5-HT7 Receptor
The 5-HT7 receptor is a member of the GPCR superfamily of cell surface receptors and is activated by the neurotransmitter serotonin (5-hydroxytryptamine, 5-HT) The 5-HT7 receptor is coupled to Gs (stimulates the production of the intracellular signaling molecule cAMP) and is expressed in a variety of human tissues, particularly in the brain, the gastrointestinal tract, and in various blood vessels. This receptor has been a drug development target for the treatment of several clinical disorders. The 5-HT7 receptor is encoded by the ''HTR7'' gene, which in humans is transcribed into 3 different splice variants. Function When the 5-HT7 receptor is activated by serotonin, it sets off a cascade of events starting with release of the stimulatory G protein Gs from the GPCR complex. Gs in turn activates adenylate cyclase which increases intracellular levels of the second messenger cAMP. The 5-HT7 receptor plays a role in smooth muscle relaxation within the vasculature a ...

AS-19 (drug)
AS-19 is a substance which acts as a potent agonist at the 5-HT7 receptor, with an IC50 of 0.83nM. It reverses the amnesia induced by drugs such as scopolamine and dizocilpine Dizocilpine (INN), also known as MK-801, is a pore blocker of the ''N''-Methyl-D-aspartate (NMDA) receptor, a glutamate receptor, discovered by a team at Merck in 1982. Glutamate is the brain's primary excitatory neurotransmitter. The channel is ... and improves long-term memory acquisition, but inhibits short-term memory formation.

E-55888
E-55888 is a drug developed by Esteve, which acts as a potent and selective full agonist at the 5HT7 serotonin receptor, and is used for investigating the role of 5-HT7 receptors in the perception of pain. When administered by itself, E-55888 is anti- hyperalgesic but not analgesic, but when administered alongside morphine Morphine is a strong opiate that is found naturally in opium, a dark brown resin in poppies ('' Papaver somniferum''). It is mainly used as a pain medication, and is also commonly used recreationally, or to make other illicit opioids. Ther ..., E-55888 was found to significantly increase the analgesic effects.

LP-12
LP-12 is a drug which acts as a potent agonist at the 5HT7 serotonin receptor, with very high selectivity over other tested receptor subtypes such as the serotonin 5-HT1A and 5-HT2A, and the dopamine D2 receptor. It has been used to research the involvement of the 5-HT7 receptor in as yet poorly understood processes such as allodynia and hyperalgesia.

LP-44
LP-44 is a drug which acts as a potent and selective agonist at the 5HT7 serotonin receptor. While LP-44 is less selective than the related compound LP-12, it has been more widely used in research and has been used to show the complex role of 5-HT7 receptors in several aspects of brain function, including regulation of the sleep-wake cycle and roles in stress, learning and memory.

Agonist
An agonist is a chemical that activates a receptor to produce a biological response. Receptors are cellular proteins whose activation causes the cell to modify what it is currently doing. In contrast, an antagonist blocks the action of the agonist, while an inverse agonist causes an action opposite to that of the agonist. Etymology From the Greek αγωνιστής (agōnistēs), contestant; champion; rival < αγων (agōn), contest, combat; exertion, struggle < αγω (agō), I lead, lead towards, conduct; drive Types of agonists Receptors can be activated by either agonists (such as[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Serotonin Receptor
5-HT receptors, 5-hydroxytryptamine receptors, or serotonin receptors, are a group of G protein-coupled receptor and ligand-gated ion channels found in the Central nervous system, central and peripheral nervous systems. They mediate both Neurotransmitter#Excitatory and inhibitory, excitatory and inhibitory Synaptic transmission, neurotransmission. The serotonin receptors are activated by the neurotransmitter serotonin, which acts as their natural Ligand (biochemistry), ligand. The serotonin receptors modulate the release of many neurotransmitters, including glutamic acid, glutamate, gamma-Aminobutyric acid, GABA, dopamine, epinephrine / norepinephrine, and acetylcholine, as well as many hormones, including oxytocin, prolactin, vasopressin, cortisol, corticotropin, and substance P, among others. Serotonin receptors influence various biological and neurological processes such as aggression, anxiety, appetite, cognition, learning, memory, Mood (psychology), mood, nausea, sleep, and ...
