8-OH-DPAT is a research chemical of the aminotetralin chemical class which was developed in the 1980s and has been widely used to study the function of the 5-HT 1A receptor.It was one of the first major 5-HT 1A receptor full agonists to have been discovered.
5-OH-DPAT is a synthetic compound that acts as a dopamine receptor agonist with selectivity for the D 2 receptor and D 3 receptor subtypes. [ 1 ] [ 2 ] Only the ( S )-enantiomer is active as an agonist, with the ( R )-enantiomer being a weak antagonist at D 2 receptors. [ 3 ]
7-OH-DPAT is a synthetic compound that acts as a dopamine receptor agonist with reasonable selectivity for the D 3 receptor subtype, [2] [3] [4] and low affinity for serotonin receptors, unlike its structural isomer 8-OH-DPAT. [5] [6] [7] 7-OH-DPAT is self-administered in several animal models, and is used to study its addiction effects to cocaine.
In 1942, responsibility for enforcing federal firearms laws was given to the ATU. In the early 1950s, the Bureau of Internal Revenue was renamed "Internal Revenue Service" (IRS), [6] and the ATU was given the additional responsibility of enforcing federal tobacco tax laws. At this time, the name of the ATU was changed to the Alcohol and Tobacco ...
Benzothiophene. 3-APBT, an example of a substituted benzothiophene.. The substituted benzothiophenes are a class of chemical compounds based on benzothiophene. [1] [2] They are closely related to the substituted benzofurans, substituted tryptamines, and to other chemical groups such as the substituted benzodioxoles (or methylenedioxy phenyl compounds).
SB269652 is an experimental dopamine D 2 and D 3 receptor negative allosteric modulator. [1] [2] It is of interest in the potential development of novel antipsychotics for treatment of schizophrenia with reduced side effects, such as extrapyramidal symptoms.
An antenna tuner, a matchbox, transmatch, antenna tuning unit (ATU), antenna coupler, or feedline coupler is a device connected between a radio transmitter or receiver and its antenna to improve power transfer between them by matching the impedance of the radio to the antenna's feedline. Antenna tuners are particularly important for use with ...
The activation function of a node in an artificial neural network is a function that calculates the output of the node based on its individual inputs and their weights. Nontrivial problems can be solved using only a few nodes if the activation function is nonlinear .
