4-Methylmethylphenidate
''threo''-4-Methylmethylphenidate (4-MeTMP) is a stimulant drug related to methylphenidate. It is slightly less potent than methylphenidate and has relatively low efficacy at blocking dopamine reuptake despite its high binding affinity, which led to its investigation as a possible substitute drug for treatment of stimulant abuse (cf. nocaine). On the other hand, several other simple ring-substituted derivatives of ''threo''-methylphenidate such as the 4-fluoro and 3-chloro compounds are more potent than methylphenidate both in efficacy as dopamine reuptake inhibitors and in animal drug discrimination assays. Legality 4-Methylmethylphenidate was banned in the UK as a Temporary Class Drug from June 2015 following its unapproved sale as a designer drug.

Methylphenidate Derivatives
This is a list of methylphenidate (MPH or MPD) analogues, or Phenidates. The most well known compound from this family, methylphenidate, is widely prescribed around the world for the treatment of attention deficit hyperactivity disorder (ADHD) and certain other indications. Several other derivatives including rimiterol, phacetoperane and pipradrol also have more limited medical application. A rather larger number of these compounds have been sold in recent years as designer drugs, either as quasi-legal substitutes for illicit stimulants such as methamphetamine or cocaine, or as purported "study drugs" or nootropics. More structurally diverse compounds such as Desoxypipradrol (and thus Pipradrol, including such derivatives as AL-1095, Diphemethoxidine, SCH-5472 and D2PM), and even mefloquine, 2-benzylpiperidine, rimiterol, enpiroline and DMBMPP, can also be considered structurally related, with the former ones also functionally so, as loosely analogous compounds.

3,4-Dichloromethylphenidate
3,4-Dichloromethylphenidate (also known as 3,4-CTMP or 3,4-DCMP) is a stimulant drug related to methylphenidate. Dichloromethylphenidate is a potent psychostimulant that acts as both a dopamine reuptake inhibitor and norepinephrine reuptake inhibitor, meaning it effectively boosts the levels of the norepinephrine and dopamine neurotransmitters in the brain, by binding to, and partially blocking the transporter proteins that normally remove those monoamines from the synaptic cleft. 3,4-DCMP, the ''threo''-diastereomer, is approximately seven times more potent than methylphenidate in animal studies, but has weaker reinforcing effects due to its slower onset of action. However, H. M. Deutsch's discrimination ratio implies it to be more reinforcing than cocaine. Legality As of October 2015 3,4-CTMP is a controlled substance in China. 3,4-CTMP was banned in the UK as a Temporary Class Drug from April 2015 following its unapproved sale as a designer drug.

4-Methylphenmetrazine
4-Methylphenmetrazine (mephenmetrazine, 4-MPM, PAL-747) 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 was first identified in Slovenia in 2015, and has been shown to act as a monoamine releaser with some preference for serotonin release.

Propylphenidate
Propylphenidate (also known as PPH) is a piperidine based stimulant drug, closely related to methylphenidate, but with the methyl ester replaced by a propyl ester. It was banned in the UK as a Temporary Class Drug from April 2015 following its unapproved sale as a designer drug. Legal status Propylphenidate is illegal in Sweden as of 26. January 2016, and in Finland since 2017.

Temporary Class Drug
A temporary class drug is a relatively new status for controlled drugs, which has been adopted in some jurisdictions, notably New Zealand and the United Kingdom, to attempt to bring newly synthesised designer drugs under legal control. The controlled drug legislation in these jurisdictions requires drug scheduling decisions to follow an evidence-based process, where the harms of the drug are assessed and reviewed so that an appropriate legal status can be assigned. Since many designer drugs sold in recent years have had little or no published research that could help inform such a decision, they have been widely sold as "legal highs", often for months, before sufficient evidence accumulates to justify placing them on the controlled drug schedules. This situation has been deemed to be undesirable, as every time a designer drug has been banned, novel compounds with similar effects have been quickly developed and brought to market, often with worse health consequences reported than the ...

