(-)-2β-Carbomethoxy-3β-(4-fluorophenyl)tropane
(–)-2-β-Carbomethoxy-3-β-(4-fluorophenyl)tropane (β-CFT, WIN 35,428) is a stimulant drug used in scientific research. CFT is a phenyltropane based dopamine reuptake inhibitor and is structurally derived from cocaine. It is around 3-10x more potent than cocaine and lasts around 7 times longer based on animal studies. While the Armstrong's acid, naphthalenedisulfonate salt is the most commonly used form in scientific research due to its high solubility in water, the free base and hydrochloride salts are known compounds and can also be produced. The tartrate is another salt form that is reported. Uses CFT was first reported by Clarke and co-workers in 1973. This drug is known to function as a "positive reinforcer" (although it is less likely to be self-administered by rhesus monkeys than cocaine). Tritiated CFT is frequently used to map binding of novel ligands to the Dopamine active transporter, DAT, although the drug also has some Serotonin transporter, SERT affinity. Isoto ...

Methylecgonidine
Methylecgonidine (anhydromethylecgonine; anhydroecgonine methyl ester; AEME) is a chemical intermediate derived from ecgonine or cocaine. Methylecgonidine is a pyrolysis product formed when crack cocaine is smoked, making this substance a useful biomarker to specifically test for use of crack cocaine, as opposed to powder cocaine which does not form methylecgonidine as a metabolite. Methylecgonidine has a relatively short half-life of 18–21 minutes, after which it is metabolised to ecgonidine, meaning that the relative concentrations of the two compounds can be used to estimate how recently crack cocaine has been smoked. Methylecgonidine has been shown to be specifically more harmful to the body than other byproducts of cocaine; for example to the heart, lungs & liver. The toxicity is due to a partial agonist effect at M1 and M3 muscarinic receptors, leading to DNA fragmentation and neuronal death by apoptosis. AEME is also used in scientific research for the manufacture of p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Armstrong's Acid
Armstrong's acid (naphthalene-1,5-disulfonic acid) is a fluorescent organic compound with the formula C10H6(SO3H)2. It is one of several isomers of naphthalenedisulfonic acid. It a colorless solid, typically obtained as the tetrahydrate. Like other sulfonic acids, it is a strong acid. It is named for British chemist Henry Edward Armstrong. Production and use It is prepared by disulfonation of naphthalene with oleum: :C10H8 + 2 SO3 → C10H6(SO3H)2 Further sulfonation gives The 1,3,5-trisulfonic acid derivative.Gerald Booth "Naphthalene Derivatives" in Ullmann's Encyclopedia of Industrial Chemistry, 2005, Wiley-VCH, Weinheim. . Reactions and uses Fusion of Armstrong's acid in NaOH gives the disodium salt of 1,5-dihydroxynaphthalene, which can be acidified to give the diol. The intermediate in this hydrolysis, 1-hydroxynaphthalene-5-sulfonic acid, is also useful. Nitration gives nitrodisulfonic acids, which are precursors to amino derivatives. The disodium salt is so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ecgonine
Ecgonine (tropane derivative) is a tropane alkaloid found naturally in coca leaves. It has a close structural relation to cocaine: it is both a metabolite and a precursor, and as such, it is a controlled substance in many jurisdictions, as are some substances which can be used as precursors to ecgonine itself. Structurally, ecgonine is a cycloheptane derivative with a nitrogen bridge. It is obtained by hydrolysis of cocaine with acids or alkalis, and crystallizes with one molecule of water, the crystals melting at 198–199 °C. It is levorotary, and on warming with alkalis gives iso-ecgonine, which is dextrorotary. It is a tertiary base, and has the properties of an acid and an alcohol. It is the carboxylic acid corresponding to tropine, for it yields the same products on oxidation, and by treatment with phosphorus pentachloride is converted into anhydroecgonine, C9H13NO2, which, when heated to 280 °C with hydrochloric acid, eliminates carbon dioxide and yields tro ...

Dopamine Reuptake Inhibitors
A dopamine reuptake inhibitor (DRI) is a class of drug which acts as a reuptake inhibitor of the monoamine neurotransmitter dopamine by blocking the action of the dopamine transporter (DAT). Reuptake inhibition is achieved when extracellular dopamine not absorbed by the postsynaptic neuron is blocked from re-entering the presynaptic neuron. This results in increased extracellular concentrations of dopamine and increase in dopaminergic neurotransmission. DRIs are used in the treatment of attention-deficit hyperactivity disorder (ADHD) and narcolepsy for their psychostimulant effects, and in the treatment of obesity and binge eating disorder for their appetite suppressant effects. They are sometimes used as antidepressants in the treatment of mood disorders, but their use as antidepressants is limited given that strong DRIs have a high abuse potential and legal restrictions on their use. Lack of dopamine reuptake and the increase in extracellular levels of dopamine have been linked ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tropanes
Tropane alkaloids are a class of bicyclic .2.1alkaloids and secondary metabolites that contain a tropane ring in their chemical structure. Tropane alkaloids occur naturally in many members of the plant family Solanaceae. Certain tropane alkaloids such as cocaine and scopolamine are notorious for their psychoactive effects, related usage and cultural associations. Particular tropane alkaloids such as these have pharmacological properties and can act as anticholinergics or stimulants. Classification Anticholinergics Anticholinergic drugs and deliriants: * Atropine, racemic hyoscyamine, from the deadly nightshade (''Atropa belladonna'') * Hyoscyamine, the ''levo''-isomer of atropine, from henbane (''Hyoscyamus niger''), mandrake (''Mandragora officinarum'') and the sorcerers' tree (''Latua pubiflora''). * Scopolamine, from henbane and ''Datura'' species (Jimson weed) All three acetylcholine-inhibiting chemicals can also be found in the leaves, stems, and flowers in varying, un ...

