Cocaine Reverse Ester
Cocaine reverse ester, (also known as Reverse ester cocaine or REC) is a tropane derivative drug which is a reverse ester of cocaine, with the 2-COOCH3 methoxycarbonyl group swapped to an isomeric OCOCH3 acetoxy group. It was synthesised because of the observation that the reverse ester pairs of several structurally related substances show similar activity to each other (see e.g. methylphenidate vs phacetoperane, pethidine vs desmethylprodine). Cocaine reverse ester however did not produce cocaine-like stimulant effects in animal studies, and is also illegal in many jurisdictions as a structural isomer of cocaine; nevertheless it has attracted attention from vendors of quasi-legal designer drugs as a potential alternative to cocaine.

Tropane
Tropane is a nitrogenous Bicyclic molecule, bicyclic organic compound. It is mainly known for the other alkaloids derived from it, which include atropine and cocaine, among others. Tropane alkaloids occur in plants of the families Erythroxylaceae (including coca) and Solanaceae (including Mandragora officinarum, mandrake, henbane, deadly nightshade, datura, potato, tomato). Structurally, tropane is cycloheptane with a nitrogen bridge between carbons 1 and 5 and an additional methyl group attached to the nitrogen. While carbons 1 and 5 are asymmetric carbons, tropane itself is optically inactive due to mirror symmetry. 8-Azabicyclo[3.2.1]octane (tropane without the ''N''-methyl group) is known as nortropane or nor-tropane.

Ester
In chemistry, an ester is a compound derived from an oxoacid (organic or inorganic) in which at least one hydroxyl group () is replaced by an alkoxy group (), as in the substitution reaction of a carboxylic acid and an alcohol. Glycerides are fatty acid esters of glycerol; they are important in biology, being one of the main classes of lipids and comprising the bulk of animal fats and vegetable oils. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. They perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Phosphoesters form the backbone of DNA molecules. Nitrate esters, such as nitroglycerin, are known for their explosive properties. '' Nomenclature Etymology Th ...

Cocaine
Cocaine (from , from , ultimately from Quechuan languages, Quechua: ''kúka'') is a central nervous system (CNS) stimulant mainly recreational drug use, used recreationally for its euphoria, euphoric effects. It is primarily obtained from the leaves of two Coca species native to South America, ''Erythroxylum coca'' and ''Erythroxylum novogranatense''. After extraction from coca leaves and further processing into cocaine hydrochloride (powdered cocaine), the drug is often Insufflation (medicine), snorted, applied topical administration, topically to the mouth, or dissolved and injection (medicine), injected into a vein. It can also then be turned into free base form (crack cocaine), in which it can be heated until sublimated and then the vapours can be smoking, inhaled. Cocaine stimulates the mesolimbic pathway, reward pathway in the brain. Mental effects may include an euphoria, intense feeling of happiness, sexual arousal, psychosis, loss of contact with reality, or psychomo ...

Methylphenidate
Methylphenidate, sold under the brand names Ritalin and Concerta among others, is the most widely prescribed central nervous system (CNS) stimulant medication used to treat attention deficit hyperactivity disorder (ADHD) and, to a lesser extent, narcolepsy. It is a primary medication for ADHD; it may be taken by mouth or applied to the skin, and different formulations have varying durations of effect, commonly ranging from 2–4 hours. Though there is little to no evidence, and in some cases contradictory evidence, to support its use as an athletic performance enhancer, cognitive enhancer, aphrodisiac or euphoriant, claims persist that it can be used for these purposes. Common adverse reactions of methylphenidate include: tachycardia, palpitations, headache, insomnia, anxiety, hyperhidrosis, weight loss, decreased appetite, dry mouth, nausea, and abdominal pain. Withdrawal symptoms may include: chills, depression, drowsiness, dysphoria, exhaustion, headaches, irritabili ...

