CP-39,332
CP-39,332 is a drug which acts as a serotonin-norepinephrine reuptake inhibitor. Tametraline (1''R'',4''S''-), CP-24,442 (1''S'',4''R''-), CP-22,185 (''cis''-), and CP-22,186 (''trans''-) are stereoisomers of the compound and show varying effects on monoamine reuptake. None of them were ever marketed. See also * Tametraline * Sertraline * 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.

Drug
A drug is any chemical substance that causes a change in an organism's physiology or psychology when consumed. Drugs are typically distinguished from food and substances that provide nutritional support. Consumption of drugs can be via insufflation (medicine), inhalation, drug injection, injection, smoking, ingestion, absorption (skin), absorption via a dermal patch, patch on the skin, suppository, or sublingual administration, dissolution under the tongue. In pharmacology, a drug is a chemical substance, typically of known structure, which, when administered to a living organism, produces a biological effect. A pharmaceutical drug, also called a medication or medicine, is a chemical substance used to pharmacotherapy, treat, cure, preventive healthcare, prevent, or medical diagnosis, diagnose a disease or to promote well-being. Traditionally drugs were obtained through extraction from medicinal plants, but more recently also by organic synthesis. Pharmaceutical drugs may be used ...

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.

Stereoisomer
In stereochemistry, stereoisomerism, or spatial isomerism, is a form of isomerism in which molecules have the same molecular formula and sequence of bonded atoms (constitution), but differ in the three-dimensional orientations of their atoms in space. This contrasts with structural isomers, which share the same molecular formula, but the bond connections or their order differs. By definition, molecules that are stereoisomers of each other represent the same structural isomer. Enantiomers Enantiomers, also known as optical isomers, are two stereoisomers that are related to each other by a reflection: they are mirror images of each other that are non-superposable. Human hands are a macroscopic analog of this. Every stereogenic center in one has the opposite configuration in the other. Two compounds that are enantiomers of each other have the same physical properties, except for the direction in which they rotate polarized light and how they interact with different optical isom ...

Monoamine
Monoamine neurotransmitters are neurotransmitters and neuromodulators that contain one amino group connected to an aromatic ring by a two-carbon chain (such as -CH2-CH2-). Examples are dopamine, norepinephrine and serotonin. All monoamines are derived from aromatic amino acids like phenylalanine, tyrosine, and tryptophan by the action of aromatic amino acid decarboxylase enzymes. They are deactivated in the body by the enzymes known as monoamine oxidases which clip off the amine group. Monoaminergic systems, i.e., the networks of neurons that use monoamine neurotransmitters, are involved in the regulation of processes such as emotion, arousal, and certain types of memory. It has also been found that monoamine neurotransmitters play an important role in the secretion and production of neurotrophin-3 by astrocytes, a chemical which maintains neuron integrity and provides neurons with trophic support. Drugs used to increase or reduce the effect of monoamine neurotransmitters are u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reuptake
Reuptake is the reabsorption of a neurotransmitter by a neurotransmitter transporter located along the plasma membrane of an axon terminal (i.e., the pre-synaptic neuron at a synapse) or glial cell after it has performed its function of transmitting a neural impulse. Reuptake is necessary for normal synaptic physiology because it allows for the recycling of neurotransmitters and regulates the level of neurotransmitter present in the synapse, thereby controlling how long a signal resulting from neurotransmitter release lasts. Because neurotransmitters are too large and hydrophilic to diffuse through the membrane, specific transport proteins are necessary for the reabsorption of neurotransmitters. Much research, both biochemical and structural, has been performed to obtain clues about the mechanism of reuptake. Protein structure The first primary sequence of a reuptake protein was published in 1990. The technique for protein sequence determination relied upon the purification, ...

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 ...

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 ...
