2-Piperidinyl compounds

Methylphenidate, sold under the brand name Ritalin and Concerta, among others, is a central nervous system (CNS) stimulant used in the treatment of attention deficit hyperactivity disorder (ADHD) and narcolepsy. It may be taken by mouth or applied to the skin, and different formulations have varying durations of effect. For ADHD, the effectiveness of methylphenidate is comparable to atomoxetine but modestly lower than amphetamine. However, methylphenidate is preferred as a first-line treatment in children, while amphetamine is preferred in adults. Methylphenidate reduces core ADHD symptoms and

Coniine is a poisonous chemical compound, an alkaloid present in and isolable from poison hemlock (Conium maculatum), where its presence has been a source of significant economic, medical, and historico-cultural interest; coniine is also produced by the yellow pitcher plant (Sarracenia flava), and fool's parsley (Aethusa cynapium). Its ingestion and extended exposure are toxic to humans and all classes of livestock; its mechanism of poisoning involves disruption of the central nervous system, with death caused by respiratory paralysis. The biosynthesis of coniine contains as its penultimate st

Anabasine is a pyridine and piperidine alkaloid found in the tree tobacco (Nicotiana glauca) plant, as well as in tree tobacco's close relative the common tobacco plant (Nicotiana tabacum). It is a structural isomer of, and chemically similar to, nicotine. It has been used as an insecticide.

Dexmethylphenidate, sold under the brand name Focalin among others, is a central nervous system (CNS) stimulant used in the treatment of attention deficit hyperactivity disorder (ADHD) in those over the age of five years. It is taken by mouth. The immediate-release formulation lasts up to five hours while the extended-release formulation lasts up to twelve hours. It is the more active enantiomer of methylphenidate. Methylphenidate has been shown to be more effective than atomoxetine and superior in treating ADHD symptoms when compared.

Pipradrol, also known by its brand name Meratran, is a mild central nervous system stimulant that acts as a norepinephrine-dopamine reuptake inhibitor. Developed in the United States in the 1940s and patented in 1953, pipradrol was initially marketed as an antidepressant in the mid-1950s. It was subsequently used as an adjunct treatment for various conditions, including obesity, senile dementia, narcolepsy, and schizophrenia.

Conhydrine is a poisonous alkaloid found in poison hemlock (Conium maculatum) in small quantities.

Ethylphenidate (EPH) is a central nervous system (CNS) stimulant and a close analog of methylphenidate.

Desoxypipradrol, also known as 2-⁠diphenylmethylpiperidine (2-DPMP), is a drug developed by Ciba in the 1950s which acts as a norepinephrine-dopamine reuptake inhibitor (NDRI).

Rimiterol (INN/USAN) is a third-generation short-acting β2 agonist.

3,4-dichloromethylphenidate (abbreviated as 3,4-DCMP, and incorrectly as 3,4-CTMP for the d,l-threo diastereomer) is a potent stimulant drug from the phenidate class closely related to methylphenidate. It acts as a potent serotonin-norepinephrine-dopamine reuptake inhibitor with a long duration of action. It has been sold online as a designer drug.

2-Benzylpiperidine is a stimulant drug of the arylpiperidine family. It is similar in structure to certain other stimulants such as methylphenidate and desoxypipradrol. However, it is far less potent as a monoamine reuptake inhibitor in comparison. The drug is little used as a stimulant, with its main use being as a synthetic intermediate in the manufacture of other drugs.

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.