HDMP-28
HDMP-28 or methylnaphthidate is a piperidine based stimulant drug, closely related to methylphenidate, but with the benzene ring replaced by naphthalene. It is a potent dopamine reuptake inhibitor, with several times the potency of methylphenidate and a short duration of action, and is a structural isomer of another potent dopamine reuptake inhibitor, N,O-Dimethyl-4-(2-naphthyl)piperidine-3-carboxylate. Most of the TMP analogs of HDMP-28 have SERT Ki values in the range >10,000 and so are selective for dopamine and noradrenaline reuptake, with little or no effect on serotonin. HDMP-28 has high affinity to SERT, and so behaves as a triple reuptake inhibitor. D.R. = Discrimination Ratio = HA ÷ HFT. A low D.R. = addictive, whereas a high D.R. = low propensity for self-administration. Legality HDMP-28 is illegal in Switzerland as of December 2015.

3-Bromomethylphenidate
3-Bromomethylphenidate (3-Br-MPH) is a compound from the phenidate family, which has reportedly been sold as a designer drug. It showed the most potent binding to the dopamine transporter of a series of ring-substituted methylphenidate derivatives, and produced stimulant effects in animal studies.

4-Fluoromethylphenidate
4-Fluoromethylphenidate (also known as 4-FMPH and 4F-MPH) is a stimulant drug that acts as a higher potency dopamine reuptake inhibitor than the closely related methylphenidate. 4-Fluoromethylphenidate was studied further along with other analogues of (±)-threo-methylphenidate (TMP) to assess their potential as anti-cocaine medications. 4F-MPH was reported as having an ED50 mg/kg of 0.26 (0.18–0.36), regarding its efficacy as a substitute for cocaine, and a relative potency of 3.33 compared to methylphenidate for the same purpose. This is based on its binding strength to the dopamine transporter vs. its activity as a dopamine reuptake inhibitor. In theory, this would block some of the effects of cocaine, without being as addictive. This has been misinterpreted as a dopamine vs. norepinephrine selectivity ratio. Another study found that in the threo-isomers of methylphenidate, the meta- and para-substituted compounds with electron-withdrawing substituents tended to have incre ...

Methyl Esters
In organic chemistry, a methyl group is an alkyl derived from methane, containing one carbon atom bonded to three hydrogen atoms, having chemical formula . In formulas, the group is often abbreviated as Me. This hydrocarbon group occurs in many organic compounds. It is a very stable group in most molecules. While the methyl group is usually part of a larger molecule, bounded to the rest of the molecule by a single covalent bond (), it can be found on its own in any of three forms: methanide anion (), methylium cation () or methyl radical (). The anion has eight valence electrons, the radical seven and the cation six. All three forms are highly reactive and rarely observed. Methyl cation, anion, and radical Methyl cation The methylium cation () exists in the gas phase, but is otherwise not encountered. Some compounds are considered to be sources of the cation, and this simplification is used pervasively in organic chemistry. For example, protonation of methanol gives an electr ...

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 ...

Stimulants
Stimulants (also often referred to as psychostimulants or colloquially as uppers) is an overarching term that covers many drugs including those that increase activity of the central nervous system and the body, drugs that are pleasurable and invigorating, or drugs that have Sympathomimetic drug, sympathomimetic effects. Stimulants are widely used throughout the world as prescription medicines as well as without a prescription (either legally or Prohibition (drugs), illicitly) as performance-enhancing substance, performance-enhancing or recreational drug use, recreational drugs. Among narcotics, stimulants produce a noticeable crash or ''Comedown (drugs), comedown'' at the end of their effects. The most frequently prescribed stimulants as of 2013 were lisdexamfetamine (Vyvanse), methylphenidate (Ritalin), and amphetamine (Adderall). It was estimated in 2015 that the percentage of the world population that had used cocaine during a year was 0.4%. For the category "amphetamines and p ...
