RTI-171
(–)-2β-(3-Methylisoxazol-5-yl)-3β-(p-tolyl)tropane (RTI-''4229''-171) is a phenyltropane derivative which acts as a selective dopamine reuptake inhibitor, with a relatively slow onset of action and short duration of effects found in animal studies. However, other studies have shown it to have the most pronounced effects in terms of speed of onset and rate of stimulation among many differing phenyltropanes.

O-4210
O-4210 is a drug developed by Organix Inc which acts as a selective dopamine reuptake inhibitor, with good selectivity over the serotonin transporter but its activity at the noradrenaline transporter is not known. It is a thiatropane derivative, related in chemical structure to phenyltropane derivatives such as RTI-126 and RTI-171, but with the amine nitrogen replaced by sulfur, demonstrating that this nitrogen only plays a minor contribution to receptor binding, in a similar manner to the related oxatropane tropoxane.

Tolyl
In organic chemistry, tolyl groups are functional groups related to toluene. They have the general formula , the change of the relative position of the methyl and the R substituent on the aromatic ring can generate three possible structural isomers 1,2 (''ortho''), 1,3 (''meta''), and 1,4 (''para''). Tolyl groups are aryl groups which are commonly found in the structure of diverse chemical compounds. They are considered nonpolar In chemistry, polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole moment, with a negatively charged end and a positively charged end. Polar molecules must contain one or more polar ... and Hydrophobe, hydrophobic groups. The functionalization to include tolyl groups into compounds is often done by Williamson ether synthesis, Williamson etherification, using tolyl alcohols as reagents, or by Cross-coupling reaction, C-C coupling reactions. Tolyl sulfonates are excellent leaving groups ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phenyltropane
Phenyltropanes (PTs) were originally developed to reduce cocaine addiction and dependency. In general these compounds act as inhibitors of the plasmalemmal monoamine reuptake transporters. Although RTI holds a strong position in this field, they are not the ''only'' researchers that have prepared these analogues. This research has spanned beyond the last couple decades, and has picked up its pace in recent times, creating numerous phenyltropanes as research into cocaine analogues garners interest to treat addiction. Uses Addiction The phenyltropane compounds were initially discovered by R. Clarke et al. during research to try and dissociate the stimulant properties of cocaine from its abuse and dependence liability. The first simple phenyltropanes to be made (WIN 35065-2 and WIN 34,428) were shown to be active in behavioral assays only for the ββ-isomers. The activity of the corresponding αβ-isomers was disappointing. It was later shown that WIN 35065-2 and WIN 34,428 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dopamine Reuptake Inhibitor
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 l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RTI-126
RTI-126 (RTI-''4229''-126 or (–)-2β-(1,2,4-oxadiazol-5-methyl)-3β-phenyltropane) is a phenyltropane derivative which acts as a potent monoamine reuptake inhibitor and stimulant drug, and has been sold as a designer drug. It is around 5 times more potent than cocaine at inhibiting monoamine reuptake ''in vitro'', but is relatively unselective. It binds to all three monoamine transporters, although still with some selectivity for the dopamine transporter. RTI-126 has a fast onset of effects and short duration of action, and its pharmacological profile in animals is among the closest to cocaine itself out of all the drugs in the RTI series. Its main application in scientific research has been in studies investigating the influence of pharmacokinetics on the abuse potential of stimulant drugs, with its rapid entry into the brain thought to be a key factor in producing its high propensity for development of dependence in animals. The structurally related compound (–)-2β-(3-met ... [...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, u ...
