CP-135807 is a drug which acts as a potent and selective agonist for the 5-HT1D serotonin receptor, and is used to study the function of this receptor subtype. [1] [2]
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 and peripheral nervous systems. They mediate both excitatory and inhibitory neurotransmission. The serotonin receptors are activated by the neurotransmitter serotonin, which acts as their natural ligand.
Triptans are a family of tryptamine-based drugs used as abortive medication in the treatment of migraines and cluster headaches. This drug class was first commercially introduced in the 1990s. While effective at treating individual headaches, they do not provide preventive treatment and are not considered a cure. They are not effective for the treatment of tension–type headache, except in persons who also experience migraines. Triptans do not relieve other kinds of pain.
Methysergide, sold under the brand names Deseril and Sansert, is a monoaminergic medication of the ergoline and lysergamide groups which is used in the prophylaxis and treatment of migraine and cluster headaches. It has been withdrawn from the market in the United States and Canada due to adverse effects. It is taken by mouth.
Lisuride, sold under the brand name Dopergin among others, is a monoaminergic medication of the ergoline class which is used in the treatment of Parkinson's disease, migraine, and high prolactin levels. It is taken by mouth.
A serotonin receptor agonist is an agonist of one or more serotonin receptors. They activate serotonin receptors in a manner similar to that of serotonin, a neurotransmitter and hormone and the endogenous ligand of the serotonin receptors.
Mesulergine (INNTooltip International Nonproprietary Name) (developmental code name CU-32085) is a drug of the ergoline group which was never marketed. It acts on serotonin and dopamine receptors. Specifically, it is an agonist of dopamine D2-like receptors and serotonin 5-HT6 receptors and an antagonist of serotonin 5-HT2A, 5-HT2B, 5-HT2C, and 5-HT7 receptors.. It also has affinity for the 5-HT1A, 5-HT1B, 5-HT1D, 5-HT1F, and 5-HT5A receptors. The compound had entered clinical trials for the treatment of Parkinson's disease; however, further development was halted due to adverse histological abnormalities in rats. It was also investigated for the treatment of hyperprolactinemia (high prolactin levels).
5-hydroxytryptamine receptor 1B also known as the 5-HT1B receptor is a protein that in humans is encoded by the HTR1B gene. The 5-HT1B receptor is a 5-HT receptor subtype.
5-hydroxytryptamine (serotonin) receptor 1D, also known as HTR1D, is a 5-HT receptor, but also denotes the human gene encoding it. 5-HT1D acts on the central nervous system, and affects locomotion and anxiety. It also induces vasoconstriction in the brain.
5-Hydroxytryptamine receptor 2B (5-HT2B) also known as serotonin receptor 2B is a protein that in humans is encoded by the HTR2B gene. 5-HT2B is a member of the 5-HT2 receptor family that binds the neurotransmitter serotonin (5-hydroxytryptamine, 5-HT). Like all 5-HT2 receptors, the 5-HT2B receptor is Gq/G11-protein coupled, leading to downstream activation of phospholipase C.
CP-94253 is a drug which acts as a potent and selective serotonin 5-HT1B receptor agonist, with approximately 25× and 40× selectivity over the closely related 5-HT1D and 5-HT1A receptors. It has a range of behavioral effects, based on animal testing. The effects include the following: promoting wakefulness by increasing dopamine release in the brain; reducing food intake and promoting satiety; enhancing the reinforcing effects of cocaine; and possible antidepressant effects. A recent study found that "Regardless of sex, CP94253 decreased cocaine intake after abstinence and during resumption of SA [self-administration] and decreased cue reactivity" suggesting that agonism of the inhibitory 5-HT2B receptors may diminish the cognitive reward of cocaine usage and increased use of the drug without a period of abstinence may be a product of test subjects trying to achieve a previously rewarding experience through larger dosages of cocaine.
BRL-15,572 is a drug which acts as a selective antagonist for the serotonin receptor subtype 5-HT1D, with around 60x selectivity over other related receptors. The 5-HT1D receptor has a very similar pharmacology to the closely related 5-HT1B receptor, and most older ligands for these receptors bind to both subtypes with approximately equal affinity, so development of compounds such as BRL-15572 which are able to selectively block the 5-HT1D subtype while leaving 5-HT1B unaffected, have been a significant advance which has helped scientists in researching the function of these serotonin receptor subtypes. One function of the 5-HT1D receptor this research has revealed is its role in modulating release of the neurotransmitter glutamate in the brain, as well as functions in regulation of cerebral blood pressure which are important in the pathogenesis of migraine headaches.
SB-216641 is a drug which is a selective antagonist for the serotonin receptor 5-HT1B, with around 25x selectivity over the closely related 5-HT1D receptor. It is used in scientific research, and has demonstrated anxiolytic effects in animal studies.
GR-127935 is a drug which acts as a selective antagonist at the serotonin receptors 5-HT1B and 5-HT1D. It has little effect when given by itself but blocks the antiaggressive effect of 5-HT1B agonists, and alters release of serotonin in the brain, as well as reducing drug-seeking behaviour in cocaine addicted rats.
CGS-12066A is a drug which acts as a potent and selective agonist for the 5-HT1B receptor with lower affinity for the three 5-HT2 receptor subtypes. It is used for studying the role of the 5-HT1B receptor in various processes including perception of pain and the sleep-wake cycle.
Roxindole (EMD-49,980) is a dopaminergic and serotonergic drug which was originally developed by Merck KGaA for the treatment of schizophrenia. In clinical trials its antipsychotic efficacy was only modest but it was unexpectedly found to produce potent and rapid antidepressant and anxiolytic effects. As a result, roxindole was further researched for the treatment of depression instead. It has also been investigated as a therapy for Parkinson's disease and prolactinoma.
5-Benzyloxytryptamine (5-BT), is a tryptamine derivative which acts as an agonist at the 5-HT1D, 5-HT2 and 5-HT6 serotonin receptors, and an antagonist of TRPM8.
CP-93129 is a drug which acts as a potent and selective serotonin 5-HT1B receptor agonist, with approximately 150x and 200x selectivity over the closely related 5-HT1D and 5-HT1A receptors. It is used in the study of 5-HT1B receptors in the brain, particularly their role in modulating the release of other neurotransmitters.
PNU-142633 is an experimental drug candidate for the treatment of migraine. It exerts its effect as a selective, high affinity 5-HT1D receptor antagonist. PNU-142633 is well tolerated after oral administration.
CP-122,288 is a drug which acts as a potent and selective agonist for the 5-HT1B, 5-HT1D and 5-HT1F serotonin receptor subtypes. It is a derivative of the migraine medication sumatriptan, but while CP-122,288 is 40,000 times more potent than sumatriptan as an inhibitor of neurogenic inflammation and plasma protein extravasation, it is only twice as potent as a constrictor of blood vessels. In human trials, CP-122,288 was not found to be effective as a treatment for migraine, but its selectivity for neurogenic anti-inflammatory action over vasoconstriction has made it useful for research into the underlying causes of migraine.