Pethidine
Pethidine, also known as meperidine and sold under the brand name Demerol among others, is a synthetic opioid analgesic, pain medication of the phenylpiperidine class. Synthesized in 1938 as a potential anticholinergic agent by the German chemist Otto Eisleb, its analgesic properties were first recognized by Otto Schaumann while working for IG Farben, Germany. Pethidine is the prototype of a large family of analgesics including the pethidine 4-phenylpiperidines (piminodine, anileridine and others), the prodines (alphaprodine, MPPP, ''etc.''), bemidones (ketobemidone, etc.) and others more distant, including diphenoxylate and analogues. Pethidine is indicated for the treatment of moderate to severe pain, and is delivered as a hydrochloride salt in tablets, as a syrup, or by intramuscular, Subcutaneous injection, subcutaneous, or intravenous injection. For much of the 20th century, pethidine was the opioid of choice for many physicians; in 1975, 60% of doctors prescribed it for acu ...

Desmethylprodine
Desmethylprodine or 1-methyl-4-phenyl-4-propionoxypiperidine (MPPP, Ro 2-0718) is an opioid analgesic drug developed in the 1940s by researchers at Hoffmann-La Roche. Desmethylprodine has been labeled by the Drug Enforcement Administration, DEA as a Controlled Substances Act#Schedule_I_controlled_substances, Schedule I drug in the United States. It is an Analog (chemistry), analog of pethidine (meperidine) a Controlled Substances Act#Schedule_II_controlled_substances, Schedule II drug. Chemically, it is a reversed ester of pethidine which has about 70% of the potency of morphine. Unlike its derivative prodine, it was not reported to exhibit optical isomerism. It was reported to have 30 times the activity of pethidine and a greater analgesic effect than morphine in rats, and it was demonstrated to cause central nervous system stimulation in mice. History Desmethylprodine was first synthesized in 1947 at Hoffman-LaRoche Laboratories by Albert Ziering and John Lee. They found th ...

Stimulant
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 ...

Structural Isomer
In chemistry, a structural isomer (or constitutional isomer in the IUPAC nomenclature) of a chemical compound, compound is another compound whose molecule has the same number of atoms of each element, but with logically distinct chemical bond, bonds between them. The term metamer was formerly used for the same concept. For example, butanol , methyl propyl ether , and diethyl ether have the same molecular formula but are three distinct structural isomers. The concept applies also to polyatomic ions with the same total charge. A classical example is the cyanate ion and the fulminate ion . It is also extended to ionic compounds, so that (for example) ammonium cyanate and urea are considered structural isomers,William F. Bynum, E. Janet Browne, Roy Porter (2014): ''Dictionary of the History of Science''. 530 pages. and so are methylammonium formate and ammonium acetate . Structural isomerism is the most radical type of isomerism. It is opposed to stereoisomerism, in which ...

Designer Drug
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 ...

3-(p-Fluorobenzoyloxy)tropane
3β-(''p''-Fluorobenzoyloxy)tropane, (8-Methyl-8-azabicyclo .2.1ct-3-yl 4-fluorobenzoic acid ester, 4-fluorotropacocaine, 3-Pseudotropyl-4-fluorobenzoate, 3-pseudotropyl-4-fluorobenzoate, pFBT) is a tropane derivative drug which acts as a local anaesthetic, having around 30% the stimulant potency of cocaine but around the same potency as a local anaesthetic. It has been investigated as a potential radiolabelled agent for studying receptor binding, but was not adopted for this application. The main application for fluorotropacocaine, however, has been as a designer drug analogue of cocaine, first detected by the EMCDDA in 2008, and subsequently sold as an ingredient of various "bath salt" powder products, usually mixed in combination with other stimulant drugs such as caffeine, dimethocaine, desoxypipradrol or substituted cathinone derivatives.

4′-Fluorococaine
4′-Fluorococaine is a tropane derivative drug which is a synthetic analogue of cocaine. Unlike related compounds such as the corresponding 4′-fluorophenyltropane derivative CFT and the 2′-hydroxy analogue salicylmethylecgonine, 4′-fluorococaine has only around the same potency as cocaine as an inhibitor of dopamine reuptake, but conversely it is a much stronger serotonin reuptake inhibitor than cocaine, resulting in a significantly altered pharmacological profile in animal studies.
