and amphetamines, 3-MeOMC appears to show selectivity for induction of serotonin and dopamine release over release of norepinephrine, and hence may act as a partially selective serotonin–dopamine releasing agent (SDRA). Its values are 129nM for dopamine release and 306nM for serotonin release ''in vitro'', whereas it only induced 68% release of norepinephrine at a concentration of 10μM. For comparison, other related cathinones, including cathinone, methcathinone, 3-methylmethcathinone (3-MMC; metaphedrone), 4-methylmethcathinone (4-MMC; mephedrone), and 4-methoxymethcathinone (4-MeOMC; methedrone), induced 94 to 101% release of norepinephrine at 1 ...

2-Fluoromethamphetamine
2-Fluoromethamphetamine (2-FMA) is a stimulant drug of the amphetamine family which has been used as a designer drug. 2-FMA is commonly compared to lisdexamfetamine (Vyvanse), and dextroamphetamine due to its efficacy as a study or productivity aid. 2-FMA is purported to produce somewhat less euphoria than comparable amphetamines, likely due to its main mechanism of action consisting of norepinephrine reuptake inhibition. Chemistry 2-Fluoromethamphetamine is fluorinated analogue of methamphetamine, and is a regioisomer of 3-FMA and 4-FMA. It does not activate the serotonin receptors, including 5-HT2A, unlike most stimulant drugs of the amphetamine family. Legal status Canada As of 1996, 2-FMA is a controlled substance in Canada, due to being an analog of methamphetamine. China As of October 2015, 2-FMA is a controlled substance in China. Germany As of 13 December 2014, 2-FMA is a controlled substance in Germany. It is controlled under Anlage I BtMG (Narcotics Act, ...

Stimulant
Stimulants (also known as central nervous system stimulants, or psychostimulants, or colloquially as uppers) are a class of drugs that increase alertness. They are used for various purposes, such as enhancing attention, motivation, cognition, Mood disorder, mood, and physical activity, physical performance. Some stimulants occur naturally, while others are exclusively synthetic. Common stimulants include caffeine, nicotine, amphetamines, cocaine, methylphenidate, and modafinil. Stimulants may be subject to varying forms of regulation, or outright prohibition, depending on jurisdiction. Stimulants increase activity in the sympathetic nervous system, either directly or indirectly. Prototypical stimulants increase synaptic concentrations of neurotransmitter, excitatory neurotransmitters, particularly norepinephrine and dopamine (e.g., methylphenidate). Other stimulants work by binding to the Receptor (biochemistry), receptors of excitatory neurotransmitters (e.g., nicotine) or by ...

Methamphetamines
Methamphetamine (contracted from ) is a potent central nervous system (CNS) stimulant that is mainly used as a recreational or performance-enhancing drug and less commonly as a second-line treatment for attention deficit hyperactivity disorder (ADHD). It has also been researched as a potential treatment for traumatic brain injury. 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, but the hydrochloride salt, commonly called crystal meth, is widely used. Methamphetamine is rarely prescribed over concerns involving its 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 an ...

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, Australia, and New Zealand, as new psychoactive substances (NPS) as well as analogs of performance-enhancing drugs such as designer steroids. Some of these designer drugs 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 tr ...

Intrinsic Activity
Intrinsic activity (IA) and efficacy (Emax) refer to the relative ability of a drug- receptor complex to produce a maximum functional response. This must be distinguished from the affinity, which is a measure of the ability of the drug to bind to its molecular target, and the EC50, which is a measure of the potency of the drug and which is proportional to both efficacy and affinity. This use of the word "efficacy" was introduced by Stephenson (1956) to describe the way in which agonist An agonist is a chemical that activates a Receptor (biochemistry), receptor to produce a biological response. Receptors are Cell (biology), cellular proteins whose activation causes the cell to modify what it is currently doing. In contrast, an R ...s vary in the response they produce, even when they occupy the same number of receptors. High efficacy agonists can produce the maximal response of the receptor system while occupying a relatively low proportion of the receptors in that system. Th ...

Dopamine Releasing Agent
A dopamine releasing agent (DRA) is a type of drug which induces the release of dopamine in the Body (biology), body and/or brain. No binding selectivity, selective DRAs are currently known. However, non-selective DRAs, including norepinephrine–dopamine releasing agents (NDRAs) like amphetamine and methamphetamine, serotonin–norepinephrine–dopamine releasing agents (SNDRAs) like MDMA and mephedrone, and serotonin–dopamine releasing agents (SDRAs) like 5-chloro-αMT and BK-NM-AMT, are known. A closely related type of drug is a dopamine reuptake inhibitor (DRI). In contrast to the case of DRAs, many selective DRIs are known. Examples of selective DRIs include amineptine, modafinil, and vanoxerine. Selectivity No binding selectivity, selective and robust DRAs are currently known. The lack of known selective DRAs is related to the fact that it has proven extremely difficult to separate dopamine transporter (DAT) affinity (pharmacology), affinity from norepinephrine transpo ...
