[11C]ME@HAPTHI is a radiotracer of the norepinephrine transporter for positron emission tomography. [1]
Reuptake is the reabsorption of a neurotransmitter by a neurotransmitter transporter located along the plasma membrane of an axon terminal or glial cell after it has performed its function of transmitting a neural impulse.
Serotonin–norepinephrine reuptake inhibitors (SNRIs) are a class of antidepressant medications used to treat major depressive disorder (MDD), anxiety disorders, social phobia, chronic neuropathic pain, fibromyalgia syndrome (FMS), and menopausal symptoms. Off-label uses include treatments for attention-deficit hyperactivity disorder (ADHD), and obsessive–compulsive disorder (OCD). SNRIs are monoamine reuptake inhibitors; specifically, they inhibit the reuptake of serotonin and norepinephrine. These neurotransmitters are thought to play an important role in mood regulation. SNRIs can be contrasted with the selective serotonin reuptake inhibitors (SSRIs) and norepinephrine reuptake inhibitors (NRIs), which act upon single neurotransmitters.
A norepinephrine reuptake inhibitor or noradrenaline reuptake inhibitor or adrenergic reuptake inhibitor (ARI), is a type of drug that acts as a reuptake inhibitor for the neurotransmitters norepinephrine (noradrenaline) and epinephrine (adrenaline) by blocking the action of the norepinephrine transporter (NET). This in turn leads to increased extracellular concentrations of norepinephrine and epinephrine and therefore can increase adrenergic neurotransmission.
The norepinephrine transporter (NET), also known as noradrenaline transporter (NAT), is a protein that in humans is encoded by the solute carrier family 6 member 2 (SLC6A2) gene.
Neurotransmitter transporters are a class of membrane transport proteins that span the cellular membranes of neurons. Their primary function is to carry neurotransmitters across these membranes and to direct their further transport to specific intracellular locations. There are more than twenty types of neurotransmitter transporters.
Naphthylaminopropane, also known as naphthylisopropylamine (NIPA), is an experimental drug that was under investigation for the treatment of alcohol and stimulant addiction.
Solute carrier family 22 member 3 (SLC22A3) also known as the organic cation transporter 3 (OCT3) or extraneuronal monoamine transporter (EMT) is a protein that in humans is encoded by the SLC22A3 gene.
Nisoxetine, originally synthesized in the Lilly research laboratories during the early 1970s, is a potent and selective inhibitor for the reuptake of norepinephrine (noradrenaline) into synapses. It currently has no clinical applications in humans, although it was originally researched as an antidepressant. Nisoxetine is now widely used in scientific research as a standard selective norepinephrine reuptake inhibitor. It has been used to research obesity and energy balance, and exerts some local analgesia effects.
Reuptake inhibitors (RIs) are a type of reuptake modulators. It is a drug that inhibits the plasmalemmal transporter-mediated reuptake of a neurotransmitter from the synapse into the pre-synaptic neuron. This leads to an increase in extracellular concentrations of the neurotransmitter and an increase in neurotransmission. Various drugs exert their psychological and physiological effects through reuptake inhibition, including many antidepressants and psychostimulants.
In genetics, rs5569 is a genetic variant. It is a single nucleotide polymorphism (SNP) in the SLC6A2 gene in exon 9. This gene codes the norepinephrine transporter. The SNP is a silent substitution and the nucleotides of both variants code a threonine amino acid.
Meprylcaine is a local anesthetic with stimulant properties that is structurally related to dimethocaine.
5-Iodo-2-aminoindane (5-IAI) is an entactogen drug of the 2-aminoindane group. Human anecdotal reports suggest that it is entactogenic but produces little euphoria or stimulation.
A dopamine releasing agent (DRA) is a type of drug which induces the release of dopamine in the body and/or brain.
A norepinephrine–dopamine releasing agent (NDRA) is a type of drug which induces the release of norepinephrine and dopamine in the body and/or brain.
A norepinephrine–dopamine reuptake inhibitor (NDRI) is a drug used for the treatment of clinical depression, attention deficit hyperactivity disorder (ADHD), narcolepsy, and the management of Parkinson's disease. The drug acts as a reuptake inhibitor for the neurotransmitters norepinephrine and dopamine by blocking the action of the norepinephrine transporter (NET) and the dopamine transporter (DAT), respectively. This in turn leads to increased extracellular concentrations of both norepinephrine and dopamine and, therefore, an increase in adrenergic and dopaminergic neurotransmission.
Lortalamine (LM-1404) is an antidepressant which was synthesized in the early 1980s. It acts as a potent and highly selective norepinephrine reuptake inhibitor. Lortalamine was under development for clinical use but was shelved, likely due to the finding that it produced ocular toxicity in animals. It has been used to label the norepinephrine transporter in positron emission tomography studies.
A monoamine reuptake inhibitor (MRI) is a drug that acts as a reuptake inhibitor of one or more of the three major monoamine neurotransmitters serotonin, norepinephrine, and dopamine by blocking the action of one or more of the respective monoamine transporters (MATs), which include the serotonin transporter (SERT), norepinephrine transporter (NET), and dopamine transporter (DAT). This in turn results in an increase in the synaptic concentrations of one or more of these neurotransmitters and therefore an increase in monoaminergic neurotransmission.
WY-46824 is a norepinephrine-dopamine reuptake inhibitor related to venlafaxine. It was disclosed by Paige Mahaney and colleagues from Wyeth in 2008. The compound was mentioned in an earlier article from 2007 but was not the main focus of that study.
Methamnetamine is a triple monoamine releasing agent and N-methyl analog of the non-neurotoxic experimental drug naphthylaminopropane and the naphthalene analog of methamphetamine. It has been sold online as a designer drug.
ortho-Methylphenylpiperazine (also known as oMPP, oMePP, 1-(2-methylphenyl)piperazine, 2-MPP, and 2-MePP) is a psychoactive designer drug of the phenylpiperazine group. It acts as a serotonin–norepinephrine–dopamine releasing agent (SNDRA), with EC50 values for induction of monoamine release of 175 nM for serotonin, 39.1 nM for norepinephrine, and 296–542 nM for dopamine. As such, it has about 4.5-fold preference for induction of norepinephrine release over serotonin, and about 7.6- to 13.9-fold preference for induction of norepinephrine release over dopamine.
