Very nonselective agonists of 5-HT receptor subtypes include ergotamine (an antimigraine), which activates 5-HT 1A, 5-HT 1D, 5-HT 1B, D 2 and norepinephrine receptors. [38] LSD (a psychedelic ) is a 5-HT 1A , 5-HT 2A , 5-HT 2C , 5-HT 5A and 5-HT 6 agonist.
The 5-HT 1 receptors are a subfamily of the 5-HT serotonin receptors that bind to the endogenous neurotransmitter serotonin (also known as 5-hydroxytryptamine, or 5-HT). [1] The 5-HT 1 subfamily consists of five G protein-coupled receptors (GPCRs) that share 40% to 63% overall sequence homology, including 5-HT 1A, 5-HT 1B, 5-HT 1D, 5-HT 1E, and 5-HT 1F. [2]
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 (5-hydroxytryptamine; 5-HT), a neurotransmitter and hormone and the endogenous ligand of the serotonin receptors.
The first selective 5-HT 1B/1D agonist, sumatriptan, was first synthesized as a subcutaneous injection, then as an oral tablets and more recently as a nasal spray, it is also available in some countries as suppositories. The subcutaneous injection is the fastest way to stop a rapidly progressing migraine attack.
Continued work led to the development of sumatriptan, now known as the first 5-HT 1 agonist, selective for the 5-HT 1D/B receptors and also the 5-HT 1F receptor with less affinity. By 1991 sumatriptan became available in clinical use in the Netherlands and in the US in 1993.
A new study compares the benefits and risks of taking GLP-1 medications for weight loss, including risks of dementia, addiction, heart disease, and gastrointestinal problems, among others.
It is an agonist at both CB1 and CB2 receptors. Also, it is an agonist at serotonin receptors (5HT1A and 5HT1B). [1] References This ...
