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.

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.

Ethylphenidate
Ethylphenidate (EPH), also known as Baxtercaine in the United Kingdom is a psychostimulant and a close analog of methylphenidate. Ethylphenidate 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. However, considering the close similarities between ethylphenidate and methylphenidate and the fact that methylphenidate, like cocaine, actually does not primarily act as a "classical" reuptake inhibitor, but rather as an "inverse agonist at the DAT" (also called a "negative allosteric modulator at the DAT"), it is at least very likely that ethylphenidate also primarily acts as an inverse DAT agonist instead of (or at least only secondarily) as a classical reuptake inhibitor (which could be called a "competitive antagonist at ...

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.

HDEP-28
HDEP-28 or ethylnaphthidate is a piperidine based stimulant drug, closely related to ethylphenidate, but with the benzene ring replaced by naphthalene. It is even more closely related to HDMP-28, which acts as a potent serotonin–norepinephrine–dopamine reuptake inhibitor with several times the potency of methylphenidate and a short duration of action. Legality HDEP-28 was banned in the UK as a Temporary Class Drug from June 2015 following its unapproved sale as a designer drug, alongside 4-Methylmethylphenidate.

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.

Isopropylphenidate
Isopropylphenidate (also known as IPH and IPPD) is a piperidine based stimulant drug, closely related to methylphenidate, but with the methyl ester replaced by an isopropyl ester. It has similar effects to methylphenidate but with a longer duration of action, and was banned in the UK as a Temporary Class Drug from April 2015 following its unapproved sale as a designer drug. It has been researched as potential methylphenidate replacement for ADHD and narcolepsy, because of fewer side effects.

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 ...

Piperidine
Piperidine is an organic compound with the molecular formula (CH2)5NH. This heterocyclic compound, heterocyclic amine consists of a six-membered ring containing five methylene bridges (–CH2–) and one amine bridge (–NH–). It is a colorless liquid with an odor described as objectionable, and typical of amines. The name comes from the genus name ''Piper (genus), Piper'', which is the Latin word for Black pepper, pepper. Although piperidine is a common organic compound, it is best known as a representative structure element within many pharmaceuticals and alkaloids, such as natural-occurring Solenopsin, solenopsins. Production Piperidine was first reported in 1850 by the Scottish chemist Thomas Anderson (chemist), Thomas Anderson and again, independently, in 1852 by the French chemist Auguste André Thomas Cahours, Auguste Cahours, who named it. Both of them obtained piperidine by reacting piperine with nitric acid. Industrially, piperidine is produced by the hydrogenation o ...

Dexmethylphenidate
Dexmethylphenidate, sold under the brand name Focalin among others, is a strong central nervous system (CNS) stimulant medication used to treat attention deficit hyperactivity disorder (ADHD) in those over the age of five years. If no benefit is seen after four weeks it is reasonable to discontinue its use. It is taken by mouth. The immediate release formulation lasts up to five hours while the extended release formulation lasts up to twelve hours. Common side effects include abdominal pain, loss of appetite, and fever. Serious side effects may include abuse, psychosis, sudden cardiac death, mania, anaphylaxis, seizures, and dangerously prolonged erection. Safety during pregnancy and breastfeeding is unclear. Dexmethylphenidate is a central nervous system (CNS) stimulant. How it works in ADHD is unclear. It is the more active enantiomer of methylphenidate. Dexmethylphenidate was approved for medical use in the United States in 2001. It is available as a generic medication. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