List Of Cocaine Analogues
This is a list of cocaine analogues. A cocaine analogue is an (usually) artificial construct of a novel chemical compound from (often the starting point of natural) cocaine's molecular structure, with the result product sufficiently similar to cocaine to display similarity in, but alteration to, its chemical function. Within the scope of analogous compounds created from the structure of cocaine, so named "cocaine analogues" retain 3''β''-benzoyloxy or similar functionality (the term specifically used usually distinguishes from phenyltropanes, but in the broad sense generally, as a category, includes them) on a tropane skeleton, as compared to other stimulants of the kind. Many of the semi-synthetic cocaine analogues ''proper'' which have been made & studied have consisted of among the nine following classes of compounds: * stereoisomers of cocaine * 3''β''-phenyl ring substituted analogues * 2''β''-substituted analogues * ''N''-modified analogues of cocaine * 3''β''-carbamoyl a ...

WIN 35,065-2
Troparil (also known as (–)-2β-Carbomethoxy-3β-phenyltropane, WIN 35,065-2, or β-CPT) is a stimulant drug used in scientific research. Troparil is a phenyltropane-based dopamine reuptake inhibitor (DRI) that is derived from methylecgonidine. Troparil is a few times more potent than cocaine as a dopamine reuptake inhibitor, but is less potent as a serotonin reuptake inhibitor, and has a duration spanning a few times longer, since the phenyl ring is directly connected to the tropane ring through a non-hydrolyzable carbon-carbon bond. The lack of an ester linkage removes the local anesthetic action from the drug, so troparil is a pure stimulant. This change in activity also makes troparil slightly less cardiotoxic than cocaine. The most commonly used form of troparil is the tartrate salt, but the hydrochloride and naphthalenedisulfonate salts are also available, as well as the free base. Background The first known published synthesis of troparil and the related compound WIN 3 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RTI-55
RTI(-''4229'')-55, also called RTI-55 or iometopane, is a phenyltropane-based psychostimulant used in scientific research and in some medical applications. This drug was first cited in 1991. RTI-55 is a non-selective dopamine reuptake inhibitor derived from methylecgonidine. However, more selective analogs are derived by conversion to "pyrrolidinoamido" RTI-229, for instance. Due to the large bulbous nature of the weakly electron withdrawing iodo halogen atom, RTI-55 is the most strongly serotonergic of the simple ''para''-substituted troparil based analogs. In rodents RTI-55 actually caused death at a dosage of 100 mg/kg, whereas RTI-51 and RTI-31 did not. Another notable observation is the strong propensity of RTI-55 to cause locomotor activity enhancements, although in an earlier study, RTI-51 was actually even stronger than RTI-55 in shifting baseline LMA. This observation serves to highlight the disparities that can arise between studies. RTI-55 is one of the most pote ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Federal Analog Act
The Federal Analogue Act, , is a section of the United States Controlled Substances Act passed in 1986 which allows any chemical "substantially similar" to a controlled substance listed in Controlled Substances Act#Schedule I controlled substances, Schedule I or Controlled Substances Act#Schedule II controlled substances, II to be treated as if it were listed in Schedule I, but only if intended for human consumption. These similar substances are often called designer drugs. The law's constitutionality has been questioned by now Supreme Court Justice Neil Gorsuch; its broad reach has been used to successfully prosecute possession of chemicals openly sold as dietary supplements and naturally contained in foods such as chocolate. Definition (32) *(A) Except as provided in subparagraph (C), the term ''controlled substance analogue'' means a substance - **(i) the chemical structure of which is substantially similar to the chemical structure of a controlled substance in schedule I or I ...

MDPV
Methylenedioxypyrovalerone (MDPV) is a stimulant of the cathinone class that acts as a norepinephrine–dopamine reuptake inhibitor (NDRI). It was first developed in the 1960s by a team at Boehringer Ingelheim. Its activity at the dopamine transporter is six times stronger than at the norepinephrine transporter and it is virtually inactive at the serotonin transporter. MDPV remained an obscure stimulant until around 2004 when it was reportedly sold as a designer drug. In the USA, products containing MDPV and labeled as bath salts were sold as recreational drugs in gas stations, similar to the marketing for Spice and K2 as incense, until it was banned in 2011. Appearance The hydrochloride salt exists as a very fine crystalline powder; it is hygroscopic and thus tends to form clumps, resembling something like powdered sugar. Its color can range from pure white to a yellowish-tan and has a slight odor that strengthens as it colors. Impurities are likely to consist of either pyrr ...
