Tametraline
Tametraline (CP-24,441) is the parent of a series of chemical compounds investigated at Pfizer that eventually led to the development of sertraline (CP-51,974-1). Sertraline has been called "3,4-dichloro-tametraline". This is correct but it is an oversimplification in the sense that sertraline is the ''S'',''S''-isomer whereas tametraline is the 1''R'',4''S''-stereoisomer. 1''R''-Methylamino-4''S''-phenyl-tetralin is a potent inhibitor of norepinephrine uptake in rat brain synaptosomes, reverses reserpine induced hypothermia in mice, and blocks uptake of 3H-Norepinephrine into rat heart. Tametraline is a norepinephrine-dopamine reuptake inhibitor. Indatraline is an indanamine homolog of tetralin-based tametraline, although in the case of indatraline the product is pm-dichlorinated.

Dasotraline
Dasotraline (INN; former developmental code name SEP-225,289) is a serotonin-norepinephrine-dopamine reuptake inhibitor (SNDRI) that was under development by Sunovion for the treatment of attention-deficit hyperactivity disorder (ADHD) and binge eating disorder (BED). Structurally, dasotraline is a stereoisomer of desmethylsertraline (DMS), which is an active metabolite of the marketed selective serotonin reuptake inhibitor (SSRI) antidepressant sertraline (Zoloft). Adverse Effects In phase I clinical trials for ADHD, test subjects reported the following side effects: * Loss of appetite * Dehydration * Dry mouth * Nausea * Insomnia * Anxiety * Panic attacks * Headaches History In 2017, the U.S. Food and Drug Administration accepted Sunovion's New Drug Application (NDA) for review for the treatment of ADHD; however, the NDA was ultimately rejected citing the need for additional studies to determine efficacy and tolerability. In July 2019, Sunovion’s NDA for the treatment o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Desmethylsertraline
Desmethylsertraline (DMS), also known as norsertraline, is an active metabolite of the antidepressant drug sertraline. Like sertraline, desmethylsertraline acts as a monoamine reuptake inhibitor, and may be responsible for some of its parent's therapeutic benefits; however, the effects of DMS's main activity of increasing serotonin levels via binding to the serotonin transporter appears to be negligible as in vivo testing showed no measurable change in brain activity despite a nearly 20-fold increase in DMS blood levels compared to the EC50 (i.e. the amount required to achieve the desired effect in 50% of the population) of its parent drug sertraline. DMS is significantly less potent relative to sertraline as a serotonin reuptake inhibitor (''K''i = 76 nM vs. 3 nM, respectively), but conversely, is more balanced as a monoamine reuptake inhibitor ( 5-HT (''K''i) = 76 nM; NE (''K''i) = 420 nM; DA (''K''i) = 440 nM), which has the effective result of DMS con ...

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 ...

Sertraline
Sertraline, sold under the brand name Zoloft among others, is an antidepressant of the selective serotonin reuptake inhibitor (SSRI) class. The efficacy of sertraline for depression is similar to that of other antidepressants, and the differences are mostly confined to side effects. Sertraline is better tolerated than the older tricyclic antidepressants, and it may work better than fluoxetine for some subtypes of depression. Sertraline is effective for panic disorder, social anxiety disorder, generalized anxiety disorder, and obsessive–compulsive disorder (OCD). However, for OCD, cognitive behavioral therapy, particularly in combination with sertraline, is a better treatment. Although approved for post-traumatic stress disorder, sertraline leads to only modest improvement in this condition. Sertraline also alleviates the symptoms of premenstrual dysphoric disorder and can be used in sub-therapeutic doses or intermittently for its treatment. Sertraline shares the common si ...

Nefopam
Nefopam, sold under the brand name Acupan among others, is a centrally acting, non-opioid painkilling medication, that is primarily used to treat moderate to severe pain. Nefopam acts in the brain and spinal cord to relieve pain via novel mechanisms: antinociceptive effects from triple monoamine reuptake inhibition, and antihyperalgesic activity through modulation of glutamatergic transmission. Medical uses Nefopam is effective for prevention of shivering during surgery or recovery from surgery. Nefopam was significantly more effective than aspirin as an analgesic in one clinical trial, although with a greater incidence of side effects such as sweating, dizziness and nausea, especially at higher doses. The estimated relative potency of nefopam to morphine indicates that 20 mg of nefopam HCl is the approximate analgesic equal of 12 mg of morphine with comparable analgesic efficacy to morphine, or oxycodone, while nefopam tends to produce fewer side effects, does not pr ...

Lometraline
Lometraline (INN; developmental code name CP-14,368) is a drug and an aminotetralin derivative. A structural modification of tricyclic neuroleptics, lometraline was originally patented by Pfizer as an antipsychotic, tranquilizer, and antiparkinsonian agent. However, it was instead later studied as a potential antidepressant and/or anxiolytic agent, though clinical studies revealed no psychoactivity at the doses used and further investigation was suspended. Further experimental modifications of the chemical structure of lometraline resulted in the discovery of tametraline, a potent inhibitor of the reuptake of dopamine and norepinephrine, which in turn led to the discovery of the now widely popular antidepressant sertraline, a selective serotonin reuptake inhibitor Selective serotonin reuptake inhibitors (SSRIs) are a class of drugs that are typically used as antidepressants in the treatment of major depressive disorder, anxiety disorders, and other psychological condition ...

JNJ-7925476
JNJ-7925476 is a triple reuptake inhibitor antidepressant discovered by Johnson & Johnson, but never marketed. These molecules were first prepared by Bruce E. Maryanoff and coworkers during the late 1970s–1980s. The structure is a pyrroloisoquinoline core, with an overlaid benzhydryl motif. Incorporating the pyrrolidino ring onto the tetrahydroisoquinoline scaffolding markedly improves potency, although this only works for one of the available stereoisomers. JNJ-7925476 is a racemic preparation of the more potent diastereomer. Of these enantiomers, the eutomer is the (6''R'',10b''S'') stereoisomer, known as JNJ-39836966, and the distomer, (6''S'',10b''R''), is JNJ-39836732 There is some confusion over the nomenclature and ''cis''/''trans'' isomeric relationship at the piperidine ring. The compounds as depicted have the carbon of the pyrrolidine carbon and the phenyl ''cis'', but Maryanoff and coworkers are of the opinion that the compound is ''trans''. (see abstract) ...
