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.

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 ...

Alkaloid
Alkaloids are a class of basic, naturally occurring organic compounds that contain at least one nitrogen atom. This group also includes some related compounds with neutral and even weakly acidic properties. Some synthetic compounds of similar structure may also be termed alkaloids. In addition to carbon, hydrogen and nitrogen, alkaloids may also contain oxygen, sulfur and, more rarely, other elements such as chlorine, bromine, and phosphorus.Chemical Encyclopedia: alkaloids xumuk.ru Alkaloids are produced by a large variety of organisms including , , Medicinal plant, plants, an ...

The Journal Of Pharmacology And Experimental Therapeutics
The ''Journal of Pharmacology and Experimental Therapeutics'' (a.k.a. JPET) is a peer-reviewed scientific journal covering pharmacology. It has been published since 1909 by the American Society for Pharmacology and Experimental Therapeutics (ASPET). The journal publishes mainly original research articles, and accepts papers covering all aspects of the interactions of chemicals with biological systems. John Jacob Abel founded ASPET in December 1908 when he invited 18 pharmacologists to his laboratory in order to organize a new society. At the end of the meeting Abel announced the establishment of JPET. According to the ''Journal Citation Reports'', the journal received a 2021 impact factor of 4.4. Further readingPharm. Exp.

Mitsunobu Reaction
The Mitsunobu reaction is an organic reaction that converts an alcohol into a variety of functional groups, such as an ester, using triphenylphosphine and an azodicarboxylate such as diethyl azodicarboxylate (DEAD) or diisopropyl azodicarboxylate (DIAD). Although DEAD and DIAD are most commonly used, there are a variety of other azodicarboxylates available which facilitate an easier workup and/or purification and in some cases, facilitate the use of more basic nucleophiles. It was discovered by Oyo Mitsunobu (1934–2003). Typical protocol is to add the phosphine and azodicarboxylate together at −10 °C, typically in THF or toluene, until a white precipitate forms. This white, cloudy suspension is the ylide. Then a solution of the nucleophile and alcohol are added together and the reaction can be, and in many cases is, heated to reflux. The alcohol reacts with the phosphine to create a good leaving group then undergoes an inversion of stereochemistry in classic SN2 fashion ...

Benzoylecgonine
Benzoylecgonine is the main metabolite of cocaine, formed by the liver and excreted in the urine. It is the compound tested for in most cocaine urine drug screens. Pharmacokinetics Chemically, benzoylecgonine is the benzoate ester of ecgonine. It is a primary metabolite of cocaine, and is pharmacologically inactive. Urinalysis Benzoylecgonine is the compound tested for in most substantive cocaine drug urinalyses. It is the corresponding carboxylic acid of cocaine, its methyl ester. It is formed in the liver by the metabolism of cocaine by hydrolysis, catalysed by carboxylesterases, and subsequently excreted in the urine. Presence in drinking water Benzoylecgonine is sometimes found in drinking water supplies. In 2005, scientists found surprisingly large quantities of benzoylecgonine in Italy's Po River and used its concentration to estimate the number of cocaine users in the region. In 2006, a similar study was performed in the Swiss ski town of Saint-Moritz using wastewater to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indatraline
Indatraline (Lu 19-005) is a non- selective monoamine transporter inhibitor shown to block the reuptake of dopamine, norepinephrine, and serotonin, with effects similar to those of cocaine. The effects have been shown to have a slower onset and longer duration than cocaine, suggesting that the compound may, along with similar compounds, be used for the treatment of cocaine addiction. LU 19-005 has been shown to block the action of methamphetamine and MDMA in laboratory experiments. Superposition should make it possible to see there is at least a fundamental relationship between the pharmacophore of indatraline and various phenyltropanes. Methylation If indatraline is ''N''-alkylated at the amino group, it is possible to slow the onset of action so that it is not until ''N''-demethylation occurs that the molecules become active. ''N''-methylindatraline has a much longer duration than indatraline because norindatraline is inactive, whereas demethylating ''N''-methylindatraline doe ...

Tropane Alkaloid
Tropane alkaloids are a class of bicyclic [3.2.1] alkaloids 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, racemate, 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''). * Hyoscine hydrobromide, Scopolamine, from henbane and ''Datura'' species (Jimson weed) All three acetylcholine-inhibiting chemicals can also be found in the leave ...

Tropane Alkaloids Found In Erythroxylum Coca
Tropane is a nitrogenous 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 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 .2.1ctane (tropane without the ''N''-methyl group) is known as nortropane or nor-tropane. See also * Phenyltropane * Tropane alkaloid * Tropine Tropine is a derivative of tropane containing a hydroxyl group at the third carbon. It is also called 3-tropanol. Tropine is a central building block of many chemicals active in the nervous system, including tropane alkaloids. Some of these comp . ...
